AI for Robust Compression
IDCOM, University of Edinburgh, Edinburgh Institute of Sensors, Signals and Systems, Heriot-Watt University, Edinburgh
Image and video compression are essential for the efficient transmission of critical information in civilian and military contexts. The compression of information, however, renders it more vulnerable to interference, which can easily occur when the transmission occurs wirelessly (e.g., jamming/electronic attack). It is therefore of critical importance to develop image/video codecs that achieve high compression ratios and, at the same time, are resilient to interference or attacks. Standard codecs such as JPEG, H.264 and HEVC do not achieve these goals: while they offer respectable rate-distortion performance, none of them is resilient without significant adaptation.
This PhD position is part of the UDRC Phase III project http://udrc.eng.ed.ac.uk/ and will conducted in collaboration with Heriot-Watt University and with MBDA. It aims to investigate state of-the-art methods in machine learning and signal processing, such as deep learning, reinforcement learning, sparse modelling/inverse problems, and super-resolution, to develop a resilient compression codec. Encompassing an encoder and a decoder, this codec should recover high quality imagery across a range of data rates after wireless transmission, and guarantee optimal performance in extreme environments. A codec that meets these requirements not only has the potential to become a baseline solution for both commercial and mission critical applications, but also to be deployed in civilian environments that require resilience to attacks, for example, IoT and 5G.
This project will be supervised by Dr. Sotirios Tsaftaris, from the University of Edinburgh, and Dr. Joao Mota, from Heriot-Watt University.
The student will work on the University Defence Research Collaboration (UDRC) http://www.mod-udrc.org/ which is a leading research partnership for signal processing for defence and develops new techniques to better transform data across many domains into actionable information, and meet the requirements for improved situational awareness, information superiority, and autonomy. This collaboration, sponsored by Dstl and the EPSRC, is academia-led and has commenced its third phase of research focusing on "Signal Processing in the Information Age". The Consortium is made up of the University of Edinburgh, Heriot-Watt University, Queen's University Belfast and University of Strathclyde and there are currently PhD opportunities available across the four universities to work on diverse topics in signal processing, as part of a collaborative team. The work will involve strong links with industry and the UK defence sector. The PhD student will be expected to work closely with other research team members and to attend regular meetings to present project updates to the sponsors and partners of this project.

PhD in Algorithmic Approximate Computing
The aim of this PhD project is to develop techniques for performing approximate computation in energy-constrained environments. Although battery lifetime has increased significantly over the last years, the most sophisticated data processing algorithms require so much computation that they cannot be deployed in operations using battery-powered drones or sensor networks. Such massive computation would indeed compromise the longevity of the operation. A solution is then to approximate the algorithms by decreasing the amount of computation, which can be done at the algorithmic level (e.g., by the selection of a more efficient optimization algorithm), all the way down to the hardware level (e.g., by reducing voltage).
This project will focus on the approximation aspects at the higher-levels, including the consideration of approximation at the problem formulation, the design of resilient optimization algorithms, and the development of approximate linear algebra. The goal is not only to design approximation algorithms, but also to analyze how approximations introduce errors and how these, in turn, affect the algorithm's performance and power savings. The student will look at two classes of algorithms for imaging tasks, such as classification, reconstruction, or super-resolution. One class of algorithms is based on convex optimization principles, for which there exist comprehensive performance analyses. The other class is based on nonconvex optimization, including algorithms used to train/update neural networks, for which performance characterizations are quite limited.
This project will be supervised by Dr. Joao Mota, Prof. Mathini Sellathurai, and Prof. Andrew Wallace, and will take place at Heriot-Watt University, Edinburgh.
The student will work on the University Defence Research Collaboration (UDRC) (www.mod-udrc.org), which is a leading research partnership for signal processing for defence and develops new techniques to better transform data across many domains into actionable information, and meet the requirements for improved situational awareness, information superiority, and autonomy. This collaboration, sponsored by Dstl and the EPSRC, is academia-led and has commenced its third phase of research focusing on "Signal Processing in the Information Age".

