Alternaria sp. MG1, an endophytic fungus previously isolated from Merlot grape, produces resveratrol from glucose, showing similar metabolic flux to the phenylpropanoid biosynthesis pathway, currently found solely in plants. In order to identify the resveratrol biosynthesis pathway in this strain at the gene level, de novo transcriptome sequencing was conducted using Illumina paired-end sequenc...

This paper represents linkage network of queues consisting of biserial and parallel servers linked to a common server in series with a flowshop scheduling system consisting of two machines. The significant transportation time of the jobs from one machine to another is also considered. Further, the completion time of jobs/customers (waiting time + service time) in the queue network is the set...

This paper deals with the study of multi-server queueing model in a fuzzy environment imposition reneging customers. Entry customers system is assumed to be Poisson process and exponential service time distribution under first-come-first-served basis. Specific this investigation derive various performance measures such as queue length, waiting queue, response optimal number servers explicit for...

conclusions: the patients' waiting times and the number of patients waiting to receive services in both shifts could be reduced by using multitasking persons and reallocating them to the time-consuming stage of filling prescriptions, using queuing theory and simulation techniques. background: hospital pharmacy is responsible for controlling and monitoring the medication use process and ensures ...

Time dependent availability is an important index used for evaluation of operational performance of repairable industrial systems. Traditionally, Markov analysis procedures are carried out for such studies. This becomes mathematically intensive when applied for larger systems. Moreover, this method does not indicate at what time a system reaches its steady state. However, in practice it is impo...

— The inter-die and intra-die variation in process parameters (in particular, threshold voltage (Vt)) result in large number of failures in an SRAM array degrading the design yield. The adaptive repairing techniques, such as adaptive body bias, can be used to improve the design yield. However, to apply adaptive repairing techniques it is necessary to distinguish between the dies from low-Vt pro...

The popular models for repairable item inventory, both in the literature as well as practical applications, assume that the demands for items are independent of the number of working systems. However this assumption can introduce a serious underestimation of availability when the number of working systems is small, the failure rate is high or the repair time is long. In this paper, we study a m...

Kijima and Sumita have proposed a stochastic model called the generalized renewal process (GRP) to describe the availability characteristics of repairable systems by introducing the notion of the virtual age of the system. Yanez et al. offer maximum likelihood estimation (MLE) approach for estimating parameters of the GRP models. Due to the complexity of the equations, a close solution is not a...
