3. 17. Stochastic model updating and model selection with application to structural dynamics

   Författare :Majid Khorsand Vakilzadeh; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element model; Bayesian model selection; Bayesian model updating; stochastic simulation; Bootstrapping; Subspace system identification; Uncertainty quantification;

   Sammanfattning : Uncertainty induced by our incomplete state of knowledge about engineering systems and their surrounding environment give rise to challenging problems in the process of building predictive models for the system behavior. One such challenge is the model selection problem, which arises due to the existence of invariably multiple candidate models with different mathematical forms to represent the system behavior, and so there is a need to assess their plausibility based on experimental data.

4. 18. Understanding Multicore Performance : Efficient Memory System Modeling and Simulation

   Författare :Andreas Sandberg; Erik Hagersten; David Black-Schaffer; David A. Wood; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Architecture; Simulation; Modeling; Sampling; Caches; Memory Systems; gem5; Parallel Simulation; Virtualization; Sampling; Multicore; Datavetenskap; Computer Science;

   Sammanfattning : To increase performance, modern processors employ complex techniques such as out-of-order pipelines and deep cache hierarchies. While the increasing complexity has paid off in performance, it has become harder to accurately predict the effects of hardware/software optimizations in such systems. LÄS MER

5. 19. Mimic: A Microscopic Simulation Model for Rural Road Traffic

   Författare :Stig O. Simonsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computer model; time headway; log normal distribution; Chi-Square test; gap-acceptance; rural road network; car-following; traffic simulation model; alignment; sight distance; Kolmogorov-Smirnoff test; software system; statistics;

   Sammanfattning : The purpose of this dissertation is to outline the theoretical basis of a road traffic simulation model, named Mimic, that constitutes the key elements of a system for estimating road user effects and environmental impacts. The simulation model suggested is a microscopic road traffic simulation model and it is structured to be used for networks of rural roads. LÄS MER

7. 20. Distributed System Simulation Methods : For Model-Based Product Development

   Författare :Robert Braun; Petter Krus; Nigel Johnston; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Distributed system simulation can increase performance, re-usability and modularity in model-based product development. This thesis investigates four aspects of distributed simulation: multi-threaded simulations, simulation tool coupling, distributed equation solvers and parallel optimization algorithms. LÄS MER
