Prof. Ian Fuss – Field theory models of human decision making

February 16 @ 3:00 pm - 4:00 pm
N158 Chapman Lecture Theatre, Engineering North

Abstract Engineers have a responsibility to try to ensure that the systems that they design can be safely operated by humans. Hence accurate and easily interpreted models of human decision making capabilities can be important for the design of complex systems, such as large power networks and air traffic control systems. Current cognitive models of human decision making are at best embryonic, but the engineering and scientific importance of this subject motivates the further development of these models. The models…

Dr. Irene Amerini – Image and video forensics: new trends in image forgery detection and source identification

February 27 @ 3:00 pm - 4:00 pm
EM G06

Abstract The pervasiveness of new ICT technologies has paved the way for new aggressive behaviors such as cyber-attack and cyber-bullying events. Many actions (e.g. harassment, violence instigation) are perpetrated online through social networks or messaging applications. In particular the widespread usage of smartphones has intensifies such a phenomenon: a picture is acquired and uploaded at the same time in different networks and illegal activities proliferate through abuses of such digital contents to achieve various malign objectives. In this seminar new…

IEEE AP/MTT – Dip. Ing. Stefan Burger – What you should know about coaxial-cables

February 27 @ 4:00 pm - 5:00 pm
EM G06

Abstract This presentation will cover the important aspects of coaxial-cable performance for a range of applications. These include resistive and dielectric loss, surface roughness, power handling, phase stability with temperature and bending, humidity, irradiation and practical aspects like specifying the right protection and cable handling. With this information you will be able to select the cable with lowest loss at your desired frequency, to predict if your cable can withstand the power used in your immunity test or whether arcing…

IEEE AP/MTT – Prof. Jan Hesselbarth – Millimeter-wave on-chip dielectric resonators, antennas and coupling elements

March 29 @ 3:00 pm - 4:00 pm
IW5.57, Ingkarni Wardli building

Abstract Dielectric resonators can be used for filters, as antennas, and as coupling elements between different transmission lines. In the millimeter-wave frequency range, spherical dielectric resonators are particularly attractive as they open a way for simple and precise placement on the surface of integrated circuits. This presentation discusses millimeter-wave on-chip spherical dielectric resonators in various applications, such as bandpass filters, antennas, and as coupling elements to waveguides (metallic waveguides as well as dielectric waveguides). Measurement results of prototypes operating at…

Prof. Lang White – Sonar Research with Maritime Division DST

April 20 @ 3:10 pm - 4:00 pm
S112, Engineering South

Abstract: This presentation will outline some of the research I have been doing with Maritime Division, DST over the last 5 years or so. In particular, I will concentrate on ESPRIT type algorithms for directions-of-arrival (DOA) estimation in sensor array signal processing in the presence of directional background noise. This talk will not be highly technical so is suitable for students and researchers who have a general interest in array processing including subspace and maximum likelihood based methods for DOA…

IEEE AP/MTT – Thomas Fickenscher – Impact of Off-Shore Wind Turbine on Forward Scattering of Marine Radar Signals

May 1 @ 4:00 pm - 5:00 pm
Napier 209

Abstract          Due to stronger wind speeds available on sea the majority of future wind energy projects in the EU, in China, and, most likely, in the U.S. will go offshore. Forward scattering (diffraction) of radar signals at a WT causes time-variant areas of obstacle loss (desensitation, blockage) and areas of obstacle gain behind the turbine. At the same time, rotating blades induce a time-variant phase modulation of the diffracted signal which will become apparent as an error in the measured…

IEEE AP/MTT – Benjamin Potelon – Planar and Substrate-Integrated- Waveguide Filters

May 17 @ 4:00 pm - 5:00 pm
N132, Engineering North, The University of Adelaide, North Terrace

Abstract This talk will focus on the recent advances in the design of planar Radio-Frequency filters and recent contributions to the design and realization of Substrate Integrated Waveguide Filters. This concept introduced in the early 2000 consists in burying waveguide cavities into planar substrates. This technique will be exposed and various issues linked to this aspect will be developed, from electrical performances to compacity, together with industrial applications for space applications or high frequencies perspectives for these techniques. Biography Benjamin…

Kyle Millar – Deep Learning for Classifying Malicious Network Traffic

May 25 @ 3:10 pm - 3:35 pm
S112, Engineering South

Abstract As the sophistication of cyber malicious attacks increase, so too must the techniques used to detect and classify them. Deep learning has become one of the most publicised techniques of machine learning in recent years. Its ability to draw complex inferences from data without requiring any predefined domain knowledge has allowed it to adapt to many areas of research, such as image classification, natural language processing, and self-driving cars. The recent successes of deep learning and the growing need…

IEEE AP/MTT – Prof. Sébastien Lalléchère – Strengths and Constraints of Deterministic-Stochastic Methods applied to Electromagnetic Simulations and Experiments

June 15 @ 3:00 pm - 4:00 pm
S112, Engineering South

Abstract The assessment of statistics and confidence intervals is deeply linked with electromagnetic compatibility (EMC) and electromagnetic interferences (EMI) issues. Indeed, the evaluation of margins and risks are inherent to EMC/EMI: many standards and/or guidelines require the accurate prediction of mean, standard deviation and/or extreme quantities of interest (voltages, currents, E- and H-fields, S-parameters, impedances …). It is well known that EMC/EMI testing configurations (both considering the devices under test and setups) are, by essence, complex to handle: for instance…
