Inner geometry optimization of flat-panel photobioreactor
Hlaváč, Ivan ; Babička Fialová, Dominika (referee) ; Rebej, Miroslav (advisor)
This master thesis focus on optimatization of flat-panel photobioreactor. The optimatization was performed using CFD models and Design of experiement. The CFD model used for the optimatizaion was before performing the experiment validated with real experiment data. Hydrodynamic parameters affecting microalgae yield were monitored during CFD calculations. They were: gas holdup, gas velocity, turbulent kinetic energy, dead zone ratio. interfacial area and shear stress.The photobioreactor with a stirrer and with vertical baffles, which were selected based on research, were compared. The higher values of hydrodynamic parameters were reached with a stirrer. Baffels were evaluated as more suitable for microalgae, which are more sensitive to shear stress.

Design of material handling between the planned interimwarehouse and welding shops using dynamic simulation
Vícha, Ondřej ; Urbánek, Michal (referee) ; Hloska, Jiří (advisor)
This master thesis deals with optimizing material and information flow between the production plants and warehouses during the reconstruction of the manufacturing plant of Schäfer in Hranice na Moravě. At first, a theoretical introduction to the issues of inter-company transport services is presented. This introduction is followed by an analysis of the current state of material and information flow at the manufacturing plant. The practical part of the thesis consists of a simulation model made in the Tecnomatix plant simulation program. This simulation model includes the plant's current and future states and a layout of future material flow between the welding shops and warehouses. It also contains a conceptual design of the material flow. The optimization is conducted using a matrix of experiments, which are subsequently evaluated. In the end, the most optimal solution for material and information flow is developed and suggested.

Stock portfolio strategy and analysis of its return and risk
PERNÍK, Jan
This study focuses on stock portfolio construction strategies to identify optimal approaches for short-term investments and to assess the trade-off between risk and return. One of the five portfolios was constructed by analysing undervalued stocks using the discounted future free cash flow method, which is described in detail in the study. The paper compares the portfolios with their alternatives calculated by maximizing the Sharpe ratio. We evaluate the risk and performance of the portfolios using the Sharpe ratio, Traynor ratio, Jensen's alpha, and Information ratio to determine the effectiveness of the strategies and their applicability in real scenarios. Finally, we discuss whether optimization is a useful tool in portfolio construction.

New Areas of the Ultrasonic Application in Microelectronics Technology
Buršík, Martin ; Pietriková, Alena (referee) ; Králová,, Iva (referee) ; Szendiuch, Ivan (advisor)
Doctoral thesis deals with the deposition of special thixotropic materials for microelectronic technology. The aim of the work is the development of the new method optimizing the dosing process in order to achieve a print resolution of better than 100 microns. The work includes the development of a special dispensing head (UZD) using the influence of ultrasonic energy. These results demonstrate the possibility of a newly developed method that is able to print thixotropic materials with a resolution of 65 microns. Compared to other methods achieves these results with the commonly used materials for thick film technology with particle size up to 5 microns.

Production process optimization
Habásko, Jakub ; Koška, Petr (referee) ; Fiala, Alois (advisor)
HABÁSKO Jakub: Production process optimization. The Master´s thesis of Master degree, second grade, school year 2008/2009, FME Brno University of Technology, Institute of Metrology and Quality Assurance Testing, October 2009, pages 68, pictures 40, tables 2, supplements 4. The project elaborated in frame of the Master degree, study branch Metrology and Quality Assurance Testing. This Master´s thesis deals with optimization of process plan. In virtue of submission was created an analysis present condition using of statistical methods and it was created suitable statistical methods applicable in production organization. Then is here described the problem of brazing bells, because in this place is originating the most of uptightness. Then the thesis brings recommendation and findings, which can help with optimization this process.

Stuff Placing Optimization for Transport
Vacek, Michal ; Smrčka, Aleš (referee) ; Křena, Bohuslav (advisor)
This bachelor thesis treats of application of stuff placing optimization for transport. Application is developed in cooperation with Škoda Auto a.s., which solves the problem of transport materials in containers from their factories to assembly halls abroad. It describes an application analysis, a plan and an implementation. Application consist of two parts. The first computes the optimalization - it selects subset from set of moduls (boxes) and it locates this boxes to a container. The second part of application display the stuff placing. The part of this bachelor thesis is also set of agnated optimalization methods, mainly Knapsack and Bin-packing problem.

Optimization of network flows
Rychtář, Adam ; Hrabec, Dušan (referee) ; Popela, Pavel (advisor)
This bachelor thesis focuses on the assigment of waste flows to specific producer for each edge andaplication on real model which maps the Czech Republic and the model is applied to real data of the Czech Republic. The goal is to determine variance of the expenses for each producer subject to changes in waste processing requirements. Then, the solution impacts and bottlenecks are analysed. The suitable optmization models is formulated and computations are realizaed in GAMS.
