12:00:00 - 15:00:00 - Graduate Teaching Ro... Education Innovation Series

As in the last few years, this year the CECS Education Development Group will be running the Teaching Quality Program (TQP) for CECS tutors and demonstrators.

The Tutor Induction is a part of the TQP. By attending a Tutor Induction, tutors will be introduced to ways of thinking about teaching, strategies for managing expectations, policies relating to teaching and learning and future professional development opportunities. The Tutor Inductions cover similar content each time and it is a requirement that all NEW College tutors attend at least one Tutor Induction.

The Tutor Induction is free and current tutors get paid to attend. Lunch will also be provided.

Please find further details including the session flyer and program at the TQP website- http://cecs.anu.edu.au/tutors

For catering purposes, please RSVP to - ed_dev@cecs.anu.edu.au

Tuesday 17 July, 2012 Dr. Uwe Helmke - Controlling networks of systems

2012-07-17 11:00:00

11:00:00 - 12:00:00 - RSISE Seminar Room, ... Systems and Control Series

This is a linear systems talk. We discuss the problem of controlling a network of arbirtarily interconnected linear dynamical agents. The transfer functions that describe the dynamics of the agents are allowed to be arbitrary strictly proper rational functions. A generalization of the Hautus criterion for controllability and observability is presented, using classical characterizations of system equivalence due to Fuhrmann and Rosenbrock. Applications include those to model reduction and sensitivity optimization. New short proofs characterizing controllability for series, parallel and feedback interconnections are given.

Thursday 21 June, 2012 Daniel Moody - The Physics of Notations: A Scientific Approach to Designing Visual Notations in IT Practice

2012-06-21 16:00:00

16:00:00 - 17:00:00 - Seminar Room (N101),... Software Engineering seminar

Visual notations are pervasively used in the IT field, and have dominated both research and practice since its earliest beginnings. They are used in all areas and all levels of practice, from IT strategic planning down to integrated circuit design. For example, UML, the industry standard language for modelling IT systems, consists of 13 related visual notations. Yet historically, researchers and notation designers have ignored or undervalued issues of visual representation. In evaluating and comparing notations, details of visual syntax are rarely mentioned. In designing notations, the majority of effort is spent defining notation semantics, with design of graphical conventions largely an afterthought.

This presentation describes a theory for visual notation design, called the Physics of Notations, as it focuses on the physical (syntactic) properties of notations rather than their logical (semantic) properties. It consists of two related theories: a descriptive (Type IV) theory, which defines how visual notations communicate, and a prescriptive (Type V) theory, which defines a set of principles for designing cognitively effective visual notations. The principles can be used to evaluate, compare, and improve existing visual notations as well as to construct new ones. The principles have been proposed as an international standard for designing visual notations across engineering disciplines, so could have implications beyond the IT field.

Friday 25 May, 2012 James Montgomery - Differential Evolution for RFID Antenna Design

2012-05-25 15:00:00

15:00:00 - 16:00:00 - RSISE Seminar Room, ... Artificial Intelligence Seminar

From the staff card in your wallet (or around your neck) to luggage passingthrough Hong Kong International Airport, radio-frequency identification(RFID) has become an essential technology for uniquely identifying items andpeople. An essential part of RFID is the convoluted, space-filling antennabelonging to the RFID tag embedded in a card or printed onto a sticker. Theshape of the antenna affects its read distance, with larger distances (forsmaller power inputs) preferred. Although these antennas have typically beendesigned by skilled engineers, recent attempts have been made to pose thedesign problem as a combinatorial optimisation problem. One of the firstapproaches used the constructive metaheuristic ant colony optimisation(ACO), as the problem of choosing an antenna path is naturally constructive.This seminar examines the application of the differential evolutionalgorithm to this problem and answers the question: how can a heuristic foroptimisation in continuous spaces be sensibly adapted to solve theinherently discrete problem of laying out an antenna?

