  1. 21. Towards Active Car Body Suspension in Railway Vehicles

    Författare :Jessica Fagerlund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decoupling; Model reduction; Active suspension; MIMO systems; LQ control;

    Sammanfattning : Today, most railway suspension systems are passive. The most wide-spread exception isactive car body tilt systems, which are mounted in some high-speed trains. Replacingsome of the passive suspension components with active could reduce the weight and costof the vehicle. LÄS MER

  3. 22. Nonlinear observers with applications in the steel industry

    Författare :Andreas Johansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : Access to measurements is a necessity in most technical applications, in order to detect faults, monitor performance, or exercise control. In some cases, however, installing measurement equipment is very expensive or even impossible. In such a case, estimates can be produced instead. LÄS MER

  4. 23. On the Regulation of Ornithine Decarboxylase

    Författare :Eva Lövkvist Wallström; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysiologi; Physiology; Crithidia fasciculata.; polyamines; Ornithine decarboxylase; translational control; osmolarity; untranslated region; COS cells; CHO cells; transfection; protein turnover; PEST region;

    Sammanfattning : The polyamines putrescine, spermidine and spermine have been shown to be involved in cell growth and differentiation, and are considered to be crucial components of the living cell. The synthesis of polyamines in the cell is strictly regulated. LÄS MER

  5. 24. Characterization and Control of Multi-Cylinder Partially Premixed Combustion

    Författare :Magnus Lewander; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Efficiency estimation; Closed-loop control; EGR; Diesel engine; Partially Premixed Combustion; Combustion control;

    Sammanfattning : In the last decade diesel combustion has developed in a new direction. Research has been carried out trying to prolong the ignition delay and enhance fuel/air premixing to avoid diffusion combustion as well as lowering the combustion temperature through use of EGR. One of these new combustion concepts is Partially Premixed Combustion (PPC). LÄS MER

  7. 25. Modeling and Control of a PMSynRel Drive for a Plug-InHybrid Electric Vehicle

    Författare :Shuang Zhao; Chandur Sadarangani; Sigurd Övrebö; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric drive; feasible region; inductance spatial harmonics; integrated charger; permanent-magnet assisted synchronous reluctance machine; plug-in hybrid-electric vehicle; polarity detection; saturation and cross-saturation; sensorless control; signal injection; transient modeling.;

    Sammanfattning : This thesis presents two transient models for a prototype integrated charger for use in a plug-in hybrid-electrical vehicle application. The models can be useful in order to develop control algorithms for the system or to recommend improvements to the machine design. LÄS MER
