  2. 1. Mechanical Properties of Arteries : Identification and Application

    Author : Jan-Lucas Gade; Jonas Stålhand; Carl-Johan Thore; Håkan Johansson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this Licentiate of Engineering thesis, a method is proposed that identifies the mechanical properties of arteries in vivo. The mechanical properties of an artery are linked to the development of cardiovascular diseases. READ MORE

  4. 2. Fast Algorithms for Integral Equations and Least Squares Identification Problems

    Author : Stefan Ljung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fast algorithms; Integral equations; Least squares; Identification;

    Abstract : This work is concerned with fast algorithms for integral equations and least squares identification problems.The presentation is divided into three parts. In the first part a fast algorithm for solving systems oflinear equations with a matrix that is alm ost Toeplitz is derived and applied to Fredholm integral equations with stationary kernels.

  5. 3. Interpretive Functions of Adjectives in English : A Cognitive Approach

    Author : Helena Frännhag; Carita Paradis; Kristin Davidse; Engelska; []
    Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; adjective; meaning; meaning creation; interpretation; formal interpretive function; semantic interpretive function; kind identification; element identification; identity provision; stipulation; specification; Languages and linguistics; Språkvetenskap; Lingvistik; Linguistics; Engelsk språkvetenskap; English; specification; stipulation; adjective; noun; meaning creation; cognitive semantics; interpretation; formal interpretive function; semantic interpretive function; kind identification; identity provision; element identification;

    Abstract : This thesis presents a theoretical discussion of meaning creation in general, and interpretive functions of English adjectives in particular. The discussion rests on a dynamic view of meaning and interpretation, according to which there are no fixed linguistics meanings – not even for single lexemes. READ MORE

  6. 4. System identification of large-scale linear and nonlinear structural dynamicmodels

    Author : Vahid Yaghoubi Nasrabadi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element model; Surrogate modeling; Bootstrapping; Polynomial chaos expansion; System identification; Exponential integration; Uncertainty quantification;

    Abstract : System identification is a powerful technique to build a model from measurement data by using methods from different fields such as stochastic inference, optimization and linear algebra. It consists of three steps: collecting data, constructing a mathematical model and estimating its parameters. READ MORE

  7. 5. The Dirac Equation: Numerical and Asymptotic Analysis

    Author : Hasan Almanasreh; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dirac operator; eigenvalue problem; finite element method; spurious eigenvalues; Petrov-Galerkin; cubic Hermite basis functions; stability parameter; meshfree method; $hp$-cloud; intrinsic enrichment; G-convergence; $ Gamma$-convergence; scattering theory; identification; wave operator; stationary approach; Dirac operator;

    Abstract : The thesis consists of three parts, although each part belongs to a specific subject area in mathematics, they are considered as subfields of the perturbation theory. The main objective of the presented work is the study of the Dirac operator; the first part concerns the treatment of the spurious eigenvalues in the computation of the discrete spectrum. READ MORE
