  • Power conversion systems for Ducks 

    Salter, Stephen Hugh (IEE 'Future Energy Concepts' Conference, 1979-01-30)
    This paper tries to define the problems of power conversion for a wave power device . It presents a little of the background theory; it discusses design principles, existing components and modifications to them; it tries ...
  • Power from sea waves 

    Salter, Stephen Hugh; 1 (The University of Edinburgh, 1974-03)
    There are people, until recently regarded as eccentric, who question our practice of treating as income those resources which our descendants will regard as capital. That apart, there are difficulties in satisfying ...
  • Solo Duck Mooring Forces 

    Woodhead, Peter Linnet (The University of Edinburgh, 1993-03-12)
    One of the major difficulties in the design of a wave energy device is the occasional occurrence of severe conditions at sea. The largest waves far exceed typical amplitudes over the year. Although it would be possible ...
  • Preliminary report on the use of tunnels for power transmission 

    Berry, N.S.M. (The University of Edinburgh, 1979-10-15)
    The potential for power generation from wave action increases with the distance off shore and the initial study has suggested that a location some 15 kilometres to the west of Uist would be attractive. The transmission ...
  • Bending moments of short spines 

    Retzler, Chris-Heinz; Salter, Stephen Hugh (1984-09-05)
    The Lanchester Polytechnic's 'Clam' wave energy device consists of a series of flexible air bags driving self-rectifying turbo-generators, mounted on an unjointed spine. The device is designed to be moored at about 35 ...
  • EWPP - SCOPA - Laing, 5th year report, Volume 2, Appendix 

    Salter, Stephen Hugh; Williams, Peter B. (The University of Edinburgh, 1979-11)
    1. Mechanical Design Philosophy and Calculations 2. Civil Design Philosophy and Calculations 3. Alternative Beaks 4. Lists of Drawings 5. Contributing Manufacturers with their comments 6. Reliability Considerations 7. ...
  • Parrots and monkeys 

    Jeffery, David Crighton (The University of Edinburgh, 1982)
    Before this series of experiments, Narrow Tank Duck control strategy had been researched by varying damping and spring in the three modes, nod, heave and surge. The justification for using this simple system was that ...
  • Edinburgh wave energy device moorings 

    Bullas, Michael (The University of Edinburgh, 1980-01)
    These notes are intended to bring together the various aspects of mooring of the Edinburgh Device known at the present time. Model tests indicate that the mooring forces for the device are substantially below those of other ...
  • EWPP - SCOPA - Laing, 5th year report, Volume 2, Drawings 

    Salter, Stephen Hugh; Williams, Peter B. (The University of Edinburgh, 1979-11)
    Engineering drawings of the Edinburgh Duck, consisting of: Artists Impression, G.A. of 10m Duck (25m wide), G.A. Flywheel Assembly, G.A. Spine Joint, Schematic of Power Cable Take-Up, Ring Cam Pump Assembly, Plan View Ring ...
  • Some Numerical Results for the Flat and Tall Floats 

    Pizer, David (The University of Edinburgh, 1994-08-26)
    Graphs are given for the added mass matrix, damping matrix and excitation force vector for the two floats discussed at the Hanstholm meeting. The flat float has a diameter of 6m, a height of 1.5m and is half submerged, ...
  • Comparing wave power from a Northern and a Southern site 

    Stoaling, P.M. (The University of Edinburgh, 1978)
    Instantaneous wave power at a single site varies considerably with time. Combining the power outputs from two distant sites could be a way of reducing the variation in instantaneous power output. Wave data from Boyle, ...
  • Exploring the role of the Phosphatidylinositol-3'-Kinase (PI3K) pathway in primordial follicle activation and subsequent development 

    Spence, Susan Claire (The University of Edinburgh, 2016-11-29)
    Mammalian females form their germ cells (oocytes) before or shortly after birth. The oocytes interact with somatic cells to form primordial follicles, creating the quiescent population from which oocytes will be recruited ...
  • Design and implementation of transgenic tools to visualise cell cycle progression in mammalian development 

    Ford, Matthew Jonathan (The University of Edinburgh, 2017-07-08)
    Cell cycle progression is the series of steps a cell has to take in order to duplicate its DNA and produce two daughter cells. Correct spatial and temporal coordination of the cell cycle is key for the normal development ...
  • Critical account of ideology in consumer culture: the commodification of a social movement 

    Rome, Alexandra Serra (The University of Edinburgh, 2017-07-10)
    The study of ideology has long interested sociologists and consumer researchers alike. Much consumption research has approached ideology from various macro, meso, and micro levels of analysis. However, many studies fail ...
  • Immunomodulatory proteins in Heligmosomoides polygyrus excretory/secretory products 

    Kemter, Andrea Maria (The University of Edinburgh, 2016-11-29)
    Infections with parasitic helminths are counted as neglected tropical diseases; they infect millions of people worldwide, causing high morbidity and economic loss. Many parasites establish long lasting infections in the ...
  • Synthesis of novel polymers of intrinsic microporosity for potential application as gas separation membranes 

    Karim Karim, Sadiq Abdul-Hussain (The University of Edinburgh, 2016-11-29)
    The work reported in this thesis describes the successful preparation of three classes of polymer that were designed to possess intrinisic microporosity from a range of aromatic tetrahydroxy and diamine monomers. The ...
  • Power of the informal: smallholder charcoal production in Mozambique 

    Jones, Daniel Edward (The University of Edinburgh, 2017-07-03)
    The charcoal market in Africa is an informal economy. This enables millions of people to earn a living producing, selling and trading charcoal, due to low barriers to market entry. However, research and policy on charcoal ...
  • Earthquake distributions at volcanoes: models and field observations 

    Roberts, Nick Stuart (The University of Edinburgh, 2016-11-28)
