Analysis of crank and cam shaft position sensor variability
Riečica, Samuel ; Repka, Martin (referee) ; Šebela, Kamil (advisor)
This bachelor thesis deals with the working characteristics of crankshaft and camshaft position sensors used in the power unit to ensure correct injection and ignition of the fuel mixture. Their variability was determined by experimental comparison of sensor characteristics. Search of the types and designs of sensors used was carried out in the first phase. Measuring device, which represented a simplified shaft model for sensing characteristics, was designed and constructed in the next step. The experiment was conducted on a statistical sample of 100 pieces of sensors using the Hall effect. The characteristics of the sensors were recorded and evaluated using an oscilloscope with appropriate digital software. Statistical processing of the measured data was performed at the end of the thesis. The results show that the variability of the crankshaft and camshaft position sensors can have an impact on engine performance characteristics and exhaust emissions produced.

Koprivnice 3.0 - Housing A++
Lapešová, Tereza ; Moler, Vít (referee) ; Nový, Vítězslav (advisor)
The diploma thesis focuses on the design of a new district in the town of Kopřivnice. The plot is owned by the municipality. The proposal includes a multifunctional building and three residential buildings. The construction is financed through a Public-Private Partnership (PPP) between the municipality and a private investor. The thesis primarily concentrates on the residential properties with significant attention given to public spaces. The entire area of Kopřivnice is intersected by the Kopřivnička River surrounded by greenery, to which the proposed area responds. The houses are designed with a focus on maximum variability and straightforward construction.

Sport Centre Brno
Zaplatil, David ; Vostrejž, Dušan (referee) ; Odvárka, Antonín (advisor)
It is an object of sports equipment, which will be mainly used for ice hockey, as well as for the organization of other sporting and social events. The main objective in the design of architectural buildings were to meet modern requirements for the operation and use of the sports hall. Mass solution hall is designed as part of a hyperbolic curve, which rotates around a central axis. This substance is added next curve and along the perimeter. It is a sine wave, which is twice reflected on the mass of the object. This curve separates the roofing structure from the construction and glazing adds mass element dynamics, which is in my opinion the sporting character of the buildings needed. Construction is due to this curve seems to be constantly moving. This curve has another purpose and that the highest point of the curve are a total of two, is the main entrances to the building and the curve that creates a kind of "entry portal".

Deconvolution of hemodynamic response from fMRI data
Bartoň, Marek ; Kolář, Radim (referee) ; Havlíček, Martin (advisor)
This paper deals with the variability of HRF, which may have crucial impact on outcomes of fMRI neuronal activation detection in some cases. There are three methods described - averaging, regression deconvolution and biconjugate gradient method - which provide HRF shape estimation. In frame of simulations regression method, which uses B-spline curves of 4-th order for window length of 30 s, was chosen as the most robust method. Deconvolution estimates was used as HRF models for classic analyse of fMRI data, concretely visual oddball paradigm, via general linear model. Enlargement of localizated areas was observed and after expert consultation with scientific employees from neurology clinic, outcomes was evaluated as relevant. Furthermore Matlab application, which provides confortable observation of HRF variability among brain areas, was made.

Determination of Blood Pressure
Plch, Miroslav ; Smital, Lukáš (referee) ; Čmiel, Vratislav (advisor)
The thesis includes a general introduction to monitoring and measurement of blood pressure of horses, the design of algorithms for pressure curve detection and the calculation of respiratory variabilities in mechanical ventilation under anaesthesia. The first two chapters focus on anatomy, on characteristics of blood flow and on vascular system. Then it deals with the measurement of blood pressure, monitoring of a horse under anaesthesia and it describes particular thermodynamic parameters. In the following part of the thesis, the methods of pressure curve detection are described. The last part contains the description of an algorithm designed for detection of pressure curve of horses in the environment of the program LabVIEW. The program calculates, displays and saves variabilities of systolic pressure, pulse volume, pressure amplitude, pulse frequency, peripheral resistance and vascular expansion from the detected values.

Cultural Center Brno
Juračková, Lenka ; Marek, Jiří (referee) ; Šindlar, Jiljí (advisor) ; Berková, Petra (advisor)
Bachelor thesis expands an architectural study elaborated within the framework of the course AG33 to the stage Documentation for permission of construction and Documentation for building permission. The topic of the thesis is a Culture Center in Brno, for which was selected a lot on the street Údolní in front of square Obilný trh in a slope under the Špilberk. Close to the lot is located University hospital Brno – maternity hospital and the building of Public Guard of Rights and historical build-up area from 19. century, which strictly keeps a street line, this street line was disrupted by gap site during the 2. World War, due to the bomb fallout. New building of the cultural center is designed in this gap site between two historical houses and completes original frontageline. The main idea of design was to keep the fromtage line and at the same time interconnect by designed project an opposite square with a park and castle Špilberk. Object comprises three parts. The main object is in the shape of a letter L and its back part is partly built in the slope, in bigger wing of the building is located a foyer, a big concert hall, performers, staff and technical facilities and storage area in the first floor, small conference hall with foyer in the second floor and gallery in the third floor, in smaller wing café and gym are located. Second part includes sheltered penthouse in the shape of letter L which is designed in form of steel structure, which is adjacent to the main object and thus creates square-shaped yard. The cover at the same time creates sheltered passage from Obilný trh onwards to Špilberk. Third object is the smallest one, it has cuboid shape and it is defined as a commercial space especially for free-time activities.

Time progression of metrological characteristics of electromagnetic current meters
Březina, Jiří ; Brázda, Martin (referee) ; Žoužela, Michal (advisor)
This experimental diploma thesis investigates the changes in the metrological characteristics of the electromagnetic current meter of velocity. The theoretical part of the thesis includes a brief summary of technical and metrological characteristics of these types of devices. In addition, it describes the tested device, the test track, and the measurement procedure, which consists of two variants: long-term monitoring with a relatively regular monthly measurement interval and short-term monitoring with a regular daily measurement interval. The evaluation of the experimental work focuses on the repeatability and variability of the displayed point speed values and their stability over time. Furthermore, the parameters reported by the meter during long-term and short-term monitoring are compared to each other. The results are also compared with similar experiments.
