Rotating equipment is widely used in large industrial and mining enterprises, so its safe stable operation of great significance. With rapid development artificial intelligence algorithms recent years, many researchers apply them to the fault diagnosis rotating machinery equipment. This paper takes a company’s as an object, discusses suitable for remote diagnosis. Then, taking circulating water...

For the heavy ion programme of the LHC a new ECRIS type heavy ion source had to be designed and built for Linac3 to fullfill the intensity requirements. Experience acquired during the installation and commissioning of the source and during operation for the LEIR ring commissioning will be presented. The performance of the source and its reliability are evaluated. Further requirements for high r...

An innovative space-conditioning system is proposed and a life-cycle assessment (LCA) is presented. The layout is obtained starting from a ground-source heat pump system (GSHP) and includes upstream thermal storage (TS). A prototype of the system, implemented following this new approach, is currently in use for space heating and cooling of an industrial building. As a result of the TS designed ...

Background: Sexual dysfunction is one of the most common problems in men after coronary artery bypass graft (CABG). Etiology of sexual dysfunction in these patients may be psychological or organic due to hormonal changes. The purpose of this study was to evaluate the incidence and type of sexual dysfunction and changes in serum concentration of sex hormones in male patients undergoing on-pump C...

preventive maintenance scheduling of generating units is addressed as a long-term scheduling in power system studies aiming to increase the reliability incorporating cost reduction. it consists of knowing which generating units should be shut down for regular safety inspection. in this paper, a new formulation of preventive maintenance scheduling associated with cost reduction index (cri) is pr...

The use of pumps linked in parallel or series in large scale pipe systems is usually inevitable, to meet the required head and discharge. Transient flow occurs following a pump failure in a pump group as a result of variations in the flow rate. This research is an investigation about waterhammer caused by one or more pump-switch off in a pump group when they are connected in parallel. The opera...
