  3. 2. Instrumental and methodological developments for isotope dilution analysis of gaseous mercury species

    Författare :Tom Larsson; Erik Björn; Holger Hintelmann; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mercury; gas; species; speciation analysis; isotope dilution analysis; permeation tubes; Analytical chemistry; Analytisk kemi;

    Sammanfattning : This thesis deals with instrumental and methodological developments for speciation analysis of gaseous mercury (Hg(g)), based on isotope dilution analysis (IDA). The studied species include Hg0, (CH3)2Hg, CH3HgX and HgX2 (where X symbolises a negatively charged counter ion in the form of a halide or hydroxyl ion). LÄS MER

  5. 4. Improving interpretation by orthogonal variation : Multivariate analysis of spectroscopic data

    Författare :Hans Stenlund; Johan Trygg; Tom Fearn; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; OPLS; PLS; Multivariate Analysis; Orthogonal variation; Chemometrics; hyperspectral images; FTIR; NIR; spectroscopy; Chemistry; Kemi;

    Sammanfattning : The desire to use the tools and concepts of chemometrics when studying problems in the life sciences, especially biology and medicine, has prompted chemometricians to shift their focus away from their field‘s traditional emphasis on model predictivity and towards the more contemporary objective of optimizing information exchange via model interpretation. The complex data structures that are captured by modern advanced analytical instruments open up new possibilities for extracting information from complex data sets. LÄS MER

  7. 5. Analysis of Some Methods for Identifying Dynamic Errors-in-variables Systems

    Författare :Mei Hong; Torsten Söderström; Magnus Jansson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; errors-in-variables; least squares; instrumental variable; maximum likelihood; bias compensated least squares; bias eliminating least squares; Frisch scheme; higher-order statistics; accuracy analysis; periodic data; Signal processing; Signalbehandling;

    Sammanfattning : A system where errors or noises are present on both the inputs and the outputs is called an errors-in-variables (EIV) system. EIV systems appear in industrial and agricultural processes, medical sciences, economical systems, biotechnology, as well as in many other areas. LÄS MER
