To develop a mechanistic bacterial dose–response model, based on the concept of Key Events Dose–Response Framework (KEDRF), this study aimed to investigate the invasion of intestinal model cells (Caco‐2) by Salmonella Typhimurium and Listeria monocytogenes and described the behaviour of both pathogens as a mathematical model using Bayesian inference. Monolayer‐cultured Caco‐2 cells (approximately...
This paper examines the asymptotic behavior of a newly defined general form of partial directed coherence. Both confidence interval and null hypothesis testing results are presented and illustrated.
Motivated by performance evaluation of a computer communication system, we consider a renewal input, general service time, single-server, and infinite-capacity queuing system with generally distributed time-out threshold. We obtain two moment approximate formulas for the mean system performance measures (including the mean number of customers in the system and the mean response time) by using the...
We consider a single-server GI/G/1 queueing system with modified service mechanism. By modified service mechanism, we mean that the service time distribution (H0) for the customers arriving to find the system idle may be different from the service time distribution (H1) for the customers arriving to find the system busy. We present qualitative relationships among the performance measures in the system...
A comparison of incorporation schemes of dissipation in the FDTD analysis of transmission lines using stability analysis is described. In the leapfrog type FDTD method, the calculation points of the voltage and the current are different in the time space. Therefore, how dissipation is included in the update equation becomes a problem. We find that incorporation of dissipation by using average value...
A 1D finite-difference time-domain (FDTD) method for nonuniform transmission line analysis by using wavelet expansion is presented. The approach are based on scaling functions only or on a combination of scaling functions and wavelets leading to a variable mesh griding. The proposed schemes compared to the conventional Yee's FDTD scheme shows a good capability to approximate the exact solution with...
This paper describes the consideration of an optimum ecology driving technique to be used for electric vehicles. Modern control theory is considered to obtain the optimal running pattern. A simple mathematical model of the electrical vehicle was derived based on ideal conditions in which outside disturbances are not considered. The optimal running pattern was revealed in results from a simulation...
In this paper, the performance of peer-to-peer (P2P) file sharing service based-on flooding search algorithm is analyzed. We focus on six types of four-terminal four-router physical network, and investigate the impact of topology inconsistency and flooding search on the file retrieval performance. The analysis model is based on a two-layer queueing network in which both logical and physical topologies...
An improved model of sealed Ni-Cd button cells has been developed to answer diversified requirements needed when used as a backup power source to retain the semi-conductor memory in micro-computers. Its features include: (1) Improved salting-proof performance. (2) Long life at elevated temperature. (3) Lower self-discharge rate. The cells are believed to be highly reliable for use as a backup power...
