Poisson inverse problems [PDF]

open access: yes, 2006
In this paper we focus on nonparametric estimators in inverse problems for Poisson processes involving the use of wavelet decompositions. Adopting an adaptive wavelet Galerkin discretization, we find that our method combines the well-known theoretical ...

Super Fuzzy Matrix of Inverse in kth Order

open access: yesRatio Mathematica, 2023
Unexpected event modelling is a affluent area of study in fuzzy matrix (FM) modelling. Every fuzzy matrix may be shown as a multidimensional cocept, but standard matrices cannot achieve this without the proper scale.

The existence of an inverse limit of inverse system of measure spaces - a purely measurable case [PDF]

open access: yes, 2009
The existence of an inverse limit of an inverse system of (probability) measure spaces has been investigated since the very beginning of the birth of the modern probability theory.

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

The Inverse Bagging Algorithm: Anomaly Detection by Inverse Bootstrap Aggregating [PDF]

open access: yes, 2016
For data sets populated by a very well modeled process and by another process of unknown probability density function (PDF), a desired feature when manipulating the fraction of the unknown process (either for enhancing it or suppressing it) consists in ...

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 \(F\to M\).

On an inversion formula [PDF]

open access: yesGlasgow Mathematical Journal, 1980
In this paper the author considers the problem of finding a formula of inversion for the integral transform defined by the equationwhere a >0, k > 0 and r-1f(r) εL (a, ∞). This transform appeared in connection with an earlier investigation [4] in which an attempt was made to devise an integral transform that could be adapted to the solution of ...

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.
