MilkyWay@home echipa Romaniei

-----------------------------------

Modelarea galaxiei noastre in 3D prin folosirea resurselor combinate a mai multor calculatoare.
Cine are un PC puternic poate contribui. 

Echipa Romaniei numara doar 20 de membrii activi, si se afla pe locul 52 la Recent Average Credit si pe locul 106 la Total credit.

Cei doritori sa contribuie la modelarea 3d a galaxiei o pot face instaland programul Boinc Using data from the Sloan Digital Sky Survey, MilkyWay@home divides starfields into wedges of about 2.5 deg. width and applies self-optimizing probabilistic separation techniques (i.e., evolutionary algorithms) to extract the optimized tidal streams. The program then attempts to create a new, uniformly dense wedge of stars from the input wedge by removing streams of data. Each stream removed is characterized by 6 parameters: percent of stars in the stream; the angular position in the stripe; the three spatial components (two angles, plus radial distance from Earth) defining the removed cylinder; and a measure of width. For each search, the server application keeps track of a population of individual stars, each of which is attached to a possible model of the Milky Way.
