Kombinovaná výroba tepla a bioplynu pomocí bioreaktoru / Combined heat and biogas production using a bioreactor

Novák, David January 2018 (has links)
This diploma thesis deals with the bioreactor system and its use for the production of heat and biogas. The bioreactor uses the composting and metanogation process of fermentation that humanity has known for hundreds of years, but the combination of these processes is a relatively unexplored area. The theoretical part of the thesis analyzes the existing possibilities of utilization of the heat generated in the compost, and also describes the used technology of small biogas stations and other small systems for biogas production. It follows the practical part of the work, when it was the task to design a bioreactor working at low temperatures during the winter. Part of the solution is the initial design and testing of the basic test structure of the bioreactor, followed by the implementation of a more advanced and more complex system, including a control and measuring center realized by a microcontroller.

Zpracování signálu SDR pro přenosnou monitorovací stanici / SDR Signal Processing for Portable Monitoring Station

Svobodník, Petr January 2018 (has links)
Goal of this thesis is to develop portable monitoring station for radio spectrum monitoring and its controlling application for use by Czech Telecommunication Office. The station is based on Software Defined Radio (SDR) and capable of monitoring in the range of 1 MHz - 6 GHz. Developed application controls not only the SDR but also the external RF unit (including choice of receiving antenna, filter, optional amplification/attenuation and azimuth of antenna rotator). Measurement processed by computer and displayed graphically in form of spectrum diagram and waterfall diagram. Furthermore, the application will perform spectral measurement in compliance with requirements of International Telecommunication Union. The application is also capable of recording into the file and of analyzing historical data from the previous measurement.

Optimalizace návrhu čerpací stanice / Pump station design optimization

Kunovský, Lukáš January 2018 (has links)
This diploma thesis summarizes the necessary knowledge for the design of the pump station. It focuses on the choice of suitable pumps and control valves. It also provides information on mathematical optimization methods. By combining these two disciplines a program was created that selects the most suitable combination of pumps and valves for the assigned requirements. These can vary over time. The goal of optimization is to minimize initial and operating costs. The phenomena considered are: time-varying flow and head height, serial and parallel co-operation of pumps, throttling control, a change of characteristics for variable speed and temperature, suction height control, maximum motor output, loss in connection piping.

Návrh a implementace autonomního dokování mobilního robotu / Development of mobile robot autonomous docking

Čepl, Miroslav January 2019 (has links)
This thesis implements solution for automatic docking for a mobile robot using visual markers. After initial survey of already implemented works, new docking solution is proposed. Feasibility of the solution is verified with tests of marker detection precision. The implementation is tested in a simulation and with a real robot. The functionality of the proposed solution is verified by long-term tests. The result of this work is robot’s ability to navigate known environment to find and dock a charging station. After charging the robot is able to safely disconnect from the station.

Studie rekonstrukce plynovodní sítě vybrané části urbanizovaného celku / Study of the reconstruction of the gas pipeline network of a selected part of the urbanized unit

Tamborlani, Alessandro January 2021 (has links)
The diploma thesis deals with the study of construction and reconstruction of gas pipeline networks. It will acquaint us with the basic properties of gases, from their extraction to distribution. At the end of the work we apply this knowledge to the real situation of construction of the regulation station together with the reconstruction of the adjacent gas pipeline network in Tišnov with the application of the 3D program Revit.

Rekonstrukce transformační stanice 110/22 kV / 110/22 kV Transforming Substation Reconstruction

Kubiš, Petr January 2008 (has links)
This thesis deals with the issue of reconstruction 110/22kV distribution substation in economic point of view, where we will assess the benefits of a combination of their involvement using the discounted cost. It’s necessary to reconstruct distribution substation due to the increasing demand for electricity, upgrading equipment in the distribution systems, improve the reliability of electricity supply to customers, etc.. Distribution substation layout must meet conditions resulting from a law on energetics and operation of primary distribution networks.

Bezdrátová meteostanice / Wireless meteostation

Holain, Martin January 2011 (has links)
The objective of this thesis is a design of the amateurish wireless weather station which is used to measure temperature, relative humidity, barometric pressure and velocity and direction of air flow. Part of this thesis also describes design of a device intended for display, processing and storage of actual measured data obtained from weather station.
