INTRODUCTION
Solid freeform fabrication (SFF) encompasses a class of processes that can be used to design and construct parts using a layer-additive approach. SFF processes are an outgrowth of rapid prototyping processes such as stereolithography for plastics and welding repair techniques employing laser, electron beam, or arc welding for repairing metal seal knife edges, turbine blade tips, or tooling dies. Current development efforts are expanding these repair techniques and applying principles from ....etc

ABSTRACT
Manufacturing process of gear is fairly complicated due to the presence of various simultaneous motions of the cutter and the job. In this paper, an attempt is made to generate meaningful design data for a spur gear and the corresponding rack form cutter necessary for the manufacturing process. Using these information, solid models for the cutter and blank are developed and finally gear-manufacturing process is simulated in a virtual manufacturing environment. The user can switch between design and manufacture mode at will. Th ....etc

A Light emitting diodes (LEDs) have gained broad recognition as the ubiquitous little lights that tell us that our monitors are on, the phone is off the hook or the oven is hot semiconductor.

The basic principle behind the emission of light is that: When charge carrier pairs recombine in a semiconductor with an appropriate energy band-gap generates light. In a forward biased diode, little recombination occurs in the depletion layer. Most occurs in a few microns of either P- region or N ?region, depending on which one is lightly doped.

In early times, the disposal of human and other wastes did not pose a significant problem, for the population was small and the amount of land available for the assimilation of wastes was large .Now due to rapid population growth and economic development in the country-Solid waste disposal has become a major environmental issue in India. Solid waste, often called the third pollution after air and water pollution, is that material which arises from various human activities and which is normally discarded as useless or unwanted it consists of the ....etc
