Rotating-disk sorptive extraction: effect of the rotation mode of the extraction device on mass transfer efficiency
(Springer-Verlag, 2014)
The extraction device used in rotating-disk sorptive
extraction consists of a Teflon disk in which a sorptive phase
is fixed on one of its surfaces. Depending on the configuration,
the rotation axis of the disk device ...
Differential rotation in rapidly rotating early-type stars. I: motivations for combined spectroscopic and interferometric studies.
(Edp Sciences, 2011-02)
Context. Since the external regions of the envelopes of rapidly rotating early-type stars are unstable to convection, a coupling may
exist between the convection and the internal rotation.
Aims. We explore what can be ...
Phase transition in the two-dimensional dipolar planar rotator model
(Journal of Physics: Condensed Matter, 2017)
Bose-Einstein condensates in rotating ring-shaped lattices: A multimode model
(IOP Publishing, 2019-12-23)
We develop a multimode model that describes the dynamics on a rotating Bose-Einstein condensate confined by a ring-shaped optical lattice with large filling numbers. The parameters of the model are obtained as a function ...
Beyond the rotating wave approximation. An intensity dependent nonlinear coupling model in two-level systems
(Elsevier Science, 2010-03)
An intensity dependent nonlinear coupling model of a two-level system interacting with a bimodal cavity field via two-photon transitions is investigated in a scenario where the rotating wave approximation is lifted. The ...
Metaheuristics for a crop rotation problem
(2014)
This paper presents a mathematical model adapted from literature for the crop rotation problem with demand constraints (CRP-D). The main aim of the present work is to study metaheuristics and their performance in a real ...
Time-dependent mass-transfer behaviour under laminar and turbulent flow conditions in rotating electrodes: A CFD study with analytical and experimental validation
(Pergamon-Elsevier Science Ltd, 2019-07)
Results of numerical calculations and their comparison with analytical expressions or experimental data under laminar and turbulent flow conditions are reported. It is predicted the transient and steady-state behaviour of ...
Mixed integer quadratically-constrained programming model to solve the irregular strip packing problem with continuous rotations
(Springer, 2018-09-01)
The irregular strip packing problem consists of cutting a set of convex and non-convex two-dimensional polygonal pieces from a board with a fixed height and infinite length. Owing to the importance of this problem, a large ...
A finite element approach for predicting the ultimate rotation capacity of RC beams
(2013-07-15)
This paper presents a numerical approach to model the complex failure mechanisms that define the ultimate rotational capacity of reinforced concrete beams. The behavior in tension and compression is described by a constitutive ...
