Financial statement analysis - Essay Example This implies that the firm has less liquidity as compared to the industry generally. However, both ratios are below the Third quartile and therefore there are companies in the industry with higher liquidity ratios than S&S Air. The company may therefore have less predictable cash flows and less access to short-term borrowing (Fridson, & Alvarez, F., 2002). A quick ratio of 0.37 is slightly higher than the industry median and this has the meaning that S&S has about the same value of inventory as the Current Liabilities. Since the company has about the same inventory as the industry median, its inventory to current liabilities ratio is more or less the same as the median for the industry. The turnover ratios as compared to the industry median are all higher and even higher than the upper quartile. This implies the efficiency of S&S Air than the whole of the industry. On the other hand, the leverage ratios are all below the industry median depicting that the firm is less dependent on debt than related companies are. In addition, the Profit Margin for the company is equal to that of the industry median while the ROA and the ROE are all above the industry median as well as the lower quartile. In short, the performance of the airline is good despite the liquidity ratios indicating that close monitoring is necessary in its operations. Using ROA of 10.61% and the retention ratio, we will be able to get the internal growth rate. The constant b= $9,233,930/$1,845,242 = 5.004; Using the internal growth rate equation: Internal growth rate = (0.1061 Ãâ€" 5.004) / [1 – (0.1061 Ãâ€" 5.004)] =113.18%. we go further to find the sustainability growth rate using ROE of 19.31% as follows; Sustainable growth rate = (0.1931 Ãâ€" 5.004) / [1 – (0.1931 Ãâ€" 5.004)] = 28.65. Without outside financing of any sort, the company is able to achieve a growth rate of 113.18% and the growth rate would even be enormously higher when it gets funding externally (Robinson,

Licensed Futurist - Essay Example In his DVD, An Inconvenient Truth, he talks about how our entire world is changing. The challenge for Gore is that the people who need to listen and do something about it on a larger scale, are turning a deaf ear. Many so-called scientists want to say that there is no such thing as Global Warming. However, everyone is experiencing climate changes. We have more damaging storms and many areas that should have snow in the winter have spring days. In some areas, the summers are hotter than ever before and we are losing our oceans. We are not paying attention to this because we do not think that it is affecting us. However, everything that happens to the planet will have an effect on us eventually. Another area where we are not watching is what is happening in technology. With cell phones alone, we have a device that baby sits, takes away time from the family and does everything but get up and dance; who knows, someone may be working on that one right now! We are told that many discoveries in telecommunications and other technology are good for us. A prediction that "there will be intelligent electronic systems almost everywhere" (Hall, 2007, p. 1) is a common prediction. Why? Because ewe are becoming so advanced with our technology that it is difficult to embrace all of it at once. One prediction in this area that we have already realized is the Internet connections anywhere we go. Many restaurants, hospital waiting rooms, even Burger King has a wireless connection today. Although this is a great idea, when we embrace it to the fullest, we will move away from our children and families in favor of talking on the phone or being on the computer most of the time. According to Rub ner (2010), some experts predict that we will be wearing mobile electronics in our clothing; Rubner says we will not need computers eventually because we will be wearing them. Hall adds to what Rubner says and we can expect live

