Numerical simulation of grain-size effects on creep crack growth by means of grain elements [PDF]
, 1998 The effect of grain size on creep crack growth is investigated by means of a numerical technique in which the actual crack growth process is simulated in a discrete manner by grain elements and grain boundary elements.

Synthesized grain size distribution in the interstellar medium [PDF]
, 2012 We examine a synthetic way of constructing the grain size distribution in the interstellar medium (ISM). First we formulate a synthetic grain size distribution composed of three grain size distributions processed with the following mechanisms that govern

X-ray Halos and Large Grains in the Diffuse Interstellar Medium [PDF]
, 2001 Recent observations with dust detectors on board the interplanetary spacecraft Ulysses and Galileo have recorded a substantial flux of large interstellar grains with radii between 0.25 and 2.0 mu entering the solar system from the local interstellar ...

A computer program for grain-size data [PDF]
, 1965 The computer program presented here seeks to improve estimation of statistical parameters for grain-size data by use of interpolated values. Interpolation is made by fitting a series of overlapping parabolas to the data, and follows the method of Snyder

Novel sputtering-technology for grain-size control [PDF]
, 2004 In this paper, we present a description of a novel high-rate plasma sputtering system that allows the control of grain size in sputtered films. Additionally, the system has the advantage of a better utilization of the target material (around 80% to 90 ...

Remote sensing of sediment characteristics by optimized echo-envelope matching [PDF]
, 2003 A sediment geoacoustic parameter estimation technique is described which compares bottom returns, measured by a calibrated monostatic sonar oriented within 15° of vertical and having a 10°–21° beamwidth, with an echo envelope model based on high ...

Dust Grain-Size Distributions From MRN to MEM [PDF]
, 2003 Employing the Maximum Entropy Method algorithm, we fit interstellar extinction measurements which span the wavelength range 0.125-3 micron. We present a uniform set of MEM model fits, all using the same grain materials, optical constants and abundance ...
