ACM Transactions on Modeling and Computer Simulation (TOMACS), Volume 18 Issue 4, September 2008

Guest editors' introduction to special issue on successes in modeling and simulation methodologies
Simon J. E. Taylor, George Riley
Article No.: 13
DOI: 10.1145/1391978.1391979

3D reconstruction and visualization of astrophysical wind volumes using physical models
Ioannis Pachoulakis
Article No.: 14
DOI: 10.1145/1391978.1391980

This article reports on the application of a framework used to model, simulate and visualize the 3D structure of astrophysical wind volumes. The modeling methodology is similar to multidirectional medical tomography in that the spatial structure...

Stochastic formulation of SPICE-type electronic circuit simulation with polynomial chaos
Kai Strunz, Qianli Su
Article No.: 15
DOI: 10.1145/1391978.1391981

A methodology for efficient tolerance analysis of electronic circuits based on nonsampling stochastic simulation of transients is formulated, implemented, and validated. We model the stochastic behavior of all quantities that are subject to...

Approximate bivariate gamma generator with prespecified correlation and different marginal shapes
Simon Rosenfeld
Article No.: 16
DOI: 10.1145/1391978.1391982

A new algorithm is proposed for generating approximate bivariate gamma random samples with a prespecified correlation coefficient and different marginal shapes. A distinctive feature of this approach is computational simplicity and ease of...

A framework for the simulation of structural software evolution
Benjamin Stopford, Steve Counsell
Article No.: 17
DOI: 10.1145/1391978.1391983

As functionality is added to an aging piece of software, its original design and structure will tend to erode. This can lead to high coupling, low cohesion and other undesirable effects associated with spaghetti architectures. The underlying...
