Design of metasurfaces for advanced optical elements
Březina, Tomáš ; Kvapil, Michal (referee) ; Hrtoň, Martin (advisor)
Metasurfaces represent an intriguing class of materials with a wide range of promising applications, one of them being advanced planar optical elements for industrial production and imaging. The main goal of this thesis is to design such an optical element, namely a beam-shaper consisting of dielectric anostructures in HCTA (high constrast transmitarray) arrangement. The first part of this work introduces a simplified theoretical model of the optical response of building blocks that facilitates understanding of the basic functional mechanism behind the phase metasurfaces. To quantify the optical response of dielectric building blocks with enough precision, numerical FDTD simulations were employed. As a result, a database compatible with lithographic fabrication procedures was created. To find the phase distribution ensuring the desired beam-shaping function, two approaches were investigated and implemented: the semi-analytical method of geometric transformation and the iterative Gerchberg-Saxton algorithm. The final output of this work is then the distribution of building blocks within the metasurface that imprints into the impinging beam the previously calculated phase profile.

Image registration using optimization with automatic differentiation
Slavíček, David ; Kolář, Radim (referee) ; Vičar, Tomáš (advisor)
This thesis deals with image registration using optimization with automatic differentiation. In the teoretical part were decribed steps of image registration and possibilities of their realization. The practical part consists of design of algorithm for registration of afinely transformed images and implementation of it. Two modifications of the algorith were proposed. Database of xray images was designed. The algorithm was tested on this database.

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.

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.

Management Study of the Selected Group of Inventory
Podaná, Hana ; Mihalisko, Marek (referee) ; Jurová, Marie (advisor)
This work has been devoted to tailoring of inventory management model for a selected material group within company Tyco Electronics Czech, s.r.o. It focuses on three areas of purchasing, i.e. planning of purchases, material procurement and inventory management. This work analyses most painful problems and suggests walls how to overcome those problems. The main contribution of the work lies in material cost reduction and consequent volume reduction of capitalized inventories. Production down times based on the lack of packaging materials should be also reduced.

Dynamic Programming in Graph Algorithms
Biloš, Martin ; Křivka, Zbyněk (referee) ; Burgetová, Ivana (advisor)
This work is about graph algorithms, their use and the benefit of the optimization method of dynamic programming. This benefit is show to the user via the graphic application. Graph algorithms find use in many sectors of human activity. They are used in packet routing or, for example, navigation. There are three methods of graph algorithms used in this work. This problems are solved with classic and dynamic way and measured data are compared.
