1.INTRODUCTION

Quasi turbine is a zero vibration continuous combustion rotary engine having four faces articulated rotor with a free and accessible centre rotating without vibration nor dead time and producing a strong torque at low rpm under a variety of modes and fuels. The quasi turbine is also an optimization theory for extremely compact efficient engine concept.

It is a new engine concept from Canada which offers a design similar to that of rotary engines but with the advantages of a gas turbine-all wit ....etc

INTRODUCTION
The potential of cryogenic energy storage for automotive propulsion as an alternative to the electrochemical batteries for zero-emission vehicles (ZEV).
It is anticipated that use of an inert cryogen, such as liquid nitrogen(LN2), as an energy storage would not pose any environmental burden, and in particular would avoid the issues of heavy metals pollution associated with lead-acid batteries.

INTRODUCTION TO AMMONIA
__

Ammonia is one of the most important basic chemical of the world, ranking with materials such as sulfuric acid and sodium carbonate. In the fertilizer field, anhydrous ammonia itself has become the major supplier of the fertilizer nitrogen in India and it is also important inter mediate in production of more complex chemicals.
The major use of ammonia, both directly and indirectly, is as an intermediate in the fertilizer area. There are many other uses, although relatively minor, in ....etc

FREE FROST HEAT EXCAHANGER
ABSTRACT
A new concept has emerged in the field of zero - emission vehicles : the cryogenic automobile . The cryogenic automobile uses nitrogen , stored in liquid state , as its working fluid . The liquid nitrogen is pressurized , then vaporized in an economizer through which the exhaust from the expander runs in counter flow . The resulting gaseous nitrogen is superheated in an ambient temperature gas which is injected into a quasi isothermal expander to produce the system ....etc

DESIGN AND FABRICATION OF PULSE TUBE REFRIGERATION SYSTEM

ABSTRACT
Cooling effect at one end of a hollow tube with a pulsating pressure in the inside gas, was first observed by Gifford and Longsworth in early sixties. This marks the inception of one of the most promising cryogenic refrigerators known as 'pulse tube refrigerator' (PTR). Cryogenics is the science of low temperature. Cryogenics refers to the entire phenomenon occurring below -150 C or 123K. Cryogenic engineering involves the design and development of system ....etc

OPTIMIZATION OF CURE CYCLE TIME OF A BIAS TRUCK LUG TYRE BY STUDYING THE CURE EQUIVALENTS IN ISOTHERMAL AND NON-ISOTHERMAL CONDITIONS

INTRODUCTION
Curing is a process in which the viscoelastic rubber is converted into three-dimensional networks by tying up of all independent chains. Uncured rubber is a viscoelastic fluid, which has poor physical properties and undergoes deformation easily. Curing process reduces the flow of rubber material. And also reduces the amount of permanent deformation after the removal of deforming for ....etc

A Z-source inverter is a type of power inverter, a circuit that converts direct current to alternating current. It functions as a buck-boost inverter without making use of DC-DC converter bridge due to its unique circuit topology.
Impedance (Z-) Source networks provide an efficient means of power conversion between source and load in a wide range of electric power conversion applications (dc dc, dc ac, ac dc, ac ac) , . Z-source-related research has grown rapidly since it was first proposed in 2002 by Prof. F. Z. Peng. The numbersof ....etc

MAGNETORHEOLOGICAL FLUID DAMPER
1.INTRODUCTION
Vibration isolators or dampers are commonly used to mitigate vibrations in structures or machines. The isolators are typically passive and they are designed to reduce the vibration of the most undesired frequency. However, in many applications, the excitation frequency varies across a large range. In a semi-active device, the stiffness or damping can be adjusted during operation. Changing the stiffness of the support device can be exploited by moving the eigenfrequency of t ....etc

1. ABSTRACT
Mainstream applications such as file copy/transfer, Web, DBMS, or video streaming typically issue synchronous disk requests. As shown in this paper, this fact may cause work conserving schedulers to fail both to enforce guarantees and to provide a high disk throughput. A high throug ....etc
