    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial process control; Networked control systems; Wireless network; Event-triggered control; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : To tackle the ever-growing demands on high-quality and cost-effective industrial production, recent developments in embedded sensing, wireless communication, and cloud computing offer great opportunities. Resource-aware reliable wireless communication and real-time control are needed to leverage these technologies. LÄS MER

  3. 2. Modelling, analysis and experimentation of a simple feedback scheme for error correction control

    Författare :Oscar Flärdh; Karl H. Johansson; Mikael Johansson; Bo Bernhardsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network Control; Error Correction; Multiple-Input Describing Function; Extremum Seeking Control; Sensor Network Experiments; Automatic control; Reglerteknik;

    Sammanfattning : Data networks are an important part in an increasing number of applications with real-time and reliability requirements. To meet these demands a variety of approaches have been proposed. Forward error correction, which adds redundancy to the communicated data, is one of them. LÄS MER

  4. 3. Ekonomisk styrning för förändring : en studie av ekonomiska styrinitiativ i hälso- och sjukvården

    Författare :Tomas Blomquist; Johann Packendorff; Rolf A. Lundin; Anders Söderholm; Lars Lindkvist; Torbjörn Stjernberg; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Management accounting and control; organisational change; management control initiatives; health care; organising processes; projectification; space; time; actor categories;

    Sammanfattning : Since the end of the 1980’s  Swedish county council managers has been preoccupied with planning and implementing organisational change in order to alleviate the financial problems and to create more efficient production systems. Many of these efforts to change have implied changing the systems for management accounting and control, changes that have been inspired both by market-oriented ideologies and by the governance principles of large corporations in the private sector.

  5. 4. Multistage gearboxes : vibration based quality control

    Författare :Johan Wändell; Hans Bodén; Ulf Carlsson; Kjell Ahlin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik;

    Sammanfattning : In this thesis, vibration based techniques for detection of localised surface damages in multistage gearboxes are presented and evaluated. A modern vehicle gearbox is a complex system and the number of potential errors is large. For instance, surface damages can be caused by rough handling during assembly. LÄS MER

  7. 5. Task-oriented control and coordination of multi-agent systems under varying constraints

    Författare :Pian Yu; Dimos V. Dimarogonas; Carlo Fischione; Christos Cassandras; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-agent systems; uncertain systems; temporal logics; event-triggered control; control synthesis; conflict resolution; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Multi-agent systems (MAS) offer a tremendous potential to improve the quality of modern society life. For instance, robot networks have been widely used for providing services such as search and rescue missions, surveillance and data collection, healthcare and entertainment. LÄS MER
