The Concept of Business Strategy Essay Example | Topics and Well Written Essays - 750 words

The Concept of Business Strategy - Essay Example The arrangement of the five forces varies across different industries. For instance, in the commercial airline industry, stiff competition exists between Boeing and Airbus, the power of suppliers, threat of entry and the threat of substitutes are weak while the power of suppliers is strong. In the movie theatre sector, the increase of entertainment and the influence of distributors and movie producers and inputs are significant. The first component in the tool refers to supplier power and refers to the ease of suppliers to lead to changes in prices. This is influenced by the number of suppliers in at each point of production, the cost of switching between suppliers, the power they have over companies and the uniqueness of the product or service. The less the supplier options that are present in an industry, the more power the consumers have. The second aspect of the Porter Five-tool is buyer power and it relates to how easy it is for consumers to lead to a reduction in prices. This i s influenced by the number of buyers, the cost of their decision to switch to other products and services and the value of each customer to the organization. Companies that deal with a relative number of powerful buyers, they have a huge impact on them.The third aspect is competitive rivalry and this relates to the number and ability of the competitors. If a company has a high number of competitors that offer better products and services then, the company has minimal power over the situation.

Propaganda Assignment Example | Topics and Well Written Essays - 1000 words

Propaganda - Assignment Example Posters have been used as an informative or propaganda means for a very long time. They have been advancing with the advancement in technology. This advancement has been majorly structural and appearance in form of colour and shape but the purpose remains informational conveyance. (b) Introduction: This paper is going to give the full meaning of the term propaganda and its importance in the society. The term propaganda refers to the different means used by media and other informative systems in informing about different emerging issues. These issues might be pertaining to fields such as politics, education, economic development, agricultural field, industrial development, environmental conservation, energy conservation and other lively related fields. The use of propaganda started a long time ago but has been undergoing evolution as technology advances and modernity takes over. In this section, the paper would be giving samples of posters developed with a purpose of informing people about six main fields in human life. This paper would then give a brief explanation as to how these types of posters have undergone structural change as they retain their purpose and theme in human life. Therefore this paper would look at five different posters and the historical context under which each of these posters was created. It would further look at how politics and culture of people has influenced them. In addition to that, the ways in which each poster is set to meet its intended purpose as based on the targeted audience. (c) Different types of posters and the message they convey to the society (a) The poster above is a poster on fighting pollution in the society. It is a hand designed poster as from its look. It is a type of poster that is linked with the 1920s. During this time, the world had undergone less advancement in technological field. When this poster is presented in a new form of the present generation where technology is exclusively used, it would be structura lly improved. This structural improvement would be from a hand drawing into a photo taken picture with at least a digital camera recorder. If not in form of a photo, it would take the form of mobile pictures where human being should be associated in the picture. Nowadays, if a poster on fighting pollution should be produced, then it should show an illustration of the effects of pollution on the environment. Culturally, people who are the main preservers of the environment from pollution should also be included. This is the political and cultural effects that politics would have on the poster above. The main reason is to make clear and sure that the theme of the poster is well conveyed to the society which is the intended audience. (b) The above poster is a poster created in the new generation of 21 century with fine artists showing out their talent. It is a politics related politics and that is a reason why the term â€Å"HOPE† is included to encourage people on choosing the person on the poster during election (Stromquist, 2008). Therefore, despite the fact that the poster was meant to be coloured, the whitish colour was intentionally put in to show peace and purity. In the new generation where most of the youths are unemployed despite their good talent and thus they require employment opportunities. Therefore, the

