The Ornstein-Uhlenbeck semigroup in exterior domains
Abstract.Let Ω be an exterior domain in $$\mathbb{R}^n .$$ It is shown that Ornstein-Uhlenbeck operators L generate C0-semigroups on Lp(Ω) for p ∈ (1, ∞) provided ∂Ω is smooth. The method presentedExpand

Bayesian inference in estimation of distribution algorithms
TLDR
A new approach to model fitting in EDAs based on Bayesian inference, a method which utilizes prior distributions on model parameters and generates each successive population from the posterior predictive distribution. Expand

Approximate Record Matching Using Hash Grams
TLDR
We present a new probabilistic h-gram (hash gram) record matching technique for duplicate record detection applicable to a variety of data types and data sizes by transforming data into its equivalent numerical realities. Expand

Spectrum created by line defects in periodic structures
The spectrum of periodic differential operators typically exhibits a band-gap structure. In this paper, we will consider perturbations to periodic differential operators and investigate the spectrumExpand

The Proper Dissipative Extensions of a Dual Pair
Let A and $${(-\widetilde{A})}$$(-A~) be dissipative operators on a Hilbert space $${\mathcal{H}}$$H and let $${(A,\widetilde{A})}$$(A,A~) form a dual pair, i.e. $${A \subset \widetilde{A}^*}$$A⊂A~∗,Expand

Spectral results for perturbed periodic Jacobi matrices using the discrete Levinson technique
For an arbitrary Hermitian period-$T$ Jacobi operator, we assume a perturbation by a Wigner-von Neumann type potential to devise subordinate solutions to the formal spectral equation for a (possiblyExpand

Estimates for the lowest eigenvalue of a star graph
We derive new estimates for the lowest eigenvalue of the Schrodinger operator associated with a star graph in R2. We achieve this by a variational method and a procedure for identifying testExpand

OWL-DL Domain-Models as Abstract Workflows
TLDR
We propose, and demonstrate, that a domain model for a given concept, formalized in OWL, can be used as an abstract workflow model, which can be automatically converted into a context-specific, concrete, self-annotating workflow. Expand

Automated discovery of multi-faceted ontologies for accurate query answering and future semantic reasoning
TLDR
We propose a multi-faceted classification technique for performing structural analysis on knowledge domain clusters, using a novel Ontology Guided Data Linkage (OGDL) framework. Expand
