a full scale physical model of a thin slab caster with a four-hole design submerged entry nozzle (sen) was constructed. on the basis of the dimensionless reynolds and froude similitude criteria, the fluid flow in a full-scale model is similar to that of the actual system and, hence, the data obtained from the water model can be applied to the actual system. in order to determine the optimum ope...

The reason why the term physical modeling has been coined is the need to distinguish between two extreme approaches to physical systems modeling. On the one extreme we have so called ’black-box modeling’ where a mathematical model is fitted to measurements. On the other extreme we have physical modeling in which case we only use insight into the system structure combined with known physical law...

Bimrocks are complex geomaterials that are defined as mixtures of rocks composed of geotechnically significant blocks within a matrix of finer texture. Bimslopes are made from bimrocks and are usually seen in weathered and shallow environments. Some characteristics of blocks affecting the strength of bimrocks include VBP (Volumetric Block Proportion), orientation, and arrangement, which have im...

Platform based design uses high speed embedded processors, FPGAs, and ASICs as targets for implementation of a system model. Application of this design approach to physical response modeling is described and results are given. The approach shows promise for providing a PC based simulation acceleration environment. A new modeling approach using a cascading cellular automata methodology is discus...

Modeling physical systems seems to be a straightforward task. Since physical systems and experiments are often reproducible in a reliable fashion, since measurements from physical systems are frequently available in abundance and of high quality, since the meta{laws of physics are mostly well understood, it seems to be a particularly easy task to come up with accurate mathematical descriptions ...

Automating analysis of physical systems requires techniques for managing complexity and finding an appropriate model for an analysis . Compositional modeling is a strategy for organizing multi-grain, multi-perspective models of physical phenomena which addresses these problems . In this paper, we identify several limitations with the approach presented in [7] and describe important extensions t...

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau...

By semi-physical modeling we mean such an application of system identiication, where physical insight into the application is used to come up with suitable nonlinear transformations of the raw measurements, so as to allow for a good model structure. Semi-physical modeling is less "ambitious" than physical modeling, in that no complete physical structure is sought, just suitable inputs and outpu...
