  1. 1. Asymptotic Expansions of Crossing Rates of Stationary Random Processes

    Författare :Oskar Hagberg; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actuarial mathematics; Statistik; operationsanalys; aktuariematematik; programming; operations research; Matematik; Statistics; sea elevation; Mathematics; asymptotic expansions; wave crest hight distribution; Saddle point approximations; Crossing rate; programmering;

    Sammanfattning : The crossing rate of a stationary random process is a valuble tool when studying crest hight distributions and maxima of sea level elevation. This thesis considers two approximation techinques for cases when the crossing rate cannot be exactly computed. LÄS MER

  3. 2. Crossing the threshold : Visualization design and conceptual understanding of evolution

    Författare :Andreas C. Göransson; Lena Tibell; Konrad Schönborn; Anat Yarden; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Evolution; Natural selection; Visualization; Conceptual understanding; Conceptual change;

    Sammanfattning : The theory of evolution is considered the unifying theory of biology. An accurate understanding of evolution is vital both for the understanding of diverse topics in biology, but also for societal issues such as antibiotic resistance or biodiversity. LÄS MER

  4. 3. Modelling Sea Surface Dynamics Using Crossing Distributions

    Författare :Anastassia Baxevani; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistik; actuarial mathematics; programmering; operations research; Statistics; velocities; global maximum; Rice formula; level crossings; Gaussian random fields; programming; aktuariematematik; operationsanalys;

    Sammanfattning : The thesis deals mainly with modelling sea surface dynamics. We consider two different scales. LÄS MER

  5. 4. Planering på gränsen och gränsen för planering - En studie av gränsöverskridande samhällsplanering

    Författare :Heiti Ernits; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; boundaries; boundary work; boundary arrangements; boundary-spanners; strategic spatial planning; collaborative planning; public organization; institutional theory; sociocultural viability theory; translation theory; boundaries;

    Sammanfattning : This exploratory thesis aims to describe and analyze how boundaries emerge, affect planning practices, and how boundaries are managed over time in order to achieve integrated planning processes. This thesis is particularly interested in how the interplay between boundary-spanning and boundary-crossing activities in relation to the organization of strategic spatial planning can be understood from an institutional perspective.

  7. 5. Curve-crossing quantum wavepacket dynamics - Experiment and theory

    Författare :Niklas Gador; KTH; []
    Nyckelord :physical chemistry; molecular;

    Sammanfattning : In this thesis, I present experimental and theoretical workon quantum wavepacket dynamics in potential curve-crossings,using gas-phase Rb2 as working media. Particularly, we havefocused on curve-crossing cases with intermediate strengthcoupling, which leads to complicated wavepacket motion withe.g. large splittings and interference. LÄS MER
