  1. 6. Energy Consumption and Running Time for Trains : modelling of running resistance and driver behaviour based on full scale testing

    Författare :Piotr Lukaszewicz; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy consumption; Running time; running resistance; driver behaviour; freight; train; energy coasting method; aerodynamic drag; driver model; degree of coasting; slippage; wind; Energy saving; braking ratio; powering ratio; full scale testing; Vehicle engineering; Farkostteknik;

    Sammanfattning : The accuracy in determined energy consumption and runningtime of trains, by means of computer simulation, is dependent upon the various models used. This thesis aims at developing validated models of running resistance, train and of a generaldriver, all based on full scale testing. LÄS MER

  3. 7. Realising full-scale control in wastewater treatment systems using in situ nutrient sensors

    Författare :Pernille Ingildsen; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; robotteknik; Automatiska system; control engineering; Instrumentation; Wastewater treatment; Control; Full-scale plants; Control structures; Electronics and Electrical technology; Elektronik och elektroteknik; robotics; Automation; kontroll av utsläpp; pollution control; Miljöteknik; Environmental technology;

    Sammanfattning : Abstract A major change in paradigm is taking place in the operation of wastewater treatment plants as automatic process control is becoming feasible. This change is due to a number of different reasons, not least the development of online nutrient sensors, which measure the key parameters in the biological nutrient removal processes, i.e. LÄS MER

  4. 8. Waste rock content variations during gravity flow in sublevel caving : analysis of full-scale experiments and numerical simulations

    Författare :Peter Gustafsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Sammanfattning : När man lastar i en skivrasgruva så märker man ofta att gråbergshalten varierar på ett oregelbundet sätt. Denna variation är oönskad på grund av att den leder till gråbergsinblandning och malmförluster. LÄS MER

  5. 9. Full Scale Applications of Permanent Magnet Electromagnetic Energy Converters : From Nd2Fe14B to Ferrite

    Författare :Boel Ekergård; Mats Leijon; Ronan costello; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis presents research regarding a full scale linear ferrite permanent magnet generator, installed in a wave energy conversion system. The ferrite based magnetic circuit, supplementing the previous utilized Nd2Fe14B-magnet design, is designed with an electromagnetic numerical simulation tool, where the model is derived from Maxwell’s equations.
