In Portland Cement Concrete (PCC) pavement of the roads, dowels bar transfers vehicle loading to the unloaded slab. Load Transfer Efficiency (LTE) is used to evaluate dowel bars in PCC pavement. This parameter is defined as the vertical displacement ratio of the loaded slab versus the unloaded slab. In this study, the impact of effective factors (friction coefficient between dowel and concrete ...

This paper introduces mechanisms to correlate contents and priorities of incoming HTTP requests used for server process scheduling with the load balancing policies for Web-server clusters. This approach enables both load balancing and Web quality of service (QoS). Another contribution is a modeling and analysis technique based on stochastic highlevel Petri net methods for QoS-aware load balanci...

in this paper, the performance of two types of facts devices in order to enhance the power system static voltage stability has been investigated. these devices include static var compensator (svc) and thyristor controlled series capacitor (tcsc). the modeling of the single machine infinite bus (smib) and aforesaid devices has been made up in steady state mode with disregarding of the generator ...

Load characteristics are the main factor to affect voltage stability. In addition, load modeling reflecting the actual load characteristics has been a well—known difficult problem and unsolved so far, It is mainly due to the fact that the load composition, amount and characteristics are always changing. This paper introduces the slip into the equivalent impedance load model to analyze load char...

This paper presents a novel distribution power flow algorithm to estimate losses and analyze unbalanced distribution systems. An unbalanced distribution network is decomposed into clusters. The unbalanced laterals are solved using the backward/forward sweep method in each phase. The clustering of total network makes faster computation. The three phase modeling of all the distribution transforme...

Research prototypes of networked systems are often evaluated on overlay testbeds and emulation testbeds. Most of the strengths and weaknesses of these two types of testbeds are complementary. We outline the motivation, design, implementation, and sample results of an environment that seeks to provides the best of each type. Flexlab couples an emulation testbed with arbitrary network models. We ...

Steady-state analysis of a three phase induction motor can be carried out by using computer simulation software such as MATLAB. From Simulink/Power system block set (PSB) library, the induction motor model can be effectively used to simulate the effects of DC resistance, no-load and blocked rotor tests. These tests are performed on a machine to estimate the values of stator and rotor resistance...
