In-Situ Determination of Astro-Comb Calibrator Lines to Better
High precision wavelength calibrators for high-resolution astrophysical spectrographs will be key components of new precision radial velocity (RV) observations including the search for Earth-like exoplanets and direct observation of cosmological deceleration. The astro-comb, a novel high-precision calibrator, is a combination of an octave-spanning femtosecond laser frequency comb and a Fabry-Pé...
متن کاملEyes Draw Auxiliary Lines in Interpreting Images
This study aims at finding a typical pattern in the eye movement, when human obtains an interpretation of a presented image. We conducted experiments where subjects looked at abstract artworks and commercial posters. We compared the eye track lines with subjects’ statements about the interpretation of the image. The results show the tendency that eyes draw lines in the velocity between saccade ...
متن کاملInterpreting bruises at necropsy.
The accurate interpretation of bruising at necropsy is essential to understanding how a victim has been injured and assists the pathologist in a reliable reconstruction of the events leading to death. It is essential not only to assess the mechanism of production of a bruise, taking into account the type of impacting surface and the magnitude of force used, but also to estimate when the injury ...
متن کاملSea£oor slopes at mid-ocean ridges from submersible observations and implications for interpreting geology from sea£oor topography
Observations from 145 submersible dives are used to create a database of mid-ocean ridge scarp topography and lithology. Seafloor lithologies are classified into extrusives, basaltic talus, dykes, gabbros and serpentinites, and the dive locations are broadly classified according to whether they are close to transform valleys and as a function of ridge spreading rate. The database is used to det...
متن کاملLines in higgledy-piggledy position
In this article, we examine sets of lines in PG(d,F) meeting each hyperplane in a generator set of points. We prove that such a set has to contain at least 1.5d lines if the field F has more than 1.5d elements, and at least 2d− 1 lines if the field F is algebraically closed. We show that suitable 2d−1 lines constitute such a set (if |F| ≥ 2d−1), proving that the lower bound is tight over algebr...
