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 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

Adaptive Replacement Cache

Abstract :

We consider the problem of cache management in a demand paging scenario with uniform page sizes. We propose a new cache management policy, namely, Adaptive Replacement Cache (ARC) that has several advantages. In response to evolving and changing access patterns, ARC dynamically, adaptively, and continually balances between the recency and frequency components in an online and self tuning fashion. The ARC uses a learning rule to adaptively and continually revise its assumptions about the workload.

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

Introduction to wireless technology:
Mobile Technology is exactly the word which implies- the technology which is portable.

In 1887 the scientist named Henrich Heartz, concluded that we can propogate an EM wave in space with velocity equal to light (300M m/sec).
Later in 1889, the above theory was developed by scientist named Marconio by t ....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

The electrowetting behavior of mercury and other liquids on variably charged surfaces was probably first explained by Lipmann in 1875 and was certainly observed much earlier. Froumkin used surface charge to change the shape of water drops in 1936. The term electrowetting was first introduced in 1981 to describe an effect proposed for designing a new type of display device (G. Beni and S. Hackwood, Appl. Phys. Lett. 38, 4, pp.207-209, 1981]. Digital microfluidic manipulation of chemical & biological fluids was first investigated by J. Brown in 1 ....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

Seminar report
Abstract
The storage networking is a dedicated, high-speed network established to directly connect storage peripherals. It allows the direct communication between the storage devices and the client machines on the network. It provides a efficient solution for historical view of server attached storage. The emergence of storage networking brings a new trend in today s networking technology. The two-major compone ....etc

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
