In this paper we investigate the relationship between the status and the displacement of a connected weighted graph. We also obtain a product result for the displacements.

This paper is concerned with the segmentation of scene objects on the basis of their unique uniform motions. A number of previous approaches have been founded upon greyscale spatio-temporal gradient based estimation of the optic flow; these have shown some success. However optical flow only permits a limited range of recoverable motion displacements and exhibits a relatively low robustness to n...

In this study, the spatio-temporal evolution of Yellowstone deformation between 1992 and 2009 is monitored using interferometric synthetic aperture radar (InSAR) data acquired by the European Remote-Sensing Satellites (ERS-1 and ERS-2) and the Environmental Satellite (ENVISAT). These data are combined with continuous global positioning system (GPS) measurements to identify four discrete episode...

So far we have seen that magnetic resonance can • Locate the positions of spins (mainly water) with the aid of one or multiple field gradient: MRI • Characterize other metabolites by virtue of their different chemical shifts: MRS Magnetic resonance can also be exploited for • THE NON-INVASIVE MONITORING OF DISPLACEMENTS.

Creating descriptors for trajectories has many applications in robotics/human motion analysis and video copy detection. Here, we propose a novel descriptor for 2D trajectories: Histogram of Oriented Displacements (HOD). Each displacement in the trajectory votes with its length in a histogram of orientation angles. 3D trajectories are described by the HOD of their three projections. We use HOD t...

Phonons are displacements of atoms around their rest positions in a crystalline solid. They carry sound and heat, but are not classically associated with magnetism. Here, we show that phonons are, in fact, sensitive to magnetic fields, even in diamagnetic materials. We do so by demonstrating experimentally that acoustic phonons in a diamagnetic semiconductor (InSb) scatter more strongly from on...

Applying strong electric field on piezoelectric actuators, on one hand very significant electroelastic material nonlinear effects will occur, on the other hand piezo plates and shells may undergo large displacements and rotations. In order to give a precise prediction of piezolaminated smart structures under large electric field, this paper develops a finite element (FE) model accounting for bo...

We present a quantitative methodology to measure head interfraction movements within intracranial masks of commercial immobilization devices used for proton radiotherapy. A three-points tracking (3PtTrack) method was developed to measure the mask location for each treatment field over an average of 10 fractions for seven patients. Five patients were treated in supine with the Qfix Base-of-Skull...

A theoretical study of the reflection of focused acoustic beams from a fluid-solid interface is presented. The incident field is defined by a Gaussian velocity distribution along a plane emitter. The reflected field is described through its pressure field in a region not restricted to the interface. Nonspecular phenomena were exhibited at any angle of incidence by means of short wave asymptotic...
