  3. 12. Movement patterns and displacement of a soil insect

    Författare :Elna Nilsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; attraction; repellence; fatty acid; Ecology; Ekologi; alarm; autoregressive model; autocorrelation; random walk; Protaphorura armata; Collembola; migration; dispersal; movement; displacement;

    Sammanfattning : Movement and dispersal are important determinants of the spatial distribution and persistence of animal populations in a heterogeneous environment. I studied the small-scale movement pattern of a soil-living insect, Protaphorura armata (Collembola) by using a video-equipment. LÄS MER

  7. 15. Simulation of diffusional processes in alloys : techniques and applications

    Författare :Henrik Strandlund; John Ågren; John Morral; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diffusion; Kirkendall effect; Phase transformations; Random walk; Solute drag; Interfacial mobility; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : This thesis concerns computer simulation of diffusional processes in alloys. The main focus is on the development of simulation techniques for diffusion in single-phase domains, but also diffusion controlled phase-transformations and interfacial processes are discussed. LÄS MER
