2. 1. Deciphering sequence data : A multivariate approach

   Author : Maria Sandberg Hiltunen; Michael Sjöström; Svante Wold; Lars Ståhle; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Principal properties; amino acids; nucleotides; tRNA; DNA; multivariate data analysis; sequence analysis; QSAR; quantitative sequence activity relationships;

   Abstract : In this thesis, attention has been focused on the quantitative description of nucleic acids, proteins and peptides. The strategy was to use multivariate chemometrical methods for improving the understanding of the complex structural codes of these kinds of biological molecules. READ MORE

4. 2. Linear and Non-linear Deformations of Stochastic Processes

   Author : Gustaf Strandell; Maciej Klimek; Richard Aron; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; Riesz bases and frames; Weakly stationary stochastic processes; Set-valued analysis; Matematisk analys; Mathematical analysis; Analys;

   Abstract : This thesis consists of three papers on the following topics in functional analysis and probability theory: Riesz bases and frames, weakly stationary stochastic processes and analysis of set-valued stochastic processes. In the first paper we investigate Uniformly Bounded Linearly Stationary stochastic processes from the point of view of the theory of Riesz bases. READ MORE

5. 3. The Symmetric Meixner-Pollaczek polynomials

   Author : Tsehaye Araaya; Sten Kaijser; Svante Janson; Hjalmar Rosengren; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; Meixner-Pollaczek polynomial; Orthogonal polynomial; Polynomial operator; Inner product; Umbral calculus; Sheffer polynomial; Convolution type polynomial; Connection and linearization problem; 33C45; 05A40; 33D45; Matematisk analys; Mathematical analysis; Analys; matematik; Mathematics;

   Abstract : The Symmetric Meixner-Pollaczek polynomials are considered. We denote these polynomials in this thesis by pn(λ)(x) instead of the standard notation pn(λ) (x/2, π/2), where λ > 0. READ MORE

6. 4. Image Reconstruction and Optical Flow Estimation on Image Sequences with Differently Exposed Frames

   Author : Tomas Bengtsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple camera settings; human visual system; super-resolution; optical flow; high dynamic range; digital camera system; image reconstruction; motion analysis; inverse problem;

   Abstract : The main objective for digital image- and video camera systems is to reproduce a real-world scene in such a way that a high visual quality is obtained. A crucial aspect in this regard is, naturally, the quality of the hardware components of the camera device. There are, however, always some undesired limitations imposed by the sensor of the camera.

7. 5. Topics in polynomial sequences defined by linear recurrences

   Author : INNOCENT NDIKUBWAYO; Boris Shapiro; Rikard Bøgvad; Tamás Forgács; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; recurrence relation; q-discriminant; generating function; polynomial sequence; support; real zeros; matematik; Mathematics;

   Abstract : This licentiate consists of two papers treating polynomial sequences defined by linear recurrences.In paper I, we establish necessary and sufficient conditions for the reality of all the zeros in a polynomial sequence {P_i} generated by a three-term recurrence relation P_i(x)+ Q_1(x)P_{i-1}(x) +Q_2(x) P_{i-2}(x)=0 with the standard initial conditions P_{0}(x)=1, P_{-1}(x)=0, where Q_1(x) and Q_2(x) are arbitrary real polynomials.
