Microstrip circuit analog of a complex diffraction phenomenon
(American Institute of Physics, 2009)
This letter presents a methodology to reproduce at microwave frequencies the physical behavior of certain diffraction structures that have been investigated in the optics community. The methodology will be exemplified with ...

Un algoritmo de desentrelazado adaptativo con la repetición de imágenes basado en lógica difusa
(2009)
Esta comunicación presenta un interpolator temporal basado en lógica difusa que es utilizado para el desentrelazado de la señal de vídeo. El objetivo es que dicho interpolador sea capaz de aprovechar una caracterísctica ...

Inactivation of the "Sinorhizobium fredii" HH103 "rhcJ" gene abolishes nodulation outer proteins (Nops) secretion and decreases the symbiotic capacity with soybean
(Sociedad Española de Microbiología, Viguera Editores, 2006)
Se ha propuesto que las proteínas externas de nodulación (Nops) impiden la nodulación efectiva de Sinorhizobium fredii USDA257 con las sojas americanas. S. fredii HH103 nodula de forma natural tanto conlas sojas asiáticas ...

Four-body continuum-discretized coupled-channels calculations
(The American Physical Society, 2009)
The development of a continuum-bin scheme of discretization for three-body projectiles is necessary for studies of reactions of Borromean nuclei such as He6 within the continuum-discretized coupled-channels approach. Such ...

Continuidad púnica en la "Gades" republicana. La producción vascular del horno de la calle Troilo
(Universidad de Sevilla, 2007)
La excavación de un horno “de praefurnium escalonado” de pequeñas dimensiones en el casco antiguo de la actual ciudad de Cádiz matiza, gracias a la producción vascular asociada –en su gran mayoría piezas de la vajilla fina ...

Mediterranean temporary ponds as amphibian breeding habitats: The importance of preserving pond networks
(Springer Nature, 2009)
We describe the spatial and temporal variation in the main characteristics of amphibian breeding habitats in Doñana National Park (south of Spain), during two hydrologic cycles with different rainfall amounts and timing ...

Comparative depth-profiling analysis of nanometer-metal multilayers by ion-probing techniques
(ScienceDirect, 2009-04)
We examine here the depth resolution (interface width) in elemental analysis and depth profiling of complex layer systems of three ion-probing techniques, each of which has pros and cons: • Rutherford backscattering ...

Stabilization of oscillations through backstepping in high-dimensional systems
(2005-05)
This paper introduces a method for obtaining stable and robust self-sustained oscillations in a class of single input nonlinear systems of dimension n ≥ 2. The oscillations are associated to a limit cycle that is produced ...

A Hybrid Model for Dynamic Simulation of Custom Software Projects in a Multiproject Environment
(Springer, 2009)
This paper describes SimHiProS, a hybrid simulation model of software production. The goal is to gain insight on the dynamics induced by resource sharing in multiproject management. In order to achieve it the hierarchy ...
