Medical Body Sensor Networks: Challenges, Opportunities, and Current Efforts. 

A light lunch will be available from 1.15pm in the same room for those attending the seminar. 

Abstract
Body sensor networks (BSNs) are an emerging technology that have the potential to impact the healthcare industry. They enable mobile monitoring scenarios to provide otherwise-unobtainable information about patients to clinicians to aid in research as well as clinical practice. These new ways of instrumenting and monitoring humans in their natural environments come with many challenges. Body sensor networks are complex cyber-physical systems of physically distributed nodes around the body that must coordinate to provide relevant information. They are mobile and typically small, hence limited to fewer resources, but must operate in a complex, highly dynamic and unpredictable environment which requires computational intelligence. This talk will highlight some of the applications of body sensor networks, breakthroughs made in technologies that are overcoming some of the challenges, and some open questions. In addition, I will briefly touch on my current efforts to aid in translation to market of these systems, where I am developing model-driven approaches to enable reasoning about and analyzing these systems with respect to their patient safety implications, an issue that is important to regulators who must certify these systems for use on the market and manufacturers who must seek regulatory approval.

EDF Energy Lecture -  The Fukushima Nuclear Accident & the UK Response

Synopsis: After the nuclear accident at Fukushima Dai-ichi in March 2011, following the Japanese earthquake and tsunami, the global nuclear industry challenged nuclear safety at power stations around the world.

EDF Energy as the largest UK Nuclear operator set up a programme of work to review the safety of their stations and although it was concluded that there are no fundamental weaknesses in design and resilience for 'within design basis' events, EDF Energy is committed to delivering a comprehensive work programme to further enhance resilience and response to extreme natural events. This presentation will look at what happened at Fukushima and how EDF Energy are responding.

'THz Frequency Selective Surface Filters for Earth Observation Remote Sensing Instruments'.

Abstract: In the past decade Earth observation instrument technology has largely been driven by the need to provide spectroscopic characterisation of the Earth’s atmosphere for studies which will provide new insights into phenomena including atmospheric composition, ozone depletion and climate change. What these missions have in common is that they require state-of-the-art hardware to achieve the high receiver sensitivity necessary to detect weak molecular emissions at mm and sub mm wavelengths. To satisfy satellite payload constraints on cost, mass and energy consumption, passive remote sensing radiometers traditionally employ a single mechanically scanned aperture antenna to collect radiation over a wide frequency range. The signals are spatially and spectrally separated within the heterodyne receiver by Frequency Selective Surfaces (FSS). The key technology challenge is to ensure that the devices simultaneously exhibit very low signal band insertion loss and meet the conflicting requirement for high isolation between adjacent frequency bands. The purpose of this talk is to present an overview of a multidisciplinary research project at Queen’s University Belfast which has exploited state of the art developments in silicon micromachining technology to create a new class of substrateless FSS which exhibit enhanced performance and functionality. This type of structure has very high mechanical strength and rigidly properties which satisfy the requirements for space deployment. Finally the results of recent work to create electronically tunable mm wave FSS and reflectarray structures based on Liquid Crystals will also be presented.

Title: Cortical Neurodynamics Explored: Challenges in Neural Signal Processing

Abstract: Brain signal dynamics can be explored through a variety of methods, this talk introduces analysis techniques applied to the electromagnetic signals recorded from the brain – mainly through the electroencephalogram (EEG) , and will highlight the information that these signals can yield. From the diagnosis of epilepsy, to the prediction of epileptic seizures, scalp recordings of the electrical activity of the brain can be used to tell much about when and where activity of interest is happening within the brain. Of the many techniques in the literature, Independent Component Analysis (ICA) is generally used when it is required to separate measured multi-channel biomedical signals into their constituent underlying components. Fundamentally ICA in biomedicine involves the extraction and separation of statistically independent sources underlying multiple measurements of biomedical signals. In this talk I will overview the different capabilities of extensions to the basic ICA premise using techniques based on space, time, frequency and joint space/time-frequency decomposition of brain signal recordings. In summary, this presentation will talk about the issues surrounding the analysis of these complex EEG signals and will touch on where brain signal analysis may be going – especially in brain-computer interfacing.

'Towards a New Science of Big Data Analytics,Based on the Geometry and the Topology of Complex, Hierarchic Systems' (pdf 780 KB) .

Abstract: My work is concerned with pattern recognition, knowledge discovery, computer learning and statistics.   I address how geometry and topology can uncover and empower the semantics of data.   In addition to the semantics of data that can be explored using Correspondence Analysis and related multivariate data analyses, hierarchy is a fundamental concept in this work.    I address not only low dimensional projection for display purposes, but carry out search and pattern recognition, whenever useful, in very high dimensional spaces.   High dimensional spaces present very different characteristics from low dimensions,  I have shown that in a particular sense very high dimensional space becomes, as dimensionality increases, hierarchical.   I have also shown how in hierarchy, and hence in an ultrametric topological mapping of information space, we track change or anomaly or rupture.

The Jennifer Aniston neuron.

We can easily recognize a person or an object in a fraction of a second even when seen under strikingly different conditions. How neurons are capable of creating such an invariant representation has been a hot topic of debate in Neuroscience. In epileptic patients candidates to surgery we analyzed the responses of neurons in the human medial temporal lobe to picture presentations. Several technical improvements led to the finding of 'abstract' neurons that fired selectively to different pictures of familiar individuals (e.g. Jennifer Aniston) and even to their written names. If time permits, I will also show that from the firing of these neurons it is possible to predict what the subjects are seeing and that subjects can voluntarily modify the neurons' firing to 'project thoughts'. Finally, I will discuss the possible function of these neurons.

Bio for Professor Rodrigo Quian Quiroga
One of the major scientific challenges of our days is to understand how information is represented by neurons in the brain. Although there has been spectacular progress in the last decades, we are still far to comprehend, for example, how visual inputs are processed to create conscious percepts and how these percepts can create new memories.

To understand these principles of brain function we perform single cell recordings in epileptic patients -implanted with intracranial electrodes for clinical reasons-, electroencephalographic and eye-tracker recordings and we use a sophisticated robot arm to study potential clinical (Neuroprosthetic) applications. Since complex behaviour is encoded by the activity of large populations of neurons, we also work on the development of advanced methods to extract useful information from these data.

Rodrigo is basically puzzled by how the brain works. In particular he is interested is principles of Neural Coding, visual perception, memory, visuo-motor transformations, single-trial evoked potentials, synchronization and the development of methods for the analysis of neurophysiology data

'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.

Intelligent Optimisation

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.

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.
