  1. 1. Multivariate Exploration and Processing of Sensor Data-applications with multidimensional sensor systems

    Författare :Henrik Petersson; Martin Holmberg; Johan Trygg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical sensor; Pattern recognition; sensor selcection; Combustion monitoring; Vector Classification; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Sammanfattning : A sensor is a device that transforms a physical, chemical, or biological stimulus into a readable signal. The integral part that sensors make in modern technology is considerable and many are those trying to take the development of sensor technology further. LÄS MER

  2. 2. Sensor Systems for Bioprocess Monitoring

    Detta är en avhandling från Analytical Chemistry, Lund University

    Författare :Helena Lidén; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; on-line; pattern recognition; gas sensor array; electronic nose; monosaccharides; ethanol; biosensor; carbon paste electrode; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Two different detection methods for on-line monitoring of substrates and products in ethanol fermentations have been studied. Amperometric biosensors were developed for use as detectors in flow injection or liquid chromatographic (LC) systems. LÄS MER

  3. 3. Microfluidic Devices for Manipulation and Detection of Beads and Biomolecules

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mats Jönsson; Ulf Lindberg; Bertil Hök; Johan Nilsson; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; sensor; micro; dielectrophoresis; impedance; electrode; beads; cell; flow; bacteria; microfabrication; biosensor; electrocapture; microfluidic; planar; Lab on chip; µTAS; micro total analysis system; QCM; dispersion; field-flow fractionation; ITO; design; fabrication; Teknisk fysik;

    Sammanfattning : This thesis summarises work towards a Lab-on-Chip (LOC). The request for faster and more efficient chemical and biological analysis is the motivation behind the development of the LOC-concept.Microfluidic devices tend to become increasingly complex in order to include, e.g. LÄS MER

  4. 4. On Medium Access for Wireless Ad-hoc and Sensor Networks

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Arash Tahmasebi Toyserkani; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MAC; Transmission range; Interference range; Taffic Safety; Sensor Networks; TDMA; CSMA;

    Sammanfattning : The medium access control (MAC) is a sub-layer of the data link layer, thesecond layer of the open system interconnection (OSI) model. The MAC sub-layeris responsible for organizing the access to the shared channel and it is due tothis important responsibility that the performance of networks is substantiallyinfluenced by the MAC protocol.

  5. 5. Fluxes and Mixing Processes in the Marine Atmospheric Boundary Layer

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Erik Olof Nilsson; Anna Rutgersson; Harm Jonker; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Waves; Growing sea; Swell; Marine boundary layer; Air-sea interaction; Mixing; Momentum flux; Wind stress; Flux attenuation; Sensor separation; Large eddy simulation; Multiresolution analysis; Coupling; Wave model; Climate model; Wave age; Meteorology; Meteorologi;

    Sammanfattning : Atmospheric models are strongly dependent on the turbulent exchange of momentum, sensible heat and moisture (latent heat) at the surface. Oceans cover about 70% of the Earth’s surface and understanding the processes that control air-sea exchange is of great importance in order to predict weather and climate. LÄS MER
