The impact of HVAC systems on the acoustic microclimate of clean rooms
Jelínek, Ondřej ; Mathauserová, Zuzana (referee) ; Papež,, Karel (referee) ; Rubina, Aleš (advisor)
The work description is to create a system of measures to prevent the spread and the consequent attenuation of sound in air handling systems serving the cleanrooms. The thesis presents a solution to noise attenuation in the investigated area, and in HVAC duct, which uses a commercially available material in the form of sound insulation hoses. In the systém solution is part of the work focuses on the optimal design of terminal elements to distribute air in a clean room. Processing methods utilize theoretical and experimental approach. The experiment comprises a unique analysis of the sound insulation properties of selected products under specific conditions. The data obtained are analyzed and incorporated into the framework of this work created program module for determining the attenuation and noise propagation in an enclosed space. Math and physical dependence are programmed into their own DLL by programming language DELPHI.

Cinema air conditioning
Ilko, Miroslav ; Jelínek, Ondřej (referee) ; Rubina, Aleš (advisor)
The bachelor's thesis deals with the design of an air-conditioning system in selected areas in a cinema building. There are designet two air-conditioning units. Equipment No. 1 provide the air quality in the cinema hall, in the sound engineer's room and in the projection room. Equipment No. 2 provide the air quality in the cinema facilities, intended mainly for visitors. The devices are designed to meet hygiene, operational and safety requirements and to provide optimal microclimatic conditions. The air conditioning system ensure the coverage of heat losses and profits, the supply and exhaust of fresh air in the premises. The theoretical part of the work is focused on air filtration.

Image similarity measurement using points of interest
Jelínek, Ondřej ; Uher, Václav (referee) ; Burget, Radim (advisor)
This paper presents a new object detection method. The method is based on keypoints analysis and their parameters. Computed parameters are used for building a decision model using machine learning methods. The model is able to detect object in the picture based on input data and compares its similarity to the chosen example. The new method is described in detail, its accuracy is evaluated and this accuracy is compared to other existing detectors. The new method’s detection ability is by more than 40% better than detection ability of detectors like SURF. In order to understand the object detection this paper describes the process step by step including popular algorithms designed for specific roles in each step.

Evaluation of the operation of the air handling heat recovery system for ICU
Dobrovolná, Natálie ; Jelínek, Ondřej (referee) ; Rubina, Aleš (advisor)
The diploma thesis deals with the issue of heat recovery systems. In the first part the thesis deals with the types of recovery systems in general, their evaluation, possibilities of use and design. The second, computational part, of the thesis focuses on three specific variant solutions of the design suitable for clean hospital premises of the intensive care unit. The aim is to apply the theme to a specific building and evaluate the individual proposed variants in terms of indoor air quality, spatial requirements and operational economy. The last part is dedicated to experimental measurement and subsequent evaluation of the measured data of real air-conditioning system. The essence of the measurement was to evaluate the operation and verify the heat recovery efficiency of a real plate heat exchanger installed in the air-conditioning unit serving the premises of the intensive care unit.

Air conditioning in the production hall
Myjavec, Patrik ; Jelínek, Ondřej (referee) ; Blasinski, Petr (advisor)
The bachelor thesis deals with the project of air-conditioning system in the manufacturing hall, storage and administrative premises. Each system is designed to fulfill the operational, functional and sanitary requirements of inner microclimate. System No. 1, for the manufacturing hall, is designed to be able to cover loss of heat in winter time and heat gain in summer time. System No. 2, for storage premises, serves for heat ventilation all year round. System No. 3, for administrative premises, is designed as heat ventilation accompanied by VRV cooling system to cover heat load in summer time. Theoretical part focuses on natural ventilation, its principles and division.

Ventilation and cooling of administrative building
Kotas, Marek ; Blasinski, Petr (referee) ; Jelínek, Ondřej (advisor)
The Bachelor thesis introduces a design of ventilation and air-conditioning equipment for an administrative building. The function of the device is to create a high-quality internal microclimate. The system ventilates the building and covers heat losses and gains caused by ventilation. In summer, cooling of the selected rooms is provided by the refrigeration circuit. The theoretical part of the thesis distinguishes between different types of air-conditioning systems, it describes the types of refrigerants and deals with the limitation of refrigerants in connection with the protection of the environment. The computational part deals with the complete design of ventilation and air conditioning equipment, including the necessary calculations. The last part of the thesis introduces the project itself.

Ventilation of the library
Martinčič, Jakub ; Jelínek, Ondřej (referee) ; Blasinski, Petr (advisor)
The bachelor thesis deals with the project of air-conditioning system in the library building with study room, classrooms, hall and book stores. Each system is designed to fulfill operational, functional and sanitary requirements of indoor microclimate. System No. 1 (1. S) and system No. 2 (1. NP) are designed to be able to cover heat losses in winter time and heat gain in summer time. System No. 3 which is for the entire 3. NP is designed for complete air conditioning (hot-air ventilation). This system is complemented by VRV cooling system. The theoretical part is focused on the problems of acoustics in ventilation.

Airconditioning of the exhibition space
Dokládalová, Tereza ; Jelínek, Ondřej (referee) ; Rubina, Aleš (advisor)
The point of this bachelor thesis is to design two air-conditioning units specifically made for assigned facility with exhibition purposes - archeopark. The units are designed in a way to accomplish operational, functional and hygienical requierements of indoor microclimate. The purpose of these units is to ventilate, cover the heat loss, elimination of heat load, humidification and dehumidification of air. Teoretical part of this thesis deals with indoor microclimate and its influence on a quality of life and also covers terms such as SBS, BRI, PMV and PPD.

Geolocation of Internet nodes using domain name analysis
Jelínek, Ondřej ; Verner, Lukáš (referee) ; Komosný, Dan (advisor)
Goal of this thesis is to create an application for geolocation of hosts using an analysis of domain names. The theoretical part of the thesis focuses on estimation of geographic location of hosts in the Internet (called geolocation) and the DNS system. This knowledge is necessary for creation of the application. The first task is to choose suitable method of geolocation. The next step is to fully undestand the DNS system and function of domain names. Finally, the application for analysis of domains in JavaFX Script programming language is created. The practical part of the thesis describes this application, its structure, function and results. Acquired data are analysed and compared to results of other geolocating methods.