Internet Protocol (VoIP) Technology

Internet Protocol (VoIP) Technology Abstract Voice over Internet Protocol (VoIP) technology has come of age and is quickly gaining momentum on Broadband networks. VoIP packetizes phone calls through the same routes used by network and Internet traffic and is consequently prone to the same cyber threats that plague data networks today. It presents lower cost and greater flexibility for a venture but presents considerable security challenges. Many solutions for VoIP security are projected, however these solutions should take into account the real-time constriction of voice service and their methods be supposed to address probable attacks and overhead related with it. One of these solutions is to make use of Firewalls, which implement a security strategy by examining and straining traffic arriving or leaving from a protected network. This is normally done by evaluating an incoming packet to a set of policies and performing the corresponding rule action, which is accept or reject. Undesirably packet examinations can require considerable interruptions on traffic due to the difficulty and size of policies. Consequently, improving firewall performance is significant for the VoIP networks. In this paper, we propose a new firewall deign that is able to dynamically update firewall policy based on Neural Network and achieve packet examinations under rising traffic loads, higher traffic speeds, and stringent QoS necessities. The design consists of several firewalls configured in parallel that jointly impose a defense strategy. Every firewall outfits part of the rule and incoming packets is processed through all the firewalls concurrently. Once the neural network is trained, it continuously updates the firewall policy using the selected parameters to perform its evaluation. Since many firewalls are utilized to process each packet, the proposed parallel firewall system has considerably lower delays and a higher throughput than other firewalls. Introduction Voice over IP the transmission of voice over traditional packet-switched IP networks is one of the hottest trends in telecommunications. Although most computers can provide VoIP and many offer VoIP applications, the term â€Å"voice over IP† is typically associated with equipment that lets users dial telephone numbers and communicate with parties on the other end who have a VoIP system or a traditional analog telephone. (The sidebar, â€Å"Current voice-over-IP products,† describes some of the products on the market today.) As with any new technology, VoIP introduces both opportunities and problems. It offers lower cost and greater flexibility for an enterprise but presents significant security challenges. As with any new technology, VoIP introduces both opportunities and problems.. Security administrators might assume that because digitized voice travels in packets, they can simply plug VoIP components into their already secured networks and get a stable and secure voice network. Quality of service (QoS) is fundamental to a VoIP networks operation. A VoIP application is much more sensitive to delays than its traditional data counterparts. Latency turns traditional security measures into double-edged swords for VoIP. Tools such as encryption and firewall protection can help secure the network, but they also produce significant delay. Latency isnt just a QoS issue, but also a security issue because it increases the systems susceptibility to denial-of-service attacks. To succeed in a VoIP network, a DoS attack need not completely shut down the system, but only delay voice packets for a fraction of a second. The necessary impediment is even less when latency-producing security devices are slowing down traffic. As described in the introduction, parallelization offers a Scalable technique for improving the performance of network firewalls. Using this approach an array of m firewalls processes packets in parallel. However, the two designs depicted in differ based on what is distributed: packets or rules. The design was Consisted of multiple identical firewalls connected in parallel, each firewall j in the system implements a local policy Rj where Rj = R. Arriving packets are distributed across the firewalls for processing (one packet is sent to one firewall), allowing different packets to be processed in parallel. Since each packet is processed using the policy Rj = R, policy integrity is maintained. A neural network is a group of interconnected nodes. The well-known example is the human brain, the most complicated and difficult neural network. We can make very fast and reliable choice in portion of a second. In the face of the clear neatness of usual thinking, outcome are usually not-white and -black or binary, but quite engage a broad diversity of alert and secreted inputs, we have an wonderful facility to recognize well-known patterns as well as extraordinary patterns more or less directly, the neural network approach effort to reproduce the way humans visually the usual consumer speedily studies to identify spam from correct connection. The reason for this is generally since we illustration our brains both on reason to a broad variety of message content and the brain learns to create lightning-fast, very exact guess. The capacity of utilizing packet changed networks as a transmit standard for real-time tone of voice connections has drawn broad awareness among both research and possible communities alike. The current progress in speech conventions and high speed information communication technology hold up the notice in equipment such as voice over Internet protocol (VoIP), the mathematical character of information interchange and the energetic routing method engaged in packet-switched networks outcomes in an unbalanced network delay (jitter) practiced by IP packets. [chris miller]. Although a data-parallel firewall can achieve higher throughput than a traditional (single machine) firewall, it suffers from two major disadvantages. First, stateful inspection requires all traffic from a certain connection or exchange to traverse the same firewall. Successful connection tracking is difficult to perform at high speeds using the data-parallel approach Second, distributing packets is only beneficial when each firewall in the array has a significant amount of traffic to process (never idle), which only occurs under high traffic loads. In order to understand parity in a carrier network maintaining secrecy, the studying techniques to know excluded traffic from partial information, such as the header information and show pattern of a series of packets. The propose a traffic credit technique for a direct request which uses mathematical information such as incidence of packet coming. This method is to be used for stop idea by recognize traffic generate by not only VoIP but video request as well. By using this method, travel that is clearly mediator excluded is not needed, the quality of traffic that is classified into best services, such as urgent situation message and moving sharing, is certain, and, for best effort services, suitable operation are perform so that capital can not be busy by a few edge, so as to understand fairness in symbol services. This advance is to applications that generate traffic from the presentation of the traffic. It can be underground into the following three types regarding the granularity of the observed traffic. [Toshiya Okabe Tsutomu Kitamura 2006]. Transaction-level behavior This approach is a system focus on the skin of an application-level action, such as an HTTP request message, and its response, an HTTP response message or MAIL message. With this progress, a request is indirect from the change patterns, the size of each message. A method to order maintain by the time-series changes in the size of messages. These techniques are useful for sense a signal protocol, but are not suitable for discovery of real-time message traffic whose features are boring and last for a fairly long time. [Toshiya Okabe Tsutomu Kitamura 2006] Flow-level behavior This method is to make out an application from mathematical information such as the inter-arrival time, period of the run, packet size. Here, a run is defined as a sequence of packets having a common source address, source port, destination address, destination port and transport protocol. It is extract skin of size data message request flows, such as HTTP, FTP and SMTP graceful from side to side a network, in order to create workload for a network simulator and classify traffic into three lessons, bulk data message such as FTP, informal message. [Toshiya Okabe Tsutomu Kitamura 2006] Packet-level behavior This is techniques that identify a request from the header or load of a single packet. A group method mainly based on port facts has been used but its efficiency has been lost due to the arrival of P2P applications that illegitimately use chance port numbers and port numbers for HTTP to traverse a Firewall. [Toshiya Okabe Tsutomu Kitamura 2006]. Average packet length and variation The result of extract skin correlated to the normal packet size and difference in packet size. Difference in packet size here indicates the number of types of packet size for a request whose packet size is fixed. It is the result of take out the skin of voice applications. The packet size of the voice application is lesser than that of the other application. [ Takayuki Shizuno 2006] As with any new knowledge, VoIP introduce both opportunity and problems. It offers lesser cost and greater give for an project but presents significant security challenge. Security administrator strength suppose that because digitized voice actions in packets, the plug VoIP mechanism into their previously protected networks and get a stable and secure voice network address translation (NAT), and most VoIP mechanism have counterpart in data network, VoIPs presentation stress mean you must extra ordinary network software and hardware with special VoIP mechanism. Packet network depend on many configurable bound: IP and physical addresses of say terminal of routers and firewalls. VoIP networks add specific software, to place and route calls. Many network bound are recognized with passion each time a network part is restart or when a VoIP phone is restart or added to the network.. So many nodes in a VoIP network have dynamically configurable bound; But VoIP systems have much stricter presentation constraint than data networks with important implication for security. [ Takayuki Shizuno 2006]. Quality-of-service issues Quality of service is basic to a VoIP networks process. A VoIP request is much more responsive to delay than its customary data matching part. In the VoIP language, this is the latency problem. Latency turns conventional safety measured. Tools such as encryption and firewall defense can help secure the system, but they also set up important delay. Latency isnt just a QoS issue, but also a safety issue because it increases the system weakness to denial-of-service attacks. To do well in a VoIP network, a DoS attack need not totally shut down the system, but only delay voice packets for a part of a second. The necessary let is even less when latency-producing security devices are slowing down traffic. Another QoS issue jitter, refers to no uniform delays that can cause packets to turn up and be process out of series. The Real-Time Transport Protocol (RTP), which is used to move voice media, so packets received out of order cant be reassembled at the move level, but must be rearrange at the request level, introduce major above your head. When packets turn up in order, high jitter causes them to arrive at their target in spurts. To control jitter, network expensive can use buffers and implement QoS-supporting network elements that let VoIP packets when larger data packets are listed in front of them. The buffer can use one of several plans to resolve when to let go voice data, counting several scheme that adapt the payout time also encompass packet loss. In addition to the usual packet loss issue related with data networks, even VoIP packets that reach their target can be make useless by latency and jitter. [thomas j. walsh and d. richard kuhn ]. Project Background Neural network is the bury order growing fast in current years. It is jointly of a massive deal of easy giving out units of neuron with providing connect as a neural network. It can replicate the information distribution task of human being brain, with huge talent of nonlinear estimate, consecutively storage, large-scale similar development, and self-training lessons. The information distribution in the neural network is recognizing by the communication between the neurons, and the storage of data and in progression as increase physical interconnection of the network parts. [, a. shelestov, v. pasechnik, a. sidorenko, n. kussul , 2006]. A parallel firewall (also called a load-balancing firewall) is a scalable approach for increasing the speed of inspecting network traffic. As seen in figure .the system consists of multiple identical firewalls connected in parallel. Each firewall in the system implements the complete security policy and arriving packets are distributed across the firewalls such that only one firewall processes any given packet. How the load-balancing algorithm distributes packets is vital to the system and typically implemented as a high-speed switch in commercial products. Although parallel firewalls achieve a higher throughput than traditional firewalls and have a redundant design, the performance benefit is only evident under high traffic loads. Furthermore, stateful inspection requires all traffic from a certain connection or exchange to traverse the same firewall, which is difficult to perform at high speeds. This paper introduces a new scalable parallel firewall architecture designed for increasing network speeds and traffic loads. The design consists of multiple firewalls where each firewall implements only a portion of the security policy. Since the policy is divided across the firewalls, rule distribution guidelines are provided that maintains integrity, ensuring the new parallel design and a traditional single firewall always reach the same decision. Unlike the previous parallel design, When a packet arrives to the new architecture it is processed by every firewall in parallel, thus the processing time required per packet is reduced. Simulation results for the new architecture (consisting of four firewalls) yielded a 74% reduction in processing time as compared to other parallel firewall designs. Furthermore, the proposed architecture can provide stateful inspections since a packet is processed by every firewall. Therefore, the new parallel design is a scalable solution that can offer better performance and more capabilities than other designs. In list-based rule symbol, when packets arrive at a firewall, it is in sequence check against the system in the rule list until a match is found or attainment the end of the list. Then, the parallel action is applied to mass or pass the packet. To make the policy complete of match is always found for each packet, the computational difficulty of the sort process depends on the length of rule as the depth of result a matched rule in the rule list. Apply more composite policy can result in major traffic wait which is not only a presentation block in high speed environment but also can make it weaker to rejection of service attacks. Moreover, attractive the filter time is more difficult for multimedia applications that require firm quality of service promise. Although hardware solutions can very much decrease the packet giving out time, they are costly for large policy and improvement