    Assessment of site investigation and tunnel contract cost

    Get PDF
    The thesis concerns the research into the development and application of empirical guidelines regarding the capability of site investigation to define uncertainty in ground conditions and hence to minimise contract cost. The data has been abstracted from the documents of contracts on the Northumbrian Water Authority's Tyneside Sewerage Scheme and, to allow cost comparisons to be made, a system of index-linking costs has been used, which removes their time-dependency. A simplified theoretical approach, based on probability theory and decision analysis, has been included to model the situation of decision under uncertainty and comparisons are subsequently made between this approach and the empirical results. Conclusions are reached regarding the possible reduction in risk, financial uncertainty, with increasing site investigation

    Scribable opaque coating for transparent plastic film tape is not affected by aging, vacuum, and moderate temperature extremes. It consists of titanium dioxide, a water-compatible acrylic polymer emulsion, and a detergent. The coating mixture is readily dispersed in water before it is dried

    Computer program provides steady state analysis for liquid propellant propulsion systems

    Quantum Hall-like effect on strips due to geometry

    Full text link
    In this Letter we present an exact calculation of the effective potential which appears on a helicoidal strip. This potential leads to the appearance of lcalized states at a distance \xi_0 from the central axis. The twist \omega of the strip plays the role of a magnetic field and is responsable for the appearance of these localized states and an effective transverse electric field thus this is reminiscent of the quantum Hall effect. At very low temperatures the twisted configuration of the strip may be stalilized by the electronic states.Comment: 3 page

    Effects of inlet treatment location and treatment cavity depth on compressor noise

    Get PDF
    The ability of acoustic liners to reduce compressor noise inside and in front of an inlet was studied. An axial flow research compressor and a specially designed inlet were used inside an anechoic chamber. Acoustic and performance data were obtained for a range of inlet treatment locations and cavity depths to determine their effects on inlet noise over a range of blade passing frequencies. The greatest noise reductions in front of the inlet were obtained with acoustic treatment located close to the compressor and backed with the deepest cavities tested. Inside the inlet the maximum noise level reductions were obtained in the area of the treatment regardless of treatment location. No appreciable losses in compressor performance were measured
