Wave breaking and particle jets in intense inhomogeneous charged beams
(2007) [Journal article]This work analyzes the dynamics of inhomogeneous, magnetically focused high-intensity beams of charged particles. While for homogeneous beams the whole system oscillates with a single frequency, any inhomogeneity leads to ... -
Wave front propagation for a cauchy problem with a fast component
(1992) [Journal article] -
Wave length and celerity downstream from a hydraulic jump
(2019) [Journal article]It allows the estimation of other important wave characteristics such as the length and celerity. This study aims at describing the results of a relationship among the significant, mean, and peak periods of waves generated ... -
Wavelength self-calibration and sky subtraction for Fabry-Pérot interferometers : applications to OSIRIS
(2015) [Journal article]We describe techniques concerning wavelength calibration and sky subtraction to maximize the scientific utility of data from tunable filter instruments. While we specifically address data from the Optical System for Imaging ... -
A wavelet-based approach for analyzing industrial stochastic textures with applications
(2007) [Journal article]Several continuous manufacturing processes use stochastic texture images for quality control and monitoring. Large amounts of pictorial data are acquired, providing important information about both the materials produced ... -

Wavelets : uma aplicação a estimação do Núcleo de Inflação Brasileiro
(2018) [Dissertation]Wavelets são descritas como sendo capazes de dar tanto resolução em frequência como resoluçãao temporal a um sinal. Este trabalho revisa o que e o domínio da frequência em um espa co de dimensão nita, como o RN e apresenta ... -
WaveMIMO methodology : numerical wave generation of a realistic sea state
(2021) [Journal article]This paper presents a methodology that allows the numerical simulation of realistic sea waves, called WaveMIMO methodology, which is based on the imposition of transient discrete data as prescribed velocity on a finite ... -
A wavenumber selection approach for sample classification in the petroleum sector
(2015) [Work completion of graduation]In recent years, spectroscopy techniques such as Near-infrared (NIR) and Fourier Transform Infrared (FTIR) have been adopted as analytical tools in different fields. A spectrum of a sample usually has hundreds of wavenumbers, ... -
Waveroller : análise das características hidráulicas e de escoamento influentes na geração de energia elétrica por simulação numérica
(2015) [Work completion of graduation]Atualmente a busca por fontes alternativas de energia está crescendo, por outro lado, os oceanos e mares abrigam um grande potencial energético que ainda é pouco explorado. As ondas são capazes de percorrer grandes distâncias ... -

Waves in magnetized dusty plasmas with variable charge on dust particles
(2004) [Journal article]We present results obtained in recent years for wave propagation in a magnetized dusty plasma, including variable charge of the dust particles, and using a kinetic approach. Two forms of the dielectric tensor are obtained, ... -
W±-boson production in p–Pb collisions at √sNN = 8.16 TeV and Pb–Pb collisions at √sNN = 5.02 TeV
(2023) [Journal article]The production of the W± bosons measured in p–Pb collisions at a centre of-mass energy per nucleon–nucleon collision √sNN = 8.16 TeV and Pb–Pb collisions at √sNN = 5.02 TeV with ALICE at the LHC is presented. The W± bosons ... -
WCST-64 : considerações teóricas e evidências de validade
(2012) [Dissertation]A presente dissertação teve como objetivos identificar as versões mais utilizadas do WCST na literatura (Estudo 1), discutir algumas funções cognitivas relevantes para um desempenho adequado nesse instrumento (Estudo 2) e ... -
Weak and strong coupling theories for polarizable colloids and nanoparticles
(2011) [Journal article]A theory is presented which allows us to accurately calculate the density profile of monovalent and multivalent counterions in suspensions of polarizable colloids or nanoparticles. In the case of monovalent ions, we derive ... -
Weak instability of frustated fermionic models
(1997) [Journal article]We study the Almeida-Thouless instability of two fermionic models analogous to spin glasses that exhibit frustration and that were solved some time ago with a replica symmetric ansatz. In the first model (I) we consider ... -
Weak lensing and spectroscopic analysis of the nearby dissociative merging galaxy cluster Abell 3376
(2017) [Journal article]The galaxy cluster Abell 3376 is a nearby (¯z = 0.046) dissociative merging cluster surrounded by two prominent radio relics and showing an X-ray comet-like morphology. The merger system is comprised of the subclusters ... -
Weakly nonlinear ion-acoustic excitationsin a relativistic modelfor dense quantum plasma
(2016) [Journal article]The dynamics of linear and nonlinear ionic-scale electrostatic excitations propagating in a magnetized relativistic quantum plasma is studied. A quantum-hydrodynamic model is adopted and degenerate statistics for the ... -
Weakly turbulent plasma processes in the presence of inverse power-law velocity tail population
(2017) [Journal article]Observations show that plasma particles in the solar wind frequently display power-law velocity distributions, which can be isotropic or anisotropic. Particularly, the velocity distribution functions of solar wind electrons ...
