This paper studies the uid approximation, also known as the functional strong law-of-large-numbers, for a GI/G/1 queue under a processor-sharing service discipline. The uid (approximation) limit in general depends on the service time distribution, and the convergence is in general in the Skorohod J 1 topology. This is in contrast to the known result for the GI/G/1 queue under a FIFO service dis...

Constant entropy rate (conditional entropies must remain constant as the sequence length increases) and uniform information density (conditional probabilities must remain constant as the sequence length increases) are two information theoretic principles that are argued to underlie a wide range of linguistic phenomena. Here we revise the predictions of these principles to the light of Hilberg’s...

User interface (UI) is point of interaction between user and computer software. The success and failure of a software application depends on User Interface Design (UID). Possibility of using a software, easily using and learning are issues influenced by UID. The UI is significant in designing of educational software (e-Learning). Principles and concepts of learning should be considered in addit...

Contrary to the traditional view, seismic attenuation in Biot's theory of uid-saturated porous media is due to viscous damping of local (not global) pore-uid motion. Since substantial inhomogeneities in uid permeability of porous geological materials are to be expected, the regions of highest local permeability contribute most to the wave energy dissipation while those of lowest permeability do...

This study aims to analyze the factor affecting urban industry development in Guangzhou. Based on push-pull-mooring theory, we explain reasons for choosing above indicators and use order parameters their impact industrial development. The results show that: (1) Environment has an obvious promoting effect shows that current environment have reached a balance. (2) Technology positive development,...

The purpose of cosmological simulations is to model the growth of structure in the universe. The techniques described here model the mass density of the universe with a distribution of softened particles. Evolution is simulated by following the trajectories of these particles under their mutual gravity. Since the region of the universe modelled is typically very much smaller than the horizon vo...

in the current study, the immersed boundary – non-newtonian lattice boltzmann method is developed for simulation of forces act on a particle and also for computation of the particle velocity in vicinity of non-newtonian fluids. in this research, the effect of extra force due to accelerated mass is also considered in non-newtonian particle motion equations. two applied problems of power-law non-...

We study the free boundary between a viscous uid and an invis-cid uid satisfying the Navier-Stokes and Euler equations respectively. Surface tension is incorporated. To simplify the equations we read them as a free boundary problem for one viscous uid with a nonlocal boundary force. A decomposition of the pressure distribution in the inviscid uid identiies the main part of the generator. It is ...

This paper introduces the framework of synchronous constrained uid systems (SCFS) to model queueing networks driven synchronously by general uid virtual departure processes, and explores structural properties of queueing networks that t this model. The synchronous timing mechanism used in this paper allows us to model sources and servers with time-varying capacity as in communication systems wi...
