Music. Radio. The internet. Three very interesting fields which are linked in this project on internet radio stations. A comparative study of existing radio stations is performed. Weaknesses and problems in current internet radio stations, as exposed by the comparative study, are identified. We outline the general problems observed. In particular, focus is placed on automatic music selection. O...

This paper presents an automatic approach to generate unstructured tetrahedral meshes in the context of composite or heterogeneous geometry. Using B-Rep concepts and specific adaptations of advancing front mesh generation algorithms, this approach guarantees, in a simple and natural way, mesh continuity and conformity across the interior boundaries of a composite domain. This method presents a ...

We define combinatorial principles which unify and extend the classical results of Steinhaus and Piccard on the existence of interior points in the distance set. Thus the measure and category versions are derived from one topological theorem on interior points applied to the usual topology and the density topology on the line. Likewise we unify the subgroup theorem by reference to a Ramsey prop...

Abstract Using robots to replace human beings achieve large-scale automatic operations has become an inevitable trend. Wall-climbing have important application value in the field of aerial work. For existing wall-climbing limitation on movement flexibility and overcome own gravity by adsorption friction, this paper innovatively proposes a robot with suspension traction, back push McNum wheel dr...

In this paper we present a formant database of Arabic used to evaluate our new automatic formant tracking algorithm based on Fourier ridges detection. In this method we have introduced a continuity constraint based on the computation of centres of gravity for a set of formant candidates. This leads to connect a frame of speech to its neighbours and thus improves the robustness of tracking. The ...

We show that principles from nonstandard analysis hold to some extent for nonlinear generalized functions. The generalized functions under consideration are constructed as families of functions modulo a free filter, as it is usually done in applied analysis. In contrast with models of nonstandard analysis, we do not require the filter to be an ultrafilter. The principles are intended to be used...

We study full groups ofminimal actions of countable groups by homeomorphisms on a Cantor space X, showing that these groups do not admit a compatible Polish group topology and, in the case of Z-actions, are coanalytic non-Borel inside Homeo(X). We then focus on the closure of the full group of a uniquely ergodic homeomorphism, elucidating underwhich conditions this group has a comeager (or, equ...

Automatic newspaper design requires feature organization. An intermediary between an article database and the graphic designer is implemented that organizes features with regard to their style and content. Topics are determined and style assessed through simple keyword analysis augmented by various content-understanding heuristics. Articles are grouped by two means: comparison against predefine...
