Car Driving Simulator
Michalík, David ; Fiedler, Petr (referee) ; Jirgl, Miroslav (advisor)
This master’s thesis is mainly focused on creating our own car driving simulator and basic data gathering from the driver’s input. To achieve this goal, the thesis includes introduction to man-machine systems and basic information about functions and runtime game engine employs. Research about commonly used open source game engines is also presented with a detailed focus on the engine we chose - Unreal Engine. In conclusion ofthis thesis, a full version of a car driving simulator is created with gathered data analysis.

Monitoring Service Properties of an IPFIX Collector
Kala, Jan ; Žádník, Martin (referee) ; Wrona, Jan (advisor)
This bachelor's thesis addresses possible ways of monitoring IPFIX collector, which is used for the collection of metadata about network traffic. The thesis briefly introduces the pro- blematics of monitoring and describes the current state of IPFIX collector, which is being developed by an organization called CESNET. It also describes service properties, which can be monitored during the process of data collection using the IPFIX protocol. A new plugin is described, which is intended for the collection and the export of service properties. The thesis describes an implementation and contains results of testing of the new plugin.

Management System for Facebook Marketing Campaigns
Stejskalová, Andrea ; Bartík, Vladimír (referee) ; Hynek, Jiří (advisor)
The main goal of this bachelor thesis is to design and implement a management system for Facebook marketing campaigns. This system is designed to easily manage marketing campaigns of Facebook pages via Messenger. It also allows processing results to determine the following marketing goals. The system is written in PHP framework Nette. It was designed according to the requirements from the Q2 Interactive company because there was not found any suitable existing solution on the internet. The system will be used to manage Facebook campaigns.

Server load monitoring
Fišer, Martin ; Čejka, Rudolf (referee) ; Dytrych, Jaroslav (advisor)
The goal of this thesis is to design and implement a new system that will perform the server load monitoring and will be part of the KNOTIS information system. This thesis analyzes the problems of the server load monitoring system already implemented in KNOTIS. The entire new load monitoring system is based on data collecting, which is performed periodically on all servers where the monitoring is currently running. The collected data is checked and then stored in the database. Presentation of these data is made by creating clear graphs and tables that are plotted on the new KNOTIS pages that were also created as part of this thesis. The new system has been deployed and has been proven to significantly save overhead and database space.

Intelligent Recognition of the Smartphone User's Activity
Pustka, Michal ; Goldmann, Tomáš (referee) ; Drahanský, Martin (advisor)
This thesis deals with real-time human activity recognition (eg, running, walking, driving, etc.) using sensors which are available on current mobile devices. The final product of this thesis consists of multiple parts. First, an application for collecting sensor data from mobile devices. Followed by a tool for preprocessing of collected data and creation of a data set. The main part of the thesis is the design of convolutional neural network for activity classification and subsequent use of this network in an Android mobile application. The combination of previous parts creates a comprehensive framework for detection of user activities. Finally, some interesting experiments were made and evaluated (eg, the influence of specific sensors on detection precision).

A New Generation of an IPFIX Collector
Huták, Lukáš ; Žádník, Martin (referee) ; Wrona, Jan (advisor)
This master's thesis addresses processing of flow monitoring records from a point of view of an IPFIX collector. It analysis the current solution of the modular collector, which went through considerable historical development, and focuses on revealing its strengths and weaknesses. Based on acquired knowledge, a new collector is designed. The new solution, which significantly modifies individual components for processing of flow records, focuses on high throughput and adds missing functionalities. The document also compares performance of both generations and the new collector clearly dominates.

Design of datalogger for production machine
Gazda, Ondřej ; Kovář, Jiří (referee) ; Andrš, Ondřej (advisor)
This thesis describes the design of the data datalogger for collecting the operating data of the machine tool. Dataloggers and data acquisition systems are used in scientific research as well as in the industry for recording and analyzing large amounts of data. The control unit of the proposed system is the National Instruments CompactRIO platform. System software is created in the LabVIEW programming environment and uses both the FPGA circuit and the real-time processor of the control unit. Measured data are stored on the unit and in the database. The measurement status is reported via email.

Design and realization of the measuring amplifier of mechanical quantities
Kaplan, Tomáš ; Chalupa, Jan (referee) ; Krejčí, Petr (advisor)
Subject of this effort is development and realization of one-channel data acquisition unit of mechanical quantities and it’s PC software application. Usage of this data acquisition unit is aimed on applications, where resistive strain gages wired as Wheatstone bridge with AC excitation are used. Output voltage of Wheatstone bridge is amplięed, demodulated with excitation voltage, filtered and level shifted for analog to digital conversion via AD converter. Converted digital data are sent via serial bus into microprocessor which sends them into PC for further meaningful representation in software application. Besides sensing bridge output voltage, data acquisition unit also generates AC excitation of Wheatstone bridge. This excitation voltage is generated via DA converter which communicates with microprocessor and converts incoming digital data into analog sine waveform. There is precise voltage reference circuitry for both of these converters. PC application’s task is to visualize measured data in meaningful form and to give tools for further work with measured data. It’s programmed in Python language and it has one independent thread which does reading and computing of incoming data and there is also class which builds graphical user interface and plots measured data into live graph.
