The following diploma thesis deals with the management of asynchronous motor revolutions by a frequency converter MICROMASTER 440 via the programmable controller S7-200. At the beginning, I researched the company documentation of Siemens, which is the producer of the frequency converter and the programmable controller mentioned above. As my work proceeded, I also started to study the company documentation of Mitsubishi Electric, which produces the operating pannel. The first part of my thesis provides a general description of the stated devices and the second part deals with the solution of the task itself. My task was to design a way of communication between the converter and the controller. I chose a USS protocol via serial port RS-485. The operation of the controller was performed by using an operating terminal type GOT1000 which was connected to the controller. In summary, my diploma thesis primarily deals with the construction of an operating programme for the controller and with creating of a graphical control on the terminal. In the end, I evaluated the knowledge gained during the work on this subject and suggested further procedures.

One of the software success condition on the software market is permanent development to keep in condition with actual technical tools. That is the reason why SAS software is searching for a way how to fulfil customer's requirements better. The change to the distributed system architecture brings new opportunities and sets up competitive advantage for SAS concurrently. The subject of this thesis is to create the design of movement to the distributed system. The main reason is to make analysis, design and partial implementation meeting functional requirements of the new architecture.

This Master's thesis deals with design and implementation of a system that can access remote devices through computer network. Specifically, the serial port devices and audio input devices. The first step of the thesis was to do a survey in the field of similar available, focusing on applications that could be integrated into the final system. For serial port devices, it was necessary to find a solution that would allow redirecting data from the physical device to a computer network and creating virtual serial ports on client systems, through which would users access these devices. To transfer audio streams from audio input devices through computer network was chosen RTP protocol, which is well suited for data transmission in real time. The thesis also contains the description of handling received RTP stream on a client system. The result is a complex system that integrates the functionality of mentioned tools into a single unit.

This thesis deals with design and implementation of programming structure of game web portal. The web portal will serve as a communication and information center to simplify coordination among players and allow them to gain new experience. In the thesis are analyzed the needs of players, existing solutions and their drawbacks. The results of this analysis are used to design individual functions of the portal. Implementation of the most important parts of the website has been described, the implementation of these parts were evaluated and some enhancemets were eventually suggested. In the end of this thesis several functionalities were suggested, which could extend the portal in the future.

This thesis is focused on smart buildings where communication and automatization technologies are deployed. It includes overview and description of frequently applied network protocols in smart homes and their side by side comparison with an emphasis on Thread networking protocol. The next chapters describe details and parameters of used development boards provided by NXP Semiconductors and their implementation in a smart home model. Subsequent chapters are focused on hardware and software components which are the basis for smart home model’s internal workings. The last chapter highlights how a physical model of a smart home was developed with suggestions for future improvements.

This graduation thesis is aimed at design and implementation of embedded systems, network communication and support of the network communication for embedded systems. Furthermore it introduces school platform FITkit and offers a conceptional extension of the network interface for this platform based on Ethernet network standard. Based on that conception I'm trying to find and describe suitable solution for FITkit platform which realizes a network interface as a form of extension module capable of development supporting.

This masters thesis is about mutlicast. There are explained 2nd and 3th layers of the ISO/OSI model multicast addressing. Routers in a network use multicast routing protocols to optimally route multicast packet through the network, this is also in this project. These multicast protocols are DVMRP, protocol PIM in his two modes, PIM Sparse Mode and PIM Dense Mode. Protocol DVMRP uses protocol IGMP, which is described as well. At practical section of this masters thesis is presented connections, by which tests was executed.

The thesis is focused on the topic of virtual cryptocurrency Bitcoin. The theoretical part is divided into several chapters. First of all, there is a chapter containing basic information about the currency's history, its development to the present, as well as principles of operation of this currency. Because it is a currency based on cryptographic principles next chapter summarizing cryptographic techniques, which is necessary to know for subsequent analysis of this currency. In other parts is elaborated a detailed analysis of the principles of Bitcoin. The main point of this analysis is a system of transactions, decentralized history, then joining the transactions into blocks and in the end creating blockchain. It also explains the principle of P2P networks. The practical part of this work focuses on the analysis and design of payment applications for mobile devices. There used open-source libraries such BitcoinJ. The application is developed in Java programming language with plugin for portable devices, which work under the operating system Android. For the purposes of analysis and design of graphical user interface is used UML diagrams. The specification of the UML diagrams was utilized by freely available graphics software and the result is also included in this work.

This diploma thesis is focused on use of measuring interface myDAQ by National Instruments company in teaching of electrotechnical measurement at vocational school. The aim of this work is the design of set of suitable measuring tasks covering the curriculum in electrotechnical measurements for the 3rd and 4th class of study branch of 26 41 M/01 Electrotechnics. Description of the properties of the measuring interface myDAQ and the respective utility programme National Instruments Multisim is a part of this work. The practical part contains technological and photographic documentation of the various products that can be connected to the interface myDAQ. This thesis is built on the author's bachelor thesis.

In accordance with its title, this Thesis Aims to Analyse Legal Aspects of Climate protection. Therefore its structure comprises of Five major sections dedicated to offer substantial amounts of information on the topic of Climate Change and its Protection. The first section describes the Issue of Climate Change, the History of its Protection as well as necessary measures and certain difficulties to achieve a consensus usually occurring during international negotiations. The second, third, and forth sections address Legal Climate Protection at International, European Union, and National Levels. Finally, the closing fifth section not only summarizes all that has been stated in previous sections but also evaluates Efficiency of actions taken at the three levels mentioned. Furthermore, the last section suggests where the major efforts should be focused on in the forthcoming years. All in all, the main objective of all the sections introduced is to Highlight the Urgent Need for Effective and Coordinated Action taken by the Whole International Community based on Conscious and Mindful Doings of each and every Individual. This requirement is the very crucial precondition in order to keep the global rising temperature below 2 degrees celsius by the end of the 21st Century so that potential negative and...