hardware may not be suitable in inheritance systems. on the other hand, better data structure for inner policy symbol and better search mechanism have been planned to provide relatively and effective solution to benefit on hand hardware systems. The rules are group to allow multidimensional search by at once eliminate multiple rules with few comparison. While tries have shown great agree in improving the search time, the storage condition and difficulty in maintain try and policy honesty increases as more rules . Moreover, a policy trie does not take into report the traffic personality. In a method for trie sorting is proposed that sustain the policy honesty while reorder rules for unreliable traffic situation. The number of contrast as compare to the original trie. Traffic-aware optimization of list-based firewalls has been addressed in rules are assigned matching probability that depend on the traffic information. Other firewall models have been planned to signify and analyze policy whether for central or distributed firewall architectures with main focus on identify rule conflicts and variance; Wireless local (WLAN) and wireless personal (WPAN) area networks are being used increasingly to implement VoIP forces. The main drives for using these architectures are user mobility. Behind realible real-time repair is one of the major concerns for generally use of VoIP in these wireless IPbased networks and safety is now getting the notice of researchers. The security and efficiency are consisting requirements. [El-Sayed M. El-Alfy and Shokri Z. Selim 2007] Literature Review Introduction: Literature Review is the process of finding information for help on searching for resources on the Internet. Reading intensively in the chosen topic area is essential, but the task can prove daunting if they do not approach it in a systematic way. The continuous number of high-profile Internet security breeches reported in the mass media shows that despite an emphasis on security processes that there is still a gap between theory and practice. Not only is there a need to develop better software engineering processes but also theoretical security improvements need to find their way into real systems. Software design patterns are defined as â€Å"descriptions of communicating objects and classes that are customized to solve a general design problem in a particular context†. As software design patterns have proven their value in the development of production software, they are a promising new approach to help in both the theoretical development and practical implementation of better security processes. First, many/most software developers have only a limited knowledge of security processes and patterns are a proven way to improve their understanding. Second, patterns work against â€Å"reinventing-the-wheel† to promote learning best practices from the larger community to save time, effort, and money with easily accessible and validated examples. Third, code can be reused since the same security patterns arise in many different contexts Investigating existing resources in our area of research will generally cover three areas: Exploratory investigations, as part of the development and evaluation of possible topics in an area Investigation is some depth, sufficient to support a formal research and dissertation proposal Complete research that is described in the literature / research section of the dissertation. [from Writing the Doctoral Dissertation, To Author names] 2. Related Research Work Available: Wireless local (WLAN) and wireless personal (WPAN) area networks are being used progressively to implement VoIP services. The main motivation for using these architectures are user mobility, setup flexibility, increasing transmission rate and low costs, despite this convergence depends on the answers of several technical problems Supporting reliable real-time service is one of the major concerns for widely deployment of VoIP in these ireless IPbased networks and security is now receiving the attention of researchers. The problem of offering security to WLAN and WPAN is that security does not come for free and, security and efficiency are conflicting requirements. The introduction of a security mechanism such as the IPSec encryption-engine to overcome these issues impacts directly in the speech quality of established calls and in the channel capacity. Moreover, largely deployed radio technology standards as IEEE 802.11 and Bluetooth used to achieve wireless connectivity have several constraints when delivering real-time traffic, as transmission errors at the channel, introducing delay and loss which with security mechanisms impact can lead to low quality VoIP calls. Although these technologies offer some security mechanisms, they have some flaws which need to be addressed by an additional level of security. In this paper we focus on the IPSec protocol to achieve the data secrecy due to its widely deployment and implementation of many encryption algorithms. During final decades information technology founded on the computer networks take part in an essential role in different areas of human being action. Troubles of huge importance are assigned on them, such as maintenance, communication and mechanization of information processing. The safety level of processed information is able to differ from private and viable to military and state secret. Herewith the destruction of the information secrecy, reliability and accessibility may cause the spoil to its proprietor and contain important unattractive consequences. Hence the trouble of information safety is concerned. Many associations and companies expand safety facilities that need important aids. In additional, the impracticality of creating wholly protected system is a recognized fact – it will always hold faults and  «gaps » in its understanding. To guard computer systems such familiarized mechanisms as classification and verification, methodologies of the delimitation and limit of the access to data and cryptographic techniques are applied. But they hold following drawbacks: †¢ Disclosure from interior users with spiteful purpose; †¢ Complexity in access separation caused by data sources globalization, which cleans away difference between personal and foreign topics of the system; †¢ Diminution of efficiency and communication complexity by reason of methods for access control to the sources, for occasion, in e-commerce; †¢ Effortlessness of passwords description by crating arrangements of simple users relations. Hence classification and audit systems are utilized beside with these methods. between them are interruption. Intrusion Detection Systems (IDS). IDS are generally separated to systems detecting previously identified attacks (mishandling exposure systems) and variance exposure systems registering the life cycle differences of the computer system from its usual (distinctive) action. Besides, IDS are divided to network-based and host-based category by data source. Network-based IDS examine network dataflow, caring its members, almost not moving the output of their work. Network-based systems do not utilize data about progression from divide workstation. A firewall is a mixture of hardware and software used to put into practice a security policy leading the flow of network traffic between two or more networks. In its simplest form, a firewall acts as a safety barrier to control traffic and manage links between internal and external network hosts. The actual means by which this is able varies and ranges from packet sort and proxy service to stateful examination methods. A more difficult firewall may hide the topology of the network it is employed to keep, Firewalls have recognized to be useful in trade with a large number of pressure that create from outer a network. They are becoming ever-present and necessary to the action of the network. The constant growth of the Internet, coupled with the increasing difficulty of attacks, however, is placing further stress and difficulty on firewalls design and management. . [ Subrata Acharya, Jia Wang, Albert Greenberg 2006] Furthermore, the need to deal with large set of varied safety policy and rules impose additional load on firewalls, thus depiction the presentation of the firewall highly serious to enforce the network safety policy. In this context, the defense that a firewall provides only the policies it is configured to execute, but evenly importantly the speed at which it enforces these policy. Under attack or deep load, firewalls can simply become a bottleneck. As the network size, bandwidth, and giving out power of networked hosts carry on increasing, there is a high demand for optimizing firewall operation for improved performance. [ Subrata Acharya, Jia Wang, Albert Greenberg 2006] Multi-dimensional firewall research group of people to focus on mounting various optimizations to make firewalls more resourceful and steady. In spite of significant progress in the design of firewalls, the techniques for firewall optimization remains static and fail to get used to to the always varying dynamics of the network. This is frequently due to their failure to take into account the traffic individuality by the firewall, such as source and purpose, service requests and the resultant action taken by the firewall in reply to these requests. Moreover, current firewall designs do not support adaptive difference discovery and counter measure device. As a result, they run the risk to become unbalanced under attack. The object of this paper is to address the above failing and develop a sound and effective toolset to hasten firewall operation and adapt its performance to the dynamically altering network traffic individuality. Achieve this goal, however is tough, as the number of policy and safety rules a firewall has to enforce for enterprise network. In addition, there is a need for preserve high policy addition. This is further compounded by the limited resources of firewalls relation to the increased ability of the network to process and forward traffic at very high speed. [ Subrata Acharya, Jia Wang, Albert Greenberg 2006] Methodolgy Network Firewall Parallelization Firewall parallelization is a scalable move toward for attaining the speed of system traffic assessment [Carsten Benecke,1999] necessary for improved network paces and traffic loads. In this section data parallel [Carsten Benecke,1999] and function parallel designs [Errin W. Fulp,2002] for parallel firewalls are explained. Similar to their distributed computing descriptions necessitate, data parallel partition the information set across the array of firewalls, while function parallel distributes the work set across the array of firewalls. The data parallel technique is a scalable substitute to a single firewall that permits for better throughput potentials. Function parallel techniques can diminish the dispensation time necessary on any firewall node yielding enhanced presentation. In addition, unlike data parallel designs, the proposed function parallel architecture can offer stateful assessments. This proposal shows that function parallel designs are scalable solution that can offer better performance and more facilities than other designs. Parallel Firewall Architecture: Function Parallel Firewall [W. Fulp and Ryan J] consists of multiple firewalls coupled in parallel and a gatedevice, as shown in figure. Every firewall in the system outfits a local strategy, where incoming packets are disseminated across the firewalls for processing (one packet is sent to one firewall), permitting different packets to be processed in parallel. Because every packet is processed by the policy, reliability is maintained. The common operation of the scheme can be described as follows. When a packet reaches to the function-parallel system it is promoted to all the firewall and the gate. Each firewall processes the packet with its local policy, as well as any state information. The firewall then signals the gate representing either no match was found, or offers the rule number and action if a match was found. As local policies are a division of the original, a no-matchis a suitable answer and is necessary for the function-parallel design. The gate stores the outcomes and establishes the final action to achieve on the packet using the Firewall rule. Parallel Firewall System Components A function parallel system consists of a collection of firewall nodes. Packets are replicated to all firewall nodes as they go into the system. Policies must be disseminated across the system such that they specify an accept set identical to the original accept set and no local policys accept set can overlap another local policys accept set. The received packets are then combined into one stream to arrive at the destination. A control plane is also essential to permit common system management. Firewall Nodes The firewall nodes contain a network interface card for every network input and control plane. This design implements the firewall nodes as PCs running the Linux operating system with a kernel that supports iptables. It must be stated that iptables was selected for an profitable feature of provisional rule dispensation. By default there are built-in sets of policies called chains divided by whether they hold traffic bound for procedures pay attention on local input devices, proposed for routing throughout the system to another network or outbound and supplied from a local procedure. In addition iptables has support for user defined chains. The user defined chains can be called if a packet matches a rule in a sequence. Packet Duplicator Packet Duplicator is essential on all links which will input traffic into the system. In Ethernet networks packet duplication is easily achieved with a network hub because any packets arriving on a hub port are copied to all other hub ports. But, in high speed networks hub technology is not presented. The only available devices in high speed networks to attain duplication are network taps. These devices are used for duplicating network traffic, usually used in intrusion detection systems that necessitate network monitoring. Control Plane In a single firewall system, protected customer communication can be offered through the prerequisite of physical existence. To generate a protected technique of management, communication to the collection of firewall nodes can be quarantined on a separate control plane. In the simplest form this entails a separate subnet which all firewall nodes survive on. Component Integration Joining these components into a functional design can be cut down into two network representations. The first utilizes simply one packet duplicator and can simply offer protection for traffic from one source. The second topology allows two networks to communicate bi-directionally through the system. One-Directional System This technique only thinks about packets traveling in one direction; for example, only packets are moving from source to destination. The collection of firewall nodes use the same IP address and MAC address and all will take the incoming network interface card in immoral mode. All but one firewall node will allow existing networking equipment outside of the system to cooperate with no alterations. The firewall node which does respond to user requirements can also be permitted to respond to ICMP ping requests in order to formulate the system additional compatible. For the outgoing network interface cards, any IP or MAC can be used as long as it permits communication with the destination. Bi-directional System The Bi-directional system considers packets moving in both directions; for example, packets traveling from source to destination and then back to source.

