This paper deals with a reliability model developed for a single-unit system which may fail completely either directly from normal mode or via partial failure. There is a single server who inspects the unit at its partial and complete failure to examine the feasibility of repair. If repair of the unit at these stages is not feasible, it is replaced immediately by new one. The system remains ope...

this study examines inventory management practices of flour milling manufacturing firms and their effects on operational performance. five flour milling manufacturing firms in lagos were used for this study. structured questionnaire was the major instrument for the collection of relevant primary data while descriptive statistics such as mean and standard deviation was deployed to analyzing the ...

feed resources availability at cheap and affordable prices for livestock consumption are major factors determining capability of livestock production to supply products for increasing urban and cities consumers in nigeria. to take advantages of the high demand in urban areas, livestock producers on extensive pastoralism are moving closer to cities and urban communities such as abuja the nigeria...

in this study a heat exchanger is designed for cooling exhaust gas and an experiment is carried out to investigate the effect of exhaust gas recirculation (egr) temperature on destruction of the fuel’s availability due to combustion processes in idi diesel engine cylinder. to serve this aim an exergy analysis is conducted on the engine cylinder which provides all the availability terms by which...

dianchi lake is one of the most three seriously eutrophic lakes in china. in the present study, the phosphorus (p) and nitrogen (n) fractions in 37 surface sediments samples collected in the dianchi lake were investigated. the total phophorus (tp) in sediments was divided into two parts: inorganic p (ip) and residual p (res-p). the results showed that the total phosphorus content in surface sed...

Because the inductive noise Ldi/dt is induced by the power change and can have disastrous impact on the timing and reliability of the system, high-performance CPU designs are more concerned with the step power reduction instead of the average power reduction. The step power is defined as the power difference between the previous and present clock cycles, and represents the Ldi/dt noise at the m...

Abstract - One of the important problems in grid environments is data replication in grid sites. Reliability and availability of data replication in some cases is considered low. To separate sites with high reliability and high availability of sites with low availability and low reliability, clustering can be used. In this study, the data grid dynamically evaluate and predict the condition of t...
