New Method for Opacity Correction in Oversampled Volume Ray Casting
A new opacity correction approach for oversampled volume ray casting is introduced. While the only existing opacity correction method in the literature is based on the assumption of dataset homogeneity, the new opacity correction method introduced in this paper is a faster, generalized voxel-by-voxel approach which does not assume dataset homogeneity. The new opacity correction avoids the datas...
متن کاملOpacity Testing
Opacity testing is formalized and studied. We specify opacity testers as well as tested systems by (timed) process algebras. We model various testers according to how sophisticated observations of tested system they can make and which kind of conclusions they can obtain. We use this technique to define several realistic security properties. The properties are studied and compared with other sec...
متن کاملDecomposing Opacity
Transactional memory (TM) algorithms are subtle and the TM correctness conditions are intricate. Decomposition of the correctness condition can bring modularity to TM algorithm design and verification. We present a decomposition of opacity called markability as a conjunction of separate intuitive invariants. We prove the equivalence of opacity and markability. The proofs of markability of TM al...
متن کاملRational Opacity
A key motivation for transparency regulations and disclosure rules is the view that corporations are more opaque than they could be. Traditional arguments attribute this tendency to agency problems between managers on one side and stakeholders and/or outsiders on the other. We propose a completely di erent argument for why corporations limit the ow of information. When secondary markets are sha...
متن کاملOpacity in Tundra Nenets
The analysis of opaque relations presents a problem to classic Optimality Theory (OT) (Prince and Smolensky 1993, McCarthy and Prince 1993), inherently a surface-oriented theory. Many different proposals have been made to integrate the analysis of opacity into OT. In this paper, we address the problem of opacity in Tundra Nenets (TN), a Uralic (Samoyedic) language spoken in Arctic Russia and No...
