The new Coastal and Ocean Basin (COB) located at the Greenbridge Science Park in Ostend, Belgium is under construction since February 2017. The laboratory will provide a versatile facility that will make a wide range of physical modelling studies possible, including the ability to generate waves in combination with currents and wind at a wide range of model scales. The facility is serving the needs in Flanders, Belgium, in the fields of mainly offshore renewable energy and coastal engineering. The COB will allow users to conduct tests for coastal and offshore engineering research and commercial projects. The basin will have state-of-the-art generating and absorbing wavemakers, a current generation system, and a wind generator. It will be possible to generate waves and currents in the same, opposite and oblique directions. The basin is expected to be operational in 2019. This paper presents an overview of the basin’s capabilities, the ongoing work, and selected results from the design of the COB.

The last decade has seen the emergence and growth in this country, and elsewhere, of science parks. In 1984 the United Kingdom Science Park Association (UKSPA) was set up with eight founder members. The mushrooming that followed meant that by 1986 the Association could report 28 fully operated parks, seven others under construction and a number of Associate Members, of which Reading University was one.

Transmission Pipelines

The research described in this paper centers on a composite of thermoplastic materials that can be inserted in a degraded steel pipe to completely restore its strength. Through the use of fabrics consisting of ultra high strength fibers that are co-helically wrapped over a thin walled thermoplastic cylindrical tube that serves as a core, arbitrarily high pressures can be achieved. This paper first outlines the design, manufacturing and installation procedures developed for this unique material to provide a context for the engineering research. Based on this outline, the technological basis that has been developed for assuring the strength and long term durability of this concept during its insertion, and in its very long term service as a liner in energy transmission pipelines, is presented in detail. The research that is described includes burst testing of the material in stand alone pipe form, load/elongation testing of ultra high strength fabrics, and linear and nonlinear elastic and viscoelastic analysis models. This body of work indicates that the concept is fundamentally feasible for restoring a wide range of large diameter natural gas and liquid transmission pipelines to be able to carry arbitrarily high pressures over very long lifetimes. It also indicates that liners can be safely installed in long lengths even in lines with severe bends in a continuous manner. With further research the concept has the potential for eliminating hydro testing and smart pigging during service, and could possibly be installed in some lines that are currently unpiggable.

In our data-driven society, there are hundreds of possible data systems in the market with a wide range of configuration parameters, making it very hard for enterprises and users to choose the most suitable data systems. There is a lack of representative empirical evidence to help users make an informed decision. Using benchmark results is a widely adopted practice, but like there are several data systems, there are various benchmarks. This ongoing work presents an architecture and methods of a system that supports the recommendation of the most suitable data system for an application. We also illustrates how the recommendation would work in a fictitious scenario.

Asymmetric Flows

Prototype scale laboratory experiments have been conducted to investigate the sheetflow sediment transport of uniform sands under different skewed-asymmetric oscillatory flows. Experimental results reveal that in most of the case with fine sand, the “cancelling effect”, which balances the on-/off-shore net transport under pure asymmetric/skewed flows and results a moderate net transport, was developed for combined skewed-asymmetric flow. However, under some certain conditions (T > 5s) with coarse sands, the onshore sediment transport was enhanced by 50% under combined skewed-asymmetric flows. Sand transport mechanism under oscillatory sheetflow conditions is also studied by comparing the maximum bed shear stress and the phase lag parameter at each half cycle. A comparison of measurements including the new experimental data with a number of practical sand transport formulations shows that the Dong et al. (2013) formulation performs the best in predicting the measured net transport rates over a wide range of experimental conditions

Interest in astronomy has been significantly increased in Georgia. As a result, the development of astronomical research, education and public outreach are in progress. In Abastumani Astrophysical Observatory - a research institution at Ilia State University - the observational and theoretical studies comprise a wide range of topics in astronomy and adjacent fields: solar system bodies, solar physics, stellar and extragalactic astronomy, theoretical astrophysics, cosmology, atmospheric and near space physics. Georgian scientists are involved in wide international collaboration and participate in a number of networks and projects. Astronomical education at bachelor, master and doctoral levels are held at Ilia University. PhD programs are also offered at other universities. In 2018, under the financial support of the World Bank and Georgian government, the renovation of Abastumani Observatory has been started. International conferences and workshops have been carried out in Georgia. Excursions at the Observatory and public lectures in astronomy throughout the country are carried out. Amateur astronomers organize astronomical events. A private observatory is under construction near Tbilisi. All these puts better perspective for future development of astronomy in Georgia.

