Mathematical moddeling of radiobiological mechanism in cells
Lokajíček st., Miloš ; Kundrát, Pavel
A mathematical model will be presented thet enables to correlate the inactivation effect of defined numbers of ionizing particles traversing cell nuclei with corresponding cell survival curves. Applications of the given model in analyzing the relative biological efficiency of protons and ions in their Bragg peak regions will be discussed
Air pollution model development for complex terrain and it´s application to KRNAP
Jaňour, Zbyněk ; Bílek, V. ; Holpuch, J. ; Kozel, K.
A sopfisticated eulerian dispersion model consisting on numerical solution of flow and diffusion equations on limit area is introduced. The model is applied to the Giant Mountains.
Study of mechanics as a search for interrelations
Höschl, Cyril
Author presents examples of analogous problems from various fields of mechanics of elastic solids which are solved using an identical mathematical model. Paper deals also with discrepancies between solutions obteined either by analytical or numerical methods. By the use of functional analysis, an interrelation is found between methods of solution of discrete and continuum models. The limitations of the linear theory of elsticity are discussed.
Flood situations influence on water quality in reservoirs controlled by means of mathematical modelling
Kafková, Dagmar ; Balejová, Marcela
Příspěvek se zabývá možnostmi matematického modelování pro sledování vývoje kvality vody v nádržích za běžných provozních podmínek i během extrémních povodňových situací se zvláštním zreželem na nádrž Pastviny na Divoké Orlici. Pro tuto nádrž byl upraven dvourozměrný matematický model CE-QUAL-W2, který se již dříve osvědčil při modelování nádrže Římov na Malši. Validaci modelu pro nádrž Pastviny nelze v současné době považovat za dokončenou, protože z předchozích let není k dispozici dostatečné množství bilogických a chemických dat, avšak bathymetrická data již odpovídají současnému stavu po vypuštění a vyčištění nádrže a model je připraven pro použití, jakmile budou potřebná data shromážděna.
Fieldless Methods for the Simulation of Induction Heating of 3D Non-Ferromagnetic Metal Bodies
Doležel, Ivo ; Šolín, Pavel ; Ulrych, B.
In the present study we introduce a class of novel methods for the mathematical modelling and numerical solution of the induction heating of non-ferromagnetic metal bodies in harmonic electromagnetic fields. The main advantage of the presented approach is the elimination of the surrounding air from the electromagnetic model.
Mathematical modelling of processes in surroundings of underground radioactive waste repository
Blaheta, Radim ; Kohut, Roman ; Šňupárek, Richard
The solution of stability and safety of underground repositories of the spent nuclear fuel requires to use mathematical modelling of coupled thermal, hydrogeological and mechanical processes in rock mass. The contribution deals with methods of mathematical modelling and describes some examples of model problems, which are relevant for the assessment of geological repositories and can be used for testing of numerical methods and the corresponding software.
Numerical Analysis. Proceedings of the seminar dedicated to the jubilee of Ivo Marek
Blaheta, Radim ; Starý, Jiří
This proceedings contains the extended abstracts of the contributions delivered at the Seminar on Numerical Analysis, held at the Institute of Geonics AS CR Ostrava. The scope of the seminar includes study of algorithms for the solution of problems of continuous mathematics, algorithms of numerical linear algebra and application of the numerical methods in mathematical modelling.
