...Video on Demand (Multimedia databases). - -Video on Demand (Multimedia Databases Introduction Video on Demand (VoD ) is an interactive multimedia system . The fundamental process of its working is same as that of cable television In this , the customer has the option of selecting a movie from a large video database and can watch different programs as and when required . It seems that the video rental shop is present at home . Research is going on to improve the quality of VoD-related services . Some of the VoD-related applications are providing Video Films on Demand , Local news and Weather Forecasting , Games , music and Leisure , Education and Remote Learning Facilities , Home Shopping and Other Consumer Services , Banking etc . This system has three main components . These are Video server : it stores and provides access to programs Data delivery network : it is the linking source for subscriber Set-top box : It is the interface between TV equipments and VoD services MPEG (Motion Picture Experts Group ) is a group of people who work for ISO (International Standards Organization ) to generate digital video standards i .e producing sequences of images in time and to generate audio compression . Various kind of MPEG are ranked on the basis of the speed (in CD-ROM data rates ) at which they deliver video to consumer devices . For example , the speed of MPEG-1 was 1 .5 Mbit /s , MPEG-2 with improved resolution deliver broadcast and HDTV quality video . Over...

...Computers are around our live. In Hong Kong, most citizens know how to use computers. Recent decade, the Internet service is used widely, such as trading, working, chatting and playing online games. All these can be finished in a virtual world. Therefore, people use computers with a lot of hours to do everything because of convenience and efficiency, and so, far less time to interact with others in the real world. When people stay in the virtual world more, their communication abilities will be weakened because of lacking practicing body language and oral skills. They will start socially withdraw as they cannot integrate into the society. The process will be repeated and become a vicious circle. As a result, they will become hikikomori and this phenomenon will create many social problems like no economic contribution and family violence, which is due to family member’s misunderstanding about them and then they will lose temper because of weak communication ability. These consequences would be faced in different ages. However, as teenagers, the next generation, constitute a mainstay of our society, strengthen young people’s communication abilities is to brook no delay for better future development. We cannot work without computers since everything come to digital nowadays. So, we should not ask teenagers leave computers far away. It is not workable no matter they use it for work or entertainment. Nevertheless, the problem of teenagers’ weak communication abilities that caused...

...The Cosmopolitan Society and its Enemies Ulrich Beck I N THIS article I want to discuss three questions: (1) What is a cosmopolitan sociology? (2) What is a cosmopolitan society? (3) Who are the enemies of cosmopolitan societies? What is a Cosmopolitan Sociology? Let me start by attempting to nail a pudding to the wall, that is, defining the key terms ‘globalization’ and ‘cosmopolitanization’. At the beginning of the 21st century the conditio humana cannot be understood nationally or locally but only globally. ‘Globalization’ is a non-linear, dialectic process in which the global and the local do not exist as cultural polarities but as combined and mutually implicating principles. These processes involve not only interconnections across boundaries, but transform the quality of the social and the political inside nation-state societies. This is what I define as ‘cosmopolitanization’: cosmopolitanization means internal globalization, globalization from within the national societies. This transforms everyday consciousness and identities significantly. Issues of global concern are becoming part of the everyday local experiences and the ‘moral life-worlds’ of the people. They introduce significant conflicts all over the world. To treat these profound ontological changes simply as myth relies on a superficial and unhistorical understanding of ‘globalization’, the misunderstandings of neoliberal globalism. The study of globalization and globality, cosmopolitanization and cosmopolitanism...

...YOUR ECONOMETRICS PAPER BASIC TIPS There are a couple of websites that you can browse to give you some ideas for topics and data. Think about what you want to do with this paper. Econometrics is a great tool to market when looking for jobs. A well-written econometrics paper and your presentation can be a nice addition to your resume. You are not expected to do original research here. REPLICATION of prior results is perfectly acceptable. Read Studenmund's Chapter 11. One of the most frustrating things in doing an econometrics paper is finding the data. Do not spend a lot of time on a topic before determining whether there is data available that will allow you to answer your question. It is a good idea to write down your ideal data set that would allow you to address your topic. If you find that the available data is not even close to what you had originally desired, you might want to change your topic. Also, remember that knowing the location of your data – website, reference book, etc – is not the same as having your data available to use. It may take a LONG time to get the data in a format that EVIEWS can read. Do not leave this till the last minute. For most data, I enter the data into Excel first. I save the Excel sheet in the oldest version, namely MS Excel Worksheet 2.1 . The reason is that format can be read by most programs whereas newer formats may or may not be read. Eviews easily reads an Excel sheet 2.1 version. You should use the...

...SAS Global Forum 2009 Pharma, Life Sciences and Healthcare Paper 174-2009 Clinical Trial Reporting Using SAS/GRAPH® SG Procedures Susan Schwartz, SAS Institute Inc., Cary, NC ABSTRACT Graphics are a powerful way to display clinical trial data. By their very nature, clinical trials generate a large amount of information, and a concise visual presentation of the results is essential. Information about the patient population, drug dosages, clinical responses, and adverse events must be clear. Clinical laboratory results need to be presented within the context of acceptable limits, and subtle changes over time must be highlighted. This presentation will show, by example, how such graphs can easily be created using the SAS/GRAPH® SG procedures. The techniques that will be emphasized in this presentation include: • • • • • • Creation of a dose response plot by overlaying multiple plots in one graph Construction of a hematology panel using treatment regimen and visit numbers as the classification variables Presentation of a matrix of liver function tests (LFTs) for at-risk patients Aggregation of data into on-the-fly classification variables using user-defined formats Getting the axis you want using built-in best fit algorithms Generation of publication-ready graphs in color and in black and white INTRODUCTION The new SAS/GRAPH procedures—SGPLOT, SGPANEL, and SGSCATTER—provide new tools for viewing and reporting data collected during clinical trials. The SG procedures are an extension...
