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, the ....etc

ABSTRACT
With the increasing use of electronics and electronic commerce in our day-to-day lives, the importance of fraud-proof identification and recognition systems for use in security applications has grown .The improved understanding of biological systems and the ability to model them using computer algorithms has led to utilization of biometrics in authentication systems. Voice, Iris, Face, Signature, Hand Geometry are the biometrics that have been studied and applied to various kinds of identificati ....etc

Cell Centered Database

Abstract :

The Cell Centered Database (CCDB), launched in 2002 as one of the first Internet databases for cellular imaging data, makes 3D microscopic imaging data available to the structural biology and neuroscience communities. This database houses structural and protein distribution information derived from confocal, multiphoton, and electron microscopy, including correlated microscopy. Through this publicly accessible resource based at the University of California, San Diego (UCSD), researchers can query the ric ....etc

There are currently many research groups active in the field of photovoltaics in universities and research institutions around the world. This research can be categorized into three areas: making current technology solar cells cheaper and/or more efficient to effectively compete with other energy sources; developing new technologies based on new solar cell architectural designs; and developing new materials to serve as more efficient energy converters from light energy into electric current or light absorbers and charge carriers.

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 piracy. T ....etc

GLASS FIBER REINFORCED CONCRETE

When someone says fiberglass, we think of insulation or boats or Corvettes, but maybe we should think of concrete. Technically, fiberglass is simply very fine glass fibers. The material used to make boats or other products, although called fiberglass, is really glass fiber reinforced plastic-glass fibers in a polymer matrix. If, instead of the polymer, we use portland cement and sand, the resulting material is glass fiber reinforced concrete--GFRC or sometimes GRC (the Brits call it glassfibre reinf ....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 recover ....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 yes 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 informatio ....etc
