This paper presents a new Fast Kurtogram Method in the time-frequency domain using novel types of statistical features instead of the kurtosis. For this study, the problem of four classes for Bearing Fault Detection is investigated using various statistical features. This research is conducted in four stages. At first, the stability of each feature for each fault mode is investigated. Then, res...

Replication is a suitable approach for the provision of fault tolerance and load balancing in distributed systems. Object replication takes place on the basis of well-designed interaction protocols that preserve object state consistency in an application transparent manner. The published analytic performance models may only be applied in single-server process replication schemes and are not sui...

In this paper, we consider a load-balancing process allocation method for fault-tolerant multicomputer systems that balances the load before as well as after faults start to degrade the performance of the system. In order to be able to tolerate a single fault, each process (primary process) is duplicated (i.e., has a backup process). The backup process executes on a diierent processor from the ...

In this paper a novel pulse sequence testing methodology is presented [22] as an alternative to Time Domain Reflectometry (TDR) for transmission line health condition monitoring, faultfinding and location. This scheme uses Pseudo Random Binary Sequence (PRBS) injection for transmission line testing and fault location with cross correlation (CCR) techniques to build a unique response profile, as...

Abstract Due to the limitations of railway route selection, some high-speed railways are inevitably built near or across fault zones. To study distribution rail-bridge interaction under different load history states suspension bridges three types near-fault pulse-type earthquakes, this paper takes China's longest bridge—Wufengshan Yangtze River Bridge as background and establishes a spatial mod...

This paper presents an efficient and fault-tolerant distributed approach to monitoring the status of processors in a network. The Distributed System Monitor (DSMon) is a distributed, decentralized program that gathers processor information, such as CPU load, user information, and network and disk statistics, in parallel at each processor and reliably distributes the information on-line to all f...

rotating machines in particular induction electrical machines are important industry instruments. in manufacturing, electrical motors are exposed to many damages, and this causes stators and rotors not to work correctly. in this paper we addressed modal analysis and an intelligent method to detect motor load condition and also the stator faults such as turn-to-turn and coil-to-coil faults using...

This paper discusses a novel method for motor fault detection under varying load conditions. Winding Function Approach (WFA) is used to develop a mathematical model to provide indication references for parameters under different load levels and different fault situations. Broken bar defects reference indexes are developed to assess rotor fault severity based on stator current and rotor speed. S...
