Development of System for Landmine Detection
Šmelka, Martin ; Kubíček, Michal (referee) ; Doležal, Tomáš (advisor)
The Bachelor's thesis will cover a proposal for the construction of a demonstration system designed to discover objects that represent hidden „mines“ in a field. In the first phase, a systém will be designed to simulate the behaviour of the final device using the MATLAB interface. The proposed code will generate a GUI that will simulate the system in the field. After discovering a mine, the assigned cell will be marked, and the location will be signalled to the operator. Afterwards, the design of the demonstrator will be conceptualised and a working prototype fabricated to verify the functionality of the proposal.

Běhová prostředí pro testování činnosti rozšíření pro webový prohlížeč
Petráňová, Jana ; Dolejška, Daniel (referee) ; Polčák, Libor (advisor)
This thesis briefly describes how users are being tracked across the internet while browsing and names the most popular browser extensions focusing on security and privacy. It focuses on the JShelter project and its testing, which is used as a fundamental basis for the proposed implementation of the run-time environment. It also mentions the PETInspector project, which is redone and used as a framework for testing. It presents a possible design of the run-time enviroment implementation, which is later implemented. The implementation is summarized and used for various tests, including those that affirm its ability to fulfil defined conditions. Finally, the tests results are presented and interpreted.

Automated segmentation of the diadochokinetic task for remote monitoring of hypokinetic dysarthria
Svojanovský, Jan ; Mekyska, Jiří (referee) ; Kováč, Daniel (advisor)
The study describes health problems associated with Parkinson’s disease, especially hypokinetic dysarthria. It also points out the subjective and objective methods used to determine the severity of the disease. One of these methods is a diadochokinetic (DDK) task based on rapid syllable repetition to test the functionality of the articulatory apparatus (e.g., tongue, lips, or vocal cords). Correct speech production can also be examined by a speech therapist in the 3F test, which scores the severity of disorders in different areas of speech production. Next, the approaches of other authors, also dealing with the automated search of syllables in the speech signal, are described. The thesis also discusses some features of human speech that are needed for training a machine learning model. These features were computed for each of the 30 ms segments of a DDK task. The main goal is the automated detection and classification of [Pa]-[Ta]-[Ka] syllables in the recordings. For this purpose, an algorithm using a logistic regression was applied. The resulting average accuracy of syllable detection in the recordings was 89.4 %, average sensitivity 59.0 % and average specificity 93.79 %. The identification of individual syllable types was successful with an average accuracy of 90.78 %, an average sensitivity of 59.0 % and an average specificity of 95.39 %. Considering that the predicted onset was not located directly on the manually annotated onset, but in its close vicinity (up to ±3 segments), the average detection sensitivity and average syllable type classification sensitivity were 96.9 % and 85.1 % respectively, with an average difference between manually annotated and automatically segmented syllable onsets of 10.35 ms. The average accuracy of classification of speakers into healthy and PN patients using logistic regression (with speech parameters obtained after automated segmentation) was only 43.92 %, sensitivity 70.0 % and specificity 30.61 % (threshold 70 %). Using linear regression, the clinical scores of the 3F test were predicted. For faciokinesis, the root mean square error (RMSE) was 2.764 after manual syllable annotation and 3.271 after automated segmentation. The RMSE values for phonetics were 3.657 (manual) and 0.753 (automated). The developed algorithm can detect syllables in DDK tasks with relative success, and thus it is possible to determine parameters quantifying speech disorders with low differences with manual segmentation. If the recordings of DDK tasks meet the conditions for computing all these parameters, the algorithm could be used to classify speakers into healthy subjects and PN patients, for whom it could additionally assess the severity of dysarthria.

Cartesian manipulator
Bačkovský, Tomáš ; Arm, Jakub (referee) ; Benešl, Tomáš (advisor)
This bachelor thesis deal with the design of the control of an industrial two-axis manipulator, which will serve as a palletizer of egg spacers. Part of the work is the theory and selection of actuators, description of individual parts of the manipulator. The practical part deals deals with designing of complete electrical documentation, completion of control software and visualization of the panel. Finally, the individual parts are tested on a real manipulator.

Automation of RC Models Control with Videocamera
Záň, Drahoslav ; Beran, Vítězslav (referee) ; Zemčík, Pavel (advisor)
Nowadays, there is a big variety of RC models, but their use and control is basicaly the same. The aim of this thesis is therefore a modification of suitable RC model in such way, that it can be controlled via PC. The model is equipped with a computer plus video camera and using wireless technology is enabled video transmission into the final destination. This modified model can be used as a simple tool to explore an unknown terrain, or for spying purposes.

Detection of spatial objects in a point cloud
Venený, Petr ; Machotka, Radovan (referee) ; Volařík, Tomáš (advisor)
The diploma thesis deals with processing of a point cloud that was collected via mobile mapping system. The first part sets a theoretical background, starting with mapping in general moving to mobile mapping systems and their particular parts. The practical part describes the whole process of data collecting, testing the automatic detection of spatial objects based on a point cloud and its visualisation. The results of the diploma thesis are GIS data layers and an evaluation of the process.

Automatic Honeypots Deployment and Data Gathering
Ďuriš, Tomáš ; Pluskal, Jan (referee) ; Zobal, Lukáš (advisor)
This work deals with honeypots deployment automation, data collection from honeypots and the deployment of a monitoring system with alerts. The aim was to study the issue of honeypots, choose tools for their deployment, maintenance and collection of provided data together with creation of automatic deployment system for multiple types of honeypots. The first part of the work is devoted to the theory of honeypots, their distribution and type. Furthermore, the work mentions the comparison of individual configuration tools. The practical part is devoted to the use of a selected configuration tool Ansible in cooperation with existing open-source applications to build a fully automated system for the deployment and monitoring of honeypots, collection of provided data and their visualization.

Automatic Generation of Test Cases from Data-Flow
Kraut, Daniel ; Fiedor, Tomáš (referee) ; Smrčka, Aleš (advisor)
This thesis deals with automatic generation of test cases on Unit testing level for source codes in C language. In order to achieve automatization are used methods of approach to software as a Data-flow of variables. There is outlined a process of creating tests here as well as a function of CSP solvers which are necessary part of solving this problems. Static code analysis is accessed with LibTooling libraring as part of a compiler front-end project Clang. Output of a developed application are provided here which is automatically generated input values for test cases.

Application for Data Presentation and Modification in Mobile Devices
Kučera, Pavel ; Ryšavý, Ondřej (referee) ; Trchalík, Roman (advisor)
This thesis is aimed to study the possibility of usage of mobile devices in the sphere of automation. One automation company needed to have in hand some PDA-based tool for a remote control of the technological process. There is analysis of ability of contemporary portable devices to run a application software. According to the specified requirements there is designed and implemented the client-server system based on the VNC technology. The server is a Linux-based PC server implemented using Xinetd daemon and the Xvnc. The two standard VNC clients were made. A free software available under the GPL license was modified to implement them. One runs on Windows Mobile operating system and the other one is a Java MIDlet.
