INFORMATIONAL ENTROPY IN SIMULATION OF ONE-DIMENSIONAL RANDOM FIELDS
TASK Quarterly, 2002 The entropy H of a continuous distribution with probability density function f(•) is defined as a function of the number of nodes (n) in a one-dimensional scalar random field.

Characterisation of InAs/GaAs short period superlattices using column ratio mapping in aberration-corrected scanning transmission electron microscopy [PDF]
, 2012 The image processing technique of columnratiomapping was applied to aberration-corrected high angle annular dark field (HAADF) images of shortperiod MBE (molecular beam epitaxy) grown InAs/GaAssuperlattices. This method allowed the Indium distribution to

A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data
Advanced Engineering Materials, EarlyView.Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.

X-band crab cavities for the CLIC beam delivery system [PDF]
, 2008 The CLIC machine incorporates a 20 mrad crossing angle at the IP to aid the extraction of spent beams. In order to recover the luminosity lost through the crossing angle a crab cavity is proposed to rotate the bunches prior to collision.

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing
Advanced Engineering Materials, EarlyView.This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Twisted EM beams with structured correlations
Optics Letters, 2018 The possibility of restructuring the spectral density of a random light beam up to three times along the propagation path in free space is demonstrated. This can be achieved by prescribing special correlations and different twist factors (by magnitude and/or direction) in the two mutually orthogonal electric field components in the source plane.
