RECENT SEA LEVEL CHANGES IN THE BLACK SEA FROM SATELLITE GRAVITY AND ALTIMETER MESUREMENTS
Black Sea Sea Level Change Altimetry GRACE
2018/4/18
Sea level rise causes devastating effects on coastal habitats. For example, coastal erosion and saltwater intrusion are major threats for the Black Sea coasts. So, determining sea level changes in the...

Crustal Uplift in the Longmen Shan Mountains Revealed by Isostatic Gravity Anomalies along the Eastern Margin of the Tibetan Plateau
isostatic gravity anomalies crustal uplift Longmen Shan Mountains lower crustal flow foreland basin the eastern margin of the Tibetan Plateau
2018/4/10
This study examines the relationship between high positive isostatic gravity anomalies (IGA), steep topography and lower crustal extrusion at the eastern margin of the Tibetan Plateau. IGA data has re...

2017/6/19
The assessment of ptosis degree for rejuvenation procedures, the choice of following operation technique and evaluation of surgery result are based on subjective visual examination and surgeon’s exper...
ROBUST VISION-BASED POSE ESTIMATION ALGORITHM FOR AN UAV WITH KNOWN GRAVITY VECTOR
UAV machine vision external orientation estimation motion capture system
2016/11/11
Accurate estimation of camera external orientation with respect to a known object is one of the central problems in photogrammetry and computer vision. In recent years this problem is gaining an incre...

Satellite gravity mission gravity anomaly and Global Geopotential Model
2016/10/14
The Earth’s potential information is important for exploration of the Earth’s gravity field. The techniques of measuring the Earth’s gravity using the terrestrial and ship borne technique are time con...
MARINE GEOID UNDULATION ASSESSMENT OVER SOUTH CHINA SEA USING GLOBAL GEOPOTENTIAL MODELS AND AIRBORNE GRAVITY DATA
Global Geopotential Model Geoid Undulations Airborne Gravity Gravity Missions
2016/10/14
Global geopotential models (GGMs) are vital in computing global geoid undulations heights. Based on the ellipsoidal height by Global Navigation Satellite System (GNSS) observations, the accurate ortho...
A proposal for a Bohmian ontology of quantum gravity
Bohmian mechanics loop quantum gravity emergence of space-time non-local law primitive ontology Wheeler-DeWitt equation
2016/6/15
The paper shows how the Bohmian approach to quantum physics can be applied to develop a clear and coherent ontology of non-perturbative quantum gravity. We suggest retaining discrete objects as the pr...
Gravity and Gauge
gravity gauge theory topological quantum field theory Chern-Simons theory
2016/6/15
Philosophers of physics and physicists have long been intrigued by the analogies and disanalogies between gravitational theories and (Yang-Mills-type) gauge theories. Indeed, repeated attempts to coll...
An Adynamical,Graphical Approach to Quantum Gravity and Unification
quantum gravity unification lattice gauge theory Regge calculus path integral graphs
2016/6/15
We propose an adynamical, background independent approach to quantum gravity and unification whereby the fundamental elements of Nature are graphical units of space, time and sources (in parlance of q...
Benefits of Objective Collapse Models for Cosmology and Quantum Gravity
Objective collapse Dynamical reduction Quantum gravity Cosmology
2016/6/15
We display a number of advantages of objective collapse theories for the resolution of long-standing problems in cosmology and quantum gravity. In particular, we examine applications of objective redu...
Disappearance and emergence of space and time in quantum gravity
quantum gravity foundations of spacetime theories emergent spacetime condensed matter cosmology
2016/6/15
We discuss the hints for the disappearance of continuum space and time at microscopic scale. These include arguments for a discrete nature of them or for a fundamental non-locality, in a quantum theor...
Why Einstein did not believe that General Relativity geometrizes gravity
General Relativity Einstein Geometrization Unification Inertia Gravity Geodesic Equation Meyerson
2016/6/14
I argue that, contrary to folklore, Einstein never really cared for geometrizing the gravitational or (subsequently) the electromagnetic field; indeed, he thought that the very statement that General ...
The emergence of spacetime in quantum theories of gravity
spacetime quantum gravity emergence
2016/6/13
This is the introduction to the special issue of Studies in the History and Philosophy of Modern Physics on the emergence of spacetime in quantum theories of spacetime.
Does gravity induce wavefunction collapse?An examination of Penrose's conjecture
gravity wavefunction collapse quantum mechanics general relativity measurement problem
2016/6/13
According to Penrose, the fundamental conflict between the superposition principle of quantum mechanics and the principle of general covariance of general relativity entails the existence of wavefunct...
