This case study concerns the design and methodology adopted in the construction of high reliability (safety-critical and real-time) embedded systems, particularly as applied in the automotive and avionics industry. The key impact has been for the automotive and avionics industry to adopt a change in the way these systems are designed, leading to more reliable systems, faster time to market, lower production and verification costs, and lower maintenance costs.
The subject matter concerns the fundamental architecture of high reliability embedded systems. Specifically it is a paradigm shift in the theoretical design of the software and hardware from established event-driven architectures to novel time-triggered architectures developed at the University of Leicester (UoL). The novel paradigm is supported by a range of development tools, processor designs, and diagnostic/maintenance tools developed by a spin-out company, TTE Systems Ltd. Research was exploited commercially by TTE Systems Ltd to provide economic impact via software tools sales, consultancy services, bespoke product development, and training courses.
Building on research in integrated information systems and their impact on organisational culture, Newcastle Business School (NBS), via a two-year Knowledge Transfer Partnership (KTP 8193), assisted Inpipe Products (IPP) to increase its operational efficiency and turnover. IPP is a world leading company in the design, manufacture, supply and rental of pipeline maintenance equipment for the global oil and gas industry. The KTP explored and developed the cultural environment for successful implementation of an integrated information system. The result for the company is improved operational efficiency, with the processing time for products from sales to engineered drawings reduced from five hours to 15 minutes, a reduction in late deliveries due to better information on product specification and a 14% reduction in rejected products. Product sales turnover has increased from £5.5 million to £6 million per year.
Helicon Health is a UCL spin-out company providing a stroke prevention clinical management service (Helicon Heart) developed through UCL health informatics research. In partnership with Whittington Health, a large north London hospital, Helicon Heart provides stroke prevention management to 5 NHS Clinical Commissioning Groups (CCG) across north London and Hertfordshire, covering 2 Hospital Trusts, 30 General Practice delivery sites and 3 Community Pharmacies. The system underpins clinical care for 3,000 at-risk patients, and Helicon Health has secured additional contracts to extend this to 4,500 patients in 2014. Every prevented stroke saves the NHS £16,000 per annum; the estimated saving to each CCG is approximately £500,000 per annum, to which the Helicon Heart service makes a significant contribution.
Building on excellent computer science research, carried out in a number of applied research centres, the University has taken a leading role in the establishment and development of the software sector in the North East. This has resulted in a regional strategic approach, which has delivered significant social and economic benefits, with impacts including the creation of jobs, SME growth, cluster establishment and inward investment. Sunderland's applied computing research has also resulted in an increase in innovation and research in software SMEs and has impacted on the perception of Sunderland as the heart of a regional software cluster.
Health Technology Assessment (HTA) is a systematic approach to evaluating the safety, clinical and cost effectiveness of a drug/medical intervention into the NHS. Research and practice of HTA enabled Liverpool University to significantly impact and influence national and international health policy by optimising NHS decision-making on drug adoption and other clinical interventions, as well as disseminating HTA expertise and application around the globe. Reach is both geographical and organizational, spanning the UK NHS, the European, African and Asian healthcare systems, as well as with members of the Pharmaceutical industry. Numerous populations, from patients of the UK NHS, to world-citizens, benefit as a consequence of the application of health economics research.
Led by Professor Andrews, a computational method for real time mission planning, based on Binary Decision Diagrams (BDD), was developed in the Mathematical Sciences Department at Loughborough University (LU) from 1993-2003. This is fast and accurate and can be used to support decision-making on system utilisation in real-time operation, which has led to the ability to diagnose in flight faults for unmanned aerial vehicle (UAV) applications.
The research has changed the understanding and awareness of the advantages of BDD, resulting in integration into major industrial trials and proprietary software products, including at BAE Systems, one of the world's largest companies in an area of vital importance to UK security and economic development. The methodology has attracted significant research funding in collaborative programmes with industry.
A quiet technology revolution in the UK has been changing the way that police officers on the beat and hospital nurses access and record information, using handheld electronic notebooks that bring large time and cost savings. This revolution began as a University of Glasgow research programme and led to the creation of a successful spin-out company, Kelvin Connect. Acquired in 2011 by the UK's largest provider of communications for emergency services, Kelvin Connect has grown to 30 staff. Its Pronto systems are now in use by 10% of UK police forces and nursing staff in several UK hospitals.
The Network & Information Security Technology Lab (NISTL) at Liverpool John Moores University (LJMU) conducts research in securing networked systems against the growing threat of cyber crime. The research has generated a correlated set of new security protocols, novel system composition methods and efficient digital forensic analysis schemes for more effective layered security protection. Their main impacts for the period 01/2008 - 07/2013 are highlighted below:
In addition to the above direct impacts, our work is also beneficial to other organisations and even the general public, as they all require security techniques for information protection.
Research at the University of Portsmouth (UoP) has created new user-friendly control, navigation and communication systems for powered-wheelchairs that have made a significant and positive impact on the lives of users. These have given many disabled children and adults an opportunity for independent mobility, some for the first time.
The systems have been used in six special schools and institutions (including RNIB and NHS) and many private homes. Economic impact in reducing the need for carers alone has been estimated at more than £250,000 p.a and the devices have also changed some professional services.
Research in Sheffield since 1993 has focused on developing information-rich systems and services from a user-oriented perspective rather than a more technology-driven approach. This has ranged from the development of theoretical models that describe information behaviour and processes, to the design and evaluation of information-rich systems and services that are based on information behaviour models and that involve end users throughout the design process. The impact includes: (1) enhancements in the practices adopted in systems development within cultural heritage institutions (The National Archives, UK) and libraries (Online Computer Library Centre, US; M25 Consortium of Academic Libraries, UK), (2) improved support for further development and commercialisation of technologies by IT companies (Gnowsis, Austria; Intempra, Italy), and (3) downstream impacts in the form of knowledge transfer leading to new projects to further develop existing technologies and systems (led by Language Technology Centre, UK).
