Gears made by 3D printing
Bělota, Martin ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
In the course of this work, the issue of 3D printing focused on the production of gears is addressed. The goal is to create gears based on designed gear models using 3D FDM printing technology. The theoretical part of the work describes the technology of 3D printing, including materials used for printing and selected technologies of 3D printing. Furthermore, the parameters of spur and bevel gears are described in the work because the practical part deals with them. The practical part of the work focuses on the production of gears from design, construction, preparation of the production process to the printing of the prototype and finishing of the prototype.

Web design of a construction company
Ličman, Jan ; Šimáček, Ondřej (referee) ; Dohnal, Radek (advisor)
This diploma Thesis deals with problematics of web design in civil engineering. Specifically, it focuses on the web design of a projective construction office. The basic concepts relevant to the problematics are defined in the theoretical part of this Thesis. The practical part begins with initial analysis which consists of an opening workshop with a client, a survey and competition research. Based on the analysis findings, target group and project direction are set. Following these steps, the web design is created. It consists of several parts – generation of ideas and possible solutions, information architecture, sketching, prototyping, prototype testing and graphic design itselfs, which is output of this diploma Thesis.

Engines for Le Mans Series
Herman, Pavel ; Blaťák, Ondřej (referee) ; Svída, David (advisor)
This bachelor´s thesis deals with the overview of development the drive units, which are used by racing cars of Le Mans endurance series, mainly the race 24 hours of Le Mans. In the first part is outlined the general characteristic the series and the race 24 hours of Le Mans itself. There are briefly described the instructions and the most important technological limitations, observed by designers. The second part contains an owerview of racing cars engines, which are interesting from the historical point of view either by their construction or by achieved success. The last part is devoted to the constructional comparison of drive units of present participants the Le Mans series, their description and the important technical specifications.

Design of synchronous reluctance motor with permanent magnets
Knebl, Ladislav ; Huzlík, Rostislav (referee) ; Ondrůšek, Čestmír (advisor)
V dnešní době je kladen vysoký nárok na účinnost elektrických zařízení a to jak ze strany provozovatele, tak i legislativy. Nejlepší účinnosti dosahují synchronní motory s permanentními magnety umístěnými na povrchu rotoru (SMPM), se kterými lze i u malých motorů dosáhnout účinnosti nad 90%. Nicméně tyto motory jsou z důvodů použití magnetů ze vzácných zemin, např. NdFeB, drahé a jsou schopny provozu pouze s frekvenčním měničem. Z cenových důvodů jsou hledány levnější alternativy k SMPM motorům. Jedním z typů motorů, kterým lze SMPM nahradit je synchronní reluktanční motor s permanentními magnety (PMASR). Tento motor je cenově výhodnější, protože používá menší množství magnetů, při zachování podobných, mnohdy i lepších vlastností, nicméně neodpadá potřeba použití frekvenčního měniče. Navíc je zde možnost použití levnějších feritových magnetů a tím ještě výrazněji snížit cenu motoru. V této práci bude PMASR topologie popsána důkladněji včetně elektromagnetického návrhu metodou konečných prvků. Bude provedena i mechanická analýza zvoleného optimálního modelu. Výsledky dosažené metodou konečných prvků budou následně porovnány s analytickým modelem. Z navrženého modelu bude vyroben prototyp a naměřené výsledky budou porovnány s výpočty.

System for Quality Control Management of Devices
Černý, Lukáš ; Hrivňák, Ján (referee) ; Hynek, Jiří (advisor)
This diploma thesis describes both the theoretical and practical part of the process of design and implementation of interactive computer software for the~management of~the~quality control of the~devices, assigned by SIGMA GROUP a.s., more precisely its Energo division, which is engaged in the maintenance and repair of pumping equipment. The theoretical part explains the concept of user experience, its acquisition methods, specification of~requirements and interface design methods. The next part is focused on the description of the~formats used by common text editors. Within the theoretical part is described the design of the interactive application itself. In the practical part there is a description of the main parts of the system and the conclusions from the system testing.
