Delta 3D Printer Construction With 32-Bit Electronics
Němec, Radek
This paper deals with the construction of delta 3D printer, including all necessary peripherals. Paper mentions benefits of delta 3D printers in comparison with the most common cartesian type of 3D printers. The main part of this paper is about created 3D model of delta 3D printer with all its components which includes 32-bit electronics controlling board used for this printer.

Detection of pathologies in ECG signals
Němec, Radek ; Mézl, Martin (referee) ; Kašpar, Jakub (advisor)
This thesis attempts with methods for detection of pathologies in ECG signals. The first part is focused on the basic theory of heart anatomy, electrocardiography and individual heart pathologies. The second part describes the preprocessing of ECG signals, detection of QRS complexes and detection of individual pathologies. In the third part the detector is being tested on CSE database and my own measured data.

Delta type of 3D printer
Němec, Radek ; Jaššo, Kamil (referee) ; Vyroubal, Petr (advisor)
This master thesis is about design and construction of FDM delta 3D printer which consists of 32-bit electronics, magnetics printer head and other necessary peripheries. Opening chapters of this thesis are about theory of 3D printing and its methods with description of FDM 3D printers and summarization of FDM plastic materials used for 3D printing. The next part is about used electronics and problematic of heat transfer. The main part of this thesis describes design and construction of 3D printer and its necessary peripheries, which includes creation of its 3D model and application for 32bit controller. 3D model of delta 3D printer and its heating components was created in CAD software SolidWorks. The last part includes description of commissioning and calibration of delta 3D printer with summarization of economic aspects of its creation.

The Castor Bean Tick (Ixodes ricinus) in Education
Němec, Radek ; Říhová, Dagmar (advisor) ; Hanel, Lubomír (referee)
The aim of this work is to point out the interconnectedness of human life with parasitic organisms, especially with the Castor bean tick (Ixodes ricinus). This tick forms an integral part of our rich invertebrate fauna and has become an increasingly frequent interest of media in the last few decades. This thesis attempts to bring closer the relationship between tick and man from different perspectives, and to reveal essence as well as pitfalls of tick life. For many people, this arthropod represents an insurmountable resource of aversion and fear. Hence, an integral part of the thesis is the introduction of prevention methods and treatment of parasitic diseases transmitted by the tick, as well as monitoring of new trends in the therapy and development of vaccines. Also, the text offers a proposal how to bring the tick closer to the pupils in teaching Biology. KEYWORDS The Castor bean tick, parasite-host relationship, life cycle, encephalitis, borreliosis, collection methods

Cooling of Two-channel audio power-amplifier using FVM
Němec, Radek ; Kazelle, Jiří (referee) ; Vyroubal, Petr (advisor)
This bachelor´s thesis is dealing with the design and construction of two-channel audio Leach type power-amplifier, including the necessary additional components and subsequent design of the amplifier cooling using Flow Simulation tool included in the SolidWorks design system. The opening chapters is about theoretical analysis of audio amplifiers, heat transfer and description of SolidWorks design system. The main part of this thesis contains the design and construction of amplifier and design of each variants of amplifier cooling, including the best variation designed. The last part of the thesis is about assembling the amplifier and evaluation of economic aspects of its production.

Development of a mobile application for Windows Phone and its publication in the Windows Phone Store
NĚMEC, Radek
This thesis describes the mobile operating system Windows Phone 8.1 (launched in the middle of 2014) and an application development. A partial goal is to introduce the system, including all parameters, features and technologies, which are necessary for application development. The main goal of my work is to create an application that downloads exchange rates of selected currencies from the website of the Czech National Bank. The app shows current exchange rates. It is possible to convert between different currencies. Also, there is a graph of the selected currency showing exchange rate history in selected period. My app is fully customizable for every user, so they can adjust it to suit their needs. In my thesis there is a summarization of all the information necessary for introducing Windows Phone 8.1 to the beginners in application development.
