Crack‐Growing Interlayer Design for Deep Crack Propagation and Ultrahigh Sensitivity Strain Sensing

Advanced Functional Materials, EarlyView.
A crack‐growing semi‐cured polyimide interlayer enabling deep cracks for ultrahigh sensitivity in low‐strain regimes is presented. The sensor achieves a gauge factor of 100 000 at 2% strain and detects subtle deformations such as nasal breathing, highlighting potential for minimally obstructive biomedical and micromechanical sensing applications ...

Modeling Transformers with Internal Incipient Faults

IEEE Power Engineering Review, 2002
Incipient fault detection in transformers can provide early warning of electrical failure and could prevent catastrophic losses. To develop the transformer incipient fault detection technique, a transformer model is required, to simulate internal incipient faults.

Internal Combustion Engines Fault Diagnostics

2020
This article describes the methods of diagnosing internal combustion engines (ICE). The conclusion is drawn that the majority of modern methods and ICE diagnostic devices don’t solve fully a problem of determination of technical condition of the engine, often are labor-consuming and expensive. The choice of a method and mode of diagnosing of ICE on the

Modeling transformer internal faults using Matlab

11th IEEE Mediterranean Electrotechnical Conference (IEEE Cat. No.02CH37379), 2003
This paper describes a technique for modeling transformer internal faults using MATLAB. In this technique a model for simulating a two-winding-single-phase transformer is modified to be suitable for simulating an internal fault in one of the windings.
