A self-locking scheme for robust parametric oscillation in CMOS-compatible microring resonators

We introduce an innovative geometry for OPOs in a CMOS-compatible microring resonator that is robust against the effect of thermal fluctuations. It exploits lasing of the pump inherently positioned within the resonances of the microcavity.

Efficient out-of-band spectrum suppression in WDM-OFDM systems

We propose and experimentally demonstrate a new scheme for orthogonal frequency division multiplexing (OFDM) sidelobe suppression by inserting sidelobe suppression prefix (SSP) ahead of cyclic prefix (CP). The feasibility of the proposal is verified by both simulation and experiment.

A cluster RCT to reduce office workers' sitting time: Impact on activity outcomes

To evaluate, compared to usual practice, the initial and long-term effectiveness of a workplace intervention targeting reducing sitting on activity outcomes.Office worksites (≥1km apart) from a single organization in Victoria, Australia were cluster randomized to intervention (n=7) or control (n=7). Participants were 231 desk-based office workers (5 to 39 participants per worksite) working at least 0.6 full time equivalent. The workplace-delivered intervention addressed organizational, physical environment, and individual behavioural change to reduce sitting time. Assessments occurred at baseline, three-, and 12-months, with the primary outcome participants' objectively measured (activPAL3 device) workplace sitting time (mins/8-h workday). Secondary activity outcomes were: workplace time spent standing, stepping (light, moderate-vigorous and total) and in prolonged (≥30min) sitting bouts (h/8-h workday); usual duration of workplace sitting bouts; and, overall sitting, standing and stepping time (mins/16-h day…

Increasing transmission capacity of long-reach OFDM-PON by using hierarchical modulation

We introduce a novel modulation scheme termed hierarchical modulation to increase the transmission capacity of OFDM transmitter with limited bandwidth in a long-reach OFDM-PON. A proof-of-concept experiment is performed to verify the feasibility of our proposal.

Energy-efficient optical network units with simplified FFT operation in direct-detection OFDM PON

We propose and experimentally demonstrate simplified FFT operation to improve the energy efficiency of ONUs in OFDM PON. Our proposal can achieve an energy saving of 14.6% compared to the conventional OFDM PON.

Microbiologically influenced corrosion of copper and its alloys – a review

Microbiologically influenced corrosion (MIC) attacks various types of metals and alloys including copper and its alloys. Copper and its alloys are widely used for seawater piping system and heat exchangers because of its good resistance to corrosion combined with mechanical workability, excellent electrical and thermal conductivity, and ease in soldering and brazing. Despite the well-known toxicity of cuprous ions toward living organisms, the copper based alloys are not immune to microbial colonization and resulting MIC. Localised corrosion attack has been reported for copper alloys when used in contact with seawater. Both biotic and abiotic mechanisms have been used to explain the nature of corrosion attack on these alloys. This article reviews the different mechanisms proposed for MIC of copper alloys, the tolerance of different microorganisms towards coppers ions and its effect on subsequent microbial corrosion. In addition, the results of some of our recent experiments showing localised and/or inter-granu…
