A Numerical method for the Viscoelastic Melt Spinning Model with Radial resolutions of Temperature and Stress Fields
(American Chemical Society, 2002-06)
A numerical method to compute the viscoelastic melt-spinning model with radial resolutions of temperature and stress fields is formulated and applied to the low speed range. The starting framework is the reduction of the ...
A comparative study between non-linear regression and artificial neural network approaches for modelling wild oat (Avena fatua) field emergence
(Cambridge University Press, 2013-01)
Non-linear regression (NLR) techniques are used widely to fit weed field emergence patterns to soil microclimatic indices using S-type functions. Artificial neural networks (ANNs) present interesting and alternative ...
Crossing the phantom divide with a classical Dirac field
(Springer, 2011-01)
In this paper we consider a spatially flat Friedmann-Robertson-Walker (FRW) cosmological model with cosmological constant, containing a stiff fluid and a classical Dirac field. The proposed cosmological scenario describes ...
Analytical solution of the mean field Ising model for finite systems
(Iop Publishing, 2012-05)
The Ising model for finite systems, e.g. for clusters of different sizes and crystal lattices, was solved analytically by the mean field approach. The magnetization was calculated from the number of accessible microstates, ...
A Discriminatively Trained Fully Connected Conditional Random Field Model for Blood Vessel Segmentation in Fundus Images
(Institute of Electrical and Electronics Engineers, 2017-01)
Goal: In this work, we present an extensive description and evaluation of our method for blood vessel segmentation in fundus images based on a discriminatively trained fully connected conditional random field model. Methods: ...
Two-dimensional cellular automaton model for the evolution of active region coronal plasmas
(Iop Publishing, 2015-02)
We study a two-dimensional cellular automaton (CA) model for the evolution of coronal loop plasmas. The model is based on the idea that coronal loops are made of elementary magnetic strands that are tangled and stressed ...
On non-homogeneous tachyon condensation in closed string theory
(Springer, 2017-08)
Lorentzian continuation of the Sine-Liouville model describes non-homogeneous rolling closed string tachyon. Via T-duality, this relates to the gauged H+ 3 Wess-Zumino-Witten model at subcritical level. This model is exactly ...
Worldline approach to the Grosse-Wulkenhaar model
(Springer, 2014-11)
We apply the worldline formalism to the Grosse-Wulkenhaar model and obtain an expression for the one-loop effective action which provides an efficient way for computing Schwinger functions in this theory. Using this ...
Non-Riemannian geometry, Born–Infeld models and trace free gravitational equations
(Elsevier B.V., 2017-08)
Non-Riemannian generalization of the standard Born–Infeld (BI) Lagrangian is introduced and analyzed from a theory of gravitation with dynamical torsion field. The field equations derived from the proposed action lead to ...
Noncommutative (generalized) sine-Gordon/massive Thirring correspondence, integrability and solitons
