Definition
Every action of the computer takes place in tiny steps, each a billionth of a second long. A simple transfer of data may take only one step; complex calculations may take many steps. All operations, however, must begin and end according to the clock's timing signals.

The use of a central clock also creates problems. As speeds have increased, distributing the timing signals has become more and more difficult. Present-day transistors can process data so quickly that they can accomplish several steps in the time that it takes a wir ....etc

Abstract-
A pulse skipping control strategy is proposed to improve efficiency of grid-tied inverters at light loads. To maximize the efficiency of pulse skipping operation mode, three key parameters are identified and optimized based on a loss model, which is developed to find the maximal efficiency points using a three-dimensional search technique. A 200W prototype inverter was setup to verify the proposed control strategy. The experimental results show that the proposed pulse skipping control strategy greatly impr ....etc

Abstract
Buffer overflow exploits make use of the treatment of strings in C as character arrays rather than first-class objects. The manipulation of arrays as pointers and primitive pointer arithmetic makes it possible for a program to access memory locations which it is not supposed to access. There have been many efforts in the past to overcome this vulnerability by performing array bounds checking in C. Most of these solutions are either inadequate, inefficient or incompatible with legacy code. In this report we present an efficien ....etc

Active pixel sensor

An active-pixel sensor (APS), also commonly written active pixel sensor, is an image sensor consisting of an integrated circuit containing an array of pixel sensors, each pixel containing a photodetector and an active amplifier. There are many types of active pixel sensors including the CMOS APS used most commonly in cell phone cameras, web cameras and in some DSLRs. Such an image sensor is produced by a CMOS process (and is hence also known as a CMOS sensor), and has emerged as an alternative to charge-coupled device (C ....etc

active pixel sensor (APS)

An active pixel sensor (APS) is an image sensor consisting of an integrated circuit containing an array of pixels, each containing a photodetector as well as three or more transistors. Since it can be produced by an ordinary CMOS process, APS is emerging as an inexpensive alternative to CCDs.

Architecture
Pixel: The standard CMOS APS pixel consists of three transistors as well as a photodetector.
The photodetector is usually a photodiode, though photogate detectors ar ....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
