Abstract
Due to increasing demand for speech communications, efficient techniques in low-rate speech coding are of interest.Here a new compression technique using root cepstral analysis has been proposed. Implementing the proposed method causes the coder to deal with root cepstrum coefficients instead of speech samples. The main idea in using root cepstrum analysis is that some of the trivial coefficients can be ignored to send toward the decoder. Thus considerable reduction in the total bit-rate is achieved. Moreover it has the advanta ....etc

HARMONIC ANALYSIS OF SEPARATELY EXCITED DC MOTOR DRIVES FED BY SINGLE PHASE CONTROLLED RECTIFIER AND PWM RECTIFIER
ABSTRACT
PWM rectifier is an ac to dc power converter which is implemented using power electronic semiconductor switches such as MOSFET, IGBT. Different from diode bridge rectifiers, PWM rectifiers achieve bidirectional power flows,which can be extensively used in battery charger, UPS system, regulated dc voltage source. SCR converters provide low power fac ....etc

SPEED SENSORLESS SEPARATELY EXCITED DC MOTOR DRIVE WITH AN ADAPTIVE OBSERVER


ABSTRACT
This project deals with a speed sensorless separately excited dc motor drive which uses the adaptive observer to estimate the rotor speed. The stability analysis of speed estimation is carried out. The modified feed forward control is integrated with the adaptive observer to simplify the implementation. The design guideline for feedback gain and the speed controller are also given to assure system stability for the entire oper ....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

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 press ....etc
