Preparation and application of PHA based nanofibres and nanoparticles
Linha, Vojtěch ; Skoumalová, Petra (referee) ; Márová, Ivana (advisor)
The goal of this thesis was to summarize basic options of fiber spinning and manufacturing and their usability in industry. Methods of nanofiber spinning are described in the teoretical part, alongside the materials used in experimental part. The experimental part was focused on creating of workflow of defined nanofibers in laboratory enviroment, the possible modification of nanofibers with aditives. The release of aditives from different nanofibers into different enviroments was measured.

SMS Enterprise Premises
Kopřivová, Nikola ; Šuhajdová, Eva (referee) ; Myslín, Jiří (advisor) ; Čuprová, Danuše (advisor)
The building for small and medium business is located on the outskirts of the city of Brno in Modřice. In close proximity there is a shopping center Olympia, Giga Sport and discount furniture. The building is designed as a compact mass, which is divided horizontally into two different sectors of manufacturing industry and administrative offices. The production hall is vertically extends through the first two floors and part of her administration is appropriate in the southern part of the building. In the northern part of the premises is located warehouses and production supply. The third floor is a separate space for administrative purposes with its own entrance from the eastern part. The building meets the standard for low power consumption and a flat roof can be used to store solar collectors for energy and hot water. Each location in the building is wheelchair solved. The facade is divided horizontally by three colors black, gray and white. Window are designed as french windows vertical contrast to the color of the facade. The building offers maximum versatility, functionality and potential jobs

Improvement of the LCV 20 Stator Manufacture with The CNC Horizontal Boring Machine ŠKODA FCW 150.
Mejzešová, Monika ; Ženožička, Petr (referee) ; Píška, Miroslav (advisor)
This diploma thesis deals with a production process cast body of the stator the in the company Papcel, a.s., Litovel. The first part is focused on the description of the current production process. The production is realized with several manufacturing machines and hand machining also. The second part analyzes available changes of the current technology and describes alternative procedures and production facilities. The CNC machine-tool ŠKODA FCW 150 seems to be the most effective way of production, which could increase the labor productivity, cut the share of manual works, reduce a risk of a human error and to increase the final product quality and accuracy. The final part of the thesis evaluates the machine and preparation times for a single production, including assembly operations and financial impacts of the investments on the company costs.

Efficiency Improvement Proposal of Production of Semi-Finished Products for Gun-Barrels
Zemánek, Patrik ; Botek, Jan (referee) ; Sedlák, Josef (advisor)
This thesis is focused for manufacturing of a gun barrels and his issues. In thesis is involved introducing of the company Česká zbrojovka a.s. and definition of hand fired guns. Written analysis present the state of a technological process and describe an individual phase of manufacturing of the semi-finished product of gun barrel and the following conclusion of a complex manufacturing of a gun barrel from the semi-finished product to the stand, when the gun barrel installed into the gun is. Subsequently are suggested possibly solutions of manufacturing rationalization and possibly purchasing of a new modern CNC machines. In the end is accomplished a technical-economic evaluation, which compares existing and suggesting of the technology.

The Study of Optimization of Production Process
Holík, Lukáš ; tesař, Rostislav (referee) ; Jurová, Marie (advisor)
The master thesis: „ The Study of Optimization of Production Process“ focouses on optimization of material flow to manufacturing department. First of all there will be shown theoretical approach corresponding with the thesis area and we will introduce production system and portfolio of products. Subsequently a real project will be analyzed and author will describe deficiencies in this project and system. Thanks to theoretical approach there will be found a different solution how to define new system without deficiencies. In the end the author will make a conclusion of newly found solution

Component technology design "injector cover" in condition of a small firm
Hampl, Petr ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
Processing completely producting technological documentation for production part “INJECTOR COVER” for firm BM SERVICE (formerly ČKD Hradec Králové), including time schedule production of parts (parts which past welding and machining create demanded component part) and calculation production costs. Solving production process is concepted in two variation (actual and forecast study) for machines which are sorted from existing machinery and from now proposed machines. Estimation is designed for firm conditions introducing to the production with view for qualifications of workers, convention in firm and equipment.

Design and Optimization of High-Torque Ferrite Assisted Synchronous Reluctance Motor
Knebl, Ladislav ; Rafajdus,, Pavol (referee) ; DUŠEK,, Jiří (referee) ; Vítek, Ondřej (advisor)
Vysokomomentový asistovaný synchronní reluktanční motor může být, soudě podle nízkého počtu publikovaných článků, stále považován za relativně málo prozkoumané téma výzkumu. Tato ale i další výhody, jako nízká výrobní cena a vysoká hustota výkonu poutají pozornost výzkumných pracovníků. Navzdory tomu, že tento druh motoru je zajímavější z pohledu konvenčních nebo vysokootáčkových aplikací, tak se i trakční aplikace dostávají do popředí s tím, jak jsou objevovány vlastnosti tohoto motoru. Tato práce se zaměřuje na návrh tohoto typu motoru pro pohon lodi, který je navržen aby dosahoval vysokého momentu při nízkých otáčkách. Aplikace je definována výkonem 55 kW při 150 otáčkách za minutu a použitím levných feritových magnetů s cílem nízké ceny motoru. Návrh motoru je úzce propojen s optimalizačními algoritmy aby bylo dosaženo co nejlepšího výkonu v daném objemu stroje. Navzdory tomu, že návrh samotný je velice zajímavým tématem, tak práce deklaruje další teze, které jsou rovněž zajímavé a důležité. Vzhledem k tomu, že je práce zaměřena i na optimalizaci, tak prvním cílem práce je porovnání různých optimalizačních metod. V této práci jsou nejenom že různé druhy optimalizačních algoritmů, samoorganizující migrující algoritmus a genetický algoritmus, porovnány, ale jsou zde porovnány i různé optimalizační metody. Metoda založená na definování preferenčního vektoru a ideální multi-objektivní metody jsou v rovněž v této práci srovnány. Tyto algoritmy jsou srovnány v případě více optimalizovaných parametrů. Dalším scénářem pro porovnání ideálních multi-objektivních algoritmů je ten s menším počtem parametrů. Posledním cílem práce je laboratorní měření navrženého optimalizovaného stroje, které rovněž představuje další set výzev v této práci, které jsou diskutovány v poslední kapitole této práce.
