Abstract

For numerous motion control applications, the limiting factor in the design of the motion device is a highly accurate and quick response. To achieve these performance characteristics, two approaches to the design are possible. The first focuses on the physical construction of the motion device, which includes increasing the mass and thus the rigidity of the system, as well as employing high-precision components. The second procedure addresses the software required to operate and control the system. By combining several advanced cont ....etc

ABSTRACT
This dissertation proposes simple and efficient control algorithms for seismically excited structures using MR dampers and a smart passive system based on MR dampers. Magnetorheological (MR) dampers are one of the most promising control devices for civil engineering applications to earthquake hazard mitigation, because they have many advantages such as small power requirement, reliability, and low price to manufacture. A number of control algorithms have been adopted for semi active systems including the M ....etc

When reference signal for the FxLMS algorithm is taken from an acoustic sensor convergence can be very slow due to great eigen value spread. Using a non acoustic sensor, Such as a tachometer, cancellation of narrow band noise in the sensed fundamental frequency and harmonically related ones can be achieved very fast, although other periodic noises and underline broad band noise will remain.

In this technical paper we present a study of the various routing algorithms, which are in use presently. This study of present algorithms is limited to their general working and the various security problems, which they are unable to solve. Our main emphasis is on discussing a novel approach based on Leap-Frog cryptographic signing protocol and that how this novel approach deals the various security threats, which, its predecessors (using traditional public-key signature schemes) are unable to withstand.
