Combined replacement models
نویسنده
چکیده
— This paper summarizes ten replacement models which combine tkree basic replacements: (i)age replacement; (ii)block replacement; (in) periodic replacement with minimal repair at failure. The expected cast rates ofeach model are derived, using the usual caktdus method ofprobabitity. As an example, we give an optimum policy to minimize the expected cost rate ofone model

Prediction of operative mortality after valve replacement surgery.
OBJECTIVES We sought to develop national benchmarks for valve replacement surgery by developing statistical risk models of operative mortality. BACKGROUND National risk models for coronary artery bypass graft surgery (CABG) have gained widespread acceptance, but there are no similar models for valve replacement surgery. METHODS The Society of Thoracic Surgeons National Cardiac Surgery Datab...
متن کاملA One-Stage Two-Machine Replacement Strategy Based on the Bayesian Inference Method
In this research, we consider an application of the Bayesian Inferences in machine replacement problem. The application is concerned with the time to replace two machines producing a specific product; each machine doing a special operation on the product when there are manufacturing defects because of failures. A common practice for this kind of problem is to fit a single distribution to the co...

متن کاملCombining X-ray and electron-microscopy data to solve crystal structures
Low-resolution electron-microscopy reconstructions can be used as search models in molecular replacement or may be combined with existing monomeric structures in order to produce multimeric models suitable for molecular replacement. The technique is described in the case of viral and subviral particles as well as in the case of oligomeric proteins.
متن کاملBRUCELLA MELLITENSIS ENDOCARDITIS: DIAGNOSIS AND TREATMENT IN SIX ADULT PATIENTS.
Brucella endocarditis is an uncommon but not rare manifestation of brucellosis in our country. We report six adult patients aged 20 to 45 years. Two of our patients were female, and this is the first time that Brucella endocarditis was reported in adult females. In five cases, aortic valve replacement was performed in addition to combined antibiotic therapy. One of them died due to immedia...
