Off-grid hydroacoustic signal orientation estimation based on interpolation and subspace fitting in coprime arrays. [PDF]

PLoS ONE
This letter presents a novel approach to sparse Bayesian underwater acoustic signal direction estimation. The proposed method incorporates interpolation of the coprime array and signal subspace fitting.

Numerical Prediction of Two-Phase Flow through a Tube Bundle Based on Reduced-Order Model and a Void Fraction Correlation

Entropy, 2021
Predicting the void fraction of a two-phase flow outside of tubes is essential to evaluate the thermohydraulic behaviour in steam generators. Indeed, it determines two-phase mixture properties and affects two-phase mixture velocity, which enable ...

Best approximation in Chebyshev subspaces of L(l_{1}^{n},l_{1}^{n}) [PDF]

Opuscula Mathematica, 2009
Chebyshev subspaces of \(\mathcal{L}(l_1^n,l_1^n)\) are studied. A construction of a \(k\)-dimensional Chebyshev (not interpolating) subspace is given.

Interpolating Compressed Parameter Subspaces

, 2022
Inspired by recent work on neural subspaces and mode connectivity, we revisit parameter subspace sampling for shifted and/or interpolatable input distributions (instead of a single, unshifted distribution). We enforce a compressed geometric structure upon a set of trained parameters mapped to a set of train-time distributions, denoting the resulting ...

Complemented Subspaces of Spaces Obtained by Interpolation [PDF]

Journal of the London Mathematical Society, 1991
If Z is a quotient of a subspace of a separable Banach space X, and V is any separable Banach space, then there is a Banach couple (A_0,A_1) such that A_0 and A_1 are isometric to $X\oplus V$, and any intermediate space obtained using the real or complex interpolation method contains a complemented subspace isomorphic to Z.

Symplectic quantization of self-dual master Lagrangian [PDF]

, 2002
We consider the master Lagrangian of Deser and Jackiw, interpolating between the self-dual and the Maxwell-Chern-Simons Lagrangian, and quantize it following the symplectic approach, as well as the traditional Dirac scheme. We demonstrate the equivalence

Derivative Interpolating Subspace Frameworks for Nonlinear Eigenvalue Problems

SIAM Journal on Scientific Computing, 2022
We first consider the problem of approximating a few eigenvalues of a rational matrix-valued function closest to a prescribed target. It is assumed that the proper rational part of the rational matrix-valued function is expressed in the transfer function form $H(s) = C (sI - A)^{-1} B$, where the middle factor is large, whereas the number of rows of $C$

Underdetermined Direction-of-Arrival Estimation with Coprime Array via Atomic Norm Minimization [PDF]

Radioengineering, 2020
The coprime array provides the possibility of resolving more signals than the sensors for the direction-of-arrival (DOA) estimation application. However, the non-consecution of its virtual array raises challenges for making full use of the degree of ...

Approximation numbers of composition operators on $H^p$ spaces of Dirichlet series [PDF]

, 2015
By a theorem of Bayart, $\varphi$ generates a bounded composition operator on the Hardy space $\Hp$of Dirichlet series ($1\le p1/2$ if $c_0=0$ and is either identically zero or maps the right half-plane into itself if $c_0$ is positive.
