We discuss the occurrence of crossing points in the magnetization temperature (m,T ) plane within the framework of critical phenomena. It is shown that in a two-dimensional superconducting slab of thickness ds mz (δ) versus temperature T curves measured in different fields H = H (0, sin (δ) , cos (δ)) will cross at the critical temperature Tc of the slab. In contrast, in a 3D anisotropic bulk s...

Mathematical models have been developed and applied to investigate the composition distributions that arise during steel grade changes in the continuous slab casting processes. Three-dimensional turbulent flow and transient mixing phenomena in the mold and the strand were calculated under conditions corresponding to a sudden change in grade. The composition distribution in the final slab was th...

[1] Subduction zones alter the upper plate in a variety of ways, including metasomatism via slab-derived fluids and accretion of exotic terranes. These processes should produce distinctive seismic signatures, as seismic velocities are sensitive to compositional variations. A new method is developed to estimates depths to interfaces and Poisson’s ratio (Vp/Vs ratio) for dipping layered structure...

We present the first study of the phase diagram of a thick film of superfluid He confined within a nanofabricated slab geometry. This cryogenic microfluidic chamber provides a well-defined environment for the superfluid, in which both the regular geometry and surface roughness may be fully characterised. The chamber is designed with a slab thickness d = 0.6 μm and 3 mm thick walls to allow pres...

It is known that an acoustic wave incident on an infinite array of aligned rectangular blocks of a different acoustic material exhibits total transmission if certain conditions are met [1] which relate the unique ”intromission” angle of incidence with geometric and material properties of the slab. This extraordinary acoustic transmission phenomenon holds for any slab thickness, making it analog...

The objectives in this work were to develop, calibrate, and apply a model to predict ideal taper profiles down the narrow faces of the SIDERAR slab casting mold for several different casting speeds, steel grades, flux powder compositions, and widths. A significant amount of original research was undertaken for this challenging problem. A finite difference model of transient 1-D heat conduction ...