The current progress in speech conventions and high speed information communication technology hold up the notice in equipment such as voice over Internet protocol (VoIP), the mathematical character of information interchange and the energetic routing method engaged in packet-switched networks outcomes in an unbalanced network delay (jitter) practiced by IP packets. [chris miller]. Although a data-parallel firewall can achieve higher throughput than a traditional (single machine) firewall, it suffers from two major disadvantages. First, stateful inspection requires all traffic from a certain connection or exchange to traverse the same firewall. Successful connection tracking is difficult to perform at high speeds using the data-parallel approach Second, distributing packets is only beneficial when each firewall in the array has a significant amount of traffic to process (never idle), which only occurs under high traffic loads. In order to understand parity in a carrier network maintaining secrecy, the studying techniques to know excluded traffic from partial information, such as the header information and show pattern of a series of packets. The propose a traffic credit technique for a direct request which uses mathematical information such as incidence of packet coming. This method is to be used for stop idea by recognize traffic generate by not only VoIP but video request as well. By using this method, travel that is clearly mediator excluded is not needed, the quality of traffic that is classified into best services, such as urgent situation message and moving sharing, is certain, and, for best effort services, suitable operation are perform so that capital can not be busy by a few edge, so as to understand fairness in symbol services. This advance is to applications that generate traffic from the presentation of the traffic. It can be underground into the following three types regarding the granularity of the observed traffic. [Toshiya Okabe Tsutomu Kitamura 2006]. Transaction-level behavior This approach is a system focus on the skin of an application-level action, such as an HTTP request message, and its response, an HTTP response message or MAIL message. With this progress, a request is indirect from the change patterns, the size of each message. A method to order maintain by the time-series changes in the size of messages. These techniques are useful for sense a signal protocol, but are not suitable for discovery of real-time message traffic whose features are boring and last for a fairly long time. [Toshiya Okabe Tsutomu Kitamura 2006] Flow-level behavior This method is to make out an application from mathematical information such as the inter-arrival time, period of the run, packet size. Here, a run is defined as a sequence of packets having a common source address, source port, destination address, destination port and transport protocol. It is extract skin of size data message request flows, such as HTTP, FTP and SMTP graceful from side to side a network, in order to create workload for a network simulator and classify traffic into three lessons, bulk data message such as FTP, informal message. [Toshiya Okabe Tsutomu Kitamura 2006] Packet-level behavior This is techniques that identify a request from the header or load of a single packet. A group method mainly based on port facts has been used but its efficiency has been lost due to the arrival of P2P applications that illegitimately use chance port numbers and port numbers for HTTP to traverse a Firewall. [Toshiya Okabe Tsutomu Kitamura 2006]. Average packet length and variation The result of extract skin correlated to the normal packet size and difference in packet size. Difference in packet size here indicates the number of types of packet size for a request whose packet size is fixed. It is the result of take out the skin of voice applications. The packet size of the voice application is lesser than that of the other application. [ Takayuki Shizuno 2006] As with any new knowledge, VoIP introduce both opportunity and problems. It offers lesser cost and greater give for an project but presents significant security challenge. Security administrator strength suppose that because digitized voice actions in packets, the plug VoIP mechanism into their previously protected networks and get a stable and secure voice network address translation (NAT), and most VoIP mechanism have counterpart in data network, VoIPs presentation stress mean you must extra ordinary network software and hardware with special VoIP mechanism. Packet network depend on many configurable bound: IP and physical addresses of say terminal of routers and firewalls. VoIP networks add specific software, to place and route calls. Many network bound are recognized with passion each time a network part is restart or when a VoIP phone is restart or added to the network.. So many nodes in a VoIP network have dynamically configurable bound; But VoIP systems have much stricter presentation constraint than data networks with important implication for security. [ Takayuki Shizuno 2006]. Quality-of-service issues Quality of service is basic to a VoIP networks process. A VoIP request is much more responsive to delay than its customary data matching part. In the VoIP language, this is the latency problem. Latency turns conventional safety measured. Tools such as encryption and firewall defense can help secure the system, but they also set up important delay. Latency isnt just a QoS issue, but also a safety issue because it increases the system weakness to denial-of-service attacks. To do well in a VoIP network, a DoS attack need not totally shut down the system, but only delay voice packets for a part of a second. The necessary let is even less when latency-producing security devices are slowing down traffic. Another QoS issue jitter, refers to no uniform delays that can cause packets to turn up and be process out of series. The Real-Time Transport Protocol (RTP), which is used to move voice media, so packets received out of order cant be reassembled at the move level, but must be rearrange at the request level, introduce major above your head. When packets turn up in order, high jitter causes them to arrive at their target in spurts. To control jitter, network expensive can use buffers and implement QoS-supporting network elements that let VoIP packets when larger data packets are listed in front of them. The buffer can use one of several plans to resolve when to let go voice data, counting several scheme that adapt the payout time also encompass packet loss. In addition to the usual packet loss issue related with data networks, even VoIP packets that reach their target can be make useless by latency and jitter. [thomas j. walsh and d. richard kuhn ]. Project Background Neural network is the bury order growing fast in current years. It is jointly of a massive deal of easy giving out units of neuron with providing connect as a neural network. It can replicate the information distribution task of human being brain, with huge talent of nonlinear estimate, consecutively storage, large-scale similar development, and self-training lessons. The information distribution in the neural network is recognizing by the communication between the neurons, and the storage of data and in progression as increase physical interconnection of the network parts. [, a. shelestov, v. pasechnik, a. sidorenko, n. kussul , 2006]. A parallel firewall (also called a load-balancing firewall) is a scalable approach for increasing the speed of inspecting network traffic. As seen in figure .the system consists of multiple identical firewalls connected in parallel. Each firewall in the system implements the complete security policy and arriving packets are distributed across the firewalls such that only one firewall processes any given packet. How the load-balancing algorithm distributes packets is vital to the system and typically implemented as a high-speed switch in commercial products. Although parallel firewalls achieve a higher throughput than traditional firewalls and have a redundant design, the performance benefit is only evident under high traffic loads. Furthermore, stateful inspection requires all traffic from a certain connection or exchange to traverse the same firewall, which is difficult to perform at high speeds. This paper introduces a new scalable parallel firewall architecture designed for increasing network speeds and traffic loads. The design consists of multiple firewalls where each firewall implements only a portion of the security policy. Since the policy is divided across the firewalls, rule distribution guidelines are provided that maintains integrity, ensuring the new parallel design and a traditional single firewall always reach the same decision. Unlike the previous parallel design, When a packet arrives to the new architecture it is processed by every firewall in parallel, thus the processing time required per packet is reduced. Simulation results for the new architecture (consisting of four firewalls) yielded a 74% reduction in processing time as compared to other parallel firewall designs. Furthermore, the proposed architecture can provide stateful inspections since a packet is processed by every firewall. Therefore, the new parallel design is a scalable solution that can offer better performance and more capabilities than other designs. In list-based rule symbol, when packets arrive at a firewall, it is in sequence check against the system in the rule list until a match is found or attainment the end of the list. Then, the parallel action is applied to mass or pass the packet. To make the policy complete of match is always found for each packet, the computational difficulty of the sort process depends on the length of rule as the depth of result a matched rule in the rule list. Apply more composite policy can result in major traffic wait which is not only a presentation block in high speed environment but also can make it weaker to rejection of service attacks. Moreover, attractive the filter time is more difficult for multimedia applications that require firm quality of service promise. Although hardware solutions can very much decrease the packet giving out time, they are costly for large policy and improvement hardware may not be suitable in inheritance systems. on the other hand, better data structure for inner policy symbol and better search mechanism have been planned to provide relatively and effective solution to benefit on hand hardware systems. The rules are group to allow multidimensional search by at once eliminate multiple rules with few comparison. While tries have shown great agree in improving the search time, the storage condition and difficulty in maintain try and policy honesty increases as more rules . Moreover, a policy trie does not take into report the traffic personality. In a method for trie sorting is proposed that sustain the policy honesty while reorder rules for unreliable traffic situation. The number of contrast as compare to the original trie. Traffic-aware optimization of list-based firewalls has been addressed in rules are assigned matching probability that depend on the traffic information. Other firewall models have been planned to signify and analyze policy whether for central or distributed firewall architectures with main focus on identify rule conflicts and variance; Wireless local (WLAN) and wireless personal (WPAN) area networks are being used increasingly to implement VoIP forces. The main drives for using these architectures are user mobility. Behind realible real-time repair is one of the major concerns for generally use of VoIP in these wireless IPbased networks and safety is now getting the notice of researchers. The security and efficiency are consisting requirements. [El-Sayed M. El-Alfy and Shokri Z. Selim 2007] Literature Review Introduction: Literature Review is the process of finding information for help on searching for resources on the Internet. Reading intensively in the chosen topic area is essential, but the task can prove daunting if they do not approach it in a systematic way. The continuous number of high-profile Internet security breeches reported in the mass media shows that despite an emphasis on security processes that there is still a gap between theory and practice. Not only is there a need to develop better software engineering processes but also theoretical security improvements need to find their way into real systems. Software design patterns are defined as â€Å"descriptions of communicating objects and classes that are customized to solve a general design problem in a particular context†. As software design patterns have proven their value in the development of production software, they are a promising new approach to help in both the theoretical development and practical implementation of better security processes. First, many/most software developers have only a limited knowledge of security processes and patterns are a proven way