This paper addresses the problem of evaluating the effectiveness of test sets to detect crosstalk defects in system-level interconnects and buses of deep submicron (DSM) chips. The fast and accurate estimation technique will enable: 1) evaluation of different existing tests, like functional, scan, logic built-in self-test (BIST), and delay tests, for effective testing of crosstalk defects in co...

In this paper, sensor fault diagnosis and tolerant control strategy are investigated for quadcopters under faults disturbances. We propose the estimation system fault-tolerant (FTC) method.

This paper addresses the problem of robust fault estimation and fault tolerant control of a continuous age structured model of a harvested fishery system. The harvested fish population is represented by TakagiSugeno fuzzy systems, where the effort is used as a control term, the age classes as a states and the quantity of captured fish per unit of effort as a measured output. Under some biologic...

Abstract - Use of efficient signal processing tools (SPTs) to extract proper indices for fault detection in induction motors (IMs) is the essential part of any fault recognition procedure. The Part1 of the two parts paper focuses on Fourier-based techniques including fast Fourier transform and short time Fourier transform. In this paper, all utilized SPTs which have been employed for fault fete...

Recently, State of energy (SOE) has become one of the most fundamental parameters for battery management systems in electric vehicles. However, current information is critical in SOE estimation and current sensor is usually utilized to obtain the latest current information. However, if the current sensor fails, the SOE estimation may be confronted with large error. Therefore, this paper attempt...

This paper presents an improved estimation technique for hybrid BIST test set generation. In a hybrid BIST approach the test set is assembled from pseudorandom and deterministic test patterns. The efficiency of the hybrid BIST approach is determined by the ratio of those test patterns in the final test set. Unfortunately, exact algorithms for finding the optimal test sets are computationally ve...

In this work, a new active fault tolerant control (FTC) is developed for an unmanned bicycle robot based on integration between sliding mode (SMC), detection (FD), and estimation (FE) via residual signal.

In this paper a new method for determining the search area for motion estimation algorithm based on block matching is suggested. In the proposed method the search area is adaptively found for each block of a frame. This search area is similar to that of the full search (FS) algorithm but smaller for most blocks of a frame. Therefore, the proposed algorithm is analogous to FS in terms of reg...

Reliability is one of the fundamental considerations in the design of industrial control equipment.
