Modern detection methods of energetic materials
Šesták, Jozef ; Bednařík, Karel (referee) ; Friedl, Zdeněk (advisor)
The review of modern detection methods of explosives was composed. Firstly the thesis deals with the detection methods commonly used in forensics science such as gas chromatography, mass spectrometry, ion mobility spectrometry, Raman spectroscopy and mainly their innovations. Then the thesis is focused on simple but very sensitive methods using fluorescence and chemiluminescence. At the end a methods as the results of a latest research are mentioned. The main of them are micro cantilever sensors and differential reflectometry. Security and counterterrorist warfare is main point of thesis.

Detection methods of energetic materials
Procházka, Michal ; Diviš, Pavel (referee) ; Friedl, Zdeněk (advisor)
A research on current methods of detection of explosives and related materials was made. At first the thesis studies methods of detection and analysis of explosives including chromatographic methods (TLC, GC, HPLC, IC), mass spectrometry and its variations, ion mobility spectrometry and infra-red spectroscopy. Next the attention is placed on detection of explosives in solid phase by X-ray detection, nuclear magnetic and quadrupole resonance and thermal neutron activation. Practical applications of these methods are of great importance in this thesis as well as their usage in the counterterrorist fight.

Detekcia a korekcia typografických jevov v značkovanom texte
Makeš, Dominik
In this thesis, I am dealing with an design and implementation of finite deterministic automaton. Its role is to process the ConTeXt input file and make a decision about its typography correctness. In next step, it will offer the recommendation how to correct the mistake and will be able to make simple automatic correction. Thesis is also including the comparision with existing programs and the tests on real documents. Thesis is also including theoretical subscription of formal languages and finite automaton.

Metanol v lihovinách a možnosti jeho detekce
Němec, Michal
The Bachelor thesis "The methanol in spirits and possibilities its detection" describes the basis alcohols, their occurence and properties. The detailed description of methanol, its chemical and physical properties, use, manufacture and physiological effects are described. The work was also focused on ethanol, its production, properties, metabolism and its wide range of applications. The work refers to a danger of methanol and ethanol and what they can cause when they are eaten. Part of Bachelor thesis is devoted to the possibilities of methanol detection, where the methods of methanol detection in spirits with a focus on the determination of methanol by gas and liquid chromatography are described and the description of the lesser known methods as well. The work also describes the methods, which are used for detection of the presence of methanol in spirits that exist on the Internet and where their functionality is not proven and these are dangerous due to the possibility of subsequent methanol poisoning. Conclusion of the literary part is dedicated to the legislation about spirit drinks. The new law about mandatory labeling of spirits, which arose in connection with the methanol affair is mentioned as well. The practical part was focused on the applicability of the method for methanol detection in spirits, which is described in the literature. It has ben proven that the certified method is not suitable to detect the presence of methanol in spirits.

Využití NIR spektroskopie při kontrole falšování kozí syrovátky
Novotná, Petra
The diploma thesis dealt with the theme "The use of NIR spectroscopy in the control of goat whey adulteration". The aim of this thesis was to verify the potential of NIR spectroscopy to check of devaluation goat whey with cow whey. In the theoretical part was briefly described the problems of food adulteration, some of the methods used in the control of food with focusing on the near-infrared spectroscopy technique and its application in the dairy industry. Further was described whey and its composition focusing on goat whey, whey processing and the possibilities of using whey in food industry. In the practical part were measured goat and cow whey and their binary mixtures at various concentrations. For the qualitative evaluated of NIR spectra was used discriminant analysis. The results showed that near-infrared spectroscopy that near-infrared spectroscopy is suitable for the authentication of goat whey.

Pojistné podvody na motorových vozidlech
Kolísek, Jiří
The thesis deals with the issue of insurance fraud on motor vehicle insurance. Insurance fraud is a serious problem affecting not only insurers, but also the whole society. Insurance fraud is being committed in connection with insurance and participants are both natural and legal persons in order to elicit insurance. Insurers respond to new trends in insurance fraud specialist staff training, creation of specialized teams, investment in new technologies and finding new sources of information for the prevention, detection and disclosure of insurance fraud. In my work to illustrate some cases of insurance fraud, also the tools and options as insurance fraud to detect, prove and make arrangements for the future.

Inhibiční látky v mléce a způsoby jejich detekce
Mrázková, Martina
The bachelor work deals with occurrence of inhibitory substatnces in milk and thein detection. They pose a gray concern since they cause problems during the milk processing procedures as well as they may reprepresent possible health risk. There are described individual groups of the inhibitory substances in the milk in this thesis, identified possible sources of contamination and their possible effect. Further on there are discussed possible sources of contamination, including usage of medication, maximal residual limits and prevention of milk contamination in general. Last part deals with detection methods of the inhibitory substances categorized in variol ways.
