Although many work have been done on corner detection, no generally accepted mathematical definition exists. This paper gives an explicit definition of corner which is based on the multi-orientation nature of corner and presents an algorithm for corner detection based on orientation estimation. Experimental results show that the proposed algorithm is more accurate and noise-robust compared with...

Number of Papers published in peer-reviewed journals: Number of Papers published in non peer-reviewed journals: A Study of Supersonic Compression-Corner Interactions using Hybrid LES/RANS Models Report Title This research has developed a new hybrid large-eddy /Reynolds-averaged Navier-Stokes turbulence closure strategy specifically designed for strongly interacting, wall-bounded flows. The mode...

Two axisymmetric shock-wave / boundary-layer interaction (SWBLI) cases are used to benchmark oneand two-equation Reynolds-averaged Navier-Stokes (RANS) turbulence models. This validation exercise was executed in the philosophy of the NASA Turbulence Modeling Resource and the AIAA Turbulence Model Benchmarking Working Group. Both SWBLI cases are from the experiments of Kussoy and Horstman for ax...

Let S be a set of n points in the unit square [0, 1], one of which is the origin. We construct n pairwise interior-disjoint axis-aligned empty rectangles such that the lower left corner of each rectangle is a point in S, and the rectangles jointly cover at least a positive constant area (about 0.09). This is a first step towards the solution of a longstanding conjecture that the rectangles in s...
