The entry of a new technical journal on the market
Šplíchal, Jan ; Pálka, Peter (advisor) ; Pokorný, Jan (referee)
Cílem této práce je komplexní náhled na postupy a úkony nutné při nově vznikajícím odborném časopisu se zaměřením na skladbu obsahové části časopisu a multimediální přílohy. Pozornost je také věnována webové prezentaci titulu, která má velkou šanci do budoucna poskytnout, díky svým technologickým možnostem, papírové podobě časopisu zajímavé rozšíření a doplnění. Úvod obsahuje přehled současných vydavatelství působících v České republice a uveden je také přehled odborných počítačových periodik. Zmíněn je rovněž legislativní rámec a právní zabezpečení vydavatelské činnosti. Obsahem práce je také krátký historický pohled na distribuci v ČR a možnosti kompletace výtisků. Jádrem práce je zamyšlení nad obsahovou náplní časopisu, jeho rozdělení na tematické bloky a jednotlivé části. Neméně důležité multimediální příloze je věnována druhá polovina této stěžejní části, kde jsou popsány možnosti vkládání multimediálních příloh, jejich základní skladba a výhody. Závěrečná část se zaobírá možností webové prezentace časopisu. Webové stránky poskytují do budoucna vhodný způsob doplnění tištěného časopisu zejména svými technologickými možnostmi, které papírová forma nemůže poskytnout.

The use of floating suction dredger for cleaning and removal of natural sediment
Sedlecká, Šárka ; Pokorný, Jan (advisor) ; Petr, Petr (referee)
Unconventional technology called "wet method" is a gentle pumping and removal of undesirable sediments not only in ponds and streams, but also in shallow waters, canals, harbors, lakes, recreational water areas and other tanks, decorated in treatment technology and water purification. This is a floating suction dredger WATERMASTER CLASSIC III, which functions as a classic and dragline as one and due to various peripheral devices isvaried uses. This machine is also ideal for repairing the damage during floods because of its versatility.

Construction technology study of the construction of the bearing structure of manufacturing plant in Jihlava
Pokorný, Jan ; Liška, Pavel (referee) ; Kovářová, Barbora (advisor)
Company engaged in modernization of locomotive vehicles progressively modernizing their industrial estate. A big investment become realization of new industrial hall for vehicle coating, simultaneously with a reconstruction of neighbouring production hall and a new connection to the water main, gas main and a new transformer station. The bachelor thesis includes technological regulations of bored piles and for assembly upper prefabricated reinforced concrete construction of coating hall. Technological regulations are supplemented by draft of the suitable machinery, equipment of construction site and inspectional and trial plans, work safety, time schedule and comparison of two variants of the cranes and all will be feasible in terms of construction rate and financing.

Numerical modeling of the water cooled charge air cooler in/out chamber leading to development of the analytical model
Lasota, Martin ; Pavlica, Ondřej (referee) ; Pokorný, Jan (advisor)
Diploma thesis deals with numerical simulations of an air flow in a water cooled charge air cooler (WCAC), specifically with pressure drops in inlet/outlet chamber. The simulations have been performed in a proprietary software Star-CCM+. Physical phenomena have been solved by the Reynolds-averaged Navier-Stokes (RANS) equations and consequently a matrix of pressure drops for miscellaneous variations of chamber's geometry and the initial flow conditions has been created. Based on the CFD results, dependence between calculated pressure drops and changing parameters has been analyzed and finally a 1D solver has been developed and implemented into a software OpenModelica.

Numerical simulations of magnetoacoustic waves in solar corona
POKORNÝ, Jan
The topic of the master thesis are the numerical simulations of magnetoacoustic waves in the solar corona in relation to the reconnection of magnetic field. The first part is devoted to the basic description of the Sun, its atmosphere and the processes that occur in it. Other sections are devoted to the description of reconnection of magnetic field and the description of solar flares taking place in the solar corona in relation to the mechanisms of magnetic field reconnection. Then the attention is focused on plasma waves and oscilations. The last section aims to simulate the startup options of the reconnection of magnetic field by oscillations and waves in the Harris current-sheet. Numerical simulations are implemented in FLASH 3.3.

Application of thermal camera for analysis of heat
Palička, David ; Pokorný, Jan (referee) ; Lízal, František (advisor)
Within this bachelor degree thesis I have focused on the thermal losses from storage tanks serving as asphalt binders. I have used the theory of non-contact temperature measurements using a thermovision camera. In the first part of this document I deal with the history, theory and some basic principles of non-contact temperature measurements. In the second part I am examining the thermovision camera settings. The third part considers the function of the asphalt mixture production plant itself, as well as the function of storage tanks. In the last part of this thesis I analyze the results of the measurements. The goal of this analysis is to compare results of thermal losses from storage tanks heated with thermal oil, and storage tanks heated with an electrical thermocouple.

Analysis of possibilities of solution of buckling of a screw-shaped beam
Pokorný, Jan ; Fuis, Vladimír (referee) ; Burša, Jiří (advisor)
Bachelor’s thesis deals with the effect of the pretwist of a column on the increase in buckling load and also focuses on a column with rectangular cross section. This problem is divided into two main parts. The first one is represented by the column with a large thread pitch, the second one by a small thread pitch. The results are obtained by a numerical approach using MATLAB software. The verification is carried out via finite element software. The outcome of this thesis is plotting the ratio of the critical loads of the twisted and prismatic columns against the ratio of the side lengths of the rectangular cross section. The results are shown for both types of considered columns.
