Since the very early days of electronic components failures have continuously been appearing. In spite of enormous development and production improvements this situation has not changed. Even automated equipment faults continue to be created on circuit boards. There is not a single manufacturing technique that will guarantee the 100 percent fault free circuit board. Each new technology creates ...

Under the background of the deficiencies and shortcomings in traditional diesel engine fault diagnostic, the naïve Bayesian classifier method which built on the basis of the probability density function is adopted to diagnose the fault of diesel engine. A new approach is proposed to weight the super-parent one dependence estimators. To verify the validity of the proposed method, the experiments...

This paper presents a design approach for implementing fault-tolerant embedded computing nodes in spacecraft using non-hardened, commodity microcontrollers. The approach uses faulttolerance to address high rate transient errors and occasional latch ups that are expected of such devices in the space radiation environment. A key constraint is to minimize the amount of external logic needed to sup...

This paper discusses the suitability of four-phase, five-phase, and six-phase modular machines, for use in applications where servo characteristics and fault tolerance are key requirements. It is shown that an optimum slot number and pole number combination exists, for which excellent servo characteristics could be achieved, under healthy operating conditions, with minimum effects on the power ...

Fault-tolerant communication and energy efficiency are important requirements for future-generation wireless ad hoc networks, which are increasingly being considered also for critical application domains like embedded systems in automotive and aerospace. Topology control, which enables multi-hop communication between any two network nodes via a suitably constructed overlay network, is the prima...

Amajor difficulty in inverting geodetic data for fault slip distribution is that measurement errors are mapped from the data space onto the solution space. The amplitude of this mapping is sensitive to the condition number of the inverse problem, i.e., the ratio between the largest and smallest singular value of the forward matrix. Thus, unless the problem is wellconditioned, slip inversions ca...

Flux coupling in heteropolar magnetic bearings permits remaining active coils to assume actions of failed coils to produce force resultants identical to the un-failed actuator. This fault-tolerant control usually reduces load capacity because the redistribution of the magnetic flux which compensates for the failed coils leads to premature saturation in the stator or journal. A distribution matr...

The application of flat superconductor rings has been investigated in the structure of inductive shieldtype high temperature superconducting fault current limiters, HTc-SFCL. A laboratory scale inductive shield-type HTc-SFCL has been designed and fabricated using flat superconductor rings. The fabrication process has been fully presented. YBCO powder has been used for the fabrication of superco...

-The area of the digital image processing is getting more attention in the hope that it will increase the accuracy of any scientific measurements. One of many digital image processing applications is texture analysis. Fabric or cloth is a flexible artificial material that is made by a network of natural or artificial fibers. Fabric fault inspection is an important process in the textile industr...

The characteristics of near-fault ground motion are investigated considering heterogeneous slip distribution on the fault plane. Areas on the fault plane with large slip in compare with the average slip on the fault are known as asperity. The characteristics of strong ground motions in near-fault area are strongly affected by faulting parameters such as asperity location, maximum slip of asperi...
