In these lectures, we discuss three closely related topics. We first discuss derivation of the nonlinear evolution equation for surface acoustic waves and show that all known methods of derivation should and do give the same evolution equation. We th...

In a recent paper by Tanuma and Man, a two-term asymptotic formula was derived for the speed of surface waves propagating in an anisotropic elastic half-space whose elastic moduli differ only slightly from those for a (base) isotropic elastic materia...

Both reactive and deliberative qualities are essential for a good action selection mechanism. We present a model that embodies a hybrid of two very different neural network architectures inside an animat: one that controls their high level deliberati...
