The haptic perception of vertical, horizontal, +45 degrees-oblique, and +135 degrees-oblique orientations was studied in adults. The purpose was to establish whether the gravitational cues provided by the scanning arm-hand system were involved in the haptic oblique effect (lower performances in oblique orientations than in vertical-horizontal ones) and more generally in the haptic coding of ori...

Since hydraulic fractures exhibit a strong tendency to propagate in a plane normal to the least principal stress, the preferred plane of propagation under thrust stress regime (Sh > Sv) conditions is horizontal. This can lead to complications in applying the hydrofracture stress measurement technique as horizontal fractures do not directly sample the horizontal stress field. Recent experiences ...

Nuclear area and orientation in the subventricular and intermediate zones was studied quantitatively in coronal vs. sagittal sections of the dorsomedial neocortex. Nissl-stained methacrylate-embedded normal rat embryos were studied between embryonic days (E) 13 and E22. The area of nuclear profiles and the degrees their long axes (defined as a straight line through the two most distant points i...

We report new experimental results which suggest that the generation of extreme wave events in the Faraday surface ripples is related to the increase in the horizontal mobility of oscillating solitons (oscillons). The analysis of the oscillon trajectories in a horizontal plane shows that at higher vertical acceleration, oscillons move chaotically, merge and form enclosed areas on the water surf...

This paper proposes a method to reproduce the Head Related Transfer Function (HRTF) in the horizontal auditory scene. The method is based on a separable representation which consists of a Fourier Bessel series expansion for the spectral components and a conventional Fourier series expansion for the spatial dependence. The proposed representation can be used to predict HRTFs at any azimuth posit...

Since Kunihiro Nagahara’s original presentation at the 1993 ASCRS meeting, several different variations of chopping have evolved. Conceptually these can be divided into two main categories. I call the classic Nagahara technique horizontal chopping, because the instrument tips move toward each other in the horizontal plane during the chop. In vertical chopping, the two instrument tips move towar...

When a thin sheet of a flexible material such as paper is fed from a horizontal spool towards a rough horizontal plane below it, the sheet folds on itself in a regular manner. We model this phenomenon as a free boundary problem for a nonlinearly elastic sheet, taking into account the stiffness and weight of the sheet and the height of the spool above the plane. By using a continuation scheme we...

Horizontal and sagittal dipole layer distributions were estimated from scalp electroencephalogram for three dimensional dipole imaging of brain electrical activity. Horizontal dipole layer being parallel to the brain surface has been used in previous head models. In the present study, the dipole layer distribution in the sagittal plane was also introduced to identify the position of dipole sour...

We investigated the speech intelligibility differences of normal and bone-conduction stereo headphones of target speech localized at 45◦ on the horizontal plane when competing noise is present. This was our effort to study the possible effect of crosstalk found in bone-conduction headphones on speech intelligibility. All sound sources were localized on the horizontal plane. Target speech was lo...

Free convection cooling of isothermal circular cylinders positioned above a horizontal plane is investigated numerically, using a commercial Computational Fluid Dynamics (CFD) software package. Computation is performed for high Rayleigh number, in the range 10 − 10. Chien’s turbulence model of low-Reynolds-number K-ε is used, with Prandtl number of 0.707, corresponding to air near standard cond...
