Article history: Received 28 October 2011 Accepted December, 5 2011 Available online 8 December 2011 Continuous generation of electricity of a power plant depends on the higher availability of its components/equipments. Higher availability of the components/equipments is inherently associated with their higher reliability and maintainability. This paper investigates the reliability, availabilit...

the present paper deals with development of a simulation model for the performance evaluation of feed water system of a thermal power plant using markov birth-death process and probabilistic approach. in present paper, the feed water system consists of four subsystems. after drawing transition diagram for feed water system, differential equations are developed and then solved recursively using ...

Multi-component machining systems are being used in every sphere of engineering sector such as job shops, flow lines, communication system, computer system, etc. This paper presents fuzzy analysis of availability characteristics of machining system comprising of multiactive units and multi-standby units. The Markov machine repair model has been developed by incorporating the concepts of switchi...

The systolic array paradigm has low communication demand because it does not use costly global communication and each processor communicates with few other processors. It is thus suitable to be used in cluster computing. The systolic approach, however, is vulnerable in a heterogeneous environment where machines perform differently. In this paper we propose a redundant systolic solution with hig...

The aim of this investigation was to assess the bioavailability and pharmacokinetics of oxytocin in six male subjects after a sublingual dose of 400 int. units (684 micrograms) and after an intravenous dose of 1 int. unit (1.71 micrograms). After intravenous administration, the pharmacokinetic profile could be described with a two-compartment model. The distribution half-life was 0.049 +/- 0.10...

Three experiments involving 162 pigs were conducted to assess the efficacy of phytase (Natuphos; BASF, Mount Olive, NJ) in low-P, corn-soybean meal-based diets. The phytase was produced by a recombinant Aspergillus niger. The phytase supplement contained 5,000 phytase units (PTU)/g. In Exp. 1 (66 pigs) and 2 (60 pigs), growing-finishing pigs were fed fortified corn-soybean meal diets formulated...

Project scheduling problems are in practice often restricted by a limited availability of spatial resources. In this paper we develop a decomposition method for the Time-Constrained Project Scheduling Problem (TCPSP) with Spatial Resources. Spatial resources are resources that are not required by single activities, but by activity groups. As soon as an activity of such a group starts, the spati...
