Classification of space-like translation surfaces in the 3-dimensional Lorentz Heisenberg group H3 [PDF]
Purpose – In the Lorentz Heisenberg space H3 endowed with flat metric g3, a translation surface is parametrized by r(x, y) = γ1(x)*γ2(y), where γ1 and γ2 are two planar curves lying in planes, which are not orthogonal.

Coplanar Repeats by Energy Minimization [PDF]
This paper proposes an automated method to detect, group and rectify arbitrarily-arranged coplanar repeated elements via energy minimization. The proposed energy functional combines several features that model how planes with coplanar repeats are ...

Translation planes of odd order and odd dimension
The author considers one of the main problems in finite translation planes to be the identification of the abstract groups which can act as collineation groups and how those groups can act.

Surface Reconstruction Adopting Laser Plane of Linear Path System Registered by Parallel Constraint
A surface reconstruction technology, which is contributed from the parallel constraint between two laser planes, is introduced and achieved by a laser projector guided by a linear path system.

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

Maximal equicontinuous factors and cohomology for tiling spaces [PDF]
We study the homomorphism induced on cohomology by the maximal equicontinuous factor map of a tiling space. We will see that this map is injective in degree one and has torsion free cokernel.
