Design and optimization of hydrostatic pocket space
Minář, Petr ; Pavlík, Jan (referee) ; Blecha, Petr (advisor)
This diploma thesis deals with an optimization of hydrostatic slide of the large-portal gantry machine FRU (TOS Kuřim). First part of the thesis concerns with an analysis of the current practice in hydrostatic guides in the field of heavy gantry machines, an usage of alternative materials for a construction of carrying parts of machines, and possibilities of current simulation methods. Aim of the second part of this thesis is a brief clarification of the principle of mathematical optimization, and creation of general methodology of construction optimization by means of system analysis. Optimization calculations were processed by ANSYS Workbench 11.0. There is achieved adjusted and optimized design of the hydrostatic slide as the result of the thesis. Moreover, the comparison of key deformations was added. Created methodology is applicable in both an area of construction of gantry machines, and a wide spectrum of construction fields.

Optimization of an aircraft wing rib
Kopřiva, Lubomír ; Suchánek, Miroslav (referee) ; Petruška, Jindřich (advisor)
Topology optimization is a method providing new direction in designing of a technical objects. The aim of topology optimization is to find optimal distribution of material in design space. This diploma thesis is focused on optimization of aircraft wing rib num.6 of the airplane EV-55 using a software HW/Optistruct 7.0 implemented in a software package HyperWorks 7.0. The optimization of the rib was calculated under four different load cases. Resulting shapes of the rib were then tested by strenght calculations in software ANSYS 10.0. Finally, the obtained data of weights of optimized ribs were compared with the weight of the original rib.

Preconditions for innovative technologies of stand establishment of field crops
Vach, Milan ; Javůrek, Miloslav
This methodology includes the contemporary knowledge on the newest developmental directions of stand establishment of field crops. The attention is focused on minimization and conservation soil tillage and on their influence of the soil properties. Site, agronomical and machine preconditions are evaluated in details for new unconventional technologies of stand establishment of field crops in different soil and climatic conditions of the Czech Republic.

On the Minimization of Specific Learning Problems in Elementary School Students
BAŤKOVÁ, Anna
This study addresses the problems of specific learning disorders in elementary school children. It attempts to elucidate individual types of disorders and their most common symptoms in children. Furthermore, the work describes well known theories of the causes of specific learning disorders, their diagnostics, and primary ways leading towards minimization and correction of disorders. The whole study is divided into four chapters. Individual chapters are based on the best known knowledge in the area of specific learning disorders. The first chapter explores the causes of disorders, i.e. the theories attempting to explain specific learning disorders from the viewpoints of genetics, brain disorders, faulty information processing, light mental dysfunctions and last but not least {--} the environmental effects. The next chapter classifies and explains individual diagnostic procedures and tests needed before establishing child{\crq}s diagnosis. The third chapter addresses individual specific learning disorders. It describes their definitions and main symptoms The last chapter is devoted to disorders minimization. There we introduce Individual Educational Plan as well as the exercises appropriate to individual disorders.
