โœฆ Synopsis

Equations are presented and a numerical-analytical algorithm is constructed for analysing the non-linear behaviour of a circular membrane with an arbitrary meridional profile. The branch points are determined and the supercritical behaviour is investigated in the case of a specific membrane. In the case of membranes with a relatively high initial flexure due to the choice of the shape of the profile, it is established that it is possible, instead of snapping (popping) the membrane, to obtain a smooth stable transition from one axisymmetric state to a subsequent non-contiguous state through a non-axisymmetric shape deformation step proportional to the cosine of the angular coordinate.

The polarisation impedance at the interface between a bio-electrode and the electrode-jelly on the surface of a living body is non-linearly related with d.c. and a.c. current density and excitation frequency etc. Since the bio-signal has both d.c. and a.c. components, so the conventional methods of
