However, uncertainties in economic feasibility and environmental and social outcomes act as a bottleneck to its widespread uptake. Here, we present a decision support tool which aims to reduce these uncertainties by assisting site operators in assessing the economic, environmental and social consequences of a proposed project, while also evaluating the best technology train to use and the amount of rare earth elements present. Such a tool is the first of its kind and we propose its use as an initial assessment aid prior to more complex modelling of project feasibility in order to increase the uptake of enhanced landfill mining practices in the field of sustainable waste management.Item Open Access A Design Approach to IoT Endpoint Security for Production Machinery Monitoring(Cranfield University, 2019-05-22 16:09) Tedeschi, Stefano; Emmanouilidis, Christos; Mehnen, Jörn; Roy, RajkumarThe Internet of Things (IoT) has significant potential in upgrading legacy production machinery with monitoring capabilities to unlock new capabilities and bring economic benefits. However, the introduction of IoT at the shop floor layer exposes it to additional security risks with potentially significant adverse operational impact. This project addresses such fundamental new risks at their root by introducing a novel endpoint security by design approach. The approach is implemented on a widely applicable production machinery monitoring application by introducing real time adaptation features for IoT device security through subsystem isolation and a dedicated lightweight authentication protocol.Item Open Access A Fibre Optic Long Period Grating Immunosensor for Campylobacter jejuni with Enhanced Sensitivity by Bacterial Staining(Cranfield University, 2018-10-22 10:29) Rendon Romero, AntonioPoster presented at the Cranfield Doctoral Network Annual Event 2018. Campylobacteriosis is one of the most widely reported bacterial cause of gastroenteritis in humans in the world. One of the bacterial species that most causes the disease is Campylobacter jejuni. The detection of Campylobacter jejuni by sensitising the surface of an optical fibre long period grating (LPG) with covalently attached rabbit polyclonal antibody is explored. The sensitivity of the sensor is enhanced by bacterial staining allowing the detection of concentration as low as 102CFU/mL. Finally, the selectivity of the sensor against other bacterial species is evaluated.Item Open Access A head mounted augmented reality design practise for maintenance assembly(Cranfield University, 2021-08-18 17:03) Ariansyah, DedyThis is the experimental data used to examine the impact of different AR HMD modalities on task performance, system usability, and user safetyItem Open Access 'A Holistic Cabin Conceptualisation Approach (HCCA) framework'(Cranfield University, 2023-11-01 09:50) Kirensky, Roman; Lawson, Craig; Orson, BenThe presented toolset defines the stakeholders involved in aircraft passenger cabin interior development projects, and their pursued design drivers. - Stakeholder Definition sheet presents all types of organisations involved in the design of aircraft cabin interiors, disregarding of the involvement extent. - Stakeholder Analysis sheet contains the pairwise comparison matrices for all stakeholders along the influence and interest axes, and the resulting plot. - Cabin Design Drivers sheet contains the definition of drivers pursued by the cabin interior projects.

The spectrometer has a tuning range from 10 €“ 13 um (1,000 €“ 769 cm-1) and is designed to target volatile organic compounds (VOCs) which often exhibit water-free molecular absorption within the region. The spectrometer utilizes a hollow silica waveguide gas cell which has an internal volume of a few millilitres, a fast response time (~1 s), and is advantageous when only low sample volumes, similar to the cell volume, are available.Item Open Access A Method to Assess the Performance of SAR-derived Surface Soil Moisture Products(Cranfield University, 2021-04-13 09:13) Beale, John; Waine, Toby; Corstanje, Ronald; Evans, JonathanA Method to Assess the Performance of SAR-derived Surface Soil Moisture Products John Beale, Toby Waine, Jonathan Evans, Ronald Corstanje This study brought together existing research data obtained from a number of different sources, some of which were upon request and subject to licence restrictions.

Ongoing research on superheated/supercritical geothermal system, potentially representing a intensive amount of energy, is developed in Europe notably the Iceland Deep Drilling project (IDDP). The well IDDP-1, which reached a magma intrusion at a depth of 2100 m, raised new opportunities to untap the geothermal potential near shallow magmatic intrusions. Given their highly corrosive nature, geothermal fluids weaken the wellbore’s integrity during conventional geothermal production. Deep Borehole Heat Exchangers (DBHE) that do not require fluid exchange between the surface and the wells represent a strategic alternative to recovering heat from these unconventional geothermal resources, while minimising the risk of in-situ reservoir damage. The thermal influence and heat recovery associated with a hypothetical DBHE drilled into the IDDP geological settings were investigated via Computational Fluid Dynamics (CFD) techniques until 10 years of production, when the system reaches full equilibrium. Two wellbore designs were simulated, based on simplified geological properties from the IDDP-1 well description. The results show that, during the first year of production, the output temperature is function of the working fluid velocity before reaching pseudo-steady state behaviour. The cooling perturbation near the bottom hole is shown to grow radially from 10 to 40 m between 1 and 10 years of production, and the output thermal power calculated after 10 years reaches 1.2 MW for a single well.Item Open Access A Paradigm Shift Toward Zero Accident(Cranfield University, 2017-09-22 08:36) Soltani, AmirmasoudPresented at the "Future of Transportation" World Conference, July 2017, Cologne, Germany.Item Open Access A Physics-Based Modelling and Control of Greenhouse System Air Temperature Aided by IoT Technology(Cranfield University, 2023-03-14 09:53) Ayoola Faniyi, Beatrice; Luo, Jerry25th May, 2022 data set.
