The overwhelming number of radio stations, both online and over the air, makes the choice of an appropriate program difficult. By profiling the program content of radio stations using Self-Organizing Maps we provide a reflection of a station’s program type and give potential listeners a visual clue for selecting radio stations. Profiles of current broadcasts indicate which program type a statio...

In 1976, Cameron et al. [2] proved that, if a finite generalized hexagon of order s admits a polarity, then either s or 3s is a perfect square. Their proof used standard eigenvalue arguments. Later on, Ott [3] showed that for a self polar finite thick generalized hexagon of order s, 3s always has to be a perfect square. His proof used Hecke algebras. It was surprising that one had to use this m...

We propose using profile compatibility to differentiate genuine and fake product reviews. For each product, a collective profile is derived from a separate collection of reviews. Such a profile contains a number of aspects of the product, together with their descriptions. For a given unseen review about the same product, we build a test profile using the same approach. We then perform a bidirec...

Résumé. La fusion d’informations fait intervenir plusieurs sources d’informations afin d’améliorer la décision en terme de certitude et de précision. Quelle que soit l’approche retenue pour réaliser la fusion d’informations, l’hypothèse d’indépendance est généralement une hypothèse forte et incontournable. Nous proposons dans cet article une approche permettant d’intégrer une mesure d’indépenda...

Exoplanets transiting bright nearby stars are key objects for advancing our knowledge of planetary formation and evolution. The wealth photons from the host star gives detailed access to atmospheric, interior orbital properties companions. ?2 Lupi (HD 136352) is a naked-eye (V = 5.78) Sun-like that was discovered three low-mass planets with periods 11.6, 27.6 107.6 d via radial-velocity monitor...

We describe strategies and tactics for detecting transiting planets, as learned from the experience of the XO Project. A key component is the web-enabled collaboration with a longitudinally-distributed Extended Team of dedicated volunteers operating small-aperture telescopes near their homes. We also quantify the (small) potential to discover transiting planets of M dwarfs from existing data su...

background: adverse effect of sun rays mainly uv ray on the human eye documented and protection of eyes is necessary using different methods such as, sun glasses. sunglasses are designed in different colors. the aim of this study was evaluation of the effect of different colors of sunglasses on the visual acuity, contrast sensitivity, stereopsis and color vision. methods: 81 normal subjects wer...
