Planetary gearboxes are widely used in manufacturing processes, and non-destructive assessment is becoming increasingly important for monitoring their state. We outlined a fine-tuned random decision tree (FT-RDT) this study classifying fault-finding the gearbox via signals generated by vibrations. This approach concentrates on identification of worn gears, consequently distinct classes—healthy ...

Many maintenance approaches have been developed and applied successfully in a variety of sectors such as aviation and nuclear industries over the years. Some of those have also been employed in the maritime industry such as condition based maintenance; however choosing the best maintenance approach has always been a big challenge due to the involvement of many attributes and alternatives which ...

OBJECTIVE Using clustering techniques for characterising companies providing health institutions with maintenance services. METHODS The study analysed seven pilot areas' equipment inventory (264 medical devices). Clustering techniques were applied using 26 variables. Response time (RT), operation duration (OD), availability and turnaround time (TAT) were amongst the most significant ones. R...

We address efficiency issues during the process of integrity maintenance. In this sense, we propose a technique that improves efficiency of existing methods by defining the order in which maintenance of integrity constraints should be performed. Moreover, we integrate view updating into integrity maintenance and we propose a technique for translating view updates efficiently, aimed at reducing ...

Materialised views are important in data warehouses where they are used to speed up query processing in decision support activities. There are many applications, such as those involving financial or stock market data for example, where the base data is volatile and the updates to the materialised views need to be computed efficiently. In such cases, incremental update techniques are often used ...

OBJECTIVES The aim of this article is to present the rationale, study design, and methods of an ongoing randomized controlled trial assessing the efficacy of an energy psychology intervention, Tapas Acupressure Technique (TAT), to prevent weight regain following successful weight loss. DESIGN This is a randomized controlled trial. SETTINGS/LOCATION The study is being conducted at a large gr...
