the need to establish power plants to supply the required electricity of the country has been rising due to increasing demand levels as well as the lack of governmental resources. furthermore, the available traditional attitude in performing and conducting power plant projects has made government seek a modern attitude. this paper tries to use the topics that have been employed in automotive in...

In the present investigation, we deal with the reliability characteristics of a repairable system consisting of two independent operating units, by incorporating the coverage factor. The probability of the successful detection, location and recovery from a failure is known as the coverage probability. The reboot delay and common cause shock failure are also considered. The times to failure of t...

The paper presents a multi-factor decision-making approach for prioritizing failure modes as an alternative to traditional approach of failure mode and effect analysis (FMEA). The approach is based on the ‘technique for order preference by similarity to ideal solution’ (TOPSIS). The priority ranking is formulated on the basis of six parameters (failure occurrence, non-detection, maintainability...

 Mobile sensor networks rely heavily on inter-sensor connectivity for collection of data. Nodes in these networks monitor different regions of an area of interest and collectively present a global overview of some monitored activities or phenomena. A failure of a sensor leads to loss of connectivity and may cause partitioning of the network into disjoint segments. A number of approaches have be...

Indian railway is one of the largest networks in country. Its motto “the life line country”, and main transport completed by railways Railroad cheapest safest means transport, but there are also certain accidents on railroad. 60% caused road failures or formation cracks road. Today’s rail systems involve manual track inspection, which cumbersome not entirely effective. However, detection correc...

scid disorder is major failure of the immune system, usually genetic. the aim of this study was on mutations detection of rag1, rag2, and il7rg genes in scid cases. mutation detection was performed by pcr sequencing. our results  indicated  that 13  mutations  were found  through  cases which  include 4 mutations in il7r gene (t661i, i138v, t56a, c57w), 7 mutations in rag1 (w896x, w204r, m324v,...
