  2. 1. Architectures for application transparent proxies : A study of network enhancing software

    Author : Björn Knutsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Communication; Proxies; Internet; Information technology; Informationsteknik; Computer Systems; Datorteknik;

    Abstract : Proxies, software deployed inside the network, play a fundamental role in the Internet by providing enhanced functionality to the network. Deployment of proxies is a flexible way of extending the Internet architecture with new services and to cope with problems that were not foreseen at the time the original Internet protocols were defined.

  4. 2. Bringing predictability into a geometallurgical program : An iron ore case study

    Author : Viktor Lishchuk; Bertil Pålsson; Cecilia Lund; Pertti Lamberg; Jennifer Broadhurst; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additivity; Apatite iron ore; AIO; Block model; Change of support; Classification; Data integration; DT; Feed quality; Geometallurgical program; Geometallurgy; Iron ore; Iron recovery; Leveäniemi; Liberation; Machine learning; Magnetic separation; Malmberget; Mineralogical approach; Mineralogy; Prediction; Proxies; Proxies approach; Sampling; Simulation; Synthetic ore body; Traditional approach; WLIMS; Mineral Processing; Mineralteknik;

    Abstract : The risks of starting, operating and closing mining projects have become higher than ever. In order to stay ahead of the competition, mining companies have to manage various risks: technical, environmental, legal, regulatory, political, cyber, financial and social. Some of these can be mitigated with the help of geometallurgy. READ MORE

  5. 3. Tree Rings as Sensitive Proxies of Past Climate Change

    Author : Håkan Grudd; Wibjörn Karlén; Brian Luckman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tree ring; width; density; climate; temperature; change; variability; sensitivity; Torneträsk; Tornetrask; Sweden; Fennoscandia; explosive; volcanic; eruption; Santorini; Thera; subfossil; Fitzroya; Chile; Physical geography; Naturgeografi;

    Abstract : In the boreal forests of the Northern Hemisphere, time series of tree-ring width (TRW) and maximum density in the latewood (MXD) are highly correlated to local instrumental summer-temperature data and are thus widely used as proxies in high-resolution climate reconstructions. Hence, much of our present knowledge about climatic variability in the last millennium is based on tree-rings. READ MORE

  6. 4. Marine oolites as proxies for palaeoenvironmental reconstructions during extinction events

    Author : Ingrid Urban; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ooids; Permian-Triassic boundary; Triassic-Jurassic Boundary; Arabian Platform; Southern Alps; palaeoenvironmental reconstruction;

    Abstract : At present time, it has been stated that “Human activities, principally through emissions of greenhouse gases, have unequivocally caused global warming, with global surface temperature reaching 1.1°C above 1850–1900 in 2011–2020”. READ MORE

  7. 5. Transport by Benthic Macrofauna: Functional Classification and Biogeochemical Response

    Author : Stina Lindqvist; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Marine sediments; Early diagenesis; Bioturbation; Functional groups; Benthic fluxes; Imaging; Ecosystem function; Sediment reworking; Transport proxies; Fluorescent particles;

    Abstract : Burrowing and reworking activities by benthic macrofauna regulate rates and pathways during organic matter mineralisation in bioturbated sediments. In so doing, they also affect the overall cycling of elements crucial in the biosphere (e.g. C, N, P, Fe, Mn and S). READ MORE
