Single Point Incremental Forming
Brabec, Martin ; Podaný, Kamil (referee) ; Peterková, Eva (advisor)
Incremental metal sheet forming has gone through a period of development and enjoys increased attention of industry for its unique benefits and properties. This work aims for an up to date state-of-the-art review of incremental metal sheet forming focused mainly on single point incremental forming appended by a review of used tools, machines and applications.

The Use of Project Management Tools in Practice
Brabec, Matěj ; Smolíková, Lenka (referee) ; Doskočil, Radek (advisor)
This bachelor thesis deals with the use of project management tools in practice, specifically on the example of creating a draft project plan for launching a new product on the market of TOPVET company. The first part of the bachelor thesis presents theoretical knowledge of project management. The next part deals with the analysis of the current state of company TOPVET and its surroundings. The last part describes the design of the project and its benefits.

The effect of production parameters on the plasticity of structural steel
Brabec, Martin ; Podaný, Kamil (referee) ; Peterková, Eva (advisor)
The master thesis deals with the influence of heat treatment and storage time on microstructure and mechanical properties of 26MnB5 steel, which is used in the production of tubular components in the quenched and tempered state. The objective was to increase the plasticity of the steel by the definition of new process parameters of the induction heat treatment line. New tempering diagrams of 26MnB5 steel for two various speeds of the heat treatment line were established and used to determine new tempering temperature and speed of the heat treatment line. Observation of the influence of storage time on mechanical properties of the steel did not reveal that it is liable to ageing.

The effect of temperature on the mechanical properties of greywacke
Brabec, Marek ; Horák, Vladislav (referee) ; Krmíček, Lukáš (advisor)
The author of this master's thesis studied the influence of high temperatures on Lower Carboniferous greywacke sampled in the Kobeřice quarry near Prostějov. Two sets of cylindrical bodies were produced, made of fine and relatively coarse-grained greywacke. The samples were then fired at temperatures up to 1200 °C. Thermally altered samples were then studied in laboratory using rock mechanics and petrography methods. Results of the study were then carefully interpreted to determine relations between the rock parameters, structural changes and the firing temperature. The master's thesis also contains a brief insight into rock thermomechanics, necessary theoretical background to the used methods and geological context of the Drahany Upland, where the samples of the tested greywacke were taken.

Estimates of covariances for estimated concentration field
Brabec, Marek ; Malý, Marek ; Malá, Ivana
Developing estimation of relevant covariance matrix entries for the spatial model as a necessary part for computing pointwise standard errors (as formalizations of local uncertainty for the gridded estimates). They, in turn are precursors for optimization algorithms aimed at measurement network design problems (location of added and/or deleted measurement points).

Perspektivy rozvoje elektricky poháněných vozidel kategorie M
BRABEC, Martin
The number of cars with the combustion engines which they move on the roads all around the world is alarming. It is impossible to overlook the incidental impacts of this expansion out of consideration for this number. The most perceptible impact is on our environment where we live. The air, especially in the cities, is not what it once was. Alternative-fuel vehicles start to be used because of these impacts and we believe in improvement. One of the solutions is using electric vehicles (EV). The request of this thesis is: The perspectives of the electric vehicles' development of category M. The main goal of this thesis was the determination of the factors which have some effect on the development of electromobility. Afterwards it was important to do the practical verification of chosen electric vehicles (EV) on the same road and the evaluation of the figures gained during the measuring. The other operation factors were also verified with these problems.

DC 5.3 Fundamental large scale statistical model
Brabec, Marek ; Malý, Marek ; Malá, I. ; Hladká, Adéla
This document describes suite of fundamental large-scale statistical models developed from data provided by CHMI (Czech Hydrometeorological Institute). The models were constructed in several variants, differing in complexity, detail and computational demands. Spatial models will be, after some further developments and modifications (necessary not only from the natural model evolution but also due to systematic changes brought e.g. by covid outbreak influences) used as the main input for optimization algorithms constructed for selection of measurement stations on the principles of statistical design theory and methods.
