Implications of equipment failure occurring during surgery [PDF]
The Annals of The Royal College of Surgeons of England, 2022 Introduction Few formal studies have been performed investigating the frequency of equipment failure during surgery. Surgeons are unable to operate without the plethora of instruments and equipment surrounding them in the operating theatre. As with any mechanical component, instruments and equipment are subject to time- and use-dependent degradation in

Diagnosis of Equipment Failures
IRE Transactions on Reliability and Quality Control, 1960This paper introduces several new concepts which are applicable to the problem of diagnosis of equipment failures. Following the definitions of an equipment, an element of the equipment, and the model of a test, a general diagram of a testing procedure is developed.

On Predicting the Times to Failure of Power Equipment
2010 43rd Hawaii International Conference on System Sciences, 2010Across power systems, large classes of identical devices can be found which support the system operation (transformers, breakers, switches, utility poles, etc.) The problem of their operational management is often aggravated by in-service failures and associated additional costs. Part of asset management strategy is to learn the failure characteristics

Failures Monitoring in Refrigeration Equipment
2018The refrigerators are the responsible to assure the temperature and humidity conditions for perishable products stored in it. In this sense, it is necessary to guarantee its good performance at all times in order to preserve the products. In this article We propose a failures monitoring system for refrigeration equipment using Internet of Things (IoT ...

Failures Identification in Refrigeration Equipment
2020 IX International Congress of Mechatronics Engineering and Automation (CIIMA), 2020A refrigerator is an essential element in the preservation of perishable products; if there is some damage, its poorly performance prevents to guarantee the quality of the products contained in it, because the temperature and humidity conditions of the container are not the desired.

Prediction of Power Equipment Failures Based on Chronological Failure Records
2006 IEEE International Symposium on Circuits and Systems, 2006When power utility asset managers are facing the task of resource planning for future deployment, often times, only partial information is available: installation dates and amounts, as well as failure and replacement rates. By combining records on yearly populations of the components, estimation of failure model parameters may be possible.

Journal of the Operations Research Society of America, 1953
This paper had its origin in consideration of the work reported on by D. M. Boodman [Boodman, D. M. 1953. The reliability of airborne radar equipment. Jour. Op. Res. Soc. America 1 (February) 39–45.]. The purpose is to examine some of the implications arising from the assumption that a piece of complex equipment fails when, and only when, one of its ...

The Failure Law of Complex Equipment
Journal of the Society for Industrial and Applied Mathematics, 1960below which is slightly more general than Palm’s, and a somewhat different approach is adopted. The viewpoint is more particularly taken here that the problem is in the nature of a probabilistic limit theorem, and that accordingly the addition of independent variables and the central limit theorem is a useful prototype.
