Using the ring of complex quaternions, the more active view of weakly coupled gauge fields is formulated in such a way that, in the SU(.2) x U(1) model of Salam, Ward, and Weinberg, for example, AS # 0, AQ 2 0 effects are properly suppressed without the appearance of a new quark field in the Lagrangian-only p, n, and h. quark fields appear. Here, S is strangeness and Q is electric charge. The s...

Most of the real life multi server queuing systems have heterogeneous servers which means each service rates are different than each other. Analysis of such queuing system plays important role to improve performance. In this report, I have summarized analysis of heterogeneous multi server queuing system which has a finite and an infinite buffer. Average waiting time and average queue length are...

BACKGROUND Changes in patient length of stay (the duration of 1 clinic visit) as a result of the introduction of an electronic patient file system forced an anesthesia department to change its outpatient clinic organization. In this study, we sought to demonstrate how the involvement of essential employees combined with mathematical techniques to support the decision-making process resulted in ...

With a large percentage of total system cost going to system administration tasks, ease of system management remains a difficult and important goal. As a step towards that goal, this dissertation presents a success story on building systems that are self-predicting. Self-predicting systems continuously monitor themselves and provide quantitative answers to What...if questions about hypothetical...

In our previous work, a highly scalable and faulttolerant network architecture, the Progressive Multi-hop Rotational Clustered (PMRC) structure, is proposed for constructing large-scale wireless sensor networks. Further, the overlapped scheme is proposed to solve the bottleneck problem in PMRC-based sensor networks. As buffer space is often scarce in sensor nodes, in this paper, we focus on stu...

Queuing theory has extensively studied the problem of estimating job execution times in steady state conditions both in the case of single queues and queuing networks. This paper discusses the use of closed Queuing Network (QN) models during finite time intervals to estimate the execution time of jobs submitted to a computer system. More specifically, the paper presents the Epochs algorithm tha...

Ribosome queuing is a fundamental phenomenon suggested to be related to topics such as genome evolution, synthetic biology, gene expression regulation, intracellular biophysics, and more. However, this phenomenon hasn't been quantified yet at a genomic level. Nevertheless, methodologies for studying translation (e.g. ribosome footprints) are usually calibrated to capture only single ribosome pr...

Modeling and predicting age differences in driver mental workload and performance may help the invehicle system design to reduce or prevent information overloading on older drivers. However, few computational models exist that account for age differences in mental workload. We propose a new computational modeling approach to model workload and performance—a queuing network approach based on que...

We show how agent-based simulation is used for analyzing different queuing strategies in the youth health care sector. The simulation model represents an authentic business case and is parameterized with actual market data. We discuss the differences between four queuing strategies which are based on push/pull allocation and centralized/decentralized queuing strategies. The model incorporates, ...

We present an analytical framework for providing Quality of Service (QoS) using queuing policies that achieves a given target distribution of packets in a network queue. Queuing policies are employed in an attempt to control the sending and receiving rates subject to the uncertainties in the environments. To a large extent, the stationary distribution of packets in the queue resulted from emplo...
