a r t i c l e i n f o For the 'under maintained' and 'over maintained' problems of traditional preventive maintenance, a new predictive maintenance policy is developed based on process data in this article to overcome these disadvantages. This predictive maintenance method utilizes results of probabilistic fault prediction, which reveals evolvement of the system's degradation for a gradually de...

The theories of reliability and diagnostics, despite their close relationship, have been mostly treated as two separate fields in the literature. However, it has been shown in the past few years that their dual character can be exploited in the context of modular systems. Such systems have a great practical impact on reliability computation and diagnostics, since their structure can be used to ...

A grand challenge impeding optimal treatment outcomes for patients with cancer arises from the complex nature of the disease: the cellular heterogeneity, the myriad of dysfunctional molecular and genetic networks as results of genetic (somatic) and environmental perturbations. Systems biology, with its holistic approach to understanding fundamental principles in biology, and the empowering tech...

This paper considers the problem of Power Plant Preventive Maintenance Scheduling (PPPMS). The goal is to evaluate which generators must stop production to be checked periodically for safety reasons. Preventive maintenance is crucial because a failure in a power plant may cause a general breakdown in an electric grid. This situation might result in a disruption of electric service to customers....

Conducting preventive maintenance of measurement sensors in real-time during process operation under feedback control while ensuring the reliability and improving the economic performance of a process is a central problem of the research area focusing on closed-loop preventive maintenance of sensors and actuators. To address this problem, a robust moving horizon estimation (RMHE) scheme and an ...

the present study was performed to analyze some of the preventive vs. promoter factors of applying blended learning system in agricultural higher education as viewed from the perspective of khuzestan province's faculties of agriculture and natural resources' faculty members. statistical population of the study consisted of the members of agriculture and natural resources state college...

The diagnostic system discussed in this paper provides an agent-based approach to advanced on-board diagnostics of operation and communication failures occurring in an electronic automotive system. To facilitate development and testing of agent-based automotive diagnostics, a software simulator of automotive electronics systems, also based on multi-agent technology, has been implemented, allowi...
