  1. 1. Change detection in metal oxide gas sensor signals for open sampling systems

    Författare :Sepideh Pashami; Achim Lilienthal; Marco Trincavelli; Giorgio Sberveglieri; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal oxide sensors; Open Sampling System; change point detection; gas dispersion simulation; environmental monitoring; Computer Science; Datavetenskap;

    Sammanfattning : This thesis addresses the problem of detecting changes in the activity of a distant gas source from the response of an array of metal oxide (MOX) gas sensors deployed in an Open Sampling System (OSS). Changes can occur due to gas source activity such as a sudden alteration in concentration or due to exposure to a different compound. LÄS MER

  3. 2. Optimizing sampling of important events in complex biomolecular systems

    Författare :Lindahl Viveca; Berk Hess; Erik Lindahl; Bert de Groot; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics; free energy calculation; adaptive sampling; extended ensembles; membrane proteins; DNA; Biological Physics; Biologisk fysik;

    Sammanfattning : Proteins and DNA are large, complex molecules that carry out biological functions essential to all life. Their successful operation relies on adopting specific structures, stabilized by intra-molecular interactions between atoms. LÄS MER

  4. 3. Flexible Embedded Control Systems : Design and Implementation

    Författare :Johan Eker; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; Feedback scheduling; Quality of service; Linear quadratic control; Toolbox; Simulation; Rapid prototyping; Programming language; Scheduling; Embedded systems; Real-time system; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Embedded control system design is a complex and error prone task, and there is a great need for better development tools. Today most real-time control systems are static systems, designed in an ad-hoc fashion. A more interactive way of working would give shorter development times, reduced costs for testing, and safer, more robust systems. LÄS MER

  5. 4. Energy-Efficient Data Converters for Low-Power Sensors

    Författare :Kairang Chen; Atila Alvandpour; Ana Rusu; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Wireless sensor networks (WSNs) are employed in many applications, such as for monitoring bio-potential signals and environmental information. These applications require high-resolution (> 12-bit) analog-to-digital converters (ADCs) at low-sampling rates (several kS/s). LÄS MER

  7. 5. Service Life Assessment of Harbor Structures - Case studies of chloride ingress into concrete and sheet piling corrosion rates

    Författare :Henrik Wall; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chloride ingress; sampling methods; corrosion rates; sheet piling; ultra-sonic measurements; service life; durability; quay structures; harbor structures;

    Sammanfattning : The two most used building materials in harbor structures are undoubtedly steel and concrete. These two materials are often combined in the structures of wharfs and quays where the steel sheet pile walls often have cap beams of reinforced concrete. LÄS MER
