This paper provides steady state queue-size distribution for a G/G/1 queue by using principle of maximum entropy. For this purpose we have used average queue length and normalizing condition as constraints to derive queue-size distribution. Our results give good approximation as demonstrated by taking a numerical illustration. In particular case when square coefficient of variation of inter-arr...

 In this paper, we discuss different estimators of the records Weibull distribution parameters and also we apply the Kullback-Leibler divergence of survival function method to estimate record Weibull parameters. Finally, these estimators have been compared using Monte Carlo simulation and suggested good estimators.

in this paper, the conjugate gradient method coupled with adjoint problem is used in order to solve the inverse heat conduction problem and estimation of the time- dependent heat flux using the temperature distribution at a point in a three layer system with none homogeneous boundary conditions. also, the effect of noisy data on final solution is studied. for solving this problem the general co...

High-dimensional data sets are often embedded in two-dimensional spaces so as to visualize neighborhood relationships. When the map is effective (i.e. when short distances are preserved) it is a powerful way to help an analyst to understand the data set. But, mappings most often show defaults and the user is then led astray. According to this notion, a mapping should not be considered when its ...

The finite-state based dialogue management approaches are powerful for simple tasks with strict and reliable dialogue control, while the plan-based dialogue management approaches are feasible for tasks with several topics or one complex topic. However, neither one is good enough for the dialogue control throughout in a dialogue task providing flight information inquiry and ticket reservation se...

The software architecture community has advocated design rationale in the last decade. However, there is little knowledge of how much reasoning is performed when software design judgments are made. In this study, we investigated the amount of design reasoning performed before making a decision. We recruited 32 students and 40 professionals to participate in this software architecture design stu...

Is being responsible good enough? Stone (1975) argued that we need corporate moral responsibility because neither law nor market is adequate to forestall harmful effects of business activities. However, it is not possible for businesses to become responsible for all forms of foreseeable, preventable harm that they produce. This is illustrated here by cases from insurance, television programming...

This article presents an experimental investigation of OPW treatment for oil removal by integration of two processes: coalescer bed and microfiltration membranes (MF). The main goal is to reach an effluent quality good enough for injection, discharge or reuse in surface activities. The objective of processes combination is to overcome operational problems and limitations that both processes pre...

In the commonly used DE/rand/1 variant of differential evolution the primary mechanism of generating new solutions is the perturbation of a randomly selected point by a difference vector. The newly selected point may, if good enough, then replace a solution from the current generation. As the replaced solution is not the one perturbed to create the new, candidate solution, when the population h...
