A Constitutive Friction Law for Sheet-Bulk Metal Forming
Tribology Online, 2016 Friction has a significant effect on metal forming both in economic and technical terms. This is especially true for sheet-bulk metal forming, which is a combination of bulk metal forming and sheet metal forming.

Dual XH–π Interaction of Hexafluoroisopropanol with Arenes
Molecules, 2021 The dual XH (OH and CH) hydrogen-bond-donating property of 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) and the strong dual XH–π interaction with arenes were firstly disclosed by theoretical studies. Here, the high accuracy post-Hartree–Fock methods, CCSD(T)/

Satellite Orbit Perturbations in Vector Form [PDF]
Nature, 1961 THE first-order perturbation theory of satellite orbits can be formulated simply and elegantly in terms of constants of the unperturbed motion using vector methods. For let the equation of motion be: where μ = GM (M = mass of the earth), and F is a general perturbing force (per ...

Orbits of monomials and factorization into products of linear forms
CoRR, 2018 This paper is devoted to the factorization of multivariate polynomials into products of linear forms, a problem which has applications to differential algebra, to the resolution of systems of polynomial equations and to Waring decomposition (i.e., decomposition in sums of d-th powers of linear forms; this problem is also known as symmetric tensor ...

Satellites’ orbital stability through normal forms
Proceedings of the International Astronomical Union, 2019 AbstractA powerful tool to investigate the stability of the orbits of natural and artificial bodies is represented by perturbation theory, which allows one to provide normal form estimates for nearly-integrable problems in Celestial Mechanics. In particular, we consider the orbital stability of point-mass satellites moving around the Earth.

Orbital angular momentum conservation in Brillouin light scattering within a ferromagnetic sphere
New Journal of Physics, 2018 Magnetostatic modes supported by a ferromagnetic sphere have been known as the Walker modes, each of which possesses an orbital angular momentum as well as a spin angular momentum along a static magnetic field.

Vector Fields and Differential Forms on the Orbit Space of a Proper Action [PDF]
Axioms, 2021 In this paper, we study differential forms and vector fields on the orbit space of a proper action of a Lie group on a smooth manifold, defining them as multilinear maps on the generators of infinitesimal diffeomorphisms, respectively. This yields an intrinsic view of vector fields and differential forms on the orbit space.
