Complex Network Structure of Flocks in the Standard Vicsek Model
(Springer, 2013-09)
In flocking models, the collective motion of self-driven individuals leads to the formation of complex spatiotemporal patterns. The Standard Vicsek Model (SVM) considers individuals that tend to adopt the direction of ...
Complex network structure of flocks in the Vicsek Model with Vectorial Noise
(World Scientific, 2013-09)
In the Vicsek Model (VM), self-driven individuals try to adopt the direction of movement of their neighbors under the in°uence of noise, thus leading to a noise-driven order–disorder phase transition. By implementing the ...
Enhancement of microbial motility due to speed-dependent nutrient absorption
(IOP Publishing, 2014-01)
Marine microorganisms often reach high swimming speeds, either to take advantage ofevanescent nutrient patches or to beat Brownian forces. Since this implies that a sizable part oftheir energetic budget must be allocated ...
Space use by foragers consuming renewable resources
(Springer, 2014-05-01)
We study a simple model of a forager as a walk that modifies a relaxing substrate. Within it simplicity, this provides an insight on a number of relevant and non-intuitive facts. Even without memory of the good places to ...
Temporal correlations in the Vicsek model with vectorial noise
(Elsevier Science, 2018-07-27)
We study the temporal correlations in the evolution of the order parameter ϕt for the Vicsek model with vectorial noise by estimating its Hurst exponent H with detrended fluctuation analysis (DFA). We present results on ...
Emergence of a single cluster in Vicsek's model at very low noise
(American Physical Society, 2018-09-19)
The classic Vicsek model [Phys. Rev. Lett. 75, 1226 (1995)PRLTAO0031-900710.1103/PhysRevLett.75.1226] is studied in the regime of very low noise intensities, which is shown to be characterized by a cluster [macrocluster ...
Equilibrium and dynamical behavior in the Vicsek model for self-propelled particles under shear
(Versita, 2012-06)
The effects of an externally imposed linear shear profile in the Vicsek model of self-propelled particles is investigated via computer simulations. We find that the applied field changes in a relevant way both the equilibrium ...
Otherwise identical particles with differing, fixed speeds demix under time-reversible dynamics
(American Physical Society, 2020-06-18)
In recent years situations where elsewise identical particles demix when different degrees of freedom do not thermalize have become a research focus in nonequilibrium statistical mechanics. The majority of these models are ...
Avaliação de diferentes técnicas de pulverização com base em agricultura de precisão
(Universidade Federal de Santa MariaBrasilTecnologia em Agricultura de PrecisãoUFSMPrograma de Pós-Graduação em Agricultura de PrecisãoColégio Politécnico da UFSM, 2017-09-05)
The Precision Agriculture process proposes and implements spraying automation and control systems in agricultural machines, a system widely used and universal in the most diverse agricultural cultures. This work evaluates ...
Phase separation and emergence of collective motion in a one-dimensional system of active particles
(American Institute of Physics, 2019-04-14)
We study numerically a one-dimensional system of self-propelled particles, where the state of the particles is given by their moving direction (left or right), which is encoded by a spin-like variable, and their position. ...
