Covering the Plane with Translates of a Triangle [PDF]

open access: yesDiscrete & Computational Geometry, 2009
The author proves that the minimum density of a covering of the plane by translates of a triangle is 3/2. This establishes that triangles are the least economical sets for translative plane covering.

Translation complements of C-planes: (IV) [PDF]

open access: yesManuscripta Mathematica, 1987
Narayana Rao, Rodabaugh, Wilke and Zemmer constructed a new class of finite translation planes from exceptional near-fields described by Dickson and Zassenhaus. These planes referred to as C-planes are not coordinatized by the generalized André systems. In this paper we compute the translation complement of the C-plane corresponding to the C-system III–

A EUCLIDEAN FORMULATION OF INTERIOR ORIENTATION COSTRAINTS IMPOSED BY THE FUNDAMENTAL MATRIX [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
Epipolar geometry of a stereopair can be expressed either in 3D, as the relative orientation (i.e. translation and rotation) of two bundles of optical rays in case of calibrated cameras or, in case of unclalibrated cameras, in 2D as the position of the ...

Ethyl N-(2-acetyl-3-oxo-1-phenylbutyl)carbamate

open access: yesActa Crystallographica Section E, 2013
In the title compound, C15H19NO4, all three carbonyl groups are syn-oriented with respect to the methine group attached to the phenyl ring. The mean planes of the phenyl ring and ethyl carbamate moiety form a dihedral angle of 65.2 (1)°.

Feasibility and Preliminary Efficacy of Integrative Neuromuscular Training for Childhood Cancer Survivors: A Pilot Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of childhood acute lymphoblastic leukemia (ALL) often exhibit early deficits in muscle and movement competence, which can compromise long‐term health. Integrative neuromuscular training (INT), a multifaceted approach combining fundamental movement activities with strength exercises, may help address these deficits during ...

Two View Line-Based Motion and Structure Estimation for Planar Scenes

open access: yesELCVIA Electronic Letters on Computer Vision and Image Analysis, 2012
We present an algorithm for reconstruction of piece-wise planar scenes from only two views and based on minimum line correspondences. We first recover camera rotation by matching vanishing points based on the methods already exist in the literature and ...
