  1. 1. Social causality in motion : Visual bias and categorization of social interactions during the observation of chasing in infancy

    Author : Martyna A. Galazka; Pär Nyström; Gustaf Gredebäck; Moritz Daum; Uppsala universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social causality; motion; animacy perception; chasing goal-directed motion; heat-seeking; EEG; P400; Nc; spatial proximity; non-contact causality; functional specialization; specialized perception; evolution; Psychology; Psykologi;

    Abstract : Since the seminal work of Fritz Heider and Marienne Simmel (1944) the study of animacy perception, or the perception and attribution of life from the motion of simple geometrical shapes has intrigued researchers. The intrigue for psychologists and vision scientists then and today centered on the stark disconnect between the simplicity of the visual input and the universal richness of the resulting percept.

  2. 2. A Treatise on Measuring Wiener-Granger Causality

    Author : Mehrdad Jafari-Mamaghani; Joanna Tyrcha; Sebastiano Stramaglia; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Wiener-Granger causality; Information theory; Kernel canonical correlation; Systems Microscopy; Cell migration.; Mathematical Statistics; matematisk statistik;

    Abstract : Wiener-Granger causality is a well-established concept of causality based on stochasticity and the flow of time, with applications in a broad array of quantitative sciences. The majority of methods used to measure Wiener-Granger causality are based on linear premises and hence insensitive to non-linear signals. READ MORE

  3. 3. Switched Bond Graphs : Simulation and Analysis

    Author : Krister Edström; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bond graphs; Hybrid systems; Modeling; Simulation; Causality; Discontinuities;

    Abstract : In this thesis an approach to modeling and simulation of mode switching systems is investigated. This approach, switched bond graphs, is an extension of the bond graph language in the sense that it allows modeling of mode switching phenomena.The classical bond graph language as well as the switched bond graph language are presented.

  4. 4. A Procedure for Ecological Tiered Assessment of Risks (PETAR)

    Author : Rosana Moraes; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local scale; regional scale; developing country; Brazil; rain forest; multiple stressors; PETAR; ecological risk assessment; causality;

    Abstract : Institutions in developed countries have proposed several Ecological Risk Assessment (ERA) procedures, and the majority of study cases have been carried out there. The use of (often expensive) existing ERA procedures in developing countries is questionable given their limited resources and scarce background information of relevance for risk assessments.

  5. 5. Statistical Inference of Information in Networks : Causality and Directed Information Graphs

    Author : Sina Molavipour; Mikael Skoglund; Deniz Gündüz; KTH; []

    Abstract : Over the last decades, the advancements in measurement, collection, and storage of data have provided tremendous amounts of information. Thus, it has become crucial to extract valuable features and analyze the characteristics of data. As we study more complex systems (e.g. READ MORE
