A consumer may be interested in buying a bundle of items, where any one item in the bundle may not be of particular interest. The emergence of online auctions allows such users to obtain bundles by bidding on different simultaneous or sequentially run auctions. Because the number of auctions and the number of combinations to form the bundles may be large,(More)
This paper presents a new design and evaluation of customizable gesture commands on pen-based devices. Our objective is to help users during the definition of gestures by detecting confusion among gestures. We also help the memorization gestures with the guide of a new type of menu “Customizable Gesture Menus”. These menus are associated with an evolving(More)
This paper presents a new method for designing a recognition engine to define customizable gesture commands on pen-based devices. Such gesture commands require an evolving classifier that can start from few data samples and learn incrementally. Gesture commands use give rise to a cross-learning situation where the user has to learn and memorize the command(More)
In this paper, we propose a method allowing us to compare a speciication of the intended semantics of a given logic program with the operational one. We compute, using a version of Knuth Bendix completion procedure, a nite set of rewrite rules synthesizing the answers w.r.t. a goal and we compare this set of equations with the given speciication, supposed(More)
This paper presents a new low cost GNSS Software (SW) receiver for Microsatellites. Syrlinks (Bruz, FRANCE) has been chosen by CNES for developing and manufacturing this equipment which should be tested on board the scientific microsatellite named MICROSCOPE that will be launched in 2015. The GNSS receiver under development is a highperformance equipment(More)
