An Electro-Mechanical Device for Solving Non-Linear Differential Equations [PDF]

Journal of Applied Physics, 1949
This paper introduces an electro-mechanical device for solving some non-linear differential equations. Solutions are obtained with sufficient accuracy and speed so that an entire domain of solutions can be quickly investigated. The procedure not only avoids the limited point of view inherent in the solutions obtained by most mechanical means, but also ...

A Mechanical–Electrical Model to Describe the Negative Differential Resistance in Membranotronic Devices

physica status solidi (RRL) – Rapid Research Letters
Membranotronic devices are artificial neural membranes mimicing the functionality of biological neural networks. These devices rely on the emergence of negative differential resistance (NDR). A minimalistic physical model for membranotronic devices capable of generating NDR is presented.
