  1. 16. Multivariate processing and modelling of hyphenated metabolite data

    Författare :Pär Jonsson; Michael Sjöström; Royston Goodacre; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemometrics; Curve Resolution; GC MS; LC MS; Metabolomics; Metabonomics; Multivariate Analysis and Multivariate Curve Resolution.; Organic chemistry; Organisk kemi;

    Sammanfattning : One trend in the ‘omics’ sciences is the generation of increasing amounts of data, describing complex biological samples. To cope with this and facilitate progress towards reliable diagnostic tools, it is crucial to develop methods for extracting representative and predictive information. LÄS MER

  3. 17. Size determination of hyaluronan and multivariate analysis of amyloid prone proteins

    Sammanfattning : The work presented in this thesis considers multivariate process capability indices (MPCIs) with focus on confidence intervals and tests for MPCIs. It also includes a case study, where multivariate statistical analysis and MPCIs are applied to data from a thermal spraying process at Volvo Aero Corporation. LÄS MER

  5. 19. Multivariate Analysis of 2D-NMR Spectroscopy : Applications in wood science and metabolomics

    Författare :Tommy Öman; Mattias Hedenström; Bjart Frode Lutnaes; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 2D NMR; HSQC; cellulose; ligning; STOCSY; HSQC-STOCSY; crystallinity; biologisk kemi; biological chemistry;

    Sammanfattning : Wood is our most important renewable resource. We need better quality and quantity both according to the wood itself and the processes that are using wood as a raw material. Hence, the understanding of the chemical composition of the wood is of high importance. LÄS MER

  7. 20. Monotonic regression for large multivariate datasets

    Författare :Oleg Sysoev; Panos Pardalos; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; Statistik;

    Sammanfattning : Monotonic regression is a non-parametric statistical method that is designed especially for applications in which the expected value of a response variable increases or decreases in one or more explanatory variables. Such applications can be found in business, physics, biology, medicine, signal processing, and other areas. LÄS MER
