Optimal Policy for Minimal Repair
Journal of the Operational Research Society, 1983The problem of replacement under minimal repair is considered. It is shown that a particular form of control limit policy is optimal in the space of all possible policies. This generalises a previous result.

A Bayesian Nonparametric Test for Minimal Repair
Technometrics, 2014The article develops a Bayesian nonparametric reliability model for recurrent events where failure and truncated time-to-failure density shape is regressed on past maintenance decisions: perfect repair and minimal repair. By comparing the system interfailure lifetime distributions after minimal and perfect repair, we are able to test the minimal repair

Optimal inspection models with minimal repair
Reliability Engineering & System Safety, 2020Abstract Although the logistics support is indispensable in maintaining defense systems, there may exist some situations that systems have to be operated in no logistics support and maintenances of systems are performed with constraint stocks. Although repairing by brand-new parts improve system reliability, repairing by degraded parts may not ...

Minimal repair in heterogeneous populations
Journal of Applied Probability, 2004The notion of minimal repair is generalized to the case when the lifetime distribution function is a continuous or a discrete mixture of distributions (heterogeneous population). The statistical (black box) minimal repair and the minimal repair based on information just before the failure of an object are considered.

Minimally invasive mitral valve repair
Heart, 2018### Learning objectives Modified cardiopulmonary bypass techniques, including vacuum-assisted venous drainage, were introduced in 1995 and enabled safe and effective minimally invasive mitral valve (MV) surgery. Approaches have evolved since the first successful right parasternal, trans-sternal and right mini-thoracotomy heart valve surgeries.1–3 ...

In this chapter, we consider systems that, once the failure has occurred and the repair has been completed, exhibit identical conditions to that just before the failure. In this case, minimal repair maintenance actions are being carried out in the system environment.

Minimal Spatio-Temporal Database Repairs
2015This 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

Tetralogy of Fallot Repair with Minimal or No Ventriculotomy
Journal of Cardiac Surgery, 1987Twenty-four consecutive patients with the tetralogy of Fallot underwent repair from March 25, 1985 to March 24, 1986. Correction was achieved without a ventriculotomy in 8 patients, necessitated a minimal ventriculotomy in 8, and a formal right ventriculotomy incision was required in the other 8. There were no early or late phase deaths-0% (70% C.L. 0%-

Minimally invasive mitral valve repair
Current Opinion in Anaesthesiology, 2014Meanwhile mitral valve insufficiency is probably the second most common heart valve disease represented in cardiac surgery. Due to low perioperative morbidity and mortality, nowadays mitral valve repair can even be considered in asymptomatic patients.

Minimal spatio-temporal database repairs
Proceedings of the 21st ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2013This work tackles the management of novel types of inconsistencies in Spatio-Temporal Databases, different from traditional database settings where integrity constraints pertain to the explicitly stored (or, defined via views and aggregates) values.
