High-Density (HD) Head-related transfer function (HRTF) measurements are extremely timeconsuming and complicated. This problem can be solved by continuously rotate a dummy head and using on-line de-convolution of binaural signals to obtain the HD HRTFs. In this work, we use a generalized frequency-domain adaptive filter (GFDAF) for HD HRTF measurements, which has significant better convergence ...

Distal molar relationships can arise due to the mesiopalatal rotation of maxillary molars. In some cases, an ideal Class I intercuspation can be achieved with the opposing molar and a Class II relationship can be corrected by molar derotation. Maxillary molars consist of three roots and, due to the early loss of the deciduous second molars, the palatal root acts as a hinge for mesial rotation o...

Since in Euclidean and Riemannian continuous smooth geometry a point cannot rotate, it follows then that only a finite length line could rotate. Overlooking this simple evident and trivial point is the cause of most of the troubles associated with the general theory of relativity. Once realized, the situation could be resolved by going in the directions of Cartan-Einstein spacetime but all the ...

An improved moiré deflectometry phase-shifting technique is presented. A squared grating is used to multiplex the information of the deflections in two orthogonal directions in one image. This procedure avoids the need to rotate the gratings to obtain complete deflection information. However, the use of these gratings makes impossible the application of standard phase-shifting algorithms. Speci...

The two dimensional steady state Stokes equations are solved by using a novel MLPG-Mixed Finite Volume method, that is based on the independent meshless interpolations of the deviatoric velocity strain tensor, the volumetric velocity strain tensor, the velocity vector and the pressure. The pressure field directly obtained from this method does not suffer from the malady of checker-board pattern...

We describe a method for 3D reconstruction of plant seed surfaces, focusing on small seeds with diameters as small as 200 μm. The method considers robotized systems allowing single seed handling in order to rotate a single seed in front of a camera. Even though such systems feature high position repeatability, at sub-millimeter object scales, camera pose variations have to be compensated. We do...

The orientation of steel fibers in magnetically driven concrete and magnetically driven mortar was experimentally studied in this paper using a magnetic method. In the magnetically driven concrete, a steel slag was used to replace the coarse aggregate. In the magnetically driven mortar, steel slag and iron sand were used to replace the fine aggregate. A device was established to provide the mag...

INTRODUCTION The ability to mentally rotate an object in 3 dimensions has been shown with an individual's score on the Vandenberg and Kuse Mental Rotations Test. The was to determine whether this Mental Rotations Test could be used to predict performance complex surgical skill - the tying of a 1-handed surgical reef knot. In addition, we learning a spatially complex surgical skill could be achi...
