Demonstrating Advantages of Smart Antennas in Indoor Wireless Communications Systems. The performance of indoor wireless communications systems is adversely affected by multi-path signal propagation. When the received signal drops below a certain level, the usual practice is that the receiving station requests the transmitting device to increase its output power. An adverse effect of this action is a reduced life of battery of a portable transceiver, more power being radiating towards users and ....Demonstrating Advantages of Smart Antennas in Indoor Wireless Communications Systems. The performance of indoor wireless communications systems is adversely affected by multi-path signal propagation. When the received signal drops below a certain level, the usual practice is that the receiving station requests the transmitting device to increase its output power. An adverse effect of this action is a reduced life of battery of a portable transceiver, more power being radiating towards users and an increase of interference. The aim of this project is to demonstrate an alternative method of maintaining good quality communication link. The proposed method employs a smart antenna system to mitigate adverse effects of multi-path and interference.Read moreRead less

Summary
Australian dark matter detector for high mass axions. This project aims to provide the necessary equipment to allow an Australian Dark Matter Axion Haloscope, with significantly increased sensitivity by providing a milliKelvin environment and a 14 T magnet to drive axion-to-photon conversions. Dark matter is a fundamental component of the universe yet the nature of its composition is still unknown. There is growing evidence that it is comprised of axions, a low energy, weakly interacting particl ....Australian dark matter detector for high mass axions. This project aims to provide the necessary equipment to allow an Australian Dark Matter Axion Haloscope, with significantly increased sensitivity by providing a milliKelvin environment and a 14 T magnet to drive axion-to-photon conversions. Dark matter is a fundamental component of the universe yet the nature of its composition is still unknown. There is growing evidence that it is comprised of axions, a low energy, weakly interacting particle. The precision measurement tools developed by this project will have the potential to contribute both to the economy, via commercialisation, and to national security, via future applications to radar, communication and the development of engineered quantum systems.Read moreRead less
Electromagnetic field strength simulator (ELMO) for RF hazard assessment. There is significant community fear related to exposure to mobile telephone radiation. The computer program ELMO will be designed to accept information about all RF transmitters in the vicinity of cellular telephone towers from an existing database, and to calculate the total field strength. This will allow hazard assessment for both RF technicians working on the tower and adjacent residents.
Target Identification with Ultra-Wideband Polarimetric Radar. Radar reflecting objects resonate when electromagnetically and appropriately excited. These resonances can be extracted from the returned radar signal and used to identify the object. A simile is identifying a tuning fork from its sound rather than its image.
