In this paper we introduce a new framework for the development of context-aware knowledge by integrating the user's digital and physical environment. The developed knowledge can contribute to solve problems and challenges of wireless sensor networks within a context that is described by additional cyber-content. Sensor networks are exposed, intentionally or not, to dynamically changing network structures...
Human-Machine-Interfaces are with no doubt one of the constitutive parts of an automation system. However, it is not till recently that they have received appropriate attention in order to improve the design of SCADA applications in industrial domain. It is because of a major concern about aspects related to maintenance, safety, achieve operator awareness, etc has been gained. Even there are in the...
The widespread use of OPC UA specification in client/server data exchange in industrial environment introduces many benefits as it allows to keep open the market of the industrial applications, due to the presence of a standard, worldwide and vendor-independent specification. On the other hand, the use of a software infrastructures (complex in the case of OPC UA) between industrial applications and...
This article describes a systems and networks monitoring system that is based on the Nagios tool and can easily be supervised by its user. The system is Web-managed and equipped with advanced 3D visualization features in Flash format that improve its interaction and allow it to reproduce the real management environment in multiple browsers with acceptable load and response times. Also, anomalies in...
This paper focuses on the design of wearable system operation modes in context of cooperation between personal healthcare systems. The patient is currently provided with telemedical solutions for home care and seamless diagnosis based on selected vital parameters. When two or more specialized systems are applied for monitoring of the same subject, the possible interference and cooperation are in question...
