Three - side gate with hydraulic open mechanism
Krůza, Libor ; Pokorný, Jan (referee) ; Kašpárek, Jaroslav (advisor)
The bachelor project deals with design solutions of the mechanism hydraulically open side gate. The side gate is part of a three-sided dump trailer. The tilting body is used for transport of the powdery materials. The main task of the mechanism is to open the side gate without a driver’s manual work. The side gate is hydraulic open.

Deposition of inhaled particles in a model of child lungs
Čederle, Jakub ; Pokorný, Jan (referee) ; Lízal, František (advisor)
This thesis presents a summary of research of deposition of inhaled particles in children’s respiratory system which was mainly conducted on realistic model of children's lungs. Experimental part introduces BUT model representing airways of 5-years-old child which served for measurements of regional deposition. Bachelor's thesis furthermore sums up basic knowledge of respiratory system and points out anatomical and physiological differences between children and adults in given field. There are described basic deposition mechanisms and their impact on aerosol therapy as well.

Use of the DIC method in solving basic problems of solid mechanics
Hrůza, Vlastimil ; Pokorný, Jan (referee) ; Ščerba, Bořek (advisor)
This bachelor’s theses deals with the solution of basic problems of solid mechanics using digital image correlation. The research part of the thesis presents some of the optical methods used for deformation measurement, digital image correlation in particular, whose history, principles, limitations and utilizations are described in detail. In the practical part of the theses, three experiments are carried out, which are then evaluated using digital image correlation and the results are compared with the created computational models. In the first experiment, strain on the tensile test specimens with notches is measured, the second experiment is focused on measuring strain when bending curved beams and in the final experiment, natural frequency of a fork produced by 3D printing is determined.

Low-cost sensors for measurement of particulate matter
Dvořáková, Michaela ; Pokorný, Jan (referee) ; Lízal, František (advisor)
This work focuses on the research and comparison of several types of low-cost sensors for measurement of particulate matter. It clarifies the principles of aerosol particles measurement and focuses on the reasons of using low-cost sensors. It provides basic information about the impact of aerosols on human health. The experimental part of this work compares quality of the obtained results considering the price of the respective devices.

Manipulator in the line for heating logs
Vítek, Jan ; Pokorný, Jan (referee) ; Pokorný, Přemysl (advisor)
This thesis concerns with construction design of manipulator. The purpose of the manipulator is to transport beech logs. It is a part of the production line for heating and steaming veneering of the logs before their subsequent processing. This thesis presents a new design solution. It offers detailed descriptions of the purpose of the construction and of individual functional assemblies. It also describes the means for operating the machine and the types of sensors used. Calculation of forces and reactions in the mechanism, based on a simplified load calculation model, constitutes an important part of the work. Design of key components of the machine is then based on the results of the analysis of the forces involved. The supplements of the thesis include photographs of the manipulator realization and selected technical design.
