Please cite this article in press as: Kumar S doi:10.1016/j.microrel.2009.09.016 This paper presents an approach for selecting precursor parameters for health monitoring of electronic products. The approach includes failure modes, mechanisms, and effects analysis (FMMEA) and life cycle profile analysis of a product. The criticality of the failure mechanisms is established using a risk priority ...

Progressive collapse is defined as the spread of an initial failure from element to element, eventually resulting in the collapse of an entire structure or a disproportionately large part of it. The current progressive collapse analyses and design methods in guidelines and codes focus on the alternate load path method. This method is suitable especially in the case of blast-induced progressive ...

We introduce in this paper a new four-parameter generalized version of the linear failure rate distribution which is called Beta-linear failure rate distribution. The new distribution is quite flexible and can be used effectively in modeling survival data and reliability problems. It can have a constant, decreasing, increasing and bathtub-shaped failure rate function depending on its parameter...

Safety and failure in gas pipelines are very important in gas and petroleum industry. For this reason, it is important to study the effect of different parameters in order to reach the maximum safety in design and application. In this paper, a three dimensional finite element analysis is carried out to study the effect of crack length, crack depth, crack position, internal pressure and pipe thi...

BACKGROUND Acute gastrointestinal bleeding (GIB) is a life-threatening abdominal emergency and can be treated by transarterial embolization (TAE). Rehemorrhage and poor outcome are associated with several clinical factors. This study investigated the clinical and angiographic parameters associated with treatment failure for patients with acute GIB undergoing TAE. METHODS Sixty-seven patients ...

In this paper we introduce a four-parameter generalized Weibull distribution. This new distribution has a more general form of failure rate function. It is more general for modeling than six ageing classes of life distributions with appropriate choices of parameter values, so it can display decreasing, increasing, bathtub shaped, unimodal, increasing-decreasing increasing and decreasing-increas...
