Multimatcher Model to Enhance Ontology Matching Using Background Knowledge

Information, 2021
Ontology matching is a rapidly emerging topic crucial for semantic web effort, data integration, and interoperability. Semantic heterogeneity is one of the most challenging aspects of ontology matching.

Self-Similar Symmetry Model and Cosmic Microwave Background

Frontiers in Applied Mathematics and Statistics, 2016
In this paper, we present the self-similar symmetry (SSS) model that describes the hierarchical structure of the universe. The model is based on the concept of self-similarity, which explains the symmetry of the cosmic microwave background (CMB).

Determining the Model Spatial Position under Intense Background Illumination

Глобальная ядерная безопасность, 2022
The paper describes the method that makes it possible to set up aeroballistic tests to study the aerodynamic characteristics of high-speed objects in conditions where there is an intense self-illumination (solid light) of the object.

Background independent matrix models [PDF]

Physics Letters B, 1998
A class of background independent matrix models is made for which the structure of both local gauge symmetries and classical solutions is clarified. These matrix models do not involve a space-time metric and provide the matrix analogs of topological Chern-Simons and BF theories.

An improved ViBe algorithm based on adaptive detection of moving targets

Journal of Measurement Science and Instrumentation, 2020
There exists a Ghost region in the detection result of the traditional visual background extraction（ViBe） algorithm, and the foreground extraction is prone to false detection or missed detection due to environmental changes.

A machine vision based algorithm for extracting the contour of moving targets in surveillance videos

Dianzi Jishu Yingyong
In surveillance videos, moving targets are easily affected by edge blurring and background noise interference, resulting in inaccurate contour extraction results. Therefore, a machine vision based algorithm for extracting the contour of moving targets in

Finslerian dipolar modulation of the CMB power spectra at scales $$2

European Physical Journal C: Particles and Fields, 2017
A common explanation for the CMB power asymmetry is to introduce a dipolar modulation at the stage of inflation, where the primordial power spectrum is spatially varying.

A toy model for background independent string field theory

Journal of High Energy Physics, 2022
We study gauge theories of background fields associated to BRST quantized spinning particle models and identify background-independent algebraic structures which allow to systematically reduce the spectrum of fields and subject some of them to dynamical ...

Background model for the Majorana Demonstrator

Journal of Physics: Conference Series, 2017
The MAJORANA Collaboration is constructing a system containing 44 kg of high-purity Ge (HPGe) detectors to demonstrate the feasibility and potential of a future tonne-scale experiment capable of probing the neutrino mass scale to ~15 meV. To realize this, a major goal of the MAJORANA DEMONSTRATOR is to demonstrate a path forward to achieving a ...
