Madhulika Tripathi – Tokenised dynamic double auctions for spectrum allocation

October 13, 2016 @ 4:00 pm - 5:00 pm
Lower Napier Theatre LG29,

Abstract: The practice of formal allocation of pre-decided frequencies for specific purposes has been in existence for over a century. The rapid growth and acceptance of wireless technology-based services means that the allocation itself has come to be a significant revenue generator for governments – auction being the most lucrative mechanisms of all. Recent technical advances in area of dynamic and even opportunistic accessing spectrum have posed a challenge to the status quo. The dubious possibility of ‘spectrum crunch’ has only…

Fatima El-Hamad – Transfer Entropy Analysis of Linear Model Residuals

October 20, 2016 @ 4:00 pm - 5:00 pm
Lower Napier Theatre LG29,

Abstract Cardiovascular mechanisms exhibit both linear and nonlinear interactions. Linear approximation of these interactions cannot capture the nonlinear dynamics rendering results incomplete, while nonlinear methods generally do not distinguish between linear and nonlinear relationships. In this study, we investigated whether nonlinear analysis (transfer entropy analysis) of a linear model’s residuals can provide this distinction. The linear dynamics in the data were captured using a linear autoregressive model. Transfer entropy analysis was applied to the model residuals to investigate whether they…

Qing Sun – Stability Analysis and Design of Moving Horizon Estimator for Markov Jump Systems

October 27, 2016 @ 4:00 pm - 5:00 pm

Abstract An moving horizon algorithm is presented with mode detection for state estimation problem of the discrete-time Markov jump systems in the presence of Guassian noises. This new state estimation scheme is a combination of the maximum-likelihood algorithm and the moving horizon approach. The former is for obtaining optimal estimate in maximum a posterior sense of mode jumping sequence within a moving fixed-size horizon, and the latter is an optimal filter. Based on these two techniques, a mode detection-moving horizon…

A. S. Nazmul Huda – Multilevel Monte Carlo Method for Power Distribution Systems Reliability Assessment

November 3, 2016 @ 4:00 pm - 5:00 pm
Lower Napier Theatre LG29,

Abstract The seminar presents an application of new multilevel Monte Carlo (MLMC) simulation approach to assess the reliability of power distribution systems. Monte Carlo simulation (MCS) is generally employed for distribution systems reliability analysis. MCS may be computationally expensive to obtain a high accuracy, where a large number of samples are necessary. The purpose of using proposed MLMC is to improve the computational efficiency of MCS. The MLMC method achieves less computational cost by approximating the solution of SDE with…

Prof Jinho Choi – Wireless Security in Smart Grid

November 10, 2016 @ 4:00 pm - 5:00 pm
S111, Engineering South
Adelaide, South Australia Australia
+ Google Map

Abstract Smart grid can have a number of advantages over conventional power grid by using information and communication technology. For smart grid, advanced metering infrastructure (AMI) plays a crucial role in efficiently utilizing energy. To provide flexibility and low-cost deployment, wireless communications for smart meters are considered in AMI. However, unfortunately, wireless communications are prone to various security attacks including eavesdropping. In this talk, we present an approach to provide security in wireless communications for smart grid using physical layer…

Hang Yin – An Application of Probabilistic Collocation Method in Wind Farms Modelling and Power System Simulation

November 24, 2016 @ 4:00 pm - 5:00 pm
S111, Engineering South
Adelaide, South Australia Australia
+ Google Map

Abstract The Probabilistic Collocation Method (PCM) is introduced to solve a stochastic model representing wind farms in South Australia (SA). The model is based upon historical acquisition of wind source data, and considering the spatial correlation of wind speeds at neighboring wind farms. This correlation is used to reduce the number of uncertain parameters of the model, and then reducing the cost of PCM computation. In addition, fuzzy logic optimization is applied to PCM to improve the accuracy of the…

Witold Pedrycz – Information Granularity in Intelligent Data Analysis and Decision-Making Processes

January 18 @ 4:00 pm - 5:00 pm
Ingkarni Wardli 5.57,

Abstract Information granules play a pivotal role in acquiring, representing, processing, and communicating knowledge at a suitable level of abstraction. Designing information granules is paramount to all pursuits of Granular Computing. This presentation offers a comprehensive and systematically structured overview of methodologies and algorithms of designing information granules along with a suite of representative applications in data analysis and decision-making. The taxonomy embraces two main categories of data-driven and knowledge-oriented approaches. We introduce and discuss a principle of justifiable granularity,…

Adj. Assoc. Professor Bernd Fischer – Breaking the Diffraction Limit in the THz frequency range

February 16 @ 4:00 pm - 5:00 pm

Abstract In the past two decades, terahertz time domain spectroscopy (THz-TDS) has proven to be a very versatile method for the investigation of molecular systems and for applications contact-free inspection and quality control.  As a consequence, several commercial suppliers offer various systems for a steadily growing market. However, while the method seems more or less established for the above mentioned applications, the hopes and expectations in the technique in particular for medical applications have not been fulfilled. This is mainly…

IEEE Distinguish Microwave Lecturer – Prof. Naoki Shinohara – Current Research and Development of Wireless Power Transfer via Radio Waves and the Application

February 27 @ 4:00 pm - 5:00 pm
Napier G04,

Abstract Theory, technologies, applications, and current R&D status of the wireless power transfer (WPT) will be presented. The talk will cover both the far-field WPT via radio waves, especially beam-type and ubiquitous-type WPT, and energy harvesting from broadcasting waves. The research of the WPT was started from the far-field WPT via radio waves, in particular the microwaves in 1960s. In recent years this became a hot topic again due to the rapid growth of wireless devices. Theory and technologies of…
