Estudo da geometria do cavaco no corte com discos abrasivos
(2001-07-01)
This paper shows a research about the study of the chip's geometry generated in the diving cut-off operation, under several cutting conditions. As a result it was possible to verify tint the cutting conditions and the type ...
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 ...
Degradación y mineralización de tartrazina mediante electrooxidación. Optimización de las condiciones de operación
(Centro de Informacion Tecnologica, 2014-01-01)
In this work, the operational conditions of the tartrazine electro-oxidation (EO) process were optimized. The batch reactor used has two electrodes: one made of diamond doped with boron and the other one of titanium, working ...

Multiple Ordered Solutions for a Class of Problems Involving the 1-Laplacian Operator
(2022-04-01)
In this paper, we use minimax methods, comparison arguments, and an approximation result to show the existence and multiplicity of solutions for the following class of problems: {-Δ1v=λf(v)inΩ,v≥0inΩ,v=0on∂Ω,where Ω is a ...
CONSTRUCTING QUANTUM OBSERVABLES AND SELF-ADJOINT EXTENSIONS OF SYMMETRIC OPERATORS. III. SELF-ADJOINT BOUNDARY CONDITIONS
(SPRINGER, 2008)
This paper completes the review of the theory of self-adjoint extensions of symmetric operators for physicists as a basis for constructing quantum-mechanical observables. It contains a comparative presentation of the ...
Sectional curvature and commutation of pairs of selfadjoint operators
(Theta Foundation, 2006-04)
The space G^+ of postive invertible operators of a C*-algebra A, with the appropriate Finsler metric, behaves like a (non positively curved)symmetric space. Among the characteristic properties of such spaces, one has that ...
Additivity properties of operator ranges
(Elsevier Science Inc, 2013-12)
In the present paper we study different conditions regarding the sum of operator ranges. In particular, we find conditions on operators A, B which imply that R(A+B)=R(A)+R(B) and derive some results concerning projections.
