Abstract Near-fault ground motions may contain impulse behavior on velocity records. To calculate the probability of occurrence impulsive signals, a large dataset is collected from various national data providers and strong motion databases. The has number parameters which carry information earthquake physics, ruptured faults, parameters, distance between station several parts fault. Relation s...

This article presents an approach to improve and monitor the behavior of a skid-steering rover on rough terrains. An adaptive locomotion control generates speeds references to avoid slipping situations. An enhanced odometry provides a better estimation of the distance travelled. A probabilistic classification procedure provides an evaluation of the locomotion efficiency on-line, with a detectio...

Abstract Data-driven fault detection techniques have attracted extensive attention in engineering, industry and many other areas recent years. In real applications, the following situation often occurs: data for certain types of faults (unseen faults) are not available to train models that used detection. Such a scenario can occur when collection becomes highly time-consuming or destructive. To...

Various approached have been introduced to extract as much as information form seismic image for any specific reservoir or geological study. Modeling of faults and fractures are among the most attracted objects for interpretation in geological study on seismic images that several strategies have been presented for this specific purpose. In this study, we have presented a modified approach of ap...

We describe a time-e cient procedure for removing sequentially redundant faults from synchronous sequential circuits with synchronizing sequences. We use properties of redundant faults and propose several methods to identify subsets of redundant faults that can be removed simultaneously from the circuit. By removing several redundant faults simultaneously, the number of repetitions of the test ...

Catastrophic failures in power grid due to maloperation of traditional backup protection system (e.g. third zone of distance relays) was one of the main causes of many cascade trips. This paper assess a new wide-area backup protection system (WABPS) based on phasor measurement units (PMU), to improve third zone of distance relays to avoid its mal-operation. Based on this assessment, phasor meas...

Some faults in storage elements (SEs) do not manifest as stuck-at0/1 faults. These include data-feedthrough faults that cause the SE cell to exhibit combinational behaviour. The authors investigate the implications of such faults on the behaviour of circuits using unclocked SEs. It is shown that effects of data-feedthrough faults at the behavioural level are different from those due to stuck-at...

By simulating a multi-terminal high voltage DC grid using a detailed electro-magnetic transient simulation model, challenges in fault detection and discrimination are demonstrated. To select the most appropriate signal for fast and reliable detection of faults, behavior of the DC grid during the faults is observed by means of various terminal measurements. By simulating different scenarios, cha...

I revisit the fault-tolerance of cyclic redundancy checks (CRCs), expanding on the work of Driscoll et al [1]. I introduce the concepts of Schrödinger-Hamming weight and Schrödinger-Hamming distance, and I argue that under a fault model in which stuck-at-one-half or slightly-out-of-spec faults dominate, current methods for computing the fault detection of CRCs may be over-optimistic. Keywords-c...
