Heesop Kim et al. 83 This paper examines the correlations between user characteristics and their preferences for two selected features of Web-based OPAC systems. User characteristics identified in this study were age, gender, educational status, computer skills and OPAC experience. Usability features included interaction styles, character and image on screen, browsing and navigating style, scre...
Here we present the New York University Value-Added Galaxy Catalog (NYU-VAGC), a catalog of local galaxies (mostly below z ≈ 0.3) based on a set of publicly-released surveys matched to the Sloan Digital Sky Survey (SDSS) Data Release 2. The photometric catalog consists of 693,319 galaxies, QSOs and stars; 343,568 of these have redshift determinations, mostly from the SDSS. Excluding areas maske...
Widespread access to the Internet resulted in the explosion of digital music. People continue to download large collections of music files often stored in directory structures classified by artist or genre. A distributed catalog, scalable to a large number of users, storing classification information of each user would prove very useful. Users may search the catalog to identify other users shar...
Abstract The CatWISE2020 Catalog consists of 1,890,715,640 sources over the entire sky selected from Wide-field Infrared Survey Explorer (WISE) and NEOWISE survey data at 3.4 4.6 μ m (W1 W2) collected 2010 January 7 to 2018 December 13. This set adds two years that used for CatWISE Preliminary Catalog, bringing total six times as many exposures spanning 16 large a time baseline AllWISE catalog....
The new, global catalog of 75,919 impact craters on Mars has been compiled entirely by a computer algorithm. Using crater depths listed by the new catalog global maps of depth/diameter ratio are created. The global pattern of crater depths is consistent with the existence of the cryosphere at depths that decrease toward the poles. Introduction: If left to traditional manual surveys, the fractio...
