A two-dimensional flood inundation model called LISFLOOD-FP, which was created by a team led by Professor Paul Bates at the University of Bristol, has served as a blueprint for the flood risk management industry in the UK and many other countries. The documentation and published research for the original model, developed in 1999, and the subsequent improvements made in over a decade of research, have been integrated into clones of LISFLOOD-FP that have been produced by numerous risk management consultancies. This has not only saved commercial code developers' time but also improved the predictive capability of models used in a multimillion pound global industry that affects tens of millions of people annually. Between 2008 and 2013, clones of LISFLOOD-FP have been used to: i) develop national flood risk products for countries around the world; ii) facilitate the pricing of flood re-insurance contracts in a number of territories worldwide; and iii) undertake numerous individual flood inundation mapping studies in the UK and overseas. In the UK alone, risk assessments from LISFLOOD-FP clones are used in the Environment Agency's Flood Map (accessed on average 300,000 times a month by 50,000 unique browsers), in every property legal search, in every planning application assessment and in the pricing of the majority of flood re-insurance contracts. This has led to more informed and, hence, better flood risk management. A shareware version of the code has been available on the University of Bristol website since December 2010. As of September 2013, the shareware had received over 312 unique downloads from 54 different countries.
The School of Mathematics at Cardiff University has developed important statistical and mathematical models for forecasting consumer buying behaviour. Enhancements to classical models, inspired by extensively studying their statistical properties, have allowed us to exploit their vast potential to benefit the sales and marketing strategies of manufacturing and retail organisations. The research has been endorsed and applied by Nielsen, the #1 global market research organisation that provides services to clients in 100 countries. Nielsen has utilised the models to augment profits and retain their globally leading corporate position. This has led to a US$30 million investment and been used to benefit major consumer goods manufacturers such as Pepsi, Kraft, Unilever, Nestlé and Procter & Gamble. Therefore the impact claimed is financial. Moreover, impact is also measurable in terms of public engagement since the work has been disseminated at a wide range of national and international corporate events and conferences. Beneficiaries include Tesco, Sainsbury's, GlaxoSmithKline and Mindshare WW.
Now-casting is the prediction of the present, the very near future, and the very recent past. It has been developed within a research programme led by Lucrezia Reichlin at LBS. It is relevant because key economic statistics, particularly quarterly measures such as GDP, are available only with a delay. Now-casting exploits information which is published early and at higher frequencies than the target variable and generates early estimates before the offb01cial fb01gures become available.
Now-casting has signifb01cant infb02uence and impact. The techniques reported in this case study are in widespread use by central banks and policy institutions. Furthermore, this research has achieved successful commercial impact via Now-Casting Economics Limited.
This impact case study describes the development and application of models of training and performance in elite cycling. These models have been used by elite medal winning teams in their search for competitive advantage in the UK (by British Cycling and British Triathlon, including the GB Olympic Cycling and British Triathlon Teams and the British Paralympic Team) and internationally (by the Australian Institute of Sport). These new cycling models have provided the basis for the development of new training processes that are influencing the way in which many nations prepare their elite riders. This work has contributed directly to enhance elite sports science practice in the field of cycling and the competitive advantage for British teams to which it contributes is envied around the world. The adoption of the underlying algorithms for the `Wattbike' software has given our work a wider impact on sports practice and training methods, and it has been adapted for the `Map My Tracks' website which is used by sports enthusiasts worldwide.
Pratt & Whitney (one of the world's largest makers of aircraft engines) has developed a process, "Design for Variation" (DFV), that uses Bayesian methods developed at Sheffield for analysing uncertainty in computer model predictions within the design, manufacture and service of aircraft engines. The DFV process significantly improves cost efficiency by increasing the time an engine stays operational on the wing of an aircraft, so reducing the time that the aircraft is unavailable due to engine maintenance. DFV also saves costs by identifying design and process features that have little impact on engine performance, but are expensive to maintain. Pratt & Whitney estimate the DFV process to generate savings, for a large fleet of military aircraft, of [text removed for publication].
