1. 21. Numerical and Experimental Studies of Deployment Dynamics of Space Webs and CubeSat Booms

   Författare :Huina Mao; Gunnar Tibert; Arne Nordmark; Anders Eriksson; Keith Seffen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deployable structure; Space web; Centrifugal force deployment; Deployable boom; Bi-stable tape spring; Fiber-reinforced composite; Viscoelasticity; Aerospace Engineering; Flyg- och rymdteknik;

   Sammanfattning : In this thesis, experiments and simulations are performed to study the deployment dynamics of space webs and space booms, focusing on the deployment and stabilization phases of the space web and the behavior of the bi-stable tape spring booms after long-term stowage.The space web, Suaineadh, was launched onboard the sounding rocket REXUS-12 from the Swedish launch base Esrange in Kiruna on 19 March 2012.

3. 22. Governing street and market vending in Kitwe, Zambia : Shifting rationalities and vendors' individual and collective agency

   Författare :Lennert Jongh; Ilda Lindell; Andrew Byerley; Amin Kamete; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; urban informality; informal economy; street vendors; market vendors; vendors’ agency; urban space; collective organizing; vendors’ connections; gray spaces; government rationality; assemblage; Kitwe; Zambia; sub-Saharan Africa; Geography with Emphasis on Human Geography; geografi med kulturgeografisk inriktning;

   Sammanfattning : This thesis studies the governing of street and market vending in the Zambian city of Kitwe. Street and market vending has often been studied in relation to neoliberal urban developments. Such studies have shown how governing practices are driven by ambitions to create “world-class cities” and to attract (international) investment. LÄS MER

4. 23. Simulations of Semi-Crystalline Polymers and Polymer Composites in order to predict Electrical, Thermal, Mechanical and Diffusion Properties

   Författare :Fritjof Nilsson; Mikael Hedenqvist; Gerhard Goldbeck; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Several novel computer simulation models were developed for predicting electrical, mechanical, thermal and diffusion properties of materials with complex microstructures, such as composites, semi-crystalline polymers and foams. A Monte Carlo model for simulating solvent diffusion through spherulitic semicrystalline polyethylene was developed. LÄS MER

5. 24. Samtidens gränser : Om språkreformer och historisk tid runt sekelskiftet 1900

   Författare :Martin Jansson; Jenny Beckman; Petter Tistedt; Helge Jordheim; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; historical time; synchronisation; multiple temporalities; biblical criticism; phonetics; philology; translation; orthography; Idé- och lärdomshistoria; History of Sciences and Ideas;

   Sammanfattning : This dissertation examines two extensive language reforms that caused controversy and discord in late 19th century Sweden: a comprehensive spelling reform and a formally authorised Bible translation. Among the numerous disagreements and entanglements that afflicted the projects, one issue persisted more than any other: the question of historical time. LÄS MER

7. 25. Fritidshemmets matematik : Möten som räknas

   Författare :Anna Wallin; Paola Valero; Eva Norén; Hanna Palmér; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics education; school-age educare; enculturation; policy enactment; agential realism; mathemat-ing; Mathematics Education; matematikämnets didaktik;

   Sammanfattning : The aim of this thesis is to investigate mathematics in the context of Swedish extended education, namely, school-age educare. The research builds on investigating and identifying possible meanings of mathematics in school-age educare practice. LÄS MER
