ABSTRACT
An automotive propulsion concept is presented which
utilizes liquid nitrogen as the working fluid for an open
Rankine cycle. Ambient heat exchangers are used to power
an engine that is configured to maximize heat transfer during
the expansion stroke. If sufficient heat input during the
expansion process can be realized then this cryogenic
propulsive system would provide greater automotive ranges
and lower operating costs than those of electric vehicles
currently being considered for mass production.
The
feasibility of meeti ....etc

S.N.M.I.M.T, MALIANKARA

ABSTRACT
The ejector expansion refrigeration cycle (EERC) is a variant of the standard vapor compression cycle in which an ejector is used to recover part of the work that would otherwise be lost in the expansion valve. In initial testing EERC performance was poor, mainly due to thermodynamic nonequilibrium conditions in the ejector motive nozzle. Modifications were made t ....etc

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

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

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.

CRYOGENIC POWER CYCLE

Sparse Bayesian Learning Of Filters For Efficient Image Expansion

Image Processing- Dotnet

We propose a framework for expanding a given image using an interpolator that is trained in advance with training data, based on sparse Bayesian estimation for determining the optimal and compact support for efficient image expansion. Experiments on test data show that learned interpolators are compact yet superior to classical ones. ....etc
