  1. 1. Hilbert space frames and bases : a comparison of Gabor and wavelet frames and applications to multicarrier digital communications

    Författare :Niklas Grip; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : Several signal processing applications today are based on the use of different transforms. The signals under consideration are written as a linear combination (or series) of some predefined set of functions. Traditionally, orthogonal bases have been used for this purpose, for example, in the discrete Fourier transform. LÄS MER

  3. 2. Digital Product Innovation : Building Generative Capability through Architectural Frames

    Författare :Fredrik Svahn; Ola Henfridsson; Jonny Holmström; Sandeep Purao; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; digital innovation; product innovation; generativity; modularity; patterns; architecture; architectural frames;

    Sammanfattning : Over the last decades we have witnessed a profound digitalization of tangible products. While this shift offers great opportunities, it also exposes product developing industries to significant challenges. LÄS MER

  4. 3. Frames of threat and solidarity : Dynamics of media discourse on immigration in Sweden

    Författare :Victoria Yantseva; Giangiacomo Bravo; Kostiantyn Kucher; Gergei Farkas; Simon Lindgren; Linnéuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology; Sociologi;

    Sammanfattning : This dissertation aims to analyse media discourse about immigration in Sweden in the last decade. To meet this goal, it uses large-scale textual data collected from various media resources, such as mainstream newspapers, social media (Twitter and Facebook) and an online forum. LÄS MER

  5. 4. Connections for Timber-Framed Structures - Assembly Properties and Structural Behaviour

    Författare :Dan Engström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frames; nails; connections; structures; interaction; glue; assembly; timber; economy; semi-rigidity; adhesive; joints; splices;

    Sammanfattning : By tradition, the design and development of connections has focused on the optimization of strength and stiffness. The subject of this thesis is the interaction between the assembly and structural properties of connections for timber-framed structures. LÄS MER

  7. 5. Wavelet and gabor frames and bases : approximation, sampling and applications

    Författare :Niklas Grip; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : This thesis is devoted to both theoretical and practical aspects of applied mathematics. It consists of three main parts: Part I consists of an application-oriented introduction to the theory of frames and bases for separable Hilbert spaces, as well as an introduction to the main tools used in the remaining Chapters: Time-frequency analysis, Gabor frames and wavelet frames.
