On the Design Flow of the Fractional-Order Analog Filters Between FPAA Implementation and Circuit Realization

open access: yesIEEE Access, 2023
This work explicitly states the design flows of the fractional-order analog filters used by researchers throughout the literature. Two main flows are studied: the FPAA implementation and the circuit realization.

Student model initialization using domain knowledge ontology representative subset

open access: yesJournal of Technology and Science Education, 2020
In intelligent e-learning systems that adapt a learning and teaching process to student knowledge, it is important to adapt the system as quickly as possible. However, adaptation is not possible until the student model is initialized.

Identifying Ethnomathematics in the Old Mosque of Tosora

open access: yesSoutheast Asian Mathematics Education Journal, 2021
The superficial understanding and application of cultural values in the life of a pluralistic community is the main reason to conduct this research as a way to introduce the importance of national identity to students through mathematics learning.

Unstructured spline spaces for isogeometric analysis based on spline manifolds

open access: yes, 2015
Based on spline manifolds we introduce and study a mathematical framework for analysis-suitable unstructured B-spline spaces. In this setting the parameter domain has a manifold structure, which allows for the definition of function spaces that have a ...

FREQUENCY AND POWER ANALYSIS OF EEG THETA ACTIVITY DURING DIFFERENT MATHEMATICAL AND VERBAL TASK IN MALES

open access: yesInternational Journal of Health Services Research and Policy, 2020
The brain forms EEG waves due to mental processes. The aim of this study is to investigate the effectiveness of the EEG theta wave formed in the brain during different mathematical and verbal tasks.

Asymptotic spectral theory for nonlinear time series

open access: yes, 2007
We consider asymptotic problems in spectral analysis of stationary causal processes. Limiting distributions of periodograms and smoothed periodogram spectral density estimates are obtained and applications to the spectral domain bootstrap are given ...

The Mean-Field Limit for Solid Particles in a Navier-Stokes Flow [PDF]

open access: yes, 2007
We propose a mathematical derivation of Brinkman's force for a cloud of particles immersed in an incompressible fluid. Our starting point is the Stokes or steady Navier-Stokes equations set in a bounded domain with the disjoint union of N balls of radius

Mathematical analysis of memory effects and thermal relaxation in nonlinear sound waves on unbounded domains

open access: yesJournal of Differential Equations, 2021
Motivated by the propagation of nonlinear sound waves through relaxing hereditary media, we study a nonlocal third-order Jordan-Moore-Gibson-Thompson acoustic wave equation. Under the assumption that the relaxation kernel decays exponentially, we prove local well-posedness in unbounded two- and three-dimensional domains.
