Traffic simulation represents an effective tool for evaluating the suggested alternatives to enhance traffic conditions prior to their application in real sites. U-turn sections represent examples of the complicated sections that cannot be analyzed properly without applying microsimulation approach.  Recently, in Iraq, speed humps were applied in prior to the merging locations and U-turn sectio...

OBJECTIVES The aim of this study was to explore the influence of the characteristics of Japanese patients on the long-term outcomes after aortic valve replacement with either mechanical or biological prostheses by means of a microsimulation. METHODS A microsimulation model was used to simulate the lives of patients living in Japan and in the United States after aortic valve replacement. The b...

A dynamic microsimulation model of cohort earnings based on the Australian population aged between 20 and 55 years is described. A highly parsimonious modular structure is adopted to facilitate sensitivity analysis and enable additional characteristics to be added, should they be desired. Despite the restrictive specifications used, the model closely reflects the data used for calibration. JEL ...

S imulation models, now widely used in the physical sciences, can also help economists in depicting the actions and interactions of individuals and firms through time. Such models can be built and run on any personal computer. They can illuminate a wide variety of issues that are difficult to analyze with an economist's conventional tool-kit and are especially useful in studying dynamic process...

Interval-censored longitudinal data taken from a Norwegian study of individuals with Parkinson's disease are investigated with respect to the onset of dementia. Of interest are risk factors for dementia and the subdivision of total life expectancy (LE) into LE with and without dementia. To estimate LEs using extrapolation, a parametric continuous-time 3-state illness-death Markov model is prese...

in this paper, we show that the chapman-kolmogorov formula could be used as a recursive formula for computing the m-step-ahead conditional density of a markov bilinear model. the stationary marginal probability density function of the model may be approximated by the m-step-ahead conditional density for sufficiently large m.

This paper demonstrates a model{chain that is able to determine environmental impacts of traac. The dynamic microsimulation models described cover the problems of traac assignment and calculation of emissions by microscopic vehicle states. Due to their computational eeciency the model{chain promises to be applicable even for large networks with millions of drivers. First results will be presented.

The paper examines the application of semi-Markov models to the phenomenon of earthquakes in Tehran province. Generally, earthquakes are not independent of each other, and time and place of earthquakes are related to previous earthquakes; moreover, the time between earthquakes affects the pattern of their occurrence; thus, this occurrence can be likened to semi-Markov models. ...
