1. ABSTRACT

microRNAs are small, regulatory ssRNA molecules involved in post-transcriptional gene silencing. Numerous miRNAs have been implicated in different types of cancers. The aim of this study is to create a bipartite graph connecting miRNAs and different cancers. We intend to identify miRNA hubs that are implicated in a large number of cancer types. Studying the function of such hub miRNAs is likely to shed light on the common pathogenesis mechanisms shared across the various cancer types .A combination of li ....etc

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

Automatic Railway Gate Controller Using Stepper Motor

ABSTRACT

This project work aims at the design, development, fabrication and testing of working model entitled Automatic Railway Gate Controller. It is basically related to Radio communication and signalling system. An Automatic Railway gate controller is unique in which the railway gate is closed and opened or operated by the Train itself by eliminating the chances of human errors.
The largest public sector in India is the Railways. The network of Indian Railwa ....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

Variable sweep wings
ABSTRACT
VARIABLE-SWEEP WING
A variable-sweep wing is a wing configuration that allows to alter planform for various flight conditions. A variable-sweep wing can be moved during flight-usually between a swept-back position and a straight position. This allows it to take advantage of the aerodynamics of a swept wing at high speeds while avoiding the drawbacks of such a design at lower speeds. It is successful in this respect, but the added mass and complexity required counter the benefits and stand ....etc

1.0 INDRODUCTION
An escalator is a moving staircase conveyor transport device for carrying people between floors of a building. The device consists of a motor-driven chain of individual, linked steps that move up or down on tracks, allowing the step treads to remain horizontal.
Escalators are used around the world to move pedestrian traffic in places where elevators would be impractical. Principal areas of u ....etc

Ocean thermal energy conversion (OTEC) is a method for generating electricity which uses the temperature difference that exists between deep and shallow waters to run a heat engine. As with any heat engine, the greatest efficiency and power is produced with the largest temperature difference. This temperature difference generally increases with decreasing latitude, i.e. near the equator, in the tropics. Historically, the main technical challenge of OTEC was to generate significant amounts of power, efficiently, from this very small temperature ....etc
