Surface patchesCurvature connectionTransformationContinuityCommon boundaryBased on the properties of curvature connection and theory of differential geometry, a sufficient condition of curvature connection between two adjacent surfaces is obtained, and then a new method of curvature connection of surface patches...
Angle-domain common-image gathers (ADCIGs) from elastic reverse time migration (ERTM) are valuable tools for studying subsurface reservoirs. We propose a 2D workflow for generating surface-offset gathers (SOGs), which is an alternative to ADCIGs and can provide complementary information from ERTM....
Computing curvature on a mesh import point_cloud_utils as pcu # v is a #v by 3 NumPy array of vertices # f is an #f by 3 NumPy array of face indexes into v v, f = pcu.load_mesh_vfc("my_model.ply") # Compute principal min/max curvature magnitudes (k1, k2) and directions (...
Appropriate alteration of the DM curvature, i.e. adding defocus phase terms, shifts the focal zero-intensity point along the z-axis. For 2D experiments, the DM is set to a neutral (flat-field) configuration. Fluorophore activation is accomplished within a ~400 nm diameter region in the ...
The circumference and the end surface of a ball-nose end mill form a rounded corner. The radius of that round corner equals the cutting radius (i.e., half of the cutting diameter). These mills excel at creating curvature or detail-rich 3D shapes like relief. ...
Proper use of OpenGL’s lighting model provides subtle clues to the viewer about the curvature and orientation of surfaces in your scene. When you render geometry with lighting enabled, you supply normal vectors that indicate the orientation of the surface at each vertex. Surface normals are ...

Because of their extra degrees of freedom, these elements are more sensitive to the coupling between in-plane and out-of-plane motion due to curvature. The new formulation provides more consistency between adjacent elements in a curved shell. Shell normals are available for CQUAD4, CQUADR, ...
It should be added that 2D condensates do not necessarily form only in the membrane itself. Biocondensates formed in the organelle interfaces [130] may be also considered as two-dimensional, when their surface is much larger than their thickness. The formation of pseudo-two-dimensional protein co...
Unconventional resources such as tight sands, shales and coal seam gas reservoirs are defined by low matrix permeability. Economic production of these reservoirs relies on natural fracture networks and hydraulic fracture stimulation to enhance reservoir permeability. Seismic curvature analysis is commonly use...
