Quantum (q, h)-Bézier surfaces based on bivariate (q, h)-blossoming
We introduce the (q, h)-blossom of bivariate polynomials, and we define the bivariate (q, h)-Bernstein polynomials and (q, h)-Bézier surfaces on rectangular domains using the tensor product.

Mutual influence of cross hatch angle and superficial roughness of honed surfaces on friction in ring-pack tribo-system [PDF]
The cylinder bore surface texture, widely produced by the honing technique, is an essential factor for a good engine performance (friction, oil consumption, running-in, wear etc.).

A Class of Weingarten Surfaces in Euclidean 3-Space
The class of biconservative surfaces in Euclidean 3-space 𝔼3 are defined in (Caddeo et al., 2012) by the equation A(grad H)=-H grad H for the mean curvature function H and the Weingarten operator A.

Steady streaming confined between three-dimensional wavy surfaces [PDF]
We present a theoretical and numerical study of three-dimensional pulsatile confined flow between two rigid horizontal surfaces separated by an average gap h, and having three-dimensional wavy shapes with arbitrary amplitude σ h where σ ∼ O(1), but long ...

New examples of surfaces in H³ with conformal normal Gauss map
In this paper we give some examples of surfaces in H³ with conformal normal Gauss map with respect to the second conformal structure and prove some global properties.Neste trabalho, damos alguns exemplos de superfícies no espaço hiperbólico de dimensão ...

Ruthenium exhibits comparable or even better alkaline hydrogen evolution reaction activity than platinum, however, the mechanistic aspects are yet to be settled, which are elucidated by combining in situ Raman spectroscopy and theoretical calculations ...

The Five Ws (and one H) of Super-Hydrophobic Surfaces in Medicine
Super-hydrophobic surfaces (SHSs) are bio-inspired, artificial microfabricated interfaces, in which a pattern of cylindrical micropillars is modified to incorporate details at the nanoscale.

The evolution of H-surfaces with a Plateau boundary condition
In this paper we consider the heat flow associated to the classical Plateau problem for surfaces of prescribed mean curvature. To be precise, for a given Jordan curve \Gamma \subset \mathbb{R}^{3} , a given prescribed mean curvature function H:\mathbb{R}^{3 ...

Calabi–Yau threefolds and moduli of abelian surfaces I [PDF]
We describe birational models and decide the rationality/unirationality of moduli spaces $\cal A$d (and $\cal A$levd) of (1, d)-polarized Abelian surfaces (with canonical level structure, respectively) for small values of d.

Nanopatterning by Molecular Self-assembly on Surfaces
The ability to pattern surfaces down to the nanoscale is of increasing importance in nanoscience research. The use of supramolecular chemistry to drive the formation of self-assembled networks allows for a bottom-up approach to achieve ...
