A computational model of the referential semantics of projective prepositions [PDF]

open access: yes, 2006
In this paper we present a framework for interpreting locative expressions containing the prepositions in front of and behind. These prepositions have different semantics in the viewer-centred and intrinsic frames of reference (Vandeloise, 1991).

Nutation and Reference Frame [PDF]

open access: yesHighlights of Astronomy, 1995
The reference frames are of fundamental importance in all kinds of the precession and nutation studies involving the theory, the coordinate transformation and the observations. The aim of this paper is to review all the frames used in such studies and to lead to a better consistency between them in order that theory and reductions of observations be ...

Frame of Reference Interaction. [PDF]

open access: yes, 2002
We present a unified set of 3D interaction techniques that demonstrates an alternative way of thinking about the navigation of large virtual spaces in non-immersive environments.

A two-point boundary value problem on a Lorentz manifold arising in A. Poltorak's concept of reference frame [PDF]

open access: yes, 2006
In A. Poltorak's concept, the reference frame in General Relativity is a certain manifold equipped with a connection. The question under consideration here is whether it is possible to join two events in the space-time by a time-like geodesic if they are

Reference frames and reference networks

open access: yesGeodesy and Cartography, 2015
Abstract The summary of research activities concerning reference frames and reference networks performed in Poland in a period of 2011-2014 is presented. It contains the results of research on implementation of IUGG2011 and IAU2012 resolutions on reference systems, implementation of the ETRS89 in Poland, operational work of permanent IGS/ EUREF ...

Should there be a spin-rotation coupling for a Dirac particle? [PDF]

open access: yes, 2013
It was argued by Mashhoon that a spin-rotation coupling term should add to the Hamiltonian operator in a rotating frame, as compared with the one in an inertial frame.

Perspectivism and Special Relativity

open access: yesTeorie vědy, 2021
The special theory of relativity holds significant interest for scientific perspectivists. In this paper, I distinguish between two related meanings of “perspectival,” and argue that reference frames are perspectives, provided that perspectival means ...

The Dynamical Reference Frame [PDF]

open access: yesSymposium - International Astronomical Union, 1995
Planetary and lunar ephemerides continue to improve in accuracy as they continue to be adjusted to newer and more accurate observational data. An additional improvement will be that of the orientation of the ephemerides; in the future, the ephemerides produced at JPL will be based upon the reference frame of the radio source catalogues.

Balinese Frame of Reference

open access: yesJurnal Kajian Bali (Journal of Bali Studies), 2016
: Balinese Frame of Reference. Wassmann and Dasen (1998) did a study on the acquisition of Balinese frames of reference. They pointed out that, in addition to the dominant use of absolute system, the use of relative system was also observed. This article

The potential of models and modeling for social-ecological systems research: the reference frame ModSES

open access: yesEcology and Society, 2019
Dynamic models have long been a common tool to support management of ecological and economic systems and played a prominent role in the early days of resilience research.
