The Operation Assessment of Filtration Units
Hanušová, Veronika ; Biela, Renata (referee) ; Kučera, Tomáš (advisor)
The first part of this bachelor's thesis deals with knowledge of water works filtration gathered from Czech and foreign literature. Following this information is a group of criterions evaluating the working of filtration units themselves. Water treatment in Hrobice and Kroměříž is assessed in the second part of this thesis.

Options eliminate odors in sewer network
Žíla, Radim ; Malaník,, Stanislav (referee) ; Hluštík, Petr (advisor)
The diploma thesis focuses on the possibility of removing odor on the sewer network. The first part of the research describes how the odor is generally perceived and what legislation regulates its quantity in the air. The second part of the research focuses on problems of formation of smelting sulfate on the sewer network. This section describes the formation of sulfane as a major component of odor. Further disclosed are methods for its removal, and the ways in which the odor is measured. The practical part deals with laboratory testing of pre-selected fillings in order to determine their ability to remove odorous sulfane. In the second part, on-line measurements are made to determine the causes of sulphan formation in a given location.

ECG signal classification
Smělý, Tomáš ; Harabiš, Vratislav (referee) ; Hrubeš, Jan (advisor)
This thesis deals with classification of different types of time courses of ECG signals. Main objective was to recognize the normal cycles and several forms of arrhythmia and to classify the exact types of them. Classification has been done with usage of algorithms of Neural Networks in Matlab program, with its add-on (Neural Network Toolbox). The result of this thesis is application, which makes possible to load an ECG signal, pre-process it and classify its each cycle into five classes. Percentage results of this classification are in the conclusion of this thesis.

Implementation and analysis of control circuits in MATLAB/Simulink
Hanuš, Tomáš ; Houška, Pavel (referee) ; Singule, Vladislav (advisor)
The thesis is focused on comparing the characteristics of the most common types of controllers. This comparison is done in MATLAB / Simulink to model the DC motor. First, in the thesis, theoretical description of all structures controllers that are tested. This is specifically the PID controllers, PSD, PI-D, PS-D, S-PD, I-PD, PID filtering of derivative and PSD also with this filtration. Then there is the function given the DC motor and its mathematical description. In the last section of the theoretical part describes the different methods of setting regulators. In conclusion, this thesis compares the structure of individual regulators. There are the results. A comparison of their behavior with position control of DC motor.

Additional Treatment of Drinking Water at the Point of Consumption
Hrubý, Ladislav ; Biela, Renata (referee) ; Kučera, Tomáš (advisor)
This bachelor’s thesis deals with problem of pollution in drinking water during its transport towards consumers. It particularly deals issues with heavy metals such as lead, copper and sums up methods which can be used when trying to remove such metals at water connections or taps. Next, particular filter materials are described together with processes that happen during filtration. Finally, a short experiment has been performed for finding out the most appropriate filter material.

Airconditioning in healthcare facilities
Růžička, Věroslav ; Jelínek, Ondřej (referee) ; Rubina, Aleš (advisor)
This bachelor thesis deals with design of air conditioning equipment serving the spaces of hospital inpatient ward and its associated facilities. Equipments designed in the computational part have the task to transport adapted fresh air to hospital premises. The system is devided into two units. Primary mechanism operates bedrooms and their sanitary facilities. Secondary mechanism operates associated facilities. Both mechanisms are designed so that hot air can ventilate in winter. To cover the heat load in summer, fancoil units are designed. Device number one is also able to manage the treatment of humidity. The theoretical part of the thesis focuses on air filters and filtration of atmospheric air.

Design of audio power amplifier with Bluetooth connectivity
Bartoň, Jan ; Šotner, Roman (referee) ; Brančík, Lubomír (advisor)
This bachelor‘s thesis deals with the task of designing an audio amplifier, operating in class D, with a nominal output power of 2 x 80 W with Bluetooth connectivity, supplemented by an equalizer and a state display. A power supply and a user interface are designed as well. At first, research regarding audio amplifiers is made, followed by a more thorough description of class D operating principles. Afterwards the actual synthesis of the desired amplifier is presented, followed by the power supply design procedure. The correctness of the synthesis is later verified by simulations in PSpice and LTSpice. Theoretical design is then practically built, and its parameters are confronted with expected values by measurements.

Secure Network Based on Virtual Next-Generation Firewall
Varmus, Pavol ; Burda, Karel (referee) ; Malina, Lukáš (advisor)
The bachelors thesis aims to study the issue of security of the networks that use firewalls. The next goal is to evaluate the characteristics of a different types of firewalls and to summarize its results. The other object is to design a small or medium sized network with description of best practice. The main objective of the thesis is to design a lecture task for students to test with a step-by-step solution. This task is for students to undertand the importance of firewalls as a network protection service tools and to try out different types of filters for maintainin network security. The task ends with a practical stress test made by a network attack in order to see its resistance to the attack.
