1. 1. Concrete Structures Subjected to Blast and Fragment Impacts - Numerical Simulations of Reinforced and Fibre-reinforced Concrete

   Författare :Ulrika Nyström; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SDOF; Concrete; fragment impact; weapon effects; fibre-reinforced concrete; blast wave; numerical simulations; reinforced concrete;

   Sammanfattning : Concrete is widely used in design of protective structures due to its good energy-absorbing characteristics under high pressures and, when properly reinforced, ductile behaviour. Nevertheless, the response of concrete structures subjected to severe dynamic loading differs from their static behaviour, on a structural level but also on a material level. LÄS MER

3. 2. Advanced Fluid-Structure Interaction Modelling and Simulation for Aerospace Applications

   Författare :Stefan Nilsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aeroacoustics; Hybrid RANS-LES; CSD; cavity flow; aeroelastics; CFD; FSI;

   Sammanfattning : Numerical fluid-structure interaction (FSI) methods for the prediction of aeroelastic phenomena are important within aerospace. The continuous development of computer technologies has enabled the use of more advanced FSI methods. The use of advanced methods has the potential to provide more accurate predictions. LÄS MER

4. 3. Group membership and eyewitness testimony

   Författare :Torun Lindholm; Jerry Shaw; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Eyewitness testimony; group membership; intergroup biases; memory performance; psykologi; Psychology;

   Sammanfattning : The present thesis includes four empirical studies that explore whether eyewitness accounts of a violent crime may be affected by factors related to the group membership of witness, perpetrator, and victim.Study 1 investigates how an immigrant and a Swedish perpetrator of a simulated, violent robbery are evaluated and remembered by immigrant and Swedish witnesses.

5. 4. Warhead penetration in concrete protective structures

   Författare :Håkan Hansson; Anders Ansell; Mattias Unosson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Warhead penetration; FE analysis; experiment; material modelling; fortifications; Stridsdelspenetration; FE-analyser; experiment; materialmodellering; fortifikationer;

   Sammanfattning : The analysis of penetration of warheads in concrete protective structures is an important part of the study of weapon effects on protective structures. This type of analysis requires that the design load in the form of a warhead is determined, and its characteristic and performance within a protective structure is known. LÄS MER

7. 5. Promise, Protection, and Prosperity. Aspects of the "Shield" as a Religious Relational Metaphor in an Ancient Near Eastern Perspective. An Iconographical and Textual Analysis

   Författare :Arne Wiig; Centrum för teologi och religionsvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; Theology; Assyria; Egypt; Hebrew Bible; Ancient Near East; relational metaphor; shield metaphor; Metaphor theory; shield; Teologi;

   Sammanfattning : This thesis discusses the religious metaphorical use of different words for "shield" in the Hebrew Bible and Egyptian and Assyrian literature. The literary contexts in the analysis are delimited based on the observation that they share a similar view of divine intervention in war and an analogous view of the enemy. LÄS MER
