The paper allocates a stochastic model on threesimilar units three-phased mission system. developed system consists of working in parallel, series and parallel configurations respectively. Initially, the three similar are operational. Each component has only states: good, degraded failed. In this case, single repair facility that repairs first come serve (FCFS)pattern been thought of. Using Sem...

Fifteen to 20 years ago, transversalis and Shouldice Hospital repairs were standard, with a 4% to 6% rate of recurrence. With a focus on recurrence, various mesh repairs were proposed to reduce the incidence of recurrence. With these repairs, an increased incidence of inguinodynia due to the entrapment of the nerves proximate (adjacent) to the mesh has been observed. Many surgeons doubted its e...

This paper is concerned with the dependence structure of a multi-component, cumulative damage shock model, in which a system of components is subject to correlated shock damages and group repairs. A component fails when its cumulative damage exceeds a given threshold, and is then replaced by a new component. We incorporate a block maintenance schedule that simultaneously performs imperfect repa...

BACKGROUND The success rate of rotator cuff repairs is variable. This study was performed to evaluate the ability of recombinant human bone morphogenetic protein-12 (rhBMP-12), administered in several carriers, to accelerate healing in a sheep model of rotator cuff repair. METHODS Local retention of tracer amounts of radiolabeled rhBMP-12, added to non-radiolabeled rhBMP-12 delivered in buffe...

PURPOSE To compare the outcome of open versus endoscopic gluteal tendon repair. METHODS An extensive review of PubMed was conducted by 2 independent reviewers for articles containing at least 1 of the following search terms: gluteus medius, gluteus medius tear, gluteus medius tendinopathy, gluteus medius repair, hip abductors, hip abductor tears, hip abductor repair, hip rotator cuff, hip rot...

Active integrity constraints (AICs) are a form of integrity constraints for databases that not only identify inconsistencies, but also suggest how these can be overcome. The semantics for AICs defines different types of repairs, but deciding whether an inconsistent database can be repaired is a NPor Σ p-complete problem, depending on the type of repairs one has in mind. In this paper, we introd...

Answer set programming is a form of declarative programming that can be used to elegantly model various systems. When the available knowledge about these systems is imperfect, however, the resulting programs can be inconsistent. In such cases, it is of interest to find plausible repairs, i.e. plausible modifications to the original program that ensure the existence of at least one answer set. A...

PURPOSE The purpose of this study was to determine the impact of an endovascular stent-graft program on vascular training in open aortic aneurysm surgery. METHODS The institutional and vascular surgery fellow experience in aortic aneurysm repair during a 6-year period was reviewed. The 3-year period before introduction of endovascular repair was compared with the 3-year period after introduct...

INTRODUCTION Ventral hernia repairs are common surgical procedures and quality monitoring with a high validity is mandatory. The aim of the present study was to validate the data quality of the Danish Ventral Hernia Database (DVHD). MATERIAL AND METHODS All ventral hernia repairs performed in the Region of Zealand and registered in the DVHD between 1 October 2010 and 1 October 2011 were inclu...
