Title: Plant Electrophysiology for Monitoring Environmental Parameters Abstract: Plants produce electrical signals, when subjected to various environmental stimuli. These electrical signals in essence represent changes in underlying physiological processes influenced by the external stimuli. Thus, analysing such plant electrical signals may uncover possible signatures of the external stimuli embedded within the signal. The stimuli may vary from different light conditions, burning, cutting, wounding, gas or liquid etc. This opens up the possibility to use such analysis techniques to turn a green plant into a multiple-stimuli sensing biological sensor device. If such an association between the external stimuli and the resulting plant electrical signal could be made, then it may serve the purpose of holistic monitoring of environmental constituents at a much cheaper cost (because of abundance of plants) thereby eliminating the need to install multiple individual sensors to monitor the same external stimuli. In this work, we attempt to explore the possibility of classifying three external stimuli - Sodium Chloride (NaCl), Sulphuric Acid (H2SO4) and Ozone (O3), from the electrical signal response of plants as the first step towards that goal. Bio: Dr. Shre Kumar Chatterjee passed his B.Eng (Electronics and Communications) from Visvesvaraya Technological University, Belgaum, India in 2004. He worked as a trainee consultant and soon headed a newly formed division (which included training students in Microprocessor/Microcontroller programming etc., and liasing with corporates and educational organizations for recruitment of engineering graduates). Thereafter he pursued an MSc in Nanotechnology at University of Southampton during 2005-06. After the successful completion of his MSc, he was involved in several high profile projects in the industry in the microfabrication domain, specializing in Organic Thin Film Transistors (for active matrix flexible and rollable displays). In 2012, he left the industry to pursue a full time PhD under Dr Koushik Maharatna and Dr Srinandan Dasmahapatra to pursue his interests in Machine Learning and Signal Processing. He has worked on Image Processing, EEG Signal analysis and currently working on a short term contract under Dr Geoff Merrett in project PRiME.

ABSTRACT: The development of machine vision solutions in silicon presents significant challenges in terms of architecture and implementation. The high speed and bandwidth requirements alone require the systems to achieve the highest performance levels. In addition, enabling re-use for derivative solutions whilst committing to an aggressive time-to-market in a fast-moving landscape pushes the challenges beyond technical implementation considerations. Everything from architecture to code structure to software hooks needs to align seamlessly. In this talk Sondrel will share some examples and experiences of developing SoC solutions for machine vision applications.

“I’m delighted to be appointed Entrepreneur in Residence by the Royal Society,” she says. “During my time as a mentor at Future Worlds, I’ve greatly enjoyed getting to know the University of Southampton community and meeting entrepreneurially-minded staff and students doing world-changing things. The University has a brilliant culture of enterprise and I’m looking forward to expanding upon my work with Future Worlds and ECS to further promote and support entrepreneurship.”

Last summer, Virginia joined a panel of experts at the University of Southampton as they discussed the barriers to women’s participation in the worlds of engineering and enterprise.

Ben Clark, Future Worlds Director, says: “It’s fantastic news that Virginia has been recognised by the Royal Society with this award. She has been an invaluable member of the Future Worlds community through bringing her expertise to many of the startups and spinouts in our network. I’m thrilled that the Royal Society is enabling the furthering of this impact and look forward to more opportunities to work with Virginia along with the School of Electronics and Computer Science to further accelerate the commercial potential within ECS and the Future Worlds network.”

BIOMEDICAL SEMINAR - with Prof Guillaume Charras from the London Centre for Nanotechnology, UK
 
 
Title
 
Relaxation and blistering in epithelial cell monolayers     
 
 
 
Abstract
Epithelia are planar tissues, separating the internal environment from the external environment in many organs. Epithelia are subjected to mechanical perturbations that vary greatly in magnitude and timescale during development, normal physiological function and regeneration. The speaker will present two recent studies that examine the behaviour of monolayers over short or long time-scales.

