Energy dependence of the inelasticity in collisions from experimental information on charged particle multiplicity distributions

P. C. Beggio, F. R. Coriolano

The dependence of the inelasticity in terms of the center of mass energy is studied in the eikonal formalism, which provides connection between elastic and inelastic channels. Due…

Data-Space Inversion with Ensemble Smoother

Mateus M. Lima, Alexandre A. Emerick, Carlos E. P. Ortiz

Reservoir engineers use large-scale numerical models to predict the production performance in oil and gas fields. However, these models are constructed based on scarce and often in…

Inelastic cross sections, overlap functions and Cq moments from ISR to LHC energies in proton interactions

P. C. Beggio

We investigated the energy dependence of the parton-parton inelastic cross sections, parton- parton inelastic overlap functions and the Cq moments in proton interactions from 10 to…

Regularized Pel-Recursive Motion Estimation Using Generalized Cross-Validation and Spatial Adaptation

Vania V. Estrela, Luis A. Rivera, Paulo C. Beggio +1

The computation of 2-D optical flow by means of regularized pel-recursive algorithms raises a host of issues, which include the treatment of outliers, motion discontinuities and oc…

Adaptive mixed norm optical flow estimation

Vania V. Estrela, Matthias O. Franz, Ricardo T. Lopes +1

The pel-recursive computation of 2-D optical flow has been extensively studied in computer vision to estimate motion from image sequences, but it still raises a wealth of issues, s…

Thermodynamical Analysis of a Black Hole with a Global Monopole Within a Class of a f(R) Gravity

F. B. Lustosa, M. E. X. Guimarães, Cristine N. Ferreira +1

We analyze the thermodynamics of a black hole in a region that contains a global monopole in the framework of a particular class of a f(R) gravity. Specifically, we study the case…

Cross sections, multiplicity and moment distributions at the LHC

P. C. Beggio, E. G. S. Luna

The unitarity of the -matrix requires that the absorptive part of the elastic scattering amplitude receives contributions from both the inelastic and the elastic channels. We ex…

Oscillations of factorial cumulants to factorial moments ratio from an eikonal approach

Paulo Cesar Beggio

We study the factorial moments (Fq), the factorial cumulants (Kq) and the ratio of Kq to Fq (Hq = Kq=Fq) in pp/pp collisions using an updated approach, in which the multiplicity di…

The global solvability of initial-boundary value problem for nondiagonal parabolic systems

Wladimir Neves, Mikhail Vishnevskii

In this paper we study the quasilinear nondiagonal parabolic type systems. We assume that the principal elliptic operator, which is part of the parabolic system, has a divergence s…

Impact Parameter Dependence of Inelasticity in / Collisions

P. C. Beggio

We study the impact parameter dependence of inelasticity in the framework of an updated geometrical model for multiplicity distribution. A formula in which the inelasticity is rela…

Calibration of the Transport Parameters of a Local Problem of Water Quality in Igapó I Lake

Neyva M. L. Romeiro, Rigoberto G. S. Castro, Eliandro R. Cirilo +1

The calibration of a model refers to the process by which one can estimate some parameters by comparisons with observed data. Due to the dynamical nature of the environment, variat…

Density mismatch in thin diblock copolymer films

S. Martins, W. A. M. Morgado, M. S. O. Massunaga +1

Thin films of diblock copolymer subject to gravitational field are simulated by means of a cell dynamical system model. The difference in density of the two sides of the molecule a…
