Software for processing data from the accelerometer
Zahradník, David ; Vetiška, Jan (referee) ; Kovář, Jiří (advisor)
This thesis deals with the creation of software for statistical processing of data from the accelerometer. In the first part are specify the objectives. The next part of the thesis is followed by design and creation software for statistical processing of data in real-time as well as post-processing mod. Final program is tested by using stored data from the accelerometer. At the end the functionality of the created software is evaluated. This program is created by using the programming language C #.

Multifunction data acquisition, measurement and control device
Trávníček, Ivo ; Vlachý, David (referee) ; Grepl, Robert (advisor)
The thesis deals with and tests the Multifunction data acquisition, measurement and control device. The unit is based on the microcontroller ATmega, which was programmed in the language C. The unit contains functions for the measurement of physical quantify, filtering record, regulation of the dynamic systems and communication with PC. Configuration of the unit is real-time in special software created in the language Matlab or by a terminal. The purpose of the unit is controlling a DC motor by the PID regulator, long-term measurement of temperature or measurement of acceleration by an accelerometer.

Data glove: VRML visualization and design of electronic circuits
Štěpánek, Jan ; Bezdíček, Milan (referee) ; Grepl, Robert (advisor)
This work deals with designing and assembly of electronics of a data glove and creation of a hand visualization which projects a real-time state of user’s hand. Realization was a team effort of two students. The division of tasks is described in the chapter called Stanovení cílů práce. The beginning of the work is dedicated to a background research in the field of data gloves. Next chapters describe creation of the model of virtual hand. This model‘s task is to project real-time state of user’s hand based on data received from the flexure sensors and MEMS accelerometer. Communication with PC is realized through BlueTooth serial port virtualization. Mathematical model created in Matlab processes data received from the glove and calculates the values of the positions of the individual parts of hand. Matlab also served for development of a graphical user interface which enables the user to utilize the glove.

Non-traditional traffic engineering measurment methods
Martínek, Jakub ; Holcner, Petr (advisor)
This thesis aims to researching usage of IMU (Inertial Measurement Unit) in traffic engineering. First part focuses on description, production and general usage of IMUs. Second part of the thesis describes possible usage of IMUs in traffic engineering: a) Evaluation of parameters and condition of roads b) Impact of parameters of roads on vehicle and people Main focus of the third part is on processing, achieving and evaluating data of experimental measurements, I have done personally. Those are: • settlement of IMU • starting the vehicle • direct drive • slanting slope from a residential zone • long speed bump

Analýza stability kořenového systému intaktních a uměle poškozených stromů za využití přístrojových metod šetření
Šponarová, Klára
This thesis focuses on the root system stability analysis and it deals with the dynamic stress caused by wind. The subject of focus is testing intact and artificially damaged trees with the help of accelerometers which might be used in the field of arboriculture to evaluate the tree resilience to being blown down. Thesis analyses this method by administering the test and evaluating the resulting data. This thesis also proposes different options for using the new information while contemplating the problem of tree resilience to dynamic stress.
