An accurate fault detection, classification and direction estimation of double end fed transmission lines based on application of artificial neural networks is presented in this paper. The proposed method uses the phase voltage and current available at only the local end of line. This method is adaptive to the variation of fault inception angle, fault location and high fault resistance. The alg...

Kuhbanan fault system, as one of the intracontinental faults of central Iran, is recognized by considerable seismogenic activities and modern morphotectonics evidences with a strike-slip (reverse component) motion. According to the geometric and kinematics data, Kuhbanan fault has been divided into 5 segments (S26, S27, S28, S29, S30) in Bahabad region. Measured geomorphic indices of ratio of v...

In this paper, we propose a new technique that uses fault injection to reverse-engineer a private block cipher implemented with an unknown S-box. The private algorithm we wish to retrieve differs from a known algorithm in the choice of the S-Box, which we find using a novel, fault-injecting technique. The main idea is to consider the components of the S-Box as the solutions of a linear boolean ...

Power plant generators are important components of an electrical energy system. They should be constantly monitored and protected in order to maintain the quality and reliability of the power supply. Otherwise, generators may occur in case of faults or incorrect operation. One of them is reverse power condition. Reverse power flow can be cause important problems if it is not considered in the p...

The three notorious earthquakes of 1999 in Turkey Kocaeli and Düzce and Taiwan Chi-Chi , having offered numerous examples of surface fault rupturing underneath civil engineering structures, prompted increased interest in the subject. This paper develops a nonlinear finite-element methodology to study dip–slip “normal” and “reverse” fault rupture propagation through sand. The procedure is verifi...

Neural networks have been shown to be vulnerable against fault injection attacks. These attacks change the physical behavior of device during computation, resulting in a value that is currently being computed. They can realized by various techniques, ranging from clock/voltage glitching application lasers rowhammer. Previous works mostly explored for output misclassification, thus affecting rel...

Near-field co-seismic GPS data were used to derive the slip distribution of the 12 May 2008 Wenchuan earthquake. Based on field measurements and geological observations, the earthquake is represented by ruptures on the Beichuan fault and a neighboring fault from Pengxian to Guanxian, both dipping with a decreasing angle with depth. Using a layered elastic crust model, we obtained a slip model t...

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...

Although strong and damaging earthquakes have hit Zagreb in the past, 22 March 2020 earthquake (Mw 5.4) is first one that was recorded by a modern digital local seismic network, which could be analysed not only macroseismic methods, but also microseismic ones. Herewith we used 3003 carefully located events from year of aftershock sequence to learn more about rate decay, their magnitude distribu...
