How to Predict the Vibration Energy Dissipation of Bolted Joint?

Damien Lancereau
3MT presented at the 2017 Defence and Security Doctoral Symposium.
The objective of this PhD is to investigate and understand the dynamics of joints in built-up structures. Currently, we do not understand the influence of the joints on the damping or the stiffness of a system. Our work will try to improve the quality of dynamics in finite element simulations. The aeronautic industry is currently limited in there design by the lake of dynamic joint model....

What is Where? Visual Understanding for Autonomous Cars

Amélie Grenier
Autonomous driving has been rapidly evolving for the last few years and there is a lot of fervour in increasing the intelligence of these vehicles. One key aspect of a self-driving car is its ability to sense the environment in order to be aware of its surroundings and consecutively take better decisions.
While the right combination of sensors is widely debated, my research interest lies in using computer vision and machine learning techniques to detect, localise...

Effects of particulate contamination and jet fuel chemistry on the nucleation of water and ice in aircraft fuel systems

Judith Ugbeh
3MT presented at the 2018 Defence and Security Doctoral Symposium.
The contamination and behaviour of water in aircraft fuel systems remains a significant area of global research interest following several aircraft incidents. Water and particulates in fuel may lead to ice formation. The resulting ice formed may eventually block the fuel filters and feed pipes creating safety problems.In order to engineer a lasting solution to the problem of ice in jet fuel it is important to...

I feel it in my bones! An investigation into the mechanical and structural changes to bone as we age

Hannah McGivern
3MT presented at the 2017 Defence and Security Doctoral Symposium.
Bone biomechanics is concerned with the study of the ailments and performance of our musculoskeletal system. Our knowledge of this field has been propelled forward by those in the automotive industry, who specialise in applied biomechanics and engineering. Their interest in this subject matter stems from the continual need to improve vehicle safety, but our skeletons also provide anthropological records of our lives, and can even...

An Introduction to Intelligence Engineering: Operating Beyond the Conventional

Adam Svendsen
Contemporary defence and security enterprise efforts can be viably improved. With an overarching focus on ‘ways’, ‘means’, up and across to realising operational and strategic-ranging ‘ends’, this presentation advances a substantially-structured, multi-scaler ‘Intelligence Engineering’ (IE)-based framework and ‘step-by-step’ toolbox useful for both deployment and employment for a multitude of purposes - essentially whatever is to be accomplished.

As the presentation goes on to reveal, the IE framework can contribute towards helping progress several tasks, such...

Deep Learning Techniques for Missile Seeker Automatic Target Recognition

Samuel Westlake
Modern infrared missiles use sophisticated computer vision techniques, in conjunction with imaging seekers, to automatically detect and localise targets. However, simulations show that soft-kill countermeasures remain an effective defence against such systems. This research explores the feasibility of deep learning algorithms for Automatic Target Recognition (ATR) and aim to significantly improve seeker performance in the presence of soft-kill countermeasures and clutter. State-of-the-art neural network architectures were benchmarked using both simulated and real-world infrared data. Their...

Artificially Intelligent Targeting

Samuel Westlake
The aim of this project is the development of new techniques for infrared anti-ship missile seekers. This image illustrates how we are using deep learning to detect, recognise and classify multiple ships. Our algorithm can differentiate between military and civilian vessels, and is even robust against the presence of infrared countermeasures and background clutter.
In most cases, training deep learning algorithms requires thousands, if not millions, of carefully labelled examples. This presents a major challenge for...

The temperature effect on the cuticular chemical profile of Lucilia sericata blowfly larvae

Janan Kula
Forensic entomology has become increasingly important in the last decade. In cases of homicide, suicide or suspicious death, insect specimens are taken into consideration as acceptable evidence like blood, fingerprint or any other biological materials. When solving criminal cases, it is essential to determine the time since death or post-mortem interval (PMI). Entomological evidence can provide valuable information about the prediction of the post-mortem interval and where the death occurred.

Identifying more economical approaches to medical imaging for the rehabilitation of traumatic military injuries

Daniel Rothwell
The cost of National Health Service care for the 265 amputee casualties of British Operations in Afghanistan between 2003 and 2014 is projected to be £288 million (Edwards et al., 2015, Clinical Orthopaedics and Related Research). This cost is due to the development of secondary comorbidities such as osteoporosis, type 2 diabetes, obesity, and cardiovascular disease. An independent and physically active lifestyle can benefit health and prevent such diseases. Physical activity is restricted following lower...

Losing Contact with Nano-object

Safiah Binti Zulkifli
Micro-UAVs of the size of an insect can be used to perform stealthy surveillance or to gather intelligence crucial to attack roles at a relatively short range and within enclosed spaces and buildings. Conventional radar systems have been optimized to detect and classify bigger targets and are not specifically designed to detect micro-targets of less than 5cm in size. Other micro-targets that are relatively small in size are the insect itself. Insect detection have been...

Absence of Presence

Safiah Binti Zulkifli
The tiny the object, the more difficult it is to detect. Failed to detect does not simply signifies the absence of presence. The object may be camouflage and immersed in this huge world - as this image demonstrates! With a booming micro-drones easily available for all walks of life, it is hugely possible for these drones to perform stealthy surveillance being unnoticeable. But, wait! This fact can be avoidable with a specifically design radar for...

Predicting the Fate and Transport of Insensitive High Explosives in Soils

Encina Gutierrez Carazo
A great deal of studies on the environmental fate and transport of legacy explosives such as cyclotrimethylenetrinitramine (RDX), 2,4,6-trinitrotoluene (TNT) and 1,3,5,7-tetranitro-1,3,5,7-tetrazoctane (HMX) has been conducted. However, less is known about the behaviour of Insensitive High Explosive (IHE) constituents being brought into military service such as 2,4-dinitroanisole (DNAN) and 5-nitro-1,2,4-triazol-3-one (NTO) in soil and water environmental compartments. Typically fate and transport of explosives are often performed under controlled laboratory conditions. However, experimental data are often...

Adaptations to unaccustomed resistance training for women in physically demanding occupations

Stephen McGuire
Improvements in maximal strength may reduce injury risk and improve occupational performance. Women’s naturally lower muscular strength compared to men, can be offset through resistance training (RT), but research into its implementation has been limited. Therefore, the time-course of muscular adaptations is of interest, with evidence suggesting adaptations in size and strength are detectable as early as 3-4 weeks, concomitant with an attenuation of RT induced muscle damage. This evidence offers a reduction in the...
