The satiation theory of ambiguous figures holds that interpretation shifts are caused by fatigue of neural arrangements responsible for the prevailing interpretation. A four-state multistable figure is introduced, in which two depicted cubes can be seen as connected or unconnected and as facing up or facing down. Observers viewed the figure for 4 min. When(More)
Results are presented from a posteriori evaluations of momentum and energy transfer between the resolved and subgrid scales when the multifractal subgrid-scale model from Part I is implemented in a flow solver for large-eddy simulations of turbulent flows. The multifractal subgrid-stress model is used to evaluate the subgrid part ij * of the stress tensor,(More)
Results are presented from a new approach to modeling the subgrid-scale stresses in large-eddy simulation of turbulent flows, based on explicit evaluation of the subgrid velocity components from a multifractal representation of the subgrid vorticity field. The approach is motivated by prior studies showing that the enstrophy field exhibits multifractal(More)
The author investigated the possibility that nonvisual locomotion with a cane depends on the sound of the cane tapping. Blindfolded participants were asked to judge whether a gap in front of them could be crossed by walking. An acoustic analysis suggested that sound could, in theory, distinguish the gaps. Blindfolded sighted participants in Experiments 1(More)
We report a study of 3,3-dimethyl substituted acylthioureas. X ray data and quantum mechanical calculations demonstrated that the "S" conformation is the most stable both for the acylthioureas and the corresponding anions. The high regioselectivity towards S-alkylation is explained on the basis of the localization of the HOMO mainly over the sulfur atom.(More)
The talk will discuss the fundamental shift in turbulence-modeling paradigm represented by the Nonlinear LES (nLES) method. The method represents a “return-to-first-principles” in turbulence simulation, in that the artificial-viscosity paradigm, used by most turbulence models of the past half-century, is replaced by direct solution of the nonlinear terms in(More)
