Improved spectral algorithm for the detection of network communities

open access: yes, 2005
We review and improve a recently introduced method for the detection of communities in complex networks. This method combines spectral properties of some matrices encoding the network topology, with well known hierarchical clustering techniques, and the ...

Secuencia de enseñanza sobre el electromagnetismo [PDF]

open access: yes, 1995
In orden to plan the teaching sequence of any physical topic, we consider essential to bear in mind three factors, at least: the scientific problems that arise from the subjects to be studied, the conceptions of the students to whom the teaching is ...

Forward Brillouin Scattering Spectroscopy in Optical Fibers with Whispering‐Gallery Modes

open access: yesAdvanced Optical Materials, Volume 12, Issue 4, February 2, 2024.
Forward Brillouin scattering (FBS) in optical fibers is being promoted as a physical mechanism for new fiber sensing concepts. It involves two copropagating optical waves and transverse acoustic mode resonances (TAMRs). This study investigates the interaction between opto‐excited TAMRs and the optical whispering‐gallery mode resonances (WGMs) supported

Aplicación de prácticas de laboratorio sobre el contenido de electromagnetismo, en el proceso de aprendizaje de los estudiantes de undécimo grado, en el colegio Rafael María Fabretto Michely, durante el segundo semestre del año dos mil doce [PDF]

open access: yes, 2011
La enseñanza de las ciencias debe ocurrir en un espacio donde las estrategias generen en los estudiantes el potenciar las capacidades para pensar y decidir autónomamente, lo cual implica que éste adquiera los instrumentos y las herramientas ...

Concepciones previas en el aprendizaje significativo del electromagnetismo [PDF]

open access: yes, 1990
Difficulties that are present in the basic conceptualizations of electromagnetism are analized. The logic way, followed in physics instruction, which is not necessarily the most adequate to initiate the study of the subject is emphasized.

La Unificación de la Física [PDF]

open access: yes, 2015
Aunque a lo largo de la historia de la Física hemos avanzado construyendo una serie de teorías parciales que expliquen diferentes fenómenos de nuestra naturaleza aparentemente independientes entre sí, sería muy difícil construir en un solo paso una ...

Interplay between crystal-size and disorder effects in the high-energy optical response of photonic crystal slabs [PDF]

open access: yes, 2007
Experimental reflectance spectra have been obtained for colloidal crystals whose widths ranged from one to several sphere monolayers, and their features in the higher order band energy range have been reproduced theoretically.
