Vertical Line Array (VLA) Beam - Forming Algorithm with constant beam width.
2005
The algorithm proposed is a beam-forming algorithm. Many beam-steering and beam-forming algorithms exist and they are all based on the control of delay times between the signals driving the loudspeakers of the line array; this kind of control produces a variable beam-width depending on steering angle and frequency. In our case beam width doesn't depend on frequency and steering angle because a specific beam forming technique was applied by shading the amplitudes of signals for each element of the array according to the frequency applied. Furthermore a weighting function was utilized for spatial windowing. Spatial windowing allows reduction of secondary lobes without varying the directivity …
Translanguaging as Playful Subversion of a Monolingual Norm in the Classroom
2018
A large part of the literature on translanguaging as a pedagogical theory has explored how an inclusive multilingual pedagogy can support students from diverse linguistic and cultural backgrounds to actively participate in the classroom. While much of this literature approaches classroom translanguaging as an instructional strategy designed to promote multilingual interactional practices, we analyse how multilingual practices can also take place as subversive language play in an educational context that is driven by a monolingual norm. Our data are video-recorded lessons from secondary-level Content and Language Integrated Learning (CLIL) classrooms in Finland in which students whose L1 is …
Scientific writing for impact factor journals
2013
EASARCICAPLivre dispo. dans :hal-00832739, version 1; Publish or Perish. This old adage illustrates the importance of scientific communication; essential to research, it also represents a strategic sector for each country’s competitiveness. An often-neglected topic, scientific communication is of vital importance, with new information technologies accelerating and profoundly changing how knowledge is disseminated. The necessity of optimally disseminating experts’ findings has also become crucial to researchers, institutes and universities alike, which has prompted the recent advent of Impact Factors for the evaluation and financing of research, the goal being for scientific knowledge to be …
