Optimal control and controllability theorems for impulsive Hilfer fractional integro-differential inclusions with numerical applications

Ain Shams Engineering Journal
In this paper, we investigate Hilfer fractional integro-differential inclusions with impulsive effects. Supported by the enhanced modeling capabilities of fractional derivatives, we establish existence and controllability results for solutions to these ...

Hybrid physics–data‐driven modeling for sea ice thermodynamics and transfer learning

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Icepack–NN, a machine‐learning‐based hybrid version of the sea‐ice column model Icepack, is developed to correct state‐dependent forecast errors arising from misspecified snow thermodynamics, using neural networks applied online within the physical model.

On the validity of memristor modeling in the neural network literature

, 2019
An analysis of the literature shows that there are two types of non-memristive models that have been widely used in the modeling of so-called "memristive" neural networks.

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 ...

Vibrational Exfoliation of 2D Materials

Small, EarlyView.
Vibrational energy folds, fractures and exfoliates atomically and molecularly thin materials. Combining experimentation and computational methods, this unique vibrational synthesis pathway is revealed. This process overcomes barriers of existing approaches by processing 1000 g/L dispersions without loss in yield.

Upper and lower solutions methods for impulsive Caputo-Hadamard fractional differential inclusions

Electronic Journal of Differential Equations, 2019
In this article we use the method of lower and upper solutions combined with the fixed point theorem by Bohnnenblust-Karlin to show the existence of solutions for initial-value problems of impulsive Caputo-Hadamard fractional differential inclusions ...

Nonlocal fractional differential inclusions with impulses at variable times

Surveys in Mathematics and its Applications, 2019
By utilizing the measure of noncompactness, multivalued fixed point theory, and fractional calculus, the authors obtain the existence of mild solutions for a fractional semilinear differential inclusions with nonlocal conditions and impulses at variable times. Moreover, the topological properties of the solution set are investigated. Some known results

Excavating Early Burawoy: Toward a Third Position in the Race‐Class Debates

The British Journal of Sociology, EarlyView.
ABSTRACT This paper intervenes in contemporary sociological debates over the relationship between race and class by excavating the early writings of Michael Burawoy. Against the prevailing polarization between twin absolutist models in which either racism or capitalism alone possesses causal force, we argue that Burawoy articulates a third position—one
