'National Instruments RF & Microwave Discussion'
Abstract:As an organisation, National Instruments have been heavily investing RF & Microwave Technology, the result of which provides a novel approach to RF instrumentation. This modular, software-defined approach is helping scientists and engineers continue to innovate in the midst of the ever-changing demands of the wireless industry. Industry leading I/O from DC up to 26.5GHz can be configured in phase coherent MIMO configurations, up to 16x16, and FPGAs can be used for real time signal processing; perfect for a bespoke measurement system or an off the shelf radio prototyping platform. Couple this modular hardware, with flexible software that gives industry leading measurement speed for current and emerging standards such as LTE, WLAN and WiMAX, to provide highly optimised solutions that reduce the cost of test whether for characterisation, design validation or production.

Abstract:Intelligent Optimisation Many real-world engineering problems require the manipulation of a number of system variables in order to optimise a given quality parameter such as the reliability or accuracy of a process, or the cost or performance of a product. Optimisation will become even more important as resources diminish. The Bees Algorithm models the foraging behaviour of a swarm of honeybees in order to solve complex optimisation problems. The algorithm performs a combination of exploitative neighbourhood search and random explorative search. In this presentation, we will review different formulations of the Bees Algorithm together with other swarm-based optimisation algorithms and compare the effectiveness of the Bees Algorithm to that of three other biologically inspired search methods. We will explain the search mechanisms of the Bees Algorithm and the three control methods, and highlight their differences, strengths, and weaknesses.
Biography:Duc Pham is Chance Professor of Engineering and Head of the School of Mechanical Engineering. His research interests include intelligent systems and manufacturing.

Professor Newell, University of Dundee
Abstract: Computer systems appear to be designed mainly for young to middle-aged, computer literate people with high cognitive skills. However, an increasingly ageing population and disability legislation means that the ability to design for “extra-ordinary” - older and disabled - users should be a critical part of the toolkit of HCI researchers and C & IT designers.
Focussing on the needs and wants and abilities of older and disabled people, not only produce products and services for those users, but also can produce systems which are more easily usable by young non-disabled people.
This process will be illustrated by examples drawn from over 25 years research and development in this area at Dundee University. These include communication systems for non-speaking people, software support for those with dyslexia, smart house technology, and computer systems to support people with dementia.
Biography: Alan Newell, who graduated from Birmingham University’s Electrical Engineering Department in 1962 and 1965, is now an Emeritus Professor at Dundee University’s School of Computing.
The School contains one of the largest academic groups in the world researching into computer and communication systems for older and disabled people. He has published widely in this field, including his recent book: “Design and the Digital Divide: insights from 40 years in Computer Support for Older and Disabled People” (Morgan & Claypool 2011). His current interest is the use of professional theatre to raise awareness and facilitate discussion on these issues.
He was appointed a Member of the Order of the British Empire in 2000 for contributions to computer-based systems for people with disabilities. In 2011 was presented with the (US) Association for Computing Machinery SIGCHI Social Impact Award, and in 2012 elected a member of the ACM SIGCHI Academy.
A former Deputy Principal of the University, Alan is a Fellow of the Royal Society of Edinburgh, the Association for Computing Machinery and the British Computer Society, and an Honorary Fellow of the Royal College of Speech and Language Therapists.

Perception of Humanoid Agents and Pedestrian Crowds in Simulated Virtual Environments
Abstract: This presentation describes research involving the perception of believable behaviour in humanoid agents and crowds situated in simulated virtual environments. Videos of high-density pedestrian scenes are inspected and annotated in order to synthesise virtual scenes of pedestrian configurations. These configurations are subsequently altered algorithmically at the level of the individual, group and crowd, in order to probe user perceptions of naturalness. The presentation will highlight the importance of the role of context in which behaviour takes place to its perception and also raise the issue of cases where differentiations may be made between the perception of realistic versus believable behaviour.

Discrete Transformation Electromagnetics and its Applications in Antenna Design’.
Abstract:Current designs of electromagnetic cloaks are largely based on the use of metamaterials and a technique so-called "transformation optics/electromagnetics". Free space cloaks require extreme materials which are difficult to implement in practice, however, the theory of "transformation optics/electromagnetics" offers a useful design tool for antenna engineers in developing novel antennas. In this talk, the theorem of discrete transformation electromagnetics is introduced and later applied to the design of flat lens and reduction of antenna mutual coupling.
Biography of Yang Hao: Yang Hao received the Ph.D. degree from the Centre for Communications Research (CCR) at the University of Bristol, U.K. in 1998. From 1998 to 2000, he was a postdoc research fellow at the School of Electrical and Electronic Engineering, University of Birmingham, U.K. In May 2000, he joined the Antenna Engineering Group, Queen Mary College, University of London, London, U.K. first as a lecturer and was promoted to Reader in 2005 and to Professor in 2007.

Applications of Resonant Microwave Sensors
Abstract:The first part of this talk concerns the use of resonant microwave sensors for the determination of fundamental electronic properties of materials. Two examples will be discussed, namely the chatacterisation of carbon nanotubes, and new types of transparent conductors. The same types of devices also have many potential applications, and this forms the basis of the second part of the talk. Two devices will be discussed in detail. The first is in the area of microfluidics, where very accurate dielectric measurements of small amounts of fluid are possible. The second is in the area of medical devices, where a new type of non-invasive blood glucose monitor has been developed.
