A Non-Tuned Machine Learning Technique for Abutment Scour Depth in Clear Water Condition

open access: yesWater, 2020
Abutment scour is a complex three-dimensional phenomenon, which is one of the leading causes of marine structure damage. Structural integrity is potentially attainable through the precise estimation of local scour depth.

Morse numbers of complex polynomials [PDF]

open access: yesJournal of Topology 17 (2024), no. 4, e12362, 2023
To a complex polynomial function $f$ with arbitrary singularities we associate the number of Morse points in a general linear Morsification $f_{t} := f - t\ell$. We produce computable algebraic formulas in terms of invariants of $f$ for the numbers of stratwise Morse trajectories which abut, as $t\to 0$, to some point of the space or at infinity.

Influence of Implant Connection, Abutment Design and Screw Insertion Torque on Implant-Abutment Misfit

open access: yesJournal of Clinical Medicine, 2020
Background: An accurate fit at the implant-abutment interface is an important factor to avoid biological and mechanical complications. The aim of this study was to evaluate the marginal misfit at the implant-abutment interface on external and Morse taper