Candidates should have completed, or expect to complete, an MSc degree in Electrical Engineering, Mathematics, Computer Science, or similar. A strong mathematical background is essential and knowledge of optimisation algorithms, linear algebra, algorithm analysis, or machine learning is a big plus. Candidates should have an autonomous and proactive working style, and good communication skills.
The studentship is available for 3 years, starting from September/October 2019. There will be an annual stipend of around £15k, and no nationality restrictions.

Scalable methods for robust uncertainty quantification
Supervision team: Y. Altmann, Y. Wiaux, S. McLaughlin
Host institution: Heriot-Watt University – School of Engineering and Physical Sciences
This PhD project will investigate novel statistical methods combining the Bayesian formalism with high-dimensional optimization tools to infer parameters and associated uncertainty in large-scale (imaging) problems.
Future defence applications will involve challenges such as: the imaging, monitoring and analysis of underwater terrain and assets from heterogenous data: e.g. sonar and underwater Lidar; or the quantification of radioactive sources or pollutants from event-data, time-of-flight (ToF) data and spectral measurements. These are examples of severely ill-posed inverse problems with potentially multi-modal data where advanced signal models coupled with quantification of uncertainty will be instrumental in aiding signal and image recovery. This project will focus on solving such inverse problems, enhancing optimisation with post-optimisation confidence estimates. Among the different applications mentioned above, the proposed methodologies will be applied in particular to imaging and sensing applications in complex environments.
Convex and nonconvex optimisation tools offer the potential to enable fast scalable robust Bayesian inference in high dimensions. Proximal calculus algorithms rooted in optimisation as well as random data selection approaches and approximate Bayesian computation (ABC) to accelerate Monte Carlo sampling will be the focus of this work. Using proximal optimisation algorithms and ABC to explore the confidence region defined by Bayesian models around initial point estimates offers a route to scalable uncertainty quantification for large scale inverse problems but work is required to achieve this and to expand it to deal with multi-modal data. The issues of parallelisation and distribution functionalities, as well as the convergence properties of these proximal methods must also be addressed to enable scalable solutions to be developed.
The University Defence Research Collaboration are pleased to invite applications for PhD studentships to work as part of a leading team of experts in signal processing. The project will be hosted by Heriot-Watt University and the student will work on the University Defence Research Collaboration (UDRC). The UDRC is a leading research partnership for signal processing for defence and develops new techniques to better transform data across many domains into actionable information, and meet the requirements for improved situational awareness, information superiority, and autonomy. This collaboration, sponsored by Dstl and the EPSRC, is academia-led and has commenced its third phase of research focusing on "Signal Processing in the Information Age".

2D and 3D Computational Imaging Through Turbulence
The main objectives of this computational PhD project are to develop new and ground-breaking methods for fast and robust 3D imaging and sensing. This ambitious project will concentrate on real-time solutions for analysis of long-range 3D scenes (object detection and 3D reconstruction) in the presence of scattering media and atmospheric turbulence.
Within the School of Engineering at Heriot-Watt University (HWU), the signal/image processing and optics research groups (http://www.single-photon.com) are working together to push the frontiers of 3D imaging. In particular, the high sensitivity of photodetectors allows for the use of low-power laser sources (ranging from the visible through infrared frequencies), a key element for defence applications and resource management in embedded systems. Similarly, gated-cameras, which are less expensive and potentially allowing faster acquisitions can also be used.
Among the wide variety of 3D imaging applications, long-range imaging in the photon-limited regime is of prime interest for Leonardo. Long distances (several kilometres) exacerbate the nuisance effects of light propagating through scattering media (e.g., fog) and atmospheric turbulence (e.g., wind) which in turn produce signal distortion and additional sources of uncertainty that require new algorithms to be developed. While the most recent reconstruction methods provide very good reconstructions under mild turbulence and scattering, they still require prohibitive computing times. Preliminary results (publications under review) have demonstrated the benefits of massively parallelisable algorithms allowing unprecedented frame rates while ensuring state-of-the-art estimation performance and this PhD project will continue in this direction of research. While scalable/parallelisable algorithmic structures will be adopted for fast information extraction, they will be embedded within a statistical/Bayesian framework, allowing rigorous uncertainty management tools. This is particularly relevant to account for the uncertainty and variability of data acquired in the presence of scattering media (fog/aerosols) and atmospheric turbulence.
The PhD student will be primarily based on the Edinburgh campus of HWU and will join the ISSS institute and the research groups of Dr Y. Altmann and Prof. S. McLaughlin. This project will be conducted in collaboration with the HWU IPAQS institute (Prof. G. Buller) and Leonardo.
Requirements for this project
Excellent background in statistics, Bayesian inference and computational imaging and data science
Excellent programming skills (Matlab, C++), parallel programming desired
Experience with optical physics desired
The PhD project, funded in part by Leonardo (https://www.uk.leonardocompany.com) and CENSIS (https://censis.org.uk) is available for 3.5 years preferably for UK and EU nationals. This funding includes stipends of ~£14.5k per year and full tuition fees covered for 3.5 years.

