  1. 1. Kan man räkna med PISA och TIMSS? : Relevansen hos internationella storskaliga mätningar i matematik i en nationell kontext

    Författare :Samuel Sollerman; Astrid Pettersson; Lovisa Sumpter; Christian Lundahl; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; International large-scale assessment; Mathematics; Validity; Validation; Relevance; Assessment; PISA; TIMSS; Mathematics education; matematikämnets didaktik; Mathematics Education;

    Sammanfattning : The overall purpose of the thesis is to contribute to the knowledge of relevance of international large-scale assessments (ILSAs) in mathematics, when these are to be used and interpreted in a national context. If a nation is to engage in ILSAs, draw conclusions from them and act on them, one should be aware of what they are measuring and how well it fits in with the national mathematics education and the mathematics they are trying to teach their students.

  3. 2. Robust large-scale mapping and localization : Combining robust sensing and introspection

    Författare :Daniel Adolfsson; Henrik Andreasson; Martin Magnusson; Stephanie Lowry; Timothy Barfoot; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SLAM; Localization; Robustness; Radar;

    Sammanfattning : The presence of autonomous systems is rapidly increasing in society and industry. To achieve successful, efficient, and safe deployment of autonomous systems, they must be navigated by means of highly robust localization systems. LÄS MER

    Sammanfattning : Water has always had a controlling influence on the earth’s evolution. Understanding and modelling the large-scale hydrological cycle is important for climate prediction and water-resources studies. LÄS MER

  5. 4. Energy Management in Large scale Solar Buildings : The Closed Greenhouse Concept

    Författare :Amir Vadiee; Viktoria Martin; Philip Griffiths; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Energy Storage; Energy Saving; Thermoeconomic Assessment; Energy Management Scenario; Micro Climate Control; Solar Building; Closed Greenhouse; SRA - Energy; SRA - Energi;

    Sammanfattning : Sustainability has been at the centre of global attention for decades. One of the most challenging areas toward sustainability is the agricultural sector. Here, the commercial greenhouse is one of the most effective cultivation methods with a yield per cultivated area up to 10 times higher than for open land farming. LÄS MER

  7. 5. Statistical modeling in international large-scale assessments

    Författare :Inga Laukaityte; Marie Wiberg; Kenny Bränberg; Ewa Rolfsman; Bernard Veldkamp; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multilevel model; plausible values; sampling weights; missing information; multiple imputation; non-monotone missing pattern; TIMSS; PISA; Statistics; statistik; pedagogik; Education;

    Sammanfattning : This thesis contributes to the area of research based on large-scale educational assessments, focusing on the application of multilevel models. The role of sampling weights, plausible values (response variable imputed multiple times) and imputation methods are demonstrated by simulations and applications to TIMSS (Trends in International Mathematics and Science Study) and PISA (Programme for International Student Assessment) data.
