  1. 21. Learning of probabilistic inference tasks : effects of uncertainty and function form

    Författare :Håkan Alm; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Inference; learning; cognition;

    Sammanfattning : This thesis is concerned with the problem of how people learn to use uncer­tain information for making judgments. The general framework for the thesis is Social Judgment Theory (SJT). First the S3T paradigm, and some research conducted within the paradigm, is briefly described, and a series of four empirical studies is summarized. LÄS MER

  3. 22. Perspectives on Probabilistic Graphical Models

    Författare :Dong Liu; Ragnar Thobaben; Harri Lähdesmäki; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Bayesian methods; graphical models; inference; learning; statistics; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Probabilistic graphical models provide a natural framework for the representation of complex systems and offer straightforward abstraction for the interactions within the systems. Reasoning with help of probabilistic graphical models allows us to answer inference queries with uncertainty following the framework of probability theory. LÄS MER

  4. 23. Spatio-temporal forecasting and optimization for integration of solar energy in urban energy systems

    Författare :Dennis van der Meer; Joakim Widén; Pierre Pinson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forecasting; photovoltaic; electricity use; net load; probabilistic; multivariate; optimization; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

    Sammanfattning : The increasing penetration of non-dispatchable renewable energy sources such as photovoltaic (PV) systems in the electricity generating mix poses challenges to the operational performance of the power system. On the demand side, advanced schemes that increase the flexibility of customer loads and the increase in electrification are set to noticeably alter electricity demand. LÄS MER

  5. 24. Simplified dynamic analysis of railway bridges under high-speed trains

    Författare :Christoffer Johansson; Costin Pacoste; Raid Karoumi; Jose M Goicolea; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic; Railway bridge; High-speed train; Moving load; Multi-span beam; Probabilistic;

    Sammanfattning : The world-wide development of new high-speed rail lines has led to more stringent design requirements for railway bridges. This is mainly due to the fact that a train at high speeds can cause resonance in the bridge superstructure. LÄS MER

  7. 25. Life cycle behaviour of concrete bridges : laboratory test and probabilistic evaluation

    Författare :Markus Bergström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : The structural life for a concrete structure located in an environment where corrosion is promoted by humidity or chlorides from sea or de-icing salt could in general be described in the following manner. The structure is manufactured and is at that point considered to be intact. LÄS MER
