We report an investigation to determine the topology of an arbitrary network of video cameras observing an environment. The topology is learnt in an unsupervised manner by temporal correlation of objects transiting between adjacent camera viewfields. We extract this information in two steps, firstly identifying the principal entry and exit zones associated(More)
The so-called " TV White Spaces " (TVWS) are locally underutilized portions of the terrestrial TV bands and occur as a by-product of the Digital Switchover taking place in most countries across the globe. Thanks to the very good characteristics of the TV bands in terrestrial radio communications, the exploitation of TVWS for local-or regional-area wireless(More)
This paper addresses the applicability and interoperation of standards and emerging technologies for the operation and management of ATM networks. The issue is tackled from a practical perspective based on experiences gained through the design, realisation and experimentation of a system developed by the ACTS AC208 REFORM project. Assuming an ATM-based(More)
In this paper, we focus on the bootstrap operation of a publish/subscribe information centric network. We consider a set of interconnected network nodes and describe how they organize themselves into a fully functional network by publishing and subscribing to control plane information. Network bootstrap includes establishing point-to-point communication(More)
Future Internet network management systems are expected to incorporate self-x capabilities in order to tackle the increased management needs that cannot be addressed through human intervention. Towards this end, Self-NET developed a self-management framework based on the introduction of cognitive capabilities in network elements. In this paper, the(More)
Red grape pomace (RGP) and onion solid wastes (OSW) were used as raw material to produce flavonoid-enriched extracts, using ultrasound-assisted solid-liquid extraction. The extraction medium used was composed of water and glycerol and under the conditions used the extraction of flavonoids from both materials was shown to obey first-order kinetics. Maximum(More)
Nowadays, users are reachable through a number of telecommunication devices, network operators, as well as services and applications. The calling users if provided with the appropriate information can manually select the most suitable way of communication. Although this capability already affects existing business models, the lack of a transparent and a(More)
Recent advances in low-cost sensor technologies, such as Microsoft Kinect and Leap Motion allow bare hand or full body interactions to be easily included in interactive 3D applications. It has already been recognized that museums and heritage institutions can significantly benefit from this new paradigm by providing a more experiential and engaging approach(More)
A novel natural low transition temperature mixture (LTTM), composed of glycerol and ammonium acetate (molar ratio 3:1), was tested for its efficacy as a solvent in recovering phenolics from chlorogenate-rich agri-food solid wastes, including potato peels (PPs), eggplant peels (EPPs), and spent filter coffee (SFC). The efficacy of this solvent was compared(More)
