1. 6. Automatic memory management for flexible real-time systems

   Författare :Sven Robertz; Institutionen för datavetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; feedback scheduling; embedded systems; real-time; memory management; garbage collection; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll;

   Sammanfattning : In a flexible real-time system, the constraints in available CPU time and memory lead to resource management problems, which must be handled carefully in order to maximize quality of service while avoiding overload. Managing CPU time -- scheduling -- is well studied and dynamic scheduling is widely accepted in the real-time industry. LÄS MER

3. 7. Becoming a professional : A longitudinal study of graduates'  professional trajectories from higher education to working life

   Författare :Sofia Nyström; Lars Owe Dahlgren; Madeleine Abrandt Dahlgren; Lennart Svensson; Linköpings universitet; []
   Nyckelord :longitudinal study; qualitative analysis; profesional development; identity; employability; higher education; work life; community of practice; gender; Longitudinell studie; kvalitativ analys; professionell utveckling; identitet; anställningsbarhet; högre utbildning; arbetsliv; praktikgemenskap; genus; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

   Sammanfattning : The study has a longitudinal design where Political Science and Psychology graduates’ have been interviewed on three consecutive occasions; the last semester before graduation, the first year and then, in the third year of professional work. The theoretical frame of reference comprises a situated and social learning theory and a gender perspective. LÄS MER

4. 8. Models for analysis of shotcrete on rock exposed to blasting

   Författare :Lamis Ahmed; Anders Ansell; Erik Nordström; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shotcrete; Rock; Vibration; Stress waves; Numerical analysis.; Sprutbetong; Berg; Vibrationer; Spänningsvågor; Numerisk analys.;

   Sammanfattning : In underground construction and tunnelling, the strive for a more time-efficient construction process naturally focuses on the possibilities of reducing the times of waiting between stages of construction. The ability to project shotcrete (sprayed concrete) on a rock surface at an early stage after blasting is vital to the safety during construction and function of e. LÄS MER

5. 9. Reconciling gene family evolution and species evolution

   Författare :Joel Sjöstrand; Jens Lagergren; Nicolas Lartillot; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational biology; Bioinformatics; Phylogenetics; Phylogenomics; Comparative genomics; Evolutionary biology; datalogi; Computer Science;

   Sammanfattning : Species evolution can often be adequately described with a phylogenetic tree. Interestingly, this is the case also for the evolution of homologous genes; a gene in an ancestral species may – through gene duplication, gene loss, lateral gene transfer (LGT), and speciation events – give rise to a gene family distributed across contemporaneous species.

7. 10. Water diffusion and free volume in hydrophilic polymers

   Författare :Charlotte Trotzig; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; free volume; self-diffusion; degree of crystallinity; glass transition temperature; tensile storage modulus; surface tension; isotherm; HPMC; PEO; water; triacetin; clay; Macromolecular chemistry; dynamic mechanical analysis; Fysikalisk kemi; differential scanning calorimetry; nuclear magnetic resonance; positron annihilation; Makromolekylär kemi;

   Sammanfattning : During moisture uptake in polymers, the diffusion of the water molecules is believed to occur via unoccupied voids. These voids are called free volume cavities and their sizes are continuously altered when the moisture content in the polymer is enhanced. LÄS MER
