Advanced Engineering Materials, EarlyView.Creep experiments at 900°C on coarse‐grained steel‐ceramic composites containing recycled magnesia reveal that higher ceramic volume fractions significantly enhance the creep resistance. Detailed EBSD investigations identify subgrain formation in the steel matrix as the dominant deformation mechanism.

knowledge_diffusion_with_complex_cognition [PDF]
This paper aims to understand some of the mechanisms which dominate the phenomenon of knowledge diffusion in the process that is called ‘interactive learning’. We examine how knowledge spreads in a network in which agents interact by word of mouth.

Steady state evaluation of distributed secondary frequency control strategies for microgrids in the presence of clock drifts [PDF]
, 2017 Secondary frequency control, i.e., the task of restoring the network frequency to its nominal value following a disturbance, is an important control objective in microgrids.

Additive Gaussian Process Regression for Predictive Design of High‐Performance, Printable Silicones
Advanced Engineering Materials, EarlyView.A chemistry‐aware design framework for tuning printable polydimethylsiloxane (PDMS) for vat photopolymerization (VPP) is developed using additive Gaussian process (GP) modeling. Polymer network mechanics informs variable groupings, feasible formulation constraints, and interaction variables.

Grid Forming Inverter Power Control Stability Analysis
IEEE AccessStable system operation is being actively attempted by introducing grid-forming inverters (GFMs) which mimic synchronous generators (SGs). Although the introduction of GFMs intended to replace traditional grid-following inverters (GFLs) provides system ...

Advanced Engineering Materials, EarlyView.Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...

Grid-Forming Inverters: A Critical Asset for the Power Grid
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020 Increasing inverter-based sources reduces the system’s inertia resulting in possible frequency stability issues. Understanding low-inertia systems and their stability properties is of crucial importance.

Advanced Engineering Materials, EarlyView.A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Universal Grid-Forming Method for Future Power Systems
IEEE Access, 2022 Power system inertia typically refers to the energy stored in large rotating synchronous generators. Dynamics and stability of the traditional power system is closely linked to the natural inertia of these synchronous generators. In recent years, increasing amount of synchronous generators have been replaced by high amount of different type of inverter-
