Background and Objectives: Careers related to body products are targeted toward saving patients from certain death. Such careers serve a necessary and important role. In case of the incidence of any human fault and organizational failure within the irreparable course of body product manufacturing, the negligent person is liable to pay compensation according to the principle of Tasbeeb (causatio...

In this paper, the seismic collapse probability of special steel moment-resisting frame (SSMRF) structures under near fault pulse-like and far fault ordinary ground motions is evaluated through fragility analysis. For this purpose, five sample frames with 3 to 15 stories are designed and imposed to the ground motion excitations with different characteristics. Fragility curves are derived for th...

Nowadays it is common to use the fragility curves in probabilistic methods to determine the collapse probability resulting from an earthquake. The uncertainties exist in intensity and frequency content of the earthquake records are considered as the most effective parameters in developing the fragility curves. The pulse-type records reported in the near-fault regions might lead to the major dam...

Detection of fault segments is an essential step for tracking main transverse faults. General observations from field studies as well as attitude measurements can give an overall understanding of the lengths of the segments, but these are not always sufficient to accurately identify and characterize them. In this study, we analyze P–T dihedra variations based on their eigenvalues to detect faul...

Fault diagnosis is an important task for the normal operation and maintenance of equipment. In many real situations, the diagnosis data cannot provide deterministic values and are usually imprecise or uncertain. Thus, interval-valued fuzzy sets (IVFSs) are very suitable for expressing imprecise or uncertain fault information in real problems. However, existing literature scarcely deals with fau...

Abstract— An important aspect of network management is fault management, i.e., determining, locating, isolating, and correcting faults in the network. We study modeling of communication network protocols, and their fault detection, fault identification and fault location in the discrete event systems diagnosis framework. Our approach provides a systematic way of performing fault diagnosis in ne...

The process of simple fault injection into Pspice simulation environment has the disadvantage of low efficiency and low degree of automation. To address this problem, a multi-fault injector is designed and implemented. It can not only be capable of the single fault injection, but also have the function of the batch injection for the same fault type. Firstly, this paper explains the fault inject...

one of the major problems that may occur in the differential protection systems of power transformers is mal-operation of the protection relays in sake of internal fault detection, because of similarity between this current and inrush current. this paper presents a novel approach for discriminating inrush current from internal fault in power transformers based on improved gravitational search a...
