IN A previous paper (FEINSTEIN and WILLIAMS, 1971) the relationship between the horizontal and vertical saccadic systems was examined. Results indicate that the two orthogonal saccadic systems share a common information processing channel. The series of experiments which are discussed in this paper, are intended to investigate the relationship between the horizontal saccadic and the vertical sm...

In recent work, data-driven sweet spotting technique for shale plays previously explored with vertical wells has been proposed. Here, we extend this technique to multiple formations and formalize a general data-driven workflow to facilitate feature extraction from vertical well logs and predictive modeling of horizontal well production. We also develop an experimental framework that facilitates...

We present analog experiments on dike propagation, followed by a numerical model of horizontal and vertical growth, which is partially analytical based empirical observations. Experimental results show that the growth rates are similar until buoyancy becomes significant and, afterward, dominates. The defined for different conditions in homogeneous medium: (a) constant flux, fracture-limited pro...

Abstract In recent years, bio-inspired burrowing robots and other intruder problems in granular media have attracted significant attention. Many of these, especially related to traditional penetration geotechnical engineering, cover vertical penetration. Modelling these types numerically using the discrete element method (DEM) is typically done ignoring gravity by controlling stresses selected ...

Time-of-flight diffraction method (ToFD) is an amplitude-independent sizing method which is based on the measurement of time-of-flight of defect tip diffracted waves. Although ToFD can measure through-wall length of defect accurately, this method is not capable of measuring horizontal defect size. In this paper, a new ToFD method for evaluating horizontal planar defects is presented. The finite...

Purpose. To evaluate the relationship between macular microstructures and visual function in retinitis pigmentosa (RP). Method. Fourier domain optical coherence tomography (FD-OCT) and Goldmann perimetry were used to examine 100 eyes of 100 RP patients. The preserved photoreceptor outer segment (PROS) length was measured at the horizontal and vertical high definition line scans. The PROS area w...

Accurately detection of retinal landmarks, like optic disc, is an important step in the computer aided diagnosis frameworks. This paper presents an efficient method for automatic detection of the optic disc’s center and estimating its boundary. The center and initial diameter of optic disc are estimated by employing an ANN classifier. The ANN classifier employs visual features of vessels and th...

Horizontal dispersion in the surface waters of a medium-sized lake was investigated based on four experiments with ensembles of 14 to 17 drifters deployed in Lake Constance during the winter season. The experiments cover length scales between 30 and 3000 m which are typical for the grid length scales employed in 3-D models. Horizontal dispersion coefficients Kdisp were estimated to range from 0...

All published studies on micrographia, a diminution of letter size, examine handwriting in the horizontal direction. Writing horizontally typically requires increased wrist extension as handwriting progresses from left to right. Chinese characters, however, can be written not only horizontally from left to right, but also vertically from top to bottom. We examined the effect of handwriting dire...
