Our research has made an outstanding contribution to the ability of police forces to apprehend criminal suspects, particularly in cases of serious violent crime. EvoFIT is a facial composite system (software and procedures), designed to help victims and witnesses of crime to create a likeness of the perpetrator's face. It was conceived by Professor Peter Hancock in the mid-1990s and has been developed into an effective system that is in use by police forces across the UK and abroad. Forces using EvoFIT have actively collaborated with assessment of the system, and evidence from field trials clearly demonstrates the impact: a world-leading 25-60% of composites made with EvoFIT directly lead to an arrest, four times better than the best previous system used by police forces. Our novel methods for interviewing witnesses and for presentation of composites have enhanced the success of EvoFIT, and are now incorporated in competitor composite systems used by other police forces.
Our impact on the theory and practice of biometrics (identification of individuals through measurement/analysis of their physiological/behavioural characteristics) embraces contributions to technological development, to general systems-level principles and to public policy and professionalisation issues. Our research and consequent engagement across the stakeholder community has impacted on the technological development of practical biometrics through take-up by industry (e.g. InMezzo, one of the UK's leading secure information specialists, has enhanced identity authentication procedures), company spinout (the EFIT-V facial recognition suite from VisionMetric Ltd fundamentally changed the means by which facial composites are created and is now used by more than 85% of Britain's Police Forces), leadership of the development of standards for the expanding commercial marketplace (e.g. establishment of standards for image acquisition for e-passports and other access control applications) and policy-level input to Government and International Professional Bodies, providing long-term support for practical deployment and end- user engagement (the Biometrics Assurance Group with Fairhurst as an independent member reported the security risk and problems identifying fingerprints within the UK government's £5.6bn ID card scheme proposal).
Frowd's research aims to understand the extent to which witnesses and victims of crime construct accurate facial composites (pictures of criminal's faces), and to develop techniques which maximize the effectiveness of composites, thus allowing the police to identify as many offenders as possible using this type of forensic evidence. The principal impact involves a software system (EvoFIT), a new interview (Holistic-Cognitive Interview, H-CI) and two formats (animated caricature and stretched composite) for the police to publish composites in the media. In the audit period, these advancements have been used by police forces in the UK, US, Romania and Israel.
Modern processor architectures (networked multi/many-core nodes), together with society's expectation of evermore-complex applications, require fluent mastery of concurrency. To enable this mastery, in the last two decades our group has taught, researched and developed fundamental notions of concurrency, new programming languages (occam-pi, and the KRoC toolset), libraries (JCSP, CCSP, C++CSP, CHP), runtime systems (the KRoC/CCSP multicore scheduler) and tools based on formal process algebra (Hoare's CSP, and Milner's pi-calculus).
Our work has had impact in providing new mechanisms for software development in a number of sectors such as chip design, large-scale real-time systems, formal interfaces and testing and the space industry. Testimonials supporting this are available from a variety of industrial and commercial sources (NXP Semiconductors, Big Bee Consultants, Philips Healthcare, 4Links Ltd. and Microsoft Research Cambridge). The breadth of impact of the work is evidenced by download statistics, as well as by third-party contributions to libraries and documentation.
This research, which examines police investigatory methods to identify police suspects has directly increased suspect identification rates by the Metropolitan Police Service (MPS). It led to the MPS establishing a register of `super-recognisers' - officers particularly skilled at identifying faces from CCTV footage - and changed practices. Dissemination of the research, also well-publicised in the media, has influenced national policy makers. There is worldwide interest and secured European funding for a test to identify super-recognisers amongst police cohorts. The research is also improving recognition of EFIT-V images, the facial composite system used by most UK police forces. Dr Davis is disseminating his findings through the training course that operators have to complete to be certified to produce composites in real police investigations. He is also contributing to economic impact by enhancing the EFIT-V product.
We have established a primate research centre (The Macaque Study Centre) in a zoo environment (Marwell Zoo) for research into primate social cognition. Visitors can watch the science taking place, which 1) significantly increases their perception of the zoo as a place of learning, 2) increases their knowledge about the specific research being conducted, and 3) improves children's attitudes to science as an exciting subject. Marwell Zoo integrate the research into their educational workshops, and similar facilities are now being established in other zoos in light of the demonstrable scientific, public engagement/involvement and animal welfare benefits.
Our research on speech synthesis is embodied in software tools which we make freely available. This has led to widespread use and commercial success, including direct spinouts, follow-on companies and use by major corporations. This same research benefits people who lose the ability to speak and have to rely on computer-based communication aids. Unlike existing aids, which provide a small range of inappropriate voices which are often not accepted by users, our technology can uniquely create intelligible and normal-sounding personalised voices from recordings even of disordered speech, and so enable people to communicate and retain personal identity and dignity.
World-leading primate research by the `Origins of Mind' group led to the creation of the University's £1.6M `Living Links to Human Evolution' Research Centre, intentionally located in Edinburgh Zoo where it has pioneered unique public engagement and science education using a range of materials and activities. The research has thus impacted on: i) society and culture: since 2008, around 250,000 visitors per year have engaged with live, on-going science and multiple associated legacy resources and activities; ii) educational practitioners and school children, through classes in the Centre and internet teacher packs that integrate with Scottish Highers; and iii) commercial income to the Zoo.
Molecular dynamics (MD) simulations are used extensively in chemistry, biology and material sciences, placing huge demands on computer resources. Because these simulations explore the behaviour of molecules at defined ambient temperature, temperature control (thermostatting) is an essential element of MD algorithms. In a series of papers published from 2009 on, Leimkuhler (Maxwell Institute) and his collaborators developed improved numerical methods for temperature control. They proposed new algorithms and analysed their properties (such as fidelity to the dynamical model, efficiency and stability). The new algorithms have since been implemented in the world's leading MD software packages including DL-Poly, AMBER, NAMD and Accelrys's Material Studio. The research has had clear economic impact on the commercial company Accelrys by improving its product, and more broadly on the community of MD code users worldwide by providing improved simulation tools.
This Keele University research into advanced signal processing and classification methods has led to novel algorithms capable of isolating subtle patterns in complex data. This has been applied in two highly significant application areas: first to the problem of image source identification and second to the problem of unobtrusive but highly secure authentication methods. In the first case this has enabled images captured by mobile phone cameras to be reliably and evidentially linked to source devices. This has huge applicability to those fighting terrorism, paedophile rings and civil unrest by extending detection capabilities to mobile phones in an era in which they are rapidly replacing dedicated cameras. It helps to prove, for example, that a photograph entered as evidence was captured by a specific mobile phone. As most phones can be tied to their user or owner this is extremely important to the successful detection and prosecution of offenders.
In the second case it has enabled criminal record checks to be carried out securely online where previous paper-based systems were both too slow for purpose (taking weeks or months) and inherently insecure, leaving key posts unfilled in the health care industries and education sector; so benefitting the public by solving a problem that was having a negative impact on the running of these public services.
