Data Sharing Among Mobile Users

Abstract :

Applications that rely on replicated data have different requirements for how their data is managed. For example, some applications may require that updates propagate amongst replicas with tight time constraints, whereas other applications may be able to tolerate longer propagation delays. Some applications only require replicas to interoperate with a few centralized replicas for data synchronization purposes, while other applications need communication between arbitrary replicas. Similarly, th ....etc

Connectionist Systems

Abstract :

The rapid proliferation of computers through all organizations makes it necessary to look at manufacturing in a new way to meet rapidly changing market conditions and the business environment. By using networking within the organization manufacturing units can work at high efficiencies and make decisions that affect their operations in a most informed way.
However, the extension of this networking to physical levels in the shop floor needs to be given special attention since this is often the weak page ....etc

Data Compression

Abstract :

It is very interesting that data can be compressed because it insinuates that information that we generally pass on to each other can be said in shorter information units (infos). Instead of saying Ëœyesâ„¢ a simple nod can do the same work, but by transmitting lesser data. In his 1948 paper, A Mathematical Theory of Communication, Shannon established that there is a fundamental limit to lossless data compression. This limit, called the entropy rate, is denoted by H. The exact value of H depends on the ....etc

CDMA Technology

Abstract :

CDMA was developed by QUALCOMM Incorporated, a company in San Diego, California. QUALCOMM engineers decided to do something different and applied spread spectrum techniques to a multiple access system, which ultimately became CDMA.
In spread spectrum, instead of giving each person a channel, or each group of 3 or 8 people a time slot, CDMA puts everyone in the same channel at the same time.
At first thought, it would seem to be an impossible task to make work, but it does work. The reason it works is expla ....etc

3D Visualization In Computer Graphics

Abstract :

In the last several years, three-dimensional computer graphics has become a critical technology in the PC world. 3D graphics capability is a prerequisite for two major markets: Computer-aided industrial and mechanical design (for which the majority of workstations and high-end PCs are sold today) and entertainment (especially computer games, which are driving significant new PC hardware and software purchases by consumers).

Digital Rights Management

Abstract :

The electronic commerce with digital content over the open, unsecured network like the Internet provides opportunities as well as risks for content providers. So far, most content providers of media and entertainment content such as music, film, or print content have not been successful or profitable in charging consumers for their products. Nor have they been successful in creating the technology frameworks required to remunerate on the one-hand content owners and on the other hand protect against p ....etc
