The contribution rate of equipment system-of-systems architecture (ESoSA) is an important index to evaluate the update, development, and optimization. Since traditional ESoSA evaluation method does not make full use fuzzy information uncertain in (ESoS), Bayesian network effective tool solve information, a new based on (FBN) proposed. Firstly, operation loop theory, constructed considering thre...

During the ageing of in-service medium voltage equipment, electrical losses are mainly due to partial discharges. These partial discharges can lead to the electrical failure of industrial equipment [1]. Partial discharges include (i) bulk discharges occurring in insulating material voids, (ii) corona discharges affecting or not the insulator and (iii) surface discharges developing on an insulat...

Wireless devices and systems have been deployed in many communication sectors but have not yet been adequately adapted to harsh industrial environments. Cost effective, reliable and scalable wireless technologies have yet to be introduced in industrial plants, including petroleum plants. At this time, there are very few, if any, cost-effective Commercial-Off-The-Shelf (COTS) radios available th...

BACKGROUND Staphylococcus aureus is a leading cause of healthcare-associated infections (HAIs), but the impact of S. aureus HAIs on the long-term survival and functional status of hospitalized patients remain unknown. This study aimed to examine whether S. aureus HAIs increase the risks for long-term mortality and disability. METHODS We conducted a retrospective population-based matched cohor...

A small ventilation failure alarm which can be used with all types of lung ventilator is described. The entire patient circuit can be removed and autoclaved easily. Activation of the unit is by a removable key, a mains failure warning is provided, and alarm may be muted during aspiration of secretions from the tracheobronchial tree.

Thick-walled high-pressure vessels are a fairly common type of technical device as part technological equipment operated at various hazardous production facilities. Reliability indicators pressure and their change during operation largely determine the failure-free whole, potential failures subject to consideration when conducting risk analysis operating equipment. The article discusses probabi...

Article history: Received 26 June 2015 Received in revised form 23 November 2015 Accepted 30 November 2015 Available online 7 December 2015 In areas with hot weather, photovoltaic systems can be used to help relieve the peak demand caused by air conditioning equipment. Users, however, are reluctant to invest in solar technology, arguing that the equipment commercially available is unreliable be...

This article deals with the assessment of the reliability of sensitive equipment due to voltage sags. The most frequent problems of power quality are voltage sags. Equipment that cannot withstand short-term voltage sag is defined as sensitive device. Sensitivity of such equipment can be described by the voltage–tolerance curves. A device (generator) to generate voltage sags (also interruptions)...
