INTERNATIONAL RELATIONS - Essay Example Capitalism in the society leads to class structure between halves and halve nodes. The halves are the capitalist who owns all the resources, and have nodes are the labourers whose only means of subsistence is their labour power. The capitalist buy labour in the market likes any other commodity (EyalSzeleÃŒ nyi &Townsley 1998). The surplus of labour in the economy goes into the capitalist in the form of supernormal profit. The surplus arises due to the worker working overtime with no payment. If a worker is assign to work for a certain job within 10 hours, and the worker finishes the task in 7hours, the 3hours extra will go into capitalist profit. Capitalist is society trace origin from 13th to 16th century. The reasons for emergence of capitalism in society were due to the society need to use wealth to create more wealth. In pre-capitalist society, the profit from enterprise was shared among the society members. The land, labour and capital were not factors of production but communal resource. With the emergence of capitalism, labour was viewed as a factor of production. The profit for the entire company goes into the pocket of one person. Capitalism develops fully in 16th century with the industrial revolution and development of companies. Industrial revolution is a period of advancement of industries due technology and innovation. Advances of industries leads to few individuals accumulating a lot of wealth leaving others poor. The companies that were developed were in a group of people but everyone depend on herself. Industrialization lead to emergence of capitalist nations in 17th century that became economically powerful. In a capitalist economy, the level of completion is high to economic scarce resources. The owners of production face completion in prices of goods and services from other individuals in the society. The competition in the society will leads to alienation of the owner and workers. The

The corrosive nature of social networking websites Essay

The corrosive nature of social networking websites - Essay Example Social networking sites cause loneliness (Boyd d and Ellison: pp. 221). When joining these sites, for instance, Facebook, no one has the intention to get lonely while online. However, most research findings can prove that the more someone uses the internet services, the more the chances of getting lonely and depressed. This is because the sense of being happy rapidly drops after the first day of using the website. The loneliness issue arises because Facebook serves different purposes with everyone using what is meaningful to their social life. Therefore, through the consumption of so much content on such social networking websites, people lose their social bonding thus lowering their self-esteem and feeling which in turn increases loneliness. Social networking websites are creating a false sense of interaction. The society fosters real and meaningful kinds of relationships. They are supposed to be healthy to everyone because they act as role-shaping structures, increases the sense of belonging and the will to conquer problems. However, most of these social networks though created out of a simple idea of promoting social relationships, have been creating a wrong sense of connection (Kennedy, et al.: pp. 110). They are among the fastest growing companies with Facebook being on the lead. They have chat rooms that enable users to communicate with each other. These chat rooms make users glued to their computer screens, as they want to find out more from their online friends.

Analysis of SEEK Limited, Telstra Limited and Ansell Limited Essay

Analysis of SEEK Limited, Telstra Limited and Ansell Limited - Essay Example Another importance why I used the 10 year period data is that if the period is too short, there may be just the data for bull market, for instance from 201-2015. Moreover, a short time period data may result in inadequate information which in turn may result in misinterpretation. Therefore, I used the longer time period to select stock of the three companies to forecast the upcoming rates in order that legitimate forecasts of stocks may be possible. The data used for the chosen three companies: SEEK Limited, Telstra Corporation and Ansell were for the period of 2005-2015 to assess as well as make projections 3.

