Eigenvalue based inverse model of beam for structural modification and diagnostics: theoretical formulation

open access: yesLatin American Journal of Solids and Structures
In the work, the problems of the beam structural modification through coupling the additional mass or elastic support, as well as the problem of diagnostics of the beam cracks, are discussed.

Decoupling Control of Permanent Magnet Synchronous Motor With Support Vector Regression Inverse System Method

open access: yesIEEE Access, 2020
Inverse system method is effective for controlling permanent magnet synchronous motor (PMSM). A novel support vector regression(SVR) inverse system method is proposed to realize decoupling control of PMSM in the article.

New Statistical Approaches for Modeling the COVID-19 Data Set: A Case Study in the Medical Sector

open access: yesComplexity, 2022
Statistical distributions have great applicability for modeling data in almost every applied sector. Among the available classical distributions, the inverse Weibull distribution has received considerable attention. In the practice of distribution theory,

Inversion of a physical model of a trumpet [PDF]

open access: yesProceedings of the 38th IEEE Conference on Decision and Control (Cat. No.99CH36304), 2003
We deal with the inversion of a physical model of a trumpet, i.e. how should the model be controlled in order to obtain a given sound. It is shown that this problem is ill-posed since an infinity of inputs can produce the same sound. Then, a criterion based on the slowness of the musician's gestures compared to the sound signal evolution is used: this ...

Impeded inverse energy transfer in the Charney--Hasegawa--Mima model of quasi-geostrophic flows

open access: yes, 2010
The behaviour of turbulent flows within the single-layer quasi-geostrophic (Charney-Hasegawa-Mima) model is shown to be strongly dependent on the Rossby deformation wavenumber lambda (or free-surface elasticity). Herein, we derive a bound oil the inverse

Generative Modelling With Inverse Heat Dissipation

open access: yesCoRR, 2022
While diffusion models have shown great success in image generation, their noise-inverting generative process does not explicitly consider the structure of images, such as their inherent multi-scale nature. Inspired by diffusion models and the empirical success of coarse-to-fine modelling, we propose a new diffusion-like model that generates images ...

Application of an optimal estimation inverse method to GPS/MET bending angle observations [PDF]

open access: yes, 2001
Palmer et al. [2000] describes an optimal estimation inverse method for radio occultation (RO) bending angle measurements to retrieve simultaneously temperature, humidity, and surface pressure; outlines quality control procedures for retrieved profiles ...

An Inverse Model for Raindrop Size Distribution Retrieval with Polarimetric Variables

open access: yesRemote Sensing, 2018
This paper proposes an inverse model for raindrop size distribution (DSD) retrieval with polarimetric radar variables. In this method, a forward operator is first developed based on the simulations of monodisperse raindrops using a T-matrix method, and ...

Comparative inverse analysis of satellite (MOPITT) and aircraft (TRACE-P) observations to estimate Asian sources of carbon monoxide [PDF]

open access: yes, 2004
We use an inverse model analysis to compare the top-down constraints on Asian sources of carbon monoxide (CO) in spring 2001 from (1) daily MOPITT satellite observations of CO columns over Asia and the neighboring oceans and (2) aircraft observations of ...
