Text Dependent Speaker Verification
Fux, Jan ; Glembek, Ondřej (referee) ; Matějka, Pavel (advisor)
The goal of this Bachelor's thesis was to design text dependent speaker recognition system. There were few systems tested for MIT database. This database contains recordings of 0.46s average length. Best case for recognition is to use a combination of DTW system using posterior probability estimation (posteriograms) as an output of Phoneme recognizer and acoustic SID system based on iVectors and PLDA (Probabilistic Linear Component Analysis). Fusion with Neural network gives the best results (EER). These are 17.84% EER for women and 16.38% for men. It's 49.9% relative improvement for women and 54.2% for men against acoustic recognition alone.

Biometric system for retina and iris recognition
Hájek, Josef ; Derawi, Mohammad (referee) ; Provazník, Ivo (referee) ; Drahanský, Martin (advisor)
Tato disertační práce se zabývá biometrickým a medicínským zařízením pro simultánní snímání duhovky a sítnice oka v jednom kroku. V případě biometrického zaměření je práce rozšířena o vzájemnou fúzi těchto dvou biometrik do jedné šablony, kdy multimodální systém vykazuje mnohem lepší parametry než systém unimodální, a to především ve větší unikátnosti, univerzálnosti a velmi obtížně proveditelnému útoku (až téměř nemožnému) na senzor. V případě medicínského využití práce dále rozvíjí detekci a klasifikaci nemocí pro základ expertního systému pro oftalmologické účely, který bude umožňovat pomoc lékaři při stanovení diagnózy nálezu v obrazu sítnice (či duhovky) oka.

Assessing the Synergistic Effects of the Selected Consolidated Entity
Hájková, Jana ; Kubovic, Pavel (referee) ; Rajchlová, Jaroslava (advisor)
This diploma thesis is aimed at assessing the existence of synergistic effects of the selected consolidated entities in the Czech Republic. Using specific financial metrics, the objective of this thesis is to identify the synergistic effects which occur among five consolidated entities operating in the area of property. Measurement and evaluation are performed pursuant to analysis of financial statements as well as qualitative data and are supposed to lead to assessing the existence of synergy in given sphere of national economy.

Breathing Rate Estimation from the ECG and PPG Signals
Blaude, Ondřej ; Němcová, Andrea (referee) ; Kozumplík, Jiří (advisor)
This bachelor’s thesis is focused on breath rate estimation. In this thesis, methods of breath rate estimation from the ECG and PPG signal are described and implemented. In the first two chapters the basics of ECG measurements are described, as well as the measurements of the respiratory system activity and the PPG signal. The third chapter then describes the ECG/PPG-derived respiratory signal estimation methods, later on the breath rate determination. In the fourth chapter, chosen methods are implemented and the created algorithms are applied on real data from the BIDMC database.

Changes in Consolidated Financial Statements as a Result of Changes in the Size of the Share in the Company
Křenková, Vendula ; Škodová, Eva (referee) ; Rajchlová, Jaroslava (advisor)
The diploma thesis is focused on the issue of consolidated financial statements, namely the change of the consolidation method, the consolidation group Energie - stavební a báňská. The theoretical part defines the basic concepts and ways of calculations related to the topic. In the analytical part, the thesis deals first with the analysis of the current economic situation of the group, as well as with the calculation of the full consolidation method. This area will proceed freely to the design part, which includes a concrete proposal for streamlining the economic results of the consolidation group. Finally, the effects of the proposed change in the consolidation method will be fully evaluated using financial analysis.

Assessing the Synergistic Effects of the Selected Consolidated Entity
Nováčková, Veronika ; Ing, Kubovic Pavel, (referee) ; Rajchlová, Jaroslava (advisor)
The thesis focuses on the methods of assessment of synergy effects in a consolidated entity. The text includes a assessment of economic situation of the consolidated unit and analyzes a draft set of economic indicators suitable for assessing of synergy effect. Synergy effect is monitored in several selected areas through a comparison between the consolidated unit and the mother company. Results of the analysis of the draft indicators are assessed to determine whether synergies were achieved after the acquisition.