Efficient Streaming Protocol for Transmitting Video Files

Efficient Streaming Protocol for Transmitting Video Files Chapter one Introduction Chapter One Introduction 1.1 Motivation Information in computer science might be represented in multiple forms. In the beginning the first used forms of information were text and images, after the huge increase of using computers and internet another type of information appears, it is the hyper text which is the combination of text and images. Hyper text is text pages that connected by hyper links (hyper link provide non linear access to the text pages no need to view all the pages sequentially to access a specific page) and then new forms are used like Audio and motion pictures or videos, nowadays a combination of these representations as well as the traditional forms (text and images) is called multimedia [LIZ04]. Multimediais a data type may contain multiple types of information like: audio, video, and animation in addition to traditional media (text, graphics, drawings and images), Digital multimedia is a data type represented by series of bits and manipulated by some multimedia applications and stored on some storage units like on CD or DVD or in multimedia servers. Digital multimedia can be interactive (non linear access) that can be manipulated with computer programs (create, edit, transfer), or non interactive (linear access) where the viewer is unable to control the multimedia like the presentation of movie in the cinema [LIZ04]. Hypermedia is a collection of many types of information like text, images even videos in one website or more that are connected together by some hyper links that provide non linear access to the media like encyclopedia which user can jump from article to the other or jump to the next mark in DVD. The figure 1.1 below shows the structure of Hypermedia. Figure 1.1 Hypermedia Multimedia applications are a computer based programs that are designed to manipulate multimedia data with different sources like text, graphics, audio and video [NIE07]. Multimedia applications can be found in many areas such as: Education, nowadays computer based training applications that designed to simulate the scientific experiments by creating the reactions environment and show the hypothetical results that should be produced from the row materials that will react in the reaction environment, these applications are safer for students from some experiments in real world as well they use some visual effects to explain some phenomenon like physical, chemical and geographic learning applications. Advertising, multimedia applications can be found in advertising and journalism like the advertising of products and places like restaurants and companies, in journalism nowadays electronic copies of magazines and journals. Entertainment, in this field multimedia is used to design video games and visual effects of games and movies, interactive multimedia is used heavily in video games that the user participates alone or with others on the same computer or over the internet not just sit and watch. Industrial sector, multimedia is used as a way to help present information to shareholders, superiors and coworkers. Multimedia is also helpful for providing employee training, advertising and selling products all over the world via virtually unlimited web-based technology. Mathematical  and  scientific research, multimedia is mainly used for modeling and simulation. For example, a  scientist  can look at a  molecular model  of a particular substance and manipulate it to arrive at a new substance. Representative research can be found in journals such as the  Journal of Multimedia, in engineering multimedia applications now used to design buildings and machines before implementing them in real world [LIZ04]. Since multimedia represents some motion captured and stored on some remote place there must be some kind of delivery mechanism to transfer multimedia files from its source (producer) to the destination (consumer) [LIZ04]. Multimedia delivery can be divided into two categories offline and online delivery, offline delivery means transferring multimedia, without using internet, by using removable storage medium like CD-ROM to the hard disk on one station, multimedia was spread widely after the increase using of CD’s DVD’s and now Blue ray which are large storage media can hold the large size of multimedia files, online delivery (also called Streaming) uses the internet for transferring the multimedia from the producer which is usually a server with bulky storage to the consumer which is the client who can be any terminal mobile phone, personal computer or television and takes into consideration the statues of the network the client and server are connected to. Online delivery transmits video files for events happened at the same time like video conferences, football games or video calls; or already processed and stored videos like video clips and movie trailers, online delivery multimedia and websites should be written in an efficient way to transmit or deliver the multimedia files and they are able to be read by the client, also there must be enough resources for the network and the client (which are available bandwidth, network throughput, congestion, and for the client the available buffer and client’s device speed, etc..) in order to transmit the multimedia file efficiently and the client has a successful experience [NIE07][LIZ04]. The adaptive streaming is the process of transmitting videos from the server to the client over internet in an efficient way depending on the network and client’s statues; to deliver videos faster and fewer pauses different qualities are saved to the same video and the server switches between these qualities according to the network and client’s statues. In this thesis, a proposed protocol for streaming videos in adaptive way is introduced; the protocol has two sides the server or the sending parity which is responsible of transmitting the video files to the client in an adaptive way and the receiving party known as the client who receives the videos and displays them on his screen, adaptive means taking into consideration the statues of network like the available bandwidth in order to transmit the video file to the client smoothly, the processing of the video files is done on line, in other words the video frames are processed during the transmission according to the available bandwidth measured at the moment, dislike the used technologies nowadays which they save more than one copy of the video file with different bitrates and transmit the proper bitrate version of the video to the client according to the available bandwidth. Literature Review In this section reviews to some related work for this thesis about the dynamic video streaming over the internet â€Å"A Buffer-Driven Approach to Adaptively Stream Stored Video over Internet†, by