Search and retrieval method of similar plasma waveforms

open access: yesFusion Engineering and Design, 2004
Abstract Fusion plasma experiments often produce many channels of time-varying waveforms, and the assistance of a computational method to find similar waveforms could accelerate data analysis. To accelerate computer aided search, a so-called “thumb-indexed” reference will be required in the waveform database.

Algorithm for Designing Waveforms Similar to Linear Frequency Modulation Using Polyphase-Coded Frequency Modulation

open access: yesRemote Sensing
Linear frequency modulation (LFM) waveforms have been widely adopted due to their excellent performance characteristics, such as good Doppler tolerance and ease of physical implementation. However, LFM waveforms suffer from high autocorrelation sidelobes

Fluid Models for Kinetic Effects on Coherent Nonlinear Alfven Waves. II. Numerical Solutions [PDF]

open access: yes, 1996
The influence of various kinetic effects (e.g. Landau damping, diffusive and collisional dissipation, and finite Larmor radius terms) on the nonlinear evolution of finite amplitude Alfvenic wave trains in a finite-beta environment is systematically ...

Analysis of a Modern Voice Morphing Approach using Gaussian Mixture Models for Laryngectomees

open access: yes, 2012
This paper proposes a voice morphing system for people suffering from Laryngectomy, which is the surgical removal of all or part of the larynx or the voice box, particularly performed in cases of laryngeal cancer.

Two improved methods for testing ADC parametric faults by digital input signals [PDF]

open access: yes, 2009
In this paper, two improved methods are presented extending our previous work. The first one improves the results by adjusting the voltage levels of the input pulse wave stimulus.

Optimisation of practically constrained waveforms for Rician target detection with multiple‐input‐multiple‐output radar

open access: yesIET Radar, Sonar & Navigation, 2022
In this paper, the waveform design for Rician target detection with multiple‐input‐multiple‐output radar is addressed. The relative entropy between the distributions of the observations under two hypotheses is employed as the design metric.

Extracting More Data from LiDAR in Forested Areas by Analyzing Waveform Shape [PDF]

open access: yes, 2012
Light Detection And Ranging (LiDAR) in forested areas is used for constructing Digital Terrain Models (DTMs), estimating biomass carbon and timber volume and estimating foliage distribution as an indicator of tree growth and health. All of these purposes

Determination of wave intensity in flexible tubes using measured diameter and velocity [PDF]

open access: yes, 2007
Wave intensity (WI) is a hemodynamics index, which is the product of changes in pressure and velocity across the wave-front. Wave Intensity Analysis, which is a time domain technique allows for the separation of running waves into their forward and ...

Finite-Frequency SKS Splitting: Measurement and Sensitivity Kernels [PDF]

open access: yes, 2008
Splitting of SKS waves caused by anisotropy may be analyzed by measuring the splitting intensity, i.e., the amplitude of the transverse signal relative to the radial signal in the SKS time window. This quantity is simply related to structural parameters.
