Conservation laws for non-potential operators
(1999-12-01)
A study was developed in order to build a function M invariant in time, by means of Hamiltonian's formulation, taking into account the equation associated to the problem, showing that starting from this function the equation ...
Banality of mathematical expertise
(2020-11-01)
Practices within research mathematics can and do serve as models for mathematics education. However, typically such inspirations impose a devastating narrowness in relation to reflections on mathematics. This narrowness I ...
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. ...
Ordered phases in the extended Hubbard model
(Elsevier B.V., 1994-04-02)
A novel method to probe the diverse phases for the extended Hubbard model (EHM), including the correlated hopping term, is presented. We extend an effective medium approach [1] to a bipartite lattice, allowing for charge- ...
Fuzzy mathematical morphology for color images defined by fuzzy preference relations
(Elsevier, 2016-12)
Nowadays, the representation and the treatment of color images are still open problems. Mathematical morphology is the natural area for a rigorous formulation of many problems in image analysis. Moreover, it comprises ...
On the Decomposition of Interval-Valued Fuzzy Morphological Operators
(SpringerDordrechtHolanda, 2010)
Proposição de rotina morfológica para detecção de malha viária em imagens orbitais
(2010-01-01)
The outdating of cartographic products affects planning. It is important to propose methods to help detect changes in surface. Thus, the combined use of remote sensing image and techniques of digital image processing has ...
A mathematical programming approach to applicant selection for a degree program based on affirmative action
(Informs, 2011-06)
In 2007, the Department of Industrial Engineering at the University of Chile allied with a major Chilean mining company to inaugurate a master's degree program in globalization management. The program's objective is to ...
Classification of fuzzy mathematical morphologies based on concepts of inclusion measure and duality
(SpringerDordrechtHolanda, 2008)
Multi-Lagrangians, hereditary operators and Lax pairs for the Korteweg - De Vries positive and negative hierarchies
(2003)
We present an approach to the construction of action principles (the inverse problem of the calculus of variations), for first order (in time derivatives) differential equations, and generalize it to field theory in order ...