Dejian Ye [YED02], In dynamic video streaming technique many parameters can affect the streaming operation of video from a server to client one of these parameters is the buffer size of the sending and receiving parts, authors focused on the server and client buffer size and according to their statues server decide the quality of transmitted video, the buffer size and amount of available buffer size in the sender and receiver sides decide the quality of the transmitted video from the server to the client. â€Å"ENet Dynamic QoS Controller for Video Streaming Application†, by Qingyang Wang [WAN10], the popularity of video on demand and streaming over the internet increased and the limitations between the server and the client that may appear during streaming like supporting data type or bandwidth or computer speed and throughput and how to maintain a good QOS the authors design Enet which is a tool added to the server. Enet is a simple Fuzzy System used to switch between multiple bit rate versions of video, it picks the most appropriate bit rate to the client’s properties, this method takes a large storage space since it stores multiple versions of video with different bit rate for each video copy. â€Å"Adaptation Algorithm for Adaptive Streaming over HTTP†, by Konstantin Miller [MIL12]. Internet videos (live or on demand) take a large amount of internet traffic, in this paper authors build an algorithm for the client side which tries to improve the delivery of video to the client by making client selects the appropriate bit rate depending on the client and network conditions like bandwidth available buffer and network throughput. They integrated the algorithm with a prototype implementation of a streaming client based on the MPEG DASH (Dynamic Adaptive Streaming over HTTP) standard which divide the video file into segments and each segment is saved in a number of different bit rates and client take the responsibility of selecting the most appropriate bit rate depending on the clients and network state. The design of the algorithm download the video file as segments one after the other and it uses one buffer that results client cannot receive the segment N unless it com plete receiving segment N-1. â€Å"Confused, Timid, and Unstable: Picking a Video Streaming Rate is Hard†, by Te-Yuan Huang [HUN12], Hulu, Vudu and Net Flux are three video streaming service providers that provide videos with high quality to the users with some fee. Videos provided by these services are divided to chunks with multiple bit rates for each chunk (when bit rate is slow chunk size is small and high bit rate the chunk size is big) and server switches between these chunks with different bit rates according to the available bandwidth. The problem is when requesting a video and start watching it and after some time another video requested a downward spiral effect appears which is bit rate goes down to the lowest level despite there is enough bandwidth for higher bit rate. â€Å"USING SCALABLE VIDEO CODING FOR DYNAMIC ADAPTIVE TREAMING OVER HTTP IN MOBILE ENVIRONMENTS†, by Christopher Muller [MUL12], DASH is the approach that is used to transfer video over the internet in dynamic way to the user, it’s done by saving multiple copies of the video each copy with different bit rate and the server starts switching between these copies or bitrates according to client’s specifications. In this paper authors uses scalable video coding (SVC) instead of advanced video coding (AVC or H264) which provide more flexibility to the system with the available bandwidth and the buffer size, But if the client switches from one bit rate to the other (higher or lower) and he already requested a chunk before, this chunk will be canceled. The server will save multiple copies of video as a group of chunks. SVC experiment and code depend on windows so it’s not available to other operating systems. â€Å"OPTIMIZING HTTP-BASED ADAPTIVE VIDEO STREAMING FOR WIRELESS ACCESS NETWORKS† by Xiaoling Qiu [Qui 13], Authors in this paper propose new approach for dynamic streaming videos over HTTP; their approach measure the available bandwidth of the network and client’s CPU speed and old measurements into account to select the best video quality using an optimization algorithm. This method contains optimization algorithm to select quality of segments to be sent to the client, but this method suffer from high computation rate. Aim of thesis The aim of this thesis is to build an efficient streaming protocol for transmitting video files from the server to the client with accepted waiting time at the client side. The work in the thesis focuses on video files transmission to provide the accepted delivery time, videos usually are large size files this needs compression method to be used to reduce the video file size when the available bandwidth is below the required level for transmitting videos without compression, also this thesis takes into consideration the quality of the delivered video, the quality of the received video is maintained since the used compression technique in the proposed protocol is lossless technique so there is no loss in the transmitted video file quality at the client side. Another important side in video streaming technique is the buffer management; the proposed streaming protocol uses a variable size for the buffers at the server side and the client side. This approach guarantees the efficient delivery of the required video file without take more than the required memory space. The limitations that affect the proposed protocol execution are: The execution on the internet is hard because it needs to reserve domain in a server over the internet, so the proposed protocol implemented on Local Area Network. The bandwidth values are not real and they were generated randomly to simulate the change on the available bandwidth in real world but the limit of bandwidth was selected depending on used LAN defined bandwidth. Outlines of the thesis This thesis is organized in five chapters as follows: Chapter one: â€Å"Introduction† This chapter begins with explanation of the meaning of multimedia and its applications in real world and also contains a list of reviews works related to this work. Chapter two: â€Å"Theoretical Background† This chapter contains description of the main concepts of video file, video streaming, compression and quality. Chapter Three: â€Å"Video Streaming Protocol† This chapter contains the proposed streaming protocol between the server and the client that satisfy the aim of this thesis of delivering video from the server to the client with little or no pauses and with acceptable quality. Chapter Four: â€Å"Experimental Results† This chapter contains the results of the video streaming protocol introduced in the thesis. Chapter Five â€Å"Conclusion and Future work† This chapter contains the conclusions and the future work for the thesis. 1

