Modeling Of Space-time Focusing Of Localized Nondiffracting Pulses
(Amer Physical SocCollege Park, Maryland, 2016)
Wavepackets in Boundary Layers Close to Transonic Speeds
In practical situations, natural transition determines the transition to turbulence process. Experimental evidence suggest that the wave packet evolution is related closely to natural transition. The major part of numerical ...
The Mutual Interaction between External Rossby Waves and Thermal Forcing: the Subpolar Regions
(American Meteorological Society, 2010-06)
The authors hypothesize a simple feedback mechanism between external Rossby waves and diabatic heating from convection. This mechanism could explain the large amplitude that external Rossby waves attain as they propagate ...
Streaming patterns in Faraday waves
(Cambridge University, 2017)
Waves patterns in the Faraday instability have been studied for decades. Besides therich dynamics that can be observed on the waves at the interface, Faraday waves hidebeneath them an elusive range of flow patterns —or ...
Experimental setup for measuring roll waves on laminar open channel flows
(Elsevier B.V., 2015-03-01)
Experimental studies on open channel flows are explored mostly because of their importance in validating analytical and numerical models. Although steady flows are usually measured and explored, difficulties arise in the ...
Faster male displays and less complex choice are more attractive to female fiddler crabs as they reduce search costs
Females that quickly and accurately locate and assess males can reduce their risks of predation, dehydration and heat stress while mate searching. Here we measured the accuracy and time it took female fiddler crabs, Uca ...
Simulação numérica de Roll Waves em escoamentos turbulentos
(Universidade Estadual Paulista (Unesp), 2020-01-28)
Roll waves são instabilidades que, em condições favoráveis, podem surgir em escoamentos com superfície livre e que se propagam como um trem de ondas com velocidade e comprimento bem definidos. Tais instabilidades podem ...
New parametric decays of proton beam-plasma electromagnetic waves
(Blackwell Publishing Ltd, 2002)
Ion beam-plasma interactions are the source of wave activity in several space environments. Therefore the study of these waves and their parametric decays are very important in space physics. Thus we study parametric decays ...
