This article proposes a wavelet-based monitor (WBM) for grid impedance estimation, which combines transient detection scheme (WB-TDS) and estimator (WB-GIE). The WB-TDS employs the analysis of wavelet coefficients energy detecting changing, whereas WB-GIE estimates by using real-time stationary discrete packet transform associated with signal injection scheme. During triggers injecting an inter...

Objective: Cochlear implant impedances are influenced by the intracochlear position of electrodes. Herein, we present an intuitive approach to calculate tissue resistances from transimpedance recordings, ultimately enabling estimate insertion depth cochlear Methods: Electrode positions were measured in computed-tomography images 20 subjects implanted with same lateral wall model. The estimated ...

The objective of this study was to compare impedance spectroscopy with resistance measurements at a single frequency (50 kHz) for the prediction of lamb carcass composition. The impedance spectrum is usually recorded by measuring the complex impedance at various frequencies (frequency domain); however, in this study, we also applied the faster and simpler measurement in the time domain (applica...

Successful wavelet estimation is an essential step for seismic methods like impedance inversion, analysis of amplitude variations with offset and full waveform inversion. Homomorphic deconvolution has long intrigued as a potentially elegant solution to the wavelet estimation problem. Yet a successful implementation has proven difficult. Associated disadvantages like phase unwrapping and restric...

Every unimpaired person in the world walks thousands of steps every day, and has an individual gait pattern, e.g. different velocities, load conditions, surrounding/ground conditions. Unfortunately, the number of lower-limb amputees has been increasing during the last centuries and millions of people are currently affected by amputation. To restore human walking abilities, an active knee prosth...

The RHIC luminosity upgrade program aims for an increase of the polarized proton luminosity by a factor 2. To achieve this goal a significant increase in the beam intensity is foreseen. The beam coupling impedance represents a source of detrimental effects for beam quality and stability at high bunch intensities. In this paper, we evaluate the global transverse impedance in both the AGS and RHI...