to improve their understanding. Second, patterns work against â€Å"reinventing-the-wheel† to promote learning best practices from the larger community to save time, effort, and money with easily accessible and validated examples. Third, code can be reused since the same security patterns arise in many different contexts Investigating existing resources in our area of research will generally cover three areas: Exploratory investigations, as part of the development and evaluation of possible topics in an area Investigation is some depth, sufficient to support a formal research and dissertation proposal Complete research that is described in the literature / research section of the dissertation. [from Writing the Doctoral Dissertation, To Author names] 2. Related Research Work Available: Wireless local (WLAN) and wireless personal (WPAN) area networks are being used progressively to implement VoIP services. The main motivation for using these architectures are user mobility, setup flexibility, increasing transmission rate and low costs, despite this convergence depends on the answers of several technical problems Supporting reliable real-time service is one of the major concerns for widely deployment of VoIP in these ireless IPbased networks and security is now receiving the attention of researchers. The problem of offering security to WLAN and WPAN is that security does not come for free and, security and efficiency are conflicting requirements. The introduction of a security mechanism such as the IPSec encryption-engine to overcome these issues impacts directly in the speech quality of established calls and in the channel capacity. Moreover, largely deployed radio technology standards as IEEE 802.11 and Bluetooth used to achieve wireless connectivity have several constraints when delivering real-time traffic, as transmission errors at the channel, introducing delay and loss which with security mechanisms impact can lead to low quality VoIP calls. Although these technologies offer some security mechanisms, they have some flaws which need to be addressed by an additional level of security. In this paper we focus on the IPSec protocol to achieve the data secrecy due to its widely deployment and implementation of many encryption algorithms. During final decades information technology founded on the computer networks take part in an essential role in different areas of human being action. Troubles of huge importance are assigned on them, such as maintenance, communication and mechanization of information processing. The safety level of processed information is able to differ from private and viable to military and state secret. Herewith the destruction of the information secrecy, reliability and accessibility may cause the spoil to its proprietor and contain important unattractive consequences. Hence the trouble of information safety is concerned. Many associations and companies expand safety facilities that need important aids. In additional, the impracticality of creating wholly protected system is a recognized fact – it will always hold faults and  «gaps » in its understanding. To guard computer systems such familiarized mechanisms as classification and verification, methodologies of the delimitation and limit of the access to data and cryptographic techniques are applied. But they hold following drawbacks: †¢ Disclosure from interior users with spiteful purpose; †¢ Complexity in access separation caused by data sources globalization, which cleans away difference between personal and foreign topics of the system; †¢ Diminution of efficiency and communication complexity by reason of methods for access control to the sources, for occasion, in e-commerce; †¢ Effortlessness of passwords description by crating arrangements of simple users relations. Hence classification and audit systems are utilized beside with these methods. between them are interruption. Intrusion Detection Systems (IDS). IDS are generally separated to systems detecting previously identified attacks (mishandling exposure systems) and variance exposure systems registering the life cycle differences of the computer system from its usual (distinctive) action. Besides, IDS are divided to network-based and host-based category by data source. Network-based IDS examine network dataflow, caring its members, almost not moving the output of their work. Network-based systems do not utilize data about progression from divide workstation. A firewall is a mixture of hardware and software used to put into practice a security policy leading the flow of network traffic between two or more networks. In its simplest form, a firewall acts as a safety barrier to control traffic and manage links between internal and external network hosts. The actual means by which this is able varies and ranges from packet sort and proxy service to stateful examination methods. A more difficult firewall may hide the topology of the network it is employed to keep, Firewalls have recognized to be useful in trade with a large number of pressure that create from outer a network. They are becoming ever-present and necessary to the action of the network. The constant growth of the Internet, coupled with the increasing difficulty of attacks, however, is placing further stress and difficulty on firewalls design and management. . [ Subrata Acharya, Jia Wang, Albert Greenberg 2006] Furthermore, the need to deal with large set of varied safety policy and rules impose additional load on firewalls, thus depiction the presentation of the firewall highly serious to enforce the network safety policy. In this context, the defense that a firewall provides only the policies it is configured to execute, but evenly importantly the speed at which it enforces these policy. Under attack or deep load, firewalls can simply become a bottleneck. As the network size, bandwidth, and giving out power of networked hosts carry on increasing, there is a high demand for optimizing firewall operation for improved performance. [ Subrata Acharya, Jia Wang, Albert Greenberg 2006] Multi-dimensional firewall research group of people to focus on mounting various optimizations to make firewalls more resourceful and steady. In spite of significant progress in the design of firewalls, the techniques for firewall optimization remains static and fail to get used to to the always varying dynamics of the network. This is frequently due to their failure to take into account the traffic individuality by the firewall, such as source and purpose, service requests and the resultant action taken by the firewall in reply to these requests. Moreover, current firewall designs do not support adaptive difference discovery and counter measure device. As a result, they run the risk to become unbalanced under attack. The object of this paper is to address the above failing and develop a sound and effective toolset to hasten firewall operation and adapt its performance to the dynamically altering network traffic individuality. Achieve this goal, however is tough, as the number of policy and safety rules a firewall has to enforce for enterprise network. In addition, there is a need for preserve high policy addition. This is further compounded by the limited resources of firewalls relation to the increased ability of the network to process and forward traffic at very high speed. [ Subrata Acharya, Jia Wang, Albert Greenberg 2006] Methodolgy Network Firewall Parallelization Firewall parallelization is a scalable move toward for attaining the speed of system traffic assessment [Carsten Benecke,1999] necessary for improved network paces and traffic loads. In this section data parallel [Carsten Benecke,1999] and function parallel designs [Errin W. Fulp,2002] for parallel firewalls are explained. Similar to their distributed computing descriptions necessitate, data parallel partition the information set across the array of firewalls, while function parallel distributes the work set across the array of firewalls. The data parallel technique is a scalable substitute to a single firewall that permits for better throughput potentials. Function parallel techniques can diminish the dispensation time necessary on any firewall node yielding enhanced presentation. In addition, unlike data parallel designs, the proposed function parallel architecture can offer stateful assessments. This proposal shows that function parallel designs are scalable solution that can offer better performance and more facilities than other designs. Parallel Firewall Architecture: Function Parallel Firewall [W. Fulp and Ryan J] consists of multiple firewalls coupled in parallel and a gatedevice, as shown in figure. Every firewall in the system outfits a local strategy, where incoming packets are disseminated across the firewalls for processing (one packet is sent to one firewall), permitting different packets to be processed in parallel. Because every packet is processed by the policy, reliability is maintained. The common operation of the scheme can be described as follows. When a packet reaches to the function-parallel system it is promoted to all the firewall and the gate. Each firewall processes the packet with its local policy, as well as any state information. The firewall then signals the gate representing either no match was found, or offers the rule number and action if a match was found. As local policies are a division of the original, a no-matchis a suitable answer and is necessary for the function-parallel design. The gate stores the outcomes and establishes the final action to achieve on the packet using the Firewall rule. Parallel Firewall System Components A function parallel system consists of a collection of firewall nodes. Packets are replicated to all firewall nodes as they go into the system. Policies must be disseminated across the system such that they specify an accept set identical to the original accept set and no local policys accept set can overlap another local policys accept set. The received packets are then combined into one stream to arrive at the destination. A control plane is also essential to permit common system management. Firewall Nodes The firewall nodes contain a network interface card for every network input and control plane. This design implements the firewall nodes as PCs running the Linux operating system with a kernel that supports iptables. It must be stated that iptables was selected for an profitable feature of provisional rule dispensation. By default there are built-in sets of policies called chains divided by whether they hold traffic bound for procedures pay attention on local input devices, proposed for routing throughout the system to another network or outbound and supplied from a local procedure. In addition iptables has support for user defined chains. The user defined chains can be called if a packet matches a rule in a sequence. Packet Duplicator Packet Duplicator is essential on all links which will input traffic into the system. In Ethernet networks packet duplication is easily achieved with a network hub because any packets arriving on a hub port are copied to all other hub ports. But, in high speed networks hub technology is not presented. The only available devices in high speed networks to attain duplication are network taps. These devices are used for duplicating network traffic, usually used in intrusion detection systems that necessitate network monitoring. Control Plane In a single firewall system, protected customer communication can be offered through the prerequisite of physical existence. To generate a protected technique of management, communication to the collection of firewall nodes can be quarantined on a separate control plane. In the simplest form this entails a separate subnet which all firewall nodes survive on. Component Integration Joining these components into a functional design can be cut down into two network representations. The first utilizes simply one packet duplicator and can simply offer protection for traffic from one source. The second topology allows two networks to communicate bi-directionally through the system. One-Directional System This technique only thinks about packets traveling in one direction; for example, only packets are moving from source to destination. The collection of firewall nodes use the same IP address and MAC address and all will take the incoming network interface card in immoral mode. All but one firewall node will allow existing networking equipment outside of the system to cooperate with no alterations. The firewall node which does respond to user requirements can also be permitted to respond to ICMP ping requests in order to formulate the system additional compatible. For the outgoing network interface cards, any IP or MAC can be used as long as it permits communication with the destination. Bi-directional System The Bi-directional system considers packets moving in both directions; for example, packets traveling from source to destination and then back to source. Set

