Lali sub-surface structure, with a NW-SE Zagros trending is located in Dezful Embayment. To determine the folding mechanism, structural geometric parameters including limbs dip, amplitude, wavelength, and crestal length were determined in four stages during deformation. In order to investigate the lateral folding mechanism, these geometric parameters were analyzed in three parts in the Lal...

This paper presents some results that were obtained in fault diagnosis for a wood-drying process. It is diffcult to detect and diagnose faults or failure in the drying process due to complex dynamic nonlinearity, coupling effects among key variables, and process disturbances caused by the variation of lumber sizes, species and environmental factors. In this paper, a real-time fault diagnosis al...

This paper presents the impact study of apparent reactance injected by series Flexible AC Transmission System (FACTS) i.e. Thyristor Controlled Series Reactor (TCSR) on the measured impedance of a 400 kV single electrical transmission line in the presence of phase to earth fault with fault resistance. The study deals with an electrical transmission line of Eastern Algerian transmission networks...

An approach to test optimization in switched-capacitor systems based on fault simulation at switch-level is presented in this paper. The advantage of fault simulation at this granularity level is that it facilitates test integration as early as possible in the design of these systems. Due to their mixed-signal nature, both catastrophic and parametric faults must indeed be considered for test op...

Modern manufacturing facilities are large scale, highly complex, and operate with large number of variables under closed loop control. Early and accurate fault detection and diagnosis for these plants can minimise down time, increase the safety of plant operations, and reduce manufacturing costs. Fault detection and isolation is more complex particularly in the case of the faulty analog control...

Localized defects in rotating mechanical parts tend to result in impulse response in vibration signal, which contain important information about system dynamics being analyzed. Thus, parameter identification of impulse response provides a potential approach for localized fault diagnosis. A method combining the Morlet wavelet and correlation filtering, named Cyclic Morlet Wavelet Correlation Fil...

This paper presents a fault diagnosis method for a centrifugal pump system with frequency-domain symptom parameters by using the wavelet transform, rough sets and a fuzzy neural network to detect faults and distinguish fault types at an early stage. The wavelet transform is used for feature extraction across an optimum frequency region. The diagnosis knowledge for the training of neural network...

Teleseismic body waveform modeling of the far-field P-and SH-waveforms and spectral analysis of P-waves are used to determine the source parameters of the March 25, 2006 Fin earthquake (mb 5.7). Its epicenter is located at the South of Iran in Hormozgan Province. The waveform modeling results show the earthquake was caused by a thrust motion on a NW-SE striking fault with parameters: Fault plan...

Genetic algorithms have proven to be a viable solution to the NP-complete problem of test vector generation. However, the parameters used to control GA-based ATPG can greatly affect test set size, fault coverage, and CPU execution time. Knowing how a given set of parameters will affect each of these factors a priori allows for more efficient testing procedures. Over 1 million ATPG experiments w...
