Article
Full-text available
The problem of air pollution with fine particulate matter and aerosols is more than topical and extremely serious. There is a need to develop and build reliable geographically distributed air quality monitoring networks to enable real-time data collection. The analysis of such data would help identify the origin of the particles and timely operatio...

Full-text available
Modern approach to manage the control network in an easy and reliable manner is to separate it into clusters. In this paper the opportunities for realization of a low cost Ethernet Fault Tolerant architecture for management of network resources are discussed. It is designed and implemented on the basis of the Purdue Model for Control Hierarchy and...
Conference Paper
Full-text available
The purpose of this paper is to discuss the opportunities for student training in control and modeling of technological plants using distributed control system with integrated data base. The initial configuration of the system comprises one programmable controller MIC 5000 Ce, two NETMASTER and server INTEL SR 2500. The latter contains the integrat...
Article
The main objective of this paper is to investigate the diversity of blade and modular servers, produced by main world manufacturers, like HP, IBM, Sun, Dell, Intel. Another objective is to present general criteria for the comparison of server platforms, called Total Cost of Ownership.
Conference Paper
Full-text available
The main objective of this paper is to consider the synthesis of Internet-based distributed control systems. For the purpose the main problems-time delays, timeout request, jitter and their sources and characteristics are considered, modelled and assessed. A methodology for design of robust controller is proposed. It is based on the internal-model...
