Gravity model in the Korean highway [PDF]
, 2007 We investigate the traffic flows of the Korean highway system, which contains both public and private transportation information. We find that the traffic flow T(ij) between city i and j forms a gravity model, the metaphor of physical gravity as ...

Analysis of limitations on recovery of gravity field based on satellite gravity gradient data
Geodesy and Geodynamics, 2021 Although satellite gravity gradient data plays a great role in determining short-wavelength part of static gravity field model, accuracy of the long-wavelength part of gravity field model recovered by them are poor, which leads to only a few applications

Marine gravity modelling from SARAL/AltiKA data using the Least Square Collocation for the Red Sea
Egyptian Journal of Remote Sensing and Space Sciences, 2023 Marine gravity has been modeled using satellite radar altimetry for more than two decades. However, the accuracy of the predicted gravity field is constrained by the range precision and spatial coverage of the altimetry observations.

Augmented Gravity Field Modelling by Combining EIGEN_6C4 and Topographic Potential Models
Remote Sensing, 2023 One of the key goals of geodesy is to study the fine structure of the Earth’s gravity field and construct a high-resolution gravity field model (GFM). Aiming at the current insufficient resolution problem of the EIGEN_6C4 model, the refined ultra-high ...

Gravity on a fuzzy sphere [PDF]
, 2003 We propose an action for gravity on a fuzzy sphere, based on a matrix model. We find striking similarities with an analogous model of two dimensional gravity on a noncommutative plane, i.e.

Quantum Analysis of Jackiw and Teitelboim's Model for 1+1 D Gravity and Topological Gauge Theory
, 1992 We study the BRST quantization of the 1+1 dimensional gravity model proposed by Jackiw and Teitelboim and also the topological gauge model which is equivalent to the gravity model at least classically.

A spin foam model for pure gauge theory coupled to quantum gravity [PDF]
, 2002 We propose a spin foam model for pure gauge fields coupled to Riemannian quantum gravity in four dimensions. The model is formulated for the triangulation of a four-manifold which is given merely combinatorially.
