Situated Near Channel Bottoms
Identification algorithms are considered for a class of targets situated near the bottom of a water channel. It is assumed that the target-sensor distance relative to the channel depth is such that a ray-based representation of the scattered fields is appropriate (vis-à-vis a modal representation). Two approaches are considered for processing the scattered fields. In one algorithm a deconvoluti...
متن کاملExtinction, Slime, and Bottoms
Open access, freely available online T here is an old Chinese curse: 'May you live in interesting times.' According to those who know about such things, we live in a momentous time, the time of the Sixth Mass Extinction! But most of us do not feel at all cursed. Because, in fact, the Sixth is quite different to the previous Big Five—no-one would notice this one if we were not repeatedly reminde...
متن کاملEffects of optically shallow bottoms on upwelling radiances: Inhomogeneous and sloping bottoms
If the benthic boundary in optically shallow waters is spatially inhomogeneous or sloping, the underwater light field is inherently three-dimensional (3D). Numerical simulations of 3D underwater radiances were made for environmental conditions observed in shallow Bahamian waters. The simulations show that if the pattern of bottom reflectance for an inhomogeneous but level bottom has a spatial s...
متن کاملDream incubation: ancient techniques of dream influence
Dream incubation refers collectively to the practices, rituals, techniques and efforts that an individual applies to intentionally evoke helpful dreams. Derived from the Latin verb incubare (in'upon' + cubare 'to lie'), the term connotes the support and nurturance provided by a laying mother bird for her developing egg. The parallels with dream influence are all too appropriate; in antiquity, t...
متن کاملFrom Paraphrase Database to Compositional Paraphrase Model and Back
The Paraphrase Database (PPDB; Ganitkevitch et al., 2013) is an extensive semantic resource, consisting of a list of phrase pairs with (heuristic) confidence estimates. However, it is still unclear how it can best be used, due to the heuristic nature of the confidences and its necessarily incomplete coverage. We propose models to leverage the phrase pairs from the PPDB to build parametric parap...