Electromagnetic Sensors for Wearable Healthcare Applications
Wearable electronics technology for healthcare management, personal safety, and consumer products enhancement has the potential to transform our everyday life and improve the quality of living of healthcare patients and athletes. Non-invasive healthcare monitoring of body signal bio-parameters – such as movements, respiration, and temperature – without physical intervention or interaction with the patient is particularly of interest in this project. To date, the widespread adoption of many body wearables is limited due to intrinsic limitations mainly related to the flexible/rigid interface: complex wiring, mechanical/electrical reliability, presence of rigid and bulky batteries and charging circuits, washability. Seamless integration is key for user convenience that will ultimately lead to adoption of the technology in everyday applications.
This PhD research project envisages developing a wireless body sensor reader that can detect and estimate human body signals through a passive radio-frequency interrogation process and will be integrated with a sensing antenna. It is expected that this PhD research project will change the conventional approach to wearable healthcare electronics, ultimately leading to novel RF circuit architectures that take advantage of modern System-on-a-Package and System-on-a-Chip technology developments, and it may be a key enabler in lowering healthcare costs, particularly for the elderly.

Downhole Wireless RF Communications for Deployment in Oil and Gas Wells
There is an industry desire to create and extend the usage of RF wireless technologies to develop future digital-based oil fields. In particular, this PhD project will assess current evolving aspects of wireless technology to be adapted for providing sub-surface monitoring of Oil and Gas wells. Currently most well measurement communications systems employ permanently installed electrical cables or acoustic technologies.
The intention of this project is to assess and model the physical wellbore architecture and EM environment for the application of wireless RF communications in shallow sub-surface well environments; initially identifying the potential transmission schemes and then developing a wireless RF communications system (early prototype) to prove and validate the novel concept. The prototype, once developed, is patentable and will involve the development of new antennas and RF components as well as the system modeling, design, and implementation. At least two IEEE publications are expected from this research as well as conference publications and travel. This engineering research also has the opportunity to deliver low cost well performance for monitoring well head operational efficacy and crude throughout. Applications are expected for the Global Oil & Gas market sectors. Moreover, this proposed wireless well communications modem system can benefit the Global Oil and Gas industry by reducing the high cost of well interventions ($1 million / well) and can provide a key enabler for deploying low cost well measurement technology in wells and further allow for the introduction of new wireless RF sensor technologies.
In addition to this cost savings, there are significant benefits to production optimization by measuring more wells on a continuous basis. It is expected that this PhD research project, to develop the first RF wireless modem system for wells in the Global Oil and Gas Industry, will change the conventional approach to well measurements and monitoring. This can deliver a cost effective technology solution to enable the monitoring of more wells on a continuous basis. Ultimately this RF communications technology implementation can lead to the lowering of the number of routine well interventions, and, it may be a key enabler to lowering crude costs. In addition, the proposed wireless RF sensor communication system may foster the permanent monitoring of Oil and Gas wells with enhanced efficacy.

