  4. 3. Diffusion of Radionuclides in Bentonite Clay : Laboratory and in sity Studies

    Författare :Mats Jansson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bentonite; montmorillonite; cation; anion; diffusion; sorption; cobalt; caesium; strontium; iodide; pertechnetate; surface diffusion; in situ; Chemistry; Kemi;

    Sammanfattning : This thesis deals with the diffusion of ions in compactedbentonite clay. Laboratory experiments were performed toexamine in detail different processes that affect thediffusion. To demonstrate that the results obtained from thelaboratory investigations are valid under in situ conditions,two different kinds of in situ experiments were performed. LÄS MER

  5. 4. On performance analysis of subspace methods in system identification and sensor array processing

    Författare :Magnus Jansson; Bo Wahlberg; Mats Molander; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; subspace methods; system identification; state-space models; linear regression; sensor array processing; performance analysis; EM algorithm; minimum redundancy array;

    Sammanfattning : This thesis addresses the issue of performance analysis of subspace-based parameter estimation methods in two different applications, namely system identification and sensor array processing.  The objective is to study the quality of the estimated models as the amount of data increases, and to suggest improvements and give user guidelines.

  7. 5. Measurements for winter road maintenance

    Författare :Mats Riehm; Per-Erik Jansson; Eros Pasero; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; winter road maintenance; sensors; infrared thermometry; energy efficiency; road salt;

    Sammanfattning : Winter road maintenance activities are crucial for maintaining the accessibility and traffic safety of the road network at northerly latitudes during winter. Common winter road maintenance activities include snow ploughing and the use of anti-icing agents (e.g. road salt, NaCl). LÄS MER
