Acoustical detection of gunshots in the open
Hrabina, Martin ; Tučková, Jana (referee) ; Sigmund, Milan (advisor)
This work is concerned with gunshot detection and recognition. Contains overview of published works and methods used in this field. Furthermore, it lists several commercial gunshot detectors. Binary gunshot detection and recognition algorithm is proposed which discriminates between gunshot and non-gunshot sounds occuring in nature. Algorithm is tested in Matlab. Proposed algorithm is implemented in TMS320C6713 digital signal processor, achieved results are compared.

Mathematical Methods in Economics
Molnárová, Dominika ; Doubravský, Karel (referee) ; Novotná, Veronika (advisor)
This Bachelor Thesis concentrates on evaluation and comparison of the situation on individual labour markets in European union using mathematical and statistical models. The thesis primarily focuses on the analysis and development of significant economical indexes, such as unemployment rate, GDP and average income. The thesis also targets on providing the relationship between the selected indexes with correlation analysis and finally sorts the mentioned EU countries into similarity ground using the cluster analysis.

The influence of deep brain stimulation on the brain connectivity
Horváthová, Ľubica ; Výtvarová, Eva (referee) ; Klimeš, Petr (advisor)
Hĺbková mozgová stimulácia (DBS) predstavuje účinnú liečbu pre pacientov s Parkinsonovou chorobou (PD) alebo farmakorezistentnou epilepsiou. Avšak mechanizmy, ktorými znižuje počet záchvatov a zlepšuje pohyb, zostávajú ešte do značnej miery neznáme. Pre lepšie pochopenie a určenie, v ktorých frekvenčných pásmach je zmena najdôležitejšia, boli urobené porovnania medzi vypnutou a zapnutou DBS pomocou korelačnej metódy a indexu fázového posunu. Jedenásť pacientov s PD a naimplantovanými neurostimulátormi z firiem Medtronic a St.Jude Medical bolo predmetom nahraných dát použitých v tejto práci. Výsledky dokazujú, že zmena konektivity počas DBS nastane a zároveň, že najviac ovplyvňuje najvyššie frekvencie ako beta, nízka gama a vysoká gama. Zmeny v týchto frekvenciách, zodpovedné za motorickú aktivitu, sústredenie a spracovanie informácií, sú v súlade s klinickou teóriou o PD. Počas tejto choroby je patologická beta aktivita hypersynchronizovaná a gama aktivita je znížená práve v motorických oblastiach. Ak sa gama aktivita počas zapnutej stimulácie zvyšuje, fyziologický stav pacientov sa čiastočne znovuobnovuje a tým zlepšuje ich hybnosť. Metódy a výsledky tejto práce budú použité pre ďalší výskum pacientov s PD a epilepsiou.

Correlation coefficients and their field of application
Rudžík, Matej ; Popela, Pavel (referee) ; Žák, Libor (advisor)
This bachelor’s thesis deals with different types of correlation coefficients and their properties depending on the data layout. The theoretical part of this work contains definitions of various types of correlation coefficients and tests related with this issue. The practical part compares the behaviour of parametric and nonparametric correlation coefficients in different situations. This comparison is realised in program MATLAB.

Acoustic Drone Detection Using Microphone Array
Múčka, Milan ; Beran, Vítězslav (referee) ; Szőke, Igor (advisor)
This work deals with methods of acoustic localization for electrical multicopters using a microphone field composed of several microphones at a certain distance. The main methods of localization and detection using sound waves are explained in the paper. Next, the algorithms that implement these methods are designed. The results summarize the results of these algorithms together with experiments to verify their functionality.

Automobilový priemysel na Slovensku ako hlavný ťahač slovenskej ekonomiky a jej vývoja
Zvarková, Zuzana ; Frömmel, Tomáš (advisor) ; Špecián, Petr (referee)
The aim of this work is to prove the mutual relationship and dependence between the Automotive industry and the Slovak economy. First half of practical part calculates cor- relation coefficients between five potential bonds of individual performance indicators (e.g. Revenues of car manufacturers and Slovak nominal GDP). Strong correlation coefficients between these bonds prove that there is a significant mutual relationship and strong dependence. Second half of practical part presents very comprehensive SWOT analysis of the automotive industry in Slovakia. The aim of the analysis is to emphasize the strong two-way relationship. Additionally, to propose, how could the automotive industry accelerate the Slovak economy if influenced properly and how it could overcome upcoming threats that could have a negative impact on the economy of the country.
