The Madagascar sea elevation dataset presents a problem where data are collected along crossing tracks. These tracks are not straight, and are therefore irregular in the model space. Previous methods assumed that the data were regularly sampled in the model space coordinate system, or did not take into account the regularities in the acquisition of the data. Instead of attempting to find a pred...

For about twenty years the standard color sampling method for RGBA volume data has been the interpolation of opacity-weighted colors. In this work, we discuss the underlying approximations and derive an improved sampling method, which avoids some of these approximations. With the help of several examples and experiments we demonstrate that our new technique is in fact preferable for direct volu...

Decision theory requires agents to assign probabilities states of the world and utilities possible outcomes different actions. When commit having and/or in a decision problem defined by objective features world, they may find themselves unable decide which actions maximize expected utility. has long recognized that work-around strategies are available special cases; this is where dominance reas...

Interpolation and prediction of spatiotemporal data are integral components of many real-world applications. Thus, approaches of interpolating and predicting spatiotemporal data have been extensively investigated. Currently, the grey dynamic model has been used to enhance the performance of interpolating and predicting spatiotemporal data. Meanwhile, the Extensible Markup Language (XML) has uni...