PhD in Signal Processing Techniques For Biological Imaging
The aim of this PhD project is to develop new imaging techniques for biological microscopy. One of its components is the design of signal processing and machine learning algorithms that super-resolve cell images using as an aid images obtained in a different range of the spectrum. Specifically, some microscopes are equipped with two cameras, which may capture different ranges of the spectrum: one camera has high spatial resolution but low temporal resolution, while the other has low spatial resolution but high temporal resolution. Our goal is to use post-acquisition processing to boost the spatial/temporal resolution of both cameras.
Another component of the project concerns single-photon avalanche photodiode (SPAD) array cameras, which work by taking a large number of measurement images from a given biological setting. Each measurement image, however, is extremely sparse, and therefore the biological setting can be reconstructed only if we use a large quantity of measurements. A recurrent problem in practice is that there are no estimates for how many measurements are required for successful reconstruction. One of the goals of this project is precisely to design algorithms that perform reconstruction from SPAD measurements and to establish estimates on the number of measurements that they require.
This project requires a strong mathematical background, but no prior experience in biological imaging is expected. Candidates should have completed, or expect to complete, an MSc degree in Electrical Engineering, Mathematics, Computer Science, or similar. Knowledge of optimization algorithms, compressed sensing, and machine learning is a plus. Candidates should have an autonomous and proactive working style, and good communication skills.
Due to funding restrictions, only UK or EU students are eligible for this studentship. The studentship is available for 3 years, with a tax-free stipend of £14,553 p.a., and start date February 2018.
To apply, please send a CV, a cover letter, and contact details of at least two referees to Dr Joao Mota and to Dr Colin Rickman quoting "PhD in Signal Processing Techniques For Biological Imaging" in the email subject. Informal queries can also be addressed to Dr Mota.
PhD Project in the Area of Sensor Manufacture - Novel Lactate/pH Sensor for Monitoring of Baby Delivery
Project Description: Currently 300,000 pregnant women a year in the UK have their babies monitored during labour using cardiotocography (CTG), as recommended by the NICE intrapartum care guideline. It is however recommended that fetal blood sampling, where a sample of blood is taken from the baby’s scalp, is used in conjunction with CTG monitoring to confirm the acid-base and lactate balance of the fetus. Unfortunately current methods of taking fetal blood samples are time-consuming, technically difficult, unreliable, and require the use of an expensive separate blood gas analyser. They also only give a snap-shot of the state of fetal wellbeing at the time of sampling and do not provide a continuous real-time assessment of fetal wellbeing. There is therefore an unmet clinical need for a device capable of providing accurate real-time assessment of fetal acid-base and lactate state though-out labour to inform timing of delivery and prevent brain injury.
We are looking for a creative and highly motivated student willing to work in the field of sensor manufacturing in collaboration with our colleagues from the University of Edinburgh and the Charity Tommy's. Studies in Chemistry, Physics, or Engineering (Electrical, Mechanical, Chemical, Materials, Biomedical or related), are desired. The student is expected to work effectively as a part of a team, both in the host institution and with the project partners. Good manufacturing and/or experimental skills are required.
The student is funded by the UK Engineering and Physical Sciences Research Council (EPSRC) under its Centre of Doctoral Training (CDT) programme. This particular CDT is run in collaboration with the University of Loughborough although the PhD position will be at Edinburgh (Heriot-Watt University and the University of Edinbugh). The project consists in the development of a novel lactate/pH sensor to monitor hypoxia during the delivery of babies. The PhD will be developed under the supervision of Prof. Marc Desmulliez (Engineer at Heriot-Watt University) and Dr Fiona Denison (Obstetrician at the University of Edinburgh/NHS Lothian). The Charity organisation, Tommy's, is sponsoring part of the PhD studentship. Heriot-Watt is Scotland's most international university, boasting the largest international student cohort, with five campuses in three countries. In a strategic partnership with the University of Edinburgh, EPS was ranked first in power ratings in General Engineering by the last Research Excellence Network assessment of UK research quality (REF2014).

Improving detection and estimation of birds’ collision risk with energy infrastructure
New tracking technologies have enabled researchers to unravel previously unknown animal movement strategies and migratory routes. The use of animal tracking devices that collect high temporal and spatial precision data, including altitude information has been increasing in recent years. Altitude data is necessary to estimate birds’ collision risk with offshore wind turbines, electricity cables or other energy infrastructure. This information is key and part of the decision-making process for proposed renewable developments. Areas with high collision risk should be avoided. This project has two components, first it will examine existing animal movement data, from devices that provide accurate elevation information and will examine bird collision risk with the energy infrastructure in Europe. This is important to identify areas with high collision risk that need mitigation actions. The second part of the project will focus on the development of new technology to determine when a bird actually collides. The devices will be tested during the PhD and the results of this project will open new avenues for identification of risk of collision, an issue that is increasing in importance worldwide.
Methodology: We will use data on the movement of migratory birds from a variety of projects freely available on Movebank. Movement characteristics (altitude, speed, direction, flight type and distance moved) will be used to determine locations of high collision risk. This project will also take advantage of existing high temporal and spatial resolution data from ~80 white storks and will use newly developed features to identify collision events. The student will be involved in the development of the new features. The collision risk with energy infrastructure will be determined using GIS approaches. The student will benefit from the expertise in data analyses and field techniques provided by the supervisory team and collaborating partners.
Deadline for applications: 16th January

