IMS based multimedia services
Novotný, Roman ; Nagy, Ľuboš (referee) ; Mácha, Tomáš (advisor)
Submitted work describes IMS (IP Multimedia Subsystem) and focuses on services offered by this technology. In the theoretical part of the thesis is a detailed description of the IMS architecture, in the terms of its components and interfaces. Also a SIP protocol is described as the main signalling protocol, which represents the basis of the IMS architecture and RTP protocol that allows the transmission of multimedia data in real-time. Further, there are provided services that the IMS system brings. The practical part of the work describes the design and implementation of services within the IMS. It is a client-server service. Server part of the system is implemented as a SIP Servlet application. It has access to the MySQL database, which stores records of multimedia files. Client registered in the IMS network can communicate with the SIP servlet sending a request for information on such files. Following this communication, the client can play the file in his online ICP application, or download it into his PC and then play. To play and view multimedia fines is used JMF. The service is implemented in a development environment SDS Ericsson 4.1, which allows simulation of the IMS network.

Multipurpose bicycle alarm
Albert, Matej ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
This diploma project is about designing a concept of an anti-theft tracking device for a bicycle. The device is equipped with a GNSS module for tracking of current location, GSM module for sending the location data in case of a theft and a BT module for user settings via mobile phone. The bike theft detection is detected by an accelerometer. The final goal of this project is a concept of such a device for evaluation and improvement purposes.

Interaction of Lanthanide trichlorides with the construction materials of a purification apparatus
Novotný, Radoslav ; Zmrzlý, Martin (referee) ; Richtera, Lukáš (advisor)
Lanthanide halides LnX3 are the base material for preparation a different compounds, but also the pure metals. Our faculty is used for the syntesis organometallic catalyst. This compounds are very sensitive to the presence of moisture and oxygen. Lanthanide halides are commercially available in anhydrous or hydrated form. This thesis is devided eight chapters and deals with matherial of the apparatus, which is designed to sublimation of anhydrous lanthanide halides. Initial chapters described the properties and preparation this substances. Following are on the sublimation and corrosion materials. In the last chapter is the skeleton sketch, layout and a availability parts of construction. The aim of this work was to create theoretical basis of construction aparatus and commissioning.

Home automation, input and output modules
Ponechal, Mikuláš ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
The bachelor´s thesis mediates theoretical analysis of home automation using IoT application. The aim of the thesis is to desing input and output modules to make controlling of electronic devices easier for user. The first chapter describes wireless technologies which are mostly used in IoT applications, principles of measuring current in order to determine energy consumption and ways how to dim lights. The second chapter includes design of wireless communication between the modules and a central control station and specific module designs. The third chapter deals with the construction and testing of hardware modules.

IO/Link interface implementation to pressure sensors
Pešl, Jiří ; Novotný, Radovan (referee) ; Kadlec, Jaroslav (advisor)
This thesis is concerned with the measurement of physical quantities. Thesis describes sensors in general terms and requirements, which delivers latest trends in the field of automation. The main theme of this thesis is sensors for meassuring pressure, and their connection to the automation chain. In the next part thesis describes the design of the converter for connecting SMART sensors for pressure measuring, that use HART communication protocol, to the automation systems managed by a communication protocol IO-link. First will be described in detail various communication standards by their ISO OSI model, and on this theoretical basis will be based design of converter between communication protocol HART and communication protocol IO-Link. The last part will be Designed software for this converter.

Setting control of alkali-activated systems
Komosná, Kateřina ; Novotný, Radoslav (referee) ; Kalina, Lukáš (advisor)
This thesis is focused on the possibilities of setting control of alkali-activated systems based on blast furnace slag. The aim of this work is finding the suitable retarder that most extends the time of setting and also preserves the mechanical properties of alkali-activated material. In experimental section were prepared samples of blast furnace slag, water glass, water and additives in various weight addition. Testing samples have undergone of flexural and compressive strength tests. Then the setting time was determined using the Vicat device. The samples were measured calorimetrically because of monitoring the setting process. Finally the mixtures were observed using scanning electron microscope for a closer view on the structure of samples and distribution of setting retarder.

Wireless weather station
Filka, Tomáš ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
This diploma thesis deals with a draft of wireless weather station, whose task is to measure basic values inside and outside the home. Measured variables are for example temperature, atmospheric pressure, relative humidity, wind speed and direction or concentration of carbon dioxide (CO2). These data will be transmitted to a web server for later processing. Possible technical solutions are described and the outcome is a designed printed circuit boards, which has been assembled and tested. Resulting system was tested in trial operation.

Value stream analysis and improvement
Malec, Tomáš ; Hégr, Ondřej (referee) ; Novotný, Radovan (advisor)
This thesis deals with the general analysis and value stream improvement. The theoretical part describes the difference between functional and procedural model of company management, mutual benefits and disadvantages of these systems. The thesis deals with the mapping process, subdivision maps and methodology of process maps creation. The work also includes software analysis for process mapping. Next section contains search of selected optimization tools and methods to improve production flow and description of the principles of controlled documentation. In the practical part is realized mapping process of bachelor studies at FEKT and map of production process at ABB switchgear.
