In this study, corrosion behaviour of A356-10 vol.% SiC composites casted by gravity and squeeze casting is evaluated. For this purpose, prepared samples were immersed in HCl solution for 1h at open circuit potential. Tafel polarization and electrochemical impedance spectroscopy (EIS) were carried out to study the corrosion resistance of composites. The Tafel polarization and EIS studies of ...

We present a novel approach for visualizing the positional and geometrical variability of isosurfaces in uncertain 3D scalar fields. Our approach extends recent work by Pöthkow and Hege [PH10] in that it accounts for correlations in the data to determine more reliable isosurface crossing probabilities. We introduce an incremental updatescheme that allows integrating the probability computation ...

In this paper authors present their new proposition of system for cognitive analysis of dynamic computer tomography perfusion maps (dpCT). The novel contribution of this article is introducing an augmented reality visualization module that supports real time volume rendering (VR) of derived data. Authors also presents the results of their researches on optimization of VR algorithm memory usage ...

Template-based volume rendering is an acceleration technique for volume ray casting. It does not trade-off the image quality for the rendering speed. However it is still fall short of interactive manipulation of volume data, mainly due to the ray-by-ray volume access pattern and the long ray path in the transparent regions. In this paper, we present an object-order template-based volume renderi...

This study takes a look at different DRR generation methods for use in intensity based 2D/3D Image Registration. A specific emphasis is placed on whether the methods are trivially parallelisable with the aim to take advantage of hardware systems with more than one CPU. The ray casting algorithm and light field rendering are found to be suitable for this purpose. A discussion on the parallelisat...

Shrinkage defect in an alloy steel casting for marine engine cylinder cover was estimated by numerical analysis with reference to casting variables such as riser and chiller. Retained melt modulus was employed as a prediction parameter in this study. Shrinkage defects were developed at the final solidification region. This is associated with hot spots, which could be controlled more effectively...

Continuous casting is used to solidify most of the 750 million tons of steel produced in the world every year. Like most commercial processes, continuous casting involves many complex interacting phenomena. Most previous advances have been based on empirical knowledge gained from experimentation with the process. To further optimize the design and improve the continuous casting process, mathema...
