Abstract:
A modified friction damper is presented to enhance the performance of conventional friction damper and semi-active variable friction damper. An additional plate is provided between the two sliding plates of a conventional friction damper which results in an additional sliding interface with the same normal (clamping) force. Similar modification is also made to semi-active variable friction damper (SAVFD) to enhance its performance. The enhancement in the performance of the benchmark building is studied under across wind loads ....etc

microcontroller based speed control of separately excited dc motor

Abstract

A PIC microcontroller based closed loop speed control scheme has been developed for the speed control of a separately excited DC motor fed from PV array. An IGBT based boost converter is used as an interface between PV array and the DC motor. The microcontroller has been programmed to automatically vary the duty cycle of the boost converter depending upon the set/required speed of the motor. The DC motor model has been developed and the complete simulink model of the ....etc

Abstract
Drilling assisted by axial vibration at low frequency is a promising machining process because, by naturally fragmenting chips, it can improve both productivity by canceling stripping operations and work piece quality by decreasing negative effects due to chip friction. Based on a theory of self-excited vibrations, a drilling device has been developed which is described in this paper. This technology is very compact and can used on any conventional machine tool. However the experiments on these machine tools are quite difficul ....etc

ABSTRACT
Over the last few years the interest in distributed generation and island operation of small production units has increased. Many of the existing such units are hydro power stations with induction generators. These are not initially constructed for island operation, but with some extra equipment this kind of operation is feasible. In this paper the behavior of two parallel-operated induction generators driven by hydro turbines are studied during load steps. The influence of a STATCOM based voltage regul ....etc

IPPAM within the framework of the project is underway to build a mechatronic prosthesis under equipped with pneumatic artificial muscles. The aim of this PhD project is study of the influence of an actuated prosthesis to a step pattern of leg amputees. The rigidity of the prosthesis only adaptable, and there must be a certain torque can be delivered. Students are first asked to operate with a control panel (displays, knobs, ..) for the prosthesis design. The prosthesis must possess a number of operating modes. It must be possible for the pressu ....etc
