The Ping of Death uses a ping system utility to create an IP packet that exceeds the maximum 65,536 bytes of data allowed by the IP specification. The oversize packet is then sent to an unsuspecting system. Systems may crash, hang, or reboot when they receive such a maliciously crafted packet. This attack is not new, and all OS vendors have fixes in place to handle the oversize packets.

Digital Smell

Abstract :

The technology has so far targeted mainly our sense of sight and sound. To further enhance the virtual reality experience and another flavor to it, technology is now targeting your nose and tongue.
The application area of virtual reality is vast- from normal entertainment to the Internet and e-commerce application. You will be able to smell product before buying them online.
California-based Digiscents Inc. has developed the iSmell personal scent synthesizer. This small device connects through your pc via serial por ....etc

COOPERATIVE LINUX

Abstract
Software development for an embedded Linux system in most cases requires a free license of GCC (GNU C/C++ compiler) and accessories. Many developers find it disconcerting that the GNU tools are primarily available for Linux-based PCs. Any attempt to make GCC run under Windows in order to program an embedded Linux system has been fraught with problems until now. The popular Cygwin “ as a Unix/Linux emulation environment under Windows “ is muc ....etc

Abstract :

Current trends in computing technologies are drifting towards distributed and parallel computing. These topologies emphasize on concurrent access schemes. Because of distributed computing, the use of shared resources like databases, memory, etc. is growing. Locking mechanisms can be used effectively to achieve high concurrency levels without corrupting the resources. There are a wide range of synchronization protocols, some providing strong consistency while others granting weak consistency. There is a trade-off between complexi ....etc

1. INTRODUCTION

Hydro forming is a relatively new process, which uses water pressure to form complex shapes from sheet or tube material. Design studies suggest that automobiles can be made much lighter by using hydro formed components made of steel. Structural strength and stiffness can be improved and the tooling costs reduced because several components can be consolidated into one hydro formed part.
As the automobile industry strives to make car lighter, stronger and more fuel efficient, it will continue to drive hyd ....etc

VARI-FORM

ABSTRACT
The need for lighter, stronger, more rigid vehicle structures will increasingly require complex hydroformed structural tubes to increase strength, and decrease weight, cost and part count. This effort will increase the use of high strength, low alloy (HSLA) steel, in place of SAE 1006/1008 or 1010 steel. Traditional hydroforming techniques require the higher elongation of the latter materials. An alternative tube hydroforming process has been d ....etc

Hydroforming (or hydramolding) is a cost-effective way of shaping malleable metals such as aluminum or brass into lightweight, structurally stiff and strong pieces. One of the largest applications of hydroforming is the automotive industry, which makes use of the complex shapes possible by hydroforming to produce stronger, lighter, and more rigid unibody structures for vehicles. This technique is particularly popular with the high-end sports car industry and is also frequently employed in the shaping of aluminium tubes for bicycle frames, Hydro ....etc

INTRODUCTION
Efficient control of D.C motor speed is very economical to any industries for that reason we are using full wave rectifier in which we are using triacs as switches because of bi-directional nature of triacs we are preferred instead of using thyrister as a switches. To obtain a four quadrant operation we need 8 switches if we use thyristers (this circuit called dual converter) and if we use triacs we need 4 switches only.
