Algebraic computation of some intersection D-modules
(Springer, 2006)
Let X be a complex analytic manifold, D ⊂ X a locally quasi-homogeneous free divisor, E an integrable logarithmic connection with respect to D and L the local system of the horizontal sections of E on X − D. In this ...

On Mining DOM Trees to build Information Extractors
(2011)
The Web is the largest information repository. The information it contains is usually available in human-friendly formats. Companies are interested in using this information. The problem is that they need it in structured ...

A methodology for the computer-aided cleaning of complex knowledge databases
(IEEE Computer Society, 2002)
In environments with complex cognitive structure (such as semantic web or sophisticated spatial databases for geographical information systems), classical methods for detecting anomalies can be inadequate. In this paper ...

New measurement of neutron capture resonances in 209 Bi
(American Physical Society, 2006-08-29)
The neutron capture cross section of 209 Bi has been measured at the CERN n TOF facility by employing the pulse-height-weighting technique. Improvements over previous measurements are mainly because of an optimized ...

One nucleon transfer operator and nuclear supersymmetry
(American Physical Society, 2005-01-01)
The appropriate use of the interacting boson-fermion model one nucleon transfer operator in connection with nuclear supersymmetries is discussed. We emphasize that care must be taken in using the same coupling ...

Nullification functors and the homotopy type of the classifying space for proper bundles
(Mathematical Sciences Publishers, 2005-09)
Let G be a discrete group for which the classifying space for proper G-actions is finite-dimensional. We find a space W such that for any such G, the classifying space BG for proper G-bundles has the homotopy type of the ...

Signal Sampling Based Transition Modeling for Digital Gates Characterization
(Springer, 2004)
Current characterization methods introduce an important error in the measurement process. In this paper, we present a novel method to drive the timing characterization of logic gates under variable input transition times. ...

Inclusiones diferenciales, matemática difusa y aplicaciones
(Sociedad Española de Matemática Aplicada, 2003-06)
En este trabajo diremos cómo se pueden modelar ciertos sistemas tomados de la realidad que usan conceptos propios de la Matemática Difusa (conjuntos, multifunciones e inclusiones diferenciales “fuzzy”). Consideraremos ...

El proceso inmigratorio en España y su incidencia en las estructuras demográficas actuales
(Universidad de Sevilla, Escuela Universitaria de Magisterio, 2010)
El proceso inmigratorio en España se ha intensificado notoriamente en los últimos años, de tal manera que se ha convertido en uno de los sucesos de mayor trascendencia y alcance en la sociedad española. En este estudio ...

Gate-Level Simulation of CMOS Circuits Using the IDDM Model
(IEEE Computer Society, 2001)
Timing verification of digital CMOS circuits is a key point in the design process. In this contribution we present the extension to gates of the Inertial and Degradation Delay Model for logic timing simulation which is ...
