  4. 12. Estimation of wood fibre length distributions from censored mixture data

    Author : Ingrid Svensson; Sara Sjöstedt - de Luna; Lennart Bondesson; Aila Särkkä; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; censoring; fibre length distribution; identifiability; increment core; length bias; mixture; stochastic EM algorithm; Mathematical statistics; Matematisk statistik;

    Abstract : The motivating forestry background for this thesis is the need for fast, non-destructive, and cost-efficient methods to estimate fibre length distributions in standing trees in order to evaluate the effect of silvicultural methods and breeding programs on fibre length. The usage of increment cores is a commonly used non-destructive sampling method in forestry. READ MORE

  5. 13. Nonlinear Structural Identification Using a Multi-Harmonic  Frequency Response Functions

    Author : Vahid Yaghoubi Nasrabadi; Thomas Abrahamsson; Andreas Linderholt; Martin Magnevall; Chalmers; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear structure; inverse problem; grey box system identification; finite element model updating; identifiability; Fisher information matrix; multi-harmonic frequency response function; Maskinteknik; Mechanical Engineering;

    Abstract : In industrial structural dynamics problems, linear FE-models commonly serve to represent the global structural behavior. However, when test data are available they often show evidence of nonlinear dynamic characteristics. In that case, an initial linear model may be judged insufficient in representing the dynamics of the structure. READ MORE

  6. 14. Concepts and Algorithms for Non-Linear System Identifiability

    Author : Torbjörn Andersson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Recently, commutative algebra and differential algebra have come to use as mathematical tools for solving problems in automatic control. We will use these tools to answer questions regarding identifiability for models given as a set of differential polynomials. READ MORE

  7. 15. Unequal Valuations of Lives and What to Do About It : The Role of Identifiability, Numbers, and Age in Charitable Giving

    Author : Hajdi Moche; Daniel Västfjäll; Arvid Erlandsson; Erkin Asutay; Annika Wallin; Linköpings universitet; []

    Abstract : Many people choose to donate money to help victims of humanitarian crises. However, people’s donation decisions often fail to reflect that all victims are equally valuable to help. Instead, some victims seem to be favored. READ MORE
