We review systems that support the management of collaborative interaction, and propose a classification framework built on a simple model of coaching. Our framework distinguishes between mirroring systems, which display basic actions to collaborators, met ...
Pb(Zr,Ti)O-3 (PZT) and Pb(Zr,Ti,Nb)O-3 (PNZT) thin films were grown on platinized silicon substrates by r.f. magnetron sputtering followed by a post-annealing treatment. The Niobium, Nb, concentration varied from 1 to 7 at.% by increment of 1 at.%. The eff ...
We present here measurements on hexagonal cavities that have areas between 2.0 and 8.6 mu m/sup 2/. The 2D triangular lattice PBG mirrors are etched into a GaAs/AlGaAs waveguide heterostructure with 3 layers of InAs quantum dots at the centre of a 240 nm t ...
We present a tunable interference filter for infrared and visible light that scans the desired part of the optical spectrum within milliseconds. A single pixel detector measures serially the intensity at selected wavelengths. This concept: avoids expensive ...
Pb(Zr, Ti)O-3 (PZT) and Pb(Zr, Ti, Nb)O-3 (PNZT) thin films have been deposited on platinized silicon substrates by sputtering followed by a postannealing treatment. The Nb concentration in the films varied between 1 and 7 at. % with increments of 1 at. %. ...
Highly textured PZT(111), PZT(001/100) and random PZT films have been grown on Pt and RuO2 bottom electrodes by means of an in-situ, multimagnetron reactive sputtering process with three metal targets (Pb, Zr, Ti). The orientation was varied with the botto ...
We present a microspectrometer based on a tunable interference filter for infrared or visible light that scans the desired part of the spectrum within milliseconds. A single pixel detector measures serially the intensity at selected wavelengths. This conce ...

A combined PVD/PECVD process for the vacuum deposition of titaniumcontainingamorphoushydrogenatedcarbonfilms is described. Elemental compositions of the deposited films have been determined by in situ core level photoelectron spectroscopy (XPS). The long-t ...
We present numerical experiments of light scattering by a circular dielectric cylinder embedded in a stratified background, using the Greens tensor technique. The stratified background consists of two or three dielectric layers, the latter forming an anti- ...
