A dynamic programming-based optimization strategy for a temporal decomposition (TD) model of speech and its application to low-rate speech coding in storage and broadcasting is presented. In previous work with the spectral stability-based event localizing (SBEL) TD algorithm, the event localization was performed based on a spectral stability criterion. Although this approach gave reasonably goo...

In this paper combination of a load-commutated inverter (LCI) and a voltage-source inverter (VSI) are employed for performance analysis of induction motor drive. Performance of the drive has been evaluated through the different variation in reference speed and load torque. proposed LCI-based induction motor drives include the following Advantages: 1) sinusoidal motor phase current and voltage b...

The choice of the CMOS logic to be used for implementation of a given specification is usually dependent on the optimization and the performance constraints that the finished chip is required to meet. This paper presents a comparative study of CMOS static and dynamic logic. Effect of voltage variation on power and delay of static and dynamic CMOS logic styles studied. The performance of static ...

A dynamic element matching approach to ADC testing is presented. With this technique a highly nonideal DAC is used to generate an excitation for the DUT. Dynamic element matching is used to create a statically precise excitation from imprecise components. Simulation results show this approach can be used to accurately measure the performance of an ADC. This technique offers potential for use in...

This paper presents the dynamic characteristics of the transverse flux linear motor (TFLM) with permanent magnet (PM) excitation, which has E-shaped core. Because of the inherent feature of TFLM with PM excitation that the flux flow path is threedimension, the solid type stators and mover cores are used. In case of adoption of solid type stators and mover cores, as the motor speed is increased,...

additional dampers are employed in order to decrease the dynamic response of structure against the earthquake and wind loading recently. in this study, two types of systems related to waste of inactive energy, i.e. frictional damper which is categorized in dampers dependent on movement and viscoelastic damper which is categorized in dampers dependent on velocity, in making steel structures resi...

this study is investigated the optimum parameters for a tuned mass damper (tmd) under the seismic excitation. shuffled complex evolution (sce) is a meta-heuristic optimization method which is used to find the optimum damping and tuning frequency ratio for a tmd. the efficiency of the tmd is evaluated by decreasing the structural displacement dynamic magnification factor (ddmf) and acceleration ...
