Since the advent of high-performance distributed computing, system designers and end-users have been challenged with identifying and exploiting a communications infrastructure that is optimal for a diverse mix of applications in terms of performance, scalability, cost, wiring complexity, protocol maturity, versatility, etc. Today, the span of interconnect options for a cluster typically ranges ...

Long time evolution (LTE) represents an emerging and promising technology for providing broadband, mobile Internet access. Because of the limitation of available spectrum resource, high spectrum efficiency technologies such as channel-aware scheduling need to be explored. In this work, we evaluate the performance of three scheduling algorithms proposed for LTE downlink transmission. The evaluat...

This paper presents a comparative study of different redundant binary full adders (Plus-Plus-Minus (PPM) adder). These PPM adders are simulated to evaluate their performance in total power dissipation, speed and PDP. The performances of these circuits are based on 180nm process model at a supply voltage of 1.8V. We also proposed a new design for PPM adder using 13-transistors. The simulation re...

How social comparative information and specific, proximal goals influence children's skillful performance and percepts of self-efficacy in the context of arithmetic competency development was explored. Low-achieving children in arithmetic received instruction in division and practice opportunities. One group was provided with social comparative information indicating the average number of probl...

Connection Admission Control (CAC) is one of the primary mechanisms for preventive congestion control and bandwidth allocation in ATM networks. A substantial number of CAC schemes have been proposed. In this paper, we review the salient features of some of these algorithms. We also provide a comparative study of the performance of CAC schemes devised to meet certain quality of service requireme...

This paper analyzes the relationship between the comparative advantages of bank branches and the trade area environment. Bank branches are points of sale whose trade environment influences their activities and performance. Comparative advantages are defined, for each output mix, by the strict dominance of a production technology in a specific trade area over the production technologies of other...

This Paper has used a multisectoral input-output model of Iranian economy to examine the ability of different sectors of economy to create jobs per unit of output as well as capital. The results reveal that there is no conflict in a growth strategy that simultaneously attempts to improve efficiency i.e. reallocating production to sectors with low DRCs, equity and job creation. Although sectoral...

A Mobile Adhoc Network is a multihop self-configuring network without any fixed infrastructure of wirelessly connected devices. Due to node mobility and, dynamic topology, designing and implementing reliable routing in MANET is a major challenge. This paper provides the comparative performance analysis of DSR, AODV and DSDV. Different types of test scenarios have been designed with fixed number...
