Multi-group support vector machines with measurement costs a biobjective approach
(Elsevier, 2008-03)
Support Vector Machine has shown to have good performance in many practical classification settings. In this paper we propose, for multi-group classification, a biobjective optimization model in which we consider not only ...

Solving the BINPACKING Problem by Recognizer P Systems with Active Membranes
(Fénix Editora, 2004)
In this paper we present an e®ective solution to the BINPACKING problem using a family of recognizer P systems with active membranes, input membrane and external output. The analysis of the solution presented here will ...

On Descriptive Complexity of P Systems
(Springer, 2005)
In this paper we address the problem of describing the complexity of the evolution of a P system. This issue is is specially hard in the case of P systems with active membranes, where the number of steps of a computation ...

Cálculo de los factores de intensificación de tensiones generalizados en uniones adhesivas metal-composite
(AEMAC (Asociación Española de Materiales Compuestos), 2005-06)
Las uniones adhesivas entre materiales metálicos y compuestos generan puntos críticos donde la geometría y/o las propiedades de los materiales cambian bruscamente. El estado tensional que predice la Teoría de la Elasticidad ...

Performance analysis of single-slave Bluetooth piconets under cochannel interference
(IEEE Computer Society, 2004)
We present an analytical model for single-slave Bluetooth piconets when the coexistence of multiple interfering devices produces collisions. Closed-form expressions for the channel throughput and the mean packet delay are ...

The sextic oscillator as a γ-independent potential
(American Physical Society, 2004-01-01)
The sextic oscillator is proposed as a two-parameter solvable g-independent potential in the Bohr Hamiltonian. It is shown that closed analytical expressions can be derived for the energies and wave functions of the first ...

Positive solutions for the degenerate logistic indefinite superlinear problem the slow diffusion case
(University of Houston, 2003)
In this work we study the existence, stability and multiplicity of the positive steady-states solutions of the degenerate logistic indefinite superlinear problem. By an adequate change of variable, the problem is transformed ...
