Applications Based on Ontology or Database

Ladislav BUŘITA

Abstract


The article presents two approaches to the creation of applications working with information: an approach driven by o ntology or the one driven by a database. The first approach is repre sented by the application based on Knowledge Management System supporting cooperation of military universities (MilUNI) , and the second approach is introduced by the application based on Database Management System Postgres for processing the information about university science and research (IS- SID). The article presents the structure and functions of the applications. The approaches are compared, which results in stipulating their potential benefits and problems of the specific applications development.

Training of the Piecewise Linear Neural Network Used for Process Control

Petr DOLEŽEL, Martin MARIŠKA, Libor HAVLÍČEK

Abstract


This paper deals with a training of special topology of feedforward artificial neural network – artificial neural network with linear saturated activation functions in hidden neurons. This network is suitable to nonlinear processes control system design. In first paragraphs, motivation of this work is described. Then, possibilities of the training are introduced and at the end of the paper, the experiment results, which prove eligibility of the approach, are presented.

Automation of Day-to-Day Operational Processes of a Knowledge Engineer

Vojtech ONDRYHAL

Abstract


To hold a knowledge base up-to-date requires quite substantive endeavor of the knowledge engineers. The aim of the tools presented in the paper is to help the knowledge engineer with his tedious work. The first tool a2doc generates human readable documentation of an existing knowledge base. The second tool, the more complex one, creates the pieces of information from the text base and the appropriate ontology. The generated items can be then imported into the knowledge base. Both tools save time of the knowledge engineers.

Information Portal MilUNI for Military Universities Cooperation

Ladislav BUŘITA

Abstract


The paper describes the Knowledge Management System (KMS) about military universities (MilUNI), mostly in the NATO environment, but it also includes all European countries. The goal of the MilUNI is to support the cooperation among uni-versities in education, research, and the staff and students exchange. The system is based on the Topic Maps theory using the AToM software. Special attention is paid to the ontology design, Knowledge Base (KB) development, and application processing when using the KMS. The KMS includes the KB with interface for administrator, architect, and editor and the Knowledge Portal with user interface. Related work is analyzed. The search procedures in the KMS are mentioned. The pa-per concludes with suggestions for the further development of the system.

Software Support for Task Force Creation

Vlastimil Malý

Abstract


Modularity of military units’ structure contributes to the thoughtful and purposeful utilization of operational capabilities, with regard to the nature of the environment where military units are deployed. This article describes a new approach to the planning process and new possible way of selection forces for international operations based on modular structures and units’ capabilities required for particular operation. The article describes the options of original software application developed during the “STRUCTURE” project solution aiming as a support for staff officers in the preparatory phase of oper ational planning.

The New Reality of Cyber Warfare

Petr Hrůza

Abstract


Dependence on cyber space is not a frequent topic of discussion; the reason might be that people fear possible abuse of
cyber space or they just do not understand the center of the problem. Cyber space is used more and more – which increases
the dependence. The dependence can be abused in case of a terrorist or cyber attack. Now, this is the space where future
wars can take place.

Current Trends in the Preparation of Security Management

Oldřich Lunáček

Abstract


For activities of the organization it is necessary to prepare personnel for fulfilling their missions. These people must
be professionally trained and be ready on the highest level. Nowadays we have to challenge with the overload of the sources
and information. Any organization needs to setup effective system of preparation. Very useful tools are knowledge
management systems and learning management systems. The organization can achieve with using of these tools better level
of preparation and personnel can prepared not only in office, because personnel can be nearly anywhere. It is absolutely
essential to deal with possible usage of any tool which can help with training of the security management. These people
have to clearly understand terms, roles, associations, documents and relations between them etc.

Evaluation of approaches to MENTAL

Kamil Halouzka

Abstract


The purpose of this article, “Evaluation of approaches to MENTAL” is a concise description of the MENTAL knowledge, analyze the history of user accesses a staff information system to information published in the atom2 and an analysis of knowledge-based approach in terms of users. In addition, emphasis is placed on the evaluation of the most visited concepts connection between concepts and also the analysis of visitors each month.

Changes of the Mollusk Neuron Action Potential Parameters Over the Recurrent Intracellular Stimulation

Besarion Partsvania, Tamaz Sulaberidze, Zurab Alimbarashvili

Abstract


Waveform of the action potential (AP) was thought to be constant during long period. This point of view suggests that waveform of AP does not contain any information. However, continues evidences show opposite – the waveform of the AP is not constant and it contains some information. We have shown that AP parameters are broadened if neuron is stimulated with recurrent injection of intracellular short current impulses. This broadening follows to repetitive spiking induced by repetitive current injection. On the other hand such kind of stimulation causes neuron habituation to the stimuli, i.e. neuron declines all stimuli. The aim of present work was to give answer on the question: Do AP parameters contain some information about the process of habituation? Answer is positive. We have shown that AP parameters contain information about the habituation. Amount of this information depends on number deposited stimulus. Mentioned information was determined experimentally by the means of measurements. Experiments were carried out on the mollusk single neuron. Standard microelectrode technique was used in experiments.

The Combat Effectiveness Model of Air Operation Centre

Nada JELINKOVA, Vojtech MAJEK

Abstract


For the realistic war games simulation there is a need to express operator abilities by a mathematical function. This paper deals with the combat effectiveness model of the air operation centre, which derives from the theory of probability. This model describes the analysis and the quantification of stressful factors by which can operator meet in time of peace, crises and war. The model is simply applicable to every entity in the command and control structure and it can be used for training and exercises purposes or more precisely for simulations representing the human behaviour. Instead of possible evaluation, the paper contains the key factors which influence the working process and some important results clarifying the impact of the 24hours duty at human organism.
