  1. 1. Toward higher-order network models

    Författare :Ludvig Bohlin; Martin Rosvall; Ludvig Lizana; Tina Eliassi-Rad; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; network science; complex systems; complex networks; network analysis; higher-order networks; community detection; citation networks; network modeling; fysik; Physics;

    Sammanfattning : Complex systems play an essential role in our daily lives. These systems consist of many connected components that interact with each other. LÄS MER

  3. 2. Chemistry: content, context and choices : towards students' higher order problem solving in upper secondary school

    Författare :Karolina Broman; Eva Silfver; Dan Johnels; Judith Bennett; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; chemistry education; upper secondary students; meaningful learning; higher order thinking; problem solving; context-based learning; interest; educational choice; identity; kemididaktik; didactics of chemistry;

    Sammanfattning : Chemistry is often claimed to be difficult, irrelevant, and uninteresting to school students. Even students who enjoy doing science often have problems seeing themselves as being scientists. This thesis explores and challenges the negative perception of chemistry by investigating upper secondary students’ views on the subject. LÄS MER

  4. 3. Higher order differential operators on graphs

    Författare :Jacob Muller; Pavel Kurasov; Ram Band; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Almost periodic functions; differential operators on metric graphs; quantum graphs; estimation of eigenvalues;

    Sammanfattning : This thesis consists of two papers, enumerated by Roman numerals. The main focus is on the spectral theory of -Laplacians. Here, an -Laplacian, for integer , refers to a metric graph equipped with a differential operator whose differential expression is the -th derivative. LÄS MER

  5. 4. Higher order finite difference methods for wave propagation problems

    Författare :Eva Mossberg; Bertil Gustafsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Numerical Analysis; Numerisk analys;

    Sammanfattning : Wave propagation is described by the wave equation, or in the time-periodic case, by the Helmholtz equation. For problems with small wavelengths, high order discretizations must be used to resolve the solution. Two different techniques for finding compact finite difference schemes of high order are studied and compared. LÄS MER
