Determining motion using accelerometer data
Montilla, Michaela ; Koťová, Markéta (referee) ; Janoušek, Oto (advisor)
The aim of this thesis is to present the topic of acceleration record using accelerometer sensors and to create a program for the transformation of the acceleration data into the position vector. It is a summary of theoretical background of data recording using sensors of acceleration and an overview of the physical relationships between acceleration, velocity and position. The data was recorded by multiple types of sensors. The gist of the algorithm is a mathematical realization of physical relations modifying the conversion of acceleration to the position. The outcome enables to display a dynamic graphic output in 3-D.

Back-End Design for Analytical Dashboard of Positioning System
Hrivňák, Marek ; Bardonek, Petr (referee) ; Šimek, Václav (advisor)
This thesis deals with the optimization of the original solution and the design of a new solution for the storage and processing of positional data for the tool Sage Analytics of RTLS developed by Sewio Networks s.r.o. The objective of this study is to find and implement a solution to reduce the production time of Sage Analytics metrics. The optimized original solution provides in a very simple way (without the need to modify the implementation) significant acceleration in the production of metrics (for a time interval of 24 hours of displayed data) on average by up to 503 %. The proposed solution uses the InfluxDB database to store positional data and modifies the data processing in such a way, that it is compatible with the use of a new method of storing and retrieving positional data. The new solution also includes tests to check the correctness of the proposed solution. The application of this solution brings acceleration in the production of metrics (for the time interval of 24 hours of displayed data) from 725 % up to 2085 % and on average up to about 1010 %. Part of the work is also the performance of several experiments, which aim to reveal the reasons for the duration of metrics in Sage Analytics.
