A computer tomography problem in wave approximation" . Goncharsky A.V., Romanov S.Y. This paper deals with the development of methods and algorithms for solving direct and inverse engineering seismic problems on parallel-architecture clusters. The methods employed are based on tomography approaches in the framework of a scalar wave hyperbolic-type model with consideration of a special experiment design. ... The work was supported by the Russian Foundation for Basic Research (05--01--08068). ...
... Structure of Data . ... Catalog . ... In SAI OCL Catalog, we introduce our work on investigation of the Milky Way system of open star clusters. The main goal of our study is a search for new clusters using huge surveys. 168 new clusters have been already discovered by us using J,H,Ks data from 2MASS point source catalog. ... For 141 new clusters, we found their physical parameters using J,H,Ks data from 2MASS catalog and, for a number of clusters, our UBVRI CCD observational magnitudes. ...
