Today, in a competitive market, service organizations and producers have a great attention to optimization and customer satisfaction in order to become competitive. Service organization must reduce the number of arrival, waiting time and service time in the queue to increase the customer satisfaction. In this paper by the aim of queuing theory we analyze the optimal amount of increment in a rep...

Two hundred and forty four patients underwent either simultaneous bilateral inguinal hernia repair (n = 122) or unilateral inguinal hernia (n = 122) repair at a general hospital between January 1971 and December 1981. The two groups of patients were matched for age and sex. Both groups had a similar overall incidence of post-operative complications and in both groups the duration of post-operat...

Background: Inguinal hernia repair in men is one of the most common operations in general surgery. Techniques of surgical repair include open suture, open mesh and laparoscopic techniques. Successful hernia surgery is a series of minimums, specifically minimum risk of surgery and anesthesia, minimum tissue trauma, confinement, complications, cost, disability and recurrence. The most effective s...

SOME APPLICATIONS OF RELIABILITY ANALYSES OF STANDBY REDUNDANT SYSTEMS WITH REPAIR Michikazu Kumagai , Toshiba Research & DeveZopment Center 169 Some applications are discussed concerning reliability analyses of a standby redundant system with repair. The system consists of a series subsystem composed of N identical units and n spares. Failed units are assumed to be repaired by r repair facilit...

We investigate the complexity of computing an optimal repair of an inconsistent database, in the case where integrity constraints are Functional Dependencies (FDs). We focus on two types of repairs: an optimal subset repair (optimal S-repair) that is obtained by a minimum number of tuple deletions, and an optimal update repair (optimal U-repair) that is obtained by a minimum number of value (ce...

introduction : although many techniques have been described for reconstruction of the giant omphalocele, we present a simple , effective and safe new technique. materials and methods: we have studied 11 neonates with giant omphalocele that were treated by a new technique, umbrella repair, in sarvar pediatric hospital of mashhad, iran. in this new technique we released the skin around the omphal...

We recently developed a high-resolution genome-wide assay for mapping DNA excision repair named eXcision Repair-sequencing (XR-seq) and have now used XR-seq to determine which regions of the genome are subject to repair very soon after UV exposure and which regions are repaired later. Over a time course, we measured repair of the UV-induced damage of cyclobutane pyrimidine dimers (CPDs) (at 1, ...
