  • Behaviour of GFRP adhesive pipe joints subjected to pressure and axial loadings 

    Lees, Janet Marillyn (ElsevierComposites Part A: Applied Science and Manufacturing, 2006)
    The corrosion resistance of glass-fibre reinforced polymers (GFRPs) is a key advantage in pipeline applications. Adhesive bonded joints are often used in tensile resistant GFRP pipe systems and the behaviour of small-diameter ...

  • Transmission capacity improvement for high speed multimode waveguide links using advanced optical launch and multilevel modulation schemes 

    Geng, Liang (University of CambridgeDepartment of Engineering, 2013-07-09)
    This dissertation investigates the potential technologies in both optical and electrical domains for transmission capacity improvement in multimode waveguide links. The first half of the dissertation focuses on the multimode ...

  • On the playability of stringed instruments 

    Galluzzo, Paul M. (University of CambridgeDepartment of EngineeringTrinity College, 2004-07-13)
    As first noticed by Helmholtz, strings vibrate in a “V-shape” when they are bowed correctly and a full tone is produced, where the vertex of the “V” shuttles back and forth along the visible envelope of the string’s motion. ...

  • Vortex flow around the bases of obstacles 

    Baker, Christopher James (University of CambridgeSt. Catharine's CollegeDepartment of Engineering, 1979-02-06)
    This thesis presents the results of experimental and theoretical investigations of the horseshoe vortex systems caused by boundary layer separation upstream of obstacles mounted on a wall. Flow visualization enabled these ...

  • Future, Opportunities and Challenges of Inkjet Technologies 

    Castrejon-Pita, J. R.; Baxter, W. R. S.; Morgan, J.; Temple, S.; Martin, G. D.; Hutchings, I. M. (2013-08-07)

  • Collaboration between designers and scientists in the context of scientific research 

    Peralta, Carlos (University of CambridgeDepartment of EngineeringInstitute for Manufacturing (IfM), 2013-10-08)
    Collaboration between Designers and Scientists in the Context of Scientific Research This thesis presents the results of a research project that examines collaboration between product designers and scientific researchers. ...

  • Automatic Transcription of Multi-genre Media Archives 

    Lanchantin, Pierre Kim; Bell, PJ; Gales, Mark John; Hain, T; Liu, X; Long, Y; Quinnell, J; Renals, S; Saz, O; Seigel, MS; Swietojanski, S; Woodland, Philip Charles (2013)
    This paper describes some recent results of our collaborative work on developing a speech recognition system for the automatic transcription or media archives from the British Broadcasting Corporation (BBC). The material ...

  • Mean reaction rate closures for nanoparticle formation in turbulent reacting flow 

    Akroyd, Jethro (University of CambridgeDepartment of Chemical Engineering and Biotechnology, 2012-11-08)
    This thesis investigates mean reaction rate closures for turbulent reacting flow. The closures model the mean rate of reaction in the flow and are applied to simulations of nanoparticle formation. The simulations couple ...

  • Understanding environmental performance variation in manufacturing companies 

    Bocken, Nancy Maria (EmeraldInternational Journal of Productivity and Performance Management, 2013)
    Sustainability is an area of increasing interest for industry and its stakeholders, and some companies now aspire to address sustainability issues (e.g. carbon emissions) at strategic and operational levels. As companies ...


  • Control for transient response of turbocharged engines 

    Cieslar, Dariusz (University of CambridgeDepartment of Engineering, 2013-07-09)
    The concepts of engine downsizing and down-speeding offer reductions in CO2 emissions from passenger cars. These reductions are achieved by reducing pumping and friction losses at part-load operation. Conventionally, rated ...

  • Technology acquisition: sourcing technology from industry partners 

    Ortiz-Gallardo, Victor Gerardo (University of CambridgeDepartment of EngineeringCentre for Technology Management, 2013-07-09)
    This thesis describes the conditions that influence technology acquisition when an industry partner is involved. The objective of this thesis is to contribute to the knowledge regarding the conditions that affect effective ...

  • Modelling the vibration of tyre sidewalls 

    Graham, W. R. (ElsevierJournal of Sound and Vibration, 2013)

  • Modelling of friction stir spot welding 

    Reilly, Aidan (University of CambridgeDepartment of EngineeringSidney Sussex CollegeTrinity Hall, 2013-07-09)
    Friction stir spot welding (FSSW) is a solid-state welding process which is especially useful for joining precipitation-hardened aluminium alloys that undergo adverse property changes during fusion welding. It also has ...

  • Response of piled buildings to the construction of deep excavations 

    Korff, Mandy (IOS PressUniversity of CambridgeDepartment of EngineeringJesus CollegeDeltares, 2013-04-30)
    Trends in the construction of deep excavations include deeper excavations situated closer to buildings. This research provides insight into mechanisms of soil-structure interaction for piled buildings adjacent to deep ...

  • Mechanics of biomimetic materials for tissue engineering of the intervertebral disc 

    Strange, Daniel Geoffrey Tyler (University of CambridgeDepartment of Engineering, 2013-04-16)
    Tissue engineering offers a paradigm shift in the treatment of back pain. Engineered intervertebral discs could replace degenerated tissue and overcome the limitations of current treatments that disrupt the biomechanics ...
