  1. 1. Compensating for Unreliable Communication Links in Networked Control Systems

    Författare :Erik Henriksson; Karl Henrik Johansson; Henrik Sandberg; Bruno Sinopoli; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; packet loss compensation; unreliable communication; control over wirless networks; Automatic control; Reglerteknik;

    Sammanfattning : Control systems utilizing wireless sensor and actuator networks can be severely affectedby the properties of the communication links. Radio fading and interferencemay cause communication losses and outages in situations when the radio environmentis noisy and low transmission power is desirable. LÄS MER

  3. 2. Predictive Control for Wireless Networked Systems in Process Industry

    Författare :Erik Henriksson; Karl H. Johansson; Henrik Sandberg; Tore Hägglund; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model predictive control; networked control systems; wireless systems; process industry; automatic control;

    Sammanfattning : Wireless networks in industrial process control enable new system architectures and designs. However, wireless control systems can be severely affected by the imperfections of the communication links. LÄS MER

  4. 3. Experimental studies in brain tumours : with special regard to multidrug resistance and the ErbB-family

    Författare :Ulrika Andersson; Roger Henriksson; Beatrice Malmer; Erik Blomquist; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; glioma; meningioma; endothelium; MDR; Pgp; MRP1; LRP; MGMT; EGFR; ErbB2; ErbB3; ErbB4; Onkologi; Oncology; Onkologi; onkologi; Oncology;

    Sammanfattning : Primary brain tumours, and especially the most common form malignant gliomas, usually display a pronounced resistance to other treatment modalities when surgery fails to cure. Growth factors, such as EGF and its receptor, frequently amplified and overexpressed in malignant gliomas, and factors associated with multidrug resistance have been suggested to at least partially explain the poor outcome.

  5. 4. Diagnosis and Supervision of Industrial Gas Turbines

    Författare :Emil Larsson; Jan Åslund; Erik Frisk; Lars Eriksson; Mattias Henriksson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Monitoring of industrial gas turbines is of vital importance, since it gives valuable information for the customer about maintenance, performance, and process health. The performance of an industrial gas turbine degrades gradually due to factors such as environment air pollution, fuel content, and ageing to mention some of the degradation factors. LÄS MER

  7. 5. Enabling Technologies for Management of Distributed Computing Infrastructures

    Författare :Daniel Espling; Erik Elmroth; Rizos Sakellariou; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; grid computing; cloud computing; accounting; billing; contextualization; monitoring; structure; fairshare; scheduling; federated; Computer Science; datalogi;

    Sammanfattning : Computing infrastructures offer remote access to computing power that can be employed, e.g., to solve complex mathematical problems or to host computational services that need to be online and accessible at all times. LÄS MER
