Genetic Algorithms used as Control System of an Autonomous Vehicle

Jiří Kacer, Robert Kotzian

Abstract


The common method used to gain fault tolerance is to include a redundancy to the system. As an alternative to this form, we chose in this paper involvement of fault tolerance directly to the system fundamental, without using the redundancy.

Biological-psychic pilot’s state model of the pilot and behavior pilot’s model

Jindřich Janíček

Abstract


Demands on the quality of weapons systems are extremely high today. Technical majority in weapons systems plays very important task in battle-conflicts. We could it see in conflicts in Yugoslavia, Afghanistan, and first of all in Iraq. Consequently it is necessary to make modernization of battle technique and create weapons systems, which use newest knowledge in science. There are two principles for modernizing of weapons systems today.
The first principle is an old weapons system substitute with new technique, but it is very expensive always. The second principle is: modernize weapons systems in cases, when it is possible it to make and when it is advantageous financially.

Adaptive Cockpit Multi-agent Systems

Martina Gabrielová, Kateřina Holá

Abstract


Multi-agent systems are today, as element of the distributed artificial intelligence, an important and prolific area of research and development. In artificial intelligence research, agent-based systems technology has been hailed as a new paradigm for conceptualizing, designing, and implementing software systems. Multi-agent technologies can solve problems by using decomposition of a complicated system to simple subsystems. We can use multi-agent technology to the simulation of the cockpit system and identification of the states.

Modelling Of Dynamic Features Of The Vertical Gyros

Jan Čižmár

Abstract


The article deals with accuracy of the attitude measurement by means of vertical gyros or artificial horizons using the gyros with three degrees of freedom. More specifically, the instrumental accuracy is analyzed for which the so called remanent angles are characteristic: they are given by both the factor of friction in the bearings of the Cardan’s suspension, and amplification of the correction device.

Accuracy Of Aircraft Barometric Altimeters

Jan Čižmár, Miloš Andrle

Abstract


The article deals with methodical and instrumental errors of the aircraft barometric measurement of the flight altitude by means of mechanical altimeters and air data computers. The calculation of the methodical errors has been carried out both for selected values of the declension from the standard values, and for three real meteorological situations on the base of which the methodical accuracy of the barometrical altimeter and the air data computer has been compared.

Hightorque stepper machine and its 3-D model in ANSYS

Dušan Maga, Vladimír Řeřucha, Ján Halgoš

Abstract


This paper deals with hightorque stepper machine – Megatorque problems. Basic characteristics and parameters of given electrical machine are described in this paper. Following its parameters 3-D model was created. We have used program ANSYS in creating 3-D model and analysis of magnetic field in hightorque stepper machine. The program is working on Final Elements Method principles. For better solution we have designed only a part of the model by one sixth due to the machine’s symmetry. In the article are introduced ways hot to describe results of magnetic field distribution.

Using of Canny Filter For Image Correspondence Finding

Petr Stružka, Miroslav Uher

Abstract


The paper describes an application of the Canny edge detector in the process of image correspondence finding, which is used as a one method of the 3D reconstruction from the set of stereo images. The used Canny filter leads in algorithm speeds up and in better performance of vectorization process.

Manipulator Kinematics Solving by the Matrix Method

Jiří Fischer, Jiří Kacer

Abstract


Beside the design of the industrial robots and manipulators is always needed to get patterns of the designed mechanism movement. These problems solve the kinematics analysis, which result is the determination of the movement, velocity and acceleration equations of the significant points in the construction of the manipulator. In this paper is the problem of computation of the kinematics values of the simple manipulator with two degrees of freedom outlined.
