  1. 21. Network-based Anomaly Detection for SCADA Systems : Traffic Generation and Modeling

    Författare :Chih-Yuan Lin; Simin Nadjm-Tehrani; Mikael Asplund; Aditya P. Mathur; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Supervisory Control and Data Acquisition (SCADA) systems control and monitor critical infrastructure in society, such as electricity transmission and distribution systems. Modern SCADA systems are increasingly adopting open standards and being connected to the Internet to enable remote control. LÄS MER

  3. 22. Experimental studies of turbulent flames at gas turbine relevant burners and operating conditions

    Författare :Xin Liu; Förbränningsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent Combustion; Gas Turbine; Laser diagnostic; Fuel flexibility; Plasma-assisted combustion; Ammonia flame; High pressure;

    Sammanfattning : With the increasing demand of using alternative and renewable fuels, it becomes of vital importance to consider the fuel flexibility when designing a new burner for gas turbines. Hydrogen-enriched fuel and ammonia are two of these potential fuels, and they can significantly change the operability range of the gas turbines. LÄS MER

  4. 23. Respiratory mechanics during mechanical ventilation in health and in disease

    Författare :Cecilia Svantesson; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Recruitment; Collapse; Overdistension; Viscoelasticity; Elastic pressure-volume curve; Respiratory disease; Health; Human; Rabbit; Positive end-expiratory pressure; Anaesthesiology; intensive care; Anestesiologi; intensivvård;

    Sammanfattning : The elastic pressure-volume (Pel-V) curve of the respiratory system can be used as a guide for improved ventilator management. It may indicate risks of lung damage associated with collapse or overdistension of lung units. LÄS MER

  5. 24. Integrated analyses and interpretations of regional scale magnetotelluric and potential field data from the Precambrian crust of northern Sweden

    Författare :Roshanak Vadoodi; Thorkild Maack Rasmussen; Maxim Smirnov; Björn H. Heincke; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Exploration Geophysics; Prospekteringsgeofysik;

    Sammanfattning : The Norrbotten region in northern Sweden, as a part of the Fennoscandian (Baltic) Shield, is one of the most active mining areas in Europe. It is acknowledged that geological structures such as faults, shear zones, and associated fracture systems play a key role in providing a physical pathway connecting metal sources and the sites of mineral precipitation.

  7. 25. Laser-Based Investigations of Combustion Phenomena in Gas Turbine Related Burners

    Författare :Arman Subash; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Combustion; Gas turbine; Chemiluminescence; laser-based techniques; LIF; PIV; DLE; TARS; CH4; H2; OH; CH20; Equivalence ratio; flame stabilization; LBO; Flashback; RPL; Fysicumarkivet A:2018:Subash;

    Sammanfattning : Experiments were performed on various combustion devices to investigate the flames employing different optical measurement techniques under atmospheric pressure conditions. Non-intrusive laser-based techniques provided in-situ information concerning different parameters of the combustion process, with a high degree of temporal and spatial resolution. LÄS MER
