A fast quadrature-based gravity model for the homogeneous polyhedron [PDF]

Monthly Notices of the Royal Astronomical Society, 2019
ABSTRACT To date several probes have been sent to explore the Solar system’s asteroids and comets. These bodies are often irregular in shape and to safely navigate probes in their vicinity accurate gravity models are required. For an arbitrarily shaped constant-density body, the gravitational field can be determined from the surface ...

A Spherical Motor Driven by Electro-Magnets Based on Polyhedrons

International Journal of Automation Technology, 2016
This paper describes the development of a spherical motor, hereinafter called “14-12 spherical motor.” This spherical motor utilizes two polyhedrons – a truncated regular octahedron and a regular dodecahedron – for the arrangement of permanent magnets on the rotor and electro-magnets on the stator.

Learning Polyhedrons Based On It

Mathematics Education Journal, 2018
Learning resources and media play very important roles in learningactivities in the classroom. Various learning resources complemented withinteractional media will encourage the learners to be more active in theclassroom. The objective of this present research is to analyze whatlearning resources and media are used by the teacher in learningpolyhedrons.
