The utilization of coffee waste into fired clay brick [PDF]

open access: yes, 2015
The rapid growth of coffee industry is accompanied by a staggering increase in the amount of agriculture waste produced. In coffee producing countries, coffee wastes constitute a source of severe contamination and a serious environmental problem. In this

New variants of fuzzy optimal control problems

open access: yesAsian Journal of Control, EarlyView.
Abstract This study introduces a groundbreaking approach to optimal control problems by incorporating fuzzy conformable derivatives. Our primary goal is to identify the optimal control strategy that maximizes fuzzy performance indices while adhering to fuzzy conformable dynamical systems.

On Euler–Maclaurin formula

open access: yesJournal of Computational and Applied Mathematics, 2016
We use a simple approach to show that an Euler-Maclaurin like formula can be associated to any interpolatory quadrature rule. This result is obtained by successively adding correcting terms that are exact for polynomials of increasing degree. A decomposition of the coefficients of the Euler-Maclaurin formula in terms of the integral to compute and ...

No‐regret and low‐regret control for a weakly coupled abstract hyperbolic system

open access: yesAsian Journal of Control, EarlyView.
Abstract This paper explores an optimal control problem of weakly coupled abstract hyperbolic systems with missing initial data. Hyperbolic systems, known for their wave‐like phenomena and complexity, become even more challenging with weak coupling between subsystems.

An explicit predictor-corrector solver with applications to Burgers' equation [PDF]

open access: yes
Forward Euler's explicit, finite-difference formula of extrapolation, is used as a predictor and a convex formula as a corrector to integrate differential equations numerically.

Aspects of Unstructured Grids and Finite-Volume Solvers for the Euler and Navier-Stokes Equations [PDF]

open access: yes, 1992
One of the major achievements in engineering science has been the development of computer algorithms for solving nonlinear differential equations such as the Navier-Stokes equations.

Blend Electrodes in Lithium‐Ion Batteries: Investigation of Inhomogeneities Using a Spatially Resolved Transmission Line Model

open access: yesBatteries &Supercaps, EarlyView.
A model for blend electrodes is developed, parameterized, and validated using experimental data from a SiOx/Gr electrode. The model provides information about local states, such as the degree of lithiation or material‐specific C‐rates, distinguishing between the two active materials.

The Euler-Maclaurin formula revisited

open access: yesANZIAM Journal, 1998
The author bases this paper on the conventional Euler-Maclaurin formula. The thrust of this paper is the evaluation of Cauchy principal value (CPV) integrals and for certain Hadamard finite part integrals (FPI). To this end he includes the extra term, introduced originally by the reviewer, for the CPV and differentiates the expansion, with respect to ...

A digital shadow of CAR T cell expansion in a perfusion bioreactor: Informing optimal harvest times for autologous cell therapy

open access: yesBiotechnology Progress, EarlyView.
Using online metabolite data from the first few days of a bioreactor run, the digital shadow can forecast the cell concentration in real‐time with an accuracy of 13% (standard deviation ≈ 6%). These predictions can guide the optimal harvest time of CAR T cells for subsequent re‐infusion into the patient.
