Methods of deep learning in image processing tasks
Polášková, Lenka ; Marcoň, Petr (referee) ; Mikulka, Jan (advisor)
The clue of learning to recognize objects using neural network lies in imitation of animal neural network's behavior. In spite the details of how brain works is not known yet, the teams consisting of scientists from various medical or technical professions are trying to search for them. Thanks to giants like Geoffrey Hinton science made a big progress in this domain. The convolutional networks which are based on animal model of optical system can be advantageously used for image segmentation and therefore they ware chosen for segmentation of tumor and edema from images of magnetic resonance. The models of artificial neural networks used in this work had achieved the 41\% of success in edema segmentation and 79\% in segmentation of tumor from brain issue.

Virtual measuring instruments to support the education
Bilík, Petr ; Marcoň, Petr (referee) ; Mikulka, Jan (advisor)
This diploma thesis deals with the creation of the Virtual Measuring Instruments web application. This tool mainly enables us to simulate the real measuring instruments widely used in the laboratories of FEEC BUT. It is intended to serve students for initial acquaintance with specific devices. The theoretical part is focused on the research into the web applications programming and suitable programming languages to implement the proposed application are selected. Furthermore, the specific virtualized devices are described. The result of the experimental part consists in creating a universal application interface to extend the proposed application with other devices. Finally, the specific tests of the developed platform are presented.

Smart Cities
Soldán, Michal ; Sedláček, Pavel (referee) ; Marcoň, Petr (advisor)
Tato bakalářská práce se zabývá obecným úvodem do dílčích projektů, které jsou důležité pro realizaci chytrých měst i v nich používaných technologií. Podrobněji tato práce přibližuje projekty v různých zemích, hlavně však v Japonsku a na Havaji. Konkrétně shrnuje technologicky pokročilé energetické řešení a testovací projekty chytré sítě, které jsou základním kamenem pro budoucí chytrá města i efektivní využití elektomobilů. Práce také zmiňuje projekty chytrých měst v Evropě, kde je synchronizace vyvinutých technologií testována v praxi.

IoT Control Module
Haman, Martin ; Marcoň, Petr (referee) ; Szabó, Zoltán (advisor)
This bachelor thesis deals with the research of the possibilities of wireless data transmission from the controllers IoT modules and their construction. At first there is compared wireless technologies, network protocols, their suitability depending on the application of the IoT control module. Then it is designed the IoT control module using a Wi-Fi module (based on Espressif ESP8266 integrated circuit) communicating over a MQTT network protocol. Thesis continue with selection, compilation of the firmware, creation of script for control heating system, descriptions of methods for controlling the IoT control module and display of measured data. The possibilities of creating a MQTT broker and security of data transmission are described below. In conclusion is documented and verified its functionality.

Spectral computed tomography: comparison of real and virtual nativ images
Širůčková, Kateřina ; Bartušek, Karel (referee) ; Marcoň, Petr (advisor)
Advanced X-ray medical diagnostic methods massively increase the radiation exposure of patients. Therefore, it is necessary to focus on the reduction of radiation and its stochastic and deterministic effects. This project compares real native images TNC with virtual native images VNC. Virtual native images are acquired by spectral computed tomography method and it is suggested that VNC could potentially substitute real native images, thereby, the total radiation dose from multiphase spectral CT would decrease. A comparison was performed by defining certain parameters that represented the differentiation of the measured and calculated values in the images. The parameters were SNR, CNR, absolute difference, relative error and they were analysed by statistical tests using p-value and correlation analysis. Another output is a database of patients with compared parameters from real and virtual native images.

General use of EEG sensors for mind controlled devices
Blažej, Svätopluk ; Sekora, Jiří (referee) ; Marcoň, Petr (advisor)
This bachelor thesis deals with various types of sensors for collection of EEG data and their application in mind-controlled devices. This work also deals with the issue of EEG signal measurement and its further analysis, how to choose the right sensor, and right design and construction of the device for data collection, amplification and filtration of the signal obtained by the selected sensor. Further, this project aims to develop software for translation (transformation) of the obtained data in order to enable communication and control of external devices.

Indikator position behind the wall
Pecha, Václav ; Marcoň, Petr (referee) ; Szabó, Zoltán (advisor)
The work sums up the basic measurement principles for different kinds of searching devises. It deals with measurement using resonance. The feature of resonance and measurement techniques are described to set the location of the radiating circuite. The work contains the design of a locator of position behind a wall itself as well as the concrete switch connection, schema and description of receiver and emitter in the circuit.
