D. Scholten, Decentralised cascaded PV inverters: A comparison between one and two stage systems, 12th November 2015.
Abstract: Compared with parallel photovoltaic (PV) micro inverters, cascaded AC module integrated converter (MIC) systems have the added advantages of multilevel waveform switching and higher conversion efficiencies due to the absence of high gain voltage boost requirements. However, traditional centralised operation of the cascaded system is not possible due to wiring & installation cost […]
Abstract: The scalable system belongs to a class of systems whose scales can grow. In applications of large systems, such property can help the system components perform steadily and efficiently. Similarly for scalable formations, the sizes can adjust to a varying number of vehicles. Application examples include robotics, UAVs, and exploration through unknown environments. […]
Assoc. Prof. T. Matsui, Active terahertz and microwave metamaterials utilizing organic π-conjugated materials, Friday 23rd October 2015.
Abstract: In recent years, metamaterials are actively studied since novel optical functionalities cannot be accessible by nature materials come to real. To develop active metamaterials is one of extensively studied topics and we are working on developing active terahertz (THz) and microwave metamaterials utilizing organic π-conjugated materials. In this talk, I will show our […]

Abstract: Street is a reconfigurable parallel computer architecture. It executes a production language directly in hardware with the aim of realising advanced cognitive agents in a more energy efficient manner than conventional computers. Street requires frequent communication between many processing elements and to make this communication more energy efficient, a network-based communication platform, StreetNet, […]
L.B. White, Cramer-Rao Bounds and Maximum Likelihood Estimation for Narrowband Temporally Correlated Gaussian Signals Incident on a Sensor Array, 8th October 2015.
Abstract: This presentation considers modelling and estimation for narrowband sensor array processing in the presence of temporal signal correlation. When the incident signals are spatially uncorrelated, we derive a spatio-temporal signal model based on Kronecker calculus. For the Gaussian case, we derive formulae for the Cramer-Rao bounds for the angles-of-arrival and signal parameters. The […]
Prof. Ahmed Kishk, UWB Antennas for Wireless Communication and Detection Applications, 19th August 2015.
You are cordially invited to the following IEEE AP-S Distinguished Lecture hosted by the IEEE South Australia Chapter on AP-MTT & CAES ABSTRACT Ultra-wide band (UWB) wireless communication occupies a bandwidth from 3.1 to 10.6 GHz, referred to as UWB band, to achieve high data rate over a short distance. Two competing schemes, namely multiband […]
Prof. Madhu S. Gupta, Microwave Engineering: What is it, where is it headed, and how it serves the mankind, 6th August 2015
You are cordially invited to the following IEEE MTT-S Distinguished Lecture hosted by the IEEE South Australia Chapter on AP-MTT ABSTRACT What is RF and Microwave Engineering: how and why it is different from low-frequency or optical engineering; what are its theoretical underpinnings; to what applications is microwave engineering put, and what makes microwaves particularly […]
Abstract: Micron-scale passive grounded quarter-wave electric monopole antennas can be constructed by direct-drawing a polymer into micropillars, prior to metallisation. This technique is proposed for the realisation of a homogeneous 2D array of passive electric monopoles, with an operating frequency of 0.5 THz, that couples obliquely.

Q. Zhang – A Flexible Method for Calculating First- & Second-Order Eigenvalue Sensitivities in Large Power System Models – 25th June, 2015.
Abstract: A new methodology to compute the sensitivity of eigenvalues due to the change of any parameter in the model of a large modern interconnected power system is presented. Two types of parameter are considered: those which affect the initial operating state of the system are referred to as dependent parameters, whereas those that […]
