In this study we considered and analyzed the diierent cases of node-and link-faults in a hypercube multiprocessor. We revealed that, the direct use of sharp product operation is not suucient to discard only computational part (processor and memory), when only this part of node is faulty. We also showed that in case when some links in communication part (router) incident to a healthy node are fa...

A protein called NPTX2 may be a useful marker of neural circuit defects in patients with Alzheimer's disease.

This paper presents a comparative study of two distinct modulation strategies applied to a permanent magnet synchronous motor drive, under inverter faulty operating conditions. A rotor field oriented control is used and a performance evaluation is conducted by comparing a hysteresis current control with a space vector modulation technique. Three different operating conditions are considered: no...

Due to industrial importance of gears in power transmission systems, fault detection and diagnosis of gear transmission systems have attracted considerable attention in recent years, there is constant pressure to improve measuring techniques and tools for early detection and diagnosis of gearbox faults. The time and frequency localization properties of continuous wavelet transform offers a viab...

Wavelet transform is a well-known signal processing technique which has proven to be a successful technique in Non-Destructive Testing (NDT). Adopting this technique by Acoustic Emission (AE) method could result in better interpretation of data that are used for fault detection. In this study, AE signals emitted from automobile engines in both faulty and healthy conditions are analyzed using wa...

The paper considers the problem of active fault diagnosis for discrete-time stochastic systems over an infinite time horizon. It is assumed that the switching between a fault-free and finitely many faulty conditions can be modelled by a finite-state Markov chain and the continuous dynamics of the observed system can be described for the fault-free and each faulty condition by non-linear non-Gau...

BACKGROUND A basic analysis of a patient's gait and posture provides information about the body and the capability of the musculoskeletal system to adjust to physical stressors. An understanding of normal gait and posture is essential for identifying and treating musculoskeletal pain. OBJECTIVE This article discusses normal gait and how to assess gait. It also outlines common musculoskeletal ...

This study investigated whether stereotype threat can influence women’s attributions of failure in a computer task. Male and female college-age students (n = 86, 16–21 years old) from Germany were asked to work on a computer task and were hinted beforehand that in this task, either (a) men usually perform better than women do (negative threat condition), or (b) women usually perform better than...

Abstract: This paper deals with the design problem of reliable H� fuzzy switching controllers for continuoustime nonlinear systems with different actuator fault mode. First, the Takagi-Sugeno (T-S) fuzzy model is employed to represent a nonlinear system. Next, based on the fuzzy model, a faulty switched system is constructed to model various classes of faulty nonlinear systems. The objective is...

BACKGROUND The aim of the study was to carry out a complex analysis of loading and overloading of a musician. MATERIALS AND METHODS Eighty students of music school accordion class, and 60 students of colleges, participated in a pilot test. The test estimated the function of hand muscles, the body statics, the body posture, the presence of spinal curvatures, the time of straight reaction, the ...
