“So I've been looking at a passive way to measure the foetal heart rate. You can do this either by putting electrodes on the mother and then detecting the Electric Cardiogram (ECG) signal, or by listening with microphones, which is what my research has focused on. This is more like using the Pinard – the foetal stethoscope that midwives used before the invention of Doppler ultrasound, but much more reliable and easy to use.”Paul, who previously worked at Industrial Research Limited (IRL) in Gracefield, has been collaborating with his former colleagues to develop a method of using microphones to separate out the mixture of signals emitted from the womb by using a technique called Blind Source Separation.
“This isolates the foetal heart rate from the mother's heart rate, and the background noise. It's also a more passive method of monitoring that doesn't negatively impact upon either the mother or the baby.”Paul says he and his IRL counterparts are now working closely with Wellington midwives to collect data from mothers using this less invasive method.
“We've proved the method works in the last few weeks of pregnancy, but we're hopeful that eventually we will be able to use it from when a foetus is 18 weeks. Doppler ultrasound can work from about 12-14 weeks, but the important stages are later in the pregnancy.”

Josh/VUW PhD scholarship position
Victoria University is pleased to announce a co-funded PhD scholarship position (approx NZ$35k/year for 3 years) in Software Defined Networks (SDN). The position based at Victoria University will provide research which is of practical benefit to the SDN community and the NZ networking community in particular. This may be via applied research of use and interest to REANNZ, and possibly international research partners like ESnet.
Possible research areas
Interdomain SDN (“east-west interface”): how to connect SDN networks in different administrative domains, including BGP alternatives
Optimal network design: how to design and test through the use of automated software optimal SDN based network designs based on specified constraints (Eg, number of routes, redundancy of critical links, etc)
Migration to SDN: how to migrate common ISP/carrier architectures from non-SDN to SDN (including network management)
SDN network management: how to manage an SDN network without needing legacy protocol support (Eg, streaming statistics replacing use of SNMP polling)
Systems/networking software experience preferred
Algorithm development including its software implementation

At the recent Genetic and Evolutionary Computation Conference, GECCO, Amsterdam, July 2013, they were awarded the best paper in the Genetics-based Machine Learning Track. GECCO is an Australian Research Council (ARC) A-rated conference. There were only 13 best papers awarded out of 570 submitted papers from the leading researchers worldwide.
The core idea of the work is to reuse already learnt information to solve increasingly harder problems, which the research team has shown to scale successfully to problems previously unsolved in machine learning. Surprisingly, nearly all other machine learning algorithms restart learning at the start of each new problem. This work introduces evolvable finite state machines into a problem's representation as a way of reusing cyclic building blocks, which are most appropriate for domains requiring repetitive patterns of knowledge. The work produced for the first time compact solutions that could solve any size problems in a number of important domains, such as parity problems. Evolutionary Computation is a branch of Artificial Intelligence which takes its inspiration from Darwinian ideas of survival of the fittest as multiple solutions are tested and bred with each other until the fittest survive. The research team form part of the Evolutionary Computation Research Group (ECRG), Victoria University of Wellington, which is one of the largest and most successful groups of this type in the world - currently with available doctoral places and scholarships available.
Track: Genetics Based Machine Learning
Extending Scalable Learning Classifier System with Cyclic Graphs to Solve Complex Large-Scale Boolean Problems. Muhammad Iqbal, Will N. Browne, Mengjie Zhang
(firstname.lastname@example.org; email@example.com; firstname.lastname@example.org)
Evolutionary computational techniques have had limited capabilities in solving large-scale problems, due to the large search space demanding large memory and much longer training time. Recently work has begun on automously reusing learnt building blocks of knowledge to scale from low dimensional problems to large-scale ones. An XCS-based classifier system has been shown to be scalable, through the addition of tree-like code fragments, to a limit beyond standard learning classifier systems. Self-modifying cartesian genetic programming (SMCGP) can provide general solutions to a number of problems, but the obtained solutions for large-scale problems are not easily interpretable. A limitation in both techniques is the lack of a cyclic representation, which is inherent in finite state machines. Hence this work introduces a state-machine based encoding scheme into scalable XCS, for the first time, in an attempt to develop a general scalable classifier system producing easily interpretable classifier rules. The proposed system has been tested on four different Boolean problem domains, i.e. even-parity, majority-on, carry, and multiplexer problems. The proposed approach outperformed standard XCS in three of the four problem domains. In addition, the evolved machines provide general solutions to the even-parity and carry problems that are easily interpretable as compared with the solutions obtained using SMCGP.
Daniel Akinyele has been awarded one of two student sponsorships to attend the 2014 NZ Wind Energy Conference and Exhibition, which will be held from the 14th-16th April at Te Papa Tongarewa in Wellington. In addition to presenting his proposal at the conference, Daniel will spend a day at Transpower, meeting staff and learning about the company, and about the electricity market and transmission planning and investment. Daniel’s proposal focuses on the intergration of wind power into distribution networks in New Zealand from the end-use and wider application perspectives. His research will model and simulate grid-connected micro and commercial-scale generation from residential and commercial premises respectively. It also considers microgrids connected to local grids for city-wide applications, which may also be disconnected from the network and operated independently in the event of a disaster. New Zealand probably has the most abundant wind energy resource in the world. Harnessing this natural resource for widespread distributed power generation (DPG) in New Zealand will not only provide support to the electrical network, improve the reliability and efficiency of the electricity supply and offer environmental benefits, but also aid the achievement of sustainable and future smart grid and help the government realize its goal of 90% renewable power by 2025. Daniel holds a National Diploma in Electrical and Electronic Engineering with Distinction from Osun State Polytechnic, Nigeria in 2002. He holds a First Class Degree in Electrical and Electronic Engineering from Nigeria’s Premier University, the University of Ibadan in 2008. He attended Loughborough University, UK for his Masters Degree in Renewable Energy Systems Technology, graduating with Distinction in 2010. He was a Senior Engineer in the renewable energy research group of the National Agency for Science and Engineering Infrastructure (NASENI) under the umbrella of the Federal Ministry of Science and Technology, Nigeria. He was responsible for renewable energy systems design and installation. He then joined the Department of Electrical and Information Engineering, Covenant University, Nigeria, as an assistant lecturer, teaching the fundamentals of Electrical Engineering and Network Analysis. He is currently a PhD student in the School of Engineering and Computer Science, Victoria University of Wellington, under the supervision of Dr Ramesh Rayudu.

