Approximations for the Caputo Derivative (I)

, 2016
In this paper we construct approximations for the Caputo derivative of order $1- ,2- ,2$ and $3- $. The approximations have weights $0.5\left((k+1)^{- }-(k-1)^{- }\right)/ (1- )$ and $k^{-1- }/ (- )$, and the higher accuracy is achieved by modifying the initial and last weights using the expansion formulas for the left and right endpoints ...

Equivalences of Nonlinear Higher Order Fractional Differential Equations With Integral Equations

Mathematical Methods in the Applied Sciences, Volume 48, Issue 6, Page 6930-6942, April 2025.
ABSTRACT Equivalences of initial value problems (IVPs) of both nonlinear higher order (Riemann–Liouville type) fractional differential equations (FDEs) and Caputo FDEs with the corresponding integral equations are studied in this paper. It is proved that the nonlinearities in the FDEs can be L1$$ {L}^1 $$‐Carathéodory with suitable conditions.

A Numerical Method Combining Cubic Interpolated Propagation and Shifted Grünwald–Letnikov for Fractional Advection–Dispersion Equations

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Recent advances in the numerical solution of fractional partial differential equations have yielded promising results. In particular, the Shifted Grünwald–Letnikov (SGL) approach allows for a generalization of the traditional finite difference method to the context of fractional differential equations.

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Embedding Sustainability Commitments in the Strategic Plans of European Higher Education Institutions

Sustainable Development, EarlyView.
ABSTRACT This study analyses how European universities embed the Sustainable Development Goals (SDGs) into their strategic planning, proposing an integrative and multistakeholder measurement tool—Strategizer Scoring System (SDG‐3S). The research combines the Delphi method, content analysis of 198 strategic plans from universities in 33 European ...

US Consumer Appetite for Climate Claims on Beef Products: Does Country‐of‐Origin Matter?

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Beef cattle producers have been receiving pressure to reduce methane emissions from production. Beef products with varying climate claims have recently been introduced to the retail sector, stemming from various countries‐of‐origin. Using data from a US consumer survey, we find a subset of US consumers is willing to pay a premium for Lower ...

How Changing Food Preferences and Technology Are Transforming Food Markets

Journal of Agricultural Economics, EarlyView.
ABSTRACT The foods that consumers purchase and how they purchase food are changing over time. In this article, we discuss how health prioritization and environmental concerns, combined with new technologies, are changing consumers' food preferences and retail choices.
