Nonlinear System Identification of an All Movable Fin with Rotational Freeplay by Subspace-Based Method

open access: yesApplied Sciences, 2020
To interpret the nonlinear system identification of multi-degree-of-freedom vibrating structures with freeplay, an estimation procedure based on subspace method in time domain is developed in this paper.

The subalgebra of graded central polynomials of an associative algebra [PDF]

open access: yes, 2014
Let $F$ be a field and let $F \langle X \rangle$ be the free unital associative $F$-algebra on the free generating set $X = \{ x_1, x_2, \dots \}$. A subalgebra (a vector subspace) $V$ in $F \langle X \rangle$ is called a $T$-subalgebra (a $T$-subspace ...

Machine Learning Techniques to Map the Impact of Urban Heat Island: Investigating the City of Jeddah

open access: yesLand, 2023
Over the last decades, most agricultural land has been converted into residential colonies to accommodate the rapid population expansion. Population growth and urbanization result in negative consequences on the environment.

Combined central and subspace clustering for computer vision applications [PDF]

open access: yesProceedings of the 23rd international conference on Machine learning - ICML '06, 2006
Central and subspace clustering methods are at the core of many segmentation problems in computer vision. However, both methods fail to give the correct segmentation in many practical scenarios, e.g., when data points are close to the intersection of two subspaces or when two cluster centers in different subspaces are spatially close. In this paper, we

An Improved Lower Bound for Sparse Reconstruction from Subsampled Walsh Matrices

open access: yesDiscrete Analysis, 2023
An Improved Lower Bound for Sparse Reconstruction from Subsampled Walsh Matrices, Discrete Analysis 2023:3, 9 pp. There are many situations, often of great practical importance, where one would like to obtain a good approximation for a mathematical ...

Coordinate-free quantization of first-class constrained systems [PDF]

open access: yes, 1996
The coordinate-free formulation of canonical quantization, achieved by a flat-space Brownian motion regularization of phase-space path integrals, is extended to a special class of closed first-class constrained systems that is broad enough to include ...

Cone-volume measure and stability [PDF]

open access: yes, 2017
We prove stability results for two central inequalities involving the cone-volume measure of a centered convex body: the subspace concentration conditions and the U-functional/volume inequality.

Large-scale electrophysiology and deep learning reveal distorted neural signal dynamics after hearing loss

open access: yeseLife, 2023
Listeners with hearing loss often struggle to understand speech in noise, even with a hearing aid. To better understand the auditory processing deficits that underlie this problem, we made large-scale brain recordings from gerbils, a common animal model ...

Contour projected dimension reduction

open access: yes, 2009
In regression analysis, we employ contour projection (CP) to develop a new dimension reduction theory. Accordingly, we introduce the notions of the central contour subspace and generalized contour subspace.

Asymptotic forecast uncertainty and the unstable subspace in the presence of additive model error [PDF]

open access: yes, 2018
It is well understood that dynamic instability is among the primary drivers of forecast uncertainty in chaotic, physical systems. Data assimilation techniques have been designed to exploit this phenomenon, reducing the effective dimension of the data ...
