Abstract: Automated acoustic recognition of species aims to provide a cost-effective method for biodiversity monitoring. This is particularly appealing for detecting endangered animals with a distinctive call, such as the New Forest cicada. To this end, we pursue a crowdsourcing approach, whereby the millions of visitors to the New Forest will help to monitor the presence of this cicada by means of a smartphone app that can detect its mating call. However, current systems for acoustic insect classification are aimed at batch processing and not suited to a real-time approach as required by this system, because they are too computationally expensive and not robust to environmental noise. To address this short-coming we propose a novel insect detection algorithm based on a hidden Markov model to which we feed as a single feature vector the ratio of two key frequencies extracted through the Goertzel algorithm. Our results show that this novel approach, compared to the state of the art for batch insect classification, is much more robust to noise while also reducing the computational cost.

Invited Talk at ACROSS Workshop 20132nd October 2013
I have been invited to give a talk at the 1st ACROSS Workshop on Cooperative Networked Embedded Systems, in Zagreb. The workshop, which will take place in November 2013, is funded by the EU FP7 Centre of Research Excellence for Advanced Cooperative Systems (ACROSS) project. My talk, titled "From sensors to networks: harvesting and utilising environmental energy", will discuss the role of energy harvesting in sensor nodes and sensor networks.

I Visit our Malaysian Campus to Help with Admissions28th August 2013
I have just returned from a week's visit to the University of Southampton's campus in Malaysia (USMC). The campus is part of EduCity@Iskandar Nusjaya, just a few minutes across the bridge from Singapore. I am the Senior Admissions Tutor for the EEE degree at USMC (and in the UK), and so this was a fantastic opportunity for me to find out more about the admissions process in Malaysia
During the visit, I helped with one of their Open Days, receiving many interested applicants to the campus for ... [more]
