GL2(ℂ)-orbits of binary forms

Doklady Mathematics, 2010
In the present paper we study the orbits of action of the group GL2(ℂ) on the space of binary forms. The main result of the paper is the proof of the criterion which divides the GL2(ℂ)-orbits of binary forms.

Vacuum form sheet as a guide for fabrication of orbital prosthesis

The Journal of Prosthetic Dentistry, 2014
Rehabilitation with an orbital prosthesis is done when surgical reconstruction is not possible or affordable in patients with orbital exenteration. Fabrication of orbital prosthesis requires precision in placement of the ocular portion of the prosthesis on the facial moulage.

Canonical forms and orbit identification problems in machine vision

Proceedings of the 39th IEEE Conference on Decision and Control (Cat. No.00CH37187), 2002
We introduce canonical forms for perspective dynamical systems under the action of a perspective group and illustrate their application to parameter identification with the aid of a single CCD camera. We show that the parameters in the canonical form can be identified uniquely using an extended Kalman filter.

Orbital Forming of Automotive Wheel Bearings

SAE International Journal of Advances and Current Practices in Mobility, 2019
<div class="section abstract"><div class="htmlview paragraph">Orbital forming is considered an optimal assembly process for many designs of automotive wheel bearing assemblies. More specifically, this process involves forming the spindle over the inner race of the wheel bearing to maximize surface area contact on the inner ring for ...

A Correlation between Molecular Vibrations and Bond-forming Orbitals

Nature, 1948
IN a recent letter, Heath and Linnett1 suggested for the treatment of molecular vibrations a new force field, the orbital valency force field. This is based more closely on modern ideas of directed valency than is the simple valency force field. We decided to test the orbital valency force field on methane, which is a convenient molecule to use, since ...

Orbital restriction on the functional form of the Lagrangian

International Journal of Theoretical Physics, 1970
The fact that a non-relativistic particle describes an orbit imposes a restriction on the functional form of the Lagrangian. For a classical particle subjected to an arbitrary local ‘generalized force,’ the (local) Lagrangian is shown to involve, at highest, first, second and third time-derivatives of the position respectively, in one, two and three ...

Mass-Forming Inflammatory Lesions of the Orbit

2006
Inflammatory pathology, ranging from simple foreign body granuloma, to the most complex vasculitis of a collagen tissue disease, may develop space-occupying mass lesions in the orbit and present with proptosis owing to volume increase in the bony chamber.
