Journal of Engineering and Applied ScienceThe productivity decline of technological wells during in situ leaching (ISL) is primarily associated with clogging of well filters and the near-filter zone, leading to a significant increase in hydraulic resistance and reduction in injectivity.

Monitoring Hydro Temporal Variability in Alberta, Canada with Multi-Temporal Sentinel-1 SAR Data
Canadian Journal of Remote Sensing, 2018 Freely available high temporal and spatial resolution synthetic aperture radar (SAR) satellite data such as Sentinel-1 have made it possible for almost near-real time monitoring of surface water extent.

Computing in Geometry and TopologyLet \(P\) be a polygon with \(k\)vertices. Let \(R\) and \(B\) be two simple, interior disjoint curves on the boundary of \(P\), with \(n\) and \(m\) vertices. We show how to compute the Fréchet distance between \(R\) and \(B\) using the geodesic \(L_1\)

On the Uniqueness of Near Polygons with Three Points on Every Line
European Journal of Combinatorics, 2002 The author presents a criterion to decide whether two near \(2d\)-gons (A) with three points per line, (B) such that every two non collinear points which are both collinear with at least one point are collinear with at least two points, and (C) containing a big geodesically closed sub-near \(2(d-1)\)-gon \({\mathcal H}\), are isomorphic (\({\mathcal H}\

Locally adjusting operation on concave vertexes of planar polygon
, 2012 Triangular mesh is one of the widely used digital representation modes in CAD and CAM. And the offset operation of planar polygon takes an important role in path planning of layer milling complicated surfaces represented by triangular mesh.
