1. 26. Model-based outlier adjustments for samples from skewed populations

   Författare :Olivia Ståhl; Dan Hedlin; Daniel Thorburn; Carl-Erik Särndal; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Survey sampling; outliers; value modification; winsorization; statistik; Statistics;

   Sammanfattning : Many populations encountered in practice are skewed to the right and contain a couple of values which are much larger than the bulk of the data. Using standard estimators to estimate for example the mean value of such a population is likely to result in a large variance. LÄS MER

3. 27. Outdoor Comfort in Cold Climates : Integrating Microclimate Factors in Urban Design

   Författare :Saeed Ebrahimabadi; Sigrid Reiter; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture; Arkitektur;

   Sammanfattning : Designing urban spaces that provide outdoor comfort is an important but challenging goal in subarctic climates. An approach to urban design that is sensitive to subarctic climatic conditions is essential, but this requires effective incorporation of urban climate knowledge into urban design, which presently is impeded by several barriers.

4. 28. A teacher-centred design system to integrate digital technologies in secondary mathematics classrooms

   Författare :Miguel Perez; Marianna Bosch; John Monaghan; Linnéuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Design; digital technologies; praxeology; teachers; professional development; inquiry systems; agile educational design; Mathematical Education; Matematikdidaktik;

   Sammanfattning : Despite efforts made by teachers and researchers, studies show that digital technologies have not improved conditions for teaching and learning mathematics to the degree expected by stakeholders inside as well as outside the school system.In this research, the problem of the integration of digital technologies is addressed through the perspective of design.

5. 29. End-user activity-based service design in the built environment context : Exploring everyday life in KTH Live-in-Lab

   Författare :Elena Malakhatka; Per Lundqvist; Marco Molinari; Shaun West; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; service design; human activity system; building system; service system; actors network analysis; living lab; sustainable building; Energy Technology; Energiteknik; Building Service and Energy Systems; Installations- och energisystem;

   Sammanfattning : The main goal of this thesis is to communicate the motivation, process, and result of the research project dedicated to exploring the topic of Service Design, based on end-user activities analysis in the built environment context. We have elected to use a KTH Live-in-Lab as a testbed in relation to the chosen living lab network of actors and stakeholders. LÄS MER

7. 30. Optimal design solutions of road bridges considering embedded environmental impact and cost

   Författare :Elisa Khouri Chalouhi; Raid Karoumi; Costin Pacoste; Mario Plos; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural optimization; Automated design; Road bridges; Environmental impact; Global warming potential; Cost; Overhang bridge slab; Edge beam; Composite bridges; Strukturell optimering; Automatiserad dimensionering; Vägbroar; Miljöpåverkan; Global uppvärmningspotential; Kostnad; Överhängande broplatta; Kantbalk; Kompositbryggor.; Bro- och stålbyggnad; Structural Engineering and Bridges;

   Sammanfattning : Continuous urbanization and population growth are increasing the demand for transportation infrastructure such as bridges. The construction of these structures represents a significant economic investment for public authorities; moreover, the construction sector accounts for a big portion of CO2 emissions. LÄS MER
