Simplified selection of optimal shell of revolution

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2019
Relevance. Architects and engineers, designing shells of revolution, use in their projects, as a rule, spherical shells, paraboloids, hyperboloids, and ellipsoids of revolution well proved themselves.

A recursive method for finding revolute-jointed manipulator singularities [PDF]

open access: yesProceedings 1992 IEEE International Conference on Robotics and Automation, 1995
A geometric application of screw theory is used to develop a recursive algorithm for computing all singular configurations of revolute-jointed manipulators with arbitrary link geometries and an arbitrary number of joints. The depth of the recursion is linear in the number of joints, n, while the computational burden is proportional to 2n−2. This method

Application of the finite element method in the calculation of shells of revolution

open access: yesHerald of the Azerbaijan Engineering Academy, 2022
The paper describes an algorithm for calculating structurally orthotropic shells of rotationwith an arbitrary shape of the meridian and an arbitrary law of change in the rigidity of the shellalong the meridian. In this case, a number of restrictions are imposed on the law of change in theshell stiffness.

On the Affine Image of a Rational Surface of Revolution

open access: yesMathematics, 2020
We study the properties of the image of a rational surface of revolution under a nonsingular affine mapping. We prove that this image has a notable property, namely that all the affine normal lines, a concept that appears in the context of affine ...

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

open access: yesFEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be
