CURRENT CARLAB THESIS PROJECTS

We are interested in attracting undergraduate students who are considering doing postgraduate studies, particularly those who would be able to obtain an Australian Postgraduate Award (GWAM>80). The thesis projects below present a pathway forward to postgraduate studies at CARLab. As well, to encourage students, we offer $1500AUD for completion of projects resulting in high distinction.

Project Descriptions

Thesis Number Title No. of students
CAR01 Next generation audio coding 1-2
Description

Next generation audio coding involves the reproduction of spatial audio at increasing spatial resolution. For example, we would like to be able to extract second-order signals from first-order signals and side information. In this project, we explore how to accomplish spatial audio coding with higher resolution. Resources used in this project include the CARLab multichannel room acoustics simulator and the CARLab audio facility: a spherical array of 32 loudspeakers.

The project will use MATLAB as the programming language and requires an excellent command of signal processing fundamentals.

CAR02 Convex Optimisation and Microphone Arrays 1-2
Description

Convex optimisation is a new paradigm in sensor signal processing. We are one of the first laboratories to explore the application of convex optimisation to signal processing with spherical microphone arrays. In this project, we explore sound field analysis and synthesis using compressed sensing and related techniques. We will investigate signal processing improvements to source localisation and sound field reproduction. Resources used in this project include the CARLab multichannel room acoustics simulator and the CARLab audio facility: a spherical array of 32 loudspeakers.

The project will use MATLAB as the programming language and requires an excellent command of signal processing fundamentals.

CAR03 Linking Fourier-Bessel Sound Fields to Perception 1-2
Description

High Order Ambisonics (HOA) is one of the best techniques to reproduce a three-dimensional sound field. HOA relies on a Fourier-Bessel decomposition of the sound field. One of the outstanding research problems is to relate the Fourier-Bessel representation to the acoustic parameters related to binaural perception. In this project, we explore the relationship between the Fourier-Bessel representation of a sound field and binaural acoustic parameters related to sound perception. We will simulate HOA sound field reproduction and binaural sound field reproduction using the CARLab multichannel room acoustics simulator.

The project will use MATLAB as the programming language and requires an excellent command of signal processing fundamentals.

CAR04 Adapting Time Delays in Neural Spiking Networks 1-2
Description

Computational neuroscience requires complex system modelling of biological neural networks. In this project we explore neural spiking networks with adaptable time delays. We will simulate spiking neural networks using modern neural simulators and explore methods to reliably adapt the time delays of spikes.

The project may use neural simulation packages such as BRIAN or we may design our own simulator using custom software developed at CARLab. The project requires a solid background in computational modelling.

 

Thesis Number Title No. of students
CAR05 Computational Model of Binaural Auditory Processing 1-2
Description

CARLab is developing a real-time computational model of binaural auditory processing. This model allows interactive exploration of human auditory signal processing. This project will extend custom software developed at CARLab.

This project will use the C programming language and requires a solid background in C programming as well as computational modelling.

CAR06 Low Cost Bioelectronic Methods of Newborn Assessment 1-2
Description

Currently newborns are generally assessed on length and weight. There is an urgent clinical need to develop low cost diagnostics to identify newborns at risk of malnutrition and other conditions. This project will focus on electronic, optical and ultrasonic sensor development, embedded programming and signal processing. Optionally the project includes working with subjects at The Royal Prince Alfred Hospital. In addition, we can consider biomedical measurements using sensors embedded or combined with the iPhone. Refer to this Sydney Morning Herald article. Avenues of exploration include methods for recording measurement data using the iPhone audio input and also using the sensors embedded in the iPhone.

This project requires a solid background in basic electronics and some programming background. Some background in iPhone application development will be important, if considering working with the iPhone.

CAR07 Methods of Sleep Assessment and Monitoring in the Home 1-2
Description

Polysomnography is a currently an expensive procedure that requires subjects to attempt to sleep normally at a clinic with various physiological monitors attached to assess their sleep and uncover conditions such as sleep apnea. This project will focus on developing low cost sensors for sleep monitoring based on actigraphy, impedance, magnetic, optical or electrical measurements. Optionally the project includes working with The Woolcock Institute of Medical Research and their world class polysomnography setup.

This project requires a solid background in basic electronics and some programming background.

CAR08 Air Quality and Monitoring of Respiratory Function: Mitigating Health Impacts from Dust from Open, Hand Mining 1-2
Description

In collaboration with Engineers Without Boarders this project aims to use electronic sensors to assess air quality and audio sensors to assess respiratory function. Prototype development, programming and testing are required. The device may be easily integrated into a mobile phone for remote communities.

This project requires a solid background in basic electronics and some programming background.

CAR09 3D Imaging with the Microsoft Kinect 1-2
Description

As part of a current ARC Discovery Project, we are investigating mapping 3D ear shape to 3D audio filters. This project involves using the Microsoft Kinect to obtain 3D ear shape data.

This project requires a solid background in programming.

CAR10 Controlling Panoramic Video and 3D Audio with the iPad 1-2
Description

Panoramic video and panoramic video cameras are becoming more popular. However, most videos do not enable audio panning with the panoramic image. In this project, we investigate using a microphone array to include audio panning with the panoramic image. The end platform is the iPad.

This project requires a solid background in programming for the iPad.
