Prediction and analysis of traffic crossings using machine learning
Hlaváček, Jakub ; Frýza, Tomáš (referee) ; Götthans, Jakub (advisor)
The thesis focuses on the area of traffic control, specifically traffic control of intersections, especially control technologies based on the obtained traffic data. The main goal of the work is the design and subsequent implementation of a real intersection Anenská and Capt. Jaroše, Pardubice in the form of a model. The work also deals with the demonstration of the used signal programs of junction control through the created model. The model is assembled from a wooden base and smaller parts are made by 3-D printing. The unit is controlled by an Arduino microcomputer. In creating this thesis, I managed to understand the comprehensive traffic management in today’s cities, which requires the current traffic situation.

A Wavelet-Based QRS-Complex Detection
Kocian, Ondřej ; Provazník, Ivo (referee) ; Kozumplík, Jiří (advisor)
This project investigates methods of construction the wavelet-based QRS-complex detector. QRS-complex detection is very important, because it helps automatically calculate heart rate and in some cases it is used for compression ECG signal. The design of QRS detector can be made with many methods, in this project were mentioned and consequently tested only a few variants. The principle of designed detector used a wavelet-based decomposition of the original ECG signal to several frequency-coded bands. These bands are consequently transformed to absolute values and with the help of the threshold value are marked positions of assumed QRS complexes. Then are these assumed positions from all bands compared between themselves. If the position is confirmed at least at one nearby band, then is this position marked as true QRS complex. To increase efficiency of designed detector, two modifications were additionally mentioned. The first one, using the envelope of the signal, had rather negative effect on detectors efficiency. The second modification, using combined signal from three pseudoorthogonal leads, had reversely very good effect on detectors efficiency. In the end, the designed detector and all its modifications were tested on signals from CSE library (exactly on leads II, V2 and V6).

Semiconductor utilization for the capture of ionizing radiation
Klus, Roman ; Varmuža, Jan (referee) ; Radil, Lukáš (advisor)
Tato bakalářská práce popisuje typy a vlastnosti nukleárních článků a analyzuje vzájemné působení ionizujícího záření a polovodičů. Polovodičové nukleární články jsou stroje, které přeměňují energii ionizujícího záření na elektřinu, detektory využívají polovodičové materiály k měření veličin. Součástí tohoto projektu je popis ionizujícího záření, polovodičů, nukleárních článků a detektorů. Následně je popsán betavoltaický nukleární článek a jeho součásti. Je realizováno měření polovodičového nukleárního článku a je proveden rozbor potvrzující pravdivost teoretických poznatků.

Automated Detection of Relations in Data Structures
Nováček, Pavel ; Fiedor, Tomáš (referee) ; Smrčka, Aleš (advisor)
This thesis deals with automated knowledge acquisition from structured data, precisely it includes detections of relations of data types in tree-structured data. The thesis is a part of Testos platform, which aims at software testing automation. The goal was to design and implement a solution that would automatically plan and execute detections over samples of real data structures. Detections would be handled by external modules called detectors that would cooperate with the solution. The final tool is a service which implements a algorithm for communicating with detectors via well-defined protocol, sending them requests in parallel to perform detections and handling results of detections. The service can be managed and tasked via created HTTP API. The results of detections, i.e. meanings and relations of input data, are used by other tools of Testos platform for the purpose of generating new test data with structure corresponding to input samples of real data.

QRS detection based on wavelet transform
Zedníček, Vlastimil ; Ronzhina, Marina (referee) ; Smital, Lukáš (advisor)
This thesis deals with implementation of detector QRS complex with use of wavelet transform. The first part is focused on formation and possibility to measure cardiac activity. The other part of thesis we will familiarise with the different possibilities of detection QRS complex and we intimately focus on wavelet transform that will be used for a project of detection QRS complex. The practical part of thesis focuses on the project of detector in programming language Matlab and his different setting. This projected detector has been tested with CSE database. Achieved results of projected detector are evaluated with the results of others authors.

System for People Detection and Localization Using Thermal Imaging Cameras
Charvát, Michal ; Kempter, Guido (referee) ; Drahanský, Martin (advisor)
V dnešním světě je neustále se zvyšující poptávka po spolehlivých automatizovaných mechanismech pro detekci a lokalizaci osob pro různé účely -- od analýzy pohybu návštěvníků v muzeích přes ovládání chytrých domovů až po hlídání nebezpečných oblastí, jimiž jsou například nástupiště vlakových stanic. Představujeme metodu detekce a lokalizace osob s pomocí nízkonákladových termálních kamer FLIR Lepton 3.5 a malých počítačů Raspberry Pi 3B+. Tento projekt, navazující na předchozí bakalářský projekt "Detekce lidí v místnosti za použití nízkonákladové termální kamery", nově podporuje modelování komplexních scén s polygonálními okraji a více termálními kamerami. V této práci představujeme vylepšenou knihovnu řízení a snímání pro kameru Lepton 3.5, novou techniku detekce lidí používající nejmodernější YOLO (You Only Look Once) detektor objektů v reálném čase, založený na hlubokých neuronových sítích, dále novou automaticky konfigurovatelnou termální jednotku, chráněnou schránkou z 3D tiskárny pro bezpečnou manipulaci, a v neposlední řadě také podrobný návod instalace detekčního systému do nového prostředí a další podpůrné nástroje a vylepšení. Výsledky nového systému demonstrujeme příkladem analýzy pohybu osob v Národním muzeu v Praze.

Subject of this Diploma thesis is the design of metal detector and luggage X-ray screening. The thesis concerns with design of frame metal detector and luggage x-ray with focus on visual appeal, keeping of functional elements and concept of construction solution. Main objective is to find solution how to connect aesthetic, ergonomic and technical aspect. Complete analysis leads to design of metal detector and luggage X-ray screening. These appliances then appeal as compact system with uniform design. Also the machines can be used separately. Design of this system of appliances is solved through ergonomic, psychologic, technical and aesthetic aspects.
