River revitalization for fish
Szarowski, Marcin ; Novotný, Jaroslav (referee) ; Milerski, Rudolf (advisor)
The case study provided for this bachelor’s thesis is based on the issue of rehabilitation of rivers for fish. The first part contains the recherché and the second part conceptual design. Substance of the revitalization is restoration of rivers to natural form. The thesis describes typical landscaping measures suitable for complex treatment of rivers in Czech Republic. Main benefit of revitalization is aquatic improvements in our rivers. The second section of this work includes examples of problem solution on the river Svratka.
Diagnostic analyzes of an existing family house
Novotný, Jaroslav ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
The thesis is mainly a structural engineering investigation of an old family house in Mladecko, Opava district. The whole object was measured, documented and examined; and after finding a series of defects, the aim of the theoretical part became to describe problematics of humidity and moisture in buildings. Moreover, because of the absence of previous documentation, there was a reason to carry out a brief historical study of the evolvement of rustic buildings, that became the second part of the theoretical work.
Computational design of ventilation system of air cooled generator
Kotalík, P. ; Ferfecki, Petr ; Novotný, Jaroslav ; Gabriel, Dušan
The results of computational design of ventilation system of air cooled generator were presented including the prediction of air flow in different branches and airgap between the stator and rotor. The simplified CFD models in software OpenFOAM were proposed.
Analytical solution of rotationally symmetric Stokes flow near corners
Burda, P. ; Novotný, Jaroslav ; Šístek, Jakub
We present analytical solution of the Stokes problem in rotationally symmetric domains. This is then used to find the asymptotic behaviour of the solution in the vicinity of corners, also for Navier-Stokes equations. We apply this to construct very precise numerical finite element solution.
Analytical solution of Stokes flow near corners and applications to numerical solution of Navier-Stokes equations with high precision
Burda, P. ; Novotný, Jaroslav ; Šístek, Jakub
We present analytical solution of the Stokes problem in 2D domains. This is then used to find the asymptotic behavior of the solution in the vicinity of corners, also for Navier-Stokes equations in 2D. We apply this to construct very precise numerical finite element solution.
Factors influencing quality and nutritive value of grass silages
NOVOTNÝ, Jaroslav
The paper analyzes the factors affecting the quality and nutritive value of wilted grasssilage. Grass silage sample were collected in the operating conditions for the firstmowing. Three groups were formed after 12 samples. The first group was the controlwithout using preservatives. The sekond group were included in the silage treated withbacterial agents. The third group included the bacterial-enzymetreated silage additives. There were no statistically signifiant differences in lactic acid kontent (P < 0.05) andvalues of thedegree of proteolysis (P < 0.05) between the kontrol group without the useof silage additives and the group, which was used for bacterial and bacterial-enzyme additives.
Implementace metody BDDC založená na forntálním a multifrontálním řešiči
Šístek, Jakub ; Novotný, Jaroslav ; Burda, Pavel ; Čertíková, Marta
A parallel implementation of the BDDC method is presented. It is based on frontal solver for subdomain problems, while the coarse problem is solved by a multifrontal algorithm. Results for an industrial problem of mine reel are included.
Modelování problémů proudění nestlačitelné tekutiny metodou konečných prvků
Burda, P. ; Novotný, Jaroslav ; Šístek, Jakub ; Damašek, Alexandr
We deal with modelling of flows in channels with abrupt changes of the diameter. We use a posteriori error estimates and adaptive strategy. We obtain solution with desired precision also in the vicinity of the corner, though there is a singularity.
Nedávný pohled na metodu BDDC a její paralelní implementaci
Šístek, Jakub ; Sousedík, Bedřich ; Čertíková, Marta ; Burda, P. ; Neumanová, E. ; Novotný, Jaroslav ; Damašek, Alexandr
A new view at the BDDC method was presented. Parallel implementation is described. Numerical results show effectiveness of the method.
