Three-stage interpolation to scattered data

open access: yesRocky Mountain Journal of Mathematics, 1984
Ein zunächst allgemein beschriebenes Vorgehen wird im zweidimensionalen Fall wie folgt konkretisiert: Zu den vorgegebenen, unregelmäßig verteilten Punkten des \({\mathbb{R}}^ 2\) wird ein geeignetes nicht- äquidistantes Rechteckgitter erzeugt; aus den in den Ausgangspunkten gegebenen Werten werden mittels lokalem \(\ell_ 2\)-Ausgleich mit quadratischen

Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

open access: yesAdvanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Fast and flexible interpolation via PUM with applications in population dynamics

open access: yes, 2015
In this paper the Partition of Unity Method (PUM) is efficiently performed using Radial Basis Functions (RBFs) as local approximants. In particular, we present a new space-partitioning data structure extremely useful in applications because of its ...

Supraparticles Composed of Graphitic Carbon Nitride Nanoparticles and Silica‐Supported Horseradish Peroxidase as Customizable Hybrid Catalysts for Photo‐Biocatalytic Cascade Reactions in Continuous Flow

open access: yesAdvanced Functional Materials, EarlyView.
Herein presented supraparticles combine the nanoparticulate photocatalyst graphitic carbon nitride with the enzyme horseradish peroxidase, which is immobilized on silica nanoparticles. In an optimized compatibility range, both catalysts operate effectively within the hybrid supraparticles and catalyze a cascade reaction consisting of the photocatalytic

Two new classes of compactly supported radial basis functions for approximation of discrete and continuous data

open access: yesEngineering Reports, 2019
Radial basis functions (RBFs), first proposed for interpolation of scattered data, have gotten the scientific community interest in the past two decades, with applications ranging from interpolation with the dual reciprocity approach of the boundary ...

Adaptive scattered data fitting by extension of local approximations to hierarchical splines

open access: yes, 2017
We introduce an adaptive scattered data fitting scheme as extension of local least squares approximations to hierarchical spline spaces. To efficiently deal with non-trivial data configurations, the local solutions are described in terms of (variable ...
