A Software Product Line (SPL) reuses software assets to implement products that share a significant set of their features. When developer needs generate new product, the selection features determines which components and source code are assembled together as product. In recent years, Database Laboratory has been working with SPL tech- nologies in field Geographic Information Systems (GIS). Our ...

The Olga project has developed an animated agent interface for information services. The interface combines a graphical interface, spoken dialogue and an animated 3D ‘human-like’ character for multimodal input and output. The interaction is intelligently managed using techniques derived from spoken dialogue but extended for the graphical modality. The Olga agent is innovative in combining a spo...

In order to prevent the severe slugging flow regime in multiphase transport pipelines, active feedback control is the recommended solution. Instead of elaborated models such as CFD and OLGA models, a simple dynamical model with few state variables is required in a model-based control system. We propose a new simplified dynamical model for severe slugging flow in pipeline-riser systems. The prop...
