Modification the plan of construction of linear structures
Mudrák, Miroslav ; Kocanda,, Pavel (referee) ; Nový, Martin (advisor)
Submitted thesis deals with planning of an implementation of a linear construction by using the contract conditions. The theoretical describes the topics of project management, engineering, procurement and traffic politics of Czech Republic. It also describes the history, status and development of the highway network. In the end there is introduced the modernized section of the D1 highway. The practical part deals with the application of the modified project Modernization solutions to the D1 highway - section 22 by introducing a shift operation during the construction. It solves the impact of shift work on phasing construction schedule, financial plan and compares the positive aspects of the solutions against the negative ones. In conclusion there is an evaluation effectiveness of the actual and modified variants of the construction.

Drive Vertical Saddle of Machining Centre by Linear Motor
Zapletal, Radek ; Andrýsek, Radim (referee) ; Foller, Bronislav (advisor)
The diploma dissertation deals with the mechanism of vertical movement of a saddle of high-speed machining centre which is made by the Trimill company. The movement of vertical alloy saddle is solved by ball screw. The solution could be improved by replacing the ball screw by linear motor. This will dramatically improve the dynamics of the movement of the vertical saddle. In addition, if the weight is compensated by pneumatic relief and the construction is welded, the dynamics will further improve.

Algorithms for various geometric problems over zonotopes and their applications in optimization and data analysis
Rada, Miroslav ; Černý, Michal (advisor) ; Vlach, Milan (referee) ; Kopa, Miloš (referee)
The thesis unifies the most important author's results in the field of algorithms concerning zonotopes and their applications in optimization and statistics. The computational-geometric results consist of a new compact output-sensitive algorithm for enumerating vertices of a zonotope, which outperforms the rival algorithm with the same complexity-theoretic properties both theoretically and empirically, and a polynomial algorithm for arbitrarily precise approximation of a zonotope with the Löwner-John ellipsoid. In the application area, the thesis presents a result, which connects linear regression model with interval outputs with the zonotope matters. The usage of presented geometric algorithms for solving a nonconvex optimisation problem is also discussed.

Methodology for modeling of dynamic processes by finite element method - Phase I
Kolman, Radek ; Gabriel, Dušan ; Červ, Jan ; Plešek, Jiří
In the report, the using of explicit finite element analysis for solving wave propagation problems in solids is presented in depth. Its grid and full dispersion analysis is given with the influence of mesh size and time step size. Conclusion of the report summarizes criteria for mesh size and time step size settings so that dispersion errors do not exceed permissible values.

Design of a three-axis manipulator
Vojtěch, Michael ; Tůma, Jiří (referee) ; Holub, Michal (advisor)
The goal of master’s thesis is design of a three-axis manipulator working as x-ray unit. Axis include one rotary and two liner. The work is based on the existing manipulator and the goals are reducing vertical installation space, weight reduction, increasing accuracy and repeatability. Creating 3D model with computational report from available components. There is resulting variant solved with linear motor in this thesis with that there is indicated alternative variant but not dealt with in detail.

Graphs in didactics of mathematics
Lacková, Kateřina ; Hejný, Milan (advisor) ; Jirotková, Darina (referee)
Thesis is of an experimental kind with the possible application to ordináty education. It deals with the implementation of graph theory into education. Using graphs theory it presents briefly different a set of problems and particularly elaborate so called equation-arrow graph aimed to early graders. The core of the thesis is experiment done with second graders. Experiment is described and analyzed. The main concern is given to solving strategies of pupils. The obtained results might be applied to education not only in grade 2.

Optimization of children food at the camp
Kadlecová, Kateřina ; Skočdopolová, Veronika (advisor) ; Kobzareva, Maria (referee)
This bachelor's thesis focuses on a diet optimization of the children's summer camp cuisine in accordance with the standards placed on the nutritional food composition as well as on the equipment and possibilities of the local kitchen. The theoretical part of the thesis includes the description and the structure of the operational research problem. Whereas the aim of the empirical part was to model the problem as a task of the linear as well as the goal programming. Both these tasks were solved in the LINGO software. The results were exported into MS Excel and then added to the text of the present thesis as the tables of resulting menus. The present thesis identifies the nutritional value and composition of 43 dishes. The list of these dishes served as the input file used for the modelations mentioned above.

Menu optimization for school cafeteria
Vlačihová, Martina ; Princ, Peter (advisor) ; Chrobok, Viktor (referee)
This bachelor thesis deals with the application of mathematical programming in real data application. Specifically, it is nutritional problem that is defined in the environment of school cafeteria. The main topic is a compilation of the school menus. There are four menus that consist of twenty meals. There are many limitations which have to be observed. These limitations are based on the requirements of the Ministry of Health of the Czech Republic. The model is described with the linear programming and is solved by the program LINGO.

Numerical Method of Additive Noise Filtration by Means of Adaptive Filter in Image Processing
Venclovský, Jakub ; Druckmüller, Miloslav (referee) ; Štarha, Pavel (advisor)
This master’s thesis deals with issues, which are suitable to solve by the method of adaptive filtering of additive noise in image processing. It deduces an algorithm of the adaptive filtering method. Then it studies properties of this filter. In the end it applies deduced algorithm on a particular picture and compares the results with linear filtering.

Prediction of fluids temperature profiles in heat exchanger
Havelková, Pavla ; Kilkovský, Bohuslav (referee) ; Jegla, Zdeněk (advisor)
This master’s thesis is focused on the description and processing of the cell method, which is generally recommended for prediction of fluids temperature profiles in heat exchanger. In the thesis the basic equations for calculating heat transfer are presented and is also described the current situation in the field of computational prediction of fluids temperature profiles in heat exchangers. The cell method is solved by using the software Maple and is applied to the specific case of industrial heat exchangers. The results obtained by the cell method are compared with the results obtained by educational version of software HTRI Xchanger Suite. By this comparison explicitness of the cell method is assessed.
