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.

Lifting and handling equipment for aircraft overhead Accessories
Kaše, Vladimír ; Holub, Michal (referee) ; Pavlík, Jan (advisor)
The thesis is dealing with the design proposal of mobile handling equipment for the aircrafts´ overhead accessory. In its initial part it describes different types of manipulators in use, following by several possibilities how to solve the problematics. The main part of the thesis is focused on concrete solution and construction of such manipulating facility, including the strength and control calculations.

Geometrical concepts of perpendicularity and parallelism in 4th and 5th grade of primary school
Kopecká, Alena ; Slezáková, Jana (advisor) ; Jirotková, Darina (referee)
The diploma thesis is focused on pupils attending 4th and 5th grade in primary school. These children are observed for their knowledge of perpendicularity and parallelism and their ability to use it in practice. The theoretical part describes two geometrical terms - perpendicularity and parallelism. Other chapters describe different theories of learning, the process of knowledge construction and also the stages of language development in geometry. Furthermore the thesis explores the topic in state curriculum documents. The geometrical terms and their occurance, frequency and preparative tasks are searched in different textbooks. The practical part includes experiments based on qualitative research. The survey is conducted through a worksheet with different types of tasks which were chosen to test the participants' knowledge of above-mentioned terms. These experiments were recorded and analyzed by means of phenomena that appeared. The phenomena allowed me to answer the questions that were posed in the beginning of the research. Key words: perpendicularity, parallelism, preparative tasks, depth of knowledge, experiment
