egenerated for reuse using solar energy or other waste heat.
A number of tasks to be followed among the students in this project are:
1. Literature survey on traditional drying systems for agricultural products used
so far in Australia and other parts of the world.
2. Comparison between the above systems from the performance, energy savings
and the environmental point of view.
The project will then focus on the market potential of the liquid desiccant drying
system. The student will need to conduct a feasibility analysis including strength,
weakness, opportunities and threats (SWOT) associated with the new system. A
background in economics and business will be helpful.

Project Title: Economic assessment of utility connected PV systems
A residential grid connected PV system services the local load and exports excess
energy to the electricity network. Grid-connected PV systems offer several
advantages over stand-alone systems including savings on wiring costs due to the
capability to use existing wiring in the building, the removal of the need for storage
batteries as the grid provides a backup and the possibility of selling surplus energy.
PV systems employing batteries may also improve the reliability if loads can be
supplied during grid power interruptions. In Australia, individual utilities impose their
own regulations on the specifications required for grid interconnection. The
corresponding metering and tariff structures for energy transfer are also set by the
utilities.
While studies show that renewable energy generators and in particular PV are
technically viable using existing technology, their use in the domestic sector has
been constrained by economical and organizational barriers. The benefits of gridconnected
schemes may be seen as expressing concern for the environment,
energy credit associated with reductions in fuel consumption and an opportunity to
participate and contribute into a new technology.
This project involves computational and economic analyses of grid connected PV
systems such as payback period and net present value, as these parameters are
often required when considering an investment decision.

Project Title: Robust speaker recognition with reduced utterance duration
Speaker verification is the process of using a person’s speech signal to verify their
identity. It has many important applications in personal authentication, security and
forensics as well as others. Support vector machines (SVM) are an approach to
speaker verification that has shown some promise in recent years. This project
investigates a generalised linear discriminant sequence (GLDS) kernel as part of a
SVM speaker verification system. It also develops a new normalisation technique for
the GLDS kernel.