Energy, Metabolism and Cells - Essay Example Furthermore, there are four ways by which enzyme activity is regulated by the cell. Photosynthesis and Aerobic Respiration Photosynthesis and aerobic respiration are two intracellular processes that work hand in hand in order to bring about the chemical transformation of sunlight into usable energy, in the form of ATP (â€Å"Photosynthesis and Respiration,† 1999). Basically, photosynthesis is the process through which plants convert sunlight to glucose, with the chemical equation: 6H2O + 6CO2 ? C6H12O6 + 6O2. ATP for use by the plant itself is also produced by the light reactions of photosynthesis (Carter, 1996). However, since the main product of the photosynthetic process – glucose or sugar, C6H12O6 – needs further conversion into a form considered usable by the plant and animal body, this conversion is made possible by the process that complements photosynthesis: aerobic respiration (Farabee, 2007). Through aerobic respiration, ATP is produced from glucose. Th e chemical equation for aerobic respiration is C6H12O6 + 6O2 ? 6H2O + 6CO2 + 36 ATP (Burkett, 2005). This means that in the process, 36 units of ATP or energy is produced. In short, plants produce glucose through photosynthesis, and this glucose is consumed and utilized by the plant and animal to produce ATP through aerobic respiration. Photosynthesis itself is a complex process made up of the light and dark reactions. The Light Dependent Process, or Light Reactions, uses the direct energy of sunlight to produce energy carrier molecules – ATP and NADPH – needed in the second process, the Light Independent Process, or Dark Reactions, where glucose, or C6H12O6, are produced (Farabee, 2007). The Light Reactions in the thylakoid membrane of the chloroplasts, the require sunlight to strike the chlorophyll and carotene molecules in the leaves of plants in order to trigger a series of reactions that will eventually produce ATP and NADPH (Farabee, 2007). In the Light Reactions , the hydrogen atoms of water, H2O, are also removed for use in reducing NADP+ to NADPH (Kimball, â€Å"The Thylakoid,† 2011). In the ensuing Dark Reactions or Calvin Cycle, which occur in the stroma, carbon dioxide is captured and combines with RuBP, a 5-carbon chemical, to finally produce a 6-carbon glucose, C6H12O6 (Farabee, 2007). Now, in order for this glucose to be usable, it must be consumed by the plant itself or the animal but it must first be used to produce ATP through aerobic respiration. Aerobic respiration is a three-stage process where ATP is produced during each stage. Glycolysis, the first of the three stages, occurs in the cytoplasm and involves a 10-step process that ends up with the breakdown of glucose, C6H12O6, into two pyruvic acid molecules, C3H4O3, and in the process produces a net of 2 ATP and 2 NADH (Gregory, 2011). Each of the two pyruvic acid molecules now goes to the matrix of the mitochondrion for an intermediate process known as pyruvate oxidat ion or oxidative phosphorylation, and produces CO2 and an acetyl group. The acetyl group then combines with CoA to form Acetyl CoA, and producing 2 NADH in the process. In fact, there are actually two Acetyl CoA molecules at the beginning of the next stage, the Krebs Cycle, so there are two Krebs Cycles from one Glycolysis process (Burkett, 2005). The Krebs Cycle, which occurs in the matrix of the

Hannah and Her Sisters Essay Example for Free

Hannah and Her Sisters Essay Relationships in New York are as complex as the city itself. Nothing can be considered as sedentary because of the always changing temperaments of people, development in the place and other factors that contribute to change. It is surprising though that no matter how complex human relationships are; people (in New York) seem not to take it heavily. It may be because of their fast paced lifestyle that they don’t see the heavy impact of certain situations unless it has something to do with career goals. In the movie Hannah and Her Sisters, Woody Allen used comic archetypes to satirize relationships on New York City by exaggerating the kind of intricate relationships and character’s reactions towards situations in a comical way. He showed that people have the tendency not to care how absurd their relationships with others are as long as they maintain their image and keep up with their goals. The story revolved around the intertwined relationships of three sisters with their husbands and exes. To some cultures (other states), the circumstances that the sisters got into may not be dealt as light as they did. To others, the family might condemn the husband if he falls in love with his wife’s sister because it will cause conflicts between the sisters. Woody Allen made the characters in the movie treat the state of affairs in a romantic and funny way. Through the movie, Woody Allen showed that relationships in New York are that complicated however, people generally manage to maintain a positive outlook in life. It is noticeable that in the movie, Allen imposed a happy ending when all of the sisters are happily married.

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

The Economic Development Of Ghana Essay -- essays research papers

The Economic Development of Ghana Ghana is an African country located on the western side of Africa. Its neighbors are Burkina Faso to the north, Togo to the east, the Atlantic Ocean to the south, and Cote D'Ivoire to the west. It has a population of 18,100, 703 and a population density of 197 people per square mile. Ghana is 92,098 square miles and English is its official language. The capital city of Accra has around 1, 673,000 people residing in it. There are the physical statistics, now onto the more interesting part. The country's greatest strengths lie in its natural resources. In those terms, it is very rich. Cocoa, its biggest export, accounts for 15% of the world's supply. Also its gold production, in recent years, it's exported as many as one million fine ounces. Ghana also has a good supply of bauxite, diamonds, coffee, rice, cassava, timber and rubber. Moreover, since 1983, the economy has steadily grown. With economic recovery policies intact, the economy has raised 5% a year since 1983. Tourism also is growing within Ghana. Tourist rates are increasing also. With all these cash crops, costly goods, and economic restructuring, one would wonder why they need assistance at all. Ghana's weaknesses though, almost outweigh the strengths. Like most countries in Africa, Ghana is in heavy debt since its independence in 1957. It also suffers from high budget deficits. All of the foreign investors that come in only invest in the gold fields. The richest business, Ghana i...
