Comparative Analysis of Real-Time Fall Detection Using Fuzzy Logic Web Services and Machine Learning

open access: yesTechnologies, 2020
Falls are the main cause of susceptibility to severe injuries in many humans, especially for older adults aged 65 and over. Typically, falls are being unnoticed and interpreted as a mere inevitable accident.

Fuzzy Regression Analysis with an Application [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2006
This work investigates the analysis of fuzzy regression in case of the data being fuzzy or non-fuzzy. The analysis is performed by several methods , such as fuzzy linear regression (FLR) and modified one, and fuzzy linear regression with least squares (

A hybrid energy storage strategy based on multivariable fuzzy coordinated control of photovoltaic grid‐connected power fluctuations

open access: yesIET Renewable Power Generation, 2021
Aiming at the problem that the grid‐connected power fluctuation of the photovoltaic power system affects the stability of grid operation, a multivariable fuzzy coordinated control strategy for photovoltaic grid‐connected power fluctuation based on super ...

Efficiency evaluation in fuzzy two-stage data envelopment analysis based on fuzzy arithmetic approach [PDF]

open access: yesتصمیم گیری و تحقیق در عملیات, 2022
Purpose: In classical data envelopment analysis models, a production system for measuring performance is considered as a black box and no attention is paid to the internal structure of decision-making units in the process of evaluation performance ...

Assessment of investment decisions in bulk shipping through fuzzy real options analysis [PDF]

open access: yesMaritime Economics & Logistics, 2021
The global shipping market has been depressed and turbulent since 2008. Shipping companies have had to be more cautious with their investments, so as to buck the trend and get through this difficult period. Traditional net present value methods cannot help enterprises make effective investment decisions.

Approach to solve multi-criteria group decision-making problems by exponential operational law in generalised spherical fuzzy environment

open access: yesCAAI Transactions on Intelligence Technology, 2020
The construction of generalised spherical fuzzy number (GSFN) is a reliable philosophy to design and understanding of vagueness and impreciseness. In this study, at first, the authors have defined the generalised spherical fuzzy set and discussed its ...

Oriented Fuzzy Numbers vs. Fuzzy Numbers

open access: yesMathematics, 2021
A formal model of an imprecise number can be given as, inter alia, a fuzzy number or oriented fuzzy numbers. Are they formally equivalent models? Our main goal is to seek formal differences between fuzzy numbers and oriented fuzzy numbers.

Some properties of fuzzy real numbers [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2016
In the mathematical analysis, there are some theorems and definitions that established for both real and fuzzy numbers. In this study, we try to prove  Bernoulli's inequality in fuzzy real numbers with some of its applications.

A novel type-2 hexagonal fuzzy logic approach for predictive safety stock management for a distribution business

open access: yesScientific Reports, 2023
Safety stock is an important method to overcome variability in inventory management. The classical approach to safety stock decisions relies on historical demand and lead time statistical data, which may not capture the uncertainty and complexity of the ...
