Towards Monolithic Branching-Heat-Pipe Radiators Produced with Laser Powder Bed Fusion: Effects of Print Orientation and Surface Oxidation on Wick Performance

This study investigates how laser powder bed fusion print orientation and post-print oxidation affect the wicking performance of monolithic Inconel 718 heat pipe radiators, revealing that optimal orientation depends on the fabrication strategy and that oxidation significantly enhances capillary action specifically when water is used as the working fluid.

Three-year field performance of a residential grid-tied PV prosumer in Romania: measured data, seasonal yield, and statistical characterisation

This study presents a three-year field analysis of a residential grid-tied PV system in Romania, demonstrating consistent seasonal production patterns, complete self-consumption, and a statistically insignificant performance decline attributed to meteorological variability, thereby addressing the scarcity of real-world PV data in Central-Eastern Europe.

Probabilistic Liquefaction Hazard Assessment in Highly Stratified Alluvial Deposits Integrating Continuous In-Situ Profiling and Depth-Dependent Seismic Demand

This study demonstrates that relying on uniform peak ground acceleration assumptions underestimates liquefaction hazards in Kolkata's highly stratified alluvial deposits, revealing that integrating continuous in-situ profiling with depth-dependent nonlinear ground response analysis significantly increases the estimated probability of liquefaction to over 85% for loose granular layers under seismic scenarios.

Nonlinear Dynamics and Resonance Analysis of an Electromagnetically Controlled Rotor System Using HQM-Based Continuation

This study employs an extended Harmonic Quadrature Method with arc-length continuation to analyze the nonlinear dynamics of a PD-controlled flexible rotor system, revealing that proportional gain induces softening nonlinearity and chaos while derivative gain provides effective damping to restore stability, thereby offering a robust framework for designing electromagnetically controlled rotating machinery.
