  1. 6. Processes on Integer Partitions and Their Limit Shapes

    Författare :Markus Jonsson; Kimmo Eriksson; Johan Jonasson; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : This thesis deals with processes on integer partitions and their limit shapes, with focus on deterministic and stochastic variants on one such process called Bulgarian solitaire. The main scientific contributions are the following. LÄS MER

  3. 7. Mapping the concept of industrialized bridge construction : potentials and obstacles

    Författare :Johan Larsson; Christina Claeson-Jonsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Improving productivity is a central challenge in most industries and so also in construction. In many countries, such as Great Britain and US (Egan, 1998; Huang et al., 2009; Teichholz, 2001), governmental reports and research publications have highlighted the slow growth of productivity in the construction industry.

  4. 8. Efficient Methods to Calculate Mutual Coupling between Generic Antennas on Large Platforms

    Författare :Johan Malmström; B. Lars G. Jonsson; Lars Pettersson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis presents research on methods for calculating the mutual coupling between antennas. The mutual coupling between antennas is a measure of the amount of energy transmitted from one antenna that is received by another, and is a key parameter when installing antennas on platforms, such as aircraft.

  5. 9. Model-Based Protocol Testing in an Erlang Environment

    Författare :Johan Blom; Bengt Jonsson; Sven-Olof Nyström; Bernhard Aichernig; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Testing; Erlang; Model-Based Testing; Symbolic Execution; Communication Protocols; Datavetenskap; Computer Science;

    Sammanfattning : Testing is the dominant technique for quality assurance of software systems. It typically consumes considerable resources in development projects, and is often performed in an ad hoc manner. This thesis is concerned with model-based testing, which is an approach to make testing more systematic and more automated. LÄS MER

  7. 10. Effects of manufacturing chain on mechanical performance : Study on heat treatment of powertrain components

    Författare :Johan Fahlkrans; Arne Melander; Bengt Lindberg; Stefan Jonsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat treatment; case hardening; carburising; induction hardening; gas quenching; tempering; straightening; fatigue strength; contact fatigue; fracture mechanics; Industriell ekonomi och organisation; Industrial Economics and Management; Production Engineering; Industriell produktion; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The increasing demands for lightweight designs with high strength call for improved manufacturing processes regarding heat treatment of steel. The manufacturing process has considerable potential to improve the mechanical performance and to obtain more reliable results with less variation. LÄS MER
