FFT Interpolation from Nonuniform Samples Lying in a Regular Grid [PDF]

open access: yes, 2014
This paper presents a method to interpolate a periodic band-limited signal from its samples lying at nonuniform positions in a regular grid, which is based on the FFT and has the same complexity order as this last algorithm. This kind of interpolation is

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.

AN INVERSE PROBLEM OF RECOVERING THE RIGHT HAND SIDE OF 1D PSEUDOPARABOLIC EQUATION

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2021
Inverse problems of finding the right-hand side of a partial differential equations arise when an external source is unknown or impossible to measurement, for example, the source is in a high-temperature environment or underground.

Topological Insulators by Topology Optimization [PDF]

open access: yes, 2019
An acoustic topological insulator (TI) is synthesized using topology optimization, a free material inverse design method. The TI appears spontaneously from the optimization process without imposing requirements on the existence of pseudo spin-1/2 states ...

Frequency Risk Assessment for Power Grid with High-penetration Renewable Integration Based on Fast Kernel Learning

open access: yesZhejiang dianli, 2022
In the aftermath of power disturbance in power grid with high-penetration renewable integration, the frequency response trajectory is more likely to present large frequency deviation and high rate of change, which leads to a significant effect on ...

Adaptive cluster expansion for the inverse Ising problem: convergence, algorithm and tests [PDF]

open access: yes, 2011
We present a procedure to solve the inverse Ising problem, that is to find the interactions between a set of binary variables from the measure of their equilibrium correlations.

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 ...

Inference of the sparse kinetic Ising model using the decimation method [PDF]

open access: yes, 2015
In this paper we study the inference of the kinetic Ising model on sparse graphs by the decimation method. The decimation method, which was first proposed in [Phys. Rev. Lett.

The poolr Package for Combining Independent and Dependent p Values

open access: yesJournal of Statistical Software, 2022
The poolr package provides an implementation of a variety of methods for pooling (i.e., combining) p values, including Fisher's method, Stouffer's method, the inverse chisquare method, the binomial test, the Bonferroni method, and Tippett's method.
