From February 13 to May 13, 2000, the Near Infrared Spectrometer (NIS) instrument on the Near Earth Asteroid Rendezvous (NEAR) mission obtained more than 200,000 spatially-resolved 800 to 2500 nm reflectance spectra of the S-type asteroid 433 Eros. An important subset of the spectra were obtained during a unique opportunity on February 13 and 14, when the(More)
Two model problems for stii oscillatory systems are introduced. Both comprise a linear superposition of N 1 harmonic oscillators used as a forcing term for a scalar ODE. In the rst case the initial conditions are chosen so that the forcing term approximates a delta function as N ! 1 and in the second case so that it approximates white noise. In both cases(More)
The perceptibility and acceptability of small color differences (ΔE* <5) were investigated using 66 textile-based color difference pairs around a CIE blue color center. Samples were polyester fabrics dyed with disperse dyes under well-controlled dyeing procedures and using precise recipe prediction methods. Each pair was assessed three times by 26 observers(More)
Introduction: The Stardust spacecraft carries the first sample of contemporary interstellar dust to be returned to terrestrial laboratories for analysis. Here we describe a project called Stardust@home, which has the goal of identifying these tiny particles in the Stardust Interstellar Collector using volunteers. We present measurements of the performance(More)
