  • Very efficient sampling technique for fiber-remote optical emission spectroscopy of aqueous solutions 
    MacKenzie, Steven J.; Hodgkinson, Jane; Johnson, Mark; Dakin, John P. (1997-01-01)
    We have measured fluorescence from a waveguide formed by a falling cylindrical stream of liquid. The configuration is suited to taking measurements from liquids with any refractive index, such as aqueous solutions. The ...
  • Very high-order methods for 3D arbitrary unstructured grids 
    Tsoutsanis, Panagiotis (Cranfield University, 2009-08)
    Understanding the motion of fluids is crucial for the development and analysis of new designs and processes in science and engineering. Unstructured meshes are used in this context since they allow the analysis of the ...
  • Vibration analysis of compressor blade tip-rubbing 
    Arzina, Dina (Cranfield University, 2011)
    There has been a significant increase in air traffic volume, particularly over the past twenty years. In order to cope with this increase in demand, it has been necessary to increase the efficiency of aircraft engines. ...
  • Vibration characteristics of a cantilever plate with swept-back leading edge 
    Heiba, A. E. (College of Aeronautics, Cranfield., 1982-10)
    The paper presents an experimental study of natural frequencies and modes of vibration of uniform cantilever plates. Sixteen planforms are tested by combining aspect ratios of 0.8, 1.2, 1.6 and 2 with leading edge sweep-back ...
  • Vibration of structures with non-linear damping 
    Gabri, B. S. (Cranfield University, 1978-03)
    The work reported here is directed towards the problem of measuring and modeling non-linear damping in steel space frame civil engineering structures. In order to gain a better understanding of the damping mechanism ...
  • Vibrations of a swept box 
    Radok, J. R. M. (College of Aeronautics, Cranfield, 1951-04)
    The equation of motion of a uniform swept box with stringers and ribs are deduced. For the case of vibrations of a cantilever they are transformed into integrated equations, an approximate method of solution of which is indicated.
  • Vibrations of the propeller shaft and the rear axle of a passenger car 
    Egbuson, A. K.; Hodgetts, D.; Hodgson, R. (College of Aeronautics, 19)
    Digital analysis of the free-free bending vibrations of a propeller shaft and a beam-type rear axle are compared, for different theoretical models, with the results of rig tests. The relative importance of distributed ...
  • Video re-sampling and content re-targeting for realistic driving incident simulation 
    Heras, Alejo M.; Breckon, Toby P.; Tirovic, Marko (2011-11-17)
    We present a video generation and visualization system for integration into a driving incident simulator. We combine the use of video re-sampling, target tracking and object segmentation for content re-targeting to ...
  • Videogrammetry: A practical method for measuring vegetation motion in wind demonstrated on wheat. 
    Hobbs, Stephen; Seynat, Cedric; Matakidis, Panos (Elsevier Science B.V., Amsterdam., 2007-02-10)
    Plant motion in wind is a common phenomenon but has rarely been quantified. Among other effects, plant motion is known to affect the quality (or “coherence”) of interferometric radar images although the loss of quality ...
  • Virtual testing of post-buckling behaviour of metallic stiffened panel 
    Wang, Yang (Cranfield University, 2011-12)
    The aim of the project presented in this thesis is to demonstrate a modelling method for predicting the variability in the ultimate load of stiffened panel under axial compression due to manufacturing variability. Bulking ...
  • Viscous flux limiters 
    Toro, E. F. (1991)
    We present Numerical Viscosity Functions, or NVFs, for use with Riemann-problem based shock-capturing methods as applied to viscous flows. In particular, viscous flux limiters are derived. The analysis pertain to a linear ...
  • Vision based experimental investigation of two-phase flow in a rising pipe 
    Fu, Shan; Yeung, Hoi (2003-04-28)
    Multiphase pipeline flow is very important to oil, gas and process industry. This is a class of problems where comprehensive simulations, although desirable on physical grounds, are not practical due to the large aspect ...
  • Vision based landmark detection for UAV navigation 
    Elliott, Alexander William (Cranfield University, 2012)
    The majority of Unmanned Aerial Vehicles (UAV) available today depend on Global Position Satellites (GPS) and inertial measurement units (IMU) for state estimation used in navigation and control. However with the increase ...
  • Vision-based Navigation Using Landmark Recognition for Unmanned Aerial Vehicles 
    Mannberg, Mikael (Cranfield University, 2014-08)
    This thesis describes a new approach for a vision-based positioning system for Un- manned Aerial Vehicles using a recognition method based on known, robust geo- graphic landmarks. Landmarks are used to calculate a position ...
  • Visit to America September 11th - September 25th, 1967 
    Smith, D. A. (College of Aeronautics, 1967-10)
  • Visit to America September 11th - September 25th, 1967 
    Smith, D. A. (College of Aeronautics, 1967-10)
  • Visual cueing for collision avoidance system 
    Li, Huiying (Cranfield University, 2012)
    The modern Traffic Alert and Collision Avoidance System (TCAS) used in airlines today is the TCAS II. It provides pilots with both Traffic Advisory (TA) and Resolution Advisory (RA) which in turn reduces the incidence of ...
  • Visual inspection reliability for composite aircraft structures 
    Cook, Lawrence (Cranfield University, 2009-10)
    This thesis presents a study of the effects of surface colour, surface finish and dent shape on the visual inspection reliability of 3D surface indentations common in shape to those produced by impact damage to carbon ...
  • Vortex tube performance data sheets 
    Westley, R. (College of Aeronautics, 1957-07)
    Experiments to determine the effect of various operating and design parameters on the performance of a vortex tube are described in College of Aeronautics Note No. 30. The present note gives additional performance data ...
  • Wake affected boundary layer flows within an embedded stage of a multi-stage axial compressor 
    Lee, D. Y. (2001-06)
    Boundary Layer Flows in turbomachines have been recognised to crucially influence the stability and performance of gas turbine components particularly the compressor since its function is to provide a pressure rise through ...
