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

Cellular Digital Packet Data

Abstract :

Cellular Digital Packet Data is a technique, which is applicable over cellular network for quick transfer of data. It is applicable in providing a quick transfer of data over cellular networks. It transmits the packets over the cellular network in a reliable manner. Packet networks break a stream of data in to independent blocks of data called the packets. CDPD is wirelesses IP network that overlay on the existing AMPS cellular infrastructure. The CDPD raw channel modulation user rate is 19.2 kbps ....etc

Computer Forensics


Abstract :

Forensic computing is the process of identifying, preserving, analyzing and presenting digital evidence in a manner that is legally acceptable.(Rodney Mckemmish 1999).

From the above definition we can clearly identify four components:-

IDENTIFYING
This is the process of identifying things such as what evidence is present, where and how it is stored, and which operating system is being used. From this information the investigator can identify the appropriate recove ....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

Cellular Internet Protocol

Abstract :

This document specifies a protocol that allows routing IP datagrams to a mobile host. The protocol is intended to provide local mobility and handoff support. It can interwork with Mobile IP to provide wide area mobility support. Four fundamental design principles of the protocol are: (1) location information is stored in distributed data bases (2) location information referring to a mobile host is created and updated by regular IP datagrams originated by the said mobile host (3) location informat ....etc

Collective Intelligence

Abstract :

Collective intelligence is defined as the ability of a group to solve more problems
than its individual members. It is argued that the obstacles created by individual cognitive limits and the difficulty of coordination can be overcome by using a collective mental map (CMM). A CMM is defined as an external memory with shared read/write access that represents problem states, actions and preferences
for actions. It can be formalized as a weighted, directed graph. The creation of a network of pheromone ....etc

Configurable ALU's

Abstract :

The configuration of the Arithmetic Logic Unit has effect on the computation efficiency of the executing programs . It is a fact that a given hardware ALU configuration may be better suited for execution of a given computation structure . Thus maximum computation efficiency can be achieved if the underlying hardware configuration can be adjusted as required by the program structure . Since a program is sequence of algorithmic steps with varying c ....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 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
