  • Whidborne, James F. (IEEE, 1992-05-01)
    A performance index for control systems has been defined as the supremum of the absolute error that occurs over all time and all inputs. The input to the system is known only to the extent that it belongs to a known function ...
  • Whidborne, James F. (Elsevier, 1993-09-01)
    For the effective operation of a magnetically levitated (maglev) vehicle using electro-magnetic suspension, it is necessary that the airgap between the guideway and the levitating magnets is maintained. Such systems, where ...
  • Whidborne, James F.; Postlethwaite, I.; Gu, Da-Wei (IEEE, 1994-12-01)
    A new approach to robust controller design is proposed. By using plant-weighting functions as the design parameters, the approach combines the method of inequalities with robust stabilization of normalized coprime factor ...
  • Balboa, Itziar; Tatam, Ralph P. (SPIE - International Society for Optics and Photonics, 1998-07-20)
    A low coherence speckle interferometer implemented using single mode optical fibre and a multimode laser diode as a pseudo-low coherence source is described. The design of the interferometer is presented and demonstrated ...
  • Ivey, P. C.; Grant, K. R.; Lawson, Craig (University of Cambridge, 2002)
    High Cycle Fatigue (HCF) has been established as the major common failure mode in the US Air Force large fleet of aero-engines. Corrective measures for this failure mode in themselves deliver additional technical, managerial ...
  • af Wåhlberg, Anders (2002-10-23)
    A new area of traffic education, training in fuel efficient driving, is reviewed. This training is often said to reduce fuel consumption, accidents, emissions, and wear and tear on vehicles. These claims, made mainly by ...
  • Nobes, David S.; Ford, Helen D.; Tatam, Ralph P. (SPIE - International Society for Optics and Photonics, 2003-08-03)
    The development of a planar Doppler velocimetry is described. The technique is capable of measuring the three, instantaneous components of velocity in two dimensions using a single pair of signal and reference cameras. ...
  • Xiradakis, N; Li, Yiguang (ASME, 2004)
    Accurate gas turbine diagnosis relies on accurate measurements from sensors. Unfortunately, sensors are prone to degradation or failure during gas turbine operations. In this paper a stack of decentralised artificial neural ...
  • Casaubieilh, P.; Ford, Helen D.; Tatam, Ralph P. (SPIE - International Society for Optics and Photonics, 2004-06-09)
    An optical fibre, Fizeau configuration Optical Coherence Tomography (OCT) system is presented in this paper. The interferometer is formed between the distal end of the sample-arm fibre and the sample itself. This ensures ...
  • Li, Yiguang (ASME, 2004-07)
    Gas Path Analysis (GPA) and its different derivatives have been developed for more than thirty years and used widely and successfully by many gas turbine manufacturers and operators. In gas turbine gas path component ...
  • Hammond, David (2005-06-06)
    Dr David Hammond is a senior lecturer in Aerospace Engineering having joined Cranfield University in March 2002. Before this he worked for 14 years in the Sowerby Research Centre, the central corporate research centre for ...
  • Esteban, Jaime; Starr, Andrew G.; Willetts, Robert; Hannah, Paul; Bryanston-Cross, Peter (Springer, 2005-06-21)
    This paper reviews the potential benefits that can be obtained by the implementation of data fusion in a multi-sensor environment. A thorough review of the commonly used data fusion frameworks is presented together with ...
  • Charrett, Thomas O. H.; Ford, Helen D.; Tatam, Ralph P. (IOP Publishing, 2006)
    Two frequency planar Doppler Velocimetry (2ν-PDV) is a modification of the Planar Doppler Velocimetry (PDV) method that allows velocity measurements to be made, quickly and non intrusively, across a plane defined by a laser ...
  • Charrett, Thomas O. H.; Ford, Helen D.; Tatam, Ralph P. (AIAA, 2006)
    A modified Planar Doppler Velocimetry (PDV) technique, two frequency PDV (2v-PDV), is described that allows measurements of the velocity field over a plane defined by a laser light sheet using sequential illumination of ...
  • Zbikowski, Rafal; Ansar, Salman A.; Knowles, Kevin (IOP Publishing, 2006-07-10)
    This paper discusses several aspects of mathematical modelling relevant to the flight dynamics of insect flight in the context of insect-like flapping wing micro air vehicles (MAVs). MAVs are defined as flying vehicles ...
  • Khan, M. A.; Starr, Andrew G. (British Institute of Non-destructive Testing, 2006-08-01)
    Modern high speed and power machinery components like gears, bearings, pumps, hydraulics and motors normally suffer from wear phenomena during operation. The study of wear debris can help estimate the condition of the ...
  • Guenov, Marin; Lockett, Helen L. (Design Society, 2007)
    In today's competitive market many consumer products are designed with complex curved shapes to meet customers' demands for styling and ergonomics. These styled products are commonly manufactured using moulding processes ...
  • Smith, A; Jolly, Mark (Minerals, Metals & Materials Society, 2007)
    Hot tearing propensity in aluminium alloys is commonly measured using dog-bone and ring tests. Hot tearing occurs as a result of a number of factors including; level of stress and strain, hot spots and nucleation sites. ...
  • Cowling, Ian D.; Yakimenko, Oleg A.; Whidborne, James F.; Cooke, Alastair K. (IEEE, 2007-02-02)
    The paper proposes a complete real-time control algorithm for autonomous collision-free operations of the quadrotor UAV. As opposed to fixed wing vehicles the quadrotor is a small agile vehicle which might be more suitable ...
  • Dunn, Steve; Tiwari, Divya; Jones, Paul M.; Gallardo, Diego E. (Royal Society of Chemistry, 2007-09-25)
    Recently there has been great interest in using patterned ferroelectric materials for the photochemical growth of metal nanostructures. Variations in surface and sub-surface structure influence the photochemical processes. ...
