Granular F-transform and its application

open access: yesCoRR, 2022
This contribution introduces the concept of granular F-transform and investigates its basic properties by using the theory of fuzzy numbers and horizontal membership functions. Further, we present a numerical method based on granular F-transform to solve a fuzzy prey-predator model consisting of two prey and one predator due to its natural variability ...

Random Laplace Transform [PDF]

open access: yesThe Egyptian Statistical Journal, 1993
The theory of Laplace Transform (L. T. ) assumed he transformation of deterministic functions, F(t), and computed their corresponding deterministic transfer functions,  f(s). In this paper, the author introduces the random Laplace transform (R. L.

A Summary of F-Transform Techniques in Data Analysis [PDF]

open access: yesElectronics, 2021
Fuzzy transform is a technique applied to approximate a function of one or more variables applied by researchers in various image and data analysis. In this work we present a summary of a fuzzy transform method proposed in recent years in different data mining disciplines, such as the detection of relationships between features and the extraction of ...

A general quantum Laplace transform

open access: yesAdvances in Difference Equations, 2020
In this paper, we introduce a general quantum Laplace transform L β $\mathcal{L}_{\beta }$ and some of its properties associated with the general quantum difference operator D β f ( t ) = ( f ( β ( t ) ) − f ( t ) ) / ( β ( t ) − t ) ${D}_{\beta }f(t)= ({

F-Transform Inspired Weak Solution to a Boundary Value Problem

open access: yesAxioms, 2019
We propose and show efficiency of a new fuzzy-transform-based numerical method of solving ordinary differential equations with boundary conditions. The focus is on weak solutions and a special construction of a two-parameterized family of test functions.

Local versions of the Wiener–Lévy theorem

open access: yesМатематичні Студії, 2022
Let $h$ be a real-analytic function on the neighborhood of some compact set $K$ on the plane, and let $f(y)$ be the Fourier--Stieltjes transform of a complex measure of a finite total variation without singular components on the Euclidean space.

A Seneta's Conjecture and the Williamson Transform [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2023
Considering slowly varying functions (SVF), %Seneta (2019) Seneta in 2019 conjectured the following implication, for $\alpha\geq1$,$$\int_0^x y^{\alpha-1}(1-F(y))dy\textrm{\ is SVF}\ \Rightarrow\ \int_{0}^x y^{\alpha}dF(y)\textrm{\ is SVF, as $x\to\infty$

Bitcoin Analysis and Forecasting through Fuzzy Transform

open access: yesAxioms, 2020
Sentiment analysis to characterize the properties of Bitcoin prices and their forecasting is here developed thanks to the capability of the Fuzzy Transform (F-transform for short) to capture stylized facts and mutual connections between time series with ...
