On the valuations of the near polygon ℍn [PDF]
, 2018 We characterize the valuations of the near polygon that are induced by classical valuations of the dual polar space DW (2n - 1, 2) into which it is isometrically embeddable. An application to near 2n-gons that contain as a full subgeometry is given.

Machine-assisted discovery of integrable symplectic mappings
Physical Review Research, 2023 We present a new automated method for finding integrable symplectic maps of the plane. These dynamical systems possess a hidden symmetry associated with an existence of conserved quantities, i.e., integrals of motion.

Searching for the closest-pair in a query translate
Journal of Computational Geometry, 2020 We consider a range-search variant of the closest-pair problem. Let $\varGamma$ be a fixed shape in the plane. We are interested in storing a given set of $n$ points in the plane in some data structure such that for any specified translate of $\varGamma$

Near polygons with a nice chain of sub-near polygons
Journal of Combinatorial Theory, Series A, 2004 A near polygon is a partial linear space \({\mathcal S}=({\mathcal P},{\mathcal L})\) with the property that for every point \(p\in {\mathcal P}\) and for every line \(L\in {\mathcal L}\) there exists a unique point on \(L\) nearest to \(p\). Here distances \(d(\cdot,\cdot)\) are measured in the collinearity graph \(\Gamma\). If \(n=\text{diam}(\Gamma)\

Pulse Tripling Circuit and Twelve Pulse Rectifier Combination for Sinusoidal Input Current
IEEE Access, 2021 In this paper, a novel pulse tripling circuit (PTC) is suggested, to upgrade a polygon autotransformer 12-pulse rectifier (12-PR) to a 36-pulse rectifier (36-PR) with a low power rating.
