a full scale physical model of a thin slab caster with a four-hole design submerged entry nozzle (sen) was constructed. on the basis of the dimensionless reynolds and froude similitude criteria, the fluid flow in a full-scale model is similar to that of the actual system and, hence, the data obtained from the water model can be applied to the actual system. in order to determine the optimum ope...

Cold, subducted lithosphere has relatively fast seismic velocity which leads to early arrivals for some vent-station paths. The effect is very large for events in the Tonga-Kermadec ep seismic zone recorded at certain New Zealand stations. These particular arrivals are very high-frequency (3 Hz or greater) and sometimes r emble two distinct phases, the later arrival appearing at about the time ...

We develop a novel way to fabricate subwavelength nanostructures on the freestanding GaN slab using a GaN-on-silicon system by combining self-assemble technique and backside thinning method. Silicon substrate beneath the GaN slab is removed by bulk silicon micromachining, generating the freestanding GaN slab and eliminating silicon absorption of the emitted light. Fast atom beam (FAB) etching i...

Thin slab casting and rolling was originally developed as a low cost alternative to a conventional casting and rolling process route. However, due to the technological restrictions of the first generation plants, only limited quality and productivity goals could be achieved, questioning its further application to more advanced applications. This paper describes the original contributions that D...

may be important locally, but they do not represent a dominant global pattern. Additionally, we have not evaluated the possible effects of 3D slab morphology on trench-parallel flow in the wedge (e.g., 26) or beneath the slab (14, 27). Such flow is likely important locally andmay serve to strengthen or otherwise modulate the trench-parallel flow induced by trench migration. Our model essentiall...

New processes have been developed in the last years to produce near net shape steel products by continuous casting. This work deals with the analysis of the effects of liquid core reduction during the solidification in the microstructure of thin slabs obtained by continuous cast process. An equipment able to simulate the liquid core reduction during the solidification was projected and construc...

We study the far-field reflected diffraction pattern of an index discontinuity in a thin one-dimensional slab illuminated by a plane wave and show that a time-saving modeling technique based on plane wave expansion approaches fairly well the Maxwell-based rigorous models. This method is simple to implement, and it furthermore allows a good understanding of the optical phenomena involved in the ...

We present a three-dimensional finite-difference time-domain analysis of localized defect modes in an optically thin dielectric slab that is patterned with a two-dimensional array of air holes. The symmetry, quality factor, and radiation pattern of the defect modes and their dependence on the slab thickness are investigated. © 1999 Optical Society of America [S0740-3224(99)01302-8] OCIS codes: ...

S U M M A R Y Rapid changes in slab geometry are typically associated with fragmentation of the subducted plate; however, continuous curvature of the slab is also possible. The transition from flat to normal subduction in southern Peru is one such geometrical change. The morphology of the subducted Nazca Plate along this transition is explored using intraslab earthquakes recorded by temporary r...
