ABSTRACT

A new operational mode for diode-clamped multilevel inverters termed quasi two-level operation is proposed. Such operation aims to avoid the imbalance problem of the dc-link capacitors for multilevel inverters with more than three levels and reduces the dc-link capacitance without introducing any significant voltage ripple at the dc-link nodes. The proposed operation can be generalized for any number of levels. The validity of the proposed multilevel inverter operational mo ....etc

Cummins Crankshaft and Bearing Analysis Process

1. INTRODUCTION
This paper outlines the steps taken for the preliminary crankshaft and bearing design
analysis at Cummins. Major crankshaft dimensions must be chosen early in the engine design
process because they affect overall engine dimensions. Proper selection of the crank dimensions
requires multiple design iterations to avoid design alterations during the development stage when
any change is very costly. Therefore, the crankshaft and bearing analysis sho ....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 o ....etc

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 offers a design similar to that of rotary engines but with the advantages of a gas turbine-all within the confines of a chamber based on ....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.

Present project is designed using 8051 microcontroller to avoid railway accidents happening at unattended railway gates, if implemented in spirit. This project utilizes two powerful IR transmitters and two receivers; one pair of transmitter and receiver is fixed at up side (from where the train comes) at a level higher than a human being in exact alignment and similarly the other pair is fixed at down side of the train direction. Sensor activation time is so adjusted by calculating the time taken at a certain speed to cross at least one compart ....etc