History of Perfume and Fragrances Essay examples -- Hygiene Smell Essa

History of Perfume and Fragrances The history of perfume is a reflection of humanity: a means of exchange, a protection against disease, a potion with divine virtues, a gallant message, which reflects society, perceptibly communicating its sense of commerce and medicine, of the sacred and the sensual. The word "perfume" comes from the Latin per fume "through smoke". This refers to the original use of fragrances - the burning of incense and herbs as a religious offering. Perfume is made up of denatured ethyl alcohol and essential oils. The different names refer to the percentage of essential oils, and thus the strength of the scent. Perfume: 22% of essential oils. Eau de Parfum: 15 - 22% Eau de Toilette: 8 - 15% Eau de Cologne: 4% Ancient Time During the civilizations of antiquity, perfume was presented as an offering to the gods. It was believed to sublimate the body and make it more god-like. 10th Century BC: The Medes, ancestors of today’s Kurds are generally given credit for the invention and widespread use of perfumes, presumably to hide certain smells originating from overeating and failure to observe what are now common hygienic practices. 1580-1085 BC: The Egyptians create perfumes for daily consumer use and ultimately, use in religious ceremonies. Egyptian women used perfumed creams and oils as toiletries, cosmetics and aids to lovemaking. Queen Cleopatra was reported to use opiates and perfumes to seduce her many lovers and she may be the first to invent pomades from bear grease. Perfumes, especially those developed from resins, were originally used to appease the gods but in time they became more important in the embalming process for chemical reasons. Materials with drying agents like asphal... ...n Klein's, Yves St Laurent’s, and Nina Ricci's. Conclusion In the end, history of perfume shows how great human in developing what we call fashion. From all those history we know that there are a lot of perfume usages, like medicine, surgeon, etc. People developed not only the fragrances, but also the bottles. They also invented a lot of way to obtain the fragrances, like distilling oil from the petals of roses. After all, perfume is part of human history, without it our live is not complete.

Bottled Water in Australia

Bling h2o is a high end or â€Å"Super Luxury† bottled water product created by Kevin G Boyd a Hollywood producer / designer. Bling h2o costs from $US35. 00 to $US2,600. 00 per bottle and the water is bottled into glass bottles studded with Swarovski crystals. Bling has been featured on MTV music awards and The Emmys and on it’s website refers to itself as the Rolls Royce of bottled water. To identify the potential consumers in Australia we need to look at the target market and market segments bling are looking to fulfill. The premium status, and pricing, that bling put on their product would narrow the geographic segment to the economic centers of Australia, which Sydney, Melbourne and Brisbane. A geographic segmentation is identifying and analysing the location that a company is looking to move into. In Australia a potential geographic profile would start at the state level, then move into cities, then if necessary a municipal level to identify potential consumer (Kotler, P. , Adam, S. , Denize, S. , Armstrong, G. 2009), The demographic make-up of a potential market is made up of the age group, income, occupation, gender, race, education and religion. Demographic segmentation is a popular form of analysis and very important part of identifying the size and methods of communicating with a target market. (Kotler et al, 2009) After reviewing the media on bling and the website the demographic profile for bling would be 20 – 35 year old age bracket with a high level of income. This is supported by bling’s involvement with MTV, The Emmy's and the price of their product. The psychographic and behavioural segmentation bling would be looking at is a benefits viewpoint (Kotler et al, 2009). The benefits class is the benefits the user perceives to obtaining by using the product. The benefits from bling h2o are that of social status and class by drinking bling users would be setting themselves apart. From the marketing segmentation identified bling would be looking at a young high income earners who place a high importance on their external image. Along with targeting the these individuals, 5 star hotels and up market nightclubs would also be consumers of these products due the overlapping target market and perceived image they are looking to convey. This is identified by bling themselves on their ebsite where Boyd had the idea whilst observing celebrities and how each of them treated the bottled water they drunk In 2004 – 2005 Australians consumed about 550 million litres of bottled water, with worldwide consumption growing 57% from 1999 to 154 billion litres. (Munro 2006). The main industry body in Australia is the ABWI which was established 10 years ago and clai ms its objectives are to promote awareness and use of bottled water, and to ensure that consumers have safe good tasting water. The ABWI boasts member such as Coca- Cola Amatil Ltd and Schweppes Australia ttp://www. bottledwater. org. au/scripts/cgiip. exe/WService=ASP0003/ccms. r? Roxy=0x0002f062=10007 Bottled water is being looked at as a serious environmental issue. The main packaging for bottled water is plastic, which is made from fossil fuels and Australia uses 314,000 barrels of oil in bottling water each year (Koutsoukis, 2007) Although the plastic bottled water comes in is recyclable, Australians are only recycling around 35% of the bottled water they purchases, 55% goes to landfill which accounts for 70,000 tonnes of plastic waste. Koutsoukis, 2007) (Munro 2006). It is been seen as such an environmental issue that Bundanoon, a small town in NSW, has banned the sale of bottled water in its stores when a company was looking to extract water from their underground reservoir, and claims to be the first town in the world to enact such a policy. A review of social media surrounding bling h2o a large percentage of blogs condemned bling for being over priced and had concerns about water being sold at such a premium when much of the world is without clean water. An internet blog by Sassisam title Bling H2O – Ego in a bottle. Sassi Sam points out that she consumes 4 bottles of water a day and that would equate to $US980 per week just for water. Sassi Sam concluded that she would consider buying from bling if they supported charities that focused on supplying clean water to those who don’t have access to it. Bling was featured on the site BoingBoing and points out that people who buy this must be fools. The interactive comments section of BoingBoing raised the issues of the importance of social status and that is reaching ridicules levels. BoingBoing was the only website that brought up the issue of socially responsible marketing by user Cameron Barrett. If the author of this article was the brand manager of bling h20 they would be associating themselves with one of the many charitable organisations that are helping provided clean drinking water. An organisation like charity water is able to provide a person with clean drinking water for $1 a year. This small cost compared to the premium charge would quell the concerns over the ethics of the company and leave the image issue with those who buy it. ttp://www. theage. com. au/news/national/bottled-water-the-new-ecodisaster/2006/02/25/ 1140670303250. html http://www. theage. com. au/articles/2007/08/18/1186857841959. html? page=fullpage#contentSwap1 http://news. bbc. co. uk/2/hi/asia-pacific/8141569. stm http://www. bottledwater. org. au/scripts/cgiip. exe/WService=ASP0003/ccms. r?

