In a system subject to both repairable and catastrophic (i.e., nonrepairable) failures, ‘mission success’ can be defined as operating for a specified time without a catastrophic failure. We examine the effect of a burn-in process of duration t on the mission time x, and also on the probability of mission success, by introducing several functions and surfaces on the ðt; xÞ-plane whose extrema re...
For a manipulator operating in a hazardous or remote environment, an important concern is its capability after a component failure, since retrieval or repair is not always possible. Methods have been presented in the literature for optimizing capabilities after specific types of failures. However, techniques for achieving failure tolerance when conversion between failure types is possible has n...
An ontology for representing operating, safety and control procedures is proposed in this paper that supports diagnosis based on following these procedures and combining observed malfunctions with Failure Mode and Effects Analysis (FMEA) information. The procedure ontology is defined within interconnected components of the process plant, diagnostic analysis (where the FMEA is described) and pro...
When designing aerospace systems, it is essential to provide crucial failure information for failure prevention. Failure Modes and Effects types of analyses and prior engineering knowledge and experience are commonly used to to determine the potential modes of failures a product might encounter during its lifetime. When new products are being considered and designed, this knowledge and informat...
Modern embedded systems contain complex structures, as they are composed of many subsystems. Maintaining such systems requires collaboration between the engineers who designed them and the engineers who analyzed the failures in them. In this paper we present our proposed visual platform ESSAVis, a 2Dplus3D environment, to help both kinds of engineers in understanding the failure mechanisms of s...
background exertional heat stroke (ehs) is still a main cause of death in sport. many of ehs complications could have been prevented if ehs had been recognized and treated early and properly. case presentation we report an unusual case of multiple organ failure caused by ehs due to intensive sportive activities in a hot environment with lack of primary care. a 35-year-old healthy sportive man w...
Shock is one of the most frequently diagnosed, yet poorly understood disorders in the pediatric intensive care unit (PICU). The very definition of what constellation of physical signs and symptoms that comprise shock remains controversial, in part due to the vast array of disorders that cause shock in critically ill and injured children. Early management and reversal of the shock state is assoc...
BACKGROUND Patients with heart failure who receive an implantable cardioverter-defibrillator (ICD) for primary prevention (i.e., prevention of a first life-threatening arrhythmic event) may later receive therapeutic shocks from the ICD. Information about long-term prognosis after ICD therapy in such patients is limited. METHODS Of 829 patients with heart failure who were randomly assigned to ...
adequately ventilate), or both hypoxic and hypercapnic. In addition, respiratory failure can be caused by an inability to protect the airway. Alterations in the normal physiology and anatomy of the respiratory system can lead to respiratory failure requiring mechanical ventilation. Anatomic alterations causing airway obstruction, such as tumors, edema, direct or indirect trauma, burns, or other...
