Robust Constrained Inverse Beamforming Algorithm Based on Space Time Adaptive Processing

open access: yesIEEE Access, 2019
The power of Beidou satellite signals is very low, so it is vulnerable to interfering sources and in the presence of jamming. Therefore, a robust constrained inverse beamforming algorithm based on space-time adaptive processing is proposed, which can not

Adaptive Spectral Inversion for inverse medium problems

open access: yesInverse Problems, 2023
Abstract A nonlinear optimization method is proposed for the solution of inverse medium problems with spatially varying properties. To avoid the prohibitively large number of unknown control variables resulting from standard grid-based representations, the misfit is instead minimized in a small subspace spanned by the first few ...

Design of High Temperature Ti–Al–Cr–V Alloys for Maximum Thermodynamic Stability Using Self-Organizing Maps

open access: yesMetals, 2019
Data generated for the Ti−Al−Cr−V system of metallic alloys from our previous publication, where the composition of 102 alloys were computationally Pareto optimized with the objective of simultaneously maximizing the Young’s ...

Discovery of New Ti-Based Alloys Aimed at Avoiding/Minimizing Formation of α” and ω-Phase Using CALPHAD and Artificial Intelligence

open access: yesMetals, 2020
In this work, we studied a Ti-Nb-Zr-Sn system for exploring novel composition and temperatures that will be helpful in maximizing the stability of β phase while minimizing the formation of α” and ω-phase. The Ti-Nb-Zr-Sn system is free of toxic elements.

Robust Prediction of Single and Multiple Point Protein Mutations Stability Changes

open access: yesBiomolecules, 2019
Accurate prediction of protein stability changes resulting from amino acid substitutions is of utmost importance in medicine to better understand which mutations are deleterious, leading to diseases, and which are neutral.

On F-inverse covers of inverse monoids

open access: yesJournal of Pure and Applied Algebra, 2006
An inverse monoid \(F\) in which every class with respect to the smallest group congruence has a maximal element in the natural partial order is called an \(F\)-inverse monoid. Such a monoid \(F\) is an \(F\)-inverse cover of an inverse monoid \(M\) if there is an idempotent-separating onto homomorphism \(F\to M\).

An holomorphic study of Smarandache automorphic and cross inverse property loops [PDF]

open access: yes, 2008
By studying the holomorphic structure of automorphic inverse property uasigroups and loops[AIPQ and (AIPL)] and cross inverse property quasigroups and loops[CIPQ and (CIPL)], it is established that the holomorph of a loop is a Smarandache; AIPL, CIPL, K ...

The Division Ring Over Conjugate Product

open access: yesIEEE Access, 2019
In this paper, we investigate the rational fractions in the framework of conjugate product and establish a division ring. Some conjugate properties on the proposed division ring are obtained, and the similarity and consimilarity properties are ...

Interesting Explicit Expressions of Determinants and Inverse Matrices for Foeplitz and Loeplitz Matrices

open access: yesMathematics, 2019
Foeplitz and Loeplitz matrices are Toeplitz matrices with entries being Fibonacci and Lucas numbers, respectively. In this paper, explicit expressions of determinants and inverse matrices of Foeplitz and Loeplitz matrices are studied.
