1. 6. Theoretical studies of Membrane Proteins : Properties, Prediction Methods and Genome-wide analysis

   Författare :Erik Wallin; David Jones; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biology; Biochemistry; Biokemi;

   Sammanfattning : Membrane proteins are a large and important class of proteins. They are responsible for several of the key functions in a living cell, e.g. transport of nutrients and ions, cell-cell signaling, and cell-cell adhesion. LÄS MER

3. 7. Process Integration of Industrial Heat Pumps in Grass-Root and Retrofit Situations

   Författare :Erik Wallin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; pinch technology; retrofit; industrial heat pumps; grass-root;

   Sammanfattning : In several works, methods for process integration of heat pumps (HPs) have been developed, which in turn have been used for case studies in different industrial types. HP integration has thus proven to be a promising technique for utility savings and attractive payback periods. LÄS MER

4. 8. Exploiting data locality in adaptive architectures

   Författare :Dan Wallin; Erik Hagersten; Sverker Holmgren; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Systems; Datorteknik;

   Sammanfattning : The speed of processors increases much faster than the memory access time. This makes memory accesses expensive. To meet this problem, cache hierarchies are introduced to serve the processor with data. However, the effectiveness of caches depends on the amount of locality in the application's memory access pattern. LÄS MER

5. 9. Individual Information Adaptation Based on Content Description

   Författare :Erik Oskar Wallin; KTH; []
   Nyckelord :metadata; semantic web; personalization; information adaptation; one-to-one marketing; evaluation; optimization; personification; customization; individualization; internet; content filtering; automation;

   Sammanfattning : Today’s increasing information supply raises the needfor more effective and automated information processing whereindividual information adaptation (personalization) is onepossible solution. Earlier computer systems for personalizationlacked the ability to easily define and measure theeffectiveness of personalization efforts. LÄS MER

7. 10. Pushing methods for plasma simulations into the QED regime

   Författare :Erik Karl Wallstén Wallin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LWFA; nonlinear dynamics; plasma; Manley-Rowe; particle-in-cell; synchrotron radiation; radiation reaction;

   Sammanfattning : The interaction between a super-intense laser pulse, with intensity up to 10²² W/cm², and a plasma opens new regimes of physics, with new questions and more demand on existing numerical tools. Relativistic and quantum effects which are negligible for lower laser intensities become important and must be properly modelled to generate reliable predictions. LÄS MER
