Is an interval the right result of arithmetic operations on intervals?

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2017
For many scientists interval arithmetic (IA, I arithmetic) seems to be easy and simple. However, this is not true. Interval arithmetic is complicated. This is confirmed by the fact that, for years, new, alternative versions of this arithmetic have been ...

Fuzzy arithmetic on systolic arrays

open access: yesParallel Computing, 1993
Abstract This paper presents parallel algorithms for fuzzy arithmetic operations on systolic arrays. A large part of the arithmetic on fuzzy numbers is referred to as fuzzy convolutions, which take O(n2) time steps when implemented sequentially. In this paper, we present two parallel algorithms. The first algorithm runs on a linear array machine in O(

Validating Explainer Methods: A Functionally Grounded Approach for Numerical Forecasting

open access: yesJournal of Forecasting, Volume 45, Issue 2, Page 819-836, March 2026.
ABSTRACT Forecasting systems have a long tradition in providing outputs accompanied by explanations. While the vast majority of such explanations relies on inherently interpretable linear statistical models, research has put forth eXplainable Artificial Intelligence (XAI) methods to improve the comprehensibility of nonlinear machine learning models.

Analysis of Economic Environment Incidence in Genetic Programming‐Evolved Multiperiod Bankruptcy Prediction Models

open access: yesIntelligent Systems in Accounting, Finance and Management, Volume 33, Issue 1, March 2026.
ABSTRACT Genetic programming (GP) is used to obtain multiperiod bankruptcy prediction models, as well as to perform a prior feature selection process for these models. Given the controversy in the field of bankruptcy prediction about the need to include (or not) variables from the economic environment as input information for the prediction models, an ...

Real‐Time Detection and Prevention of DoS Attack in Unmanned Marine Vehicles Using Machine Learning

open access: yesSECURITY AND PRIVACY, Volume 9, Issue 2, March/April 2026.
ABSTRACT Unmanned marine vehicles (UMVs) are one of the most crucial components of the underwater communication and surveillance system in the marine and oceanographic environment. This research introduces a novel approach to stabilize the connection in an unstable underwater environment by inheriting features of communication velocities.

Determination of Reorder Point in Fuzzy Sense [PDF]

open access: yesMuṭāli̒āt-i Mudīriyyat-i Ṣan̒atī, 2004
One of the most important issues in inventory control is determination of the recorder point. Are usually in forms of crisp or probability. In this article the parameters are considered as fuzzy numbers because of ambiguities in the real world.

Conditional operations on fuzzy numbers

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2013
An estimate of a joint possibility distribution of two fuzzy numbers, based on fuzzy relations with a third fuzzy variable, is suggested. This leads to the operations of conditional addition and conditional multiplication, of interactive fuzzy numbers ...

Effects of habitat quality and fine‐scale spatial structure on epiphytic lichen and bryophyte communities

open access: yesJournal of Ecology, Volume 114, Issue 3, March 2026.
Host‐tree identity, particularly bark physico‐chemical traits, emerged as the dominant driver of epiphytic lichen and bryophyte community composition in this closed‐canopy temperate forest system, while microclimate plays a subordinate role. Spatial structure and proximity contributed additional effects for both groups, but for lichens, habitat ...

Comparative energy analysis of spherical fuzzy indices in decision-making problems

open access: yesInternational Journal of Mathematics for Industry
Molecular descriptors, such as topological indices (TIs), play a crucial role in network theory, spectral graph theory, and molecular chemistry. Spherical fuzzy graphs (SFGs), an extension of picture fuzzy graphs (PFGs), utilize topological indices from ...

Computing with words with the use of inverse RDM models of membership functions

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2015
Computing with words is a way to artificial, human-like thinking. The paper shows some new possibilities of solving difficult problems of computing with words which are offered by relative-distance-measure RDM models of fuzzy membership functions.
