A Generalization of Trapezoidal Fuzzy Numbers Based on Modal Interval Theory [PDF]

open access: yes, 2017
We propose a generalization of trapezoidal fuzzy numbers based on modal interval theory, which we name 'modal interval trapezoidal fuzzy numbers'. In this generalization, we accept that the alpha cuts associated with a trapezoidal fuzzy number can be ...

A New Approach Ranking of Exponential Trapezoidal Fuzzy Numbers [PDF]

open access: yes, 2012
45-47The main aim of this paper is to propose a new approach for the ranking of generalized exponential trapezoidal fuzzy numbers. The proposed ranking approach is based on rank and mode so it is named as an RM approach.

Fast Localized Calibration for Spatial‐Spectral Excitation Without Fly‐Back Gradients

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 5, Page 2253-2265, November 2026.
ABSTRACT Purpose Standard spatial‐spectral excitation pulses apply a fly‐back gradient between sub‐pulses, limiting, for example, how thin the slices can be (> 4 mm). Without fly‐back gradients, slices can be as thin as 1.7 mm but require a phase calibration for the sub‐pulses with inverted gradients due to system imperfections.

Ranking fuzzy numbers with integral value

open access: yes, 2010
[[abstract]]Ranking fuzzy numbers is important in decision making. Since very often the alternatives are evaluated by fuzzy numbers in a vague environment, a comparison between these fuzzy numbers is indeed a comparison between alternatives.

Transportation optimization with fuzzy trapezoidal numbers based on possibility theory. [PDF]

open access: yes, 2014
In this paper, a parametric method is introduced to solve fuzzy transportation problem. Considering that parameters of transportation problem have uncertainties, this paper develops a generalized fuzzy transportation problem with fuzzy supply, demand and

ANALYTICAL FORMULATIONS FOR THE LEVEL BASED WEIGHTED AVERAGE VALUE OF DISCRETE TRAPEZOIDAL FUZZY NUMBERS

open access: yes, 2021
In fuzzy decision-making processes based on linguistic information, operations on discrete fuzzy numbers are commonly performed. Aggregation and defuzzification operations are some of these often used operations.
