Dual embeddings of dense near polygons.
Ars Comb., 2012 Let e: S -> Sigma be a full polarized projective embedding of a dense near polygon S, i.e., for every point p of S, the set H(p) of points at non-maximal distance from p is mapped by e into a hyperplane Pi(p) of Sigma. We show that if every line of S is incident with precisely three points or if S satisfies a certain property (P(de)) then the map p bar

Near-Optimal Adaptive Polygonalization
, 1999 Consider a triangulation of the xy plane, and a general surface z = f (xy). The points of the triangle, when lifted to the surface, form a linear spline approximation to the surface. We are interested in the error between the surface and the linear approximant.

A connecting method for offset contour of planar polygon
, 2012 Triangular mesh is a digital representation mode widely used in CAD and CAM. And the connection of the offset vertexes is an important step in the edge isometry based polygon offset operation in path planning of layer milling complicated surfaces ...

Post-fire stabilization of thaw-affected permafrost terrain in northern Alaska
Scientific ReportsIn 2007, the Anaktuvuk River fire burned more than 1000 km2 of arctic tundra in northern Alaska, ~ 50% of which occurred in an area with ice-rich syngenetic permafrost (Yedoma).

Shape control of hyper-redundant modularized manipulator using variable structure regular polygon
, 2004 Hyper-redundant manipulator has more degrees of freedom than the least necessary to perform a given task, thus it has the features of overcoming conventional industrial robot's limitation such as improving its kinematics and dynamic performances ...
