Electric motors used for traction purposes in electric vehicles (EVs) must meet several requirements, including high efficiency, high power density and faulttolerance. Among them, permanent magnet synchronous motors (PMSMs) highlight. Especially, five-phase axial flux permanent magnet (AFPM) synchronous motors are particularly suitable for in-wheel applications with enhanced fault-tolerant capa...

The use of fault-tolerance structures in multiple processors systems due to the fact that it is almost impossible to manufacture integrated circuits without any defect in nanometer technologies [1]. As a result, the use of fault tolerant methods is crucial to allow that circuits with some amount of defects still reach the market, increasing yield and the lifetime of a chip. A classical example ...

considering recent developments in earthquake engineering, researchers has detected different effects of earthquakes far and near from the fault. investigations that have been done in this area show that near fault earthquakes have shorter time period comparing far fault earthquakes and in the velocity of near fault earthquakes, there are one or more impacting pulses with a big domain and perio...

One of the most important parameters that control reliability growth is the fault exposure ratio (FER) identi ed by Musa et al. It represents the average detectability of the faults in software. Other parameters that control reliability growth are software size and execution speed of the processor which are both easily evaluated. The fault exposure ratio thus presents a key challenge in our que...

Fault detection and failure prediction for nonlinear non-Gaussian systems is an important issue both from the economic and safety point of view. Most of the fault detection techniques assume the system model to be linear and the noise to be Gaussian. These linearization assumptions tend to suffer form poor detection and imprecise prediction. Also, they may lead to false alarms which would incur...

The reliability of Very Large Scale Integration (VLSI) circuits has become increasingly susceptible to transient faults induced by environmental noise with the scaling of technology. Some commonly used fault tolerance strategies require statistical methods to accurately estimate the fault rate in different parts of the logic circuit, and Monte Carlo (MC) simulation is often applied to complete ...

This paper proposes a new linear fault-tolerant permanent-magnet (PM) vernier (LFTPMV) machine, which can offer high thrust by using the magnetic gear effect. Both PMs and windings of the proposed machine are on short mover, while the long stator is only manufactured from iron. Hence, the proposed machine is very suitable for long stroke system applications. The key of this machine is that the ...

Quantum-dot cellular automata (QCA) is a newly-developed nanotechnology for next-generation nanoelectronic circuits. QCA circuits use the propagation of charge polarity in QCA cells to pass information without any current being involved. It has the advantages of extremely small size, low power consumption, high device density and twinkling operation process. Nanofabrication of QCA circuits may ...

A new geometric approach to the a ne geometry of curves in the plane and a ne-invariant curve shortening is presented. We describe methods of approximating the a ne curvature with discrete nite di erence approximations, based on a general theory of approximating di erential invariants of Lie group actions by joint invariants. Applications to computer vision are indicated. y Supported in Part by...

this paper presents a new observer design methodology for a time varying actuator fault estimation. a new linear matrix inequality (lmi) design algorithm is developed to tackle the limitations (e.g. equality constraint and robustness problems) of the well known so called fast adaptive fault estimation observer (fafe). the fafe is capable of estimating a wide range of time-varying actuator fault...
