Conceptual design Of Hybrid Scooter Transmission With Planetory Gear-Train

This paper presents a new design concept of transmissions for the hybrid scooters. These transmissions consist of a one-degree-of-freedom planetary gear train and a two degree of freedom planetary gear train to from a split power system and to combine the power of two power sources, a gasoline engine and an electric motor. In order to maximize the performance and reduce emissions, the transmissions can provide a hybrid scooter to run five operating modes. They are ele ....etc

Seminar on A Prevention to Train Accident



INTRODUCTION

Some times train driver may become help less in stopping the train in short distance. When sudden brakes are applied (air brake) due to large number of bogies they may collide with each other or derail from railway track or may climb one over another which leads to lot of damage. To reduce damage and to give stability to the bogies electromagnetic concept is used. And to avoid train accidents due to floods, sensors are used. Also by the continuity ....etc

Abstract

This thesis presents a unification of kinematic and force-based methods for the design and analysis of planetary gear trains along with a discussion of potential applications in tandem biking. Specifically, this thesis will provide a simple solution technique for the general case of a two-degree of freedom (2DOF) planetary gear train along with new graphical design aids. It will also address the use of epicyclic gear trains as a power coupling in a tandem bike.

In the current ....etc

Each mobile uses a separate, temporary radio channel to talk to the cell site. The cell site talks to many mobiles at once, using one channel per mobile. Channels use a pair of frequencies for communication. One for transmitting from the cell site, the forward link, and one frequency for the cell site to receive calls from the users, the reverse link. Communication between mobile units can be either half-duplex or full-duplex. In case of half-duplex, transmit and receive communications between the mobile units are not at the same time, i.e. tal ....etc

Abstract
When English inventor Richard Trevithick introduced the steam locomotive on 21 February 1804 in Wales, it achieved a speed of 8 km/h (5 mph). In 1815, Englishman George Stephenson built the world's first workable steam locomotive.

In 1825, he introduced the first passenger train, which steamed along at 25 km/h (16 mph). Today, trains can fly down the tracks at 500 km/h (311 mph). And fly they do, not touching the tracks.

There is no defined speed at which you can call a train a high speed train but trains running at and above150 km/h ....etc
