  2. 26. The in-vitro and in-vivo metabolism of the oral anticoagulant phenprocoumon as influenced by genetic polymorphisms of cytochrome P4502C9

    Author : Mike Ufer; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Drug metabolism; cytochrome P450; genetic polymorphism; genotyping; CYP2C9; phenprocoumon; warfarin; acenocoumarol; oral anticoagulants;

    Abstract : Oral anticoagulants are widely used for the prevention of thromboembolic disorders. Warfarin (WA) is most commonly used world-wide, while phenprocoumon (PPC) is the first-line anticoagulant in some European countries including Germany. Each anticoagulant exists in two different enantiomeric forms and is administered orally as a racemate. READ MORE

  4. 27. Trajectory Tracking and Prediction-Based Coordination of Underactuated Unmanned Vehicles

    Author : Dzenan Lapandic; Bo Wahlberg; Antonio Pedro Aguiar; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In this thesis, we study trajectory tracking and prediction-based control of underactuated unmanned aerial and surface vehicles.  In the first part of the thesis, we examine the trajectory tracking using prescribed performance control (PPC) assuming that the model parameters are unknown.

  5. 28. Funnel-Based Control for Coupled Spatiotemporal Specifications

    Author : Farhad Mehdifar; Dimos V. Dimarogonas; Charalampos P. Bechlioulis; Bayu Jayawardhana; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Funnel-Based Control; Prescribed Performance Control; Uncertain Nonlinear Systems; Time-Varying Output Constraints; Coupled Spatiotemporal Constraints; Formation Control; Multi-Agent Systems; Trattbaserad kontroll; föreskriven prestandakontroll; osäkra icke-linjära system; tidsvarierande utgångsbegränsningar; kopplade rumsliga begränsningar; formationskontroll; multiagentsystem; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In the past decade, the integration of spatiotemporal constraints into control systems has emerged as a crucial necessity, driven by the demand for enhanced performance, guaranteed safety, and the execution of complex tasks. Spatiotemporal constraints involve criteria that are dependent on both space and time, which can be represented by time-varying constraints in nonlinear control systems. READ MORE

  6. 29. A numerical study of mixing phenomena and reaction front propagation in partially premixed combustion engines

    Author : Christian Ibron; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD simulation; förbränning; antändning;

    Abstract : This work treats the modelling of PPC engine combustion through 3D computational fluid dynamics. In order to develop a cost-effective CFD model for the design and performance analysis of PPC engines it is important to first understand the multiple modes of combustion in PPC engines, e.g. READ MORE

  7. 30. Physical Modeling and Control of Low Temperature Combustion in Engines

    Author : Anders Widd; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The topic of this thesis is model-based control of two combustion engine concepts, Homogeneous Charge Compression Ignition (HCCI) and Partially Premixed Combustion (PPC), using physics-based models. The studied combustion concepts hold promise of reducing the emission levels and fuel consumption of internal combustion engines. READ MORE
