Acoustics Scattering on Arbitrary Manifold Surfaces
We propose the use of surface subdivision as adaptive and higher-order boundary elements for solving a Helmholtz partial differential equation to calculate accurate acoustics sca...

Oscillator-AC: restoring rigour to linearized small-signal analysis of oscillators
— Standard small-signal analysis methods for circuits break down for oscillators because small input perturbations result in arbitrarily large output changes, thus invalidating f...
