2D ultrasonic positioning
Junek, Jiří ; Šťastný, Ladislav (referee) ; Hynčica, Ondřej (advisor)
This thesis deals with the implementation and evaluation of measuring directional and omni-directional ultrasonic senzors. Control of ultrasonic senzors and computation of a distance is realized by using a microrontroller Arduino Duemilanove. The first part deals with the measurement of directional sensors, their wiring and subsequent processing of the measurement is performed in Matlab. The second part deals with solving of measuring and visualization 2D position omni-directional ultrasonic senzors, implementation trilateration algorithm for calculating x and y coordinates and comparison the used filters. At the end of this thesis also includes a comparison of directional and omni-directional ultrasound and evaluate their applicability for measuring 2D position.
Modeling of Dynamics of the Part of a Printing Machine
Junek, Jiří ; Šolc, František (referee) ; Václavek, Pavel (advisor)
This thesis deals with modeling dynamics of printing machine, made by SOMA Engineering, in toolbox SimScape of simulation program Simulink/Matlab. There are descibed properties, progress, important principles and laws of modeling in this toolbox. The first part is focused on creating models, which consist as mechanical as eletrical and control parts. In the second part is explained how to create user interface to control models and creating standalone application, executable without installation of Matlab or Simulink. In last part is explained principle of identification parameters of material from the measured data, using an optimalization algorithm Nelder-Mead. Created models and identification algorithm are controlled via user interface.
Tourism in Soci
Harakhavik, Aksana ; Jarolímková, Liběna (advisor) ; Junek, Jiří (referee)
Russia has great potential for tourism development. However, these options have been used recently in a completely inadequate manner. The main causes are socio-economic crisis and lack of infrastructure development, tourism in Russia
