Compact analogue neural network: a new paradigm for neural based combinatorial optimisation
TLDR
The authors present a new approach to neural based optimisation, to be termed as the compact analogue neural network (CANN), which requires substantially fewer neurons and interconnection weights as compared to the Hopfield net. Expand

Rational approximation of some irrational functions through a flexible continued fraction expansion
A simple method is given for the continued fraction expansion (CFE) of the irrational functions (s2+ 1)1/2, (s + 1)1/2, and s1/2with adjustable parameters. Explicit formulas are derived for the… Expand

Some exact steady-state sine wave solutions of non-uniform RC lines
The non-uniform RC line, constructed from thin resistive and dielectric films, is a promising circuit element for microminiature oscillator circuits. The differential equation for voltage or current… Expand
