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, ...
Comparative field test between two sugar cane (Saccharum spp.) harvesters under two different operational conditions in Brazil
The sugar cane crop is one of the main products in Brazil and according to several authors can generate, besides the industrialized stalks, an amount of crop residues from the order of 15 to 30 % in weight of the aerial ...
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 ...
Multiobjective real-time reservoir operation with a network flow algorithm
(Amer Water Resources AssocMiddleburgEUA, 2001)
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 ...
A set of linear equations to calculate the steady-state operation of an electrical distribution system
In this paper, the calculation of the steady-state operation of a radial/meshed electrical distribution system (EDS) through solving a system of linear equations (non-iterative load flow) is presented. The constant power ...
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.
