Split ring resonator-based left-handed coplanar waveguide
(American Institute of Physics, 2003)
Left-handed wave propagation in a CPW, coupled to split ring resonators and periodically loaded with signal-to-ground wires acting as inductors, was demonstrated. Since negative permeability and permittivity coexist only ...

Gene Ranking from Microarray Data for Cancer Classification : A Machine Learning Approach
(Springer, 2006)
Traditional gene selection methods often select the top–ranked genes according to their individual discriminative power. We propose to apply feature evaluation measure broadly used in the machine learning field and not ...

Nonnegative solutions for the degenerate logistic indefinite sublinear equation
(Elsevier, 2003-01)
The goal of this paper is to study the nonnegative steady-states solutions of the degenerate logistic indefinite sublinear problem. We combine bifurcation method and linking local subsupersolution technique to show the ...

Búsqueda secuencial de subconjuntos de atributos sobre un rankin
(Thomson-Paraninfo, 2005)
La selección de atributos es una técnica de preprocesamiento que extrae atributos relevantes del conjunto total de atributos, englobando una búsqueda de subconjuntos que mejor se ajusten a una medida de evaluación. Estas ...

Finding Defective Software Modules by Means of Data Mining Techniques
(IEEE, 2009-07)
The characterization of defective modules in software engineering remains a challenge. In this work, we use data mining techniques to search for rules that indicate modules with a high probability of being defective. ...

Study of 10Li via the 9Li(2H, p) reaction at REX-ISOLDE
(Elsevier, 2006)
The 9Li + 2H reaction has been investigated at 2.36 MeV/u at the REX-ISOLDE facility. In this Letter we focus on the 10Li + p channel which potentially holds spectroscopic information on the unbound nucleus 10Li. The ...

Identification of an extradiol dioxygenase involved in tetralin biodegradation: Gene sequence analysis and purification and characterization of the gene product
(American Society for Microbiology, 2000-02)
A genomic region involved in tetralin biodegradation was recently identified in Sphingomonas strain TFA. We have cloned and sequenced from this region a gene designated thnC, which codes for an extradiol dioxygenase required ...

Knowledge Channels: Bringing the Knowledge on the Web to Software Agents
(CEUR-WS, 2003)
In this paper, we present a new framework to extract knowledge from today’s non-semantic web. It associates semantics with the information extracted, which improves agent interoperability; it can also deal with changes ...

A new Kernel to use with discretized Temporal Series
(Edición Digital @tres, 2005-06)
In this papera new kernel, from statistical learning theory, is proposed to work with symbols chains (words) obtained from a discretization procedure of a continuous feature. Meanwhile the exact definition of the ...

An XML-Based Approach for the Automatic Verification of Software Requirements Specifications
(2001)
In this paper, we present an approach for the automatic verification of software requirements specifications. This approach is based on the representation of software requirements in XML and the usage of the XSLT language ...
