  2. 21. Stochastic model updating and model selection with application to structural dynamics

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

    Abstract : 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. 22. Industrial buying behavior of large Swedish firms : case studies of the purchase of educational services

    Author : Åsa Wallström; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Industrial Marketing; Industriell marknadsföring;

    Abstract : The lack of studies focusing on industrial buying behavior in the purchase of professional services, coupled with the increased corporate need of investing in employee training and education, created the foundation for the research problem of this thesis: How can the buying behavior of large Swedish firms be characterized when they purchase educational services in the area of sales and marketing? Based on this research problem, five research questions were developed. A frame of reference describing industrial buying behavior in the purchase of professional services was then created, based on the literature review. READ MORE

  5. 23. Modeling and identification of biological systems with emphasis on osmoregulation in yeast

    Author : Peter Gennemark; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; osmotic stress; Saccharomyces cerevisiae; model identification; parameter estimation; model selection; ordinary differential equations;

    Abstract : This thesis deals with two topics in the area of systems biology. Thefirst topic, model identification, concerns the problem ofautomatically identifying a mathematical model of a biochemical systemfrom experimental data. READ MORE

  6. 24. Efficient training of interpretable, non-linear regression models

    Author : Oskar Allerbo; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sparse regression; kernel regression; neural network regression; early stopping; bandwidth selection;

    Abstract : Regression, the process of estimating functions from data, comes in many flavors. One of the most commonly used regression models is linear regression, which is computationally efficient and easy to interpret, but lacks in flexibility. READ MORE

  7. 25. Doctoral Thesis: Massive MIMO in Real Propagation Environments

    Author : Xiang Gao; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Massive MIMO; very-large MIMO; multi-user MIMO; channel measurements; channel modeling; 5G; sum-rate capacity; antenna selection; signal processing;

    Abstract : Mobile communications are now evolving towards the fifth generation (5G). In the near future, we expect an explosive increase in the number of connected devices, such as phones, tablets, sensors, connected vehicles and so on. Much higher data rates than in today's 4G systems are required. READ MORE