Meeting of minds Essay

In what ways does this scene represent 2 characters crossing boundaries and understanding each other – a meeting of minds?  The scene automatically has a sense of irony, as both Yolland and Maire both cannot understand a word each other is saying, this means communication was needed to be made in an alternate way, these ways are through the use of identifiable feelings and emotions, as well as paralanguage to indicate the feelings and emotions that the character is trying to express. Throughout their conversation, it would seem unlikely to a person who has just picked up the book that Yolland and Maire do not speak the same language, and therefore cannot fathom what each other is trying to say. This is due to the similarities of speech between the two of them; they always seem to have a vague understanding about what the other person is trying to say. An indication of this is where Maire says, † The grass must be wet. My feet are soaking.† straight after Yolland points out, † The grass must be wet your feet are soaking.† It is clear to see the similarities in their speech, although the context is just flipped around, but apart from that it is almost identical. Emphasising this collision, linguistically speaking, is the stage directions, expressing the characters body movement. The way they seem very immature when they realise they are holding hands, then immediately disengage and move apart. Another way that they can be seen as immature is through the basic communication, such as pointing. Knowing that the other person cannot understand what they are saying might be a factor in the characters lexis, especially regarding Yolland where he says â€Å"I’ve been watching you night and day for the past†¦Ã¢â‚¬  because if Yolland was to say this to Maire and she understood it, she could take it two very different ways, and decide that in fact Yolland is a bit weird. Without the aid of a similar language the characters find another way to communicate, which involves Maire saying English words, which she knows, and Yolland encouraging her, â€Å"Yes-yes? Go on- go on- say anything at all- I love the sound of your speech.† This shows although they cannot understand each other Yolland is fixated by Maire, and there is this chemistry, a bond between them, which they both know, are there but just can’t explain it to each other. The communication between the two of them become so intense that Yolland starts reeling of whole sentences, without realising that Maire does not have a clue what he is on about, she just stares at him unknowingly and wondering. It becomes clear that they need some common ground to try to relate with each other this occurs, when Yolland starts saying Irish place names, Maire reciprocates and this carries on as though they are flirting, which leads them back to the way they were, when they ran together, as once again they were holding hands, at this point they exchange their raw feelings without the satisfaction of being understood, they hold each other and tremble in one another’s arms, the lexis leading up to the kiss is very heated, there is a mutual understanding of the word ‘always’ I believe this to be significant as this is one of the final words before they kiss it just shows the compassion they hold for each other. Unquestionably above everything the connection is a meeting of minds as the only way of really communicating was through paralanguage, and the fact that they are very similar people, with similar thoughts and feelings, about the way they act, the way they speak, and the way they feel for each other. In a way their relationship could be seen as an example to be followed, as if individual Irish and English people can get along and fall in love, what’s to say England and Ireland should not at least be able to tolerate each other. Yolland and Maire, by not understanding verbally, will have an extremely deep understanding of each other mind, in turn this may lead to a significantly compassionate relationship, or just a passing phase, however I believe there is a meeting of minds, and the kiss only emphasises the coming together of these two foreign bodies into one.

The Yalta Conference essays

The Yalta Conference essays In February 1945, Nazi armies were quickly beaten back towards Berlin by armies of the Soviet Union. British and American forces were preparing to invade Germany. Unconditional surrender could be expected from Germany in a matter of weeks. Also, in the Pacific War, American forces moved steadily from island to island towards a final invasion of the Japanese home islands. The possibility of using an atomic bomb to end the war was unknown to military experts and world leaders. With the defeat of Germany and Japan a certainty, the leaders of the Big Three Allied Powers, Prime Minister Winston Churchill of Great Britain, Communist Party Secretary Joseph Stalin of the Soviet Union, and President Franklin Delano Roosevelt of the United States, met to plan and discuss the postwar world. The meeting was held at Livadia Palace at Yalta on the Crimean Peninsula of the Black Sea from February 4 to February 11, 1945, and was called the Yalta Conference. Was the Yalta Conference a success for the United States and Great Britain? One possibility is that a wily Joseph Stalin took advantage of an ailing Roosevelt to get many concessions in return for few on his part. It may also be argued that the agreements reached were mostly harmless and benefited none of the Big Three. Along this same notion, it can be argued too that conflicting aims and conflicting personalities inevitably led to compromises that failed to satisfy any of the leaders. The correct answer to the question is actually that the Yalta Conference was a success for the United States and Great Britain because they benefited most. That is to say that even though some significant concessions were made to Stalin by Churchill and Roosevelt, Stalin's concessions were even more significant. If it appears, in hindsight, that the Soviets came out ahead, it is because Stalin went back on his word, not because of concessions to him. Discussions at Yalta opened on the topic of the f...

Characterization of Flat Characters essays

Characterization of Flat Characters essays Characterization of Octavia In Ernest J. Gaines, The Sky is Gray, is a story of a woman during World War II, who is faced with the challenges of raising and providing for her family financially in the absent of her husband because of the war. Her realistic attitude about her role as head of the family in the absent of her husband has changed her dramatically. The happy and cheerful social person Octavia once was is transformed into an abusive, demanding, but compassionate woman. Octavia, the mother who assumes the role as head of the family abusive behavior is describe by James, her son, in which his description fosters that of a tuff, no nonsense kind of woman. Her abusiveness can be seen in many instances, for example, the constant whipping of Ty, another one of her sons, because of his fear of ghosts (4). Another prime example and show of Octavias abusive trait as depicted by James, She slapped me again (67), and She started hitting me cross the back. I went down on the ground, crying (76). Not only is Octavia abusive, but also sadistic, as thought she enjoys inflicting pain, her pain, in which she suffers internally, but is blinded by her idealism of turning her boys into men. Assuming the role as head of house is stressful for any mother who is use to a man in the house. Octavia becomes quite demanding in this new role of hers. Get him out of there, she repeated over and over again, Get him, Octavia demand James, in the fetching and the killing of redbirds for the evening meal (paragraph 54-80). I side with Octavia in some respect, however, her demand for James to kill could have a ripple effect much later in life if not now, and damage the boys, Ty and James for life. Like most mothers, Octavia is compassionate in many respects. The moment she learns of Jamess situa ...

