  1. 1. Functions of Generalized Bounded Variation

    Author : Martin Lind; Viktor Kolyada; Peter Oswald; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bounded p-variation; generalized bounded variation; modulus of continuity; function spaces; embeddings; Matematik; Mathematics;

    Abstract : This thesis is devoted to the study of different generalizations of the classical conception of a function of bounded variation.First, we study the functions of bounded p-variation introduced by Wiener in 1924. We obtain estimates of the total p-variation (1.. READ MORE

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

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

  3. 3. Computer methods for voice analysis

    Author : Svante Granqvist; KTH; []
    Keywords : voice analysis; perceptual analysis; fundamental frequency; correlogram; aperiodicity; Fourier analysis; high-speed imaging; laryngoscopy; vocal fold vibration; voice accumulation.; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis consists of five articles and a summary. Thethesis deals with methods for measuring properties of thevoice. The methods are all computer-based, but utilisedifferent approaches for measuring different aspects of thevoice. Paper I introduces the Visual Sort and Rate (VSR) method forperceptual rating of voice quality. READ MORE

  4. 4. Teaching for the learning of additive part-whole relations : The power of variation and connections

    Author : Anna-Lena Ekdahl; Ulla Runesson Kempe; Hamsa Venkat; Camilla Björklund; Christiane Benz; Jönköping University; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; variation; variation theory; connections in teaching; making connections; early numbers; teaching and learning additive relations; part-whole relation; part-whole relations of numbers; intervention study;

    Abstract : In this thesis, results from four empirical studies and a re-analysis are synthesized with what can constitute a structural approach to teaching and learning additive part-whole relations among learners aged four to eight years. In line with a structural approach to additive relations, the relations of parts and whole are in focus from the outset and are seen as the basis for addition and subtraction (Davydov 1982; Neuman, 1987).

  5. 5. Metabolic variation in autoimmune diseases

    Author : Rasmus Kirkegaard Madsen; Johan Trygg; Thomas Moritz; Torbjörn Lundstedt; Matej Oresic; Umeå universitet; []
    Keywords : Rheumatoid Arthritis; Diabetes Mellitus type 1; Metabolic Profiling; Metabolomics; Chemometrics; Multivariate Data Analysis; Mass Spectrometry; biologisk kemi; biological chemistry;

    Abstract : The human being and other animals contain immensely complex biochemical processes that govern their function on a cellular level. It is estimated that several thousand small molecules (metabolites) are produced by various biochemical pathways in humans. READ MORE
