Urban Commuting and Daytime Population In Small Areas of a Metropolis: A Case Study of Brno, Czech Republic
(University of Zagreb, Faculty of Transport and Traffic Sciences, 2009-06-18)
A simplified modelling approach to urban commuting patterns is achieved by focusing on daytime populations ratherthan on commuters, or on the commuting process itself.
Aggregation behavior of novel hyaluronan derivatives-a fluorescence probe study
Aggregation properties of hydrophobized hyaluronan (hHA) in different molecular weights and degree of substitution were studied by pyrene and perylene fluorescence method. The critical aggregation concentration (cac) was ...
Electronically adjustable mixed-mode implementations of the jerk functions
(Hikari Ltd., 2009-06-22)
In this paper the several structures of the third-order nonlinear oscillator with electronically adjustable parameters are presented. A brief numerical analysis including the computation of the largest Lyapunov exponent ...
Optimalizace výpočtového modelu místnosti s chladicím trámcem pomocí experimentálního měření v reálných podmínkách

Simulační řešení je v dnešní době jednou z nejaktuálnějších metod, pomocí které lze postihnout výměnu tepla, látky a dynamiku tekutin ve zkoumaném prostoru. Nejzásadnější předpoklad správného zpracovávání numerických CFD ...
Sunflower Plants as Bioindicators of Environmental Pollution with Lead (II) Ions
In this study, the influence of lead (II) ions on sunflower growth and biochemistry was investigated from various points of view. Sunflower plants were treated with 0, 10, 50, 100 and/or 500 mu M Pb-EDTA for eight days. ...
Crack propagation in the vicinity of the interface in layered materials
(University of West Bohemia, 2009-01-04)
Paper deals with the problem of crack propagation in the vicinity of the interface in layered materials. Layered materials are often used in practice, primarily because of their better mechanical properties in comparison ...
Fracture mechanics parameters of multilayer pipes
(University of West Bohemia, 2007-10-19)
Multilayer pipes consisting of different materials are frequently used in praxis because of partial improvement of the properties of pipe systems. To estimate lifetime of these pipes the basic fracture parameters have to ...
Glass fibre reinforced cement based composite: fatigue and fracture parameters
This paper introduces the basic fracture mechanics parameters of advanced building material - glass fibres reinforced cement based composite and its fracture and fatigue behaviour is investigated. To this aim three-point ...
Simulation of energy demands for the internal microclimate formation in BSim software and its verification
(IBPSA-CZ, ČVUT, 2008-11-06)
This article deals with the description and verifying energy model building in BSim software. Results of energy demands simulation for the internal microclimate formation in a real dwelling house carried out on the basis ...
Detailed balance in reaction kinetics - consequence of mass conservation?
Detailed balance condition for triangular isomerisation mechanism is derived from the more general permanence of atoms, consequently, it should be viewed as a special equilibrium result of mass conservation.
