Spherical cap harmonic analysis (SCHA) for characterising the morphology of rough surface patches
Katrin Beyer, Mahmoud S. M. Shaqfa
We use spherical cap harmonic (SCH) basis functions to analyse and reconstruct the morphology of scanned genus-0 rough surface patches with open edges. We first develop a novel one-to-one conformal mapping algorithm with minimal area distortion for paramet ...
2021A lower bound on opaque sets
It is proved that the total length of any set of countably many rectifiable curves whose union meets all straight lines that intersect the unit square U is at least 2.00002. This is the first improvement on the lower bound of 2 known since 1964. A similar ...
ELSEVIER SCIENCE BV2019Transient Impedance of Interconnected Wind Turbine Grounding Systems
Marcos Rubinstein, Antonio Sunjerga
In this paper, we analyze the grounding resistance of a vertical grounding rod located in an elevated terrain. Tall structures such as wind turbines and mobile phone base stations are often installed in remote and hilly locations to gain more power or to f ...
2019New Moduli For Banach Spaces
Modifying the moduli of supporting convexity and supporting smoothness, we introduce new moduli for Banach spaces which occur, for example, as lengths of catheti of right-angled triangles (defined via so-called quasiorthogonality). These triangles have two ...
