Thrombi detection in main brain arteries in CT image data
Líška, Martin ; Nemček, Jakub (referee) ; Chmelík, Jiří (advisor)
The master’s thesis deals with automatic preprocessing, segmentation and consecutive analysis of volume data of anonymized patient CTA acquisitions with an indication of stroke. Preprocessing of volume data is an essential step for proper vascular tree segmentation and analysis. The region growing method was used to segment the vascular tree of the brain. After extracting the vascular tree, the labeling of individual branches was applied in the algorithm and the appropriate features were extracted. The analysis examined the features of vessel lengths, their diameter and local brightness profiles, which are important indicators of possible stenosis or occlusion of the main vessels of the brain. The output of the algorithm are various modalities of diagnostic, assisted visualizations of the segmented vascular tree. The segmentation and analysis algorithm of cerebrovascular system was created in the MATLAB programming environment.

Design of an Information System Part
Liška, Michal ; Pivovar,, Jiří (referee) ; Neuwirth, Bernard (advisor)
The bachelor thesis focuses on solving the issue regarding enhancing the administration workflow effectiveness at the local election of the representatives. It goes the way of designing a part of the information system – the election application, created in the environment of the MS ACCESS 2013. The thesis is based on the database and information system theories and their use in a production environment. I have used the law normatives of the Czech republic for the organization and election processing based on the specific type of the local authority.

Information System Assessment and Proposal of ICT Modification
Líška, Michal ; Novák, Lukáš (referee) ; Koch, Miloš (advisor)
The bachelor thesis analyses the current state of use of the information system in the described company and suggests optimal solutions for its effectiveness based on the findings. The major part of the proposed changes is devoted to the issue of data updates in the information system. The proposed solution should lead to eliminating the risks associated with problematic uploads, updated data and overall efficiency in the company's information system.

Audio Amplifier with Network Streaming and Sound Equalization
Liska, Matej ; Zeman, Kryštof (referee) ; Štůsek, Martin (advisor)
Diploma thesis contains the theory for the design and realization of a prototype audio amplifier device with the possibilities of digital or analog input content. It approach the features of D/A converter, analog filtering, volume control and amplification. Besides others, it describes the regulation of supply power voltages for individual active parts of device and approaches the software audio platform for acquisition and processing of audio data, including equalization. The thesis contains an general schematic design, created placement of individual components on board, including their table of descriptions and evaluation of the achieved results, including measured values and graphs.

Experimental stand for rotational heat pipe verification
Liška, Martin ; Sikora, Michal (referee) ; Vlach, Radek (advisor)
This bachelor thesis presents a design of an experimental stand for testing of cooling effects on electrical machines trough rotational heat pipe and mainly with design and construction of experimental stand, that represents rotational heat pipe of real machine rotor. Pipe is heated by means of resistance conductor winding and average temperature on a pipe surface is scanned with a additional parallel winding. Experimental stand was designed for subsequent experiments and for evaluating of rotational heat pipe parameters.

Sales Promotion and Advertising of Company
Liška, Marek ; Bednářová, Markéta (referee) ; Mráček, Pavel (advisor)
The main goal of my work is based on the analysis to propose appropriate changes / additions to marketing communication tools of a particular company, focusing mainly on sales promotion tools and advertising. The implementation of the proposals should then increase the awareness of the company, gain new customers or increase the satisfaction (and thus re-visit) of existing customers. I also want to focus on the start-up and subsequent operation of the company in connection with the pandemic situation and the resulting crisis. The first theoretical part is focused on defining individual economic concepts, methods and tools of communication. The second practical part is mainly based on the method of analysis of the current state of the company and the competition. In this part, I also focus mainly on the communication tools used by the salon, on the target group of customers, and the overall evaluation.

Intergration of a charging station into a family house photovoltaic system
Liška, Martin ; Langerová, Petra (referee) ; Šedrlová, Magdalena (advisor)
This bachelor’s thesis deals with integrating a charging station into a family house photovoltaic system. The thesis is divided into two parts, the theoretical and the practical. The purpose of the theoretical part was to conduct research about current possibilities concerning charging stations and their integration into the household. In the practical part, there were created function designs to integrate the charging station into the intelligent household and there was realised the testing of the selected charging station.

Finding Weak Spots and Risk Analysis of a Part of the Information System in a City
Liška, Michal ; Novák, Lukáš (referee) ; Koch, Miloš (advisor)
The diploma thesis deals with the problem of finding weak points and risk analysis of a part of the information system at the municipal office of the Brno-Líšeň district, which deals with the issue of the organization of elections, namely the administrative provision and the constitution of the district electoral commissions. The thesis is based on the theoretical apparatus in the field of information systems, database systems and risk engineering. The thesis used the analysis of the Czech legal norms for the organization and conduct of elections and the specific conditions of the chosen type of municipal office.
