Φ-value analysis has proved to be a powerful technique in protein folding studies. It has been used to study the transition state structures, to infer microscopic folding pathways, and to identify key residues in the protein folding process. However, its effectiveness in protein binding reaction has not been tested, especially when a fly-casting mechanism is involved. In this article we attempt...

A concept for the casting of metallic fuels pins containing low vapor pressure materials is presented and discussed. The important physics of this concept include the mass transport of americium from the melt, the induction heating and stirring of the melt, plus the casting of long slender fuel rods. This paper discusses and presents preliminary modeling results for the casting of long, slender...

Particle-based computational methods, such as the Smoothed Particle Hydrodynamics (SPH) method, do not require a numerical mesh. Because of the mesh-less characteristics, they are suitable for the numerical simulation of the casting process. In order to optimize the production condition, the simulation of the semi solid casting by the particle method is expected to be applicable. In the semi so...

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...

We consider the problem of dynamic coupling between the rapid thermal solidification and mechanical compression of steel in twin-roll steel strip casting. In traditional steel casting, molten steel is first solidified into thick slabs and then compressed via a series of rollers to create thin sheets of steel. In twin-roll casting, these two processes are combined, thereby making control of the ...

This study commences by performing an experimental investigation to measure the temperature distribution within a casting system comprising a cylindrical aluminum casting and a green-sand mold. The experimental temperature measurements are then used to compute the effective heat transfer coefficient at the mold/metal interface using four different formulae. In the temperature measurement, a sym...

-In this paper a Lagrangean decomposition technique for solving the scheduling problem for Hot Charged Rolling (HCR) in the continuous casting process which involves sequencing and grouping. This Lagrangian relaxation algorithm is proposed that incorporate two sets of constraints into the objective function after applying the variable splitting technique. The relaxed problem has a special struc...

UNLV investigators will evaluate and select a process for the melt casting of metallic fuel pins that contain volatile actinides. This work will be performed with the guidance of Argonne National Laboratory (ANL) engineers to insure that their knowledge and experience benefits the project. The research to be conducted during year one will center on selecting, evaluating, and modeling potential ...

Ray Casting is a direct volume rendering technique for visualizing 3D arrays of sampled data. It has vital applications in medical and biological imaging. Nevertheless, it is inherently open to cluttered classification results. It suffers from overlapping transfer function values and lacks a sufficiently powerful voxel parsing mechanism for object distinction. In this work, we are proposing an ...
