  1. 11. Towards Optimal Real-Time Automotive Emission Control

    Författare :Jonathan Lock; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic programming; optimal control methods; hybrid vehicles; three way catalyst modelling; Automotive emissions control;

    Sammanfattning : The legal bounds on both toxic and carbon dioxide emissions from automotive vehicles are continuously being lowered, forcing manufacturers to rely on increasingly advanced methods to reduce emissions and improve fuel efficiency. Though great strides have been made to date, there is still a large potential for continued improvement. LÄS MER

  3. 12. Tailoring native compilation of Java for real-time systems

    Författare :Anders Nilsson; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; systems; numerical analysis; Java; embedded systems; real-time; aspect-oriented; object-oriented; Computer science; compiler construction; control; Datalogi; numerisk analys; system; kontroll;

    Sammanfattning : Our everyday appliances ranging from toys to vehicles, as well as the equipment used to manufacture them, contain an increasing number of embedded computers. Embedded systems software often implement functionality that is crucial for the operation of the device, resulting in a variety of timing requirements and resource utilization constraints to be fulfilled.

  4. 13. Energy-Centric Scheduling for Real-Time Systems

    Författare :Flavius Gruian; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; numerisk analys; Datalogi; Computer science; numerical analysis; System-Level Synthesis; Variable Speed Processors; Dynamic Voltage Scaling; Real-Time Scheduling; Energy Efficient Systems; control; systems; system; kontroll;

    Sammanfattning : Energy consumption is today an important design issue for all kinds of digital systems, and essential for the battery operated ones. An important fraction of this energy is dissipated on the processors running the application software. To reduce this energy consumption, one may, for instance, lower the processor clock frequency and supply voltage. LÄS MER

  5. 14. Resource-Constrained Embedded Control and Computing Systems

    Författare :Dan Henriksson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; reglerteknik; kontroll; Automation; robotics; control engineering; Automatiska system; numerisk analys; system; Datalogi; control; numerical analysis; systems; Computer science; Server control; Simulation tools; Feedback scheduling; Real-time control systems; Resource constraints;

    Sammanfattning : This thesis deals with methods for handling resource constraints in embedded control systems and real-time computing systems. By dynamic feedback-based resource scheduling it is possible to achieve adaptability andincreased performance for these systems. LÄS MER

  7. 15. Real Time Drag Minimization

    Författare :Marianne Jacobsen; Ulf Ringertz; Anders Forsgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aeronautics; optimization; experimental verification; Vehicle engineering; Farkostteknik;

    Sammanfattning : This thesis focuses on the use of multiple redundant control surfaces to increase performance during flight. There is no clear-cut definition of performance. It may differ between applications, but here, the amount of drag for a given flight condition is used. LÄS MER
