2. 1. Systematic planning and execution of finite element model updating

   Author : Joakim Wallin; Costin Pacoste; Raid Karoumi; Mario Plos; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamics; finite element model updating; bridge; objective function; updating parameter; mode pairing; dynamik; finita element modelluppdatering; bro; målfunktion; uppdateringsparameter; matchning av moder; Civil and Architectural Engineering; Byggvetenskap;

   Abstract : In design of bridges and for estimation of dynamic properties and load carrying capacity Finite Element Method (FEM) is often used as a tool. The physical quantities used in the Finite Element (FE) model are often connected to varying degrees of uncertainty. READ MORE

4. 2. Train your brain : updating, transfer, and neural changes

   Author : Erika Dahlin; Lars Nyberg; Anna Stigsdotter Neely; Torkel Klingberg; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cognitive training; executive functioning; transfer; fMRI; brain system; young adults; elderly; practice; neural correlates; individual differences; Experimental brain research; Experimentell hjärnforskning; Cognitive science; Kognitionsforskning; fysiologi; Physiology;

   Abstract : An initial aim of this thesis was to determine whether training of a specific executive function (updating) produces improvements in performance on trained and transfer tasks, and whether the effects are maintained over time. Neural systems underlying training and transfer effects were also investigated and one question considered is whether transfer depends on general or specific neural overlap between training and transfer tasks.

5. 3. Railway bridge response to passing trains : Measurements and FE model updating

   Author : Johan Wiberg; Raid Karoumi; Lennart Elfgren; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

   Abstract : Today’s railway bridges are analysed in more detail for moving loads due to the increase in speeds and axle loads. However, these numerical analyses are very time consuming as they often involve many simulations using different train configurations passing at different speeds and many considerations to take into account.

6. 4. Exploring Cognitive Spare Capacity : Executive Processing of Degraded Speech

   Author : Sushmit Mishra; Mary Rudner; Stefan Stenfelt; Jerker Rönnberg; Thomas Lunner; Mithell S. Sommers; Linköpings universitet; []
   Keywords : Working memory; cognitive spare capacity; updating; inhibition; Arbetsminne; kognitiv reservkapacitet; uppdatering; inhibition;

   Abstract : Cognitive resources, specifically working memory capacity are used for listening to speech, especially in noise. Cognitive resources are limited, and if listeners allocate a greater share of these resources to recovering the input signal in noise, fewer resources are available for interpreting and encoding its linguistic content.

7. 5. Dynamic characteristics of automobile exhaust system components

   Author : Thomas Englund; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Correlation; Exhaust system; Experimental investigation; Finite element model; Flexible joint; Modal analysis; Non-linear; Simplified modelling; Structural dynamics; Updating;

   Abstract : Demands on emission control, and low vibration and noise levels have made the design of automobile exhaust systems a much more complex task over the last few decades. This, combined with increasing competition in the automobile industry, has rendered physical prototype testing impractical as the main support for design decisions. READ MORE
