    Sammanfattning : In this work, various aspects of multivariate monitoring and control of wastewater treatment operation are discussed. A number of important difficulties face operators and process engineers when handling online measurements from wastewater treatment processes. LÄS MER

  4. 18. Improving the Performance of Gas Sensor Systems with Advanced Data Evaluation, Operation, and Calibration Methods

    Författare :Manuel Bastuck; Andreas Schütze; Mike Andersson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In order to facilitate the widespread use of gas sensors, some challenges must still be overcome. Many of those are related to the reliable quantification of ultra-low concentrations of specific compounds in a background of other gases. LÄS MER

  5. 19. Electrochemical (bio-)sensors operating in human physiological fluids

    Författare :Carolin Psotta; Sergey Shleev; Magnus Falk; Evgeny Katz; Malmö universitet; []
    Nyckelord :biosensor; bacteria; enzyme; sensor; physiological fluid;

    Sammanfattning : This thesis is focused on developing electrochemical (bio-)sensors specifically designed to detect biomolecules and bacteria in human physiological fluids. A more comprehensive understanding of their performance can be obtained by exposing the sensors to real human physiological fluids. LÄS MER

  7. 20. International Asset Pricing, Diversification and Links between National Stock Markets
