Solar Neutrino Rates, Spectrum, and its Moments : an MSW Analysis in the Light of Super-Kamiokande Results [PDF]

, 2000
We re-examine MSW solutions of the solar neutrino problem in a two flavor scenario taking (a) the results on total rates and the electron energy spectrum from the 1117-day SuperKamiokande (SK) data and (b) those on total rates from the Chlorine and ...

Analysis of High-Frequency Common Mode Component Characteristics of Common Mode Peak Voltage Suppression Method for Indirect Matrix Converter

Energies, 2022
A variety of modulation strategies for suppressing output common-mode voltage (CMV) of indirect matrix converters (IMC) have been proposed, but most of them mainly reduce the peak of CMV by 42.3%. The frequency-domain characteristics of CMV have not been

Asymptotic Analysis of Spectrum and Stability for One Class of Singularly Perturbed Neutral-Type Time-Delay Systems

Axioms, 2021
In this study, a singularly perturbed linear time-delay system of neutral type is considered. It is assumed that the delay is small of order of a small positive parameter multiplying a part of the derivatives in the system.

CMB anomalies and the effects of local features of the inflaton potential [PDF]

, 2017
Recent analysis of the WMAP and Planck data have shown the presence of a dip and a bump in the spectrum of primordial perturbations at the scales $k=0.002$ Mpc${}^{-1}$ and $k=0.0035$ Mpc${}^{-1}$ respectively. We analyze for the first time the effects a

Ablação da fibrilação atrial por cateter com radiofreqüência guiada por mapeamento espectral endocárdico dos "ninhos de FA" em ritmo sinusal Radiofrequency catheter ablation of atrial fibrillation guided by spectral mapping of atrial fibrillation nests in sinus rhythm

Arquivos Brasileiros de Cardiologia, 2007
FUNDAMENTO: Através de mapeamento espectral-(ME) endocárdico em ritmo sinusal, observam-se dois tipos de miocárdio atrial: o compacto de espectro liso e o fibrilar de espectro segmentado ("Ninho de FA" [NFA]).

Study on Fatigue Spectrum Analysis and Reliability Analysis of Multilayer Flexible Riser

Journal of Marine Science and Engineering, 2022
Multilayer composite flexible risers have been widely used in engineering. However, this type of structure is complex, as there are influences between layers. Moreover, a range of uncertain factors need to be considered in fatigue analysis. Therefore, it
