Exploring the High Dimensional Geometry of HSI Features [PDF]

open access: yes2021 11th Workshop on Hyperspectral Imaging and Signal Processing: Evolution in Remote Sensing (WHISPERS), 2021
We explore feature space geometries induced by the 3-D Fourier scattering transform and deep neural network with extended attribute profiles on four standard hyperspectral images. We examine the distances and angles of class means, the variability of classes, and their low-dimensional structures.

Assignments in the electronic spectrum of water [PDF]

open access: yes, 1974
To explain the inelastic feature at 4.5 eV in the spectrum of water and to study its spectrum in some detail, we have carried out several calculations on the excited states of water using the equations‐of‐motion method.

Consonant-vowel interactions in Modern Standard Latvian: a representational and constraint-based account

open access: yesGlossa, 2016
In this article I provide a representational and a constraint-based analysis of four interacting palatalization processes operative in Modern Standard Latvian: velar affrication, velar palatalization, yod-palatalization and front vowel raising.

Depth and Angle Evaluation of Oblique Surface Cracks Using a Support Vector Machine Based on Seven Parameters

open access: yesApplied Sciences, 2022
To intelligently and quickly verify the depths and angles of oblique surface cracks using the laser ultrasound technique, a crack geometry information evaluation method using a support vector machine (SVM) is proposed.

Contrastive hierarchies, privative features, and Portuguese vowels [PDF]

open access: yesLinguística, 2011
Dresher’s (2009) Contrastive hierarchy theory (CHT) is intended to provide a unified account of both sides of phonological primes: contrastivity and behaviour. This article explores the point and the possibility of extending CHT, which is based on binary

Deep Mid-Infrared Silicate Absorption as a Diagnostic of Obscuring Geometry Toward Galactic Nuclei [PDF]

open access: yes, 2006
The silicate cross section peak near 10um produces emission and absorption features in the spectra of dusty galactic nuclei observed with the Spitzer Space Telescope.

Gender as a probe

open access: yesBorealis: An International Journal of Hispanic Linguistics
This article discusses one of the possible roles that gender could have in the Agree operation (Chomsky 2000, 2001). Based on the analysis of the PCC in Spanish developed in Camacho Ramírez (2024), in which, in the context of a ditransitive verb, gender

FEATURE MATCHING OF HISTORICAL IMAGES BASED ON GEOMETRY OF QUADRILATERALS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
This contribution shows an approach to match historical images from the photo library of the Saxon State and University Library Dresden (SLUB) in the context of a historical three-dimensional city model of Dresden.

Correlation analysis of lift fan lip feature geometry and aerodynamic performance

open access: yesXibei Gongye Daxue Xuebao, 2023
In hover, the lip of a lift fan plays a crucial role, contributing to nearly half of the lift for the VTOL aircraft power plant. Thus, investigating the geometric parameters that influence lip performance is of significant importance. In this study, four
