High Field Electrical Conduction and Breakdown in Solid Dielectrics: A Signal Denoising Techniques by Wavelet Transform
One of the most important challenges of on-site partial discharge measurement is to capture the original signal in a noisy environment. The different sources of noise which includes thermal or resister noise added by the measuring circuit, signals due to electromagnetic interferences. Sophisticated and proper methods are required to detect and measured the partial discharge signals. Fortunately...
متن کاملHigh Performance Field Emitters
The field electron emission performance of bulk, 1D, and 2D nanomaterials is here empirically compared in the largest metal-analysis of its type. No clear trends are noted between the turn-on electric field and maximum current density as a function of emitter work function, while a more pronounced correlation with the emitters dimensionality is noted. The turn-on field is found to be twice as l...
متن کاملConduction disturbances caused by high current density electric fields.
During internal defibrillation, potential gradients greater than 100 V/cm occur near defibrillation electrodes. Such strong fields may cause deleterious effects, including arrhythmias. This study determined 1) the effects of such strong fields on the propagation of activation and 2) whether these effects were different for monophasic and biphasic shocks. Voltages and potential gradients during ...
متن کاملSpatiotemporally Controlled Cardiac Conduction Block Using High-Frequency Electrical Stimulation
BACKGROUND Methods for the electrical inhibition of cardiac excitation have long been sought to control excitability and conduction, but to date remain largely impractical. High-amplitude alternating current (AC) stimulation has been known to extend cardiac action potentials (APs), and has been recently exploited to terminate reentrant arrhythmias by producing reversible conduction blocks. Yet,...
