Conveyor Inverter - Design Lifting Mechanism
Zálešák, Martin ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
I am concern with a proposal of conceptual solution of Conveyor Inverter in my bachelor work. This Conveyor Inverter is used for the change of the direction europallet about 90° between roller and chain conveyor according to given technical parameters. My bachelor work contains complete 3D proposal, constructional and functional solutions which are based on checking calculations. Lifting of the Conveyor Inverter is done using a leverage mechanism of electric motor.

Combined heat and power generation
Hlaváč, Ivan ; Zálešák, Martin (referee) ; Klimeš, Lubomír (advisor)
The bachelor thesis deals with the power generation by means of a combined gas-steam cycle. In the first part of the work, an overview and description of the combined cycle as well as of the Brayton cycle and the Rankine cycle are provided. The second part of the work focuses in the thermal analysis of the cycles. As a part of the work, a computer program was created, which allows for such thermal analysis of the combined cycle.

Continuous vertical conveyor for transport the goods
Zálešák, Martin ; Bukovský, Radim (referee) ; Kašpárek, Jaroslav (advisor)
This diploma thesis deals with the existing of transportation unit products and designing of a better conceptual solution of continuous elevator with fixed section of a gravity and roller conveyor. This type of conveyor is specified mainly for the transport of boxed products from the lower floor to the another. The diploma thesis is substantiate by the proposal of assemblies machines. It includes a complete 3D design, engineering and functional solution that is supported by basic strength and the check calculations. The attachments consist of the drawings of the proposed facility.

Computational tool for fluid flow of gases through nozzles
Kozáková, Kamila ; Zálešák, Martin (referee) ; Klimeš, Lubomír (advisor)
This bachelor's thesis deals with thermodynamic relations of one-dimensional, adiabatic and steady flow through the duct. Thermodynamic terms, equations and principles, required for understanding the problems of fluid flow, are summed at the beginning. The greatest attention is paid to step-by-step solution of each case, which can occur. These analyses were implemented in a software for solving thermodynamic problems. Scripts and the graphical user interface were created in a programming language Python using its libraries. Last part of this work is focused on evaluating and testing problems of fluid flow through the ducts.

Thermal radiation in real life
Kalus, Petr ; Zálešák, Martin (referee) ; Klimeš, Lubomír (advisor)
This bachelor's thesis deals with the impact of heat transfer by radiation on the life around us. The research part summarizes the fundamental laws and concepts necessary for understanding the given issue. Furthermore, it describes and analyzes phenomena in everyday life where radiation is dominant. The greatest attention has been devoted to solar radiation, followed by the greenhouse effect, along with its influence on global warming. The thesis also includes a procedure for calculating heat transfer by radiation between two surfaces, based on which a Python script was written. Subsequently, a standalone application with a graphical interface was developed. The conclusion of the thesis focuses on describing the software development process and provides examples of test cases in thermomechanics.
