We introduce an approach for solving the incompressible Navier-Stokes equations on a forest of Octree grids in parallel environment. The methodology uses p4est library Burstedde et al.

There are many situations in which two or more agents (e.g., human or computer decision makers) interact with each other repeatedly in settings that can be modeled as repeated stochastic games. In such situations, each agent’s performance may depend greatly on how well it can predict the other agents’ preferences and behavior. For use in making such predictions, we adapt and extend the Social V...

Past uses of octrees have been for representation of static objects. We discuss extensions necessary to model dynamic surfaces. One particularly important aspect of this is the ability to represent expanding surfaces that grow to be arbitrarily large. Our enhanced octree does exactly this, and models contraction as well. The ability to represent dynamic surfaces allows us to apply octrees to ne...

This paper presents an empirical study of the accuracy of multipole expansions of Helmholtz-like kernels with complex wavenumbers of the form k = (α + iβ )θ , with α = 0,±1 and β > 0, which, the paucity of available studies notwithstanding, arise for a wealth of different physical problems. It is suggested that a simple point-wise error indicator can provide an a-priori indication on the number...

This study examines the extent to which word recognition is influenced by the information of grammatical gender given by the French singular definite article (le/la). More specifically, the focus is on auditory word recognition when words are in the final noun phrase in a Subject Verb Object (SVO) sentence. We compared the gender effect with that of the semantic information of the verb in order...
