We present an integrated approach for real-time performance prediction of volume raycasting that we employ for load balancing and sampling resolution tuning. In volume rendering, the usage of acceleration techniques such as empty space skipping and early ray termination, among others, can cause significant variations in rendering performance when users adjust the camera configuration or transfe...

There are many situations in which mis-coordinated strategic voting can leave strategic voters worse off than they would have been had they not tried to strategize. We analyse the simplest of such scenarios, in which the set of strategic voters all have the same sincere preferences and all cast the same strategic vote, while all other voters vote sincerely. Most mis-coordinations in this framew...

We propose that voting protocols be judged in part on ballot casting assurance, a property which complements universal verifiability. Some protocols already support ballot casting assurance, though the concept has not received adequate explicit emphasis. Ballot casting assurance captures two well known voting concepts – cast as intended, and recorded as cast – into one end-to-end property: Alic...

This work has been motivated by some issues of process monitoring in casting applications. In die casting, as time passes, material is deposited on the inside wall of the die. This foreign material can cause an unacceptable level of porosity in the output of the casting process. After accumulated material reaches a certain level, some of the output of the casting process no longer meets the spe...

To quantify the influence of temperature uncertainty on thermal fatigue life prediction a shot sleeve in an injection mechanism, analysis method based Kriging surrogate model and Monte Carlo simulation (MCS) was proposed. The training samples were obtained by finite element simulation, response relationships between input variables, such as pouring preheating temperature, target strain stress, ...

Present chemical-physical characteristics of ingot and continuous casting powders can be critically evaluated pointing out history of invention of these materials. In an original tone, pioneering nature of first developments of casting powders will be described, illustrating empirical know-how of casting powders technology, based on trial-and-error method. It will be originally emphasized that ...
