In this paper, we propose a novel approach to fault simulation of large mixed signal circuits using circuit partitioning and fault ordering. The conventional statistical fault model is divided, to separately account for global and local variations. We consider the problem of estimating the e ect of a parameter deviation in a sub-module, on the system level speci cations for a general non-linear...

Background: Once COVID-19 is transmitted, the corresponding civil responsibility should be clarified by the identification of the transmitter, compensation of the damage and detection of the causal relationship between the damage or harm and the harmful act.    Methods: This research has been prepared by descriptive analytical method and its data has been collected by documentary library tools...

A new approach for protection of power transformer is presented using a time-frequency transform known as Wavelet transform. Different operating conditions such as inrush, Normal, load, External fault and internal fault current are sampled and processed to obtain wavelet coefficients. Different Operating conditions provide variation in wavelet coefficients. Features like energy and Standard dev...

--Due to the overall increase in computer performance software-implemented fault injection (SWIFI) techniques are becoming increasingly attractive. Not only the easyness of use but also the quality of the injected faults contribute to the successful application of SWIFI based tools in the field. SWIFLER is a tool for UNIX systems for sofware-implemented injection of control flow errors. Its pur...

This paper presents a Design-for-Test (DfT) approach for folded ADCs. A sensor DfT circuit is designed to sample several internal ADC test points at the same time, so that, by computing the relative deviation among them the presence of defects can be detected. A fault evaluation is done considering a behavioral model to compare the coverage of the proposed test approach with a functional test. ...

This work evaluates the ability of OBT for detecting parametric faults in continuous-time filters. To this end, we adopt two filters with quite different topologies as cases of study and a previously reported statistical fault model. In addition, we explore the behavior of the test schemes when a particular test condition is changed. The new data reported here, obtained from a fault simulation ...

An airport surface multilateration system based on the time difference of arrival (TDOA) positioning principle establishes equations to calculate the position of target through utilizing the TDOA of targets’ answering signals to the ground receiving stations. The fault with any ground receiving station will result in a significant measuring error of signal’s arrival time and have a lethal impac...

Grid Computing allows coordinated and controlled resource sharing and problem solving in multi-institutional, dynamic virtual organizations. Moreover, fault tolerance and task scheduling is an important issue for large scale computational grid because of its unreliable nature of grid resources. Commonly exploited techniques to realize fault tolerance is periodic Checkpointing that periodically ...

We perform 2-D simulations of earthquakes on rough faults in media with random heterogeneities (with von Karman distribution) to study the effects of geometric and material heterogeneity on the rupture process and resulting high-frequency ground motions in the near-fault region (out to ∼20 km). Variations in slip and rupture velocity can arise from material heterogeneity alone but are dominantl...

This paper proposes a simple and efficient model for designers to estimate fault coverage for partially testuble MCMs. This model relates fault coverage, test methodology. and the ratio and distribution of DFT dies (dies with design for testability features) in an MCM. Experimental results show that our model can eflciently predict the fault coverage of a partially testable MCM with less than 5...
