Impact of technological parameters on electrochemical properties of negative electrode in lithium-ion battery
Živčic, Samuel ; Máca, Josef (referee) ; Libich, Jiří (advisor)
This bachelor thesis deals with the issue of li-ion batteries and consists of two main parts. The first part of the thesis deals with a theory. It describes the functionality of electrochemical cells, especially li-ion cells. Operational principle of the cell is discussed, with the main focus given on negative electrode (anode) and the material it consists of, the natural graphite, mainly his electrochemical properties. Last chapter of theory describes expected impact of technological parameters on electrochemical properties of negative electrode. The second part of the thesis is the practical part. First, it describes procedure of making electrodes in laboratory and afterwards it provides an explanation of used measuring methods, steps taken during the measurement, and the results of the measurements. At the end of the thesis, the influence of pressure and layer thickness on electrochemical properties of natural graphite and on capacitive and current characteristics of negative electrode is evaluated.

Editing roundabout Hviezdoslavova x Bedrichovicka
Klusková, Jana ; Pančík, Vladimír (referee) ; Smělý, Martin (advisor)
The aim of this Bachelor's thesis is solution of the problem of the roundabout that connects road II/430 Hviezdoslavova and the road III/715283 Bedřichovická in city district Brno Slatina. It is about single lane roundabout. The crossroad is situated on the edge of the city and the main problem is satisfactory capacity of it. This problem is linked to the movement of the vehicles leaving the city in the afternoon hours and arriving the city in the morning hours and also with transit transport across the roundabout. The aim is to design new geometry of the roundabout to increase its capacity and also increase the fluidity and efficiency of the passage of vehicles through the intersection with emphasis on the safety of vehicles and pedestrians . The work also includes solutions for pedestrians through the intersection and the draft modifications sidewalks, barrier adaptations of pedestrian crosswalks , points for crossing and adjust the bus stops.

Exploring the influence of pressure on the life of lead acid batteries for hybrid electric vehicles
Pospíchal, Martin ; Tošer, Pavel (referee) ; Bača, Petr (advisor)
The lead-acid batteries used in hybrid electronic vehicles HEV operate in high-rate mode in a state of partial charge PSoC. It occurs when the degradation mechanisms related to irreversible sulphation and negative electrodes are a limiting factor in the life of lead-acid batteries. The electrode system was applied to experimental pressure cells of different sizes. Exp. cells were subjected to measurement and evaluation of potential negative electrode, a negative active mass resistance, contact resistance of transition collector - the active mass with the evaluation and measurement of pressure fluctuations within four PSoC runs.

River regulation and designing flood protection
Úlehla, Jiří ; Špano, Miroslav (referee) ; Duchan, David (advisor)
This thesis focuses on assessing the capacity of the river channel Becvy in the urban area of Prerov and design of flood protection for the city. Flood protection was designed in two variants. In the first variant dealt with recess bottom of the river. The second variant included a proposal of flood protection wall combined with a mobile barriers. The results are summarized in the synoptic maps.

Digital Image Steganography
Mazánek, Antonín ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This bachelor's thesis introduces the steganography scientific discipline. It presents its ancient and relative recent history, mentions its current use and outlines the possible directions for steganography future. It introduces steganography into context of hiding information superior domain and highlights differences between other methods in this domain. It describes steganography subdivisions and closer deals with digital image steganography. It presents some known methods and types of digital image data. The thesis also contains more detailed description of image data in PNG format. It describes the implementation of LSB and PVD steganography methods with images in PNG format as cover object and evaluates their key properties, namely: imperceptibility, capacity and robustness. At the end of the thesis, the author's reflection on the results and possibilities of further modifications of the mentioned methods is given.

Reconstruction of a beam bridge
Otevřel, Rostislav ; Klusáček,, Ladislav (referee) ; Nečas, Radim (advisor)
The work deals with the calculation of current carrying capacity of the bridge girder structure according to ČSN 73 6222 and the proposal for a new bridge. The bridge is used to transfer local roads across the river Svratka. The bridge is designed as a plate full cross-section, simply placed with a length of 13,174 m. The communication category is S 7.5. Loads and assessment are done according to Eurocode.

CDMA Network Capacity
Pasečný, Jan ; Kejík, Petr (referee) ; Hanus, Stanislav (advisor)
The Bachelor thesis deals with determining which factors influence the capacity of CDMA network. This type of network is now being used worldwide due to its huge increase in capacity when compared to other transmissions systems. The work contains summary of basic parameters of single-cell and multi-cell systems with reference to the capacity. Obtained results are assesed and compared at the end of the work.
