CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT This paper proposes a boundary control method for nonlinear distributed parameter systems (DPSs) with limited boundary measurements (BMs), as typically encountered in networked cyber‐physical processes with spatially distributed dynamics such as thermal and biomedical diffusion systems.

Discretization of the stationary distribution of heat in the non-homogeneous body [PDF]
Opuscula Mathematica, 2004 We give a short survey on the theory of the mixed boundary-value problem for the stationary Fourier equation in a non-homogeneous medium defined on any Lipschitz domain \(\Omega\subset\mathbb{R}^n\) (\(n\geq 2\)).

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 ...

On Metric Choice in Dimension Reduction for Fréchet Regression
International Statistical Review, EarlyView.Summary Fréchet regression is becoming a mainstay in modern data analysis for analysing non‐traditional data types belonging to general metric spaces. This novel regression method is especially useful in the analysis of complex health data such as continuous monitoring and imaging data.

A Non‐Parametric Framework for Correlation Functions on Product Metric Spaces
International Statistical Review, EarlyView.Summary We propose a non‐parametric framework for analysing data defined over products of metric spaces, a versatile class encountered in various fields. This framework accommodates non‐stationarity and seasonality and is applicable to both local and global domains, such as the Earth's surface, as well as domains evolving over linear time or time ...

Optimal Boundary Control of Non-Isothermal Viscous Fluid Flow
Fluids, 2019 We study an optimal control problem for the mathematical model that describes steady non-isothermal creeping flows of an incompressible fluid through a locally Lipschitz bounded domain.

Hardy Spaces and the Dirichlet Problem on Lipschitz Domains
Revista Matemática Iberoamericana, 1987 Let D be a Lipschitz domain in \(R^ n\) (n\(\geq 3)\) and consider the ``Hardy space'' \(H^ p(D,d\sigma)=\{u\); \(\Delta u=0\) in D, \(u(P_ 0)=0\) and \(Nu\in L^ p(\partial D,d\sigma)\}\), where \(P_ 0\in D\) is a fixed point, \(d\sigma\) is the surface measure on \(\partial D\) and Du is the non-tangential maximal function of u.

Detecting Relevant Deviations From the White Noise Assumption for Non‐Stationary Time Series
Journal of Time Series Analysis, EarlyView.ABSTRACT We consider the problem of detecting deviations from a white noise assumption in time series. Our approach differs from the numerous methods proposed for this purpose with respect to two aspects. First, we allow for non‐stationary time series. Second, we address the problem that a white noise test is usually not performed because one believes ...

Adaptive Estimation for Weakly Dependent Functional Times Series
Journal of Time Series Analysis, EarlyView.ABSTRACT We propose adaptive mean and autocovariance function estimators for stationary functional time series under 𝕃p−m‐approximability assumptions. These estimators are designed to adapt to the regularity of the curves and to accommodate both sparse and dense data designs.

The Poisson and Stokes problems on weighted spaces in Lipschitz domains and under singular forcing
Journal of Mathematical Analysis and Applications, 2019 We show the well posedness of the Poisson and Stokes problems on weighted spaces over general Lipschitz domains. For a particular range of p, we consider those weights in the Muckenhoupt class A p that have no singularities in a neighborhood of the ...