The Centre for Internet of Things and Pervasive Systems is organising a seminar on "Hardware-Based Security Solutions for the Internet of Things" from Dr Basel Halak. The event is open to anyone from across the University to attend. The Internet of Things (IoT) is expected to generate tremendous economic benefit; this promise is undermined by major security threats. First of all the vast majority of these devices are expected to communicate wirelessly, and will be connected to the Internet, which makes them especially susceptible to confidentiality threats from attackers snooping for messages contents. Second, most IoT devices are expected to be deployed in remote locations with little or no protection; therefore they can be vulnerable to both invasive and side channel attacks, malicious adversaries can potentially gain access to a device and apply well know power or timing analyses to extract sensitive data that might be stored on the IoT node, such as encryption keys, digital identifiers, and recorded measurements. Furthermore, with ubiquitous systems, it can no longer be assumed that the attacker is remote. Indeed, the attack could even come from within the system itself, from rogue embedded hardware (e.g. Trojans). A large proportion of IoT devices operate in an energy-constrained environment with very limited computing resources, this makes the use of typical defence mechanisms such as classic cryptography algorithms prohibitively expensive. The challenges for building secure IoT are threefold: • How to develop hardware which is inherently resilient to physical attacks • How to implement complex security protocols with very limited resources • How to detect/diagnose anomalous behaviour of an IoT device This talk addresses the above three questions, as follows: 1) The first part of this talk addresses the first question, it presents two novel approaches for enhancing the security and reliability of physically unclonable functions, one of the enabling technologies designing Tamper resistant hardware. The first technique propose a physically unclonable function using instruction cache, typically found in all embedded processors. The design is optimised to improve resilience to ageing effects. The second approach aim to enhance the security of physically unclonable functions against modelling attacks by combining these with low cryptographic primitives such as permutation and substitution. The proposed techniques makes its affordable, secure and reliable to use physically unclonable technology in resources constrained systems. 2) The second part of this talk addressees the second question, it presents a new authentication protocol based on PUF technology, Then power consumption and memory utilization of the proposed protocol were estimated and compared with the existing solutions, namely: DTLS (datagram transport layer security) handshake protocol and UDP (user datagram protocol). Our results indicate that the proposed PUF based authentication saves up to 45% power and uses 12% less memory compared to DTLS handshake authentication. 3) The third part of this talk addresses the final question, it presents a new detection technique for malicious/abnormal behaviour of embedded using data from Hardware Performance Counters (HPCs). Finally the talk concludes with a summary of outstanding challenges.

The Centre for Internet of Things and Pervasive Systems is organising a seminar titled "Energy Driven Design of Self-Powered IoT Devices: Applications in Cycling Performance Monitoring" from Samuel Wong, a fourth year undergraduate student in ECS. The event is open to anyone from across the University to attend. The Energy Driven Paradigm is an approach to designing energy harvesting devices where explicit consideration is given to the energy supply and demand characteristics of the application at the very beginning of the development cycle. Instead of designing an IoT device and then optimizing for battery life, or using energy harvesting to extend battery life, what if we start from the harvester and design a system tailored to the harvester. This paradigm shift introduces some interesting challenges, for example the need to have sustained computation spanning intermittent power outages and to have energy aware devices which can respond dynamically to energy scarcity or abundance. Two IoT devices with dramatically different energy harvester characteristics are presented as a case study into the energy driven design process, which were researched through my undergraduate PIII project and summer research internship in ECS. The first device is a wind and inclination meter powered from a tiny wind turbine which gives a low but steady AC power, whereas the second is speed and distance meter powered from periodic pulses of energy. Both devices have wireless connectivity and are battery-less.

The Centre for Internet of Things and Pervasive Systems is organising a seminar on "Automatic Aggregation of IoT Sensor Data for Health and Safety Monitoring" from Dr Paolo Pareti. The event is open to anyone from across the University to attend. Effective use of IoT sensor data often requires abstracting low-level information from multiple sensors into more high-level and actionable knowledge. In this talk I will present an automatic approach for the aggregation of sensor data and its evaluation. We will present the results of an experiment where human participants are presented with a simulation and asked to decide which emergency response action to take (if any). This study investigates the effectiveness of automatically-generated sensor summaries to support human decision making. We consider sensor summaries at different levels of granularity, and the the usefulness of modifying the granularity of these summaries on demand.
