2. 1. Framing The Israel/Palestine Conflict in Swedish History School Textbooks

   Author : Michael Walls; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Abstract : The following dissertation has examined the ways in which the history of the Israel/Palestine conflict has been framed in a number of Lower Secondary school Swedish History textbooks as well as in a small number of Social Science/Civics teachers’ statements. The initial problem discussed has been a noted discrepancy between textbook content and scholarship on the conflict’s history. READ MORE

4. 2. FRCM-Composites for Strengthening Concrete Walls with Openings : Experimental and Numerical Analysis

   Author : Cristian Sabau; Björn Täljsten; Thomas Blanksvärd; Gabriel Sas; Cosmin Popescu; Thanasis C. Triantafillou; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FRCM; reinforced concrete; walls; openings; strenghtening; Structural Engineering; Konstruktionsteknik;

   Abstract : Upgrading existing buildings to new functional requirements may require new openings that can weaken the structure, prompting the need for strengthening. In such cases, traditional strengthening solutions, such as creating a reinforced concrete or steel frame around the opening, imply long-term restrictions in the use of the structure. READ MORE

5. 3. Thermal Modeling of Walls, Foundations and Whole Buildings Using Dynamic Thermal Networks

   Author : Eva-Lotta Wentzel; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; walls; weighting functions; Dynamic thermal networks; building; dynamic heat conduction; foundation; step-response functions;

   Abstract : The modeling of the energy balance of buildings is a major task in building physics. A new theory called dynamic thermal networks is under development at the Building Physics Research Group at Chalmers. The calculations are based on step-response functions, and the problems are illustrated in so-called dynamic networks. READ MORE

6. 4. Shear walls for multi-storey timber buildings

   Author : Johan Vessby; Hilmer Riberholt; Växjö universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-storey structures; timber engineering; wind stabilization; shear walls; cross-laminated timber wall panels; fasteners; connections; sheathing; Building engineering; Byggnadsteknik; Byggteknik; Civil engineering;

   Abstract : Wind loads acting on wooden building structures need to be dealt with adequately in order to ensure that neither the serviceability limit state nor the ultimate limit state is exceeded. For the structural designer of tall buildings, avoiding the possibly serious consequences of heavy wind loading while taking account at the same time of the effects of gravitation can be a real challenge.

7. 5. Turbulent flows over permissive boundaries and porous walls

   Author : Seyed Morteza Habibi Khorasani; Shervin Bagheri; Geert Brethouwer; Alfredo Soldati; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Direct numerical simulations; wall-bounded turbulence; flow control; porous walls; heat transfer; Direkta numeriska simuleringar; väggbunden turbulens; flödeskontroll; porösa väggar; värmeöverföring; Teknisk mekanik; Engineering Mechanics;

   Abstract : This thesis investigates how in wall-bounded turbulent flows changes to the wall can induce changes in the flow. To this end, we investigate the use of wall boundary conditions meant to mimic the effect of textured surfaces. READ MORE