The UK Food and Environment Research Agency (Fera) has used these methods in their risk analyses, for example in assessing risks of exposure to pesticides.
Ocean circulation accounts for much of the energy that drives weather and climate systems; errors in the representation of the ocean circulation in computational models affect the validity of forecasts of the dynamics of the ocean and atmosphere on daily, seasonal and decadal time scales. Research undertaken by the University of Reading investigated systematic model errors that resulted from data assimilation schemes embedded in the key processes used to predict ocean circulation. The researchers developed a new bias correction technique for use in ocean data assimilation that alleviates these errors. This has led to significant improvements in the accuracy of the forecasts of ocean dynamics. The technique has been implemented by the Met Office and by the European Centre for Medium Range Weather Forecasting (ECMWF) in their forecasting systems, resulting in major improvements to the prediction of the weather and climate from oceanic and atmospheric models. The assimilation technique is also leading to better use of expensively acquired satellite and in-situ data and improving ocean and atmosphere forecasts used by shipping and civil aviation, energy providers, insurance companies, the agriculture and fishing communities, food suppliers and the general public. The impact of the correction procedure is also important for anticipating and mitigating hazardous weather conditions and the effects of long-term climate change.
This impact case study is based on a Knowledge Transfer Partnership (KTP) between the School of Mathematics, Statistics and Actuarial Science, University of Kent and KROHNE Ltd, a world leading manufacturer of industrial measuring instruments. These precision instruments (typically flow meters and density meters) need to be calibrated accurately before being used and this is an expensive and time-consuming process.
The purpose of the KTP was to use Bayesian methodology developed by Kent statisticians to establish a novel calibration procedure that improves on the existing procedure by incorporating historical records from calibration of previous instruments of the same type. This reduces substantially the number of test runs needed to calibrate a new instrument and will increase capacity by up to 50%.
The impact of the KTP, which was graded as `Outstanding', has been to change the knowledge and capability of the Company, so that they can improve the performance of their manufacturing process by implementing this novel calibration method. This has been achieved by adapting the underpinning Kent research to the specific context of the calibration problem, by running many calibrations to demonstrate the effectiveness of the method in practice, and by supporting the implementation of the new calibration method within the Company's core software.
Moreover, the project has changed the Company's thinking on fundamental science, particularly industrial mathematics. The value of historical data, and the usefulness of Bayesian methods, is now widely appreciated and training for staff in Bayesian Statistics is being introduced. Thus the project has not only changed the protocols of the Company, it has also changed their practice.
Developed at Essex, the `BioAid' app transforms iPhones and iPods into fully functional hearing aids. The app provides readily-available and cost effective access to hearing aid technology, allowing users to test its settings at their own pace in their everyday environments. BioAid is the culmination of a research programme that has systematically built computational simulations of different types of hearing loss and developed biologically-realistic algorithms to compensate for these impairments. Launched as an open-source app in December 2012, by 31st July 2013 it had been downloaded by more than 20,000 users in over 90 countries. Over various periods in that time, BioAid has also been iTunes' most downloaded medical app in 11 countries.
PREDICT is a prognostication and treatment benefit decision aid aimed at aiding the breast cancer multi-disciplinary team in the management of women with early breast cancer. The user-friendly, web-based tool was developed in collaboration with the Cambridge Breast Unit multi-disciplinary team, the Eastern Cancer Registration and Information Centre. Implemented online, PREDICT is hosted on a NHS web-server. Since 2012 PREDICT has been used widely by clinicians throughout the UK and world-wide.
Neuberger, together with David McCarthy (Imperial), who, in their earlier work, had raised concerns about the sustainability of the Pensions Protection Fund (PPF), were commissioned by the Fund to conduct research on alternative levy structures. This led to the development of a new risk-based levy structure, which was implemented over the years 2012-2013. This research and its resulting impact have not only shaped how the PPF operates in ensuring the levy's burden is fairly shared, but has also benefited all UK holders of occupation based pensions and the taxpayer at large.
