The plane strain deformation of an isotropic, homogeneous, poroelastic medium caused by an inclined line-load is studied using the Biot linearized theory for fluid saturated porous materials. The analytical expressions for the displacements and stresses in the medium are obtained by applying suitable boundary conditions. The solutions are obtained analytically for the limiting case of undrained...

This paper reports the first application of a new technique to measure the β-decay half lives of exotic nuclei in complex background conditions. Since standard tools were not adapted to extract the relevant information, a new analysis method was developed. The time distribution of background events is established by recording time correlations in backward time. The β half lives of the nuclides ...

The present study examined the spatial distribution of involuntary attentional capture over the two visual hemi-fields. A new experiment, and an analysis of three previous experiments showed that distractors in the left visual field that matched a sought-for target in color produced a much larger capture effect than identical distractors in the right visual field, revealing a visual field asymm...

An important variant of the traditional line bisection task has involved a mechanical device invented by Bisiach and his colleagues (Bisiach et al. Perceptual and premotor factors of unilateral neglect. Neurology 1990;40:1278-81 [3]). This tool was devised to dissociate motor from perceptual factors in hemi-spatial neglect, by means of a mid-line indicator which moved 'congruently' or 'non-cong...

It is widely accepted that the maturation of the extrastriate cortex is not completed before late puberty. To gain insight into the functionality of the extrastriate cortex during normal development, we tested a group of 21 children (age 6-16 years) on their ability to detect motion-defined forms. With a two-alternative forced-choice procedures we determined thresholds and visual half-field asy...

Fourteen pilots flew a synthetic vision system (SVS) display, through a terrain and traffic-rich environment in a high fidelity flight simulator. Traffic information was hosted on the SVS display. In a 2x2 factorial design, the SVS display hosted a highway-in-the-sky in half the conditions, and hosted an instrument panel overlay in the other half. We examined the effects of the resulting clutte...

background the incidence and mortality rates of breast cancer are high among filipino women. the lack of knowledge on preventive behavior and early detection related to breast cancer is considered a reason. conclusions women who were aware of risk factors for breast cancer possessed a higher education level and had knowledge of the association of risk factors with preventive behaviors and early...

This thesis is devoted to the anisotropic edge detection and the anisotropic diffusion in images. Based on Gaussian half filters, these half filters scan all orientations around a pixel with a defined step. From oriented derivatives of Gaussian half filters, an approach to edge detection in color images has been developed. Since the filter is long and thin, this method allows to extract anisotr...
