Software support of education in cryptography area based on elliptic curves
Szturc, Jakub ; Sobotka, Jiří (referee) ; Burda, Karel (advisor)
The master‘s thesis is focusing on cryptography based on elliptical curves consists of four main parts. The first part provides an overview of the basic cryptographic and mathematical concepts. A key element of this work is the second part which are described in detail the mechanisms of counting two points on elliptic curve and counting point to themselves over the various fields. On this mechanism is based almost the entire issue. In the third section provides the best-known algorithms and protocols for key exchange, encryption and digital signature. The goal of this paper is to devise software to support teaching. This material is created as a web presentation, which described the theoretical foundations and the main characteristics of cryptosystems based on elliptical curves. The whole issue is supported by practical examples of calculations examples, there are also examples for independent work. Additionally, java applets are prepared that allow an interactive opportunity to try the basic parameters of curves, or verify the calculations.

Production of the Aluminium Bodies for the Oil Filter on a CNC Machine
Samek, Ivan ; Kolář, Ladislav (referee) ; Kalivoda, Milan (advisor)
The main theme of this bachelor's thesis is the production of aluminum housing for the oil filter module on a CNC machine. The work includes an introduction to its casting, a brief acquaintance with the various components of which the oil module consists, a description of the function of the oil module and a selection of CNC machine and the tools. The work also includes production process, instruction cards and drawings. Finally here is NC program according to which the functioning unit was produced. In the conclusion of the bachelor's thesis there follows an economic evaluation.

Designing of equipments for machining of high pressure pump housing.
Trutna, Pavel ; Janský, Milan (referee) ; Zemčík, Oskar (advisor)
The goal of this work was engeneering of new equipment for cutting operation in focus on new type of High Pressure Pumps CP3. Based on criteria from point of view of ergonomics, machining, shape of the housing and costs, equipment has been engeneered which allows to clamp and finish cutting of the required surface on the housing. Equipment designing has been perfomed in 3D CAD software which is able to provide with drawings and 3D data.

Body manufacture of a key lock
Leden, Pavel ; Madaj, Martin (referee) ; Kalivoda, Milan (advisor)
The diploma thesis is focused on the production of body for cylinder locks. This is production of very small and accurate parts. In the first part there is described the function of the lock, the sort of cylinder locks, their components and the basic types of safety elements. The second part is focused on the production of given type of body. The thesis deals with either existing production technology or proposals of possible innovation. This firstly consists in new organization of manufacturing operations. At the close we can find comparison of existing technology and new proposal.

Discretely normed orders of quaternionic algebras
Horníček, Jan ; Skula, Ladislav (referee) ; Kureš, Miroslav (advisor)
Tato práce shrnuje autorův výzkum v oblasti teorie kvaternionových algeber, jejich izomorfismů a maximálních řádů. Nový úhel pohledu na tuto problematiku je umožněn využitím pojmu diskrétní normy. Za hlavní výsledky práce je možná považovat důkaz jednoznačnosti diskrétní normy pro celá čísla, kvadratická rozšíření těles a řády kvaternionových algeber. Dále větu, která umožňuje mezi dvěma kvaternionovými algebrami konstruovat izomorfismy explicitně vyjádřené v maticovém tvaru. A v neposlední řadě důkaz existence nekonečně mnoha různých maximálních řádů kvaternionové algebry. Výsledky uvedené v této diplomové práci budou dále publikovány ve vědeckém článku.

Conception of an Object as a Complex of Perceptions in David Hume's Philosophy
Fršlínek, Jan ; Hill, James (advisor) ; Palkoska, Jan (referee)
Práce pojednává o objektu (jakožto komplexu percepcí) a s daným tématem souvisejícími otázkami v kontextu filosofie Davida Huma, jak je obsažena především v první knize jeho díla Treatise of Human Nature a rovněž s přihlédnutím k dílům Enquiry Concerning Human Undestanding a An Abstract of A Treatise of Human Nature a dalším titulům primární a sekundární literatury. Tematizováno je v tomto kontextu tedy nejprve Humovo pojetí percepcí jako takové (a to na základě první kapitoly Treatisu, Of ideas, their origin, composition, connexion, abstraction etc.). Poté je v souvislosti s předchozím pojednáno i o Humově pojetí identity (především objektu-tělesa) a jeho koncepce individuace, resp. i stálosti a koherence. (a to na základě čtvrté kapitoly Of scepticism with regard to senses). Na konci práce jsou kontrastovány různé možné typy objektů, jež lze (dle autora této práce) chápat jako komplexy percepcí a poté je nabídnuto schéma hypotézy o individuaci tzv. materiálních těles (bodies) v prostoru.

Web application for teaching of volume and surface area of solilds in secondary schools
Rakušanová, Lucie ; Robová, Jarmila (advisor) ; Surynková, Petra (referee)
This thesis is focused on the volume and surface area of solids, particularly on the volume and surface area of polyhedra, which are part of the high school curriculum of geometry (stereometry). The purpose of website is to provide supporting and comple- mentary material for students as well as for their teachers. The website contains several photographs, illustrations and interactive components that make it easier to understand the topics. Interactive elements include applets created in a dynamic geometry appli- cation called GeoGebra, hyperlinks, and step-by-step exercise solving. Furthermore, the thesis is supplemented by solved problems and a final summary test. 1

Intersection of solids
Otrubová, Anna ; Hromadová, Jana (advisor) ; Šarounová, Alena (referee)
The four chapters of this diploma thesis introduce a survey of the basic intersection types of solids, the focus being placed on the intersection of two pyramid and prisma solids, acting as a counterweight to most textbooks' interest in intersection of curved surfaces. The first chapter provides a detailed, wide-ranging insight into the issue of the solid and line intersection. The conclusion part of the thesis provides the reader with a brief commentary on the used literature. The work is supplemented with figures and example solutions. In the appendix part are found pre-drawn assignments. The enclosed CD contains complementary materials such as step by step solutions and 3D models created in the GeoGebra software along with drawn problems found especially in upper secondary school geometry textbooks and curriculum.
