Scala Programming Language and Its Use for Data Analysis
Kohout, Tomáš ; Bartík, Vladimír (referee) ; Zendulka, Jaroslav (advisor)
This thesis deals with comparing the Scala programming language with other commonly used languages for data analysis. These languages are evaluated on the basis of the following categories: data manipulation and visualization, machine learning and concurent processing capabilities. The evaluation then shows the strengths and weaknesses of Scala. The strengths will be demonstrated on application for email categorization.

Web Visualization of Smart Devices Data in IoT
John, Petr ; Burget, Radek (referee) ; Hynek, Jiří (advisor)
Due to the constant growth in the count of smart devices the need to store, aggregate and process the data effectively rises. The gathered data needs to be displayed effectively to the user, who will be able to react to the current state of the monitored device. This master's thesis deals with storing the data and displaying them using dashboards. The goal of this thesis was the creation of a library composed of components intended for data visualization and a simple API application, that can store and query the data effectively. The library is introduced in a simple application that uses the API application. Some parts of this solution are currently used in the company Logimic, where the costs of the database system reduced to 15 % of the average cost of the previous database system in the last 2 months. The rest of the solution is currently being integrated into the existing systems of the company.

Microprocessor Controlled Power Measurement System for Frequencies below 10GHz
Klíma, Martin ; Lukeš, Zbyněk (referee) ; Urbanec, Tomáš (advisor)
The aim of this work is to design a microprocessor controlled power measurement system which is based on the logarithmic detector AD8317, then to create a printed circuit board and to test its functioning. The logarithmic detector AD8317 is acceptable for measurement of high frequency signal’s power of the level between approx. –55 dBm and – 3 dBm in the frequency bandwidth of 1 MHz to 10 GHz. Its output provides DC voltage which is corresponding to the decibel-scaled level of the input signal. This is suitable for A/D conversion and digital processing by the microprocessor. The result of the work is a complete measurement system.

Database Archive of Medical Image Data
Lerch, Kamil ; Přibyl, Bronislav (referee) ; Kršek, Přemysl (advisor)
The work deals with the management and display of medical images. Analyzes the problem of obtaining information from medical DICOM and efficient storage. The system is designed as an application with a graphical client. Provides an interface for importing data in a format DICOM and interface for retrieval of data in the database and display them. The implementation was done in Java with support for SQLite.