A Look at the Biological Variances of Different Primate Groups

A Look at the Biological Variances of Different Primate Groups The evolution of primates arose from the ancestors who used to live in tropical forests. Thus the characteristics of species diversity regarding non-human primates represent their adaptions to life in this uncertain environment (Kinzey, 2012). However, the species of most primates remains partially arboreal except for the human beings, who inhabit almost every part of the continent, whereas most non-human primates live in Africa and Asia’s tropical regions (Abee, 2012). Non-human primates exhibit a wide range of characteristics. For instance, some primates such as the baboons and the great apes are predominantly terrestrial rather than arboreal. However, all species diversity regarding non-human primate possess adaptations for climbing trees. Some of the locomotive techniques exhibited by the non-human primates include knuckle-walking and swinging from one branch of the tree to the other (Kinzey, 2012). Additionally, the non-human primates are usually characterized by exceptional intelligence and better reliance on stereoscopic vision as a result of their dominant sensory system. However, exceptional intelligence and better reliance on stereoscopic traits are more advanced on great apes and monkeys and less notable in lemurs and the lorises (Abee, 2012). The three-color visual abilities and the sexuality dimorphic such as the body mass, the size of the canine tooth and the coloration also differs among species diversity with regards to non-human primates. Thus, primates with greater sizes have a slower rate of development to reach maturity and a longer lifespan, unlike those with smaller weights (Kinzey, 2012). Primates range in different sizes with regards to the particular species classification they belong in. For instance, the weight of the Madame Bertha’s mouse Lemur is about 30 grams in contrast to over 440lbs weight of the Eastern Gorillas (Platt Ghazanfar, 2010).Therefore, according to the fossil evidence, the genus species of Teilhardina was the earliest known trues non-human primates dated to over 55.8 million years old (Kinzey, 2012). Traditionally, the order of the non-human primates was categorized into two major groupings which include the prosimians and the anthropoids. The character traits of the prosimians are similar to those of the earliest primates such as the lorisoids, tarsiers and the Madagascar (Platt Ghazanfar, 2010). The category groupings of the anthropoids include the monkeys, apes and the hominins. However, the recent taxonomists have preferred to split the species diversity regarding non-human primates further into Strepsirrhini and the suborder Haplorhini. Strepsirrhini is the wet-nosed primates, and they majorly consist of the non-tarsier prosimians. On the other hand, suborder Haplorhini represents the dry-nosed primates such as simians and tarsiers. Additionally, simians are further classified into two groups which include the catarrhine and the platyrrhine (Tomasello Call, 2013). Catarrhine are the narrow-nosed monkeys and apes of tropical regions of Africa and the Southeast parts of Asia which includes the baboons, macaques, and gibbons. On the contrary, platyrrhine is the flat-nosed simians of the South and the Middle Americas tropical and subtropical regions. The platyrrhine consists of new world monkeys such as the howler, squirrel monkeys and the capuchin (Platt Ghazanfar, 2010). The classification of primate lineage is divided into six significant superfamilies which include the Lemuroidea, Lorisoidia, and Tarsioidea. Additionally, the Ceboidea, Cercopithecoidea, and Hominoidea are among the six significant superfamilies of the primate lineage (Tomasello Call, 2013). The family of Lemuroidea is characterized by closely spaced projecting canines and a claw on their second toes as opposed to the nail. Therefore, Lemuroidea consists of both woolly and sportive lemurs and the allies (Tomasello Call, 2013). Contrary to Lemuroidea, Lorisoidea primates are characterized very long legs and nails and large feet, hands, ears, and eyes. Most primates in Lorisoidea lineage are quadrupeds, and thus they include bush babies, lorises, and pottos (Kinzey, 2012). On the other hand, Tarsioidea is characterized leaping and clinging to vertical branches of trees and their nocturnal activity patterns. Tarsioidea primates consist of Tarsius eocaenus and the Hesperotarsius thailandicus (Tomasello Call, 2013). Cercopithecoidea, Ceboidea and the Hominoidea primates lived over 55 million years ago and consequently forms a single clade on the evolutionary stages of species diversity regarding non-human primates. Ceboidea is characterized by round and forward-facing nostrils and the upper and lower premolars on each side such as the squirrel and capuchin monkeys (Platt Ghazanfar, 2010). On the contrary, Cercopithecoidea includes the baboons and macaques which exhibits unique molar shapes and bilophodont. Finally, Hominoidea is mostly omnivorous primates, and thus have an excellent adaptation for chewing and digesting. Hominoidea primates consist of gorillas, chimpanzees, and orangutans (Tomasello Call, 2013). Although pro-simians and great apes are frequently used interchangeably, theyre not the same according to the scientific point of view. Pro-simians and Great apes are among the non-human primates that have evolved differently, with each exhibiting different physical and mental characteristics. However, they somewhat share similar traits, such as they are both from the same Animalia kingdom, mammal class and order of primates. Additionally, they all come from the same Haplorhini suborder and the simiiformes suborder (Abee, 2012). In as much as the pro-simians and the great apes shares similar traits, they also have different characteristics. Although pro-simians can communicate with each other, great apes possess a more developed and sophisticated cognitive and language skills. They cannot speak like human beings. However, they can use sign language skills and other bodily gestures to communicate with each other effectively (Platt Ghazanfar, 2010). Also, based on the evolutionary and genetic terms, the species of great apes are much more close to human beings than the pro-simians. Great apes are more intelligent and can manage to exhibit human-like behavior as opposed to the latter (Platt Ghazanfar, 2010). Pro-simians and great apes differ on the lifespan perspective. Unlike, great apes which can live up to 60 years, pro-simians can only live up to 30 years. The body structure of great apes is also different from that of the Pro-simians. Contrary to great apes, pro-simians are characterized by large eyes and a more significant sensitivity of nocturnal vision, a strong sense of smell, complex tactile hairs and the large and independently movable ears (Kinzey, 2012). Although monkeys exhibit the same external physical appearance, a close scrutiny on their physical appearance makes it easier to distinguish between the old and the new world monkeys. Old world monkeys are catarrhine, and thus narrow-nosed in contrast to the new world monkeys which are platyrrhine, and hence flat-nosed (Kinzey, 2012). Also, the nostrils of the old world monkeys are closer together and open downward, whereas the nostrils of the latter are far apart from each other and open sideways (Kinzey, 2012). Additionally, there is a significant variance in size between the old world and the new world monkeys. Contrary to the new world monkeys which exhibits a smaller and medium-sized weights, old world monkeys are mostly large sized primates, and thus have greater weights (Kinzey, 2012). Unlike, the new world monkeys who are mainly tree dwellers, the latter have a wide and varied habitat such as the deserts and the rainforests. In conclusion, I believe diversity exists between the species as a result of genetic variation which make up a particular species. Genetic diversity enables species which shares the same genetic characteristics to adapt to the changing environments (Abee, 2012). Thus, when the habitat changes, the species can be able to adapt to survive. The ability of the species to adopt to the changing environmental conditions determines their ability to cope with various challenges regarding the change of the environment. Therefore, genetic diversity is essential as it is vital in determining the survival and survival and adaptability of a particular species (Kinzey, 2012).

8.6 case study - Coursework Example In the perspective of the second meaning, organizations promote corporate ethics so as to define a set of corporate values, to meet consumer expectations and employee demands, and to deal with economic pressures effectively (p.620). When it comes to IT practices, the first definition (meaning) implies that firms must develop improved IT policies and procedures to operate in well compliance with federal laws and regulations. From the same viewpoint, the second definition implies that organizations need to maintain well established IT practices to ensure that consumers enjoy the benefits of convenient shopping and consumers’ tastes, and specifications are adequately addressed. The firm’s economic environment can have a great influence on these practices. Companies have more choices when economic conditions are favorable but choices may have to be limited under the situations of economic downturns. 2. The advancements in IT greatly benefit corporate enterprises to address ethical issues effectively, and to take advantages of emerging opportunities with regard to corporate governance. The case study tells that IT can contribute significantly to corporate strategy. CIOs can identify the misuses of those IT capabilities, and they will be also able to flag those issues timely and thereby prevent the firm from becoming exposed to scandals. The case described about the business fraud committed by marketing workers at a large telephone company can be cited as a good example. The company executives had identified the fraud before the marketing department actually executed it. Then they developed a comprehensive IT system to monitor the use and prevent the unauthorized access to such sensitive information in future. Similarly, Intel’s IT system helps the company meet its legal and regulatory requirements in addition to enhancing its own corporate values and ethical principles (p p.620-621). 3. In my personal view, organizations should pursue high ethical standards in

Models of art ( anthropology ) - Essay Example This period from 25 to 220 CE differed from its earlier namesake (Pirazzoli-T'Serstevens 34). As regards the chronology of the Han ceramics, the dates furnished by two pieces are of primary importance, the one, 133 B.C., found by Bushell on a vase of the Dana collection; and the other, 52 B.C., on a jug (Pirazzoli-T'Serstevens 40). There is another vase bearing the year-period Shn chek, i.e., 61-57 B.C.; but the reading of this inscription is still obscure. On the basis of these data, archeologists presume that this pottery originated in the second and first centuries before our era, although it may well be that some pieces belong to the first century A.D., which may be considered as the terminus ad quem. From internal evidence it is possible to fix the date of the type of the hill-censer in the first part of the first century B.C (Pirazzoli-T'Serstevens 42). The widest spectrum of surviving types is found in craft goods of daily use such as ceramics and textiles. Ceramics can be classified according to many different features. Technical criteria, including firing temperatur e and body types; style features, including glaze, decor, and favored shapes; geography or kiln sites; and the issues of taste, use, and markets discussed here are all important. Ceramic wares range from middle-class types to refined luxury wares commissioned by the imperial household and limited to that environment (Spirit of Han 12). Vessels occupied a special position during the Han dynasty as the main tool of cooking and baking. A typical bowl-shaped vessel of Han pottery with oblique handle terminating in an animal's head, much resembling the cooking-vessel found on the stove (Cooper 38). To obtain a clear understanding of this type, archeologists discuss two related bronze types of the same period. By the term chiao tou, two kinds of copper or bronze vessels are understood: (1) a vessel provided with three feet and a handle, and serving to cook food in; (2) a cookingpan, used in camps by soldiers for preparing their food in by day, and for striking the watch by night. The latter vessel is also called tiao tou. To avoid confusion, critics restricted the term chiao tou to the tripod cooking-vessel, and tiao tou to the cooking-pan without feet (Cooper 36). The example selected for analysis is the chiao tou made of bronze (See Appendix, Picture 1). The total height up to the head of the animal is 24.3 cm; up to the rim of the vessel, 16 cm; the height of the feet being 11.2 cm. The diameter of the mouth is 19.8 cm; the depth of the vessel, 7.8 cm. The copper material is covered with black, reddish, and green spots. According to the verbal explanation of a Chinese archologist at Hsi an, the animal forming the handle is "the scaly dragon" and the vessel was used like a ladle, for scooping water, the long neck of the chiao serving as handle (Cooper 37). The animal's neck and feet are curved in a different manner. The neck is joined to the vessel by means of two small parallel pieces, but the whole is made in one cast. The mouth of the monster is wide open. The feet are rounded out, and the lower ends are evidently worked into hoofs. Around the body of the vessel are four parallel raised lines, the so-called "girdle- ornament." Through the

Pioneer Financial Group is facing a conflict of interest of some shareholders, side deals done by employees, and corruption. Establishing an ethical business culture is one way of improving the corporate governance. Pioneer Financial Group should have ethical codes that promote ethical behavior. This guides employees in cases where ethical course of action is not clearly known. The codes help the company to communicate their expectations to employees, communities, government, and other stakeholders. The codes do promote market efficiency, build public trust, enhance business reputation, raising awareness on the societal needs, and help the company reinforce and acquaint new employees with their values and culture. Pioneer Financial Group have put in place training programs regarding ethics in the company that are designed to offer real solutions to those employees under ethical dilemma.
