[1] We model ruptures on faults that weaken in response to flash heating of microscopic asperity contacts (within a rate-and-state framework) and thermal pressurization of pore fluid. These are arguably the primary weakening mechanisms on mature faults at coseismic slip rates, at least prior to large slip accumulation. Ruptures on strongly rate-weakening faults take the form of slip pulses or c...

Two-dimensional, numerical models of a linear fault embedded within a linear elastic medium show the generation of off-fault tensile failure that results from inelastic slip along the fault. We explore quasistatic models with slip-weakening friction to assess the effects of spatially and temporally variable friction on the damage patterns. Tensile fractures form where tangential normal stresses...

Motorcycles generate dissimilar sound patterns under different working conditions. Generally, the experienced mechanics in authorized service stations take test rides to hear the sounds produced to diagnose the faults. The presented work attempts to locate the faults in motorcycles based on the sound. The features are extracted using pseudospectra of sound signals. Integration is performed for ...

nowadays urban sanitary landfill compatible with environmental principles and in line with sustainable development is a necessity. in this paper for the purpose of determining appropriate sanitary landfill sites in kohgilooye & boyerahmad province, , many data layers were used including: slope, land cover, distance to main roads, distance to cities & villages, geology, surface water network, di...

In this paper, we present adaptive fault-tolerant deadlock-free routing algorithms for hypercubes and meshes by using only 3 virtual channels and 2 virtual channels respectively. Based on the concept of unsafe nodes, we design a routing algorithm for hypercubes that can tolerate at least n 1 node faults and can route a message via a path of length no more than the Hamming distance between the s...

Short-circuit calculations are extremely important in the application and setting of protective relays and the analysis of power system operations. This paper illustrates the calculation of fault currents and voltages during intermediate faults in underground cables, taking into consideration the cable sheath bonding and grounding method. The compensated ground loop impedance for faults along t...

the main purpose of this study is landslide hazard assessment the ziarat watershed (golestan province) using information value and lnrf models within geographic information. at first stage, a landslide inventory map was prepared in the study area using earlier reports and aerial photographs, and a total of 50 landslides was mapped and out of which 35 (70%) were randomly selected for building la...

In this paper, a new idea in machinery fault diagnostic by combining minimum-distance pattern-recognition and discrete wavelet transform (DWT) is presented. The method starts by forming the feature vector, which is basically the position vector of a point in the hyperspace spanned by the set of wavelet coefficients. These coefficients are obtained by expanding the measured signal from faulty ma...

Thefaults in the underground cables cause to generatetransients which propagate along power cable as travelling waves. The velocity of generated wave and time taken by a reach source point from fault location enables us calculate distance value.In this paper double endedtravelling based approach is used communication channel designed distance. A circuit-based model developed EMTP-RV software fi...
