Fractional Variational Framework for Systems With Higher‐Order Elements. Part I: Lagrangian Construction and Equations of Motion

open access: yesAdvanced Electronic Materials, EarlyView.
This work introduces a physics‐consistent fractional variational framework for modeling systems with higher‐order elements. The developed methodology successfully incorporates energy dissipation, nonlinear dynamics, and memory effects into a unified Lagrangian formulation.

New solutions of the generalized ellipsoidal wave equation

open access: yesLe Matematiche, 1999
Certain aspects and a contribution to the theory of new forms of solutions of an algebraic form of the generalized ellipsoidal wave equation are deduced by considering the Laplace transform of a soluble system of linear differential equations. An ensuing

A lightweight interactive platform for stepwise formative assessment in algebra from single variable equations to matrix form linear systems in inclusive classrooms

open access: yesDiscover Education
Many digital mathematics tools validate only final answers, whereas teachers often need students to produce specific intermediate forms and to receive immediate guidance on where a transformation went wrong.

Spatial-Temporal Simulation of LAI on Basis of Rainfall and Growing Degree Days

open access: yesRemote Sensing, 2017
The dimensionless Leaf Area Index (LAI) is widely used to characterize vegetation cover. With recent remote sensing developments LAI is available for large areas, although not continuous. However, in practice, continuous spatial-temporal LAI datasets are

On ideals generated by two generic quadratic forms in the exterior algebra

open access: yes, 2019
Based on the structure theory of pairs of skew-symmetric matrices, we give a conjecture for the Hilbert series of the exterior algebra modulo the ideal generated by two generic quadratic forms. We show that the conjectured series is an upper bound in the

A computational study of Ising‐based solvers for discrete landscape exploration in process optimization

open access: yesAIChE Journal, EarlyView.
ABSTRACT Conceptual process design combines discrete configuration choices with continuous operating decisions, often yielding difficult mixed‐integer nonlinear or simulation‐based optimization problems. This work presents an exploratory computational assessment of Ising‐based solvers, simulated annealing, quantum annealing, and entropy computing, as ...

Enhanced biogas production via dual‐layer model predictive control for thermophilic anaerobic digesters

open access: yesAIChE Journal, EarlyView.
Abstract Thermophilic anaerobic digestion (AD) is an attractive process due to its higher biogas yield compared to mesophilic digestion. To mitigate its higher heating demand and potential process instability, a dual‐layer control architecture comprising a decision‐making layer and an adaptive model predictive control (MPC) system is proposed.

Evaluate and Measure the Level of Environmental Awareness on Campus Salahaddin University

open access: yesZanco Journal of Humanity Sciences, 2018
Principal component analysis (PCA) is a powerful tool for analyzing data. The other main advantage of PCA is that once you have found these patterns in the data, and you compress the data by reducing the number of dimensions, without much loss of ...
