A Better Story: An Embodied-Design Argument for Generic Manipulativesy, these students did not experience key struggles and insights that the designers believe to be pivotal to their conceptual development in this particular content (proportionality). Drawing on enactivist theory, we analyze several case studies qualitatively to explicate how rich situativity filters

lighted. The renormalization of transition energies in InGaAs QDs is found to be proportional to the number of excitons per dot and in the wetting layer. Resonant Raman scattering on such dots reveals localized TO- and LO-like phonon modes being blue shifted with respect to unstrained InAs bulk mode

Kevin Larkin,Todd Milfordeved by using light as the information carrier. There has been an exponential growth in the deployment and capacity of optical fibre communication technologies and networks over the past twenty-five years. This growth has been made possible by the development of new optoelectronic technologies that

The direct modulation method is represented by semiconductor laser diodes, where injection current for the laser diode is changed by signals. This has been used for a long time for lightwave transmission systems. The second method is used f

Andreas O. Kyriakides,Maria Meletiou-Mavrotheriseared in 1995 several reprints became necessary starting from 1997, one of them for the Chinese market. They contained only rather limited updates of the material and corrections. In the meantime scienti?c progress brought a lot of new results, which necessitate a new, seriously revised edition. Thi
