Monitoring and analysis of high frequency acoustic emissions on marine diesel engines may indicate their condition with the aim to increase engine availability and reduce maintenance overheads for the Defence Force. An experimental study was undertaken to evaluate the application of acoustic emission (AE) sensing to the monitoring of both petrol and diesel internal combustion engine operating c...

The overall dependability of an interactive system is the one of its weakest component which is usually its user interface. The presented approach integrates techniques from the dependable computing field and elements of user-centred design to provide a wider coverage of possible faults. Risk analysis and fault tolerance techniques are used in combination with task analysis and modelling to des...

Electrical energy is a vital source of for human life. Currently, various power plants can provide electrical energy, one which the Steam Power Plant (PLTU). A PLTU must carry out operational tasks repeatedly and continuously to meet electricity needs. Based on historical data PT. PJB Service Kendari last three years, there has been an increasing trend downtime derating at Nii Tanasa in 2019–20...

Analytical method validation ensures that a provides trustworthy information about particular sample when applied in accordance with the predefined protocol. According to regulatory standards, rheological characteristics of topically semisolid formulations are one key elements involved microstructure equivalence documentation. Therefore, for generic drug product manufacturers, it is dire need t...

Traceability information systems in food supply chains (FSCs) can suffer from loss, and this cause safety crises economic downturns around the world. Information loss happens as a result of inefficiencies material flows caused by vulnerabilities associated with either internal traceability individual FSC operators and/or external between them. A structured comprehensive approach to identify ana...

Reliability centered maintenance (RCM) is a new strategic framework for evaluating system requirements in its operating conditions. Some industries employ predictive strategies addition to preventive (PM) strategies, which increase production costs. As the breakdown (BDM) technique used, cost increases. The RCM approach mixture of these that can be used optimize costs and ensure availability sy...

The risk assessment of engineering systems represents an important part the quality service and dependability. existing methods for evaluation use crisp sets rating partial indicators’ proposition their cumulative products as overall indicator. In this paper, FMEA FMECA have been improved using fuzzy expert system calculating priority number. application logic allows linguistic descriptions ana...