Multiple Configurations

AbstractMultiple configurations of synchronously rotating permanent magnet cylinders magnetized across the axes are proposed for liquid metal stirring for homogenization as well as for pumping. Universal analytical model is used for an initial parameter analysis. Then experimental setups were built to perform physical modelling of the industrial applications, e.g. large-scale metallurgical furnaces. Velocity distribution in the liquid metal was measured using different methods: the Ultrasound Doppler anemometry and the potential difference probes. The study shows that the cylindrical permanent magnet setups can achieve up to 10 times higher energy efficiency compared to AC inductors and have potential of wide-range industrial application, e.g. can be used as stirrers for secondary aluminium furnaces with up to 50 cm thick walls.

Rapidly expanding development is taking place in the Arctic and sub-Arctic seas of Alaska and Canada, driven by the discovery of immense resources of oil and gas and favorable geophysical conditions in adjoining areas. The Arctic regions are dominated by sea ice, from the central polar pack to the pressure ridges and rubble piles that form in the shear zone along the periphery. In the east, adjoining Labrador and Newfoundland, icebergs are encountered. Storm waves and surges during the summer, strong seismicity in certain areas, and weak and construction-difficult soils in many areas combine to make the design and construction of platforms abnormally difficult. Existing platforms for offshore exploration include sand and gravel islands in shallow-water areas, floating drillships accompanied by icebreakers, a concrete-caisson-retained island in the Canadian Beaufort Sea, and a converted VLCC, grounded on a prepared embankment and given additional protection by artificially constructed ice rubble. At the present time, two steel caissons, designed to be filled with sand after founding, and one floating drilling structure are under construction. In the design and planning stage are a number of new concepts for caissons, mostly constructed of prestressed lightweight concrete, designed to resist global forces in the range of 150 000 kips or more and local concentrated forces of 800 to 1000 psi over small areas. Prestressed lightweight concrete appears well suited to the demands of Arctic service. The towing, deployment, founding, and subsequent removal of exploratory platforms demands consideration of a wide variety of naval architectural aspects. One of the more critical areas facing designers is how to determine the forces and displacements caused by impact from a large ice floe or berg. The compliance of the structure and the hydrodynamic dissipation of kinetic energy need to be considered, as well as the crushing of the ice. The successful development of the Arctic demands consideration not only of a wide range of engineering and naval architectural aspects but also their integration with ecological, social, political and economic considerations.

Alex Cullen combined the sharpest of scientific minds with a gentle personality and a great sense of humour. He was Professor and Head of the Department of Electrical Engineering at Sheffield from 1955 to 1967, and then Head of the Department of Electrical Engineering at University College London (UCL) until 1980. He continued his research there as a Science and Engineering Research Council Senior Fellow until 1985, and for some years as Research Fellow of UCL. His research concerned electromagnetic waves over a wide range of microwave devices and measurement techniques, the latter at a fundamental level. These contributions were of a highly innovative and ‘ground-breaking’ nature. He was appointed OBE in 1960, and elected Fellow of the Royal Society in 1977. He was an accomplished jazz musician, playing drums and clarinet. He was a signatory of a letter to The Times in January 1986, calling on Prime Minister Margaret Thatcher to ‘Save British Science’. This led to the foundation of the Save British Science pressure group, now the Campaign for Science and Engineering (CaSE), which has built up an enviable reputation with politicians and the media in representing the concerns of scientists and engineers. When (now Sir) Eric Ash left UCL in 1985 to become Rector of Imperial College, he remarked that Alex was ‘the last gentleman in the business’.
