Chloridotris(3,5-dimethyl-1H-pyrazole-κN2)(formato-κO)copper(II)–dichloridobis(3,5-dimethyl-1H-pyrazole-κN2)copper(II) (2/1)

open access: yesActa Crystallographica Section E, 2011
The asymmetric unit of the title compound, [Cu(CHO2)Cl(C5H8N2)3]2·[CuCl2(C5H8N2)2] or 2[A]·[B], contains one A molecule and one half-molecule of B, located on a centre of inversion. The CuII environments in A and B are different.

Computer code to interchange CDS and wave-drag geometry formats [PDF]

open access: yes
A computer program has been developed on the PRIME minicomputer to provide an interface for the passage of aircraft configuration geometry data between the Rockwell Configuration Development System (CDS) and a wireframe geometry format used by ...

Conceptual Issues for Noncommutative Gravity on Algebras and Finite Sets

open access: yes, 1999
We discuss some of the issues to be addressed in arriving at a definitive noncommutative Riemannian geometry that generalises conventional geometry both to the quantum domain and to the discrete domain.

Bis(2-aminopyrimidine-κN1)dibromidozinc(II)

open access: yesActa Crystallographica Section E, 2008
The title compound, [ZnBr2(C4H5N3)2], is a mononuclear complex in which the ZnII ions have distorted tetrahedral coordination geometry. The ZnII ion binds to two N atoms from two different 2-aminopyrimidine ligands and two bromide ions.

Crystal structure of bis[2-(benzothiazol-2-yl)phenolato-κ2N,O]copper(II)

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2015
In the title complex, [Cu(C13H8NOS)2], the CuII atom is coordinated by two N atoms and two O atoms from two bidentate benzothiazolphenolate ligands, forming a distorted tetrahedral geometry [dihedral angle between two N—Cu—O planes: 45.1 (2)°].

Intercusp Geodesics and Cusp Shapes of Fully Augmented Links

open access: yes, 2017
We study the geometry of fully augmented link complements in $S^3$ by looking at their link diagrams. We extend the method introduced by Thistlethwaite and Tsvietkova to fully augmented links and define a system of algebraic equations in terms of ...

Bis(2,2′-bipyridyl)-1κ2N,N′;3κ2N,N′-bis(4-bromo-2-formylphenolato)-1κ2O,O′;3κ2O,O′-bis[μ-2-(5-bromo-2-oxidobenzylideneamino)ethanesulfonato]-1:2κ3O:N,O2;2:3κ3N,O2:O-tricopper(II) monohydrate

open access: yesActa Crystallographica Section E, 2009
The title complex, [Cu3(C9H8BrNO4S)2(C7H4BrO2)2(C10H8N2)2]·H2O, lies on an inversion center located on the central Cu atom, which is four-coordinated in a square-planar geometry, whereas the outer Cu atoms related by symmetry are five ...

DG in DG (Digital grammar in descriptive geometry)

open access: yesEGA, 2019
Nowadays the inclusion of CAD software is well-established in Geometry teaching within the field of Architectural Graphic Expression. In this environment, we suggest the introduction of visual programming software tools which would allow us to focus on ...

On the Effect of Geometries Simplification on Geo-spatial Link Discovery

open access: yesProcedia Computer Science, 2018
Abstract Link discovery is central to the integration and use of data across RDF knowledge bases. Geospatial information is increasingly represented according to the Linked Data principles. Resources within such datasets are described by means of vector geometry, where link discovery approaches have to deal with millions of point sets consisting of ...
