  2. 1. Improved pharmacometric model building techniques

    Author : Radojka Savic; Mats Karlsson; Siv Jönsson; Matt Hutmacher; Uppsala universitet; []
    Keywords : Model building; Absorption model; Transit compartment model; Nonparametric method; Extended grid method; Semiparametric; Distribution transformation; Shrinkage; Model diagnostics;

    Abstract : Pharmacometric modelling is an increasingly used method for analysing the outcome from clinical trials in drug development. The model building process is complex and involves testing, evaluating and diagnosing a range of plausible models aiming to make an adequate inference from the observed data and predictions for future studies and therapy.

  4. 2. Case studies in omniparametric simulation

    Author : Fredrik Lundin; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; growth model; Ising model; Markov chain; omnithermal simulation; omniparametric simulationpercolatiion; Potts model; parameter estimation; partial observations; random cluster model; Richardson model; simulation driven parameter estimation; two-type Richardson model; omnithermal simulation;

    Abstract : In the eld of particle systems and growths models simulation is an important tool. When explicit calculations are too complex or impossible to perform we may use simulations instead. We adapt a new technique here denoted omniparametric simulation, to the two-type Richardson, Ising and Potts models. READ MORE

  5. 3. Cluster model of disordered systems : application to doped semiconductors and a simple model polymer

    Author : Rolf G. Riklund; Linköpings universitet; []
    Keywords : ;

    Abstract : In this thesis we study with an extended cluster model calculation the combined effect of disorder and electron-electron interaction on the electronic structure of doped semiconductors and a simple model polymer chain. First a one-band model using a Hartree calculation is compared to other authors result for the impurity band using less realistic Hamiltonians. READ MORE

  6. 4. A model for simulation and generation of surrounding vehicles in driving simulators

    Author : Johan Olstam; Jan Lundgren; Pontus Matstoms; Stéphane Espié; Linköpings universitet; []
    Keywords : Traffic; Simulation; Model; Traffic flow; Vehicle; Micro; Overtaking; Vehicle spacing; Deceleration; Acceleration; Mathematical model; Simulator; Road: Traffic theory; Road: Traffic theory; TECHNOLOGY;

    Abstract : Driving simulators are used to conduct experiments on for example driver behavior, road design, and vehicle characteristics. The results of the experiments often depend on the traffic conditions. One example is the evaluation of cellular phones and how they affect driving behavior. READ MORE

  7. 5. The integration of e-business into mature and established companies : a business model approach

    Author : Daniel Kindström; Linköpings universitet; []
    Keywords : e-business; business model; integration; bricks-and-mortar; added value; elektronisk handel; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : The purpose ofthis dissertation is to explore and analyse the implications of the integration of e-business into mature and established companies and how e-business can contribute to business development. Changes in general and e-business in particular have the potential to penetrate different areas of a company and thus we ought to analyse how e-business is integrated into the entire company (both strategically and operationally) if we aim to understand how this happens.
