Electrooculogram based text comprehensibility evaluation
Netopil, Jan ; Čmiel, Vratislav (referee) ; Janoušek, Oto (advisor)
This thesis deals with principles and measuring of electrooculography (EOG) and with electrooculography signal utilization for assessment of reading comprehension. The basic physiology and anatomy of the eye, types of eye movement and identifiable elements in EOG during reading are described in thesis. Methodology of electrooculogram-based text comprehensibility evaluation is described and verified by recording of EOG of ten volunteers using Biopac system. Detection of identifiable elements is implemented by Matlab. The last steps of process are statistical evaluation of data and revers identification of text complexity.

Tractor Shift Mechanism Analysis
Netopil, Jan ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
The thesis focuses on the shifting mechanisms of manually shifted tractor transmissions. It provides a comprehensive overview of all significant structural nodes of the shift mechanism with an analysis of the influence of the structure on the resulting intensity of a force required for shifting. The main aim of this thesis is the design and validation of experimental equipment for measuring the force effects of the shift mechanism of a mass-produced tractor in actual operation. The design of the experimental equipment is based on a study of the used measuring technique and similar experimental equipment. The final structure is selected based on selection by the method of weighted values, taking into consideration the requirements of the structure. A functional measuring chain is designed and formed for the realization of the measurement. To evaluate the data from the technical experiment, a multibody model of the designed experimental device is created in the MSC Adams View software, through which the real parameters of the shift mechanism are obtained from the measured values. The designed experimental equipment brings the possibility of complete analysis and subsequent optimization of the tractor's shift mechanism

Škoda Octavia Super
Netopil, Jan ; Nedoma, Jiří (referee) ; Kaplan, Zdeněk (advisor)
My work contains a comprehensive aggregate of knowledge which is needed for a renovation of a car Skoda Octavia Super. It provides a description of the construction and an execution of a chassis, a transmission, an engine and accessories of the car for individual manufacturing sets, next is a description of a colour execution and a superficial modification. I put emphasis on the identification of all mechanisms and Skoda Octavias accessories (the eighth manufacturing set). The right execution approximates many photographs, a function of the transmission of a functional scheme. All mentioned pieces of knowledge are based on studying of a period literature, a catalogue of spare parts, a contemporary literature and verifying information in the Skoda Octavias museum and in veterans clubs. This work also pays attention to issues of the renovation of the car and its financial demands, options how to use additive technologies during the renovations of cars. In conclusion is evaluated a condition of renovated Octavia Super, year of production 1960, carried out a checking measuring of selected mechanisms and worked out a budget of the renovation. The work brings theoretical knowledge which is needed for returning of the car, Octavia Super, to the state as it was made.

Optical methods of gesture recognition
Netopil, Jan ; Odstrčilík, Jan (referee) ; Čmiel, Vratislav (advisor)
This thesis deals with optical devices and methods image processing for recognizing hand gestures. The types of gestures, possible applications, contact based devices and vision based devices are described in thesis. Next, a review of hand detection, features extraction and gesture classification is provided. Proposed gesture recognition system consists of infrared camera FLIR A655sc, infrared FLIR Lepton module, webcam Logitech S7500, method for hand gesture analysis and a database of gestures for classification. For each of the devices, gesture recognition is evaluated in terms of speed and accuracy in different environments. The proposed method was implemented in MATLAB.
