Void analysis as a test for dark matter composition? [PDF]
The Astrophysical Journal, 1996 We use the void probability function to compare the redshift--space galaxy distribution in the Perseus--Pisces survey with artificial samples from N-body simulations of standard cold dark matter (CDM) and broken scale invariance (BSI) models. Galaxies are identified as residing in peaks of the evolved density field in such a way as to reproduce both ...

Void Defects in Composite Titanium Disilicide Process [PDF]
Korean Journal of Materials Research, 2002 We investigated the void formation in composite-titanium silicide() process. We varied the process conditions of polycrystalline/amorphous silicon substrate, composite deposition temperature, and silicidation annealing temperature. We report that the main reason for void formation is the mass transport flux discrepancy of amorphous silicon substrate ...

Three-phase plane composites of minimal elastic stress energy: High-porosity structures [PDF]
International Journal of Solids and Structures 50(25-26),
4145-4160, 2013, 2013 The paper establishes exact lower bound on the effective elastic energy of two-dimensional, three-material composite subjected to the homogeneous, anisotropic stress. It is assumed that the materials are mixed with given volume fractions and that one of the phases is degenerated to void, i.e. the effective composite is porous.

Influence of the Void Structure on Thermal Performance in HGM/ER Composites
EnergiesThe heat transfer mechanism of hollow glass microsphere/epoxy resin composites (HGM/ER) is intricate, and the formation of void structures during material preparation complicates the prediction of thermal conductivity. To investigate the microscopic heat

Influence of voids on the flexural resistance of the NCF/RTM6 composites
Procedia Engineering, 2011 AbstractA major difficulty to achieve maximum weight savings in the manufacture of composite structural components, is the tendency of these materials have the formation of voids and cracks in the interior and surface components. In aeronautical applications, controlling the volume fraction of fibers, resins and empty the components of composite is ...
