This paper presents one solution of a system of interconnections in modern commutation systems. An emphasis is put on a signal integrity issues and technological aspects of PCB design and production in such systems that contain a great number of conducting layers. The paper represents one implementation solution of this kind.
During the project we were working on physical conflicts occurred in a multiagent system. In order to resolve the problem many different conflict resolution strategies were examined and many proposed solutions found. In this paper we explore conflicts as well as their causes and possible solutions. Based upon this research we implemented a centralized solution and added a reactive agent in the database...
Ontologies are nowadays one of the most popular and widespread means of knowledge representation. They are also considered as a basis for new technologies of Semantic Web. Web ontologies are being developed mostly in OWL, a language whose one part is based on description logics. Since one of the steps in ontology development is domain modeling, it would be favorable to create a domain model exactly...
For more than 20 years relational model is the most important database model. So, it is examined in the most various ways. A very important concept in the relational model is the concept of dependencies, especially functional dependencies. It is proven that functional dependencies can be represented by formulae of prepositional or predicate calculus. There are several systems of transforming functional...
The paper describes knowledge reasoning using lattices in F-logic. The objective of this paper is to show that logic programming languages with second order syntax and with object oriented approach (HiLog + F-logic) provide adequate support for lattice representation and manipulation. A description on how lattices can be represented using F-logic formalism and some important rules for lattice manipulation...
The paper addresses data integration for heterogeneous knowledge sources in the semantic Web domain. The objective of the works is to show that logic programming languages with second order syntax and with object oriented approach (HiLog+F-logic) provide adequate support for a data integration system. In particular, object oriented approach supporting the F-logic language provides a natural translation...
Stroke is an acute medical emergency called ''brain attack'' representing a disease of the circulatory system, caused by the rupturing or the blockage of an artery. Recent data have shown that about 72-86% of strokes are ischemic, 9-18% are caused by hemorrhage while the rest are undefined. Stroke is one of the leading causes of death worldwide, representing a huge public health concern, because of...
We consider some relationships among the knowledge operators (Ki, Kj), the past temporal operator (the once operator), and the future temporal operators (the next operator, the eventually operator, the always operator) in multi-agent systems. These relationships describe agent properties in multi-agent systems (the properties relate knowledge of two agents): if agent i has known F: then agent j will...
