in this study, the development of structural elements and the relationship between these elements and dikes emplacements investigated by the field surveys and analysis of satellite images of the east dasht-e bayaz fault zone. in this area nnw-sse (t2) and nw-se trending dikes are which follow the fractures of the region. we measured geometric characters of dikes (such as thickness, attitude, di...

the nw-se trending tus fault is one of the active faults in the north-east of iran . geomorphologic evidences indicate that this fault is active and goes through mashhad city from near tus town. since the population and number of pilgrims in this city are high, the study of the tus fault is of great importance. hence, we have carried out a new investigation to evaluate the hazardous potential o...

Wireless sensor nodes can experience faults during deployment either due to its hardware malfunctioning or software failure or even harsh environmental factors and battery failure. This results into presence of anomalies in their time-series collected data. So, these anomalies demand for reliable detection strategies to support in long term and/or in large scale WSN deployments. These data of p...

Low stacking fault energy face centered cubic (FCC) materials contain characteristic defect structures. Stacking fault tetrahedral are one of those rare structures that occur under special experimental conditions. For the first time, stacking fault tetrahedral were observed in Fe-30Mn-3Al-3Si twinning induced plasticity (TWIP) steel. Their presence resulted from a quenching heat treatment.

Effects of radiation on electronic circuits used in extra-terrestrial applications and radiation prone environments need to be corrected. Since FPGAs offer flexibility, the effects of radiation on them need to be studied and robust methods of fault tolerance need to be devised. In this paper a new fault-tolerant design strategy has been presented. This strategy exploits the relation between cha...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract In Wireless Sensor Networks (WSN’s) fault tolerance is one of the most important critical issues. The difficulty of missing communication link, Node and data are ineluctably foreordained in WSN’s and due to assorted factors such as power drain, env...

Robust features are very critical to track the degradation process of a gear. They are key factors for implementing fault diagnosis and prognosis. This has driven the need in research for extracting good features. This paper used a new method, Narrowband Interference Cancellation, to suppress the narrow band component and enhance the impulsive component enabling the gear fault detection easier....

The three-phase shift between line current and phase voltage of induction motors can be used as an efficient fault indicator to detect and locate inter-turn stator short-circuit (ITSC) fault. However, unbalanced supply voltage is one of the contributing factors that inevitably affect stator currents and therefore the three-phase shift. Thus, it is necessary to propose a method that is able to i...
