How a colloidal paste flows
We have developed a novel computational scheme that allows direct numerical simulation of the mechanical behavior of sticky granular matter under stress. We present here the general method, with particular emphasis on the particle features at the nanometric scale. It is demonstrated that, although sticky granular material is quite complex and is a good example of a challenging computational pro...
متن کاملCastability and surface hardness of titanium cast plates obtained from experimental phosphate-bonded silica investment molds.
The effect of 12 different experimental compositions of phosphate-bonded SiO2 investments was examined on cast pure titanium. The mold temperature was 600 degrees C and the casting was conducted with an argon-arc melting and pressure casting machine. Castability was evaluated by the volume of casting porosity, which was calculated from the volume of wax pattern (15 mm x 15 mm x 1.5 mm), the wei...
متن کاملMICROSTRUCTURE AND PROPERTIES OF COLLOIDAL SILICA BONDED MAGNESITE CASTABLE REFRACTORIES
Abstract: Efforts have been carried out in order to use microsilica to develop a forsterite bond rather than other types of binders in the basic refractory castables. According to the higher drying rate and sinterability of colloidal silica, it has been proposed in the recent years. In the present work, effects of replacement of microsilica by colloidal silica evolution of forsterite bond have ...
متن کاملCut-&-Paste Attacks with JAVA
This paper describes malicious applets that use Java’s sophisticated graphic features to rectify the browser’s padlock area and cover the address bar with a false https domain name. The attack was successfully tested on Netscape’s Navigator and Microsoft’s Internet Explorer; we consequently recommend to neutralize Java whenever funds or private data transit via these browsers and patch the flaw...
متن کاملCopy and paste redeemed
Software development relies critically on code reuse, which software engineers typically realise through handwritten abstractions, such as functions, methods, or classes. However, such abstractions can be challenging to develop and maintain. One alternative form of re-use is copy-paste-modify, a methodology in which developers explicitly duplicate source code to adapt the duplicate for a new pu...
