  1. 1. Improving interpretation by orthogonal variation Multivariate analysis of spectroscopic data

    University dissertation from Umeå : Kemiska institutionen, Umeå universitet

    Author : Hans Stenlund; Umeå universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; OPLS; PLS; Multivariate Analysis; Orthogonal variation; Chemometrics; hyperspectral images; FTIR; NIR; spectroscopy; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Abstract : 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. READ MORE

  2. 2. Multivariate Networks Visualization and Interaction Techniques

    University dissertation from Umeå : Kemiska institutionen, Umeå universitet

    Author : Ilir Jusufi; Linnéuniversitetet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Information Visualization; Multivariate Networks; Visual Analytics; Exploration; Interaction; Computer Science; Datavetenskap; Informations- och programvisualisering; Information and software visualization;

    Abstract : As more and more data is created each day, researchers from different science domains are trying to make sense of it. A lot of this data, for example our connections to friends on different social networking websites, can be modeled as graphs, where the nodes are actors and the edges are relationships between them.

  3. 3. Efficient Information Visualization of Multivariate and Time-Varying Data

    University dissertation from Institutionen för teknik och naturvetenskap

    Author : Jimmy Johansson; Linköpings universitet.; Linköpings universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Information visualization; parallel coordinates; interactive analysis; multivariate data; time-varying data; GPU; hardware graphics; TECHNOLOGY Information technology Computer science Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap Datalogi;

    Abstract : 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. READ MORE

  4. 4. Decoding the complex brain multivariate and multimodal analyses of neuroimaging data

    University dissertation from Umeå : Umeå University

    Author : Alireza Salami; Umeå universitet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multivariate analysis; univariate analysis; multimodal imaging; episodic memory; aging; functional magnetic resonance imaging; diffusion tensor imaging; biology; biologi; Psychology; psykologi; Computerized Image Analysis; datoriserad bildanalys;

    Abstract : Functional brain images are extraordinarily rich data sets that reveal distributed brain networks engaged in a wide variety of cognitive operations. It is a substantial challenge both to create models of cognition that mimic behavior and underlying cognitive processes and to choose a suitable analytic method to identify underlying brain networks.

  5. 5. Processing and analysis of NMR data Impurity determination and metabolic profiling

    University dissertation from Stockholm : Institutionen för analytisk kemi

    Author : Jenny Forshed; Stockholms universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantitative nuclear magnetic resonance spectrometry; qNMR; multivariate analysis; peak alignment; data fusion; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi;

    Abstract : This thesis describes the use of nuclear magnetic resonance (NMR) spectrometry as an analytical tool. The theory of NMR spectroscopy in general and quantitative NMR spectrometry (qNMR) in particular is described and the instrumental properties and parameter setups for qNMR measurements are discussed.
