We present a framework, called SWiMNet, for parallel simulation of wireless and mobile PCS networks, which allows realistic and detailed modeling of mobility, call traffic, and PCS network deployment. SWiMNet is based upon event precomputation and a combination of optimistic and conservative synchronization mechanisms. Event precomputation is the result of model independence within the global P...

Two analytical procedures for identifying young children as categorizers, the Monte Carlo Simulation and the Probability Estimate Model, were compared. Using a sequential touching method, children aged 12, 18, 24, and 30 months were given seven object sets representing different levels of categorical classification. From their touching performance, the probability that children were categorizin...

Fine timescale simulation and analysis are combined with coarse timescale simulation in the design and performance evaluation of connection admission control (CAC) techniques applied to connections that utilize the asynchronous transfer mode (ATM) Adaptation Layer Type 2 (AAL2). Fine timescale (packet-level) simulation and then analytical modeling are used to determine the AAL2-level connection...

In this paper, a new model for resonance frequency of clamped circular corrugated diaphragm has been presented. First, an analytical analyzes has been carried out to derive mathematic expressions for mechanical sensitivity of diaphragm with residual stress. Next by using Rayleigh's method we present mathematical model to calculate the resonance frequency of corrugated diaphragm and investigate ...

one of the most important structural components of engine compartment assembly in a car body is the srail. s-rails has significant role in absorbing energy during crash events and therefore it is designed for efficient behavior in such conditions. driving the peak crushing force of the s-rails is one of the important objectives in the design process of such structures. peak crushing force is ex...

the performance of water flooding can be investigated by using either detail numerical modeling or simulation, or simply through the analytical buckley-leverett (bl) model. the buckley-leverett analytical technique can be applied to one-dimensional homogeneous systems. in this paper, the impact of heterogeneity on water flooding performance and fractional flow curve is investigated. first, a ba...

We present the findings of an extensive case study for the decomposed, simulation-based, optimal design of an advanced technology heavy truck by means of analytical target cascading. The use of a series hybrid-electric propulsion system, in-hub motors, and variable height suspensions is considered with the intention of improving both commercial and military design attributes according to a dual...

Abstract. This paper analyzes compressible gaseous slip flow through a three-dimensional straight uniform rectangular microchannel, and reports a set of asymptotic solutions. By comparing the magnitudes of different forces in the compressible gas flow, we obtain a proper criteria to estimate the Reynolds and Mach numbers at the channel exit. We select two sets of Mach and Reynolds numbers and o...

Before the wide deployment of underwater sensor networks becomes a reality, one of the challenges that needs to be resolved is efficient error recovery in the presence of high error rates, node mobility and long propagation delays. In this paper, we propose an efficient error-recovery scheme that carefully couples network coding and multipath routing. Through an analytical study, we provide gui...

This paper considers a performance prediction for various computer networks in terms of the number of references made to the memory. Analytical solutions were obtained for the models with multiple requests to the memory and parallel access to one memory bank with a Negative Exponential distribution of requests generated by CPUs. Numerical simulation was carried out for Hypercube, Cube Connected...
