Some results for repairable systems with minimal repairs

Applied Stochastic Models in Business and Industry, 2013
In this paper, we consider a repairable system with minimal repairs whose number of repairs is a positive random variable with a given probability vector. Some preservation theorems and aging properties of repairable systems are established. Under the condition that at time t the system is working, a new random variable for the residual lifetime of the

Minimally Invasive Repair of Pectus Excavatum

Seminars in Thoracic and Cardiovascular Surgery, 2009
The minimally invasive approach for repair of pectus excavatum has become widely accepted by pediatric and thoracic surgeons primarily because of increased patient awareness and good long-term outcomes. Although the technique is considered fairly new, it was quickly embraced by many, resulting in a significant increase in the number of such procedures ...

Optimal Preventive Replacement Under Minimal Repair and Random Repair Cost

Mathematics of Operations Research, 2000
A repair/replacement problem for a single unit system with random repair cost is considered. When the unit fails, the repair cost is observed and a decision is made whether to replace the unit or repair it. We assume that the repair is minimal, i.e., the unit is restored to its functioning condition just prior to failure, without changing its age. The

On some minimal repair model

Microelectronics Reliability, 1980
Abstract This paper deals with a one-unit system under the new maintenance policy subject to a minimal repair and a preventive maintenance. Under this policy, the Laplace transform of the point-wise availability and the stationary availability of the system are obtained using the supplementary variable method.

MACULAR HOLE REPAIR WITH MINIMAL VITRECTOMY

Retina, 2002
Conventional macular hole surgery usually involves removing 80% of the intraocular contents to repair a hole a few hundred micrometers in diameter. Although the success rate for conventional surgery is good, it may be possible to reduce the number of complications with less invasive surgery.A newly designed microspatula knife was used to dissect the ...

Minimally Invasive Ptosis Repair

2008
Minimally invasive ptosis surgery offers many advantages—a less visible scar, a reduced surgical time, and an improved postoperative period—and it is as effective and reliable as the traditional surgical approach. I have been delighted with the minimally invasive approach in aponeurogenic ptosis.

Minimally Invasive Pauli Parastomal Hernia Repair

Surgical Laparoscopy, Endoscopy & Percutaneous Techniques
Background: Although originally described as an open procedure, the application in the setting of minimally invasive surgery of the Pauli technique for parastomal hernia repair is gaining interest among surgeons owing to encouraging early results.

A general minimal repair model

Journal of Applied Probability, 2000
Minimal repairs have been given considerable attention in the reliability literature. Instead of replacing a failed system by a new one, such a minimal repair restores the system to the state it had just before failure. But the state just before failure depends on the information which is available about the system.

Minimal Spatio-Temporal Database Repairs

2015
This work addresses the problem of efficient detection and fixing of inconsistencies in spatio-temporal databases. In contrast to traditional database settings, where integrity constraints pertain to explicitly stored values and values defined via views and aggregates, spatio-temporal data may exhibit other types of constraint violations that cannot be
