Similarities in chaotic behavior of Lorenz 05 model and ECMWF models
Bednář, Hynek ; Raidl, Aleš (advisor) ; Jaňour, Zbyněk (referee) ; Pokorný, Pavel (referee)
This thesis tests the ability of the Lorenz's (2005) chaotic model to simulate predictability curve of the ECMWF model calculated from data over the 1986 to 2011 period and demonstrates similarity of the predictability curves for the Lorenz's model with N = 90 variables. This thesis also tests approximations of predictability curves and their differentials, aiming to correct the ECMWF model estimated parameters and thus allow for estimation of the largest Lyapunov exponent, model error and limit value of the predictability curve. The correction is based on comparing the parameters estimated for the Lorenz's and ECMWF and on comparison with the largest Lyapunov exponent (λ=0,35 day-1 ) and limit value of the predictability curve (E∞=8,2) of the Lorenz's model. Parameters are calculated from approximations made by the Quadratic hypothesis with and without model error, as well as by Logarithmic and General hypotheses and by hyperbolic tangent employing corrections with and without model error. Average value of the largest Lyapunov exponent is estimated to be λ=0,37 day-1 for the ECMWF model, limit values of the predictability curves are estimated with lower theoretically derived values and new approach of calculation of model error based on comparison of models is presented.
Long-distance belt conveyance
Kulich, Stanislav ; Pokorný, Přemysl (referee) ; Zeizinger, Lukáš (advisor)
The purpose of my bachelor thesis was a research of devices similar to long-distance belt transport. However, the greatest emphasis is placed on the long-distance belt transport method. Following is a detailed description of each component of the device. Furthermore, it deals with functional calculation according to the assignment of bachelor thesis and strength check of selected elements. The last chapter is a proposal and justification of used components according to the results of calculations for this type of belt conveyor. Part of the thesis is the design of the overall device assembly.

Belt conveyor - tolerance analysis
Man, Lukáš ; Pokorný, Přemysl (referee) ; Zeizinger, Lukáš (advisor)
The Thesis deals with the tolerance analysis of the factors entering the long-distance belt conveyor of wet sand transport. The Thesis contains a critical research of similar belt conveyors of long-distance transport and a description of main parts of long-distance belt transport. Furthermore, the Thesis includes a calculation according to CSN ISO 5048 and all the standards related to this standard.
Barrel handling equipment
Dostál, Martin ; Pokorný, Přemysl (referee) ; Hloušek, David (advisor)
The primary content of this work is a conceptual design of a manipulative device for tin barrels, with its characteristic parameters. The model design was completed in accordance with the gathered information from the critical research of comparable devices available on the market. Ultimately, the model concept is focused on improving the market devices’ deficiencies. The manipulative device model was composed in Autodesk Inventor 2018 application and subsequently subdued to testing calculations. The entire model construction is chiefly welded. Therefore, the majority of the calculations is concerned with the solidity control of the welds.
Conception of horizontal wood splitting device
Mikl, Marek ; Hloušek, David (referee) ; Pokorný, Přemysl (advisor)
The aim of the bachelor thesis is a brief research of wood splitting machines and splitting tools, then it was the task to create own design of the horizontal wood splitting machine with the use of splitting grid according to the given parameters. The thesis is divided into four chapters. In the first chapter, the research of splitting machines was solved, in the second chapter the machine design wich was made itself, in the third chapter the strength analysis of important machine parts and in the last part the control functional calculations were made.
Conception of a conical splitter for wood
Stejskal, Jan ; Pokorný, Přemysl (referee) ; Hloušek, David (advisor)
This bachelor thesis consists of an introductory research part and a structural draft of a conical wood splitter with typed technical parameters and maximal log length and width. The thesis contains computing and strength examination of chosen components and final evaluation of designed construction from the law standards viewpoint.
Belt conveyors - special constructions
Hejl, Radek ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
