  2. 1. On a mathematical basis for constitutive drivers in soil plasticity

    Author : Hans Mattsson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : Huvudsyftet med denna avhandling har varit att vidareutveckla en matematisk grund för konstitutiva drivenheter inom området plasticitetsteori för jord. Med en konstitutiv drivenhet avses här en datorrutin som innehåller ett antal utvalda konstitutiva modeller jämte integrationsmetoder och med vilken olika laboratorieförsök och fältförsök kan simuleras numeriskt och modellparametrar bestämmas genom optimering.

  4. 2. Integrated Bridge Maintenance : Evaluation of a pilot project and future perspectives

    Author : Hans-Åke Mattsson; Håkan Sundquist; Jan Bröchner; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bridge management; bridge maintenance; real service life; partnering; Building engineering; Byggnadsteknik;

    Abstract : The trend in many countries is to outsource maintenance with competitive tendering. The design of the tender is then a crucial issue. A new type of tendering contract, called "Integrated Bridge Maintenance", was introduced in one experimental area in Sweden. READ MORE

  5. 3. Design, Fabrication and Optimization of Thermal Radiation Detectors Based on Thin Polymer Membranes

    Author : Claes Mattsson; Hans-Erik Nilsson; Göran Thungström; Ylva Bäcklund; Mittuniversitetet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal detector; Polymer; Membrane; SU-8; Electronics; Elektronik;

    Abstract : The number of applications in which infrared radiation sensors are used is increasing. In some applications, the cost of the sensor itself is an issue, and simple solutions are thus required. In this thesis, the investigations have related to the use of thin polymer membranes in thermal infrared sensors, such as bolometers and thermopiles. READ MORE

  6. 4. Fabrication and Characterization of Photon Radiation Detectors

    Author : Claes Mattsson; Hans-Erik Nilsson; Göran Thungström; Mikael Lindeberg; Mittuniversitetet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Detectors; Posistion Sensitive Detectors; Electronics; Elektronik;

    Abstract : This thesis involves a study the fabrication and characterization of photon radiation detectors. The focus has been to develop and improve the performance of optical measurement systems, but also to reduce their cost. The work is based on the study of two types of detectors, the position sensitive detector and the thermal detector. READ MORE
