2. 1. Finite Element Modelling of Fluid-Structure Interaction

   Author : Göran Sandberg; Byggnadsmekanik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Element Method; Coupled problem; fluid-structure interaction; Transient; Acoustics; Caviation; Time Stepping; Symmetric; Nonlinear acoustics; Submerged structures; finite element method; Coupled problem; Fluid-structure interaction; Transient; Acoustics; Cavitation; Time Stepping; Symmetric; Nonlinear acoustics; Submerged structures;

   Abstract : The dynamic interaction between non-viscid, compressible fluid and an elastic structure is studied. Finte element formulations, using the weighted residual method, are derived. Different primary variables in the fluid domain are used and different source functions are considered. READ MORE

4. 2. Observing Lyman alpha emitters - How does Lyman alpha escape from galaxies?

   Author : Andreas Sandberg; Göran Östlin; Lucia Guaita; Matthew Hayes; Caryl Gronwall; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; astronomi;

   Abstract : The Lyman alpha (Lyα) emission line has grown to become one of the most successful tools for finding galaxies at high redshift. At redshifts corresponding to the early cosmic times of reionization and primeval galaxy formation, the wavelength of Lyα is still accessible with ground-based facilities. READ MORE

5. 3. Process intensification in mechanical pulping : Reduced process complexity and improved energy efficiency

   Author : Christer Sandberg; Per Engstrand; Jan-Erik Berg; Göran Bengtsson; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This work shows that, for newsprint quality grades, the production processes for mechanical pulp can be simplified, and the specific electrical energy demand can be reduced with around 600 kWh/ton (30%). The purpose of the work is to demonstrate how the production cost for mechanical pulps can be decreased through increased energy efficiency and reduced number of unit operations. READ MORE

6. 4. They Did IT : The Formation and Organisation of Interactive Media Production in Sweden

   Author : Fredrik Augustsson; Göran Ahrne; Åke Sandberg; Knut Holtan Sørensen; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; interactive media; Internet; IT; division of labour; organisation; production; social field; critical realism; Sociology; Sociologi;

   Abstract : The overall aim of the study is to describe and explain the formation and organisation of interactive media production in Sweden from the 1990s to the end of 2003, the period of the so-called IT boom and crash, through the development of a theoretical model and gathering of empirical material.In the theory, interactive media production is conceptualised as a practice in part taking place on a social field structured according to the division and integration of labour within and between firms, and logics and status.

7. 5. Structural-acoustic analysis of wall-to-floor joints in timber-framed housing

   Author : Åsa Bolmsvik; Torbjörn Ekevid; Göran Sandberg; Växjö universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik; Building engineering; Byggnadsteknik; Byggteknik; Civil engineering;

   Abstract : Even though a building meets the regulations with respect to impact sound, structures with wooden frames may receive complaints from the inhabitants due to structure-borne sound in the lower frequencies. In this thesis measuring methods that are more precise than the traditional measuring methods have been used to see if they could give a better knowledge about flanking transmission in the low frequencies in timber-framed structures.
