  1. 16. Origin-destination matrix estimation from traffic counts

    Författare :Anders Peterson; Henrik Edwards; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : For most kind of analyses in the field of traffic modeling, there is a need for origin-destination (OD) matrices, which specify the travel demands between the origin and destination nodes in the network. The process of obtaining OD-matrices is long, complicated and expensive. LÄS MER

  3. 17. Time-resolved plasmonics in designed nanostructures

    Författare :Eleonora Lorek; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plasmon; Nanostructure fabrication; High-order harmonic generation; Photoemission electron microscopy; Focused ion beam; Fysicumarkivet A:2016:Lorek;

    Sammanfattning : A metal nanoparticle can be considered as consisting of a base of positive ion cores and a sea of free electrons. When the free electrons are displaced, for example, by an incident electric field, a restoring force acts on the electrons. The electrons may then oscillate back and forth until equilibrium is reached. LÄS MER

  4. 18. A Damage-Based Interface Model: Application to the Degradation and Failure of a Polycrystalline Microstructure

    Författare :Patrik Cannmo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; damage; polycrystalline microstructure; degradation; slip and dilatation; interfaces; FE-calculations; viscoplasticity; plasticity; failure;

    Sammanfattning : A constitutive model for material interfaces is presented. The model is based on damage coupled to plastic (or viscoplastic) slip and dilatation, and it is able to describe the successive degradation and failure of an interface. LÄS MER

  5. 19. The Origin-Destination Matrix Estimation Problem : Analysis and Computations

    Författare :Anders Peterson; Jan Lundgren; Torbjörn Larsson; Lars-Göran Mattsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Traffic modelling; Travel demand; Origin--Destination matrix; Traffic flow observation; Detector allocation; Estimation.; OD-matris; Trafikflödesobservation; Detektorallokering; Skattning; Trafikmodellering; Reseefterfrågan; Optimization; systems theory; Optimeringslära; systemteori;

    Sammanfattning : For most kind of analyses in the field of traffic planning, there is a need for origin--destination (OD) matrices, which specify the travel demands between the origin and destination nodes in the network. This thesis concerns the OD-matrix estimation problem, that is, the calculation of OD-matrices using observed link flows. LÄS MER

  7. 20. On the Cost of Capital, Profits and the Diffusion of Ideas

    Författare :Has van Vlokhoven; Timo Boppart; Per Krusell; Jan Eeckhout; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cost of capital; Profit share; Capital share; Labor share; Markups; Marginal products; International capital markets; Firm life cycle; Firm entry; Technology diffusion; Search; Networks; Productivity distribution; Economics; nationalekonomi;

    Sammanfattning : Estimating the Cost of Capital and the Profit Share Compensation of the factor of production capital is not directly observed since most firms own part of their capital stock. I develop a new method to estimate capital compensation. LÄS MER
