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.

Reinforcing UX Principles in Existing User Interfaces
Pilát, Peter ; Beran, Vítězslav (referee) ; Herout, Adam (advisor)
This thesis explains meaning of user experience, its main aspects, selected methodology, its integration into agile development process and what UX maturity level can be represented in real company. It also deals with analysis of selected existing user interfaces used for network print management and its end users. Prototyping and user testing methods are iteratively applied to these user interfaces. Evaluation of these methods concludes the thesis with a recommendation what UX processes should be integrated for future development of user interfaces in Y Soft.

Sport downhill cart for the disabled
Šantavý, Ivo ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This bachelor´s thesis deals with the development of a "Sport downhill cart for the disabled" prototype. This project was jointly inspired by Human Power Vehicles and by components from various industry sectors. After a description of the above mentioned vehicles, the work describes the successive development of the cart, including construction solution, and a component and frame modeling in the CAD system Autodesk Inventor. The total calculation of the entire "Sport downhill cart for the disabled" is presented in the conclusion.

Organic architecture and contemporary residential living
Čábelková Nahorniaková, Marcela ; Kyselka, Mojmír (referee) ; Budkeová, Branislava (referee) ; Glosová, Dagmar (referee) ; Menšíková, Naděžda (advisor)
Organic architecture is often used term especially in connection with the daring and experimental form. The exact definition or division is still missing. The founder of modern organic architecture is to be generally considered as Frank Loyd Wright. He was the man who created organic architecture and also made first definition in the early twentieth century, when formulating new architectural styles. Dissertation deals with insufficiently described problem of organic architecture. The main focus is on contemporary production of residential organic architecture in Central Europe. Especially on the particular realizations in Hungary, Czech Republic, Slovak Republic, Austria, Germany and Poland. Beside detail description of European realizations, the dissertation deals also with foundations of organic architecture in U.S.A. and important realizations here. Modern organic architecture primarily originated in the United States of America. The work presents most important contemporary realizations and architects creating resident living organic architecture in other countries around the world in order to complete the overview. The objective of dissertation was describing newest trends in designing buildings for living. Find position of organic architecture and give reasons for it´s increasing popularity, spread and necessity for new development in architecture according to the new trends. Organic architecture is an alternative way of contemporary residential living. It´s popularity is growing in last years in response to the development of modern technologies and materials, the need to protect our natural resources and also to the increasing negatives of globalization and to denial of local traditions and regional specificities. Aspects of organic forms were divided into three main groups according to their main characteristics: form, harmony and sustainable development. Another objective was find location of contemporary organic residential architecture in Czech Republic and abroad. It is rather spread all over the world than concentrated on certain places. Therefore I selected countries that are richer than the others on the occurrence of organic buildings. The objective was also to address architects, specialists, public and especially university teachers of architecture and students themselves. Communication with them was mainly connected with grant project in 2010. The theme of grant project was contemporary organic architecture in residential living. There were lectures about contemporary organic architecture and exhibition on the theme: Contemporary living organic architecture. The publication of the catalog was published under the title: Contemporary organic houses - Europe. I had the opportunity to visit a number of organic family houses abroad. Specifically houses in Slovakia, Hungary and Germany. Results of survey, which was realized by questions to owners and authors of chosen buildings, are included in dissertation. The mail results of dissertation are - make a detail review of organic architecture in residential living - define trends in contemporary organic architecture and residential living - obtain and process answers from owners and authors of chosen buildings within survey - analysis of organic house ( houses) in city planning and landscape - publication of catalogue focused on organic contemporary European houses - article about contemporary organic architecture and residential living will be published in 2012 on archiweb page
