Snížení výrobního taktu na montážní lince / Reducing production cycle on the assembly line

Brožek, Michal January 2013 (has links)
The master’s thesis deals with the reduction of the production cycle at the assembly line of pumps in a particular company. The first part of the thesis is dedicated to introducing the company's history, products, and selected economic indicators. The following part is a theoretical analysis of types of assembly lines, their characteristics and methods for determining the consumption standards of time. The practical part analyzes time efficiency of a specific assembly line. The results of the analysis are presented in table and graphs based on three proposals that are designed to reduce the production cycle. The final part provides techno-economic overview and valuation of improvements designed according to the key indicators presented in the thesis.

Návrh racionalizace montážní linky sestav pro tepelné výměníky / Proposal for the rationalization of assembly line for the heat exchanger sets

Růžička, Lukáš January 2015 (has links)
The objective of the thesis is rationalization of current process of assembling of manifold assemblies from the reduction of operating costs point of view. The reason for rationalization is uncompetitiveness of actual solution due to high manufacturing cost of manifold assemblies coming from this process. After analysis of current operations, taking into account presumed production plan, the capacitive calculation of assembly line was done. Then alternative solutions were proposed based on above mentioned criterion, and from these the optimal variant was picked and developed. The assessment of resultant solution was done in the end.

Optická linka pro přenos vysokofrekvenčního signálu / RF analog fiber optic link

Kelbler, Petr January 2017 (has links)
This thesis analyzes the problem of design analog fiber optic link for transmission high frequency signals. Analog fiber optic link will be used in system for detection and localization a partial discharge activity MOSAD-PD-UHF, where will replace existing solution with coaxial cables, which is not appropriate for highly noise environment. MOSAD-PD-UHF system is developed in department of theoretical and experimental electrical engineering. At the first, MOSAD-PD-UHF system and individual parts of optical chain are theoretical described. In following part are compared a few commercially available analog fiber optic link and design of chosen transmit and receive module are described. . The thesis final part deals with construction of optical link and measured parameters are discussed.

Účinné intervence v rámci chatové krizové pomoci / Effective intervention in Chat counselling

Švadlenková, Lada January 2019 (has links)
This master's thesis studies effective intervention in chat-based crisis support. This topic is especially relevant, as children, adolescents and young adults have been becoming more interested in such services in the Czech Republic. The theoretical part provides a window into the field of crisis support and elaborates on details of crisis intervention. It presents selected models, approaches, methods, and techniques of crisis intervention. The thesis also describes social support, effectivity, and effective intervention and connects these issues with the topic of crisis intervention. The main aim of this part is to focus on chat-based crisis intervention and its specific features when concerning children and young adults. The empirical part presents a mixed methods study conducted in the Safety line organization, which operates an important nation-wide hotline for children and young adults. In the study, clients and consultants were asked to evaluate the conversation that had just ended by filling out a questionnaire. The chat records were then analyzed in the next part of the study. Key words chat-based crisis intervention, chat counselling, children, adolescents, young adults, effectivity, effective approaches, Safety line / Child Helpline
