Abstract The digitized format of microstructures, or digital plays a crucial role in modern-day materials research. Unfortunately, the acquisition microstructures through experimental means can be unsuccessful delivering sufficient resolution that is necessary to capture all relevant geometric features microstructures. resolution-sensitive microstructural overlooked due insufficient may limit o...

The characterization of materials supports their development and in particular of superconductors, for their technological applications. Scanning electron microscopy (SEM) is one of these characterization techniques, whose data is used to estimate the properties, determine the shortcomings and hence improve the material. The phenomenon of superconductivity initially develops within the grain an...

The elastic energy of a multiphase solid is a function of its microstructure. Determining the infimum of the energy of such a solid and characterizing the associated optimal microstructures is an important problem that arises in the modeling of the shape memory effect, microstructure evolution, and optimal design. Mathematically, the problem is to determine the relaxation under fixed phase frac...

A general formalism is developed to statistically characterize the microstructure of porous and other composite media composed of inclusions (particles) distributed throughout a matrix phase (which, in the case of porous media, is the void phase). This is accomplished by introducing a new and general n-point distribution function HA and by deriving two series representations of it in terms of t...

Backscatter SEM imaging and small-angle neutron scattering (SANS) data are combined within a statistical framework to quantify the microstructure of a porous solid in terms of a continuous pore-size distribution spanning over five orders of magnitude of length scale, from 10 A to 500 microm. The method is demonstrated on a sample of natural sandstone and the results are tested against mercury p...

The advancement of transmission electron microscopy has made it possible to analyze the metallographic structure of steel products on a nanoscopic scale, which leads to the detail understanding of microstructures such as fine precipitates and grain boundaries. The application of the characteristic technology to commercial steel products requires consistency in the structural analysis of steel f...

Metal casting processes routinely used in the foundry industry (e.g., gravity or pressure casting) are subject to a wide range of operational parameters. Since there is close correlation between solidification conditions, microstructure, and properties, effects thermal parameters alloying elements on microstructure designs resulting properties cast alloys have stimulated new research interest. ...

BACKGROUND Exposure to alcohol during gestation is associated with CNS alterations, cognitive deficits, and behavior problems. This study investigated microstructural aspects of putative white matter abnormalities following prenatal alcohol exposure. METHODS Diffusion tensor imaging was used to assess white matter microstructure in 27 youth (age range: 8 to 18 years) with (n = 15) and without...

To avoid the pitfalls of self-reported dietary intake, wearable sensors can be used. Many food ingestion sensors offer the ability to automatically detect food intake using time resolutions that range from 23 ms to 8 min. There is no defined standard time resolution to accurately measure ingestive behavior or a meal microstructure. This paper aims to estimate the time resolution needed to accur...
