Integrable Systems and projective images of Kummer surfaces
(Scuola Normale Superiore, 2000-10)
The (-1 )-involution on the Jacobian Jr of an arbitrary Riemann surfacer of genus two leads to a singular surface, the Kummer surface Icr of Jr, which,after desingularization, defines a X-3 surface Kr . We consider ample ...
Subsurface bonding of hydrogen in transition metals: dependence on surface orientation
(1994)
The calculation of the surface-induced enhancement of the binding energy of hydrogen impurities in transition metals, previously reported for close-packed surfaces, are extended to open surfaces in the fcc and bcc structures. ...
A numerical study of the simultaneous natural convective heat transfer from the top and bottom surfaces of a thin inclined plate having a wavy surface with constant height
(2019-01-01)
The purpose of the present work is to undertake a numerical study of natural convective heat transfer from a thin, two-sided, two-dimensional inclined plate having a uniform surface temperature. The surface shape is wavy, ...
Differential geometry of intersection curves in R(4) of three implicit surfaces
(Elsevier B.V., 2009-05-01)
We present algorithms for computing the differential geometry properties of intersection Curves of three implicit surfaces in R(4), using the implicit function theorem and generalizing the method of X. Ye and T. Maekawa ...

Cox Rings of K3 surfaces of Picard number three and four
(2020)
This thesis deals with Cox rings of Mori dream K3 surfaces, that is, K3 surfaces whose Cox ring is finitely generated. Research on Cox rings of K3 surfaces begins in 2009 with the work of Artebani, Hausen, Laface and ...
Adsorption of hydrogen on the surface and sub-surface of Cu(111)
(American Institute of Physics, 2013-07-30)
The interaction of atomic hydrogen with the Cu(111) surface was studied by a combined experimental-theoretical approach, using infrared reflection absorption spectroscopy, temperature programmed desorption, and density ...
Minimal Lagrangian surfaces in the tangent bundle of a Riemannian surface
(ELSEVIER SCIENCE BV, 2011)
Given an oriented Riemannian surface (Sigma, g), its tangent bundle T Sigma enjoys a natural pseudo-Kahler structure, that is the combination of a complex structure 2, a pseudo-metric G with neutral signature and a symplectic ...
Real Schottky uniformizations and Jacobians of May surfaces
(EUROPEAN MATHEMATICAL SOC, 2004)
Given a closed Riemann surface R of genus p >= 2 together with an anticonformal involution tau : R -> R with fixed points, we consider the group K(R, tau) consisting of the conformal and anticonformal auto-morphisms of R ...
Study of polypropylene surface modification by air dielectric barrier discharge operated at two different frequencies
(2012-10-18)
In this work, air dielectric barrier discharge (DBD) operating at the line frequency (60 Hz) or at frequency of 17 kHz was used to improve the wetting properties of polypropylene (PP). The changes in the surface hydrophilicity ...
