Minimally Supported Frequency (MSF) d-Dilation Wavelets [PDF]

open access: yesMathematics, 2021
In this paper, we provide a geometric construction of a symmetric 2n-interval minimally supported frequency (MSF) d-dilation wavelet set with d∈(1,∞) and characterize all symmetric d-dilation wavelet sets. We also provide two special kinds of symmetric d-dilation wavelet sets, one of which has 4m-intervals whereas the other has (4m+2)-intervals, for m ...

Accident Frequency Evaluation to Support Dynamic Risk Studies [PDF]

open access: yesChemical Engineering Transactions, 2016
The safety enhancement of Oil&Gas offshore operations asks for improvements in the currently applied tools for risk estimation and evaluation. The present contribution is addressed at the development of a method for the dynamic evaluation of hydrocarbon leaks frequency from process equipment and piping.

Population scale data reveals the antidepressant effects of ketamine and other therapeutics approved for non-psychiatric indications. [PDF]

open access: yes, 2017
Current therapeutic approaches to depression fail for millions of patients due to lag in clinical response and non-adherence. Here we provide new support for the antidepressant effect of an anesthetic drug, ketamine, by Inverse-Frequency Analysis of ...

Effect of sparsity-aware time–frequency analysis on dynamic hand gesture classification with radar micro-Doppler signatures [PDF]

open access: yes, 2018
Dynamic hand gesture recognition is of great importance in human-computer interaction. In this study, the authors investigate the effect of sparsity-driven time-frequency analysis on hand gesture classification.

Distributed energy frequency–voltage support technology

open access: yesEnergy Reports, 2023
With the development of distributed energy, the penetration rate of power electronic devices is increasing, and the dominance of thermal power generation will be slowly replaced by it. Synchronous generators, which are mainly thermal power generation, will also be slowly reduced with the development of new energy.

Apparent mass of small children: Experimental measurements [PDF]

open access: yes, 2004
A test facility and protocol were developed for measuring the seated, vertical, whole-body vibration response of small children of less than 18 kg in mass over the frequency range from 1 to 45 Hz.

Detection of cochlear hearing loss applying wavelet packets and support vector machines [PDF]

open access: yes, 2004
The aim of this paper is to evaluate the application of the wavelet packet transform (WP) and support vector machines (SVM) to transient evoked otoacoustic emissions (TEOAE) in order to achieve a detection of frequency-specific hearing loss. We introduce

Temperature dependence of the frequency and noise of superconducting coplanar waveguide resonators [PDF]

open access: yes, 2008
We present measurements of the temperature and power dependence of the resonance frequency and frequency noise of superconducting niobium thin-film coplanar waveguide resonators carried out at temperatures well below the superconducting transition (Tc=9 ...
