  • Observing gravitational-wave transient GW150914 with minimal assumptions 
    Abbott, B. P.; Davies, G. S.; LIGO Scientific Collaboration and Virgo Collaboration (American Physical Society, 2016-06)
    The gravitational-wave signal GW150914 was first identified on September 14, 2015, by searches for short-duration gravitational-wave transients. These searches identify time-correlated transients in multiple detectors ...
  • Obsidian exchange networks and highland-lowland interaction in the Lesser Caucasus Borderlands 
    Erb-Satullo, Nathaniel L.; Rutter, Matilda; Frahm, Ellery; Jachvliani, Dimitri; Albert, Paul G.; Smith, Victoria C. (Elsevier, 2023-05-09)
    Obsidian sourcing studies have a long history in the Near East, but relatively few have focused on obsidian exchange after the Early Bronze Age. Here, we present a multi-technique analysis of an assemblage of 111 obsidian ...
  • Obstacle voidance for Unmanned Aerial Vehicles during teleoperation 
    Courtois, Hugo (2019-09)
    Unmanned Aerial Vehicles (UAVs) use is on the rise, both for civilian and military applications. Autonomous UAV navigation is an active research topic, but human operators still provide a flexibility that currently matches ...
  • Occupational limbo, transitional liminality, and permanent liminality: new conceptual distinctions 
    Bamber, Matthew; Allen-Collinson, Jacquelyn; McCormack, John (SAGE, 2017-06-12)
    This article contributes new theoretical perspectives and empirical findings to the conceptualization of occupational liminality. Here, we posit ‘occupational limbo’ as a state distinct from both transitional and permanent ...
  • Offset in a post-Brexit world 
    Matthews, Ron; Anicetti, Jonata (Taylor & Francis, 2022-01-06)
    Prior to the launch of the European Procurement Directive, the UK’s erstwhile offset model was hailed a success. However, the directive compelled the UK to abandon its approach as the intention of the European Commission ...
  • On differences in the equation-of-state for a selection of seven representative mammalian tissue analogue materials 
    Appleby-Thomas, Gareth J.; Fitzmaurice, Brianna; Hameed, Amer; Painter, Jonathan; Gibson, Michael C.; Wood, David C.; Hazael, Rachael; Hazell, Paul J. (Elsevier, 2017-10-10)
    Tissue analogues employed for ballistic purposes are often monolithic in nature, e.g. ballistic gelatin and soap, etc. However, such constructs are not representative of real-world biological systems. Further, ethical ...
  • On recognition of gestures arIsing in flight deck officer (FDO) training 
    Turan, D (Engineering Systems Department, 2011-01-11)
    This thesis presents an on-line recognition machine RM for the continuous and isolated recognition of dynamic and static gestures that arise in Flight Deck Officer (FDO) training. This thesis considers 18 distinct and ...
  • On the behaviour of porcine adipose and skeletal muscle tissues under shock compression 
    Wilgeroth, J. M. (DEAS, 2014-06-10)
    The response of porcine adipose and skeletal muscle tissues to shock compression has been investigated using the plate-impact technique in conjunction with manganin foil pressure gauge diagnostics. This approach has ...
  • On the Characteristics of a Twin-Jet STOVL Fountain 
    Saddington, A. J.; Knowles, Kevin; Cabrita, P. M. (2015-03-03)
    The interaction of multiple jets with the ground is of great importance for the design and operation of short take-off, vertical landing aircraft. The fountain upwash flow, generated by the impingement of two ...
  • On the derivation and analysis of decision architectures for unmanned aircraft systems 
    Patchett, C H (2013-10-08)
    Operation of Unmanned Air Vehicles (UAVs) has increased significantly over the past few years. However, routine operation in non-segregated airspace remains a challenge, primarily due to nature of the environment and ...
  • On the design of hybrid simulation models, focussing on the agent-based system dynamics combination 
    Swinerd, C. (2014-08-15)
    There is a growing body of literature reporting the application of hybrid simulations to inform decision making. However, guidance for the design of such models, where the output depends upon more than one modelling paradigm, ...
  • On the dynamic behavior of three readily available soft tissue simulants 
    Appleby-Thomas, Gareth J.; Hazell, P. J.; Wilgeroth, J. M.; Shepherd, C. J.; Wood, D. C.; Roberts, A. (American Institute of Physics, 2011-12-31)
    Plate-impact experiments have been employed to investigate the dynamic response of three readily available tissue simulants for ballistic purposes: gelatin, ballistic soap (both subdermal tissue simulants), and lard ...
  • On the effects of powder morphology on the post-comminution ballistic strength of ceramics 
    Appleby-Thomas, Gareth J.; Wood, D. C.; Hameed, Amer; Painter, Jonathan; Fitzmaurice, Brianna C. (Elsevier, 2016-10-29)
    In this paper in order to try and elucidate the effects of particle morphology on ballistic response of comminuted systems, a series of experiments were carried out via the use of powder compacts with differing initial ...
  • On the importance of the bullet jacket during the penetration process: reversed-ballistic experimental and numerical study 
    Lesmana, Denny; Arifurrahman, Faizal; Hameed, Amer; Appleby-Thomas, Gareth J.; Santosa, Sigit P. (Springer Verlag, 2020-04-30)
    The behaviour of exposed and copper-jacketed 12.7 mm En8 steel cores impacting against 5 and 9 mm Armox Advance plates was investigated to determine the significance of the jacket during the penetration. The target plates ...
