Self Organizing Maps (SOM) have been successfully applied in a lot of real world hard problems since their apparition. In this paper we present new topologies for SOM based on a planar graph. The design of a specific graph to encode prior information on the dataset topology is the central question addressed in this paper. In this context, star-shaped graphs are advocated for health monitoring a...

A new level-line registration technique is proposed for image alignment. This approach is robust towards contrast changes, does not require any estimate of the unknown shift between images and tackles some speci¿c problems due to image acquisition systems: ¿xed artefacts apparition or repetitive patterns that could lead to paring ambiguities. The registration by itself is performed by an ef¿cie...

Last week I admitted Mr. M in the predawn hours of an evolving M.I. I had forgotten his name. Erased the particulars of our prickly past until we came face to face the behind closed curtains of an emergency room bay. Through sleep-deprived eyes and the apparition of a pachyderm poised on my patient’s chest, I saw clearly what the years had hidden. Thankfully, there was business to conduct, orde...

In the last few years, communication between man and virtual world has been made easier with the apparition of smartphones. This paper presents a method allowing a smartphone user to recognize from any viewpoint a 3D model displayed on a screen. The model is selected from a 190 objects database and displayed rotating along the vertical axis. This method can be used to allow interaction with the...

In this paper, we give new solutions of the focusing NLS equation as a quotient of two determinants. This formulation gives in the case of the order 3, new deformations of the Peregrine breather with four parameters. This gives a very efficient procedure to construct families of quasirational solutions of the NLS equation and to describe the apparition of multi rogue waves. With this method, we...

Based on the fervor and devotion of Virgin Girdle Tortosa—which gained a strong establishment from 17th century onwards—this article explores possibility cause-effect relationship between apparition in cathedral 1178 Marian appendix contained troper-proser E-TO 135 (c. 1228–1264). By comparing narration miracle sequences this appendix, we can verify existence an early incipient veneration—both ...
