  2. 16. The Impact of Application and Architecture Properties on Real-Time Multiprocessor Scheduling

    Author : Jan Jonsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; real-time scheduling; multiprocessor architectures; architecture properties; application properties; performance evaluation; predictability;

    Abstract : Guaranteeing the temporal correctness of a real-time system is a very challenging problem since application and architecture properties may be hard to model accurately. For example, modern computer architectures are typically equipped with mechanisms, such as cache memories and instruction pipelines, whose behavior are by nature stochastic. READ MORE

  4. 17. Three Aspects of Real-Time Multiprocessor Scheduling: Timeliness, Fault Tolerance, Mixed Criticality

    Author : Risat Pathan; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mixed-Criticality Systems; Fault-Tolerant Scheduling; Fixed Priority; Real-Time Systems; Global Multiprocessor Scheduling; Time Redundancy; Sporadic Tasks;

    Abstract : The design of real-time systems faces two important challenges: incorporating more functions/services on existing hardware to make the system more attractive to the market, and deploying existing software on multiprocessors (e.g., multicore) to utilize moreprocessing power.

  5. 18. On Sensor-Controlled Robotized One-off Manufacturing

    Author : Per Cederberg; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; one-off manufacturing; arc welding; world model; real-time; task-oriented programming; simulation; control; robotics; sensor; Automation; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : A semi-automatic task oriented system structure has been developed and tested on an arc welding application. In normal industrial robot programming, the path is created and the process is based upon the decided path. Here a process-oriented method is proposed instead. READ MORE

  6. 19. Hydrobatics: Real-time Control, Simulation and Learning for Underactuated AUVs in Agile Maneuvers

    Author : Sriharsha Bhat; Ivan Stenius; Dimos V. Dimarogonas; Massimo Caccia; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; utonomous Underwater Vehicles; Underactuated Systems; Model Predictive Control; Hybrid Systems; Simulation; System Identification; Adaptive Sampling; Cyber-physical Systems.; Autonoma Undervattensfarkoster AUV ; Modellering; Simulering; Modelprediktiv kontroll MPC ; Systemidentifiering; Adaptiv mätning; Fältförsök; Cyber-fysikaliska System CPS .; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : The term hydrobatics refers to the agile maneuvering of underwater vehicles. Underwater robots such as autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs) are either designed as flight style, optimized for range and speed, or hover style, optimized for precise maneuverability.

  7. 20. Active Distributed Power Systems Functional Structures for Real-Time Operation of Sustainable Energy Systems

    Author : Jörgen Svensson; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; Distributed power systems; RES; Power electronics; Energy management system; Real-time operation; Advanced functions; Communication; Elektronik och elektroteknik; Electronics and Electrical technology; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : Present power system will face great challenges in several areas depending on the market economy, extensive global integration and constant need for more electric power, which will force the system to operate much closer to its stability limits. Meeting these challenges may involve improving and complementing or even total restructuring of the power systems. READ MORE
