1. 6. Uncertainty in Sliding Stability Analyses of Existing Concrete Gravity Dams with Bonded Concrete-Rock Interfaces

   Författare :Alexandra Krounis; Stefan Larsson; Fredrik Johansson; Jonny Sjöberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Safety assessment of existing dams becomes more and more important with their increasing age. In addition, new regulations, due to climate changes and changes in knowledge, demand a re-evaluation of the existing dams’ safety. LÄS MER

   Författare :Aseem Salhotra; Alf Månsson; Henry Hess; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; biocomputation; molecular motors; 3-SAT; surface chemistry; actomyosin; actin; myosin II; heavy meromyosin; myosin XI; engineered myosin; in vitro motility assay; nanofabrication; alternate computing; network based biocomputation; protein-surface interaction; longevity; prolongation; surface recycling; affinity purification; blocking actin; Bioteknik; Biotechnology; Biokemi; Biochemistry;

   Sammanfattning : There exist complex mathematical problems that are important in real world applications such as weather prediction, molecular modelling, network route optimization and more. In general, such problems are solved using supercomputers with higher computing efficiency but this also consumes high energy along with high production and maintenance cost. LÄS MER

4. 8. Tribology of Carbon Based Coatings for Machine Element Applications

   Författare :Fredrik Svahn; Åsa Kassman-Rudolphi; Sture Hogmark; Mats Larsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Sammanfattning : Demands on lower fuel consumption, reduced pollution, increased operating times, etc. force the automotive industry to constantly improve the performance of critical machine elements. In this development various carbon based coatings have proven very promising, mainly because of their low friction and high wear resistance in dry sliding contacts. LÄS MER

5. 9. Reconfigurable-Hardware Accelerated Stream Aggregation

   Författare :Prajith Ramakrishnan Geethakumari; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stream; Reconfigurable Computing; Aggregation; Dataflow; FPGA; Memory Hierarchy; Compression;

   Sammanfattning : High throughput and low latency stream aggregation is essential for many applications that analyze massive volumes of data in real-time. Incoming data need to be stored in a single sliding-window before processing, in cases where incremental aggregations are wasteful or not possible at all. LÄS MER

7. 10. The influence of microstructure on mechanical and tribological properties of lamellar and compacted irons in engine applications

   Författare :Rohollah Ghasemi; Anders E. W. Jarfors; Ricardo César Dommarco; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast iron; Si solution-strengthened CGI; microstructure; mechanical properties; modelling and simulation; tribology; abrasive wear; scratch testing;

   Sammanfattning : Lamellar graphite iron (LGI) is commonly used in diesel engine applications such as piston rings–cylinder liner where an excellent combination of physical and tribological properties is essential to avoid scuffing and bore polishing issues. The excellent tribological behaviour of LGI alloys is related to the graphite lamellas, which act as solid lubricant agents by feeding onto the tribosurfaces under sliding conditions. LÄS MER
