Measuring time-domain spectral induced polarization in the on-time: decreasing acquisition time and increasing signal-to-noise ratio

A Probabilistic Three-Phase Time Domain Electric Arc Furnace Model based on analytical method

An electric arc furnace (EAF) is known as nonlinear and time variant load that causes power quality (PQ) problems such as, current, voltage and current harmonics, voltage flicker, frequency changes in power system. One of the most important problems to study the EAF behavior is the choice of a suitable model for this load. Hence, in this paper, a probabilistic three-phase model is proposed base...

Para-Hydrogen Induced Polarization at Time Domain NMR Spectrometer

Nuclear Magnetic Resonance (NMR) is a widely used spectroscopic method in a broad range of disciplines. Unfortunately NMR suffers from a low intrinsic sensitivity. The low sensitivity of NMR can be successfully improved by application of hyperpolarization technique called Para-Hydrogen Induced Polarization (PHIP) which was discovered in 1986 [1-3]. Till now, a substantial progress in the method...

Newborn EEG Seizure Detection Based on Interspike Space Distribution in the Time-Frequency Domain

This paper presents a new time-frequency based EEG seizure detection method. This method uses the distribution of interspike intervals as a criterion for discriminating between seizure and nonseizure activities. To detect spikes in the EEG, the signal is mapped into the time-frequency domain. The high instantaneous energy of spikes is reflected as a localized energy in time-frequency domain. Hi...

A multi-domain spectral method for time-fractional differential equations

This paper proposes an approach for high-order time integration within a multi-domain setting for timefractional differential equations. Since the kernel is singular or nearly singular, two main difficulties arise after the domain decomposition: how to properly account for the history/memory part and how to perform the integration accurately. To address these issues, we propose a novel hybrid a...
