Defining universality classes for three different local bifurcations
(2016-10-01)
The convergence to the fixed point at a bifurcation and near it is characterized via scaling formalism for three different types of local bifurcations of fixed points in differential equations, namely: (i) saddle-node; ...
Finite size scaling in the local abundances of geographic populations
(2011)
We analyzed the statistical distribution of intra-specifi c local abundances for a set North American breeding bird species. We constructed
frequency plots for every species and found that they showed long-tail power-law ...
A dynamical phase transition for a family of Hamiltonian mappings: A phenomenological investigation to obtain the critical exponents
(2015-05-31)
Abstract A dynamical phase transition from integrability to non-integrability for a family of 2-D Hamiltonian mappings whose angle, θ, diverges in the limit of vanishingly action, I, is characterised. The mappings are ...
Scaling behavior of public procurement activity
(2021)
Public procurement refers to the purchase by public sector entities—such as government departments or local authorities—of Services, Goods, or Works. It accounts for a significant share of OECD countries’ expenditures. ...
Influence of the scale range width on the determination of the hydraulic conductivity and effective porosity. The case of a porous aquifer in southern Italy

Scaling and power-laws in ecological systems
(COMPANY OF BIOLOGISTS LTD, 2005-05)
Scaling relationships (where body size features as the independent variable) and power-law distributions are commonly reported in ecological systems. In this review we analyze scaling relationships related to energy ...
Scale interactions and scaling laws in rotating flows at moderate Rossby numbers and large Reynolds numbers
(American Institute of Physics, 2009-12)
The effect of rotation is considered to become important when the Rossby number is sufficiently small, as is the case in many geophysical and astrophysical flows. Here we present direct numerical simulations to study the ...
Estudo numérico do escalonamento de um leito fluidizado circulante utilizando o conjunto simplificado das leis de escala de Glicksman
(Universidade do Vale do Rio dos Sinos, 2013-08-29)
Fluidized bed (FB) combustion has as main feature its capacity to reduce the release of pollutants in relation to conventional burning methods of pulverized fuel. Brazil has a potential in energy generation with FB through ...

The scaling mean and a law of large permanents
(2016)
In this paper we study two types of means of the entries of a nonnegative matrix: the permanental mean, which is defined using permanents, and the scaling mean, which is defined in terms of an. optimization problem. We ...
