Asian Journal of Control, EarlyView.Abstract This study presents a non‐iterative tuning technique for a linear fractional‐order (FO) controller, based on the integral of the time‐weighted absolute error (ITAE) criterion. Minimizing the ITAE is a traditional approach for tuning FO controllers. This technique reduces the over/undershoot and suppresses the steady‐state error. In contrast to

On the projections of Laplacians under Riemannian submersions
International Journal of Mathematics and Mathematical Sciences, 2001 We give a condition on Riemannian submersions from a Riemannian manifold M to a Riemannian manifold N which will ensure that it induces a differential operator on N from the Laplace-Beltrami operator on M.

Battery Energy, EarlyView.A consensus‐based adaptive hierarchical control strategy is designed for parallel ESUs in DC electrolytic hydrogen production systems to achieve rapid SoC balancing, proportional load current sharing, and stable bus voltage recovery. ABSTRACT With the expansion of off‐grid hydrogen production systems, the randomness and volatility of renewable energy ...

ChemCatChem, EarlyView.The influence of gas diffusion layer (GDL) microstructures on mass transport and methylcyclohexane saturation (MCH) in a dehydrogenation cell was investigated using pore network modeling. We reveal that GDLs with larger pore diameters (dpore) and lower tortuosity (τ) enable enhanced MCH invasion, thereby improving reactant concentration at the catalyst.

Natural wax supported by microporous biochar to create a stable phase change material
The Canadian Journal of Chemical Engineering, EarlyView.Beeswax and hardwood charcoal are combined to form a stable and biodegradable composite phase change material. Abstract Energy storage, exploiting the latent heat of phase change materials, offers an efficient method to store and release heat. Initial developments of phase change materials and their containment targeted performance over environmental ...

Communications on Pure and Applied Mathematics, EarlyView.Abstract We analyse and clarify the finite‐size scaling of the weakly‐coupled hierarchical n$n$‐component |φ|4$|\varphi |^4$ model for all integers n≥1$n \ge 1$ in all dimensions d≥4$d\ge 4$, for both free and periodic boundary conditions. For d>4$d>4$, we prove that for a volume of size Rd$R^{d}$ with periodic boundary conditions the infinite‐volume ...

Quasi‐invariance of Gaussian measures for the 3d$3d$ energy critical nonlinear Schrödinger equation
Communications on Pure and Applied Mathematics, EarlyView.Abstract We consider the 3d$3d$ energy critical nonlinear Schrödinger equation with data distributed according to the Gaussian measure with covariance operator (1−Δ)−s$(1-\Delta)^{-s}$, where Δ$\Delta$ is the Laplace operator and s$s$ is sufficiently large. We prove that the flow sends full measure sets to full measure sets. We also discuss some simple
