Bearing Fault Diagnosis Based on Natural Adaptive Moment Estimation Algorithm and Improved Octave Convolution

open access: yesIEEE Access, 2020
Fault diagnosis of rolling bearing has been the focus of research. Bearing signals are often accompanied by similar information, resulting in redundancy between data.

Exponential arcs in manifolds of quantum states

open access: yesFrontiers in Physics, 2023
The manifold under consideration consists of the faithful normal states on a sigma-finite von Neumann algebra in standard form. Tangent planes and approximate tangent planes are discussed. A relative entropy/divergence function is assumed to be given. It

A Tunable Loss Function for Robust Classification: Calibration, Landscape, and Generalization [PDF]

open access: yesIEEE Transactions on Information Theory, 2019
We introduce a tunable loss function called $\alpha $ -loss, parameterized by $\alpha \in (0,\infty]$ , which interpolates between the exponential loss ( $\alpha = 1/2$ ), the log-loss ( $\alpha = 1$ ), and the 0–1 loss ( $\alpha = \infty $ ), for the ...

Conditions for the existence of a generalization of Rényi divergence [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2020
We give necessary and sufficient conditions for the existence of a generalization of Renyi divergence, which is defined in terms of a deformed exponential function.

Dynamic Facility Location via Exponential Clocks [PDF]

open access: yes, 2014
The \emph{dynamic facility location problem} is a generalization of the classic facility location problem proposed by Eisenstat, Mathieu, and Schabanel to model the dynamics of evolving social/infrastructure networks.

Generalized Probability Functions

open access: yesAdvances in Mathematical Physics, 2009
From the integration of nonsymmetrical hyperboles, a one-parameter generalization of the logarithmic function is obtained. Inverting this function, one obtains the generalized exponential function.

Generalization and Expansion of the Hermia Model for a Better Understanding of Membrane Fouling

open access: yesMembranes, 2023
One of the most broadly used models for membrane fouling is the Hermia model (HM), which separates this phenomenon into four blocking mechanisms, each with an associated parameter n.

Fractional diffusion modeling of ion channel gating [PDF]

open access: yes, 2004
An anomalous diffusion model for ion channel gating is put forward. This scheme is able to describe non-exponential, power-law like distributions of residence time intervals in several types of ion channels.

Recursion Relations for Chromatic Coefficients for Graphs and Hypergraphs

open access: yesDiscussiones Mathematicae Graph Theory, 2022
We establish a set of recursion relations for the coefficients in the chromatic polynomial of a graph or a hypergraph. As an application we provide a generalization of Whitney’s broken cycle theorem for hypergraphs, as well as deriving an explicit ...

A new generalization of Weibull-exponential distribution with application

open access: yesJournal of Nonlinear Science and its Applications, 2018
In this article, we will introduce a new five-parameter continuous model, called the Kumaraswamy Weibull exponential distribution based on Kumaraswamy Weibull-G family [A. S. Hassan, M. Elgarhy, Adv. Appl. Stat., 48 (2016), 205–239].
