Phase change heat transfer in nanoporous shape-stabilised phase materials (ss-PCMs) is of great importance for the efficient utilization novel energy storage materials. However, lack thermodynamic properties hinders study on transfer. In this paper, we selected binary chloride salts (NaCl–KCl), promising high-temperature concentrating solar power, and computed their melting point using molecula...

The orientation of a massive binary undergoes a random walk due to gravitational encounters with field stars. The rotational diffusion coefficient for a circular-orbit binary is derived via scattering experiments. The binary is shown to reorient itself by an angle of order √ m/M during the time that its semi-major axis shrinks appreciably, where M is the binary mass and m the perturber mass. Im...

We consider two problems concerning locating change points in a linear regression model. One involves jump discontinuities (change-point) in a regression model and the other involves regression lines connected at unknown points. We compare four methods for estimating single or multiple change points in a regression model, when both the error variance and regression coefficients change simultane...

In the present work, the effect of the restitution coefficient on the numerical results for a binary mixture system of sand particles and char particles in a bubbling fluidized bed with a huge difference between the particles in terms of density and volume fraction has been studied based on two-fluid model along with the kinetic theory of granular flow. Results show that the effect of restituti...

Binary-defined 3D objects are common in volume graphics and medical imaging as a result of voxelization algorithms, segmentation methods, and binary operations such as clipping. Traditionally, renderings of binary objects suffer from severe image quality problems, especially when one tries to zoom-in and render the binary data from up close. We present a new rendering technique for discrete bin...

By means of an EPR investigation of Mo ions introduced into NaY zeolites by solid-state reactions, the location and coordination of Mo in zeolites were investigated. Two different locations, free and distorted tetrahedral, were found. The molecular orbital coefficient, ß, and the effective charge, Q, for the MO ions in a distorted tetrahedral structure were calculated and interpreted.

Recent spectroscopic models of active galactic nuclei have indicated that the recommended electron-ion recombination rate coefficients for iron ions with partially filled Mshells are incorrect in the temperature range where these ions form in photoionized plasmas. We have investigated this experimentally for Fe forming Fe, Fe forming Fe, and Fe forming Fe. The recombination rate coefficient was...
