This paper presents the 3D reconstruction of planar objects using the normal vector of plane and vanishing points from a single panoramic image. We get the geometric information of plane or line with feature points which use the constraints of coplanarity, perpendicularity and parallelism of planes or lines. We describe the 3D reconstruction about any features using the properties of vanishing ...

Predictive relationships are offered for the response of on-ground 2D rigid blocks undergoing rocking. Among others, this is pertinent to (1) modern or classical antiquity structures that utilize rocking as a seismic protection mechanism and (2) freestanding contents (e.g., cabinets, bookcases, museum artifacts) located on ground lower floors stiff buildings. Blocks varying dimensions were subj...

Localized dynamic pressure pulses in the magnetosheath, or jets, have been a popular topic for discussion recent decades. Studies show that they can propagate through magnetosheath and impact magnetopause, possibly showing up as geoeffective elements at ground level. However, questions still remain on how be. Previous studies limited to case during few days with only handful of events. In this ...

We are interested in Ground Penetrating Radar (GPR) as a geophysical tool useful for determining the depth of the ground water table (GWT) and for monitoring shallow water infiltration in sandy soils. At hydrostatic equilibrium, the water content distribution in a homogeneous unsaturated soil down to the water saturated zone depends on the soil water retention function. A classical way to fit r...
