ABSTRACT This study shows the first successful fabrication of a carbon fiber‐reinforced silicon carbide (C/C‐SiC) via the liquid silicon infiltration process using two thermoplastic polyetherketoneketone (PEKK) powders as carbon precursors. Samples are analyzed after each processing step and compared to polyetheretherketone (PEEK)‐derived reference ...

Abstract Brain tumour segmentation employing MRI images is important for disease diagnosis, monitoring, and treatment planning. Till now, many encoder‐decoder architectures have been developed for this purpose, with U‐Net being the most extensively utilised. However, these architectures require a lot of parameters to train and have a semantic gap. Some

Optimising PID Controllers for Multi‐Area Automatic Generation Control With Improved NSGA‐II
ABSTRACT Modern automated generation control (AGC) is increasingly complex, requiring precise frequency control for stability and operational accuracy. Traditional PID controller optimisation methods often struggle to handle nonlinearities and meet robustness requirements across diverse operational scenarios.
