  2. 16. 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

  4. 17. Mechanical properties of excavated sulfur rich soil stabilized with cement - A laboratory and field experiment

    Author : Alaleh Ziagharib; Christian Maurice; Josef Macsik; Qi Jia; Jan Laue; Bo Vesterberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sulfur-rich soil; Mixing; Sampling; Unconfined compressive strength; stabilization; Porosity; Water content; Consistency limits; Geoteknik; Soil Mechanics;

    Abstract : Sulfide soils are silty soils, often found in saturated conditions, under the groundwater level. Characteristics of these soils, including particle size distribution and consistency limits along with chemical composition and environmental properties, cause excavation to be necessary for construction purposes.

  5. 18. Modeling and simulation of intrinsically disordered proteins

    Author : Joao Henriques; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Intrinsically disordered proteins; Coarse-grained models; Atomistic models; Metropolis Monte Carlo simulations; Molecular dynamics simulations; Sampling; Conformational analysis; Charge regulation; Surface adsorption;

    Abstract : This work is primarily about the development, validation and application of computer simulation models for intrinsically disordered proteins, both in solution and in the presence of uniformly charged, ideal surfaces. The models in question are either coarse-grained or atomistic in nature, and their applications are dependent on the specific purpose of each study. READ MORE

  6. 19. Reliability-Based Assessment and Optimization of High-Speed Railway Bridges

    Author : Reza Allahvirdizadeh; Raid Karoumi; Andréas Andersson; Daniel Straub; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-speed railway bridges; Bridge dynamics; Running safety; Passenger comfort; Structural reliability; Meta-models; Surrogate models; Adaptive sampling; Reliability-based design optimization; Höghastighetsjärnvägsbroar; Brodynamik; Trafiksäkerhet; Passagerarkomfort; Konstruktioners tillförlitlighet; Metamodeller; Surrogatmodeller; Adaptiv sampling; Tillförlitlighetsbaserad designoptimering; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Abstract : Increasing the operational speed of trains has attracted a lot of interest in the last decades and has brought new challenges, especially in terms of infrastructure design methodology, as it may induce excessive vibrations. Such demands can damage bridges, which in turn increases maintenance costs, endangers the safety of passing trains and disrupts passenger comfort. READ MORE

  7. 20. Fiber-based all-optical sampling for ultrafast waveform monitoring

    Author : Mathias Westlund; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polarization independent; waveform monitoring; software synchronization; four-wave mixing; all-optical sampling;

    Abstract : Digital sampling is a technique to visualize a time-varying waveform by capturing quasi-instantaneous snapshots of a signal via a sampling gate. The gate is opened and closed by narrow pulses in a pulse train having a well defined repetitive behaviour such that all parts of the waveform are measured. READ MORE
