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.

SELF HARM IN ADOLESCENCE
BOBÁKOVÁ, Lenka
The work deals with self-harm as a maladaptive coping strategy. Emphasis is placed on adolescence as a risk period and on youth subcultures as a risk environment for emergence of this phenomenon. Attention is also paid to the internet and the real environment and their role in self-harm behavior. The aim was to identify possible causes of adolescent self-harm, who are part of the Emo subculture and any effect of the subculture of self-harm behaviors. Another objective was to find out where asolescents learned about this behavior and what is the role of ?social contagion?. The research was conducted qualitatively. Data were collected through semi-structured online interviews. These were conducted with four girls aged 13?15 years, who identify with the risk Emo subculture and have personal experience with self-harm. The data was then compiled into case studies of individual respondents. The research results showed that the causes of adolescent self-harm respondents are individual and there are always the role of several factors. Among these are: complicated relationships at home, problems at school, depression, loneliness and problematic relationship to own body. A direct link between the Emo subculture and self-harm, I didn´t discover. All respondents denied the influence of subculture. However, concerning the ?social contagion? self-harm behavior, this played the specific role by all respondents.