People like to think of themselves as complex, but compared with things they are all too predictable. That’s what Winston Seah, Professor of Network Engineering in Victoria’s School of Engineering and Computer Science, has found as he leads a team of researchers working on the Internet of Things (IOT). Currently the area of internet development “the whole world is crazy about,” says Winston, IOT seeks to give everyday and other objects network connectivity so they can send and receive data. Supported by a three-year $1 million deal with telecommunication giant Huawei New Zealand, one of the aspects of IOT Winston and his team are exploring is how networks might handle the massively increased traffic such functionality would bring. “It’s already been predicted the numbers are going to exceed human connections by hundreds of thousand times or even a billion. How many smartphones can we carry? Maybe two or three—and that’s a lot. But let’s say my jacket is embedded with sensors that measure my body statistics. It could easily have 100 sensors, each sending data. Multiply that by the number of people in a city. And that’s just one application.” Then there is the variability of what is being transmitted and when. “It’s not like the internet in the past where you’re just dealing with human beings’ communications. People are creatures of habit. How we communicate tends to be the same. Whereas machines are so different. And sometimes you just can’t think what kind of data they will send and what kinds of patterns will emerge.” Winston and his team are also developing individual IOT applications such as land movement sensors that give advance warning of potential landslides, which are being trialled in the Manawatu Gorge near Palmerston North. With a glint in his eye, Winston ponders other New Zealand sensor candidates, turning the Internet of Things into “the Internet of Sheep, the Internet of Cows, the Internet of Pinot Noir vines…”
The project was one of several available to students to choose as part of a compulsory year-long project management paper, where students were asked to combine their electronics, software and networking expertise to solve a problem for an external client.
A team comprising Patrick Savill, Layne Small, Callum Gill, Miten Chauhan, Kandice McLean and Marc Laroza created a product for the New Zealand Fire Service’s Urban Search and Rescue team that simulates human behaviours for search and rescue training exercises.
All of the team members are studying Engineering, but as they are pursuing different majors, they each brought something different to the table. The project was called ‘Operation Zombie’ as it is targeted at replacing humans during training operations. Real people cannot be placed in realistically dangerous scenarios for fear of physical harm - and using dummies to simulate these scenarios is currently too expensive.
Patrick, the team’s spokesman, says they were aiming to produce a simple and cheap solution to the problem, by creating a small, self-contained motorised control box that can be operated wirelessly from a website. Instead of using a real person, the motorised box can mimic heat loss from the human body that might occur due to exposure in an emergency situation, as well as providing a realistic rescue scenario where someone is trapped in a river or under rubble. The group’s design was praised for being robust, waterproof and able to be operated at long-range.
“We had to build the hardware, configure the network, and design software to run the web page, so we were able to utilise our team members’ individual skills based on their areas of expertise”, Patrick says. “It was an enjoyable challenge with a tangible result, which is always a bonus”.
Patrick and his teammates found the project a useful platform to practise both ‘hard’ and ‘soft’ skills learnt in class.
“I used what I knew about creating printed circuit boards - equipment that supports electrical components - as well as everything I had learnt about micro-controller coding”, says Patrick. “A happy by-product of the course was getting to practise people-management and communication skills which are so valued by employers”.
The team met some hurdles along the way, including “timing, work falling behind, untested assumptions - and blowing up electronic parts!”
“It was definitely challenging”, says Patrick. “I went in imagining the utopia of a high-functioning team, perfect circumstances and rigid scheduling – but came out the other side with an intimate understanding of Murphy’s Law.”
Patrick says that despite the challenges, the project has definitely added value to his university degree.
“I now realise that the challenging projects are the ones you learn the most from”, he says. “I have learnt far more by making mistakes than I ever could have from easy successes. Now I hope to find a job where I can use my engineering skills and really make a difference in the world”.
And Patrick’s advice to future students?
“No one said Engineering was going to be easy, so to paraphrase American writer Denis Waitley, “Expect the best, plan for the worst, and prepare to be surprised!””
