  2. 1. The Apparent Arbitrariness of Second-Order Probability Distributions

    Author : David Sundgren; Love Ekenberg; Mats Danielson; Lev Utkin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer and systems science; Data- och systemvetenskap; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : Adequate representation of imprecise probabilities is a crucial and non-trivial problem in decision analysis. Second-order probability distributions is the model for imprecise probabilities whose merits are discussed in this thesis. READ MORE

  4. 2. Test Design for Finite Element Model Updating - Identifiable Parameters and Informative Test Data

    Author : Andreas Linderholt; Thomas Abrahamsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modal tests; test design; identifiability; Fisher information; optimization; data informativeness; model updating; Maskinteknik;

    Abstract : It is important to predict structural phenomena, such as noise and fatigue, stemming from vibrations. To do this, reliable structural dynamic models are needed. To be useful the models have to compare well with reality in the validation against test data; if not, the models should be modified. READ MORE

  5. 3. Model Calibration of Nonlinear Mechanical Systems Using Multi-Harmonic Frequency Response Functions

    Author : Yousheng Chen; Andreas Linderholt; Thomas Abrahamsson; Ahlin Kjell; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element model calibration; multi-harmonic frequency response function; Fisher information matrix; nonlinear structural dynamics; identifiability; data informativeness; Maskinteknik; Mechanical Engineering;

    Abstract : In industry, linear finite element models are commonly employed to represent global structural behavior. It is crucial that the computational models are able to accurately represent the structures’ behavior. This cannot always be achieved by the use of linear models. READ MORE

  6. 4. Dialogue Behavior Management in Conversational Recommender Systems

    Author : Pontus Wärnestål; Arne Jönsson; Lars Degerstedt; Robert Dale; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Natural Language Interaction; Dialogue Systems; Recommender Systems; Dialogue Strategy Management; User Modeling; Preference Management; Computational linguistics; Datorlingvistik;

    Abstract : This thesis examines recommendation dialogue, in the context of dialogue strategy design for conversational recommender systems. The purpose of a recommender system is to produce personalized recommendations of potentially useful items from a large space of possible options. READ MORE

  7. 5. Student modelling based on collaborative dialogue with a learning companion

    Author : Eva L. Ragnemalm; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Abstract : When using computers to support learning, one significant problem is how to fmd out what the student understands and knows with respect to the knowledge the computer system is designed to help him to learn (the system's content goal). This analysis of the student is based on the input he provides to the system and it is evaluated with respect to the content goals of the system. READ MORE
