Texture-based methods have proven to be useful in the detection of salt bodies in seismic data. In this abstract, we present three computationally inexpensive texture attributes that strongly differentiate salt bodies from other geological formations. The proposed method combines the three texture attributes along with region boundary smoothing for delineating salt boundaries. Our first propose...

Four experiments involving 123 university students tested directionality effects in the comprehension of spatial relations, quantified statements, and propositional connectives with a sentence-picture verification task. Presentation of the referents of terms in the statements was separated by 1 s, and presentation order was congruent or incongruent with the order of terms in the statement. Some...

The focus of this study is to improve the light extraction efficiency and directionality of the OLED using a photonic crystal. First, the single period dielectric structure was optimized for red, green and blue wavelengths. The results showed an increase in directionality to an angle of approximately ± 15 degrees. This is promising since the angle needed for comfortable viewing is considered to...

The effects of handedness on directionality in drawing are already well documented in the literature, at least as far as adults are concerned. The present study investigates the impact of manual preference on directionality as seen in the drawing product and drawing process, from a developmental point of view. A total of 120 children aged 5 to 9, both right and left-handed drawers, volunteered ...

In nature, protein subunits on the capsids of many icosahedral viruses form rotational patterns, and mathematicians also incorporate asymmetric patterns into faces of polyhedra. Chemists have constructed molecular polyhedra with vacant or highly symmetric faces, but very little is known about constructing polyhedra with asymmetric faces. Here we report a strategy to embellish a C3h truxene unit...

All existing video conferencing systems which support more than two sites and more than one user at each site suffer from directional ambiguity: not only is it generally impossible for two remote users to look each other in the eyes, but even just horizontal directionality is not preserved. Under horizontal directionality we understand that the direction of the users’ gaze or pointing fingers d...
