Development of an Amazon Alexa Skill for Amazon Echo
Dobrík, Andrej ; Zeman, Kryštof (referee) ; Pokorný, Jiří (advisor)
V posledných rokoch nastala významná zmena v spôsobe interakcie medzi používateľmi a inteligentnými zariadeniami. Pre ludí je najpraktickejší spôsob interakcie s týmito zariadeniami hlasová interakcia. Veľa firiem si túto zmenu v interakcií uvedomilo a začalo vytvárať software a príslušný hardware pre tento spôsob interakcie. Táto bakalárska práca sa bude venovať týmto produktom, konkrétne produktom Amazon Echo, ich schopnostiam a požiadavkam. Nasledujúc vysvetlením komunikácie Echa. Priblížením Amazon Alexa Skills Kit a vytvorením a implementáciou nového vlastného Amazon Alexa Skillu pre Amazon Echo.

Automatic Dosing Unit for Pool Chemistry
Kejík, Jan ; Štůsek, Martin (referee) ; Zeman, Kryštof (advisor)
The objective of this thesis was to design and construct the dosing unit for pool chemistry with the features of common available equipments, but with lower acquisition costs compared to these equipments. The initial part of this thesis describes the requirements for water quality in the pools and the principles of its sustaining. The next section describes the ESP32 microcontroller, which was selected because of sufficient computation power and memory resources and RF connectivity capability. Furthermore, the pH, ORP probes and temperature sensors for measurement of the pool water quality are described in this section. Lastly, sensor convertors, power supplies, pump controls circuit and display interface are described here. The key section of the thesis is the design description which consists of hardware, mechanical and software section. It starts by the description of the printed circuit board with a description of diagram. In the section followed is described and illustrated mechanical design of the box for this dosing equipment. It is my own design made by 3D print. The last design section deals with software consisting of three different kinds of software: display software, ESP32 microcontroller firmware written in C/C++ and HTML code of the webside. This description is focused especially on the firmware architecture of the processor ESP32 related to consecutive part including description of a local user interface as well as a web application. The resulting device was developed to the state with matured well tested user interfaces. However, the controls algorithms of pH and ORP were tested only in simulated conditions. Therefore the testing in real pool for verification of the firmware and reliability should be done in the next steps.

Utilization of Android Wear Platform for Voice-control Services in Smart Home
Frolich, Libor ; Zeman, Kryštof (referee) ; Hošek, Jiří (advisor)
The bachelor thesis deals with the connection of smart homes and voice-controlled assistants. There are described used devices: Huawei Watch 2, Raspberry Pi 3B+, TP Link LB130 smart lightbulb and Intertechno ITR-1500 wireless sockets. Linking has been achieved through the Actions SDK, combined with a smart Google assistant. The problem was implemented by connecting a simulated home and designing a server application. The server was running on the Raspberry Pi computer using the Node.js. At the end of the thesis was solved the problem of processing voice commands and updating of the operating system of smart watches.

Model-View-ViewModel design pattern in WPF applications
Švikruha, Patrik ; Zeman, Kryštof (referee) ; Lattenberg, Ivo (advisor)
The thesis deals with the explanation of the proposal application according to multi-layered presentation models which describe the distribution of the application layers thereby its facilitating, testability, sustainability and transferability. In this work i focus myself on presentating model for Model-View-ViewModel which is primary designated for WPF application. This presentating model is possible to be built by frameworks used as NuGet open-source package managers or Project templates. In this thesis I focus on framework Catel, which can be used thanks to it´s robustness through all layers of application. The primary output of this thesis is a real application, on which I demonstrate design template with the intagration of framework Catel. I tried to describe whole theory and following process as easy as possible, that even an reader, who has no experiences with designing a multilayer application, could understand it.

Impact of aerial platform material on antenna gain
Tobolka, Lukáš ; Zeman, Kryštof (referee) ; Pokorný, Jiří (advisor)
The goal of this thesis is to recreate some of the most used multicopter configurations within CAD software with varying materials. These models are then imported into ANSYS HFSS to examine the influence of shape and material on the performance of an antenna. Results from these tests could help in the creation of a high-speed (Gb/s) backhaul network in the future. The theory section is about multicopters, their configurations and materials used in their manufacture. Subsequently, it delves into the fundamental theory behind antennas and the description of CAD software (Autodesk Inventor 2016) and antenna simulation software (ANSYS HFSS). The practical section includes: description of the measurement process for the MikroTik wAP 60G AP antenna, the parameters of which were used during the simulation; a model of the antenna (horn) and last but not least the results of the measurements, which are the thesis’ main benefit.
