  1. 11. Algorithms for a Partially Regularized Least Squares Problem

    Författare :Ingegerd Skoglund; Tommy Elfving; Inge Söderkvist; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Least squares; Regularization; Block-matrices; Conjugate gradient; QR-factorization; Cross-validation; Numerical analysis; Numerisk analys;

    Sammanfattning : Vid analys av vattenprover tagna från t.ex. ett vattendrag betäms halten av olika ämnen. Dessa halter är ofta beroende av vattenföringen. LÄS MER

  2. 12. Självstyre eller samförvaltning? : problem och möjligheter utifrån en studie av världsarvet Laponia

    Författare :Christina Rådelius; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political Science; Statsvetenskap;

    Sammanfattning : Because of its importance for indigenous biodiversity and the local Sami culture, the Laponian area, in the north of Sweden, was declared a World Heritage Site Area by the UN organization UNESCO in 1996. Most of the area is protected because it encompasses national parks and nature reserves and is state owned, and, thus, managed by the County Administrative Board. LÄS MER

  3. 13. The drumlin problem : streamlined subglacial bedforms in southern Sweden

    Författare :Tom Dowling; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; glacial flow; drumlin; self organising maps; LiDAR;

    Sammanfattning : This thesis investigates stream-lined subglacial bedforms (often referred to as drumlins) in southern Sweden. The broad aim of this is to contribute to the solution of the ‘drumlin problem’. The term drumlin has come to be applied to a wide range of features whose internal architecture (core) and overall morphology are seen to vary greatly. LÄS MER

  4. 14. Multidimensional inverse problems in imaging and identification using low-complexity models, optimal mass transport, and machine learning

    Författare :Axel Ringh; Johan Karlsson; Rodolphe Sepulchre; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inverse problems; convex optimization; variational regularization; trigonometric moment problems; optimal mass transport; computed tomography; machine learning; analytic interpolation; delay systems; Inversa problem; konvex optimering; variationell regularisering; trigonometriska momentproblem; optimal masstransport; datortomografi; maskininlärning; analytisk interpolation; system med tidsfördröjning; Mathematics; Matematik;

    Sammanfattning : This thesis, which mainly consists of six appended papers, primarily considers a number of inverse problems in imaging and system identification.In particular, the first two papers generalize results for the rational covariance extension problem from one to higher dimensions.

  5. 15. On the Fundamentals of the Engineering Design Process

    Författare :Damien Motte; Innovation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; systems theory; design theory; engineering design; product development; problem solving; creativity; machine design; maskinkonstruktion;

    Sammanfattning : In an industrial context when the product development cycles are shortened and constraints on technical innovations are high, it is very important to provide a very efficient and effective engineering design activity. In the current engineering design literature, most methodologies are by and large based on the so-called systematic engineering design approach. LÄS MER
