Integración de disciplinas al margen: herramientas sociológicas y filosóficas en la enseñanza de la Arquitectura Integration of disciplines at the edge: sociological and philosophical tools in teaching Architecture

Description: To connect the classroom with the real world and to integrate transversalities in the new process of the city, on the institutions’ demands and in the work as mediators that architects perform nowadays, has been integrated at architecture schools. These new requirements and responsibilities, as to d...

Tunable ultrafast nonlinear optofluidic coupler

Description: We present an optofluidic nonlinear coupler fabricated by selective filling of two strands of a photonic crystal fiber with the liquid CCl 4 which exhibits a large ultrafast Kerr nonlinearity. We demonstrate power dependent switching in this novel optofluidic device. The large thermo-optical effect ...

Stable bright and vortex solitons in photonic crystal fibers with inhomogeneous defocusing nonlinearity

Description: We predict that a photonic crystal fiber whose strands are filled with a defocusing nonlinear medium can support stable bright solitons and also vortex solitons if the strength of the defocusing nonlinearity grows toward the periphery of the fiber. The domains of soliton existence depend on the tran...

Coupling plasmons and dyakonons

Description: We study the coupling of plasmons and Dyakonov surface waves propagating at the interfaces between isotropic-birefringent-metal layered structures. Efficient coupling is shown to occur with a proper choice of the crystal birefringence, the refractive index of the isotropic medium, and the light prop...

Spatial solitons in optofluidic waveguide arrays with focusing ultrafast Kerr nonlinearity

Description: We present an optofluidic nonlinear waveguide array that is fabricated by selectively filling several strands of a photonic crystal fiber with the liquid CCl4, which exhibits a large focusing ultrafast Kerr nonlinearity. We demonstrate a power dependent formation of a spatial soliton in this novel o...

Anderson cross-localization

Description: We report Anderson localization in two-dimensional optical waveguide arrays with disorder in waveguide separation introduced along one axis of the array, in an uncorrelated fashion for each waveguide row. We show that the anisotropic nature of such disorder induces a strong localization along both a...

Tecnología de la invención: hacia una nueva tradición Technology of the invention: towards a new tradition

Author(s): Garcia-Cors, Josep
Description: Question: When the tools supplied by tradition are no longer useful to respond to new needs and new possibilities, is there a methodology to enables us to expand the imagination of architecture? Framework or theoretical perspective assumed: There has been an industrial revolution that has brought: n...

Herramientas pedagógicas para la docencia de proyectos arquitectónicos en escuelas periféricas o de nueva creación Pedagogical tools for teaching project design in outlying or newly created architectural schools

Description: In recent decades new architectural schools have appeared distributed throughout the country, some of them occupy a markedly peripheral position. This text synthesizes some of the most common problems faced by those institutions and enounces several tools that could be useful for those who teach pro...

Solitary-wave vortices in type II second-harmonic generation

Description: We find families of optical bright, vortex solitary waves in bulk quadratic nonlinear media under conditions for type II second-harmonic generation. We study the main properties of the families of solitary waves, including their stability. The vortex solitary waves are found to be azimuthally unstab...
