Annual General Meeting 5th October 2010

NOTICE OF THE 34th ANNUAL GENERAL MEETING AND TECHNICAL MEETING

Ultrasound for the Control of Cyanobacteria by Dr. Carl Howard, The University of Adelaide

Blue-green algae (cyanobacteria) is a nuisance problem that occurs in drinking water supplies and causes problems such as bad taste and odour. In extreme cases it can cause illness to humans. This problem occurs in many fresh water supplies in Australia and around the world. The current water treatment methods for cyanobacteria are considered unsustainable and environmentally ‘friendly’ alternatives are sought. The School of Mechanical
Engineering, SA Water have developed a technique to remove algae from water using ultrasound. Recently the University of Adelaide, SA Water and other national water commissions were awarded an Australian Research Council Linkage Projects grant to further investigate methods utilising ultrasound to eliminate cyanobacteria from water supplies, and subsequently investigate the effectiveness of the technique in small and large scale water treatment test facilities. A multi-disciplinary research team has been assembled to address this issue comprising people with expertise in acoustics, vibration, and micro-biology. The presentation will cover the background issues of the problem and how ultrasound can be used in several treatment modes to treat water supplies.

Dr. Carl Howard is a lecturer and researcher from the School of Mechanical Engineering at The University of Adelaide. Dr. Howard undertakes research in a wide range of fields such as acoustics, vibration, noise control, ultrasound,
thermoacoustics, condition monitoring, digital signal processing, active noise and vibration control, kinematics and dynamics, and more. Before joining the University of Adelaide he worked at United Technologies Research
Center in Connecticut USA, Colin Gordon and Associates in California USA, Worley FEA, and Vipac Engineers and Scientists in Adelaide.

Anyone interested in attending the meeting is encouraged to join us prior to meeting for friendly dinner/drinks at Cafe Brunelli - 187 Rundle St. The technical meeting will commence at 7:30pm.

DATE: Tuesday 5th October 2010
TIME: 6:00pm Dinner, Cafe Brunelli, 187 Rundle Street 7:30pm AGM
followed by the Technical Meeting, S111, 1st Floor Engineering South Building, University of Adelaide

Presentation By Prof. Hugo Fastl on Pyschoacoustics

We were extremely fortunate to have a visit by Prof. Hugo Fastl on 31st August 2010 who gave a presentation to the Australian Acoustical Society, and the Acoustics, Vibration, and Control research group on the topic of "Basics and Applications of Psychoacoustics". The presentation was an overview of some of the main concepts in psychoacoustics, cultural differences in the interpretation of sounds, and how psychoacoustics is used in industry and research. About 30 people attended the presentation which was very well received.
