OCDMA Research

unique field-based optical communication test-bed designed and developed to investigate ultrahigh speed serial data rates transmissions and advanced Optical CDMA systems

test-bed connects CIDCOM Optics communication research laboratory at Strathclyde with the Rankine Building at Glasgow University

investigated the effects of residual dispersion on transmission channels when used by advanced optical CDMA systems

Novel technique was developed to enable control wavelength power redistribution within 2D-OCDMA codes which are based on wavelength hopping (WH) and time spreading (TS)

successfully tested in a multi user environment under real life conditions during our field trial experiments

the bit error rate measurements showed a 1.5dB improvement in the system performance

impedance spectroscopy of biological cells provides tool for monitoring cell growth and characteristics

using microelectrodes and a larger reference electrode

conducting polymers (PEDOT) electrodes instead of metal electrodes

PEDOT benefit from the material characteristic of transparency, low cost, biocompatibility, and lower interfacial impedance

enhances sensitivity

devices with Au electrodes and PEDOT electrodes in order to compare them

devices have three wells

Devices and Setup

Au electrode device PEDOT electrode Device Electronics and connector for device

Results Gold and PEDOT

comparison Gold electrodes show very

large impedance at lower frequencies compared to the PEDOT electrodes

Impedance of the gold electrode reduces the sensitivity of cell impedance measurement and increases influence of noise. Cell growth experiment on PEDOT

cells growing on the surface at three different frequencies over 3 days

changes at lower frequencies is most prominent. As cells spread and divide they will gradually cover more of the measuring electrode resulting in an increase in the impedance.

Sustainable Energy

Binding European targets of Renewable Energy (20% of all EU energy from RE sources by 2020) place specific demands on sustainable energy in the UK15% of UK energy from RE sources by 2020 This requires approximately 35% of electricity from RE

Scottish target for electricity from RE is over 30% by 2011 and 50% by 2020

Scotland has Europe’s largest onshore wind farm with 322MW at Whitelee near Glasgow
