Deep Learning for Object Detection
Pitoňák, Radoslav ; Dobeš, Petr (referee) ; Teuer, Lukáš (advisor)
This thesis analyzes different object detection methods which are based on deep neural networks. In the beginning, the convolutional neural networks are described and commonly used object detection methods are compared. In the following parts, the proposal and implementation of the object detection model trained on the specific dataset are described. In conclusion, the achieved results of this model are discussed and compared with the results of other methods.
Android App for Security Monitoring of Communication
Klepáčková, Karolína ; Dobeš, Petr (referee) ; Herout, Adam (advisor)
This diploma thesis is focused on implementation of application for security monitoring of network communication of other applications in mobile device with Android platform. Provides users information about security risks that may harm his/her privacy or device. It uses a local VPN to tunnel all data sent to the wireless network. These can be linked to an application that has sent them because the Android kernel is derived from the Linux kernel and can be used to retrieve information about established network connections and the application identifier associated with the connection. This mapping allows to get more information about an app that is potentially dangerous for your mobile device.

This report summarizes the work and partial results made under the Public Procurement Obtaining Data from the deep horizons of the Rožná Mine in the first phase of the third and fourth subdivisions from February to November 2018. These are in particular technical works (boreholes, access to corridors),seismic measurements, sampling for laboratory analysis (physical-mechanical properties of rocks, breakage fills, bearing revalidation), structural characterization of the rockanalytical work on all samples taken. Parallel to these works3D models are being prepared, especially data preparation for modeling.
Information System and User Interface for Career Fair
Pavlík, Tadeáš ; Bartl, Vojtěch (referee) ; Dobeš, Petr (advisor)
This work focuses on the design and implementation of an information system and user interface for day of career opportunities at Olomouc grammar school. The aim of this thesis is to design an information system and user interface through which the presenters can apply for the event, the organizers can manage the event and interact with the visitors of the event. This thesis focuses on implementing an clear and easy - to - use user interface. The information system is implemented using Laravel framework, PHP language and Bootstrap 3 library. The thesis presents the design and implementation of database structure, use cases, information system and user interface. Testing was carried out using participants from previous years. The resultant information system is ready for deployment. The contribution of this work is simplifying the work of the organizers, providing visitors with information and getting information easily on mobile devices.
Determination of binary phase diagram
Dobeš, Pavel ; Havlík, Petr (referee) ; Jan, Vít (advisor)
This bachelor's thesis deals with the analysis and verification of binary diagram of the Ag-Sb system. The theoretical segment of the thesis describes the sub-elements of this system, the function of binary diagrams and the methods of thermal analysis. The experimental segment mainly deals with the interpretation of DSC signal, the analysis of the microstructures of specific Ag-Sb system samples and the comparison of the acquired data with the given binary diagram.
New data on the origin of the Fe-Cu-As skarn deposit at Obří důl, West Sudetes, Bohemian Massif
Pašava, J. ; Veselovský, F. ; Dobeš, P. ; Erban, V. ; Pour, O. ; Žák, Karel ; Ackerman, Lukáš ; Haluzová, Eva ; Creaser, R. ; Tásler, R.
The Obří důl Fe-Cu-As sulfide deposit is hosted in metamorphosed lenses of marble, calc-silicate rocks and skarns. The deposit is located up to a few hundred meters away from the contact of the large, late-orogenic Variscan Krkonoše-Jizera Plutonic Complex (KJPC). Mineralogical and fluid inclusion studies of the Gustavská ore lens show that the main sulfide stage, dominated by pyrrhotite, chalcopyrite and arsenopyrite, originated from water-rich hydrothermal fluids with salinities up to 8 wt.% NaCl eq. at temperatures ranging from 324 to 358°C.These fluids replaced mainly the carbonate-rich lithologies. The 34S values indicate a magmatic source of sulfur and Re/Os dating of molybdenite are consistent with simultaneous formation of the main sulfide stage ore and the KJPC.
Reconstruction of 3D Information about Vehicles Passing in front of a Surveillance Camera
Dobeš, Petr ; Sochor, Jakub (referee) ; Herout, Adam (advisor)
This master's thesis focuses on 3D reconstruction of vehicles passing in front of a traffic surveillance camera. Calibration process of surveillance camera is first introduced and the relation of automatic calibration with 3D information about observed traffic is described. Furthermore, Structure from Motion, SLAM, and optical flow algorithms are presented. A set of experiments with feature matching and the Structure from Motion algorithm is carried out to examine results on images of passing vehicles. Afterwards, the Structure from Motion pipeline is modified. Instead of using SIFT features, DeepMatching algorithm is utilized to obtain quasi-dense point correspondences for the subsequent reconstruction phase. Afterwards, reconstructed models are refined by applying additional constraints specific to the vehicle reconstruction task. The resultant models are then evaluated. Lastly, observations and acquired information about the process of vehicle reconstruction are utilized to form proposals for prospective design of an entirely custom pipeline that would be specialized for 3D reconstruction of passing vehicles.
War Powers of the U.S. President in War Against Terrorism: A Case Study of President Bush's Military Order for November 13, 2001
Dobeš, Petr ; Sehnálková, Jana (advisor) ; Raška, Francis (referee)
The subjects of this thesis are the war powers of the U.S. President. The main theory of this work is that from the beginning of the 20th century, there is the trend of expanding presidential powers and a strong executive which peaked during the presidency of George W. Bush under the influence of extraordinary circumstances that had been in place after the terrorist attacks of 9/11. This theory will be proved by the case study of a Military Order of November 13, 2001 regarding Detention, Treatment, and Trial of Certain Non-Citizens in the War Against Terrorism issued by president George W. Bush and by the analysis of communication between certain members of the executive. This thesis seeks answers to questions whether the U.S. Constitution is able to cope with the threat of global terrorism, in what ways President Bush overstepped his constitutional authority and whether the presidency of George W. Bush could be regarded as a case of an "imperial presidency" as described by Arthur Schlesinger Jr.
Genesis of Au-Sb ores at the Krásná Hora deposit
Němec, Matěj ; Zachariáš, Jiří (advisor) ; Dobeš, Petr (referee)
Ore deposits of the Krásná Hora ore district are the main representative of the Sb-Au mineralization in the Czech Republic. It can be classified genetically as epizonal subtype of orogenic gold deposits. Spatially and partly temporally are associated with the intrusion of the Central Bohemian Pluton. The ore bodies are related to quartz veins that follow the course of E-W striking lamprophyre dykes, which are usually heavily crushed and altered. Ore shoots with massive stibnite are located mainly at the intersections of these E-W trending veins with the NW-SE striking tectonic fault zones. Au-Sb ores at Krásná Hora ore district formed in an area of repeatedly activated fault zones. Three generations of hydrothermal quartz were identified on microscopic scale. Earliest quartz (Qtz1), which was considered in the literature auriferous originated from low-salinity H2O - CO2 fluids at ~350 řC and at a depth of about 5 km. The younger quartz (Qtz2) originated at lower temperatures of about 260 řC and lower depth of about 3-4 km from low/saline aqueous fluids. Both older (Qtz1) and younger quartz (Qtz2) are not auriferous. The gold is associated with younger paragenetic formation (Anti + Au + Cc + Qtz3) that fills in intergranular spaces and fractures in Qtz1 and Qtz2 . Due to the partial exhumation of the...
