Cache-Enhanced Dynamic Movement-Based Location Management Schemes for 3G Cellular Networks.
Cache-Enhanced Dynamic Movement-Based Location Management Schemes for 3G Cellular Networks A Thesis Presented in Partial Fulfillment of Requirements for the Degree of Master of Science in the College of Arts and Sciences, Georgia State University, 2003 by Krishna Priya Patury Committee: ____________________________________ Dr. Yi Pan, Chair ____________________________________ Dr. Anu Bourgeois, Member ____________________________________ Dr. Alex Zelikovsky, Member ____________________________________ Date ____________________________________ Dr. Martin D. Fraser Department Chair Abstract Keeping track of mobile terminals moving from one place to another has been and will always be one of the key issues in mobile communication, be it cellular or Personal Communications Service. Location management involves two major kinds of operations: Location update- by which the system keeps track of the location of the mobile terminals that are not in conversation and Paging which is a search process by which the system searches for the Mobile Terminal by sending polling signals to cells in the paging area (which may include one or more cells). To perform either of these operations would incur a significant amount of cost, which should be minimized in the systems. Many mobility management schemes have been proposed as of now for 2-tier Cellular/PCS networks but none

Prior to this, business decisions were made that determined if the use of technology or PC's were required. Contrast this with today's high-tech world, where decisions are now influenced by the technology available. Home computers were seen as a luxury item less than a ten years ago (Vacca, 2005, p21), but are now a major part in many people's lives. The rise of computer technology has obviously enhanced our lives in many ways, such as enabling improved productivity and efficiency at work, school, and home. Anyone with access to a computer and the Internet now has unparalleled
The Story of Television
Einführung in das Studium der Medienkultur : Radio/Fernsehen Prof. Dr. Wolfgang Settekorn WS 2001/02 The Story of Television Ilkhan Akyürek Fibigerstr. 163/307 22419, HH Tel. 0179-3206737 Matr.-Nr.:5379176 Preface Not many know that there are more television sets in the world than there are telephones. Even the television professionals find it hard to believe. However, the statistics prove it to be true; according to official figures from the International Telecommunication Union there were 565 million telephones in 1983, and 600 million television sets. Other figures are just as impressive: in Belgium, from 1967 to 1982, the average time spent watching television by children from 10 to 13 years, increased from 82 to 146 minutes per day. Stupefying in every sense of the word. Our senses are assailed every day by the attraction of the visual message. Its all-pervasiveness and instantaneity are finely tuned to our way of thinking, whether we be hard-pressed or lazy. We expect from it effortless pleasure and hot news. A Chinese proverb tells us a picture is worth ten thousand words. But the stupefaction takes its toll and we thirst for more. Images pour over us in a never-ending torrent. Television has already modified our social behavior. It fosters, for example, our taste for things visual the impact of the picture and its colors. It encourages in us a
Java-Programmed Library System
The Library System Joel Goncalves Computer Science (Bsc) Abstract A simple information system for the school library was designed, where records of books could be added, deleted or printed to the screen. The classes Record and Library were created in order to represent the main purpose of the project, which was storing information regarding a particular book in a collection of book records allocated in the Library class. From the Library class we can access these records, edit them, or get the data contained in them. We can also get a list of all the records in the collection printed out to the screen. . Introduction The laboratory session was carried out with the use of a programming utility for Java named BlueJ. The theory, and main objective, of java programming is the interaction between objects. An object is regarded as an instance of a class, which can be seen as a set of instructions towards the construction and interactivity of the object - its data and behaviour. So while a class is responsible for characterising the objects, these are in charge of interacting with other objects (defined by other classes), if that is the programmer's will. In this lab session only 2 classes were used, Library and Record. The programming environment in which this laboratory was produced can be witnessed in the figure below. The objects are represented by the red
Project Management in the Business Environment
Final Project Plan: DDRS-B for DISA Brenda Allison Project Management in the Business Environment (MGT 573) James Hutcherson September 8, 2004 Final Project Plan: DDRS-B for DISA Project management is a carefully planned and organized effort to accomplish a specific goal. It includes developing a project plan and objectives, specifying tasks, preparing budgets, and timelines (http://www.mapnp.prg/library/ plan_dec/project/ project.htm). The use of project management processes can provide the Defense Finance and Accounting Service (DFAS) with techniques needed to eliminate obsolete financial systems. The DFAS is responsible for reporting all finance and accounting functions for the Department of Defense (DoD). Problem Statement Multiple finance and accounting automated information systems have been used to maintain identical financial functions and processes in the DoD. Considerable cost has been incurred for the last two decades as a result of government agencies not optimizing resources. The Defense Departmental Reporting System-Budgetary (DDRS-B) should be used by the Defense Information Systems Agency (DISA) to reengineer and consolidate existing processes into a standard departmental reporting system that will reduce these costs. DDRS-B supports the DoD need for a single financial management system that standardizes financial reporting. Current systems are
What are the purposes of ethnic monitoring? Give examples of its use.
