EXtensible Java-based Agent Framework (XJAF) is a pluggable architecture of the hierarchical intelligent agents system with communication based on KQML. Workers, Inc. is a workflow management system implemented using mobile agents. It is especially suited for highly distributed and heterogeneous environments. The application of the above-mentioned systems(More)
Constraints are very important part of every database management system (DBMS). There are different taxonomies of constraints in every data model. In this paper we propose a constraint taxonomy for XML data model. One of the constraints that exists in the database design practice is the inverse referential integrity constraint (IRIC). In relational database(More)
L-IRL (Lola Industrial Robot Language) is procedural language for industrial robot programming. Offline and real-time programming system are main parts of robot programming system based on L-IRL programming language. System for robot programming is using object code as one of the main communication tools between different elements of the system. In this(More)
A database management system (DBMS) should provide capabilities for defining and enforcing certain integrity constraints that must hold for the data recorded in the database. These constraints are derived from the semantics of the data and from the rules of the system under study (SuS) that database represents. Every DBMS is based on a data model that(More)
Reports in library information system involve bibliographic cataloguing cards. XML Schema for modelling the concepts of bibliographic cataloguing card is described. All concepts of the main bibliographic cataloguing card are shown. Analysis of the capability of XML Schema language for representing the concepts of all types of the bibliographic cataloguing(More)
In this paper principles of modeling of a human centrifuge for pilot training, as a 3 DoF manipulator, are presented. The basis is a kinematic and dynamic model of the manipulator. The centrifuge represents a manipulator with three revolute joints. According to the D-H convention transformation matrices for the manipulator were derived. The problem of(More)
This paper presents distributed real-time robot control system implemented on the client and server modules. The client module is used to control the real robot and send commands to the server module. An application on the server side receives the commands that contain positions of robot joints read from encoders, displays current robot coordinates and 3D(More)
