the paper presents a mathematical base modeling combined to modified-winding -function-approach (mwfa) for eccentricity fault detection of a round-rotor synchronous machine. for this aim, a 6-pole machine is considered, and the machine inductances are computed by mwfa in healthy and also under eccentricity fault. a numerical discrete-time method has been proposed to machine modeling in voltage-...
We investigate whether productivity differences explain why some manufacturers sell only to the domestic market while others serve foreign markets through exports and/or FDI. When overseas production offers no cost advantages, our model predicts that investors should be more productive than exporters. An extension allowing for low-cost foreign production can reverse this prediction. Data for 10...
We study the relationship between diagnostic test generation for a gate-level fault model, which is used for generating diagnostic test sets for manufacturing defects, and functional test generation for a high-level fault model. In general, a functional fault may partially represent some of the effects of one gate-level fault but not another. Generating a test sequence for the functional fault ...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
In this paper, a new open-switch fault diagnosis method is proposed for the six-phase AC-DC converter based on the difference between the phase current and the corresponding reference using an adaptive threshold. The open-switch faults are detected without any additional equipment and complicated calculations, since the proposed fault detection method is integrated with the controller required ...
A new PMU-based fault detection/location algorithm for multi-terminal transmission lines is proposed in this paper, which works on the basis of synchronized voltage and current phasors received from PMUs installed in various terminals. The Clark transform (for transposed transmission lines), Eigen-values and eigenvectors theory (for un-transposed ones) are used to decouple 3-phase differential ...
As fault tolerance is the ability of a system to perform its function correctly even in the presence of faults. Therefore, different fault tolerance techniques are critical for improving the efficient utilization of expensive resources in high performance data grid systems. One of the most popular strategies of fault tolerance is the replication, it creates multiple copies of resources in the s...
Most conventional software-based approaches for fault tolerant Ethernet (FTE) adopt a heartbeat mechanism for fault detection. However, due to the tradeoff between the number of nodes and the fault detection time, these conventional approaches do not provide scalability for large-scale networks. To solve this scalability issue, we previously proposed the SAFE scheme, which utilizes multiple sub...
This paper develops a new approach to double fault isolation in linear systems with the aid of directional residuals. The method of residual generation for computational as well as internal forms is applied. Isolation of double faults is based on the investigation of the coplanarity of the residual vector with the planes defined by the individual pairs of directional fault vectors. Additionally...
still leaves identifying which LBs are to be reconngured. For fault tolerance , this entails fault detection/location. For yield enhancement, a method for identifying faulty LBs that is transparent to the user is required.
