Lab tasks on compiled language vulnerabilities
Kluka, Peter Milan ; Štůsek, Martin (referee) ; Sysel, Petr (advisor)
This graduation thesis is devoted to a detailed analysis of vulnerabilities in freely distributed open-source programs. The thesis includes a description of different types of vulnerabilities that are often associated with software attacks. Static and dynamic code testing are examined in detail, as well as the tools used to detect vulnerabilities in source code. The thesis includes the development of three lab exercises, including detailed tutorials that demonstrate the consequences of incorrect implementations. The lab tasks focus on buffer overflow, path/directory traversal, and buffer over-read vulnerabilities. Every lab task includes a demonstration of the flawed code that was responsible for the vulnerability, as well as demonstration of the patched code that was used to fix the vulnerability. These tasks provide practical examples that illustrate the risks associated with inappropriate software design and implementation and demonstrate the importance of effective security techniques in software development.

Design and implementation of countermeasures against side-channel attacks on an FPGA platform
Kuřina, Petr ; Jedlička, Petr (referee) ; Dobiáš, Patrik (advisor)
Currently, significant progress is being made in the field of digital systems and cryptography, requiring adequate security against various forms of attacks. Special attention is paid to development on the FPGA (Field-Programmable Gate Array) platform, which provides flexibility and performance for implementing diverse applications, including cryptographic algorithms. This semester thesis focuses on the systematic analysis of possible leaks of sensitive information from the implementation of a cryptographic scheme on the FPGA platform. The FPGA platform is presented in the work, including HDL (Hardware Description Language) programming languages such as Verilog or VHDL. It then presents a general overview of side channels and their types, countermeasures, and a~detailed description of security techniques. The next chapter is the AES cryptographic scheme and a description of its operations. There is a chapter devoted to a comparison of current articles on the issue. The following is a description of a professional workplace, such as an oscilloscope or a Sakura-X (Sasebo-GIII) hardware board. In the final part, the measurement results are presented without any measures, only the AES algorithm is implemented, and then in the next part there is a countermeasure proposal, which is implemented and measured. The results are described and subsequently displayed in graphic form.

Word-formation patterns in contemporary French neologisms
SOUKENÍKOVÁ, Michaela
The present thesis aims to excerpt a sample of contemporary neologisms and then analyse them. The theoretical part introduces word-formation patterns used in French, which are then applied in the practical part to the excerpted sample from the Néoveille platform and further analysed with the help of a linguistic corpus, the web and artificial intelligence.

Feasibility study of a photovoltaic power plant investment project
PATERNA, Patrik
The work deals with the economic evaluation of a selected investment project for a photovoltaic power plant. The work seeks to explain the process of evaluating investment projects within technical-economic studies and methods for assessing the economic efficiency of investments. The aim is to characterize the process of evaluating investment projects and to make final financial and investment decisions for the selected investment project for a photovoltaic power plant based on calculations of economic criteria. Case studies are created in the practical part of the work, on which investment evaluation methods are applied. Sensitivity analyses are also conducted, which assess the impacts of variable changes on the final investment outcome. In conclusion, research questions are answered, and final financial and investment decisions are formulated.

Regional differences in labor productivity
FENCL, Matěj
The bachelor's thesis focuses on the analysis of regional differences in labor productivity in the selected sector - Industry, mining and quarrying divided according to the CZ - NACE classification, including the analysis of the selected plant of the company LB Minerals, s. r. o. and, on the one hand, labor productivity itself, the possibilities of measuring and defining factors that can influence both regional and corporate labor productivity. The measurement possibilities are further applied to the analysis of the Southwest region, the plant of the company LB Minerals, s. r. o. and the economic activity that prevails in the entire company. At the end of the practical part, a correct comparison and subsequent assessment of labor productivity in relation to the Southwest region is made, including the effect of labor productivity on the profitability of the company and the relationship between labor productivity and average wages.

Project Proposal of a Music Festival
Uzlová, Anna ; Spáčilová, Natálie (referee) ; Doskočil, Radek (advisor)
My bachelor's thesis focuses on the use of project management tools and methods to complete a completely new project. The first part of the bachelor's thesis describes the methods and tools used. This information is further used to analyze the current state of the company and to make proposals. The tools and methods that were chosen are further practically used in the creation of the three phases of the project's life cycle. We will include an analysis of the current state in the pre-project phase, where I will also present the marketing part of the project. The design part is included in the initiation and planning phase of the project. The final output of the bachelor's thesis is a detailed proposal, according to which it is possible to start the project within the set deadline.

This master's thesis deals with the analysis of selected waste from production and the proposal of appropriate optimization of their management in accordance with the principles of circular economy and current legislation in force in the Czech Republic. It also deals with the optimization of waste management arising in the administrative premises of the company. The aim of the work was to prepare a research of current legislative and strategic documents in the field of waste management and, in connection with this, a subsequent proposal for optimization for selected waste streams. In the experimental part, analysis of selected waste streams from the production line was carried out using FTIR, titration and vacuum evaporation methods. The first part of the thesis consists of the research of legal regulations and strategic documents in the EU and Czech republic. In the second part, the optimization of selected waste management is proposed. For some of the proposed solutions, the thesis evaluates the economic viability of the proposed solution compared to conventional management methods. The results and the methods used led to the proposal of optimization of waste management in production and administrative part of the company rPET InWaste s.r.o.
