On orthogonal polynomials and related discrete integrable systems [PDF]

open access: yes, 2006
Orthogonal polynomials arise in many areas of mathematics and have been the subject of interest by many mathematicians. In recent years this interest has often arisen from outside the orthogonal polynomial community after their connection with ...

Optimal binary space partitions for orthogonal objects [PDF]

open access: yesJournal of Algorithms, 1992
Summary: A binary space partition, or BSP, is a scheme for recursively dividing a configuration of objects of hyperplanes until all objects are separated. BSPs are widely used in computer graphics as the underlying data structure for computations such as real-time hidden-surface removal, ray tracing, and solid modeling.

Embedded Mean-Field Theory with Block-Orthogonalized Partitioning [PDF]

open access: yesJournal of Chemical Theory and Computation, 2017
Embedded mean-field theory (EMFT) provides a simple, flexible framework for describing subsystems at different levels of mean-field theory. Subsystems are defined by partitioning a one-particle basis set, with a natural choice being the atomic orbital (AO) basis. Although generally well behaved, EMFT with AO partitioning can exhibit unphysical collapse

SYK Model with global symmetries in the double scaling limit

open access: yesJournal of High Energy Physics, 2023
We discuss the double scaling limit of the SYK model with global symmetries. We develop the chord diagram techniques to compute the moments of the Hamiltonian and the two point function in the presence of arbitrary chemical potential.

Improved Local Ternary Patterns for Automatic Target Recognition in Infrared Imagery

open access: yesSensors, 2015
This paper presents an improved local ternary pattern (LTP) for automatic target recognition (ATR) in infrared imagery. Firstly, a robust LTP (RLTP) scheme is proposed to overcome the limitation of the original LTP for achieving the invariance with ...

Efficient Distortion Mitigation and Partition Reduction in Mapping Global Geodata: Dual Orthogonal Equidistant Cylindrical Projection Approach

open access: yesISPRS International Journal of Geo-Information, 2023
The rapid growth in Earth’s global geospatial data necessitates an efficient system for organizing the data, facilitating data fusion from diverse sources, and promoting interoperability.

Spaces of states of the two-dimensional $O(n)$ and Potts models

open access: yesSciPost Physics, 2023
We determine the spaces of states of the two-dimensional $O(n)$ and $Q$-state Potts models with generic parameters $n,Q\in \mathbb{C}$ as representations of their known symmetry algebras.

Expansion Methods for Solving Linear Integral Equations with Multiple Time Lags Using B-Spline and Orthogonal Functions [PDF]

open access: yesEngineering and Technology Journal, 2011
The main portion of the paper is devoted for constructing approximated solutions of linear integral equations with multiple time lags (IEMTL) using two different types of basis functions B-spline functions and Orthogonal functions containing (Laguerre ...

ORTHOGONAL PARTITIONS OF THE 6times6 LATIN SQUARES [PDF]

open access: yesAnnals of Eugenics, 1946
The articles published by the Annals of Eugenics (1925–1954) have been made available online as an historical archive intended for scholarly use. The work of eugenicists was often pervaded by prejudice against racial, ethnic and disabled groups. The online publication of this material for scholarly research purposes is not an endorsement of those views
