Many scienti c and engineering disciplines, through physical measurements or computational simulations, generate large scale three-dimensional data sets. Both the physical size and the computational resources needed to render these data sets present a challenge to current rendering architectures and techniques. The Fujitsu AP1000 has the memory capacity and the processing speed to render large ...

the aim of conducting this research was to evaluate the viscosity change in the continuous casting of steel moldpowders by altering their chemical compositions, using hot stage microscope analysis. 4 low-fluorine samplescontaining such compositions as mno, fe2o3, li2o, tio2 and zno, as well as another fluorine-free samplecontaining a combination of fe2o3 and tio2, were prepared in this research...

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 ...

This paper presents a novel method to accelerate volume ray casting as used in virtual colonoscopy. The method exploits a pre-processing visibility technique to identify the potentially visible portions of the colon. Then it applies a space leaping technique based on the projection of the visible boundary voxels of the colon onto the image plane. The method has been tested using a synthetic dat...

The paper focuses on the research of influence chosen technological parameters die casting selected mechanical properties castings based Al-Si alloys. experiments conducted within frame practical part examined plunger pressing speed in mould cavity influencing a which were represented by ultimate tensile strength and percentage share porosity castings. Plunger is closely related to filling mode...

Subsurface hook formation during initial solidification in the continuous casting mould degrades the quality of steel slabs owing to the associated entrapment of argon bubbles and non-metallic inclusions. To minimise hook depth and to improve slab quality, extensive plant experiments were performed and analysed to quantify the effect of casting parameters on hook characteristics using the no. 2...

The aim of this work was WC distribution in base Al-Si-Mg (A356) alloy as reinforcing agent. WC Solid particles in the sub-23-nm size range added to melted alloy by centrifuge casting. The cylinder tube without gap was obtained. FESEM and OPM results show that the distribution depends upon the rotational speeds of the mould and centrifugal casting conditions. According to the MAP results, durin...

Accurate determination of the position of final solidification point or crater end at ArcelorMittal Dofasco’s No. 2 Continuous Caster (CC) is essential for maximizing both casting speed and equipment utilization. The caster is equipped with one 900-mm long, straight, water-cooled copper mold, and produces 218-mm thick slabs with a maximum width of ~1,600 mm. The casting speed range at the caste...

Lazy Sweep Ray Casting is a fast algorithm for rendering general irregular grids. It is based on the sweep-plane paradigm, and it is able to accelerate ray casting for rendering irregular grids, including disconnected and nonconvex (even with holes) unstructured irregular grids with a rendering cost that decreases as the “disconnectedness” decreases. The algorithm is carefully tailored to explo...
