1. 6. Construction of Adaptive Multistep Methods for Problems with Discontinuities, Invariants, and Constraints

   Författare :Fatemeh Mohammadi; Numerisk analys; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multistep methods; Initialization; beta-blocking; Discontinuity; Time adaptivity; Strong stability preserving; Differential algebraic equations;

   Sammanfattning : Adaptive multistep methods have been widely used to solve initial value problems. These ordinary differential equations (ODEs) may arise from semi-discretization of time-dependent partial differential equations(PDEs) or may combine with some algebraic equations to represent a differential algebraic equations (DAEs).

3. 7. Desire Lines : Towards a Queer Digital Media Phenomenology

   Författare :Matilda Tudor; Stina Bengtsson; Sharif Mowlabocus; Södertörns högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; digital media; queer; Russia; phenomenology; space; time; mobility; visibility; embodiment; discontinuity; Hornet; Growlr; VKontakte; Mamba; digitalt mediebruk; queer; Ryssland; fenomenologi; tid och rum; mobilitet; synlighet; kroppslighet; diskontinuitet; Hornet; Growlr; Vkontakte; Mamba; Kritisk kulturteori; Critical and Cultural Theory; Östersjö- och Östeuropaforskning; Baltic and East European studies;

   Sammanfattning : This dissertation explores ways in which “queer digital media use” co-produces senses of space, time, and queer being in contemporary Russia. Considering the particular implications of (in)visibility for queer living, and the importance of compartmentalizing conflicting spheres, the study provides a grounded account of queer life lived with and through digital media in a context currently characterized by “anti-gay” sentiments.

4. 8. Muntlighet och minne : Sagatraditionen, kulturhistorien och det kulturella minnets blinda fläck

   Författare :Frederik Wallenstein; Peter Jackson Rova; Birgitta Svensson; Stephen Mitchell; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Cultural memory; collective memory; Assmann; cultural forgetting; continuity; discontinuity; culture; tradition; memory; collective relevance; oral prose; oral tradition; Icelandic sagas; soul conceptions; Old Norse religion; draugar; History of Religion; religionshistoria;

   Sammanfattning : This dissertation focuses on two distinct areas of study that do not have a predetermined or necessary connection to each other. The first area concerns issues of more immediate relevance to the cultural history of the Icelandic sagas, whereas the second area concerns issues of more general relevance to cultural memory research (Cultural Memory Studies, Kulturelles Gedächtnis) and what the author perceives as a deficiency or “blind spot” in this theory.

5. 9. Design and verification of discontinuity regions in reinforced concrete structures with the strut and tie method : Stress redistribution due to cracking and plastic deformation

7. 10. On the Modelling of Fracture Using Strong Discontinuities

   Författare :Martin Fagerström; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fracture; strong discontinuity; material forces; finite deformations; FEM;

   Sammanfattning : The major concern of this work is the constitutive and numerical modelling of fracture,based on strong discontinuity formulations. More particularly, an extended finiteelement approach is used, where the total displacement is separated in two mutuallyindependent fields, representing the continuous and discontinuous displacement respectively.