Analysis of Raleghs Nature, that washed her hands in milk Essay

Analysis of Ralegh's "Nature, that washed her hands in milk" Nature, that washed her hands in milk† can be divided structurally into two halves; the first three stanzas constitute the first half, and the last three stanzas make up the second half. Each stanza in the first half corresponds to a stanza in the second half. The first stanza describes the temperament of Nature, who is, above all, creative. This first stanza of the first half corresponds to stanza four, the first stanza in the second half of the poem. Stanza four divulges the nature of Time, who, unlike Nature, is ultimately a destroyer. Time is introduced as the enemy of Nature, and Ralegh points out that not only does Nature â€Å"despise† Time, she has good reason for it (l. 19). Time humiliates her: he â€Å"rudely gives her love the lie,/Makes Hope a fool, and Sorrow wise† (20-21). The parallel between the temperaments of Nature and Time is continued in stanzas two and five. Stanza two describes the mistress that Nature makes for Love. This mistress, who is made of â€Å"snow and silk† instead of earth, has features that are easily broken (3). Each external feature is individually fragile: her eyes are made of light, which cannot even be touched, her breath is as delicate as a violet, and she has â€Å"lips of jelly† (7-8). Her demeanor is unreliable, as well; it is made â€Å"Only of wantonness and wit† (12). It is no surprise that all of the delicate beauty Nature creates in stanza two is destroyed by Time in stanza five. Time â€Å"dims, discolors, and destroys† the creation of Nature, feature by feature (25-26). Stanzas three and six complete the parallel. In the third stanza, the mistress is made, but in her is â€Å"a heart of stone† (15). Ralegh points out that her charm o... ...s known to outlast flesh once a body has died. Time spoils the insides of the mistress, as well; he â€Å"doth dull each lively wit,/And dries all wantonness with it† (29-30). The poet’s preservation of the order of creation and demolition helps to present Time as a methodical destructive force. Time is in no hurry to get rid of the mistress or beauty, but he certainly will perform his task to completion. Careful word choices and syntax aid Ralegh’s depiction of Time, as well. Reading â€Å"Nature, that washed her hands in milk† feels like a lesson and a story at the same time because the syntax is short and to the point. Each stanza ends with a rhyming couplet, giving a self-contained feeling to each phrase, which lends to the aphoristic feel of the poem. Both Ralegh’s plain style and his use of parallel structure serve as vehicles to convey the meaning of his poem.

