In Antarctica, Global Positioning System (GPS) vertical time series exhibit non-linear signals over a wide range of temporal scales. To explain these non-linearities, number hypotheses have been proposed, among them the short-term rapid solid Earth response to contemporaneous ice mass change. Here we use GPS reveal variations in surface balance (SMB) Southern Antarctic Peninsula (SAP). At four ...

Whereas much work has been done to describe N -dimensional orientations in terms of principal rotations, these developments have not been extended to the descriptions of N -dimensional kinematics. For threedimensional rotations the angular velocity can be related to derivatives of the principal angle and axis. Following a similar procedure this paper develops the kinematics for N -dimensional r...

In conventional differential radar interferometry (DInSAR), the ground surface displacement can be measured along the line-ofsight. In order to measure the vertical and horizontal displacements DInSAR results of the same deformation derived from at least two different look directions are required. This study utilised the DInSAR results generated from ENVISAT data acquired from three different l...

Reliable estimates of vertical, inline and crossline components of apparent displacements in time-lapse seismic images are difficult to obtain for two reasons. First, features in 3-D seismic images tend to be locally planar, and components of displacement within the planes of such features are poorly resolved. Second, searching directly for peaks in 3-D cross-correlations is less robust, more c...

INTRODUCTION The aim of this study was to evaluate the biomechanical effects of chincup treatment by using a 3-dimensional finite element model. METHODS Three-dimensional models of the mandible and the temporomandibular joint were modeled and analyzed. The final mesh consisted of 1572 solid elements with 5432 nodes. The chincup with 500 g of force was applied in a direction from the chin towa...

Synthetic aperture radar (SAR) images provide scattering information which can be used under any weather conditions for glacier monitoring. The purpose is to estimate a displacement field characterizing at each position the local speeds and orientations of the glacier movement. The recent method proposed in [1] builds a vector field from the similarities existing between two SAR images co-regis...

Synthetic aperture radar (SAR) images acquired by radar satellites at different times can be combined into interferograms that reveal information about the change in range from ground to satellite, wrapped into phase fringes corresponding to half the radar wavelength. We describe a methodology that uses Markov random field (MRF) regularization and simulated annealing optimization to unwrap such...

Analysis of surface-based displacement vectors using spherical harmonic description (SPHARM) localizes shape changes accurately. However, it does not allow differentiating volume variations from shifting and/or bending. We propose a new approach to quantify local volume changes by computing the surface-based Jacobian determinant. This measurement is computed on the displacement vector fields es...

We introduce P2P-NET, a general-purpose deep neural network which learns geometric transformations between point-based shape representations from two domains, e.g., meso-skeletons and surfaces, partial and complete scans, etc. The architecture of the P2P-NET is that of a bi-directional point displacement network, which transforms a source point set to a target point set with the same cardinalit...
