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 [PDF]

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.

Iso-osmotic contrast filling of an artificial urinary sphincter is a safe and effective tool for diagnosis of mechanical failure [PDF]

Investigative and Clinical Urology
Purpose: Recurrent stress incontinence (SUI) in patients with an artificial urinary sphincter (AUS) is a diagnostic challenge. History, physical exam and office cystoscopy are often inadequate for determining the cause of device related issues.

Fluid Flow Mechanical Stimulation-Assisted Cartridge Device for the Osteogenic Differentiation of Human Mesenchymal Stem Cells [PDF]

Micromachines, 2021
Human mesenchymal stem cells (hMSCs) have the potential to differentiate into different types of mesodermal tissues. In vitro proliferation and differentiation of hMSCs are necessary for bone regeneration in tissue engineering. The present study aimed to design and develop a fluid flow mechanically-assisted cartridge device to enhance the osteogenic ...

Electrostatic Circular Membrane MEMS: An Approach to the Optimal Control

Computation, 2021
The recovery of the membrane profile of an electrostatic micro-electro-mechanical system (MEMS) is an important issue, because, when an external electrical voltage is applied, the membrane deforms with the risk of touching the upper plate of the device ...
