Research at the Australian Energy Research Institute
Ricardo Aguilera, The University of New South Wales
The Australia Energy Research Institute (AERI) is a sustainable energy think tank that focuses on transforming energy research into practical applications. The Institute builds upon 30 years of energy research leadership at the University of New South Wales (UNSW) and has launched coordinated strategies to address every level of the energy challenge. The AERI focus is directed towards key areas such as renewable and sustainable energy systems, the creation of smart electricity grids, and the development of alternative fuels. In this presentation, an overview of the research activities carried out at the AERI is given. Here, the centre organization and the main research areas
are presented.

Rapid development within the biomedical engineering field, especially Brain-Neural-Computer Interaction (BNCI) area, provides a solid technological base for new implicit interaction based applications aimed at novel entertainment paradigms (Subtopic1) or for improving health and quality of life (Subtopic2).

Subtopic1: "Cinema and neuroscience: recent research and future applications". Current neuroscience research increasingly relies on naturalistic experimental stimuli and taps into different temporal scales of our perceptual, cognitive and emotional experiences. Both virtual reality scenarios and cinematic materials are used for such experiments. These neurocinematic  studies often use inter-subject correlations of brain activity to assess film-viewing experiences. When combined with interactive cinema technologies, real-time brain imaging allows for implicit and unconscious interaction with audio-visual media. In such  "enactive" systems, changes in the psychophysiological reactions of viewers (enactors) can determine the content in the presented narrative. Besides entertainment, such neurocinematic applications provide an excellent tool for various research topics including social and second-person neuroscience.

Subtopic2: "B-Reactable: multimodal tabletop system  for collaborative physiology monitoring and training". In B-reactable project (2013-2015), we are designing, validating and optimizing a novel multimodal system - B-Reactable - linking a tangible musical tabletop interface with BNCI technology for collaborative physiology monitoring and training in future health and professional applications. This interdisciplinary research project is based on the joint pilot work with Prof. Jorda and Sebastian Mealla, University of Pompeu Fabra, Barcelona, started in 2010. In the envisioned B-Reactable applications, users will explicitly or implicitly learn to monitor and control their physiological signals using tangible objects, and hence, understand and influence their cognitive or emotional states.

Sobre el invitado

Dr. Aleksander Väljamäe
Principal research fellow
Department of Behavioural Sciences and Learning
Linköping University, Sweden.

Aleksander Väljamäe received his PhD in applied acoustics at Chalmers University of Technology, Gothenburg, Sweden, in 2007. During his PhD studies concerning multisensory perception he was a visiting researcher at University of Barcelona and NTT Communication Science Labs, Japan. In 2007-2010 he was a postdoctoral fellow and the psychophysiology lab director at SPECS Laboratory, Universitat Pompeu Fabra, Barcelona, Spain. In 2010-2011 he was a senior postdoctoral fellow at Neuropsychology Laboratory, University of Graz, and Graz BCI lab, Technical University of Graz, Austria. Currently he is a principal research fellow (Marie Curie IOF) at Department of Behavioural Sciences and Learning, Linköping University, Sweden. He has been active in a number of EU funded projects: POEMS, PRESENCCIA, BrainAble, TOBI, Future BNCI, CONTRAST and GALA; and as an external expert for EC. His psychophysiology research concerns how audiovisual media influence humans on perceptual, cognitive and emotional levels, with particular stress on the novel methods for diagnosis and treatment of various brain disorders (e.g. autism, depression, migraine) and new applications (Brain-Computer Interfaces, neurocinema). Dr. Väljamäe also participate actively in art and science projects, e.g., his technical directing of the “Multimodal Brain Orchestra” performance in 2009, Prague  (http://news.bbc.co.uk/2/hi/science/nature/8016869.stm), and supporting video roadmapping activities of Future BNCI project (https://vimeo.com/26976145).

The Matrix Converter concept was first published in the 1970‟s, but the advantages of the topology in terms of weight and volume have yet to find widespread applications in industry. In this presentation the advantages and disadvantages of the topology will be explored and a full range of direct AC/AC power converter topologies will be introduced including two-stage Matrix
Converters and Multi-level Matrix Converters. Enabling techniques and strategies for Matrix Converter modulation, current commutation and circuit protection will be explained. The presenation
will also consider the technology required for the successful design, construction and testing of Matrix Converters as well as considering the emerging applications for this power converter
circuit. The presentation will draw on examples of hardware as well as the large pool of knowledge and experience from the team at the University of Nottingham, including a SiC JFET Matrix
Converter demonstrating >20kW/Litre.

This presentation will introduce the More Electric Aircraft concept and investigate the potential benefits of the technology for manned, civilian aircraft. Typical aircraft electrical

power systems, electrical power generation arrangements and associated aircraft loads will be described as well as the exciting, future challenges for the aerospace industry. The importance
of power electronics as an enabling technology for this step change in aircraft design is considered and examples of typical system designs are discussed.  Work undertaken at Nottingham on
Actuation for Helicopters and Power Converters for Fuel Cell applications as part of the Clean Sky JTI programme will be described and future challenges for academia and industry will be 
discussed.

Titulo: A port-Hamiltonian formulation of a 2D boundary controlled acoustic system.
Resumen/Abstract: This talk deals with the port Hamiltonian formulation of a 2D boundary controlled acoustic system. The system under consideration consits of an acoustic wave traveling in a tube equipped with a network of microphones/loudspeakers. The purpose of this smart skin is to damp the acoustic wave and reduce its effect at the output of the tube.. The overall system (wave+actuators/sensors) is finally expressed as a port Hamiltonian control system and a stabilizing distributed control law is proposed.

Biografía: Hector Ramirez received the degrees in Electronic Engineering and Master in Engineering Science from the University of Concepcion, Chile in 2006 and 2009 respectively. In 2012 he received the Doctor degree in Engineering Sciences from the University of Concepcion, Chile and the Doctor degree in Automatic Control from the University Claude Bernard - Lyon 1, France. He held a postdoc position at the department of Automatique et Systèmes Micro-Mécatroniques at FEMTO-ST, in Besançon, France. He is currently associate professor at the University of Franche-Comté. His research concerns the modelling and control of complex physical systems using energy based approaches. More specifically, it focuses on the use of port-Hamiltonian system for the structural modelling and control of systems described by ordinary and partial differential equations arising from different physical domains. The main applications of his research activities are micro/nano-electromechanic and thermodynamic systems. He is member of  the IFAC Technical Committee on Non-linear Control Systems (TC2.3) since September 2014.
