ON THE TOROIDAL SURFACES OF REVOLUTION WITH CONSTANT MEAN CURVATURES
Problems of Atomic Science and Technology, Ser. Thermonuclear Fusion, 2016 It is shown that the surface with a constant mean curvature encloses the extremal volume among all toroidal surfaces of given area. The exact solution for the corresponding variational problem is derived, and its parametric analysis is performed in the limits of high and small mean curvatures.

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Minimal surfaces in euclidean 3-space and their mean curvature 1 cousins in hyperbolic 3-space
Anais da Academia Brasileira de Ciências, 2003 We show that the Hopf differentials of a pair of isometric cousin surfaces, a minimal surface in euclidean 3-space and a constant mean curvature (CMC) one surface in the 3-dimensional hyperbolic space, with properly embedded annular ends, extend ...

Advanced Engineering Materials, EarlyView.The corrosion performance of AlSi7Mg and AlSi10Mg alloys produced through selective laser melting (SLM) was examined under compressive stress in a chloride environment. Electrochemical analyses, including open‐circuit potential (OCP), potentiodynamic polarization (CPP), and electrochemical impedance spectroscopy (EIS), were complemented by scanning ...

Invariant surfaces with constant mean curvature in H2 x R [PDF]
, 2008 We classify the profile curves of all surfaces with constant mean curvature in the product space H2 x R, which are invariant under the action of a 1-parameter subgroup of isometries.

The Isoperimetric Problem in Carnot-Caratéodory Spaces
Bruno Pini Mathematical Analysis Seminar, 2017 We present some recent results obtained on the isoperimetric problem in a class of Carnot-Carathéodory spaces, related to the Heisenberg group. This is the framework of Pansu’s conjecture about the shape of isoperimetric sets.
