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 Control for Motion Sickness Minimisation in Autonomous Vehicles(Cranfield University, 2018-10-22 10:13) Htike, ZawPoster presented at the Cranfield Doctoral Network Annual Event 2018. Autonomous vehicles or self-driving vehicles are expected to become a wide scale deployment for public use in the very near future. Recent study shown that there will be increase in frequency and severity of motion sickness due to engaging in non-driving tasks. This establishes motion sickness as being the elephant in the room and the increase in occurrence of motion sickness is predicting to be a limitation to the successful introduction of full vehicle automation. Motion sickness is a condition marked by symptoms of nausea dizziness, and other physical discomfort. The accepted cause of motion sickness is being the sensory conflict between inputs from the visual, vestibular and somatosensory systems of human body. Factors that might increase or decrease the severity of sickness symptoms includes ages, genders, alcohols, drugs, motion environments, other environmental and psychological aspect. Nevertheless, motion sickness in road vehicles is most closely related to low-frequency fore-and-aft, lateral, yaw acceleration. The range of these frequencies stated in the Standards guideline (International Standard, British Standards and Military Standards) for human exposed to whole-body mechanical vibration and shock, are in the range between 0.1 to 0.5 Hz. Previous experiments studies also shown that passenger motion sickness increases with increased exposure to lateral motion at low frequencies less than 0.5 Hz. This project aims to develop a control strategy that could minimise motion sickness in autonomous vehicles. The first part of the project explores the empirical formulations outlined in the Standards to evaluate motion sickness as a form of predicted illness rating or motion sickness incidence. A simple optimisation algorithm is developed to investigate the effectiveness of reducing motion sickness based from such formulations. The second part of the project looks at the sensory conflict theory for estimating motion sickness by adopting the existing 6-DOF subjective vertical conflict model. This model would later incorporate with vehicle model, and an optimal control strategy would be implemented to minimise motion sickness.Item Open Access IEEE sensors 2016 poster(Cranfield University, 2016-10-21 15:18) Barrington, James; James, Stephen; Tatam, Ralph; Partridge, MatthewConference poster for IEEE sensors 2016 conference.

Abstract: Optical interferometry is a widely used technique for ultra-precision distance measurements in many areas of science and technology, enabling fundamental physical experiments, such as the hunt for gravitational waves, and underpinning important industrial technologies, such as semiconductor fabrication. My particular research deals with the question on how multiple measurements at different points can be taken simultaneously using only one instrument. This can be achieved by appropriately modulating the optical wavelength of the laser used and a very simple way to perform these measurements is the signal processing technique developed during my PhD thesis project. A key advantage of this approach is that it reduces the number of optical components needed and instead shifts complexity of the measurements into the electronics, potentially enabling very cost-effective measurements. As this technology is very new many potential applications still remain unexplored.
