Effect of geometry of tank on the thermal characteristics of waxy crude oil during its static cooling

open access: yesCase Studies in Thermal Engineering, 2020
With the purpose of revealing the inner link between the thermal characteristics and geometry of tank, the physical and mathematical models of waxy crude oil during static cooling process under different geometric sizes are established. Based on the data

Numerical study on the behavior of link-to-column connections in eccentrically braced frames [PDF]

open access: yesNumerical Methods in Civil Engineering, 2014
Geometry of eccentrically braced frames (EBFs) in some cases causes the connection of link beam to the column. The details of such conditions should be studied carefully due to the full plastic rotation in the link beam. In this research, the behavior of

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.

Geometry of alternating links on surfaces

open access: yesTransactions of the American Mathematical Society, 2020
We consider links that are alternating on surfaces embedded in a compact 3-manifold. We show that under mild restrictions, the complement of the link decomposes into simpler pieces, generalising the polyhedral decomposition of alternating links of Menasco.

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.
