Comprehensive TCAD Investigation of RF Performance, Noise Characteristics, and Intrinsic Capacitances of InAlAs/InGaAs/InP HEMTs: Impact of Gate-to-Channel Distance and Gate Bias.

This study utilizes TCAD simulations to demonstrate that increasing the gate-to-channel distance in InAlAs/InGaAs/InP HEMTs generally reduces noise spectral densities and gate-to-drain capacitance while increasing output conductance and gate-to-source capacitance, whereas varying the gate bias produces distinct, often opposing, effects on current and voltage noise characteristics.

Modeling method for axial symmetric liquid storage tank sloshing equivalent parameters based on random forests

This paper proposes a rapid, high-precision modeling method for the equivalent sloshing parameters of axisymmetric liquid storage tanks using a Random Forest proxy model trained on a large-scale dataset, which significantly improves design efficiency and reveals that fill ratio and length-to-slenderness ratio are the most critical geometric factors influencing sloshing behavior.
