Gráficos de curvatura média constante com bordo prescrito satisfazendo a condição de declividade limitada
(Universidade Federal de Santa MariaBRMatemáticaUFSMPrograma de Pós-Graduação em Matemática, 2011-04-08)
We study problems of existence and uniqueness of constant mean curvature surfaces with prescribed boundary satisfying the bounded slope condition. The surfaces
are given as Euclidean graphs in R3 and as parabolic graphs ...
Determination of convex functions via subgradients of minimal norm
(Springer, 2020)
We show, in Hilbert space setting, that any two convex proper lower semicontinuous functions bounded from below, for which the norm of their minimal subgradients coincide, they coincide up to a constant. Moreover, under ...
Anatomy and evolution of a slope channel-complex set (Neoproterozoic Isaac Formation, Windermere Supergroup, southern Canadian cordillera): Implications for reservoir characterization
(Society for Sedimentary Geology, 2007-01)
A detailed architectural analysis was conducted in Isaac Unit 5 of the Isaac Formation in the Castle Creek area (east-central B. C., Canada). Isaac Unit 5 developed within a turbidite-dominated slope system on the ...
Tectono-sedimentary history of marine forearc basins linked to the evolution of the south central chilean margin (33?30Æ-37?S); insights from seismic data and analogue simulations.
(2010)
The origin and tectono-sedimentary development of marine forearc basins on both, slope and shelf, is strongly linked to the evolution of material transfer at a convergent margin and consequently with the morphology of ...
Fibraciones sobre superficies regladas
(Universidad Michoacana de San Nicolás de Hidalgo, 2018-03)
The goal of this thesis is the analysis of fibrations of base P1. In particular, we study the following problems: 1. To give a lower bound to the slope in the case that the surface is rational. 2. Given a fibration with ...
Deflexiones (Contraflechas) producidas por los cables de tensionamiento en las vigas simples de concreto
(2017-09-14)
In general, the most common formulas of the deflections produced by the cables in pre-stressed beams are stated, but not deduced, from the application of the principles of structural analysis. Therefore, we consider it is ...
Dissipative three-wave structures in stimulated backscattering. I. A subluminous solitary attractor
(1997-01-01)
We present a solitary solution of the three-wave nonlinear partial differential equation (PDE) model - governing resonant space-time stimulated Brillouin or Raman backscattering - in the presence of a cw pump and dissipative ...
The string swampland constraints require multi-field inflation
(Institute of Physics Publishing, 2019)
An important unsolved problem that affects practically all attempts to connect string theory to cosmology and phenomenology is how to distinguish effective field theories belonging to the string landscape from those that ...
Effect of tillage on fractal indices describing soil surface microrelief of a Brazilian Alfisol
(Geoderma, 2006)
Soil surface roughness is known to influence water infiltration, runoff and erosion. Soil surface roughness changes with management and weather and its mathematical description still remains an important issue. The main ...
