Connectivity / Democratic City_Radnice pro Staré Brno
Beran, Jan ; Rozsypal, Petr (referee) ; Palaščak, Michal (advisor)
The bachelor's thesis deals with the design of the town hall on Mendl square. The space is currently chaotic in places with intensive traffic, which needs to be calmed down and restored to a representative form and function. The proposal therefore works with the specified plot in the situation of a winning study for the new Mendlovo náměstí. The proposed building is multifunctional, with civic amenities and housing.

Docking Station for Automatic Charging of Batteries of Robot
Beran, Jan ; Janoušek, Vladimír (referee) ; Rozman, Jaroslav (advisor)
The aim of this thesis is to create a functional docking and charging system for the Trilobot robot, which is improved and modified for use in future projects as a part of this thesis. The theoretical part discusses the path planning methods, battery types and charging methods, types of docking stations and the charging method itself. Also, a robot refurbishment design is presented, which is then implemented, along with the docking station. The refurbished robot has functional control software in the ROS framework, which allows it to perform not only the task of autonomous battery charging. In this thesis, a test of the whole system is also performed and the results are evaluated.

Structural study of metal-CeO2/Cu(111) model systems by RHEED
Beran, Jan ; Mašek, Karel (advisor) ; Jiříček, Petr (referee)
The cerium oxide was deposited by reactive vacuum evaporation on the (111) surface of copper single-crystal in oxygen atmosphere at constant substrate temperatures of 25řC, 300řC and 450řC and at increasing temperature from 25řC to 450řC. In each case, the cerium oxide grew epitaxially with the (111) plane parallel to the substrate. The lattice parameter of the oxide increased up to the value of 5,28 during the deposition. At increasing temperature the growth of additional three-dimensional domains with tetrafold symmetry and (100) plane parallel to the surface was observed. Lattice parameter of these domains exhibited the value of 5,36 in the direction parallel to the surface. These domains were also observed by STM. The palladium grew on the cerium oxide surface in form of epitaxial islands having (111) epitaxial plane parallel to the substrate surface. The palladium deposition resulted in the partial reduction of the oxide layer. The reduction was caused by the interaction of the palladium and oxygen atoms leading to the formation of PdO phase. This feature became more pronounced during annealing at 300řC. Annealing at higher temperatures led to coalescence of the palladium islands and thermal induced decomposition of the palladium oxide.

Study of the structural properties of model ceria based catalysts
Beran, Jan
This work is concerning the study of model ceria based calalysts structure by methods of electron diffraction RHEED and photoelectron spectroscopy XPS. The influence of deposition conditions and substrate on the growth of epitaxial cerium oxide films on copper single crystals is described in detail. The work then describes the interaction of cerium and tin in model systems and the creation of SnCeOx mixed oxide and its structure. In the last chapter, the interaction of palladium with cerium and tin oxide layers is examined, and the creation of paladium bimetallic alloys is described. Powered by TCPDF (www.tcpdf.org)

Educational Tutorial for Using of Arduino in Robotics
Beran, Jan ; Veigend, Petr (referee) ; Rozman, Jaroslav (advisor)
The aim of this thesis is to create an educational tutorial for using Arduino in robotics with the Trilobot robot. The tutorial aims to be focused on the target group of elementary school students and above with an interest in robotics and MCUs, but without any advanced knowledge of their operation. The theoretical part will summarize the current tutorials available for the Arduino and similar, together with the design of the reconstruction of the Trilobot robot and the design of the tutorial. In the practical part, both the creation of the robot itself and the preparation of slides in both Czech and English languages and source codes for the tutorial and testing will be implemented.

Patency of dialysis fistulas in patients undergoing vascular interventional procedures.
Kaván, Jan ; Lambert, Lukáš (advisor) ; Chochola, Miroslav (referee) ; Beran, Jan (referee)
Purpose. The primary objective was to compare primary and secondary patency, number of percutaneous transluminal angioplasty (PTA) interventions and cost-effectiveness among PTA, deployment of a stent, or a stent graft in the treatment of failing arteriovenous dialysis grafts. The secondary objective was to compare the residual diameter at the site of dialysis shunt stenosis using sonography and digital subtraction angiography (DSA). Methods. Sixty patients were randomly assigned to either PTA, placement of a stent or stent graft. Follow-up angiography was scheduled at 3, 6, and 12 months or when requested by the physician. Residual diameter of a dialysis shunt stenosis was measured in 20 patients with significant stenosis by ultrasonography and on an angiogram from DSA. Results. During a median follow-up of 22.4 months patients with PTA, stent, or stent graft required 3.1±1.7, 2.5±1.7, or 1.7±2.1 (P=0.031) secondary PTA interventions. The primary patency rates were 0%, 18%, and 65% at 12 months and 0%, 18%, and 37% at 24 months in the PTA, stent, and stent graft group respectively (P<0.0001). The cost of the procedures was €7,900±€3,300 in PTA group, €8,500±€4,500 in stent group, and €7,500±€6,200 in stent graft group (P=0.45). The mean residual diameter measured by ultrasonography and DSA was...
