A method for robotized cable winding of the Uppsala University Wave Energy Converter generator stator has previously been presented and validated. The purpose of this study is to present and validate further developments to the method: automated stand-alone equipment for the preparation of the winding cables. The cable preparation consists of three parts: feeding the cable from a drum, forming ...

In this article, we use a genetic algorithm to obtain an economically optimal preventive maintenance frequency for different equipment, the parts inventory policy (number and type of spare parts to keep in stock), and labor allocation in process plants. To assess cost, we improved a previously published Monte Carlo simulationbased maintenance model (Nguyen et al. Ind. Eng. Chem. Res. 2008, 47(6...

ite power and grounding audits/evaluations of commercial and industrial locations routinely identify electrical power system grounding and bonding problems. According to S. Frank Waterer, an electrical engineering IEEE Fellow at Schneider Electric with more than 30 years of experience, approximately 70% of all anomalies, dysfunctions, or problems associated with power distribution systems are d...

One enduring principle of rational inference is category inclusion: Categories inherit the properties of their superordinates. In five experiments, I show that people do not consistently apply this principle when evaluating categorical arguments involving natural categories and a single nonexplainable predicate such as all electronic equipment has parts made of germanium, therefore all stereos ...

Mechanical parts such as gears and bearings used in mechanical equipment have a finite lifetime because of corrosion and wear. If the parts are in abnormal operation and is not detected, it may cause catastrophic component failure during operation. One effective approach to detect signs of potential failure of the mechanical equipment is to examine the debris particles in its lubricating oil. T...

The cost of 3D printing has reduced dramatically over the last few years and is now within reach of many scientific laboratories. This work presents an example of how 3D printing can be applied to the development of custom laboratory equipment that is specifically adapted for use with the novel brain tissue clearing technique, CLARITY. A simple, freely available online software tool was used, a...

High-precision machine tools are important equipment of production line in general [1]. However, there has been more difficult on failure prediction and maintenance of its spindle bearings. There are no timely replacement of the bearing when the failure occurs will result in decreased equipment utilization. This paper designed a set of bearing failure prediction system based on LabVIEW programm...
