This diploma thesis deals with possibility of using a mobile phone to measure vehicle dynamics and determine the accuracy of this measurement. In the research part, it is first mentioned what methods are used to produce sensors for mobile phones. Next, a description of individual sensors that can be used for vehicle dynamics measurement, the principle by which the sensors record measured values and their inaccuracies. The practical part shows with which professional device the accuracy of the mobile phone is compared, how data can be collected from both devices and how the comparison measurement was performed. This section also describes the ways in which the measured data of the mobile phone can be improve for better accuracy, and finally the comparison of the measured values from both devices from different points of view.

Dynamic Li-ion battery model
Loucký, Vojtěch ; Cipín, Radoslav (referee) ; Toman, Marek (advisor)
The main aim of this work is to compare mathematical models of Li-Ion batteries and for the chosen mathematical model create dynamic model in MATLAB. Different mathematical models are compared based on their weakness. There is detailed description of Improved Thevenin model, which is then created in Simulink and is tested for various discharging currents. This model is adjusted to work with parameters obtained from measuring data on real Li-ion cell and the results from simulations are compared with results from real measurements.

Software Package for Ultrasound Perfusion Imaging
Mézl, M. ; Jiřík, Radovan
In this work a Matlab-based software package for perfusion imaging is presented. It is run with a graphical user interface (GUI) and includes five main steps of perfusion analysis. There are applications for data import, image registration, tissue selection, perfusion analysis and visualization. This software has been used for analysis of abdominal ultrasound sequences. It is modular and each module can be easily modified for various methods as well as different image modalities for example magnetic resonance imaging.
