Self-adjointness of two-dimensional Dirac operators on corner domains
(European Matjermatical, 2021)
We investigate the self-adjointness of the two-dimensional Dirac operator D, with quantum-dot and Lorentz-scalar delta-shell boundary conditions, on piecewise C-2 domains (with finitely many corners). For both models, we ...
Learning processes and the neural analysis of conditioning
(Pontificia Universidade Católica do Rio de JaneiroUniversidade de BrasíliaUniversidade de São Paulo, 2010)
Classical and operant conditioning principles, such as the behavioral discrepancy-derived assumption that reinforcement always selects antecedent stimulus and response relations, have been studied at the neural level, ...
Multiobjective real-time reservoir operation with a network flow algorithm

The class of n-entire operators
(IOP Publishing, 2013-01)
We introduce a classification of simple, regular, closed symmetric operators with deficiency indices (1, 1) according to a geometric criterion that extends the classical notions of entire operators and entire operators in ...
Cooperation in the iterated prisoner's dilemma is learned by operant conditioning mechanisms
(M I T Press, 2004)
The prisoner's dilemma (PD) is the leading metaphor for the evolution of cooperative behavior in populations of selfish agents. Although cooperation in the iterated prisoner's dilemma (IPD) has been studied for over twenty ...
On the loss of regularity for a class of weakly hyperbolic operators
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
In this paper we determine bounds for the optimal loss of regularity in the Sobolev scale for a class of weakly hyperbolic operators. (C) 2009 Elsevier Inc. All rights reserved.

Singular Integral Operators with Coefficients of a Special Structure Related to Operator Equalities
(2008)
In our previous works we have constructed operator equalities which transform scalar singular integral operators with shift to matrix characteristic singular integral operators without shift and found some of their ...
Fredholm Property of Matrix Wiener-Hopf plus and minus Hankel Operators with Semi-Almost Periodic Symbols
(Universidad de La Frontera. Departamento de Matemática y EstadísticaUniversidade Federal de Pernambuco. Departamento de Matemática, 2010)
Flocculation model applied to adjust operating conditions as flow changes
(2017-01-01)
Higher flows in the flocculation stage of water and wastewater treatment systems can be dealt with by adapting the operating conditions. This study investigates the changes required to maintain the flocculation efficiency. ...
