The European agenda for 2020 sets out the challenge of improving the quality of life of European citizens and thereby increasing life-expectancy by two years. The objective of the study and proposed system presented in this paper is to promote physical activity among older people in a way that ensures the elderly person's welfare and health by designing healthy exercise routines, supported by a biometric...
This work presents the architecture, modelling, simulation, and physical implementation of a versatile, scalable system for use in common-type waste-bins that can perform and transmit accurate fill-level estimates while consuming minimal power and consisting of low-cost embedded components. The sensing units are based on ultrasonic sensors that provide ranging information which is translated to fill-level...
The advances in the wearable devices and Artificial Intelligence domains highlight the need for ICT systems that aim in the improvement of human's quality of life. In this paper we present the sleeping tracking component of an activity and sleeping tracking system. We present the sleep quality assessment based on EEG processing and support vector machines with sequential minimal optimization classifiers...
This paper compares two supervised learning algorithms for predicting the sleep stages based on the human brain activity. The first step of the presented work regards feature extraction from real human electroencephalography (EEG) data together with its corresponding sleep stages that are utilized for training a support vector machine (SVM), and a fuzzy inference system (FIS) algorithm. Then, the...
Nowadays in modern and ubiquitous computing environments, it is imperative more than ever, the necessity for deployment of Wireless Sensor Networks, which can be used as backbone networks in order to convey different types of digital contents that are locally generated by public utility application servers. Such environments must be developed satisfying the basic security requirements for real-time,...
A modular architecture for power constrained embedded devices which leverages an agent based middleware in order to impose intelligence over critical infrastructures which require real time actions is always desirable in the case of Wireless Sensor Networks. The main objective of such architecture is the integration of a Wireless Sensor Network with the internet. This objective indicates the need...
Telemetric monitoring of vital parameters of patients with chronic diseases is recognized to improve their medical condition and hence their quality of life. It also improves treatment adjustments, reaction time in acute cases and helps to reduce duration and costs of hospitalization. As a result of this, there are plenty of products and solutions for personal health monitoring available today that...
As dynamicity in networks and interoperability in DRM systems become the critical aspects in networked ecosystems, new emerging frameworks for secure, user-converged digital content delivery are required. In this work, we argue that the IPMP and REL components of MPEG-21 framework should be utilized in order to achieve a user-adaptive and interoperable DRM architecture.
This paper describes a wearable health monitoring system integrated into a broad telemedical infrastructure allowing high - risk cardiovascular patients to closely monitor changes in their critical vital signs and get experts feedback to help maintain optimal health status. Consistent with the major challenge to provide good quality and reliable health care services to an increasing number of people...
The introduction of semantics via ontologies in the industrial environment combined with autonomous agents for the decentralization of production processes has drawn a lot of attention. The common denominator in all proposals attempting to combine semantics and intelligent agent was the semantic gap between them which, at best, was attempted to be bridged with an auxiliary ontology. In this paper...
The paper deals with the problem of modeling and implementation of distributed automation systems for manufacturing applications. In particular, a novel approach has been conceived. A suitable meta-model of the production system has been derived, compliant with the state-of-the-art industrial standards. After the compilation and validation stages, an ontology is derived containing all the necessary...
As networks become more and more complicated and applications more and more demanding, a very common network topology for state-of-the-art multimedia applications supporting emerging user - centric frameworks is a heterogeneous wired/wireless architecture. A network architecture solution for Indoor/Outdoor heterogeneous networking applications, to support both multimedia and sensor applications suitable...
The manufacturing environment is characterized by a high degree of heterogeneity. The seamless integration of MES and Shop-Floor layers poses a significant challenge. Industrial manufacturing ontologies provide the necessary semantics for such and integration. A gap nevertheless exists between the industrial ontology semantics and the behaviour and activity model utilized by a multi-agent system that...
Collaborative B2B e-commerce provides enterprises with the necessary level of flexibility and efficiency to retain competitiveness under the increasingly turbulent business environment. Widely accepted XML-based frameworks like RosettaNet may be utilized to provide generic inter-enterprise B2B infrastructure. This paper presents an innovative approach towards utilizing RosettaNet in combination with...
This paper discusses the design and the development of a control architecture for reconfigurable manufacturing systems. It presents the approach proposed by the PABADIS' PROMISE European research project which targets the issues of reconfigurability, flexibility, and efficiency in the context of the interaction among the three levels of the control pyramid (ERP, MES, Field). The key feature of the...
Enterprise integration is significant for the enforcement of novel business models in an enterprise/industry. The great heterogeneity of systems/applications in the enterprise environment requires the introduction of interoperability aspects in order to resolve integration problems in a flexible and dynamic way. Our approach introduces an advanced enterprise semantic model representing both enterprise...
Collaborative e-commerce provides an increased level of flexibility and dynamicity and generates an entrepreneurial competitive edge. Widely accepted implementation frameworks like RosettaNet may be utilized to provide generic inter-enterprise B2B infrastructure. This paper presents an innovative approach towards utilizing RosettaNet in combination with Web services and ontologies for the enforcement...
Ontologies present a state-of-the-art technology for the provision of machine-readable semantics. Its utilization for the annotation of end-to-end enterprise/industrial processes characterizing advanced collaborative business models, largely contributes to enterprise interoperability, flexibility and component reusability. Our work in this paper emphasizes on the use of ontologies in combination with...
