Characterization of RGB LEDs as Emitter and Photodetector for LED-to-LED Communication [PDF]

open access: yes2020 12th International Symposium on Communication Systems, Networks and Digital Signal Processing (CSNDSP), 2020
Visible Light Communication (VLC) has rapidly grown over the last decade. However, unlike RF technologies, VLC has a simplex channel since two different devices are used for transmitting and receiving. This increases the cost and complexity of the transceiver circuit when a bidirectional link is required.

To Be Led Astray?

open access: yesTSEG - The Low Countries Journal of Social and Economic History, 2022
The Dutch Drankwet (hereinafter: Liquor Act) of 1881, the result of decades of temperance activism, was met with much criticism — little had come of the national legislation’s aim to reduce the consumption of alcohol. Even so, did this also mean that little changed in the sale of alcohol? This article examines how the Liquor Act was implemented locally
