  1. 1. Modeling pavement performance based on data from the Swedish LTPP database predicting cracking and rutting

    Detta är en avhandling från Stockholm : Kungliga tekniska högskolan. Institutionen för transportvetenskap

    Författare :Markus Svensson; KTH.; Statens väg- och transportforskningsinstitut.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; performance predictions; LTPP; rut; crack; statistical modeling; 32 Road: Pavement design; 32 Road: Pavement design; Cracking; Rutting wheel ; Prediction; Calculation; Mathematical model; Flexible pavement; Performance; Sprickbildning; Spårbildning; Förutsägelser; Beräkning; Matematiska modeller; Flexibla överbyggnader; Prestanda;

    Sammanfattning : The roads in our society are in a state of constant degradation. The reasons for this are many, and therefore constructed to have a certain lifetime before being reconstructed. To minimize the cost of maintaining the important transport road network high quality prediction models are needed. LÄS MER

  2. 2. Phenomenology of Diffractive Higgs Production and Large Extra Dimensions

    Detta är en avhandling från Department of Theoretical Physics, Lund University

    Författare :Malin Sjödahl; Lund University.; Lunds universitet.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ADD; black holes; gravitational scattering; quantum field theory; Elementary particle physics; LHC; cosmic rays; Kosmisk strålning; högenergi; High energy interactions; kvantfältteori; Elementarpartikelfysik; Higgs; large extra dimensions; Diffractive;

    Sammanfattning : This thesis is based on phenomenological predictions for high energy particle collisions from two different theoretical models. The first two papers deal with uncertainties in exclusive reactions of type proton + proton -> proton + proton + Higgs. LÄS MER

  3. 3. Simulation of the dynamics of fiber suspension flows

    Detta är en avhandling från Sundsvall : Mid Sweden University

    Författare :Stefan B Lindström; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibre; fibre suspension; simulation; paper; papermaking; forming; fibre orientation distribution; fibre flexibility; viscosity; first normal stress difference; fluid flow; simple shear flow; two-way coupling; three-dimensional;

    Sammanfattning : A new model for simulating non-Brownian flexible fibres suspended in a Newtonian fluid has been developed. Special attention has been given to include realistic flow conditions found in the industrial papermaking process in the key features of the model; it is the intention of the author to employ the model in simulations of the forming section of the paper machine in future studies.

  5. 5. On state space structure and average case complexity in random K-SAT problems

    Detta är en avhandling från Stockholm : KTH

    Författare :John Ardelius; KTH.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Sammanfattning : This thesis gives an introduction to a currently active area in the cross-section between theoretical computer science and theoretical physics. In the last ten years it has been suggested that critical behaviour, usually seen in models from condensed matter physics, may be responsible for the intractability of NP complete computation problems.
