1. 26. Case studies in omniparametric simulation

   Författare :Fredrik Lundin; Göteborgs universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 27. Game Theory and Agents

   Författare :Stefan J. Johansson; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Game Theory; Multi-Agent Systems; No Free Lunch Theorem; Characteristic Distributions;

   Sammanfattning : A fundamental problem in multi agent systems is conflict resolution. A conflict occurs in general when the agents have to deal with inconsistent goals, such as a demand for shared resources. We investigate how a game theoretic approach may be a helpful and efficient tool in examining a class of conflicts in multi agent systems. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

5. 29. Structural Reliability and Identification with Stochastic Simulation - Application to Railway Mechanics

   Författare :Sadegh Rahrovani; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; model reduction; time-integration; finite element model; sleeper-ballast load characterization; stochastic simulation; Bayesian system identification;

   Sammanfattning : System identification of structures based on measured response data can play a key role in improving reliability based structural designs. However, the experimental limitations of in situ tests and uncertainties of required model complexity together with the inverse nature of system identification give rise to a number of challenging issues.

7. 30. Scattering of seismic waves in random velocity models : Finite difference simulation

   Författare :Lena Frenje; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

   Sammanfattning : The small-scale heterogeneities within the Earth's crust and the effect these heterogeneities have on seismic waves have gained increasing interest in the last 15 years. One approach to study seismic wave scattering is through numerical simulations in random media. LÄS MER
