We propose a model for disorderly streetcar routes. Through simulations and comparisons to real data, we illustrate that such routes may sometimes become supersaturated, in the sense that forward and backward waiting times become positively correlated.
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
this study is an outlook of iranians religious practices and customs in eras such as nasser one. it attempts to answer the main question, "religious practices and ceremonies in the society during naseri ruling" and other subsidiary questions with scientific and historical theories. iran was a traditional and religious community . people abided by their religious practices and duties within reli...
there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...
background in early 2012, national health insurance scheme (nhis) members in ashanti region were allowed to choose their own primary healthcare providers. this paper investigates the factors that enrolees in the ashanti region considered in choosing preferred primary healthcare providers (ppps) and direction of association of such factors with the choice of ppp. methods using a cross-sectiona...
Introduction: This article proposes a method which could improve the performance of an Emergency Department (ED) in a large hospital in Tehran, where the long waiting times cause patients’ and ED staff ’s dissatisfaction. ED is considered as a bottleneck in hospitals. To reduce long waiting time and improve patient satisfaction, application of system improvement methods is required....
the waiting time between children births are called tempo. this phenomenon plays a crucial role in the child and mother health. the purpose of the present study is determination of factors which influence this variable of interest. a significance level of 5% and power of 80% considered to calculate the required sample size for this cross sectional study. the sample size of 124 women determined ...
Using a weak migration and weak mutation approximation, I studied the average waiting time to parapatric speciation. The description of reproductive isolation used is based on the classical Dobzhansky model and its recently proposed multilocus generalizations. The dynamics of parapatric speciation are modelled as a biased random walk performed by the average genetic distance between the residen...
In this paper we study a single-server queue with FIFO service and cyclic interarrival and service times. An efficient approximative algorithm is developed for the first two moments of the waiting time. Numerical results are included to demonstrate that the algorithm yields accurate results. For the special case of exponential interarrival times we present a simple exact analysis.
