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...

in exploration seismology quality factor is widely used as a seismic attribute to identify anomalies related to attenuation, especially those caused by hydrocarbon. previous studies have indicated that seismic energy loss known as attenuation is greater for high frequency components of seismic data compared to the low frequency components. here the continuous wavelet transform is used to study ...

Frequency-domain unsteady lifting-line theory is better developed than its time-domain counterpart. To take advantage of this, this paper transforms kinematics to the frequency domain, performs a convolution and then returns results back time-domain. It demonstrates how well-developed frequency-domain methods can be easily applied problems, enabling prediction forces moments on finite wings und...

to date, a number of numerical methods, including the popular finite-difference time domain (fdtd) technique, have been proposed to simulate ground-penetrating radar (gpr) responses. despite having a number of advantages, the finite-difference method also has pitfalls such as being very time consuming in simulating the most common case of media with high dielectric permittivity, causing the for...

Quantum state tomography is a basic tool in quantum information, but it becomes challenging task that requires an immense number of measurement configurations as the system dimension grows. We implement adaptive compressive scheme capable reconstructing any arbitrary low-rank spectral-temporal optical signal with extremely few settings and without ad hoc assumption about initially unknown signa...
