Design and Simulation of Micro-Bolometer in MEMS Technology
Svatoš, Vojtěch ; Pekárek, Jan (referee) ; Hubálek, Jaromír (advisor)
Tato diplomová práce zkoumá problematiku detektoru infračerveného záření nazývaného bolometr. Cílem je pokrok v detekci infračerveného záření použitím odlišné absorpční vrstvy modifikovanou karbonovými nanotrubicemi. V teoretické části jsou uvedeny základní fyzikální pojmy z problematiky teplotního managmentu a základních fyzikálních vztahů bolometru. Design bolometru je představen a popsán. Teplotně mechanické simulace předvídají chování bolometru při detekci infračerveného záření. PSpice model je vytvořen a kombinuje termální a elektrické vlastnosti čipu bolometru. Dále je uveden proces výroby bolometru, které je detailně popsán.

Rationalization of production of digital receiver
Polák, Martin ; Maruška, Josef (referee) ; Špinka, Jiří (advisor)
This diploma thesis deals with topics related to optimalization and increases quality production in the electronics industry. Project purpose was to analyze process production manufacturing digital receiver in specific situation applied upon multinational company. Main part mine work was build-up FMEA analysis and creation control plan production line. For optimize production flow was application method lean production and for department material supply method KANBAN. This diploma thesis has been written within cooperation of Celestica Ráječko company where I have picked up data and knowledge to above-mentioned topic.

Analysis and optimization of the production system using computer simulation
Vaďura, Pavel ; Knoflíček, Radek (referee) ; Simeonovová, Ivana (advisor)
This bachelor thesis focuses on the process of the creation of a simulation model followed by dissimulation of this model, and finally optimalization of the system using the results of the simulation. The aim is to clarify basic terms about production with consequential usage of simulation models and their application in the production proces. Next, the creation of the simulation model in the simulation software Factor/AIM is explained and illustratively demonstrated. The first part of the bachelor thesis deals with theoretical information about the production proces, division and creation of the simulation model and it analysis this model with the purpose of finding narrow places and suggesting its optimalization. This simulation proces is simplified version of the manufacture of seamless pipes.

Technological design of a manufacturing process modernization
Vaverka, Jiří ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
The topic of this thesis is to design the modernization process. The aim of this work the design of new machines for a particular component, which would replace the existing ma-chinery used in company-tion in which the component is produced. Introduction is focused on the description of the company and selected components for which it is evaluated di-mensioning, tolerance, functionality and material. The following describes the current ma-chinery engineering company and then are selected machines in two variants, which would replace the original equipment. With these new machines is a technical documentation and is evaluated modernization and environmental concerns. At the end of the re-evaluated results that modernization is beneficial or not.
