A Lightweight Procedural Layer for Hybrid Experimental–Computational Workflows in Materials Science

Advanced Engineering Materials, EarlyView.
We unveil a prototype hybrid‐workflow framework that fuses automatedcomputation with hands‐on experiments. Built atop pyiron, a lightweight, parameterized layer translates procedure descriptions into executable manual steps, syncing instrument settings, human interventions, and data capture in real‐time today.

Nonlinear Optimal Control for Guidance and 3D Trajectory Tracking of Missiles

Guidance, Navigation and Control
The paper proposes a nonlinear optimal control method for guidance and three-dimensional trajectory tracking of missiles. It is proven that the kinematic–dynamic model of the missile is differentially flat, which confirms the controllability of this ...

Error-feedback for amplifier linearization

, 1998
A novel general linearization topology called `Error-Feedback' is presented and applied to the linearization of amplifiers. Error-Feedback uses the difference/error between (linearly) scaled input and output signal in its feedback loop to reduce non ...

Input-state feedback linearization for stable radio-frequency magnetron control

Systems Science & Control Engineering
In this study, we propose a nonlinear control method to stabilize the oscillation of magnetrons. These power microwave devices have a complex dynamics, which can be modelled as simple third-order nonlinear oscillator. This circuit can be controlled using

Morphology, Transport, and Dynamics of Protein Adsorption in Open‐Cell Metal Foam

Advanced Engineering Materials, EarlyView.
Stainless steel (SS) open‐cell foams are shown to adsorb more protein per unit area than previously reported 316L SS and chromium oxide surfaces under static and flow conditions. An integrated approach combining 3D pore imaging, flow simulation, and protein adsorption experiments characterizes the foam’s performance.
