Spectral proper orthogonal decomposition and resolvent analysis of near-wall coherent structures in turbulent pipe flows
(2020-01-01)
Direct numerical simulations, performed with a high-order spectral-element method, are used to study coherent structures in turbulent pipe flow at friction Reynolds numbers and. The database was analysed using spectral ...
The earth's magnetosphere: a systems science overview and assessment
(Springer, 2018-09)
A systems science examination of the Earth's fully interconnected dynamic magnetosphere is presented. Here the magnetospheric system (a.k.a. the magnetosphere-ionosphere-thermosphere system) is considered to be comprised ...
Quaternionic (super) twistors extensions and general superspaces
(World Scientific, 2017-01)
In a attempt to treat a supergravity as a tensor representation, the four-dimensional NN-extended quaternionic superspaces are constructed from the (diffeomorphyc) graded extension of the ordinary Penrose-twistor formulation, ...
Monitoring molecular vibronic coherences in a bichromophoric molecule by ultrafast X-ray spectroscopy
(Royal Society of Chemistry, 2021-04)
The role of quantum-mechanical coherences in the elementary photophysics of functional optoelectronic molecular materials is currently under active study. Designing and controlling stable coherences arising from concerted ...
Elements of metacommunity structure of Paraguayan bats: multiple gradients require analysis of multiple ordination axes
(Oecologia (2009) 160:781–793, 2009-03-10)
Techniques to evaluate elements of metacommunity
structure (EMS; coherence, species turnover and
range boundary clumping) have been available for several
years. Such approaches are capable of determining which
idealized ...
Coherence as a measure for non-Markovianity and its applications to color centers in diamond
(American Physical Society, 2019-04-30)
The degree of non-Markovianity of a continuous bath can be quantified by means of the coherence. This simple measure is experimentally accessible through Ramsey spectroscopy, but it is limited to incoherent dynamical maps. ...
Atenuação de ruídos coerentes utilizando decomposição em modos empíricos
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2010-10-23)
The seismic processing technique has the main objective to provide adequate picture of geological structures from subsurface of sedimentary basins. Among the key steps of this process is the enhancement of seismic reflections ...
