Spectrum estimation using frequency shifting and decimation
(Institution of Engineering and Technology, 2020-04)
Parametric spectral estimation techniques are widely used to estimate the parameters of sums of complex sinusoids corrupted by noise. In this work, we show that the numerical stability of the estimated frequencies not only ...
Sets or frequencies? How to help people solve conditional probability problems
(Taylor & Francis, 2011-11)
Since the 1970s, the Heuristics and Biases Program in Cognitive Psychology has shown that people do not reason correctly about conditional probability problems. In the 1990s, however, evolutionary psychologists discovered ...
Natural frequencies of thin rectangular plates with partial intermediate supports
(Plapiqui, 2004-12)
In the present study, a methodology to find natural frequencies with arbitrary precision of thin rectangular plates on linear intermediate supports and mixed boundary conditions is presented. This means that the edges are ...
A new class of signals for magnetobiology research
(Nature Publishing Group, 2019-12)
The great majority of experimental and theoretical studies in magnetobiology explored and tried to explain bioeffects on organisms (ranging from bacteria to humans) upon exposure to variable (AC) magnetic fields (MF) with ...
Natural vibrations of anisotropic plates with several internal line hinges
(Sprimger Link, 2020)
Natural frequencies of edge restrained tapered isotropic and orthotropic rectangular plates with a central free hole
(Elsevier, 2001-03)
Natural frequencies of tapered orthotropic rectangular plates with a central free hole and edges restrained against rotation and translation are studied by using orthogonal polynomials in the Rayleigh-Ritz method and ...
Influence of the nonlocal parameter on the transverse vibration of double-walled carbon nanotubes
(De Gruyter, 2015-10)
A high-order nonlocal continuum beam model is proposed, which can be applied to study the transverse vibrations of double-walled carbon nanotubes (DWCNTs), including those that could have initial deformations due to defects ...
A 55-year-old natural experiment gives evidence of the effects of changes in fire frequency on ecosystem properties in a seasonal subtropical dry forest
(John Wiley & Sons Ltd, 2019-02)
Fire frequency has been highlighted as an important component of fire effects on ecosystems; nevertheless, there is scarce information about how fire modulates changes in ecosystem properties, particularly for subtropical ...
Compact groups from semi-analytical models of galaxy formation: I. A comparative study of frequency and nature
(Wiley Blackwell Publishing, Inc, 2020-02)
Compact groups (CGs) of galaxies are defined as isolated and dense galaxy systems that appear to be a unique site of multiple galaxy interactions. Semi-analytical models (SAMs) of galaxy formation are a prime tool to ...
