  • Deformation mechanisms beneath shallow foundations 

    McMahon, Brendan (University of CambridgeDepartment of Engineering, 2013-02-05)
    Shallow foundations can provide the most economical solution for supporting small-scale structures. The design approach is quite simple considering the ultimate bearing capacity and working-load settlement. Research has ...

  • Autoregressive models for statistical parametric speech synthesis 

    Shannon, Matt; Zen, Heiga; Byrne, William Joseph (IEEE (Institute of Electrical and Electronics Engineers), 2013-03)
    We propose using the autoregressive hidden Markov model (HMM) for speech synthesis. The autoregressive HMM uses the same model for parameter estimation and synthesis in a consistent way, in contrast to the standard approach ...

  • Turbulent partially premixed combustion: DNS analysis and RANS simulation 

    Ruan, S. (University of CambridgeDepartment of Engineering, 2013-03-12)
    Increasingly stringent regulation of pollutant emission has motivated the search for cleaner and more efficient combustion devices, which remain the primary means of power generation and propulsion for all kinds of ...

  • 'You can't just hit a button’: an ethnographic study of strategies to repurpose data from advanced clinical information systems for clinical process improvement 

    Morrison, Cecily Peregrine; Jones, Matthew Russell; Jones, R; Vuylsteke, A (BMC Medicine, 2013-04)
    Abstract Background Current policies encourage healthcare institutions to acquire clinical information systems (CIS) so that captured data can be used for secondary purposes, including clinical process improvement. Such ...

  • Analysis of amorphous indium-gallium-zinc-oxide thin-film transistor contact metal 

    Kiani, Ahmed; Hasko, David G; Milne, William Ireland; Flewitt, Andrew John (AIP Publishing LLCApplied Physics Letters, 2013-04-15)
    It is widely reported that threshold voltage and on-state current of amorphous indiumgallium- zinc-oxide bottom-gate thin-film transistors is strongly influenced by the choice of source/drain contact metal. Electrical ...

  • Gas-sensitive holographic sensors 

    Martínez Hurtado, Juan Leonardo (University of CambridgeDepartment of Chemical Engineering and BiotechnologyInstitute of Biotechnology, 2013-04-16)
    Holographic sensors are photonic layered structures contained in analyte sensitive lms that upon illumination produce monochromatic reflections (λ). The present work reports the fabrication of oxygen and ammonia sensors ...

  • 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 ...

  • Microwave-assisted pyrolysis of HDPE using an activated carbon bed 

    Russell, Alan Donald (University of CambridgeDepartment of Chemical Engineering and Biotechnology, 2013-04-16)
    Plastics play an enormous role in modern manufacturing, but the extraction and refining of raw materials, followed by the synthesis of plastics themselves, represents an enormous energy investment into a product that is ...

  • How do attitudes of habitual high-technology entrepreneurs to early-stage failure differ in Silicon Valley, Cambridge and Munich? 

    Cotterill, Keith (University of CambridgeDepartment of EngineeringInstitute for Manufacturing, 2013-04-16)
    Entrepreneurs develop new technology ventures in uncertain conditions with unproven technologies and limited resources. The majority of such ventures fail, yet entrepreneurship is regarded as a national (and regional) ...

  • Automatic induction of verb classes using clustering 

    Sun, Lin (University of CambridgeFaculty of Computer Science and TechnologyComputer Laboratory, 2013-04-30)
    Verb classifications have attracted a great deal of interest in both linguistics and natural language processing (NLP). They have proved useful for important tasks and applications, including e.g. computational lexicography, ...

  • 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 ...

  • Short and long-term genome stability analysis of prokaryotic genomes 

    Brilli, Matteo; Liò, Pietro; Lacroix, Vincent; Sagot, Marie-France (2013-05-08)
    Abstract Background Gene organization dynamics is actively studied because it provides useful evolutionary information, makes functional annotation easier and often enables to characterize pathogens. There is therefore a ...
