  1. 1. Essays on joint replenishment and multi-echelon inventory systems

    Författare :Andreas Nilsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell logistik; Industrial Logistics;

    Sammanfattning : This Licentiate thesis addresses the topics of Joint Replenishment and Multi-Echelon Inventory Systems. Both are important parts in the concepts and current trends in Supply Chain Management and Logistics. LÄS MER

  3. 2. Preserving physical structure of digital objects through metadata

    Författare :Jörgen Nilsson; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Data och Systemvetenskap; Computer and Systems Science;

    Sammanfattning : In the wake of increased e-government service and overall increase in creation of digital documents, the problem of preserving this kind of "digitally born" material has become imminent. This research focus on how to preserve the physical structure, in other words the layout, colours, logotypes, font characteristics and so on, of digital objects. LÄS MER

  4. 3. Dimensions and projections

    Författare :Anders Nilsson; Peter Wingren; Fredrik Georgsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fractals; Hausdorff dimension; box dimension; packing dimension; projections; MATHEMATICS; MATEMATIK;

    Sammanfattning : This thesis concerns dimensions and projections of sets that could be described as fractals. The background is applied problems regarding analysis of human tissue. One way to characterize such complicated structures is to estimate the dimension. LÄS MER

  5. 4. Entropy and Speech

    Författare :Mattias Nilsson; Bastian Kleijn; Sören Holdt Jensen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speech representation; energy concentration; entropy estimation; manifolds; Acoustics; Akustik;

    Sammanfattning : In this thesis, we study the representation of speech signals and the estimation of information-theoretical measures from observations containing features of the speech signal. The main body of the thesis consists of four research papers. Paper A presents a compact representation of the speech signal that facilitates perfect reconstruction. LÄS MER

  7. 5. Exploring Probabilistic Reasoning : A Study of How Students Contextualise Compound Chance Encounters in Explorative Settings

    Författare :Per Nilsson; Inger Wistedt; Lennart Hellström; Dave Pratt; Växjö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Probabilistic reasoning; randomness; compound chance encounters; contextualisation; differentiation; elaborative variation.; MATHEMATICS; MATEMATIK; Matematikdidaktik; Mathematical Education;

    Sammanfattning : This thesis aims at exploring how probabilistic reasoning arises in explorative learning situations that are random in nature. The focus is especially on what learners with scant experience of formal theories of probability do and can do when dealing with compound random situations in which they are offered opportunities to integrate different probabilistic lines of reasoning.
