  1. 31. On physical units in multivariate analysis

    Författare :Tord Rikte; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : comparatively stringent mathematical frame has been developed, where the behaviour of physical dimensions (like ``length'', ``mass'', and ``time'') and physical units (like 1 m [1 metre], 1 kg [1 kilogramme], and 1 s [1 second]) is modelled. Easy-to-apply conditions for additivity and multiplicativity of physcial matrices are presented. LÄS MER

  4. 33. Multivariate integration and visualization of multiblock data in chemical and biological applications

    Författare :Tomas Skotare; Johan Trygg; David Nilsson; Alberto Ferrer; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multivariate analysis; PCA; PLS; OnPLS; JUMBA; Multiblock; calibration transfer;

    Sammanfattning : Thanks to improvements in technology more data than ever before is generated in almost all fields of science and industry.The data is analyzed to hopefully provide valuable information and knowledge about a product or process, such as how to improve the quality of a manufactured product.

  5. 34. Efficient Information Visualization of Multivariate and Time-Varying Data

    Författare :Jimmy Johansson; Mikael Jern; Matthew Cooper; Helwig Hauser; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information visualization; parallel coordinates; interactive analysis; multivariate data; time-varying data; GPU; hardware graphics; Computer science; Datalogi;

    Sammanfattning : Data can be found everywhere, for example in the form of price, size, weight and colour of all products sold by a company, or as time series of daily observations of temperature, precipitation, wind and visibility from thousands of stations. Due to their size and complexity it is intrinsically hard to form a global overview and understanding of them. LÄS MER

  7. 35. Applications of chemometrics in the analysis and characterization of lipids

    Författare :Peter Kaufmann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lipids; analysis; Lipider;

    Sammanfattning : The main topics of this thesis are the analysis and characterizationof lipids and applications of chemometrics in this field.The techniques of experimental design, polynomial model building,response surface methods, principal components analysis and partialleast squares regression have been explored and utilized in thedeveopment and optimization of analytical methods.
