In a high-resolution small-scale seismic experiment we investigated the shallow structure of the Wadi Araba fault (WAF), the principal fault strand of the Dead Sea Transform System between the Gulf of Aqaba/Eilat and the Dead Sea. The experiment consisted of 8 sub-parallel 1 km long seismic lines crossing the WAF. The recording station spacing was 5 m and the source point distance was 20 m. The...

We consider routing in multiple-bus systems with faulty nodes and buses. A cube-based multiple-bus system is used as an example to demonstrate our approach. In such a system, processors are partitioned into two sets based on the bipartite graph definition, one set is called a processor set and the other one becomes a bus set. A fault-tolerant routing scheme is proposed based on limited global i...

[1] We use numerical simulations to investigate how fault zone dilatancy and pore fluid decompression influence fault strength and friction constitutive behavior. Dilatant hardening can change the frictional response and the effective critical stiffness, Kcr, which determines the transition from stable to unstable sliding in velocity weakening fault zones. We study the frictional shear strength...

Groundwater resource is a very important water resource that has stable temperature, clear, tidy and confident. In recent years, population growth, industrialize and need to food and water, have exposed the groundwater resource on the risk. Reduction of water resources is a main problem in throughout the world. In this research groundwater potential mapping was obtained in Norabad plain, Lorest...

Protecting transmission lines is one important task to safeguard electric power systems. The transient fault signal on transmission lines need to be detected, classified and located accurately and cleared as fast as possible. This research present an application of a discrete wavelet transforms (DWT) for fault diagnosis in underground cable system. Fault simulations are carried out using ATP/EM...

Models of neural networks are developed from a biological point of view. Small networks are analysed using techniques from dynamical systems. The behaviour of spatially and temporally organized neural fields is then discussed from the point of view of pattern formation. Bifurcation methods, analytic solutions and perturbation methods are applied to these models. 0034-4885/98/040353+78$59.50 c ©...

Transmission lines, among the other electrical power system components, suffer from unexpected failures due to various random causes. These failures interrupt the reliability of the operation of the power system. When unpredicted faults occur protective systems are required to prevent the propagation of these faults and safeguard the system against the abnormal operation resulting from them. Th...
