We consider the Erlang A model, or [Formula: see text] queue, with Poisson arrivals, exponential service times, and m parallel servers, and the property that waiting customers abandon the queue after an exponential time. The queue length process is in this case a birth-death process, for which we obtain explicit expressions for the Laplace transforms of the time-dependent distribution and the f...

Introduction: Enriched Environment (EE), a complex novel environment, has been demonstrated to improve synaptic plasticity in both injured and intact animals. The present study investigated the capacity of an early environmental intervention to normalize the impairment of passive avoidance memory and Long-Term Potentiation (LTP) induced by transient bilateral common carotid artery occlusion (2-...

Background: Classical signal processing methods for neuronal oscillations, such as EEG and LFP, usually rely on the strong restrictive assumptions of stationarity and ergodicity. However, electrical potentials from the brain are well known for displaying statistical properties that vary over time giving rise to transient patterns [1]. Moreover, decomposition methods in the literature not only u...

A mathematical model of solute transient diffusion across the cornea to the anterior chamber of the eye was developed for topical drug delivery. Solute bioavailability was predicted given solute molecular radius and octanol-to-water distribution coefficient (Phi), ocular membrane ultrastructural parameters, tear fluid hydrodynamics, as well as solute distribution volume (Vd) and clearance rate ...

Reply to previous reviews (of the published NPGD paper): We once again thank both reviewers for their comments, which we tried our best to reflect in the revised manuscript (all changes with respect to the previous version are highlighted). Reviewer 2 remains to be concerned with the alleged lack of novelty in our approach and results. While we have indeed been unaware of the previous work on t...

The transient behavior of an ecosystem with N random interacting species in the presence of a multiplicative noise is analyzed. The multiplicative noise mimics the interaction with the environment. We investigate different asymptotic dynamical regimes and the role of the external noise on the probability distribution of the local field. Population dynamics attracted a lot of attention in recent...

In the present investigation transient, G x/G/m queuing model with balking and reneging has been studied. The diffusion process with elementary return boundary has been used for modeling purpose. The probability density function (p. d. f.) for the number of customers in the system has been obtained. In special case, the steady state results that tally with those of Kimura and Ohsone have been e...

Lattice gas automata (LGA) model is developed to simulate polymer adsorption process by adding some collision rules. The simulation result of the model is matched with batch experiment and compared with accepted isothermal adsorption equations. They show that the model is viable to perform simulation of the polymer adsorption process. The LGA model is then applied for simulating continuous poly...

Software is often constructed using a layered approach to encapsulate various functionality in corresponding layers. Individual requirements of each layer demand layer specific data structures. These data structures typically provide redundant information with respect to the data source. Providing a Model Driven Software Development approach for creating these data structures leads to overlappi...
