Background and Aim : Emergency ward is among hospital areas with high risk of errors, thus, implementing measures to identify and correct the errors is essential. The object of this study is to identify and assess the errors of the process of admitting patients in Emergency Department of Imam Reza Hospital using Failure Mode Effects Analysis, as one of the tools to assess and manage risk, as we...

Failure Mode and Effects Analysis is widely used in engineering hardware systems to help in understanding the effects of potential failures and the faults that cause them to occur. The analysis is iterative leading to improvements in the design until the risks associated with potential failure modes are reduced to an acceptable level. Interest in applying the technique to software has increased...

In this paper we present a general framework for conducting robustness analysis early in the development life cycle of web-based systems. This framework exploits the robustness failure modes and evaluates the impact of modifications that can be applied to reduce the severity of these failures. First, the system is systematically decomposed in its components using Jacobson’s analysis. Next, with...

Ensuring fast and accurate failure detection is a fundamental issue for building efficient fault-tolerant distributed systems. In an effort to make fault-tolerant applications easier to implement, we are trying to provide failure detection as a generic Internet service, similar to what was done very successfully with NTP (network time protocol) for clock synchronization. To do so, we must revis...

Malay Niraj, Praveen Kumar, Dr. A.Mishra Abstract -Present study is an approach for f inding the suitable maintenance practice and frequency of maintenance with the help of criticality factor of equipment it is based on failure mode evaluation and criticality analysis. Criticality means the failure probability of the equipment is very high. The miner failure of critical equipment may leads to s...

This study numerically predicts the failure scenario of a cracked concrete gravity dam through a push-over nonlinear analysis. The mixed-mode Linear Elastic Fracture Mechanics (LEFM) was employed using the extended finite element method (XFEM). The dam base was considered to be fully fixed without any foundation effects. The hydrostatic pressure on the dam's upstream face was increased incremen...

A welding robot is an advanced piece of machinery in industry, especially in the field of industrial automation. As a complex system, it has a high failure probability because it manipulates, controls and performs complicated objects and tasks. Therefore, more attention has recently focused on the reliability of a welding robot. Reliability is very important because its performance will affect ...

The Failure Mode and Effects Analysis (FMEA) design discipline involves the examination at design time of the consequences of potential component failures on the functionality of a system. It is clear that this type of information could also prove useful for diagnostic purposes. Unfortunately, this information cannot be fully utilised for diagnosis when FMEA has been performed by human engineer...

Fully autonomous vehicles promise enormous gains in safety, efficiency, and economy. Before such gains can be realized, safety and reliability concerns must be addressed. We have previously introduced a system for managing such vehicles at intersections that is capable of handling more vehicles and causing fewer delays than traffic lights and stop signs [2]. While the system is safe under norma...
