In the present investigation, we deal with the reliability characteristics of a repairable system consisting of two independent operating units, by incorporating the coverage factor. The probability of the successful detection, location and recovery from a failure is known as the coverage probability. The reboot delay and common cause shock failure are also considered. The times to failure of t...

This paper reports test results on electrical characteristics, evaluation of design, failure modes and reliability of thermally actuated, commercially available micromachined relays. The selected parts have been characterized over a wide range of temperatures (from – 100 °C to +180 °C) and varying load conditions (voltages from 10 V to 70 V, and currents from 5 mA to 200 mA). Mechanical integri...

Shock is a pathological condition characterized by imbalance between oxygen demand and supply. Irrespective of the cause, shock leads to state energy failure due decrease in adenosine triphosphate (ATP) production, creation lactic acidosis, as consequence, multiple organ dysfunction [1].

 In industry or nature, ‎there are systems subjected to a secuence of shocks ocurring randomly in time‎. ‎these shocks are causing aging or failure of system‎. ‎According to the type of shocks‎, ‎shock models divided in two major groups‎, ‎Extreme Shock Models and Cumulative Shock Models‎. ‎In the extreme shock models just impact of last shock named fatal shock would be studied and in the cumul...

Some complex systems experience multiple dependent competing failure processes, and many traditional approaches to reliability are inadequate or inappropriate because there are two or more dependent/correlated failure processes and multiple components subject to failure. A typical design example representative of these systems is Micro-ElectroMechanical Systems. The dependency among the failure...

Background: Myocardial infarction is the most important cause of mortality all over the world. Complications may increase with some risk factors including stress hyperglycemia. The aim of this study was to evaluate the correlation and importance of hyperglycemia in acute intrahospital complications after AMI. Methods: Prevalence of stress hyperglycemia among 160 patients with acute myocardial...

In very rare cases severe metabolic acidosis may cause hypotension, respiratory depression and cardiac arrest. Although rare this cause of shock is important because correction of the metabolic acidosis may be life-saving. Mild metabolic acidosis is relatively common in cases of hypoxia and shock, and is an index of the severity of these. Recurrent metabolic acidosis, which reflects failure of ...

In the United States, when medical devices are associated with adverse events that result in death or serious injury, or have malfunctions that could lead to death/serious injury, these events must be reported to the Food and Drug Administration’s Center for Devices and Radiologic Health by device manufacturers and user facilities. However, the defects in the medical device evaluation process (...

The rupture of rubber differs from conventional fracture. It is supersonic, and the speed is determined by strain levels ahead of the tip rather than total strain energy as for ordinary cracks. Dissipation plays a very important role in allowing the propagation of ruptures, and the back edges of ruptures must toughen as they contract, or the rupture is unstable. This article presents several le...
