The main objective of this study is estimating acceleration time history of 16 September 1978 Tabas earthquake incorporating the seismological/geological source-path and site model parameters by using finite-fault simulation approach. The method generalizes the stochastic ground-motion simulation technique, developed for point sources, to the case of finite faults. It subdivides the fault plane...

We review the results of a recent series of papers in which the interaction between a dynamic mode II fracture on a fault plane and off-fault damage has been studied using high-speed photography. In these experiments, fracture damage was created in photoelastic Homalite plates by thermal shock in liquid nitrogen and rupture velocities were measured by imaging fringes at the tips. In this paper ...

The Video-on-Demand (VoD) application is popular as the videos are delivered to the users at anytime and anywhere. The system load is increased due to simultaneous access of VoD system by many users. The proposed architecture discusses load balancing mechanism within a video server and to provide service to the users with small start-up delay. The Video storage is based on the probability of th...

In the last lecture, we talked about how to emulate one network on another by constructing embeddings with low load, congestion and dilation. In this lecture we apply this embedding technique to emulate a fault-free square mesh on a faulty square mesh. Up to certain fault parameters we can achieve embeddings with constant load and congestion and small dilation. This allows us to use the result ...

Recently a great deal of attention has been paid to the design of hierarchical shared memory cluster system. Cluster computing has made hierarchical computing systems increasingly common as target environment for large-scale scientific computations. This paper proposes hierarchical shared memory cluster architecture with load balancing and fault tolerance. Hierarchies of shared memory and cache...

The electric power industry is currently undergoing an unprecedented reform. One of the most exciting and potentially profitable recent developments is increasing usage of artificial intelligence techniques. The intention of this paper is to give an overview of using neural network (NN) techniques in power systems. According to the growth rate of NNs application in some power system subjects, t...

A method for determining the earth fault distance in high impedance grounded networks is presented here. With the transient processes having decayed in case of an earth fault, the grid tunes into a steady state error condition in which it can be operated initially. Starting out from the stationary earth fault condition a line model of a unilaterally powered feeder with one load based on a PI-el...

This paper presents an Adaptive Trusted Fault Tolerance (TFT) scheme with Data Recovery for the prevention of selfish attack in MANET it also prevents the packets drop caused by the buffer overflow of the node. In the proposed technique an adaptive variations in trust certification waiting time is proposed instead of simple TFT schemes, which helps reduces the false identification of nodes duri...

although many mathematics-based and heuristic approaches have been recently developed on optimally allocation of tcscs for lines overloads reduction and buses voltage stability enhancement during fault conditions, the works on the tcscs efficiency to achieve the abovementioned goals are rare. this idea that tcscs can surely enhance the system’s security must be comprehensively investigated. in ...
