BURRAU'S PROBLEM OF THREE BODIES [PDF]
Proceedings of the National Academy of Sciences, 1967 initially. The problem treated in this paper is to determine their subsequent motion. Because of the relation of the initial conditions to a Pythagoreani triangle, Burrau's problem may also be referred to as a Pythagorean problem of three bodies. That the motion of the particles takes place in the plane of the triangle is an immediate consequence of ...

A new hybrid finite element approach for three-dimensional elastic problems
Archives of Mechanics, 2012 A new fundamental solution based finite element method (HFS-FEM) is presented for analyzing three-dimensional (3D) elastic problems with body forces in this paper. It begins with deriving formulations of 3D HFS-FEM for elastic problems without body force

Spectrum generating algebra of the symmetric top [PDF]
, 1997 We consider an algebraic treatment of a three-body system. We develop the formalism for a system of three identical objects and show that it provides a simultaneous description of the vibrational and rotational excitations of an oblate symmetric top ...

On a Periodic Solution of the 4-Body Problems
Advances in Mathematical Physics, 2014 We study the necessary and sufficient conditions on the masses for the periodic solution of planar 4-body problems, where three particles locate at the vertices of an equilateral triangle and rotate with constant angular velocity about a resting particle.

Development of a wind-tunnel for spinning body using magnetic suspension
Nihon Kikai Gakkai ronbunshu, 2017 A wind-tunnel system for spinning body has been proposed to measure hydrodynamic forces acting on the body. In the proposed system, the body is suspended and rotated by electromagnets. The forces are measured from the control signal for suspension.

Exact relations for quantum-mechanical few-body and many-body problems with short-range interactions in two and three dimensions [PDF]
, 2012 We derive relations between various observables for N particles with zero-range or short-range interactions, in continuous space or on a lattice, in two or three dimensions, in an arbitrary external potential.

Sex and Rural/Urban Centre Location as Determinants of Body Image Self-Perception in Preschoolers
Children, 2022 Body image and self-perception are highly related to psychological health and social well-being throughout the lifespan. Body image problems can lead to pathologies affecting the quality of life. Thus, it is essential to analyse perceived self-image from

Algebraic treatment of three-body problems
, 1998 We discuss an algebraic treatment of three-body systems in terms of a U(7) spectrum generating algebra. In particular, we develop the formalism for nonlinear configurations and present an algebraic description of vibrational and rotational excitations of
