Spectral estimation of terahertz time-domain signals using a simple parametric method
(Institution of Engineering and Technology, 2015-12)
A simple method for spectral estimation of terahertz signals using an autoregressive model is developed. The technique shows a better spectral variance and resolution over the use of the Fast Fourier Transform, which is ...
A Comparative Study of Time Domain Compressed Sensing Techniques for Optoacoustic Imaging
(Institute of Electrical and Electronics Engineers, 2022-04)
Speeding up data acquisition and reducing the complexity of the detection system are among the central goals for advancing optoacoustic imaging. In this way, new reconstruction algorithms using the compressed sensing (CS) ...
Some considerations for different time-domain signal processing of pulse compression radar
(Editrice Compositori Bologna, 2010-09)
Radar technology has for a long time used various systems that allow detection under high-resolution conditions, while emitting at the same time low peak power. Among these systems, transmitted pulse encoding by means of ...
Intermittent collective dynamics of domain walls in the creep regime
(American Physical Society, 2018-12)
We study the ultraslow domain-wall motion in ferromagnetic thin films driven by a weak magnetic field. Using time-resolved magneto-optical Kerr effect microscopy, we access to the statistics of the intermittent thermally ...
Determination of the technical state of suspension elements based on the OMA-LSCE method
(Collegio Ingegneri Ferroviari Italiani, 2012-01-01)
A study is established regarding the behavior of the vehicle under the influence of the damping elements, proposing a methodology for the validation of the technical state of the dampers through the registration of dynamic ...

(Collegio Ingegneri Ferroviari Italiani, 2012-01-01)
A study is established regarding the behavior of the vehicle under the influence of the damping elements, proposing a methodology for the validation of the technical state of the dampers through the registration of dynamic ...
Domain size polydispersity effects on the structural and dynamical properties in lipid monolayers with phase coexistence
(Royal Society of Chemistry, 2018-02-10)
In lipid monolayers with phase coexistence, domains of the liquid-condensed phase always present size polydispersity. However, very few theoretical works consider size distribution effects on the monolayer properties. ...
Estimation of domains of attraction: A global optimization approach
(Pergamon-Elsevier Science Ltd, 2010-08)
In this paper a methodology for the estimation of domains of attraction of stable equilibriums based on maximal Lyapunov functions is proposed. The basic idea consists in finding the best level set of a Lyapunov function ...
Near-field asymptotics for the porous medium equation in exterior domains: The critical two-dimensional case
(Society for Industrial and Applied Mathematics, 2018-09)
We consider the porous medium equation in an exterior two-dimensional domain that excludes a hole, with zero Dirichlet data on its boundary. Gilding and Goncerzewicz proved in 2007 that in the far-field scale, which is the ...
