Research on Scattering Feature Extraction of Underwater Moving Cluster Targets Based on the Highlight Model [PDF]

open access: yesArchives of Acoustics, 2023
In detecting cluster targets in ports or near-shore waters, the echo amplitude is seriously disturbed by interface reverberation, which leads to the distortion of the traditional target intensity characteristics, and the appearance of multiple targets in

Analysing and correcting the differences between multi-source and multi-scale spatial remote sensing observations. [PDF]

open access: yesPLoS ONE, 2014
Differences exist among analysis results of agriculture monitoring and crop production based on remote sensing observations, which are obtained at different spatial scales from multiple remote sensors in same time period, and processed by same algorithms,

Dynamical properties of the growing continuum using multiple-scale method [PDF]

open access: yesApplied and Computational Mechanics, 2008
The theory of growth and remodeling is applied to the 1D continuum. This can be mentioned e.g. as a model of the muscle fibre or piezo-electric stack. Hyperelastic material described by free energy potential suggested by Fung is used whereas the change ...

Nonlinear Vibration Analysis of a Beam with a Breathing Crack

open access: yesApplied Sciences, 2019
The phenomena of sub- and super-harmonic responses make up one of the prominent nonlinear characteristics of a beam with a breathing crack. In order to fully understand the behaviors of sub- and super-harmonic resonances, it is necessary to analyze the ...

A note on the method of multiple scales [PDF]

open access: yesQuarterly of Applied Mathematics, 1980
A modification of the method of multiple scales makes use of the expansion of parameters of the system in order to remove undesirable characteristics of the solution obtained by the usual multiple-scale method. When applied to the damped harmonic oscillator, the modification leads to the exact solution.

Experience of Identity Change in People Who Reported a Diagnosis of Multiple Sclerosis : A Qualitative Inquiry [PDF]

open access: yes, 2019
Background: A diagnosis of multiple sclerosis (MS) can lead to changes to a person’s sense of self. The aim of this study was to investigate the subjective experience of identity change and subsequent adjustment to MS.

Locally periodic unfolding method and two-scale convergence on surfaces of locally periodic microstructures [PDF]

open access: yes, 2015
In this paper we generalize the periodic unfolding method and the notion of two-scale convergence on surfaces of periodic microstructures to locally-periodic situations.
