  2. 16. Development of the mineralogical path for geometallurgical modeling of iron ores

    Author : Mehdi Parian; Antti Remes; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : The demands for more effective utilization of ore bodies and proper risk management in the mining industry have resulted in a new cross discipline called geometallurgy. Geometallurgy connects geological, mineral processing and subsequent downstream processing information together to provide a comprehensive model to be used in production planning and management.

  4. 17. Aspects of Wide-Area Damping Control Design using Dominant Path Synchrophasor Signals

    Author : Yuwa Chompoobutrgool; Luigi Vanfretti; Glauco Nery Taranto; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; power system stability and control; inter-area oscillations; wide-area damping control; synchrophasor measurements; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The presence of inter-area oscillations has long affected stability constraints, and therefore, limited the power transfer capacity of interconnected power systems. Adequate damping of these inter-area oscillations is, thus, necessary to secure system operation and ensure system reliability while increasing power transfers. READ MORE

  5. 18. Concepts for Power System Small Signal Stability Analysis and Feedback Control Design Considering Synchrophasor Measurements

    Author : Yuwa Chompoobutrgool; Luigi Vanfretti; Mats Larsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wide-area damping control; inter-area oscillations; power system stabilizers; PMU; Järnvägsgruppen - Elsystem; Järnvägsgruppen - Elsystem;

    Abstract : In the Nordic power network, the existence of poorly damped low-frequency inter-area oscillations (LFIOs) has long affected stability constraints, and thereby, limited power transfer capacity. Adequate damping of inter-area modes is, thus, necessary to secure system operation and ensure system reliability while increasing power transfers. READ MORE

  6. 19. Optimal Networking in Wirelessly Powered Sensor Networks

    Author : Rong Du; Carlo Fischione; Ming Xiao; Aylin Yener; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless energy transfer; network lifetime; energy beamforming; IoT; smart cities; sensor networks; scheduling; optimization; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Wireless sensor networks (WSNs) are nowadays widely used for the long-term monitoring of small or large regions, such as lakes, forests, cities, and industrial areas. The performance of a WSN typically consists of two aspects: i) the monitoring performance, e.g. READ MORE

  7. 20. Effect of Uncertainty of Rock Properties on Radionuclide Transport by Groundwater : Implications for Performance Assessments of the Repository of Spent Nuclear Fuel in Heterogeneous Bedrock

    Author : Shulan Xu; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Radionuclide migration; heterogeneous rock property; stochastic process spectral analysis; temporal moments; auto-covariance functions; sorption kinetics; performance assessment; Geovetenskap; Earth sciences; Geovetenskap; Sedimentology; sedimentologi;

    Abstract : The overall objective of the current study is to develop a quantitative understanding of the effects of spatial variability in physical and geochemical properties of crystalline rock on the migration of radionuclides along a single fracture in bedrock. A stochastic model was developed to describe the transport of solutes in fractured rock. READ MORE