Multiple Vehicles Maritime Autonomy for Oceanography
Monitoring oceanographic phenomena, be they physical, chemical or biological requires sample data, taken at the right place, time and frequency to detect, qualify and model them. Currently, this is typically done from ships, moored or drifting platforms with limited embedded intelligence and no ability to modify their trajectories to adapt their sampling strategy. Gliders and autonomous surface and underwater vehicles have recently been introduced and have the ability to perform 3 dimensional sampling whilst controlling their location precisely. However, they are currently using pre-planned missions and do not adapt to the sensors measurements. They also do not collaborate as a team to tackle a joint mission optimally. As these platforms mature and become a commodity, they have the potential to become a powerful and adaptable sensor network. What is required is the autonomy framework to manage the collaboration of the platforms together with the signal processing theory to understand the core issues of sparse sampling and reconstruction of the underlying phenomenon that network is observing, whilst taking into account the communications limitation of the underwater domain.
We propose to develop an autonomy architecture which tackles this generic problem (mobile sensor networks sampling theory) and apply it to one (or more) oceanographic problems. The target applications will involve the deployment of surface and underwater vehicles, equipped with relevant sensors (chemical, biological) whose collective target is to detect and monitor a specific scientific event by adapting the sampling strategy of the network to provide the best possible model of the observed event. We expect the architecture to be fully decentralized (each platforms takes its own decision based on information provided by its neighbours) and its adaptive behaviours to be driven by a mixture of offline modeling of the phenomenon and on-line adaptation to live sensor data. The system will be developed in collaboration with SeeByte ltd who have been involved in an SBRI project with NOC on Adaptive Autonomous Ocean Sampling Networks and are interested in sponsoring a Case studentship to continue this line of research. The validation would be performed in Heriot-Watt university on the Oceans Systems Lab assets in the initial stages but would eventually be tested on a real scientific issue using the MARS fleet.
Two scientific applications are envisaged to guide the development: open ocean deep convection and spring phytoplankton blooms. (1) Open ocean deep convection is a sporadic process where wintertime atmospheric cooling can make surface waters sufficiently dense to mix deeply (to 1000m or more). A field of convecting plumes is expected to be in a localized region of water---O(100km) across---surrounded by stratified water. The convective region is dotted with narrow mixing plumes (O(100m) across) where. A decentralized sampling system would enable near-real time mapping of the convective patch, where underwater vehicles could identify and characterize the boundary between convecting and stratified water, and higher resolution sampling within mixing plumes. (2) Phytoplankton blooms occur in the springtime, and are characterized by “patchy” areas of high fluorescence or production, interspersed with areas of relatively weak production. An adaptive sampling network could be applied to find, and then characterize, the spatial scales of phytoplankton production at high resolution. In both cases (1) and (2), the underwater sampling can be enhanced by surface measurements including meteorological data (in the case of convection) and irradiance (in the case of production).
The NEXUSS CDT provides state-of-the-art, highly experiential training in the application and development of cutting-edge Smart and Autonomous Observing Systems for the environmental sciences, alongside comprehensive personal and professional development. There will be extensive opportunities for students to expand their multi-disciplinary outlook through interactions with a wide network of academic, research and industrial / government / policy partners. The student will be registered at Heriot-Watt University, and will share time between Heriot-Watt and SeeByte.
The student will work in a multi-disciplinary team of engineers and scientists. The student will get exposure to the commercial world through its links and time spent at SeeByte ltd. He/She will also get a strong understanding of the embedded software required to smarten the current generation of autonomous systems and will be able to adapt them to new problems in the future.
