This paper investigates the fault detection of a micro parallel plate capacitor subjected to nonlinear electrostatic force. For this end Thau observer, which has good ability in fault detection of nonlinear system has been presented and governing nonlinear dynamic equation of the capacitor has been presented. Upper and lower threshold for fault detection have been obtained. The robustness of th...

This article proposes a novel transient 3-D lumped-parameter (LP) thermal model and finite-element (FE) of triple redundant nine-phase permanent magnet-assisted synchronous reluctance machine to predict the asymmetric temperature distribution under various fault conditions. First, predicted steady-state temperatures are compared between LP FE models conditions with uneven loss distribution. Als...

during past earthquakes, many instances of building damage as a result of earthquake surface fault rupture have been observed. the results of investigating a potential mitigation scheme are presented in this paper. such plan provides a wall in the soil with the aim of surface displacement localization in the narrow pre-determined location. this may reduce the risk of the future rupture downstre...

This paper examines downward price rigidity in Iranian house market and discusses whether this characteristic would result in an asymmetric relationship between house price and monetary policy. To test the downward house price rigidity the threshold GARCH model is employed. The asymmetric adjustment to monetary policy is examined using the asymmetric cointegration and error correction models. T...

credence goods market is one of the markets that the asymmetric information has transformed it to a missing market. those goods and services that the applicant cannot determine the exact amount of their expenses due to the asymmetric information are called credence goods. from the economists' perspective, transaction in a market where participants are ignorant about each other is a game wi...

Field observations of the incurred damages to the buildings and bridges due to earthquakes in near field show there are various failure modes which are in relation to the forces caused by vertical component. While vertical component of earthquake for ordinary buildings in most seismic regulations and standards is not considered. Therefore, in the current study the effects of vertical and horizo...

Abstract We study how the asymmetric geometry of thrust faults affects dynamics supershear ruptures and their associated trailing Rayleigh as they interact with free surface, investigate resulting near‐field ground motions. Earthquakes are mimicked by propagating laboratory along a frictional interface 61° dip angle. Using an experimental technique that combines ultrahigh‐speed photography digi...

Mars' surface exhibits abundant topographic expressions of large thrust fault-related folds that have been attributed to global planetary contraction. Morphometric analyses such structures provide insight into their growth history. With THEMIS imagery and HRSC–MOLA data, 49 thrusts with lengths between 35 544 km were mapped across surface. Assuming planar fault geometries dips 30°, the average ...

This paper presents a method for diagnosis of eccentricity fault in a switched-reluctance motor (SRM) during offline and standstill modes. In this method, the fault signature is differential induced voltage (DIV) achieved by injecting diagnostic pulses to the motor windings. It will be demonstrated by means of results that there is a correlation between differential induced voltage and eccentri...
