  1. 11. System identification of large-scale linear and nonlinear structural dynamicmodels

    Författare :Vahid Yaghoubi Nasrabadi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element model; Surrogate modeling; Bootstrapping; Polynomial chaos expansion; System identification; Exponential integration; Uncertainty quantification;

    Sammanfattning : System identification is a powerful technique to build a model from measurement data by using methods from different fields such as stochastic inference, optimization and linear algebra. It consists of three steps: collecting data, constructing a mathematical model and estimating its parameters. LÄS MER

  3. 12. Bootstrapping Named Entity Annotation by Means of Active Machine Learning

    Författare :Fredrik Olsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; corpus creation; data annotation; active learning; named entity recognition; machine learning; computational linguistics; natural language processing; information refinement;

    Sammanfattning : This thesis describes the development and in-depth empirical investigation of a method, called BootMark, for bootstrapping the marking up of named entities in textual documents. The reason for working with documents, as opposed to for instance sentences or phrases, is that the BootMark method is concerned with the creation of corpora. LÄS MER

  4. 13. Innovation in Complex Adaptive Systems

    Författare :Petter Törnberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Society; Transitions; Complexity; Innovation Society; Wicked Systems; Technical change; EvoDevo; Innovation; Exaptive Bootstrapping; Generative Entrenchment; Niche Construction Theory;

    Sammanfattning : Our society is increasingly beset by a range of interrelated crises - with the financial crisis, the energy crisis, and the global warming crisis as leading examples - forming a "meta-crisis" with its roots in processes deeply entrenched in society (Lane et al., 2011), and emanating from large-scale complex adaptive systems so strongly interlinked that they are hard to even define and delimit.

  5. 14. On Pre-deployment Assessment and Security Bootstrapping of Industrial Communication Networks

    Författare :Apala Ray; Mats Björkman; Leonardo Martucci; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Sammanfattning : The severity of cyber threats towards existing and future industrial systems has resulted in an increase of security awareness in the industrial automation domain. Compared to traditional information systems, industrial communication systems have different performance and reliability requirements. LÄS MER
