Surprising Discoveries by Recommender Systems

Recommender systems apply data mining techniques to predict users’ interest on information, products and services among a tremendous amount of available items. Key to the success of recommender systems is user satisfaction. That cannot be achieved only by accurate recommendations. Recent work has focused on new measures that are beyond the accuracy of recommender systems. Serendipity is one of ...

Assessment of atmospheric dispersion from ANPP hypothetical accident based on Fukushima accident by HYSPLIT model

The atmospheric dispersion of Materials is one of the most important ways of spreading contamination of a NPP accident. In this study, the particle paths were calculated by HYSPLIT model (both pressure and AGL form of trajectory) horizontally and vertically at 0 and 1.5 meters above ground level during 15-day periods for 23& 24 November 2006 start times. Then, the releases values of Fukushima a...

T Dwarf Discoveries by 2 MASS

Over a dozen T dwarfs, brown dwarfs that exhibit methane absorption features at 1.6 and 2.2 μm, have been discovered by the 2MASS survey. We discuss how the search for these objects has been made, point out some of the limitations of using near-infrared data to find the warmest T dwarfs, and highlight a few of the more interesting T dwarfs that have been identified in 2MASS data.

Monument to the discoveries.

A week ago I was standing with my wife by the River Tagus in Lisbon, next to the Monument to the Discoveries. The monument is at the spot where Vasco da Gama set out to discover the southeast passage from Europe to Asia, past the Cape of Good Hope. Vasco’s discovery marked the beginning of the Portuguese maritime empire. At the furthest tip of Europe, Portugal was perfectly situated to found su...
