Pulse Based Dead Time Compensator for PWM Voltage Inverters



I. Introduction
The state of the art in motor control provides an adjustable
voltage and frequency to the terminals of the motor
through a pulse width modulated (PWM) voltage source inverter
drive. As the power devices change switching states,
a dead time exists. Although the dead time is short, it
causes deviations from the desired fundamental output voltage.
While each deviation does not appreciably affect the
fundamental voltage, the ac ....etc

Randomized Protocols for Duplicate Elimination in Peer-to-Peer Storage Systems



INTRODUCTION

PEER-TO-PEER systems have emerged as cost-effective alternatives
for scalable data sharing, backup, and archival
storage , . Peers contribute data and storage and, in
return, gain access to data at other peers. Effective storage
management is an important issue in the deployment of such
systems. Data replication and caching are key enabling
techniques for scalability, perform ....etc

Switch Architecture Guaranteeing QoS Provision and HOL Blocking Elimination

Abstract

QoS support and congestion management techniques become essential to achieve good network performance in current high-speed interconnection networks.
The most effective techniques traditionally considered for both issues, however, require too many resources for being implemented.
In this paper we propose new cost-effective switch architecture able to face the challenges of congestion management and, at the same time, to provide QoS.
The efficiency of o ....etc
