Expert evidence
Šváb, Martin ; Richter, Martin (advisor) ; Bohuslav, Lukáš (referee)
Expert evidence Abstract This thesis deals with the use of expert opinion as evidence in criminal proceedings, the conditions for its admissibility and possible defects of such expert opinions. Expert opinions play a significant role in criminal proceedings and are often irreplaceable evidence in the process of proof. Despite their irreplaceability, however, they do not carry any greater weight or probative force among other evidence and must therefore, like other evidence, be assessed in accordance with the principle of the free evaluation of evidence. The thesis deals with the basic institutes of the law of evidence, expert activities, the status and conditions of activities of individual subjects of expert activities and expert opinions, the process of their preparation and their taking. It describes the process of preparation and the individual parts of an expert opinion according to the new legal regulation implemented by Act No. 254/2019 Coll., on Experts, Expert Offices and Expert Institutes (Act on Experts) and the related implementing decrees. The thesis describes the basic requirements that an expert opinion must meet in order to be admissible evidence in criminal proceedings, and at the same time describes what defects in expert opinions are recognized by theory and practice using case law...

Šváb, Martin
The topic of my bachelor thesis is Durable pastry with the addition of animal fats. The first part of the thesis is the characteristic of durable pastry and the classification of product Škvarkové bonbony into biscuits. The thesis then describes raw materials for the biscuit production, focusing on the raw materials needed for Škvarkové bonbony, animal fats and various spices. The thesis also covers the history, characteristics of the biscuits and the manufacturing process. It points out microbiological, physical and chemical hazards such as acrylamide and uneven moisture in the biscuits after baking. In conclusion, the thesis presents the recipe of Škvarkové bonbony and the manufacturing process.

Změny senzorických vlastností lihovin vlivem vnějších faktorů
Šváb, Martin
The theme on this diploma thesis is „Changes in sensory properties of spirits due to external factors“. In the theoretical part are contained chapters on the alcohol, production of alcohol and spirits. In the practical part, an experiment was established in 2017 in which the selected spirit drink was stored in two types of bottles under different storage conditions. The spirit drink used in the experiment was the domestic rum. The diploma thesis is focused on spectrophotoscopic measurement of samples of domestic rum, for which the intensity of color changes was monitored. In addition, a sensory evaluation of the colour intensity of the samples was carried out. The measurements were carried out for one year at regular intervals. The results is obtained were statistically and graphically evaluated. The results indicates that L*(D65) a*(D65) b*(D65) varied significantly over time under different storage conditions For samples stored at 6 °C, the L*(D65) gradients increased more slowly and valeus a*(D65) and b*(D65) were decreased slowier than those stored at 20 °C. The samples that were exposed to different light modes at 20 °C also increased value L*(D65) and decrease a*(D65) and b*(D65) values. The fastest changes to these values were in samples stored under a fluorescent lamp, then under daylight, and the slowest changes were in samples that were stored in the dark. By measuring, it was found that the bottle type had a demonstrable effect on the storage of samples exposed to different light modes. In all types of the samples, the total color differentiation ΔE* ab was calculated, indicating whether the difference in color was already visible for the human senses. This was confirmed by sensory analysis.

Malware analysis and reverse engineering
Šváb, Martin ; Čermák, Igor (advisor) ; Hlaváč, Jindřich (referee)
Focus of this thesis is reverse engineering in information technology closely linked with the malware analysis. It explains fundamentals of IA-32 processors architecture and basics of operating system Microsoft Windows. Main part of this thesis is dedicated to the malware analysis, including description of creating a tool for simplification of static part of the analysis. In Conclusion various approaches to the malware analysis, which were described in previous part of the thesis, are practically demonstrated on unknown malware sample.
