A collaborative demand forecasting process with event-based fuzzy judgements

Philippe Wieser, Naoufel Cheikhrouhou, Omar Ayadi

Mathematical forecasting approaches can lead to reliable demand forecast in some environments by extrapolating regular patterns in time-series. However, unpredictable events that do not appear in historical data can reduce the usefulness of mathematical fo ...

Knowledge-Based Representation Of 3D Media

Alejandra Garcia Rojas Martinez

In recent years, 3D media have become more and more widespread and have been made available in numerous online repositories. A systematic and formal approach for representing and organizing shape-related information is needed to share 3D media, to communic ...

Reasoning with large ontologies stored in relational databases: The OntoMinD approach

Stefano Spaccapietra, Christine Parent

A major obstacle to the development of ontologies in support of the Semantic Web is the poor capability of current ontology techniques to handle very large ontologies, in particular regarding scalability of reasoners. This paper builds on the assumption th ...

An ontology-based approach for Product Lifecycle Management

Aristeidis Matsokis

Ontologies are rapidly becoming popular in various research fields. There is a tendency both in converting existing models into ontologies and in creating new models. In this work we are focusing on Closed-Loop Product Lifecycle Management (PLM) models. An ...

Automatic Construction and Multi-level Visualization of Semantic Trajectories

Karl Aberer, Stefano Spaccapietra, Christine Parent, Zhixian Yan, Dipanjan Chakraborty, Lazar Spremic

With the prevalence of GPS-embedded mobile devices, enormous amounts of mobility data are being collected in the form of trajectory - a stream of (x,y,t) points. Such trajectories are of heterogeneous entities - vehicles, people, animals, parcels etc. Most ...

An Ontology-Based Approach for Closed-Loop Product Lifecycle Management

Aristeidis Matsokis

The main goal of the Product Lifecycle Management (PLM) is the management of all the data associated to a product during its lifecycle. Lifecycle data is being generated by events and actions (of various lifecycle agents which are humans and/or software sy ...

Structuring and integrating human knowledge in demand forecasting: a judgemental adjustment approach

Naoufel Cheikhrouhou

Demand forecasting consists of using data of the past demand to obtain an approximation of the future demand. Mathematical approaches can lead to reliable forecasts in deterministic context through extrapolating regular patterns in time-series. However, un ...

Comprehensive system analysis of a multipurpose run-of-river power plant with holistic qualitative assessment

Anton Schleiss, Erik Bollaert, Philippe Heller

Alpine rivers have been channelized by significant river training works in the past two centuries and are now disconnected from their natural environment. In adition, their flow regime is often affected by hydropower plant operation. Also the risk of flood ...

Traduction des opérations de l'analyse historique dans le langage conceptuel des systèmes d'information géographique pour une exploration des processus morphologiques de la ville et du territoire

Eduardo Camacho-Hübner

Present work intends to conceive an interface between Urban Morphology and Geographic Information Science (GISc). This interface is considered as a space of exchange for knowledge exploration between several disciplines. The links pointed out from this the ...

Exploiting co-adaptation for the design of symbiotic neuroprosthetic assistants

Babak Mahmoudi

The success of brain-machine interfaces (BMI) is enabled by the remarkable ability of the brain to incorporate the artificial neuroprosthetic 'tool' into its own cognitive space and use it as an extension of the user's body. Unlike other tools, neuroprosth ...
