讲座主题：“Understanding user search behaviour on mobile devices”

讲座简介：

Web search on hand-held devices has become enormously common and popular. Although a number of studies have revealed how users interact with search engine result pages (SERPs) on desktop machines, there are comparatively few studies related to user interaction in mobile web search. Search results are commonly shown in a similar way whether on a mobile phone or a desktop. Therefore, it is still difficult to know what happens between users and SERPs when searching on small screens, and this means that the current presentation of SERPs on mobile devices may not be optimal.

In this talk, four key issues will be considered: screen size for desktop monitors vs mobile devices; search behaviour on different sized small screens; horizontal viewport control in mobile web search; and the effect of snippet length on a mobile device.

The research has been conducted with a view to better understanding users mobile web search behaviour. The findings can be applied to a wide range of research areas such as information retrieval, human-computer integration, and even social science for better presentation of SERP on mobile devices.

讲座主题：“Smart Grid Optimization Supported by Data Analytics, Energy Storage and Renewables”

讲座简介：

Energy sector in most countries is undergoing a complex transition not only due to access to increasingly affordable solar technologies but also due to the increased ability to predict how electricity will be used by consumers, which then can be used to optimize the usage of non-dispatchable energy.  In Australia there are remote areas where grid electricity is not available and cost prohibitive. Therefore fully renewable off grid opportunities for houses will be a practical and sustainable solution for energy crisis and challenges facing in Australia and other countries.

We have completed some initial work including [1-5] with PhD students and industry partners.
