Widespread acceptance of micro-electro-mechanical systems (MEMS) depends highly on their reliability, both for large-volume commercialization and for critical applications. The problem of multiple dependent failure processes is of particular interest to MEMS researchers. For MEMS devices subjected to both wear degradation and random shocks that are dependent and competing, we propose a new reli...

i n troduction: users’ behavioral intention to use the picture archiving and communication system (pacs) is important in the systems’ success and is an indicator of the users’ satisfaction with commitment and dependence on information systems. the present study aimed to evaluate the users’ continuous intention to use pacs based on the expectation confirmation model in educational hospitals of s...

Electrical Mechanical Systems for Command, Control, Communications. Essentially the area under the curve defined by the PDF of the PDF from t.The reduction of system reliability due to accumulated damage is quantitatively. THE reliability of a mechanical system may be defined as the.The estimation of reliability of mechanical systems under variable constraints. The probability density function ...

Functionality for efficient computation of properties of system lifetimes was developed, based on the Mathematica framework. The model of these systems consists of a system structure and the component’s independent lifetime distributions. The components are assumed to be non-repairable. In this work a very general implementation was created, allowing a large number of lifetime distributions fro...

Distributed systems often employ replication to solve two different kinds of availability problems. First, to prevent the loss of data through the permanent destruction or disconnection of a distributed node, and second, to allow prompt retrieval of data when some distributed nodes respond slowly. For simplicity, many systems further handle crash-restart failures and timeouts by treating them a...

A general model for describing, evaluation and control of most common reliability characteristics of multi-stage systems with gradual failures and repairs of the whole system is proposed. The steady state probabilities and the Laplace transform of the reliability function are calculated.

Reliability is a key parameter for the eventual prevalence of microelectromechanical systems (MEMS) as either sub-components or as standalone products. Traditionally, micromachined components have been made by separating the micromachined chip design and fabrication processes from the packaging and reliability issues. This “evolutionary” partitioning of microsystems has led to long incubation t...
