  1. 11. Feasible computation of generalized linear mixed models with application to credit risk modelling

    Författare :Md. Moudud Alam; Göran Boström; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Credit risk; cluster correlation; GLMM; large data; two-step pseudo likelihood estimation; defaults contagion; predictive likelihood; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Statistics; Statistik; Statistics; Statistik; Complex Systems – Microdata Analysis;

    Sammanfattning : This thesis deals with developing and testing feasible computational procedures to facilitate the estimation of and carry out the prediction with the generalized linear mixed model (GLMM) with a scope of applying them to large data sets. The work of this thesis is motivated from an issue arising incredit risk modelling. LÄS MER

  2. 12. Prediction-driven approaches to discrete choicemodels with application to forecasting car typedemand

    Författare :Shiva Habibi; Anders Karlström; Stefan Mabit; KTH; []
    Nyckelord :Transportvetenskap; Transport Science;

    Sammanfattning : Models that can predict consumer choices are essential technical support fordecision makers in many contexts. The focus of this thesis is to address predictionproblems in discrete choice models and to develop methods to increase the predictivepower of these models with application to car type choice.

  3. 13. Towards application of explicit likelihoods in inference for Dark Matter Direct Detection

    Författare :Pueh-Leng Tan; Jan Conrad; Klas Hultqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Sammanfattning : Despite the many empirical hints for the existence of Dark Matter in the Universe, Dark Matter has yet to be observed experimentally, be it directly through its scatterings in detectors, indirectly through its annihilation in the galaxy, or implicitly through its production and decay in particle colliders. Even though observations from astrophysics and cosmology placed constraints on the Dark Matter energy density and self-interaction cross section and with Standard Model particles, much about the nature of Dark Matter is still unknown, leaving much to the creativity of model builders.

  4. 14. Simulation of Combustion and Mixture Formation for Gasoline Direct Injection Engine Application

    Författare :Chen Huang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VSB2; Reitz-KHRT; gasoline surrogate; LISA; sensitivity study.; Reitz-Diwakar; Trajectory collision; laminar flame speed; chemical kinetics; TAB; Rosin-Rammler; ignition delay; OpenFOAM; ethanol; O Rourke collision; SMD; hollow cone spray; liquid penetration;

    Sammanfattning : The development and introduction of new engine technologies are primarily motivated by the need to comply with increasingly stringent emissions legislation and to reduce fuel consumption. One of the most important of these new engine technologies is direct gasoline injection, which is considered to be an important and cost-effective measure to meet both targets. LÄS MER

  5. 15. Development and application of techniques for predicting and analysing phonon-derived materials properties

    Författare :Fredrik Eriksson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lattice Thermal Conductivity; Force Constants; Green- Kubo; Peierls-Boltzmann Transport; Molecular Dynamics;

    Sammanfattning : The thermodynamic properties of materials are of great interest for both scientists and engineers. A large contribution to many properties stems from the vibrational motion of the atoms in the material. An understanding of the dynamics of the vibrating atoms is therefore important for many other areas as well, including, e.g. LÄS MER
