CAN Messages Transmission Diagnostic Analysis of Avionic System

Jiří PAŘÍZEK, Přemysl JANŮ

Abstract


Digital communication bus Controller Area Network (CAN) that was originally designed for the automotive industry considering its excellent features has become to apply in the aerospace industry. In general one of the requested properties of the aerospace products is
high dependability and maintainability. The paper summarizes CAN diagnostic equipment, which enables to detect, locate and indicate errors and failures and provide characteristics required for the airborne applications. Further the paper analyses transmission CAN
messages behavior of an aircraft electronic system consisting of several modules based on the time-triggered communication mode of the CAN with CANaerospace protocol.

Experimental Parameters Identification of the Human-Pilot Model Behaviour

Rudolf JALOVECKÝ, Přemysl JANŮ, Jan BOŘIL

Abstract


The paper represents one of the other ways how to optimize alternative mathematical human-pilot model usable in the models of the aircraft flight control in the space. In general, the creation of the equivalent human model is very complicated, because the human characteristics are not constant in the time. The characteristics are changing with immediate human ability. At the simulation of the human behaviour is possible to compile only general, an approximate human model. The contribution shows further possibilities how to explore the human-pilot behaviour during the determining of chosen transfer functions parameters.

Offline Parameter Identification - The Random Initial Estimation Issue

Michal DUB

Abstract


Experimental offline identification algorithm is based on minimization of criteria function considering the unknown mathematical model variables. We often use software support of various computing programs to find the minimum of a scalar function of several variables. However, operator has to know initial estimation of the searched parameters to get proper results. If operator sets bad initial estimation, the identification process would find another local minimum or would diverge. This paper is focused on random approach to initial estimation of simple mathematical model using basic MATLAB software support.

Concept Development and Experimentation in STRUCTURE Project

Vitezslav JAROS

Abstract


The creation of the concept is a process stemming from the transformational changes as well as capabilities development. At the onset, the questions and new ideas dealing with capabilities requirements emerged. In the end, the approved concept is implemented into areas influenced by this new approach. The author explains various possibilities for using the CD&E method while working on projects in the armed forces and proposes its application procedure in the defence project STRUCTURE.

The Analysis of the Security of the Organization

Oldřich LUŇÁČEK

Abstract


This article is focused on the area of the security. In security area is very important to know all possible threats, project countermeasures in all contexts. The organization must use very effective tool for effective management of the information security. The current practise is based on the empiric finding of the personnel who manage security. The article describes possible method for the integrated control of the security. In the final part of the article is a proposal of the methodology.

Selected IPv6 Security Aspects

Josef KADERKA

Abstract


Internet Protocol version 6 (IPv6) massive deployment is probably a question of the closest future. There is a lack of real IPv6 deployment experience in industry and there is also lack of experience in securing of IPv6 networks. The article introduces some results of IPv6 security study, testing, attacks examples etc. Several test was performed, the test platform was based mostly on Cisco network devices. The knowledge engineering appears as a promising method of IPv6 security exploration and experience exchange.

Knowledge Processing Using Ontopia and Source Mage GNU/Linux - II

Ladislav HAGARA

Abstract


This paper extends the paper Knowledge Processing using Ontopia and Source Mage GNU/Linux published in Cybernetic Letters in 2009. The paper presents the Source Mage GNU/Linux Topic Maps Ontology and the possibilities of using it together with Ontopia to support development of Source Mage GNU/Linux. Source Mage GNU/Linux is a source-based GNU/Linux distribution. Topic Maps is a standard for the representation and interchange of knowledge, with an emphasis on the findability of information. Ontology is a formal representation of knowledge as a set of concepts within a domain, and the relationships between those concepts. Ontopia is a complete set of open source tools for building, maintaining, and deploying Topic Maps based applications.

Knowledge Management in the Defence Area

Petr DO

Abstract


The article presents information and problems of Knowledge Management (KM) integration into the area of defence. The introductory chapter focuses on the emergence and current state of the issue. It compares it with the commercial sector and knowledge management implementation in other NATO countries. Then the definitions of basic terms in the field of knowledge engineering are given. KM as a discipline created by the development of the Semantic Web is one of its pillars. Various tools for creating knowledge-based applications and ontologies are described. The next chapter covers examples of analysis and creation of a domain knowledge base by using these tools. One of the sub-section is devoted to the construction of ontologies and creation of topic maps in specific software. It illustrates the appropriate methods and procedures as applied in knowledge-based software application solutions. KM is also about the management of knowledge. The methods of knowledge management are presented. The actual construction of a knowledge-based applications solution, the proposal of methodology for the defence area and the integration of KM into the existing environment is introduced in the penultimate section. All findings stem from the MENTAL project. The methodology or solutions that are presented here do not constitute a universal solution, but try to cover what is presented in different ways in practice, and especially a myriad of sources. Finally, the summaries present the findings gained from the MENTAL research project.

Knowledge Management System MENTAL

Ladislav BUŘITA, Vojtěch ONDRYHAL

Abstract


The article is based on the results of the research defence project called Network Enabled Capability Knowledge Management in the Army of the Czech Republic – MENTAL. It presents the experience of the implementation of ontology and knowledge base development in the technological environment of ATOM2. The article provides examples of the impact of technology on the ontology structure and the function of the knowledge system. The solution of users’ administration and the creation of the Community of Interest are introduced. The overview of the knowledge portal MENTAL is also included.