What are the purposes of ethnic monitoring? Give examples of its use. Outline the difficulties in implementing ethnic monitoring, including those that arise in accurately classifying an individual's 'race'? Ethnic monitoring is a controversial subject that can basically be defined as the collection of racial data and statistics. Controversy exists because of the way in which information is collected, and the uses to which the data has, or in some cases has not, been put. Despite the debates about the validity of the collection of racial data, it is still collected, and has been since the 1960s. This very fact illustrates the way in which it is felt that the knowledge of an individual's 'race' is necessary to allow the study of social divisions, and the position of the individual within society. There are three primary purposes for the collection of racial data. The first of which is the most basic element of fact finding. It is a common trait of bureaucratic societies to collect information about everything possible, regardless of the need for it, or whether there is any potential advantage in having access to the data. The pointlessness of this sort of data collection is illustrated by the fact that between 1966 and 1973, data was collected about immigrant school pupils in the UK, but the government later admitted, that "no use was made of the data" (Skellington, 1992).
The film I have chosen is 'Goodfellas' directed by Martin Scorsese in 1990, based on the novel by Nicholas Pileggi 'Wiseguy'. The reason for this is that it gained many awards for the cinematography used and partly through personal preference.
Film Form and Genre Assignment 1 Give a detailed commentary on a sequence, or sequences from a film of your choice in terms of two of the any of the following: mise-en-scene; editing; use of colour; lighting; sound; special effects. The film I have chosen is 'Goodfellas' directed by Martin Scorsese in 1990, based on the novel by Nicholas Pileggi 'Wiseguy'. The reason for this is that it gained many awards for the cinematography used and partly through personal preference. The scene I have chosen is called 'Cast of characters; Tommy's a "funny guy". This is the post-transitional scene from when the lead character was an adolescent to becoming a young man. The purpose of the scene is basically to establish his friends and the social community in which he associates with. The main influence as to why I chose this scene is that of the cinematographic content and technical structure in relation to the film narration. I have chosen to discuss the sound elements of the scene and mise-en-scene. I chose sound as it is a key element in the structure of the narration and form of the scene. I chose to discuss mise-en-scene as the relationship of each element involved has important significance to the cinematography. The sequence is set in 'Sonny's Bamboo Lounge', a lounge bar and a regular mafia 'types' hang out, in down town New York, 1963. Sound There are three main types of
Impact of Social Networking on e-business
CSE 306 Research Portfolio Part 1 Research Paper Impact of Social Networking on e-Business Abstract The advent of the web2.0 has resulted in the upsurge of users onto the internet through their daily activities on social networking sites. Business firms in search of suitable means to strengthen the relationship between their customers and suppliers have sought to achieve this through such social networks. This paper examines the impact of social networks on e-business within firms, discussing some opportunities and possible risks firms could be exposed to. 1.0 Introduction S ince the advent of web2.0, the internet has evolved from static screenfulls to real time interactions between users, resulting in a new internet ecosystem characterized by social collaborative technologies. The advancement of such technologies has led to the emergence of new subsidiaries of network sociology based on traditional and modern complex networks such as social network sites (SNSs), blogs, wikis, folksonomy etc. the fast pace at which these SNSs are growing in recent years has resulted in several Online Social Networks (OSN) such as Facebook, Friendster, Hi5, MySpace, to mention but a few. Social networking (SN) may be defined as an internet based collection of individuals, organizations or other social entities that are interconnected through meaningful relationships that allow them
Setting up Microsoft Excel spreadsheet to simulate projectile motion.
Access Physics Simulating Projectile Motion Using Microsoft Excel V.J. Clarke Setting up Microsoft Excel spreadsheet to simulate projectile motion. The study of the motion of a projectile, called ballistics can be simulated mathematically by use of a spreadsheet, i.e. Microsoft Excel. To create a simulation, a few assumptions have to be made about the projectile, its launch device, and the forces acting on it in a perfect situation. The mass of the projectile is irrelevant because the acceleration due to gravity is roughly the same wherever you are on Earth, and what ever the mass of the object. I assumed that acceleration due to gravity was a constant 9.8 meters/s/s, that air resistance was negligible, and that the projectile itself was suitably streamlined to reduce drag. In fact, for calculations concerning short-range projectile motion, air resistance can be totally disregarded, but calculations concerning real life long-range artillery would need to include a compensation factor to make up for this loss of momentum. The only force acting on the projectile during its flight is the constant downward vertical force caused by gravity of 9.8 N. Formulas used. U = Muzzle Velocity (velocity that projectile leaves the gun, measured in meters per second [m/s], in this case Muzzle Velocity is always 400m/s ) a = Acceleration due to gravity, rounded to a constant 9.8