Questions and digressions will be welcome during the presentation. Possibletopics for further discussion include: how might DE be applied to my petproblem; how and why would we apply a continuous solver to a discreteproblem; and multiobjective optimisation, including the many metrics forevaluating algorithm performance.

Friday 25 May, 2012 Professor Re-Bing Wu - Quantum Control Landscape Theory

2012-05-25 11:00:00

11:00:00 - 12:00:00 - CSIT Seminar Room, N... Systems and Control Series

This talk will give a survey over the quantum optimal control landscape theory that aims at an understanding of the mechanism behind the rapidly growing number of successes in adaptive laser control of ultrafst quantum phenomena. The theory is based on the kinematic analysis of the critical topology for typical quantum optimal control problems. The common finding is that, provided that the system is controllable, the optimal control landscapes are generally free of false traps. This provides an interpretation for the observed "ease" of adaptive laser control as the search for global optima will not be impeded by any local suboptima. The deeper understanding of the landscape may also help designing more efficient algorithms for simulation and experiments.

Thursday 24 May, 2012 Fiacre Rougieux - Impact of dopant compensation on the electrical properties of silicon for solar cell applications

2012-05-24 16:00:00

16:00:00 - 17:00:00 - Ian Ross Seminar Roo... Solar Seminar Series

The broad aim of my PhD was to contribute to a better understanding of the mechanisms limiting the efficiency of compensated silicon solar cells (containing boron and phosphorus in the bulk). Such dopant compensation is common in solar grade materials, especially in silicon from the metallurgical route, and can potentially lead to a degradation of the materials electronic properties.

We experimentally show that a thermal oxidation can create an n-type layer at the surface of compensated p-type silicon. This n-type layer is further shown to interfere with device performance and material characterization.

A new method to measure the sum of the majority and minority carrier mobility in silicon is introduced. Measurement of the influence of dopant density, injected carriers and temperature on the mobility sum are made and compared to data available in the literature.

Theoretical calculations show a relatively weak influence of the compensating impurities on the mobility. However experimental results suggest a stronger influence of compensating impurities.

The boron-oxygen defect in compensated n-type silicon is then experimentally investigated. It is shown that if not mitigated, the boron-oxygen defect leads to a strong reduction in implied VOC. The defect is also shown to be fundamentally different in compensated n-type silicon compared to p-type silicon.

Thursday 17 May, 2012 Robert Ackland - Revealed Preference in Information Networks

2012-05-17 11:15:00

11:15:00 - 12:00:00 - NICTA - 7 London Cir... NICTA SML Seminar

Revealed preference is one of the most influential concepts in economics. It provides a framework for testing whether a set of demand data (quantities of goods consumed at different prices) is consistent with the existence of a representative consumer maximising a utility function. This leads to the construction of bounds to true index numbers showing, for example, the change in the cost of living in a country between two time points or the difference in real income between two countries. In this presentation, I provide a brief introduction to revealed preference and then present my exploratory work on using revealed preference to model behaviour in information networks (e.g. Twitter, blog networks, WWW, online fora). This involves conceptualising participants in information sharing networks as agents who are making rational decisions about the consumption and production of information, subject to exogenous prices. The approach can be used to identify sets of individuals who share common preferences for consuming and producing information, allowing the construction of novel and economically-informed indexes of behaviour in information networks.

Thursday 17 May, 2012 Pei Leong - A Gaussian-sum based cubature Kalman filter for bearings-only tracking

2012-05-17 11:00:00

11:00:00 - 12:00:00 - RSISE Seminar Room, ... Applied Signal Processing Series

This seminar presents an efficient nonlinear filtering algorithm called the Gaussian-sum cubature Kalman filter for the bearings-only tracking problem. It is developed based on the recently proposed cubature Kalman filter and is built within a Gaussian-sum framework. The new algorithm consists of a splitting and merging procedure when a high degree of nonlinearity is detected. Simulation results show that the proposed algorithm demonstrates comparable performance to the particle filter with significantly reduced computational cost.
