Negative Supercharging




INTRODUCTION



Negative Supercharging is a highly advanced and complex Thermo Fluid Dynamic Process that converts the positive exhaust pressure produced after combustion into Negative Boost within the cylinders to pull more air into the engine. Negative Supercharging does NOT use any type of blower device and works the opposite to conventional supercharging by pulling air into the engine instead of pushing air like convention ....etc

Abstract:
Deregulation of the electric utility has created unprecedented opportunities for the growth in the market for alternator. In order to extract the maximum benefit from this situation improvement must be made in the control and protection features incorporated in alternator. The automatic voltage regulator has a key role to improve alternator performance. This project i ....etc

NEGATIVE SUPERCHARGING


INTRODUCTION

WHAT IS MEAN BY SUPERCHARGING ?

IN THE NEGATIVE SUPERCHARGING PROCESS, POSITIVE EXHAUST PRESSURE CONVERTED INTO NEGATIVE BOOST TO PULL MORE AIR INTO THE ENGINE.

OPPOSITE TO CONVENTIONAL SUPERCHARGING.

MAGLEV TRAINS



ABSTRACT:

The concept of magnetically levitated or maglev trains is of very much interesting.
The conventional trains with wheels and guide rails turn to be uneconomical beyond 200 km/hr because at this high speed, air resistance and hence the drag force increases. Therefore, they are very much expensive and require intensive maintenance. Maglev trains avoid these disadvantages and prove highly beneficial.

It is based on the three principles viz. electrod ....etc

EFFECT OF NEGATIVE SUPERCHARGING ON INTERNAL COMBUSTION
ENGINE


ABSTRACT
Until recently, Automobile manufacturers uses supercharger & turbocharger to supply
air-fuel mixture at a pressure above atmospheric. Up to 40% increase in power & torque may be
obtained by supercharging. As a typical example , in the Chrysler 2.2L turbocharged engine, the
turbocharged provides 35% more torque & 50% more power compared to the same engine
without turbocharger. To achi ....etc

Maglev Trains


1. INTRODUCTION
1.1 History
First generation Maglev systems have been developed in Japan and Germany.
Hermann Kemper began research on Maglev system in Germany and conducted successfully tests in the 1930’s (receiving a patent in 1934).
In the late 1960’s the German government began a study of traffic and modes which led to the development of very high speed maglev system by the German ministry of research and technology. The development included short stator, EDS and EMS technology and sy ....etc

Nano-Optical Superlenses with Negative-Index Sandip Tiwari, Cornell U Metamaterials
We have demonstrated experimentally the imaging at 1.55 µm wavelength by a generalized photonic crystal superlens (Fig. 1) nanofabricated in InGaAsP/InP heterostructure. By designing a suitable lens surface termination, an image spot size of 0.122 was achieved, demonstrating superlens imaging with sub-wavelength resolution well below the diffraction limit (0.52).

We have created a new nano-optical microlens that focuses infrared light at tele ....etc
