| In this paper, M/G/C/C state dependent queueing models are proposed for modeling and analyzing vehicular traac ows. Congestion aspects of traac ow are represented by introducing state dependent service rates as a function of number of vehicles on each road link. Analytical models for unidirectional and multi-source ows are presented. Finally, queueing models to analytically determine the opti...

The machine repair problem with spares and additional repairman is analyzed. The interfailure and repair times of the units are general identical and independently distributed. The failure and repair rates are assumed to be state dependent. Using diffusion approximation technique, we obtain the queue size distribution under steady state. The average number of failed units, average number of ope...

power electronic converters are non-linear time-dependent systems whose exact analysis without the use of computers is very difficult, and even using computer softwares requires a long time. use of the state space averaging method, as will be mentioned, in addition to simplifying the analysis procedure which is a result of converting a time-dependent system to a time-independent one, reduces th...

This paper is pertained with the problem of admissibility analysis of uncertain discrete-time nonlinear singular systems by adopting the state-space Takagi-Sugeno fuzzy model with time-delays and norm-bounded parameter uncertainties. Lyapunov Krasovskii functionals are constructed to obtain delay-dependent stability condition in terms of linear matrix inequalities, which is dependent on the low...

premenstrual syndrome (pms) is a hormone dependent pathophysiologic state with known somatic and affective symptoms. vitamin d3 as a secosteroid hormone has different effects on several disorders. in this review, we declared some potential benefits of vitamin d3 regarding alleviation of pms symptoms; also, we have reported the results of literature review about vitamin d and pms.

An analytical equation of state was applied to calculate the thermodynamic properties for argon.The equation of state is that of Song and Mason. It is based on a statistical-mechanical perturbationtheory of the hard convex bodies and can be written as fifth-order polynomial in the density. Thereexist three temperature-dependent parameters: the second virial coefficient, an effective molecularvo...
