Relating geometry descriptions to its derivatives on the web [PDF]

open access: yes, 2019
Sharing building information over the Web is becoming more popular, leading to advances in describing building models in a Semantic Web context. However, those descriptions lack unified approaches for linking geometry descriptions to building elements ...

Investigation and analysis of the linear dimensions of the flexible manipulator section in the process of tilting [PDF]

open access: yesE3S Web of Conferences, 2023
A feature of the functioning of such a device is a change in the position of each of the sections. The study of the peculiarities of changing the position of the link is an important task.

(3-Hydroxy-2-{[1-(2-oxidophenyl)ethylidene]amino-κ2O,N}propanoato-κO1)diphenyltin(IV)

open access: yesActa Crystallographica Section E, 2010
In the title compound, [Sn(C6H5)2(C11H11NO4)], the tin(IV) atom is penta-coordinated in a distorted trigonal-bipyramidal SnC2NO2 geometry. In the crystal structure, intermolecular O—H...O hydrogen bonds link the molecules into centrosymmetric ...

Link maps and the geometry of their invariants [PDF]

open access: yesManuscripta Mathematica, 1988
The geometry of two types of link homotopy invariants of a link map f:Sp∐Sq→Sm is discussed. The first one is the α-invariant which greatly generalizes the classical notion of linking number. The second one, the β-invariant, is closely related to the linking behaviour of f|sp with only the double point set of f|Sq, and therefore measures (to some ...

Tris(ethylenediamine-κ2N,N′)nickel(II) bis(dimethyl phosphate)

open access: yesActa Crystallographica Section E, 2012
In the title compound, [Ni(C2H8N2)3][O2P(OCH3)2]2, the NiII atom is six-coordinated in a distorted octahedral geometry by six N atoms from three ethylenediamine ligands. The P atoms of the anions adopt a distorted tetrahedral geometry.
