Abstract
CFD Modelling of Hot-Machining Operation is a machining method conducted on conventional machine tools in which work piece is preheated before cutting operation to become softer and thereby to reduce its shear strength. Here in Final Year B.Tech Project work this work is assigned to me for understanding the Hot-Machining prospects. In our Work the job to be machined is of High Manganese- Steel. As we know the machining of these materials has always been a great challenge. ....etc

HIGH SPEED MACHINING
ABSTRACT
Over the past 60 years, high speed machining (HSM) has been applied to a wide range of metallic and non-metallic work piece materials including the production of components with specific topography requirements and machining of materials with hardness of 50 HRC and above.
With most steel components hardened to approximately 32-42 HRC, machining operations currently include:
Rough machining and semi-finishing of the material
Heat treatment to ach ....etc

INTRODUCTION

The next Pearl Harbor will not announce itself with a searing flash of nuclear light or with the plaintive wails of those dying of Ebola or its genetically engineered twin. You will hear a sharp crack in the distance. By the time you mistakenly identify this sound as an innocent clap of thunder, the civilized world will have become unhinged. Fluorescent lights and television sets will glow eerily bright, despite being turned off. The aroma of ozone mixed with smoldering plastic will seep from outlet covers as electric wires arc ....etc

Space is a hostile environment. No atmosphere, extreme variations in temperature and almost no energy sources, where even the slightest of mistakes can lead to a disaster. The vast emptiness of space is filled with radiation, mostly from the sun.

A normal computer unless given proper shielding will not be able to work properly. Thus special types of chips- rad hard chips are used.

Radiation hardened chips are made by two methods: -
Radiation hardening by process (RHBP)
Radiation hardening by design (R ....etc

BioCryptosystems for Authentication and Network Security-A Survey


I. INTRODUCTION
iometrics deals with identification of individuals based on their biological and behavioral characteristics. Autonomously, both biometrics and cryptography play a critical role in providing security to user information . In a cryptographic system the user authentication is tenure based. In this type of system the cryptographic keys used for encryption and decryption are long and random, hence cannot be memorized. This has led to store the cr ....etc

ABSTRACT
Continuously Variable Transmissions based on belts, pulleys, cones, discs, collectively friction transmissions, share many of the disadvantages of conventional hydraulic transmissions. CVTs require clutching mechanisms, hydraulic pumps to compress V belts between adjustable pulleys, and all have ablative belts, ....etc

ABSTRACT
Nowadays, digital memories are used in each and every fields of day-to-day life. Semiconductors form the fundamental building blocks of the modern electronic world providing the brains and the memory of products all around us from washing machines to super computers. But now we are entering an era of material limited scaling. Continuous scaling has required the introduction of new materials.
Current memory technologies have a lot of limitations. The new memory techno ....etc

ABSTRACT

Electromagnetic bombs are Weapons of Electrical Mass Destruction with applications across a broad spectrum of targets, spanning both the strategic and tactical. As such their use offers a very high payoff in attacking the fundamental information processing and communication facilities of a target system. The massed application of these weapons will produce substantial paralysis in any target system, thus providing a decisive advantage in the conduct of Electronic Combat, Offensive Counter Air and Strategic Air Att ....etc

Abstract
LaGrande Technology (LT) is a highly versatile set of hardware enhancements that will come to Intel processors, chipsets and platforms over the next 2 to 3 years. LT creates a hardware foundation, on the client PC platform, that can help protect the confidentiality and integrity of data stored or created from software based attacks. It does this by enabling an environment where applications can run within their own space, protected from all other software on the system. In turn, this can help to protect vital dat ....etc
