Assembly of hard spheres in a cylinder: a computational and experimental study

, 2016
Hard spheres are an important benchmark of our understanding of natural and synthetic systems. In this work, colloidal experiments and Monte Carlo simulations examine the equilibrium and out-of-equilibrium assembly of hard spheres of diameter $\sigma ...

Laboratory simulations of astrophysical jets and solar coronal loops: new results [PDF]

, 2010
An experimental program underway at Caltech has produced plasmas where the shape is neither fixed by the vacuum chamber nor fixed by an external coil set, but instead is determined by self-organization.

Thermophysical Properties of the Desulphurization Slags With Various CaS and CaO/Al2O3 Ratio

Advanced Engineering Materials, EarlyView.
This article investigates how CaS content and the CaO/Al2O3 ratio influence the thermophysical properties of desulphurization slags. Using experimental measurements and thermodynamic simulations, this study reveals complex effects on viscosity, surface tension, and density, providing new insight into slag structure and phase behavior under ...

Polarization--universal rejection filtering by ambichiral structures made of indefinite dielectric--magnetic materials

, 2008
An ambichiral structure comprising sheets of an anisotropic dielectric material rejects normally incident plane waves of one circular polarization (CP) state but not of the other CP state, in its fundamental Bragg regime.

Hα Doppler shifts in a tornado in the solar corona [PDF]

, 2016
Context. High resolution movies in 193 Å from the Atmospheric Imaging Assembly (AIA) on the Solar Dynamic Observatory (SDO) show apparent rotation in the leg of a prominence observed during a coordinated campaign. Such structures are commonly referred to

Numerical Study on the Effects of Helix Diameter and Spacing on the Helical Pile Axial Bearing Capacity in Cohesionless Soils

Journal of the Civil Engineering Forum
The methods employed to calculate the axial bearing capacity of a helical pile depends on the shear failure model around the pile, which is also influenced by the spacing and diameter of the helical plates.

Development of an inflight centrifuge screw pile installation and loading system [PDF]

, 2016
To simulate the prototype installation behaviour of screw piles at realistic confining stress lev-els, a new installation and loading rig, consisting of two independently-controlled servo-motor drive systems was developed to allow screw pile models to be

Interaction of Ladle Slag With Varying SiO2 Content and Recyclate‐Based MgO–C Refractories

Advanced Engineering Materials, EarlyView.
Ladle slags (CaO/Al2O3 = 1) with 1–20 wt% SiO2 were investigated in contact with industrial MgO–C refractories fabricated from fresh magnesia and 50 wt% recyclate. The sessile drop method at 1600°C reveals intensive gas formation, delayed slag infiltration in recyclate‐based samples, and, under high‐SiO2 slag, formation of a dense MgAl2O4‐rich ...

Laboratory Investigation of the Behavior of Helical Piles under Monotonic Loading at Different Loading Speeds [PDF]

مهندسی عمران شریف
Today, one of the primary challenges faced by geotechnical engineers in dealing with problematic soils is to choose a suitable improvement method that, in addition to strengthening the soil, does not cause harmful damage to the environment. Helical piles
