In the structure Key Holder of the title compound, C2H10N22+·C8H2Cl2O42−, the dications and dianions form hydrogen-bonded ribbon substructures which enclose conjoint cyclic R21(7), R12(7) and R42(8) associations and extend down the c-axis direction.These ribbons inter-associate down b, giving a two-dimensional sheet structure.In
Analytical modeling of cross-ply cylindrical composite submersible shell with elastic buckling using first order shear deformation theory
The main objective of this study is to design composite shells i.e.long, short, thin and thick for the different underwater applications.These shells can be a part of pressure hulls, underwater Oolong Tea vehicles, pressurized tanks, underwater cables and underwater pipelines etc.This paper presents comprehensive procedures for the mathematical mod
SELF-ASSEMBLED ROV AND PHOTOGRAMMETRIC SURVEYS WITH LOW COST TECHNIQUES
In last years, ROVs, have been employed to explore underwater environments and have played an important role for documentation and surveys in different fields of HBS scientific application.In 2017, the Laboratorio di Fotogrammetria of Iuav University of Venice has decided to buy an OpenRov, a low cost ROV that could be assembled by ourselves to add
