Capacity Optimization and Hierarchical Robust Control Verification of Wind–Solar–Diesel Hybrid Microgrid Based on Improved Multi‐Objective Grey Wolf Algorithm

Engineering Reports, Volume 8, Issue 3, March 2026.
To address high‐altitude power transmission challenges, a composite controller was developed to suppress strong wind interference, demonstrating the effectiveness of hierarchical control in complex dynamic systems. Hardware‐in‐the‐loop experiments verified the robustness of the control algorithm, providing methodological support for developing ...

Soldering Si3N4 to Invar42 by a localized heating process

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract This study investigates the soldering process for joining silicon nitride (Si3N4), a commonly used ceramic, to Invar42, a low thermal expansion alloy. The focus lies on analyzing interfacial reactions and evaluating the bonding performance of the Si3N4—Invar42 joint.

Tutorial Overview: Numerical Synergy in Muffler Acoustic Design A Critical Comparison of TMM, FEM, and CFD Approaches for Transmission Loss Quantification

Engineering Reports, Volume 8, Issue 1, January 2026.
Experimental measurements reveal distinct performance boundaries: TMM achieves rapid convergence (< 2 dB error below 2000 Hz) but neglects 3D wave effects; FEA maintains < 10% deviation up to 3500 Hz with 90% reduced computational cost versus CFD; while transient CFD captures broadband attenuation trends despite 10× higher resource demands.

REPAIR OF A DAMAGED TURBOCHARGER

Proceedings on Engineering Sciences, 2019
he turbocharger is among the highest quality assemblies for modern internal combustion engines. Its contribution to engine operation is immeasurable – it increases the power output of the engine while indirectly reducing fuel consumption. Like all devices, turbochargers require quality maintenance as they are susceptible to failure.

Surrogate Model‐Based Optimisation Design and Rotor Stress Analysis of High‐Speed Permanent Magnet Motor

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes an efficient optimisation methodology for high‐speed permanent magnet synchronous motors by integrating a high‐accuracy Kriging surrogate model with an improved particle swarm optimisation (IPSO) algorithm. Mechanical integrity is ensured through rotor stress analysis and optimised multilayer sleeve design.

A machine‐learning interatomic potential for Si‐C‐N‐H with application to polymer‐to‐ceramic processing of polysilazanes

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract We developed a machine‐learning interatomic potential (MLIP) based on Moment Tensor Potentials for atomistic simulations in the Si‐C‐N‐H system. The MLIP was trained on ordered and disordered configurations—including crystalline phases, polymers, amorphous models, and high‐temperature ab initio molecular dynamics trajectories of chemical ...
