Computer graphics animation often lacks interaction between rigid object and granular material. In this paper, we propose a method for the deformation of the ground surface that consists of granular material when it penetrated by a rigid body object in motion. Meanwhile, the motion of the rigid object is also affected due to the collision with the ground surface. Our simulation model concerns: ...

The reasons were clear: before the InSAR era crustal deformation was measured using very time-consuming, ground based methods, as leveling, triangulation, trilateration; all requiring costly networks and measurement campaigns. The same was true for the GPS technique, appeared only few years before. SAR interferometry made things simpler and cheaper, although with some limitations; probably the ...

We study static non-axial octupole deformations in proton-rich Z = N nuclei, Ge, Se, Kr, Sr, Zr and Mo, by using the Skyrme Hartree-Fock plus BCS calculation with no restrictions on the nuclear shape. The calculation predicts that the oblate ground state in Se is extremely soft for the Y33 triangular deformation, and that in Zr the low-lying local minimum state coexisting with the prolate groun...

In this paper, we present the development of a tire rubber deformation sensing system that provides the critical information for understanding and estimation of wheel/ground interactions for mobile robots and vehicles. Polyvinylidene fluoride (PVDF)based sensors are designed and fabricated to embed on the inner tread surface to measure the tire rubber tread deformation. Analytical models of the...

The Persistent Scatterer Interferometry Wide Area Product (PSI-WAP) based on ERS1 & ERS2 radar data has been used in the seismic active area of Atalanti Faulting Zone (Central Greece) to spatially and temporally study the ground deformation for the period 1992-2003. The observed LOS velocity field, with values ranging between -0.5 to -5.0 mm/yr, combined with small standard deviation velocity v...

The inversion problem concerns the identification of parameters of a volcanic source causing observable changes in ground deformation data recorded in volcanic areas. In particular, this paper deals with the inversion of ground deformation measured by using SAR (Synthetic Aperture Radar) interferometry and an inversion approach formulated in terms of an optimization problem is proposed. Based o...

In order to study non-zero spin excitations of the recently proposed αcluster condensation in the self-conjugate 4n nuclei, spatial deformation is introduced into the model wave function of the α-cluster condensate. The rotational band states of Be are investigated as a first step of a test case for the study of the deformation of the α-cluster condensate. Calculations reproduce well the bindin...
