2023 Defence and Security Doctoral Symposium (DSDS23) hosted by Cranfield University in conjunction with AWE: Symposium outputs
Permanent URI for this collection
This collection showcases outputs from the ninth Defence and Security Doctoral Symposium, hosted at the Defence Academy of the United Kingdom, Shrivenham by Cranfield University in association with AWE.
It is the only UK conference to provide research students and early career researchers in defence and security with an opportunity to present their work to a sector-wide audience. Covering both technology and social sciences research, contributions include paper presentations, a 3MT (three-minute thesis) competition, digital images and posters.
In addition, there are plenary talks from thought-leaders, as well as opportunities to interact with industry, publishers and other employers of defence and security researchers.

Academics who engage the subject either disagree that Trump developed a distinct foreign policy or agree that he did. Those who agree that he did, still disagree on the type and impact. Thus, the three key academic questions that underpin the Trump ‘America First’ foreign policy are: 1) How do we conceptualize the Trump ‘America First’ foreign policy? 2) What impact does it have on democracy and democratization? 3) How do state and non-state actors of democracy promotion respond effectively to this impact? This research makes conceptual and theoretical contribution to U.S foreign policy schools of thought and International Relations. It identifies five patterns in the Trump policy that provides the theoretically backed basis for re-conceptualization; 1) Pattern against international system/multilateral institutions; 2) Unilateral pattern; 3) Pattern against pro-democracy leaders; 4) Pro-Putin pattern; and 5) nick-naming/populist pattern. The study argues that a U.S foreign policy that displaces U.S stewardship of the international system and replaces the two main pillars of liberalism; multilateralism and globalism, with unilateralism and Americanism creates the conditions for global waves of autocratization and anarchy.Item Open Access Performance Characteristics and Permittivity Modelling of a Surface Plasmon Resonance Sensor for Non-destructive Metal Surface Monitoring in a Saline Maritime Environment(Cranfield University, 2024-01-24T12:38:05Z) Lavers, ChristopherPoster contribution to the Defence and Security Doctoral Symposium 2023Item Open Access Development of Sustainable PPE for Higher Threat Clearance Operations by Humanitarian Organisations(Cranfield University, 2024-01-17T17:58:27Z) Brown, Laura3MT contribution to the Defence and Security Doctoral Symposium 2023Item Open Access Is TNT Equivalency Still Useful?(Cranfield University, 2024-01-22T14:12:55Z) Alford, RolandPoster contribution to the Defence and Security Doctoral Symposium 2023Item Open Access Understanding and communicating deathwatch beetle activity on HMS Victory(Cranfield University, 2024-01-18T11:16:15Z) Harvey, Cathryn3MT contribution to the Defence and Security Doctoral Symposium 2023Item Open Access Assessment of the Conceptual and Moral Factors on the Outcome of Wars: An AI Perspective(Cranfield University, 2024-01-18T11:06:10Z) Yesilyurt, Gurkan3MT contribution to the Defence and Security Doctoral Symposium 2023Item Open Access Little layer.

Since hydrogen is a much lighter gas than methane, it is important to understand the change in parameters when transporting it. While most modern work in this topic looks at the transport of hydrogen-methane mixtures, this work focuses on pure hydrogen transport. The aim of this paper is to highlight the change in gas distribution parameters when natural gas is replaced by hydrogen in the existing infrastructure. This study uses analytical models and computational models to compare the flow of hydrogen and methane in a pipe based on pressure loss. The Darcy-Weisbach and Colebrook-White equations were used for the analytical models, and the k- ε model was used for the computational approach. The variables considered in the comparison were the pipe material (X52 Steel and MDPE) and pipe diameters (0.01me1m). It was observed that hydrogen had to be transported 250e270% the velocity of methane to replicate flow for a fixed length of pipe. Furthermore, it was noted that MDPE pipes has 2e31% lower pressure losses compared to X52 steel for all diameters when transporting hydrogen at a high velocity.Item Open Access Experimental Measurement of TNT Equivalency For Contact Charges(Cranfield University, 2024-01-19T12:36:00Z) Alford, RolandThe ability to compare explosives is fundamental. Numerous methods are used and while 10 simple conversion factors are often used, the use of TNT Equivalency (TNTe) is not a 11 simple subject as explosives exhibit very different equivalencies depending on whether the 12 pressure or impulse are being considered as well as other conditions. The scaled distance has 13 been found to have a significant effect on the TNTe but due to the difficulty of taking 14 measurements at very close ranges, no TNTe have been quoted for charges in direct contact 15 (Z=0). This paper describes the use of a ballistic pendulum to measure the impulse from 16 contact charges and presents some surprising results that require a two-stage propulsion, as 17 originally described by Backofen, to be explained.Item Open Access Polarimetrically augmented Coherent Change Detection three stage detector for laboratory multistatic Synthetic Aperture Radar(Cranfield University, 2024-01-19T12:41:39Z) Hagelberg, AlexanderPaper presentation to the Defence and Security Doctoral Symposium 2023Item Open Access Temperature-Bias Compensation of Low-Cost Inertial Sensors – Possible or Pipe Dream?(Cranfield University, 2024-01-19T15:42:05Z) Maton, DariuszNavigation using low-cost inertial sensors costing less than £1 each is generally considered impossible. With various measurement error contributions, the velocity and position estimates from these sensors drift exponentially with time. By simulating the sensor, we show how the zero bias error is the most serious contributor. The zero bias is known to change with temperature due to dissimilar thermomechanical characteristics of materials in the sensor’s construction and others have shown this trend to be nonlinear, exhibit hysteresis and unique to each sensor. This is a problem because it suggests error compensation by modelling (software level), or sensor redundancy (hardware level) will be ineffective. From temperature experiments on three of the same low-cost sensors, we show that temperature-bias responses are indeed unique and nonlinear but may be opposing between sensors. Furthermore, we show that one can get lucky and obtain a sensor with an axis that is relatively insensitive to temperature. This is encouraging because it supports the idea that an inertial measurement unit comprised of an array of inertial sensors can be fused to provide higher accuracy measurements than a single sensor operating alone. Lastly, we identify a threat to this idea we call temperature shock and suggest how it can be avoided. While the contributions of this work are intended to improve the accuracy of human position tracking, their impact extends to any field where lengthy periods of position tracking under Global Positioning System (GPS) denial is required.Item Open Access Protecting Publicly Accessible Locations from Terrorism: Towards a strategic framework for Kenya(Cranfield University, 2024-01-19T14:43:39Z) Olela, JamesPaper presentation to the Defence and Security Doctoral Symposium 2023Item Open Access Development of Sustainable PPE for Higher Threat Clearance Operations by Humanitarian Organisations(Cranfield University, 2024-01-22T10:08:40Z) Brown, LauraPoster contribution to the Defence and Security Doctoral Symposium 2023Item Open Access The Phishing Game: An Analog Game To Defend UK Organisations From Phishing(Cranfield University, 2024-01-22T10:17:01Z) Henderson, NiklasPoster contribution to the Defence and Security Doctoral Symposium 2023
