Desmoids are myofibroblastic proliferations occurring in 15% of patients with familial adenomatous polyposis (FAP), 70% being intra-abdominal desmoids (IAD). Since the morbidity and mortality due to desmoids is almost entirely attributable to IAD, we aimed to identify specifically risk factors predicting IAD development in FAP. We undertook a retrospective(More)
= {We present an integrated system for training visceral needle puncture procedures. Our aim is to provide a cost effective and validated training tool that uses actual patient data to enable interventional radiology trainees to learn how to carry out image-guided needle puncture. The input data required is a computed tomography scan of the patient that is(More)
This paper presents the application of neural networks for the non-differential protection of salient-pole synchronous generator against internal faults in any winding of the stator. The direct phase quantities and modified winding function approach has been used to simulate different types of internal and external faults using electrical parameters of(More)
This paper presents the use of ANN as a pattern classifier for differential protection of power transformer, which makes the discrimination among normal, magnetizing inrush, over-excitation, external fault and internal fault currents. This scheme has been realized through two ANN architectures, which are designed and trained using feed forward back(More)
This paper proposes a new digital distance relaying algorithm for first-zone protection for series compensated double-circuit transmission lines. The new method uses data from one end of the protected double-circuit lines to calculate the fault distance. It is shown that the new method is independent of load current, remote in feed and source impedances. To(More)
Main purpose of every relay is to detect and classify the fault and isolate the faulty part as soon as possible. Protective distance relays, which make use of impedance measurements in order to determine the presence and identification of faults, are not accurate to that extent after installed series capacitance on the line. In this proposed scheme, Neural(More)
A low cost and reliable protection scheme has been designed for a three phase induction motor against unbalance voltages, under voltage, over voltage, short circuit and overheating protection. Taking the cost factor into consideration the design has been proposed using microcontroller Atmega32, MOSFETs, relays, small CTs and PTs. However the sensitivity of(More)
This paper presents the effect in the breaking capacity of previously installed circuit breaker due to the upcoming of new generating stations in the near vicinity. The MVA capacity of the circuit breaker needs to be upgraded owing to increase in the symmetrical fault current level. The circuit breaker connected to the older generating station can(More)
