This note summarizes relevant approximations based on permanent waterplane characteristics for a more accurate assessment of the effects of longitudinal deflections of an elastic ship's hull on drafts and displacement during marine surveys of merchant ships. The possibility of a different practice for placement of draft marks alongside a ship, ensuring the same precision in displacement assessm...

A topographic mapping of angular whisker deflections has recently been discovered in the barrel cortex of rats (Andermann & Moore, 2006). Characteristics of this map suggest that it could emerge in post-natal development, through self-organisation under a Hebbian learning regime. This hypothesis was implemented in a self-organising computational model, from which a remarkably similar mapping em...

An 83-year-old man underwent electrophysiological testing for focal atrial tachycardia (AT) exhibiting narrow P waves with negative deflections in the inferior leads. Catheter ablation at the cavo-tricuspid isthmus (CTI) successfully eliminated the AT. The propagation map during AT and pacing study from the successful ablation site demonstrated that the atrial activation throughout the CTI did ...

Microcantilever-based sensors can be used to detect molecular absorption of, for example, hydrogen gas, which causes changes in the surface stress, leading to deflection of the cantilever. Such a deflection can be determined by means of optical beam deflection, capacitance-, or piezo-resistance based readout. We have recently proposed a compact integrated mechano-optical sensor using a novel an...

In this paper, we introduce a practical modeling approach to improve the quality of polygonal mesh structures. Our approach is based on a discrete version of Gaussian-Bonnet theorem on piecewise planar manifold meshes and vertex angle deflections that determines local geometric behavior. Based on discrete GaussianBonnet theorem, summation of angle deflections of all vertices is independent of m...

The ability of rats to use their whiskers for fine tactile discrimination rivals that of humans using their fingertips. Rats perform discriminations rapidly and accurately while palpating the environment with their whiskers. This suggests that whisker deflections produce a robust and reliable neural code. Whisker primary afferents respond with highly reproducible temporal spike patterns to tran...

The backcalculation of pavement layer moduli from Falling Weight Deflectometer (FWD) measured surface deflections is a challenging task. It can also be formulated as a global optimization problem with the objective of finding the optimal pavement layer moduli values that minimize the error between measured and computed surface deflections. Over the years, several backcalculation methodologies h...

1. Glass microelectrodes were used to record extracellular responses from 308 SI cortical neurons to deflections of the contralateral vibrissae in 21 unanesthetized, paralyzed rats. Controlled deflections of individual hairs were produced by means of an electromechanical stimulator. Fast green dye marks were made to aid histological reconstructions of electrode tracks. 2. TS) were observed thro...

Visually evoked potentials and background EEGs in the cerebral visual, somatosensory, and association areas (lateral suprasylvian gyrus), as well as in the lateral geniculate body (GL) and mesencephalic reticular formation were studied before and after unilateral destruction of the GL of unanes-thetized cat. Autocorrelograms and power spectra of background EEGs in various areas mainly showed ac...
