hello sir or madam,
i m studying b.e. mechanical engineering.i m goin to do a project on the topic automatic solar tracking system using helical gears and stepper motor.i want any idea about this solar tracking system mainly designing gears.i m awaiting for your reply.
thanking you,

As solar power becomes a bigger and bigger part of the overall energy landscape, engineers around the world are busy working out how to build plants that are large and efficient enough to keep up with demand. Now Japanese electronics giant Kyocera is starting construction on what it says will be the largest floating solar power plant (in terms of overall capacity) in the world.

It's the fourth such floating plant Kyocera has worked on so far, but this one promises to be the most impressive yet: the facility is going to be built on the Yamaku ....etc

Abstract

Solar Panel Maximum Power Point Tracker . As the name implied, it is a photovoltaic system that uses the photovoltaic array as a source of electrical power supply and since every photovoltaic (PV) array has an optimum operating point, called the maximum power point, which varies depending on cell temperature, the insolation level and array voltage. A maximum power point tracker (MPPT) is needed to operate the PV array at its maximum power point ....etc

Extracting useable electricity from the sun was made possible by the discovery of the photoelectric mechanism and subsequent development of the solar cell a semi conductive material that converts visible light into a direct current. By using solar arrays, a series of solar cells electrically connected, a DC voltage is generated which can be physically used on a load. Solar arrays or panels are being used increasingly in remote areas where placement of electricity lines is not economically viable.

Light gathering is dependent on the angle of ....etc

Abstract
We demonstrate how 1-of-n encoded speed-independent
circuits provide a good framework for constructing smart
card functions that are resistant to side channel attacks
and fault injection. A novel alarm propagation technique
is also introduced. These techniques have been used to
produce a prototype smart card chip: a 16-bit secure
processor with Montgomery modular exponentiator and
smart card UART.
1. Introduction
Smart cards are increasingly prevalent, particularly in
Europe, for authentication and payment mech ....etc

Design and implementation of a novel
high-performance sensorless control system
for interior permanent magnet
synchronous motors

J.-L. Chen T.-H. Liu C.-L. Chen



Abstract:
This study proposes a novel high-performance rotor position estimator for an interior permanent magnet synchronous motor (PMSM). By suitably processing the mathematical model of the motor, a systematic method of the rotor position estimating method has been developed. The proposed control system can be used in the space ....etc
