PS PLUS software offers power providers the ability to implement intelligent gas turbine life cycle management processes. Operators wish to achieve higher availability by reducing unnecessary scheduled outages for either inspection or repair. PS-PLUS is a SPAR-based application that uses the MonteCarlo (MC) method to estimate machinery remaining useful life. The method predicts the scope and sc...

The gearbox system is one of the most critical subassemblies in offshore wind turbine (OWT) drivetrains whose failures could lead to long downtimes and high repair costs. Therefore, it crucial accurately diagnose predict faults at an early stage development. This study develops a new dynamic Bayesian network (DBN) framework for fault diagnosis reliability analysis OWT systems by incorporating c...

BACKGROUND AND OBJECTIVES This study examines the effects of a single session of Cognitive Bias Modification to induce positive Interpretative bias (CBM-I) using standard or explicit instructions and an analogue of computer-administered CBT (c-CBT) program on modifying cognitive biases and social anxiety. METHODS A sample of 76 volunteers with social anxiety attended a research site. At both ...

Following successful outcomes of cognitive bias modification (CBM) programs for alcoholism in clinical and community samples, the present study investigated whether different varieties of CBM (attention control training and approach-bias re-training) could be delivered successfully in a fully automated web-based way and whether these interventions would help self-selected problem drinkers to re...

UNLABELLED Social anxiety is a common mental disorder among adolescents and is associated with detrimental long term outcomes. Therefore, this study investigated the efficacy of two possible early interventions for adolescent social anxiety and test anxiety. An internet-based cognitive bias modification (CBM; n = 86) was compared to a school-based cognitive behavioral group training (CBT; n = 8...

Today, poor long-term performance and durability combined with high production and maintenance costs remain the main obstacles for the commercialization of the polymer electrolyte membrane (PEM) fuel cells (PEMFCs). While on-line diagnosis and operating condition optimization play an important role in addressing the durability issue of the fuel cell, health-monitoring and prognosis (or PHM) tec...

The main goal of a Case-Based Reasoning (CBR) system is to provide criteria for evaluating the internal behavior and task efficiency of a particular system for a given initial case base and sequence of a solved problems. The choice of Case Base Maintenance (CBM) strategies is driven by the maintainer's performance goals for the system and by constraints on the system's design and the task envir...

We develop a matrix algebra approach for optimizing condition-based maintenance with planning time gradually deteriorating, continuously monitored equipment. This avoids the calculation times of simulation and approximations more direct approaches. consider model in which after failure should be planned as well, resulting downtime, emergency repairs upon failure. Numerical examples are provided...
