Inspired by the successful application of q-Weibull distribution in other research fields, we took lead to use it field medical devices this work. The parameter estimation was performed using probability plot method. CT failure data from Nanfang Hospital Guangzhou, China, were used study reliability equipment at two levels: system and its seven main components. In terms evaluation accuracy, mea...

Quality and safety are intensely related go hand in hand. of the safety-grade equipment is very important for a nuclear power plant (NPP) achieving production goals. During manufacturing components or equipment, deviation from design might occur at different stages various reasons, such as lack skilled manpower, materials, human errors, malfunction violation procedure, etc. These deviations can...

In avionics application it’s fundamental that each system, sub-system or a component achieves a high level of reliability. To this aim, reliability prediction and an accurate test planning are required in the design phase in order to avoid undesirable fault or failure during the operating life cycle of any aeronautics equipment. In this paper, a research activity concerning the design and relia...

Abstract Over the last decade, several hyper-scale data center companies such as Google, Facebook, and Microsoft have demonstrated cost-saving capabilities of airside economization with direct/indirect heat exchangers by moving to chiller-less air-cooled centers. Under pressure from owners, information technology equipment OEMs like Dell IBM are developing that can withstand peak excursion temp...

background: the reliability and safety of gas refineries are strongly associated with the reliability of other parts of the system. defect and failure in one part of a system can cause total system breakdown or accident. the failure and damage in these equipment such as transformers and boilers results in not only the equipment damage and human injuries but also productivity reduction. the purp...

The relevance of reliability evaluation strongly depends on the quality of input data as failure rates. Reliability data handbooks give generic values which do not often fit system specificities. This paper deals with influencing factors in order to take into account some aspects as design, environment and use in reliability evaluations. Once a definition and a classification are proposed, a br...

For modern VLSI/ULSI fabrication the use of multilevel interconnects is of crucial importance. For electromigration reliability characterizations, time-consuming stress measurements have to be carried out [1,2]. During these measurements a via-hole chain is stressed because of high temperature and high current densities, and the resistance is determined. This type of measurement usually takes m...

The Automatic Identification System (AIS) is essential digital communication equipment for maritime safety in inland rivers. The occasional error of GNSS (Global Navigation Satellite System) devices in the AIS equipment will make the terminal send fake dynamic information discontinuously, which needs to be distinguished manually. With the help of the DSmT method, gathering and qualifying the sh...