Importance of Computer Network Service Levels

This paper explains the importance of the different service levels of computer networking such as availability, reliability, response time and throughput. It aims to literate the people managing the network to be aware of these different key areas so that they may always be reminded of their duties and responsibilities in securing the network. Network Computers Networked computers have been a part of every business both big and small. People invest their time, effort and money to make sure that communication and information is always available. Information Technology as a part of any organization is crucial to a business success making it one of the most budgeted departments of the organization. People who takes care of the network should know the importance of service to customers and co-employees regarding availability, reliability, response time and throughput. Availability Technology is made to serve the people in the shortest time possible. The network group should always make sure that the network, workstations and other technological resources that is operational through networks are all stable and in perfect condition. Monitoring should always be a part of the network group’s daily routine to ensure that all devices are working properly to avoid any downtime. Risk management should always be implemented and observed at all time. The group should be knowledgeable enough to sustain the network in all possible circumstances and emergencies like earthquake, sudden power failure and more. The IT group with the help of the management and customers should also have an understanding in the implementation of availabilities of the business network and other resources through proper endorsements and reporting to make sure that communications and transactions will not be hampered. Reliability The information and data gathered from computers and other resources are one of the most important tools for decision making in any business or organization thus making it one of the most sensitive to monitor as well. It is important that customers and employees trust the accuracy of the software or machines that they use. The network group’s job is to make sure that all data and information are well transferred to customers and employees everyday. LAN testing should always be a part of their daily routine to test the reliability of their network. Response Time Fast and accurate information and output is so important in this fast world. That is why the word downtime must not be in an IT group’s dictionary. Network performance must always be in its best. This can be assured through testing the network every now and then. The network group should also be knowledgeable enough to design the kind of network topology and know the tools that can be used in different kinds of work environment to ensure fast performance, resilience, scalability and flexibility of the network. Throughput Networking is at its best when they do their work as what they are expected. Processing speed is measured by users every time they work and throughput can be a kind of measurement to see if their device is doing its work well. For example, if a printer is expected to print 100 papers per hour but it seems that it’s only printing 65 papers, the time wasted in printing or downtime is a big factor for the performance of the users that may bring bad effect to their transaction as they go on. Network groups must not see this as a small problem because it may someday be an alerting one. They must have the time to check even the smallest details if they want to avoid larger problems that may come in the way. Conclusion Computer networking is one of the most challenging task that an IT or network group may have. It is the veins of success to any transaction. If the group who are responsible in making, designing and implementing networks are all knowledgeable and capable of maintaining and securing a network, then progress and good working environment will be at hand. It is best that the network group is knowledgeable in their field. However, all of the hard works of the IT group will not be successful if they do not have the support of their co-workers and the top management.

Isolation (Of Mice and Men) essays

Isolation (Of Mice and Men) essays Isolation is the term used when a being is confined to himself without any outside contact. In the story, Of Mice and Men, isolation was a major role forced upon Crooks and Curleys wife. Crooks is an old black man whom lives in a little hut beside the manure pile, and lives and sleeps by himself, with no contact besides orders. Curleys wife was isolated, simply because Curley didnt not trust her, and considered her to be a tart. These two characters have a lot in common as shown through this story. Crooks is a slave, an old black man whom is literate and tends to be crabby. He is crabby because his whole life he has seen failure been pushed around and not taken seriously, and every time he does something good and starts to get somewhere or make something of himself, he gets shot down to rock bottom. Thus causes people to become isolated and keep to them selves, however, Lennie, a man who isnt aware of social and cultural barriers, talks to crooks, and tells him about his farm. For the first time ever in his life Crooks sees a light, an opportunity for success and to be free, thus sorta bring himself out of isolation, to life in a happier place, a dream land, the land in which every hard working man such as himself, George, Candy, and even Lennie dream of. That takes Crooks to a new level of thinking. Curleys wife and himself were married at a young age, he promised her to have a good life and be happy. Unfortunately she was too young to know what she had gotten herself into. Curley couldnt love his wife because he didnt trust her, nor did he trust is co-workers, he considered he to be a tart because of the looks she gave people. However, little id anyone notice, those were not looks of lust, nearly looks of conversation. She was lonely, very lonely, and didnt have a single person to talk to, didnt have a job and could not get out fending for herself. She was isolated in...
