RRS Charles Darwin Cruise 119C Leg B, 13 Aug - 14 Sep 1999. White Zone (WhiZ) environmental survey: seabed survey of the deep waters to the north and west of Shetland
No full textThis cruise formed part of the continuing Atlantic Margin Environmental Survey (AMES). The objectives of the cruise were: a) to complete TOBI sidescan sonar survey of the “White Zone”, begun on RRS Charles Darwin cruise 119C Leg A; b) to carry out photographic surveys of the “White Zone” to ground truth the sidescan sonar imagery and provide an assessment of the seabed fauna; and c) to carry out seabed sampling to further ground truth the sidescan sonar imagery and generate samples for the future analysis of selected environmental parameters (hydrocarbons, elements, particle size). The cruise was undertaken in three phases: I) seabed photography and sampling of the southern “White Zone” area (Wyville Thomson Ridge and adjacent areas of the Faroe Bank Channel and Faroe-Shetland Channel) surveyed by TOBI during RRS Charles Darwin cruise 119C Leg A; II) TOBI survey of the central Faroe-Shetland Channel, Faroe Slope and an area north of Shetland; and III) seabed photography and sampling of the areas surveyed by TOBI during phase two. The survey encountered a very widevariety of seafloor environments, including areas of extremely dense gravel cover, areas of near complete cobble / rock / boulder cover, and a field of small barchan sand dunes on the floor (1,200m) of the Faroe Bank Channel. Two other notable TOBI features were also examined: 1. A new field of “Darwin Mounds”, in the northern Rockall Trough, with associated colonies of the coral Lophelia pertusa and populations of the xenophyophore Syringammina fragilissima. 2. Localised areas of complex seabed topography (mud diapirs), in the area north ofShetland
Use of edge detection filter for monitoring urban change
No full textObservations concerning the level and distribution of building damage after a destructive earthquake are of primary importance in the immediate aftermath for planning response efforts, and later on for better understanding the effect of shaking on buildings. After recent earthquakes (the 2003 Boumerdes and Bam events) and the 2004 Indian ocean tsunami, very high-resolution (VHR) satellite imagery (QuickBird and Ikonos II) proved to be a valuable source of spatial information. For damage detection, textural change indexes have proved to be a useful means of describing and detecting changes between a temporal sequence of ‘before’ and ‘after’ images (Adams, 2003). However, for conventional spectrally-based approaches (e.g. band difference/ratio, principal component analysis) there are several factors that can hinder the direct extraction of useful information from an image, such as illumination differences and variable geometry angles (elevation and azimuth of sun and satellite). This paper explores an object-oriented approach to the detection of buildings damage caused by the Bam earthquake, which minimizes these sources of error. It also introduces a novel “edge detection” approach to characterizing visible changes accompanying building collapse
MV Ocean Endeavour cruise 13 Oct-06 Nov 2005. Seabed environmental survey of Angola Blocks 18 and 31
No full textThis cruise was carried out on behalf of BP Angola and comprised a seabed environmentalsurvey of Angola Blocks 18 and 31 (bathyal SE Atlantic). Seabed sampling was undertaken byMegacorer to provide samples for macrobenthos, hydrocarbon, heavy metal and particle sizeanalysis. Seabed photography (still and video) was undertaken with the NOC WASP vehicle.Baited, time-lapse camera deployments were undertaken using the BP ROBIO system(Oceanlab, Aberdeen). The survey spanned water depths of 1300-2050m over the AngolanMargin and included studies in and around seabed pockmarks and salt diapirs. Someindications of fluid flow and chemosynthetic communities were encountered.Should you wish to consult or cite this report please contact the author directly (Brian Bett,[email protected], +44 (0)23 80596355)
The Effect Of Error Correcting Coding On Indoor Wireless Communications Systems In The 20 - 60 GHz Region
No full textAs a follow-up of the literature study ’An Overview Of Indoor Wireless Communications Systems In Ilie 20 - 60 GHz Region’, published by B.J. Bout jand W.A. Schouten in December 1992, a further study has been performed to investigate the effect of Forward Error Correcting Coding on Indoor Wireless Communications Systems. This has been done by calculating the average fade- and non-fade duration as a function of the frequency and the Signal To Noise ratio. These results are conveyed to a Bit Error Probability. After that, the same calculations are done for the same channel, but with Forward Error Correcting Coding.Electrical Engineering, Mathematics and Computer ScienceTelecommunicatie- en Verkeersbegeleidingssysteme
Transient energy growth modulation by temperature dependent transport properties in a stratified plane Poiseuille flow
No full textWe investigate the effect of temperature dependent thermal conductivity λ and isobaric specific heat c_P on the transient amplification of perturbations in a thermally stratified laminar plane Poiseuille flow. It is shown that for decreasing thermal conductivity the maximum transient energy growth is amplified with respect to the λ=1 case, while the opposite occurs for increasing λ. A reversed mechanism is induced by a variable c_p. Substantial maximum growth enhancement/suppression is found in the range of Prandtl numbers Pr which encompasses most fluids of practical interest. The relative growth modulation shows an optimum Pr under spanwise perturbations. For energy amplifying property distributions a speed-up of the transient to reach the maximum energy growth is observed at low Pr, while a slow-down is found at large Pr. The opposite is true when the property variations suppress the growth of perturbations
