  1. 21. Causal Combinatorics : Edges of the Characteristic Imset Polytopes

    Författare :Petter Restadh; Svante Linusson; Liam Solus; James Cussens; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics;

    Sammanfattning : Explaining data in a concise and efficient manner has become increasingly important in today's society. This thesis pertains to the problem of finding causal links within data, and how that can be done from a mathematical perspective. Using the framework of graphical models has several advantages, from interpretability to efficiency. LÄS MER

  3. 22. På tal om matematik : matematiken, vardagen och den matematikdidaktiska diskursen

    Författare :Eva Riesbeck; Lars-Ove Dahlgren; Ingrid Andersson; Astrid Pettersson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; school-mathematics; every-day life; discourse; education; language; discursive boundary crossing; meta-language; Skolmatematik; vardag; diskurs; didaktik; språk; diskursiva gränser; metaspråk; Education; Pedagogik;

    Sammanfattning : The aim of this dissertation is to describe and analyze how discourse as a theoretical and didactical concept can help in advancing knowledge about the teaching of mathematics in school. The dissertation has been written within a socio-cultural perspective where active participation and support from artefacts and mediation are viewed as important contributions to the development of understanding.

  4. 23. Toward Robust Optimization of Adaptive Radiation Therapy

    Författare :Michelle Böck; Anders Forsgren; Minsun Kim; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimization; adaptive radiation therapy; radiation therapy treatment planning; uncertainty; robust optimization; stochastic programming; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Sammanfattning : Adaptive radiation therapy is an evolving cancer treatment approach which relies on adapting the treatment plan in response to patient-specific interfractional geometric variations occurring during the fractionated treatment. If those variations are not addressed through adaptive replanning, the resulting treatment quality may be compromised. LÄS MER

  5. 24. Fire safety design of road tunnels

    Författare :Jonatan Gehandler; Avdelningen för Brandteknik; []
    Nyckelord :HUMANIORA; HUMANITIES; Brandsäkerhet; vägtunnlar; design; Riskbedömning; Road tunnel fire safety; Fire safety engineering; design framework; risk evaluation;

    Sammanfattning : This thesis can be described as a journey in performance-based fire safety design. Along the way questions such as what fire safety is, how it can be measured, whether we are posing the right questions, or engineer the best solutions, have arisen. LÄS MER

  7. 25. On some topics in operator theory : An unfinished story about mathematical control

    Författare :Eskil Rydhe; Harmonic Analysis and Applications; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carleson embeddings; complex analysis; control theory; functional models; Hankel operators; harmonic analysis; operator theory; Triebel–Lizorkin spaces; vector-valued analytic functions;

    Sammanfattning : This thesis considers differentiation of non-negative, fractional order, composed with Hardy spacetypeHankel operators. H2-boundedness is characterized in terms of a reproducing kernel thesis. LÄS MER
