Marks: A New Interval Tool for Uncertainty, Vagueness and Indiscernibility

open access: yesMathematics, 2021
The system of marks created by Dr. Ernest Gardenyes and Dr. Lambert Jorba was first published as a doctoral thesis in 2003 and then as a chapter in the book Modal Interval Analysis in 2014.

An Overview of Neural Network Methods for Predicting Uncertainty in Atmospheric Remote Sensing

open access: yesRemote Sensing, 2021
In this paper, we present neural network methods for predicting uncertainty in atmospheric remote sensing. These include methods for solving the direct and the inverse problem in a Bayesian framework. In the first case, a method based on a neural network

Chebyshev model arithmetic for factorable functions [PDF]

open access: yes, 2016
This article presents an arithmetic for the computation of Chebyshev models for factorable functions and an analysis of their convergence properties. Similar to Taylor models, Chebyshev models consist of a pair of a multivariate polynomial approximating ...

Arpra: An Arbitrary Precision Range Analysis Library

open access: yesFrontiers in Neuroinformatics, 2021
Motivated by the challenge of investigating the reproducibility of spiking neural network simulations, we have developed the Arpra library: an open source C library for arbitrary precision range analysis based on the mixed Interval Arithmetic (IA)/Affine

Interval Term Rewriting System: Toward A Formal Model for Interval Computation

open access: yesTrends in Computational and Applied Mathematics, 2006
We present a term rewriting system for interval arithmetic (addition, subtraction and multiplication), toward a mathematical model for interval compu- tation.

On the Normalization of Interval Data

open access: yesMathematics, 2020
The impreciseness of numeric input data can be expressed by intervals. On the other hand, the normalization of numeric data is a usual process in many applications. How do we match the normalization with impreciseness on numeric data?

Multidimensional solution of fuzzy linear programming [PDF]

open access: yesPeerJ Computer Science, 2023
There are several approaches to address fuzzy linear programming problems (FLPP). However, due to using standard interval arithmetic (SIA), these methods have some limitations and are not complete solutions.

Three dimensional extension of Bresenham’s algorithm with Voronoi diagram [PDF]

open access: yes, 2010
Bresenham’s algorithm for plotting a two-dimensional line segment is elegant and efficient in its deployment of mid-point comparison and integer arithmetic. It is natural to investigate its three-dimensional extensions.

Surrogate-Model-Based Interval Analysis of Spherical Conformal Array Antenna with Power Pattern Tolerance

open access: yesSensors, 2022
A method based on an interval arithmetic is proposed to analyze uncertain factors such as the curvature radii, excitation amplitude, and excitation phase of a spherical conformal array antenna.

Applications of DFT to the theory of twentieth-century harmony [PDF]

open access: yes, 2015
Music theorists have only recently, following groundbreaking work by Quinn, recognized the potential for the DFT on pcsets, initially proposed by Lewin, to serve as the foundation of a theory of harmony for the twentieth century.
