SDFs from Unoriented Point Clouds using Neural Variational Heat Distances
Computer Graphics Forum, EarlyView.We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from unoriented point clouds. We first compute a small time step of heat flow (middle) and then use its gradient directions to solve for a neural SDF (right). Abstract We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from ...

Stability of an Euler–Lagrange–Rassias equation in the spaces of generalized functions
, 2008 Making use of the fundamental solution of the heat equation we reformulate and prove the stability theorem of a special case of the Euler–Lagrange–Rassias functional equation in the spaces of tempered distributions and Fourier ...

A Stochastic Fractional Calculus with Applications to Variational Principles
Fractal and Fractional, 2020 We introduce a stochastic fractional calculus. As an application, we present a stochastic fractional calculus of variations, which generalizes the fractional calculus of variations to stochastic processes.

Establishing Shape Correspondences: A Survey
Computer Graphics Forum, EarlyView.Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...

Analogy between equilibrium beach profiles and closed universes
Physical Review Research, 2019 We reformulate the variational problem describing equilibrium beach profiles in the thermodynamic approach of Jenkins and Inman [J. Geophys. Res.: Oceans 111, C02003 (2006)10.1029/2005JC002899].

Computer Graphics Forum, EarlyView.Abstract We introduce mixed super‐circles, a position‐curvature formulation of the original dynamic 2D super‐helix model. Compared to the latter, purely curvature‐based model – the so‐called chained formulation –, the mixed formulation that we propose here drastically reduces the algorithmic complexity of the solving scheme – from quadratic to quasi ...

On the existence of H1-solutions to certain image registration problems
Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Modelûvannâ, 2009 The solubility of the class of nonlinear optimization problems arising in image registration is discussed. The necessary optimility conditions (Euler-Lagrange equation) for such kind of problems is a nonlinear Neumann boundary value problem which is not

The role of foreign capital flows in health finance
Economic Inquiry, EarlyView.Abstract This study develops an open economy version of the health deficit model to examine how rising health expenditures affect international capital flows, external balances, and welfare. The government issues bonds in international capital markets, linking health policy to international financial dynamics.

On the Euler-Lagrange Equation of a functional by Pólya and Szegö
, 2016 We study the regularity properties of generalized solutions of the Euler-Lagrange equation of a functional involving capacity and perimeter, related to a conjecture of Polya and Szeg

Monetary Policy When Preferences Are Quasi‐Hyperbolic
Journal of Money, Credit and Banking, EarlyView.Abstract We study discretionary monetary policy in an economy where economic agents have quasi‐hyperbolic discounting. We demonstrate that a benevolent central bank is able to keep inflation under control for a wide range of discount factors. If the central bank, however, does not adopt the household's time preferences and tries to discourage early ...
