Here we present the overall objectives and approach of the SAPERE (" Self-aware Pervasive Service Ecosystems ") project, focussed on the development of a highly-innovative nature-inspired framework, suited for the decentralized deployment, execution, and management, of self-aware and adaptive pervasive services in future network scenarios. © Selection and(More)
The usability of remote controls for home entertainment systems like TV sets, set-top boxes, satellite receivers and home entertainment centers has reached overstraining complexity: about eight to ten remote controls with about sixty to eighty push-buttons each are typical for a home entertainment system setting today. To be able to harness the ever growing(More)
As a matter of convenience, many current consumer devices switch to reduced energy consumption modes when not active in use, to be instantly ready for use upon explicit user invocation. Therefore the " standby " energy dissipation of electric appliances and devices have remarkably raised energy consumption in homes, offices and buildings. To overcome this(More)
Quality function deployment (QFD) is a method for quality assurance developed for application in production processes. One prominent tool for implementing QFD is the House of Quality (HoQ), whose basic design principles have been left unchanged for the last decades. Modern concepts for handling product variability, most notably feature models, represent(More)
Enterprise resource planning (ERP) systems are often cumbersome to customize to a client's needs. Model-driven approaches promise to simplify these attempts. In this work we present an ERP prototype based on the Resource-Event-Agent (REA) business ontology that follows a "model-at-runtime" approach: one may customize the ERP system during runtime by(More)
The REA business model language is an established vehicle (i) to model businesses in terms of domain specific value chains and their key concepts and (ii) to capture business data in terms of accounting artefacts. REA has evolved into a specification that could drive web shops, enterprise/trading information systems, enterprise resource planning systems,(More)
—This paper presents a novel approach towards identity management strategies for application in large scale interactive systems while separating pure detection from the identity management processes. Detection is achieved by employing a scalable, modal, network-based, real-time multi-camera tracking system in which numerous cameras are used to cover large(More)
