Metallo-dielectric core-shell nanospheres as building blocks for optical three-dimensional isotropic negative-index metamaterials
(Institute of Physics Publishing, 2011)
Materials showing electromagnetic properties that are not attainable in naturally occurring media, so-called metamaterials, have been lately, and still are, among the most active topics in optical and materials physics and ...

Sevilla: una experiencia exitosa de promoción de la movilidad en bicicleta en el Sur de Europa
(Universidad de Sevilla, 2011)
En apenas cuatro años la ciudad de Sevilla ha pasado de una participación marginal de la bicicleta en el conjunto de la movilidad urbana a cotas de participación en torno al 6% del reparto modal global de la ciudad. Éste ...

Fuzzy motion adaptive algorithm and its hardware implementation for video de-interlacing
(Elsevier, 2011)
Interlacing techniques were introduced in the early analog TV transmission systems as an efficient mechanism capable of halving the video bandwidth. Currently, interlacing is also used by some modern digital TV transmission ...

Alternate test of LNAs through ensemble learning of on-chip digital envelope signatures
(Springer, 2011-01-06)
This paper presents a novel and low-cost methodology for testing embedded Low Noise Amplifiers (LNAs). It is based on the detection and analysis of the response envelope of the Device Under Test (DUT) to a two-tone input ...

Improved nanopipelined RTD adder using generalized threshold gates
(Institute of Electrical and Electronics Engineers, 2011)
Many logic circuit applications of Resonant Tunneling Diodes are based on the MOnostable-BIstable Logic Element (MOBILE). Threshold logic is a computational model widely used in the design of MOBILE circuits, i.e. these ...

Microwave-induced water flow in a microchannel built on a coplanar waveguide
(AIP Publishing, 2011)
We present experimental and numerical investigations of water flow in a microsystem induced by microwave electric fields. Microwave dielectric heating induces gradients of temperature which produce spatial variations in ...

Measuring the speed of electromagnetic waves using the cross correlation function of broadband noise at the ends of a transmission line
(American Association of Physics Teachers, 2011)
When one end of a transmission line is connected to a broadband noise generator, sharp peaks are visible in the cross-correlation function of the signals at both ends of the line. The speed of the electromagnetic waves ...
