Mobile Application for Learning to Play Drums
Novotný, Jan ; Zemčík, Pavel (referee) ; Beran, Vítězslav (advisor)
This bachelor thesis aims to design and create a mobile application for teaching percussion playing and rhythmic reading training. The application contains several lessons with exercises that are displayed in the form of music notation. It is made possible to play and practice individual exercises accompanied by a metronome. Furthermore, it offers an analysis of the play on the instrument and provides feedback on the quality of playing. The application is developed on the Xamarin platform for use on Android and iOS operating systems. The result of this work is an application that will serve drummers to practice and provide an evaluation of the accuracy of the played exercise and thus will help to improve their playing skills.

Meteorological station system
Čada, Jan ; Balík, Miroslav (referee) ; Lattenberg, Ivo (advisor)
This bachelor thesis deals with the design and implementation of a online meteorological station system, which consists of individual weather stations that communicate via the Internet with the server. The first part of the thesis discusses the principles of measuring major meteorological variables and deals with the selection of suitable sensors for measuring temperature, atmospheric pressure, humidity, wind speed and rainfall. In the practical part, one of the weather stations based on Raspberry Pi Zero microcomputer is designed and realized. As a complement to the measured data, the station includes a camera that captures the view from the site where the meteostation is installed. 3D printing is used to realize most of the mechanical parts, it has the advantage of speed, accuracy and easy reproducibility. For the measurement of temperature, pressure and humidity, a combined sensor BME280 from Bosch is used, which is placed in a small Stevenson screen. The wind speed is measured by a cup anemometer whose rotation is sensed by an integrated Hall sensor. The output pulses are then counted using the PCF8583 circuit, which has an I2C interface for reading the values with a Raspberry Pi microcomputer. Special attention is paid to the construction of a custom calibratable tipping bucket rain gauge with a resolution of 0,5 mm, whose mechanical motion is also sensed by a Hall sensor as in the anemometer. The reading of the data from sensors and sending it to the server is handled by a Python script. For storing and presenting data to users, a custom server solution based on LAMP webserver is implemented, its source codes are written in PHP, HTML, JavaScript and CSS. In addition to the web interface, which displays the data in graphs, the measured data can be also presented to the user via an application for mobile devices based on Android. The application was developed in C# using the Xamarin framework in the Microsoft Visual Studio development environment. Among other things, it implements a widget for quick access to the measured values directly from the home screen. In the final part of the thesis, interesting findings obtained by observing the measured values are mentioned.

Mobile Application Supporting Management of Traffic Constructions
Obořil, Radek ; Španěl, Michal (referee) ; Herout, Adam (advisor)
This thesis deals with development of an application supporting management of traffic constructions. The resulting solution consists of a mobile application and a server application. The mobile application allows users to document progress of a construction using integrated camera, maps and GPS, and send collected data to the server. The server application includes a web service for client-server communication, and a web application for database management and processing of the collected data. Apart from the design and implementation, the features and technologies of mobile devices utilized by the application are discussed. The thesis also reviews current most significant mobile platforms and analyses concepts and technologies of cross-platform development, especially Xamarin and MvvmCross, which were used for development of the above-mentioned application.

Mobile App for Shooting New Photos of Ancient Postcards
Buchta, Martin ; Zemčík, Pavel (referee) ; Herout, Adam (advisor)
The aim of this thesis is to create a mobile application which allows to capture actual photographs of ancient postcards. Application is implemented for Android operation system. Theoretical foundations about problematics of repeat photography and used technologies are described in this thesis. Practical part of this thesis describes design, implementation and testing of the application. Xamarin integrated development environment which is based on programming language C# was utilized for practical part of thesis. Final application allows user to capture the most accurate photography corresponding to historical postcard.

A Tool for Transformation of e-Shops into Mobile Devices
Vídeňský, Zdeněk ; Loukota, Petr (referee) ; Bartík, Vladimír (advisor)
This bachelor thesis is focused on transformation of data from e-shops into the mobile application. My goal is to create a complex system for creating the native mobile app for existing e-shop based on the data from a user. The system consists of server-side and a client-side applications. On the server there is a running web app written in the ASP .NET framework, which cares of the processing data entered by a user and of filling database by products and categories on the base of provided XML feed. The server-side application also provides the web API for communication with a client. The client is a native mobile application running on Xamarin platform. This application is written multiplatformly with Xamarin.Forms, the result of this tesis is the only application for Android system. With this application the user is able to browse products and create the orders which are stored on server.

Mobile Game for Practicing English Vocabulary
Hubík, Antonín ; Kanich, Ondřej (referee) ; Dyk, Tomáš (advisor)
Cílem této práce bylo navrhnout a implementovat multiplatformní vzdělávací mobilní hru pro procvičování a rozšiřování anglické slovní zásoby. Hra je založena na pravidlech slovní kopané a jí podobných her se slovy a obsahuje režim online hry dvou hráčů proti sobě. Aplikace využívá platformu .NET, kde je implementována v jazycích C# a XAML. Činnost mobilního klienta závisí na vzdálených službách, které byly nasazeny s využitím vhodných cloudových služeb a integračních možností platformy Microsoft Azure. Verze mobilní aplikace pro Android byla publikována prostřednictvím Google Play v režimu přístupu pro testování a ozkoušena na uzavřené skupině uživatelů s vlastními zařízeními. Na základě zpětné vazby z testování byly navrženy možnosti dodatečných vylepšení v oblastech odstranění technických slabin a přidání nových funkcionalit.

Intelligent Recognition of the Smartphone User's Activity
Pustka, Michal ; Goldmann, Tomáš (referee) ; Drahanský, Martin (advisor)
This thesis deals with real-time human activity recognition (eg, running, walking, driving, etc.) using sensors which are available on current mobile devices. The final product of this thesis consists of multiple parts. First, an application for collecting sensor data from mobile devices. Followed by a tool for preprocessing of collected data and creation of a data set. The main part of the thesis is the design of convolutional neural network for activity classification and subsequent use of this network in an Android mobile application. The combination of previous parts creates a comprehensive framework for detection of user activities. Finally, some interesting experiments were made and evaluated (eg, the influence of specific sensors on detection precision).

Mobile Application to Control the Diet of Patients on Dialysis
Pavlacký, Ondřej ; Kolář, Dušan (referee) ; Goldmann, Tomáš (advisor)
The goal of this thesis is to create an intuitive mobile application for Android operation system which will help dialysis patients by displaying approximate values of monitored substances in their body and replace classic paper records. Thanks to this mobile application patients are going to have better overview of consumed foodstuffs a help them stick to their diet. When inserting the foodstuff patients will select from the database of foodstuffs and the application will calculate values that the food contains. Patients can also expand the database with their own food. Application will also register periods between dialysis and from the length of the period, patients' weight and their diuresis calculate maximal values of monitored substances (water, potassium and phosphorus). Patients will also see values from passed periods, which will we shown in statistics. Data will be persistently saved in local and remote database. Application is developed on Xamarin platform.
