Tailoring Model‐Based Systems Engineering for Sub‐100 g PlanarSats: A Power‐First View Stack

Systems Engineering, EarlyView.
ABSTRACT This paper addresses how to apply model‐based systems engineering (MBSE) to ultrasmall planar satellites under severe power and resource constraints. PlanarSats are sub‐100‐gram spacecraft built as single printed‐circuit boards where the same surface must host both electronics and solar cells, so power generation, geometry, and component ...

Application of a Discontinuous Galerkin Method to Predict Airframe Noise [PDF]

, 2009
Unstructured grids greatly ease the mesh generation process in the case of complex geometries. The Discontinuous Galerkin Method (DGM) provides a robust, high-order accurate discretization even on this type of grid.

Comparison of surface treatment protocols for a 3D‐printable resin for definitive crowns: Effects on surface roughness and bonding performance

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to compare the effects of surface treatment protocols on the surface roughness and shear bond strength (SBS) of a three‐dimensional (3D)‐printable resin for definitive crowns. Materials and Methods A 3D‐printable resin for definitive crowns (Saremco Print Crowntec) was used to produce 168 specimens (10 × 10 × 2 mm3 ...

Unmanned Aerial Systems for Corrosion Detection: Multi‐Sensor Technologies, Challenges, and Opportunities for Next‐Generation Inspection

Quality and Reliability Engineering International, Volume 42, Issue 6, Page 3565-3583, October 2026.
ABSTRACT Corrosion remains a critical threat to the integrity and service life of infrastructure in industries such as oil, gas, construction, renewable energy, and transportation. Traditional inspection methods, being labor‐intensive, hazardous, and often subjective, fall short in addressing modern inspection demands.

Second‐Harmonic Generation Enhancement in Polar Dielectric Films via Nonlocal Longitudinal Modes and Berreman Modes

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
Nonlocal longitudinal resonances in ultrathin AlN enable thickness‐controlled harmonic matching between a resonance at the fundamental frequency and the Berreman resonance at the second‐harmonic frequency. The resulting simultaneous field enhancement at both frequencies substantially amplifies the predicted second‐harmonic response, revealing a double ...
