An Algorithm for the Selection of Physical System Model Order Based on Desired State Accuracy and Computational Efficiency
(American Society of Mechanical Engineers (ASME), 2003)
In recent years, algorithms have been developed to help automate the production of dynamic system models, The focus of this development has been to create procedures and algorithms that use modeling metrics for generating ...
Complexity of distributed parameter bond graph models
(The Society for Modeling and Simulation International, 2014)
Modeling metrics and algorithms that assist the development of dynamic system models are essential for efficient use of modeling and simulation in everyday engineering tasks. Various modeling procedures have been proposed ...
Model reduction of modal representations
(American Society of Mechanical Engineers (ASME), 2006)
Dynamic analysis is extensively used to study the behavior of continuous and lumped parameter linear systems. In addition to the physical space, analyses can also be performed in the modal space where useful frequency ...
A review of proper modeling techniques
(Affiliation: University of Michigan, Department of Mechanical Engineering, Ann Arbor, MI, United StatesAffiliation: University of Cyprus, Department of Mechanical and Manufacturing Engineering, Nicosia, CyprusAffiliation: Memorial University of Newfoundland, Department of Engineering and Applied Science, St. John's, NL, CanadaCorrespondence Address: Ersal, T.University of Michigan, Department of Mechanical Engineering, Ann Arbor, MI, United Statesemail: tersal@umich.edu, 2008)
A dynamic system model is proper for a particular application if it achieves the accuracy required by the application with minimal complexity. Because model complexity often - but not always - correlates inversely with ...
Implementation of IEEE single precision floating point addition and multiplication on FPGAs
(Affiliation: Rutgers Univ, Piscataway, United StatesCorrespondence Address: Louca, LoucasRutgers Univ, Piscataway, United States, 1996)
Floating point operations are hard to implement on FPGAs because of the complexity of their algorithms. On the other hand, many scientific problems require floating point arithmetic with high levels of accuracy in their ...
Determining model accuracy as a function of inputs and system parameters
(American Society of Mechanical Engineers (ASME), 2004)
Vital to the effectiveness of simulation-based design is having a system model of known quality. Previous research introduced an algorithm called AVASIM for assessing model validity systematically and quantitatively. AVASIM ...
A model accuracy and validation algorithm
(American Society of Mechanical Engineers (ASME), 2002)
Dynamic models of physical systems with physically meaningful states and parameters have become increasingly important, for design, control and even procurement decisions. The successful use of models in these contexts ...
Solution of viscoplastic flows with the finite volume / multigrid method
(National Technical University of Athens, 2013)
We investigate the performance of the finite volume method in solving viscoplastic flows. The square lid-driven cavity flow of a Bingham plastic is chosen as the test case and the constitutive equation is regularised as ...
