Speed Measuring of Vehicles Using Radar
Vlkovič, Vladimír ; Široký, Adam (referee) ; Maršík, Lukáš (advisor)
This masters thesis is focused around the designing and implementation of an anpplication that can extract information on speed of vehicles from radar data. The radar measurements were done by using a continous wave radar. The emphasis is placed on the computation of the angle in which the car approaches the radar and on the speed correction based on this angle. The final design was implemented in Matlab. The evaluation of the implemented solution was done on reference data.

Radar Signal Processing for Radio Altimeter
Krasňanský, Milan ; Maršík, Lukáš (referee) ; Zemčík, Pavel (advisor)
Táto diplomová práca sa zaoberá návrhom a implementáciou algoritmu pre spracovaniu signálu z radaru využívajúceho frekvenčne modulovanú kontinuálnu vlnu. Cieľom je implementácia algoritmu, ktorý by bol dostatočne rýchly (výpočet v reálnom čase na cieľovej platforme) a dostatočne presný pre použitie v rádiovýškomere v ľahkom lietadle so zameraním na použitie počas pristávacieho manévru. Hlavnou metódou spracovania signálu, použitou v implementácii, je Diskrétna Fourierova transformácia. Vytvorený algoritmus bol otestovaný na reálnych letových dátach a pre pristávací manéver dosiahol uspokojivé výsledky.

Sleep scoring using artificial neural networks
Vašíčková, Zuzana ; Mézl, Martin (referee) ; Králík, Martin (advisor)
Hlavným cieľom semestrálnej práce je vytvorenie umelej neurónovej siete, ktorá bude schopná roztriediť spánok do spánkových epoch. Na začiatku je uvedené zhrnutie informácií o spánku a spánkových epochách. V ďalších kapitolách sa nachádza dôkladnejší prehľad metod na spracovávanie signálov a na klasifikáciu. Po zhrnutí teoretických znalostí potrebných na uskutočnenie praktickej časti práce boli na základe tohto rozboru vypočítané zo signálov potrebné znaky. Tieto znaky boli podrobené štatistickej analýze a na jej základe boli vybrané niektoré znaky, ktoré boli vhodné ako vstup do neurónovej siete, ktorá je po naučení schopná triediť spánkové epochy do príslušných fáz.

Speed Measuring of Vehicles Using Radar
Novák, Adrián ; Široký, Adam (referee) ; Maršík, Lukáš (advisor)
This thesis focuses on the process of creating a desktop application that processes radar data, from which it detects vehicles, their speed, and direction in an appropriate manner.The core of the application uses a Fourier transformation to transform radar data from time to a frequency domain. This frequency spectrum is used to get the important informationfor the calculation of vehicle speed, followed by a correction of the calculation by the cosine factor. The result of this thesis is a desktop application, which allows its user to obtain information from radar data about the detected vehicle and subsequently, to determine its speed.

Driver State Monitoring
Blašková, Barbora ; Prustoměrský, Milan (referee) ; Chudý, Peter (advisor)
Vedieť šoférovať auto je v dnešnom svete považované za dôležité, či dokonca nutné. Avšak, s pribúdajúcou premávkou je nevyhnutné, že sa stanú nehody, ktoré môžu mať aj fatálne následky. Množstvo informácií, ktoré musí vodič vedieť spracovať sa neustále zvyšuje a s tým aj stresové situácie, počas ktorých vodič nemusí vedieť racionálne uvažovať. Táto práca sa zameriava na nájdenie techník a postupov ako implementovať monitor, ktorý by predikoval level stresu vodiča počas jazdy, aby sa predišlo takýmto nehodám.V práci boli implementované dva typy modelov - osobný a všeobecný. Oba využívali fyziologické dáta spolu s kinematickými, ktoré boli nahrané počas jazdy. Oba modely boli schopé predpovedať úroveň stresu s vysokou pravdepodobnosťou.

Radar Detection of Vital Signs
Köteleš, Dávid ; Zemčík, Pavel (referee) ; Maršík, Lukáš (advisor)
Nowadays, it is very important to measure the vital signs of a person. Thanks to the data that we get from measure, we can control health of the person. It is usefull as well in sports, where we can control performance of sportsman. Different technologies are used for measurement. We can divide these technologies in contact and contactless methods. Contact methods have their disadvantage and that one is when patient can not feel comfortable and then the results may not be correct. Thats why we are currently using contactless methods that we try to develop to achiev highest possible accuracy. In this work are signal processing strategies using fast fourier transform and different filtration techniques for monitoring vital signs described using radar device and eventually their variatons. These strategies are then tested on real data and compared to achiev best result. The IWR1642Boost and Texas Instruments demo software is used for practical exploration.

Lowcost proximity sensor for mobile robot based on SRF05 sensor
Majerčík, Pavel ; Najman, Jan (referee) ; Krejsa, Jiří (advisor)
This master's thesis deals with determination of properties of the ultrasonic sensor SRF05. It is about finding factors that distort or have other negative effects in any way on the proper functionality of these sensors. First of all, it was necessary to program a chip mounted on signal processing board for correct functionality and operation of sensors. Then a few sets of measurements were done to determine the behaviour of sensors for different distances. In addition, we had to carry out many more measurements to find out the influence of temperature, light conditions, material of the sensed surface or cross-noise caused by the use of multiple sensors. In the next step, the approximate shape of the transmitted ultrasound was investigated to determine the zone of detection. The last task of this thesis was to compare the SRF05 sensors with other ultrasonic sensors from different manufacturers.
