  1. 1. Nuclear fission and fusion in a random-walk model

    Författare :Martin Albertsson; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fission; Brownian shape motion; energy partition; neutron multiplicity; kinetic energy; fusion; superheavy elements; quasifission; Fysicumarkivet A:2021:Albertsson;

    Sammanfattning : This dissertation deals with theoretical descriptions of nuclear fission and synthesis of superheavy elements via fusion. The associated shape evolutions are treated using a random-walk approach where both the potential energy and the nuclear level density influence the dynamics. LÄS MER

  3. 2. Abatement of Chromium Emissions from Steelmaking Slags - Cr Stabilization by Phase Separation

    Författare :Galina Albertsson; Lidong Teng; Seshadri Seetharaman; Voicu Brabie; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spinel; slag basicity; oxygen partial pressure; chromium oxide vaporization; шпинель; шлак; парциальное давление кислорода; испарение оксидa хрома; 尖晶石; 炉渣碱度; 氧分压; 铬氧化物汽化; spinell; slaggbasicitet; syrepartialtryck; förångning av kromoxid;

    Sammanfattning : Chromium is an important alloying element in stainless steel but also environmentally harmful element. A number of mineralogical phases present in the slag matrix can contain chromium and lead to chromium leaching. LÄS MER

  4. 3. Impact and control of weeds in biomass willow clones

    Författare :Johannes Albertsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Willow (Salix spp.) grown on arable land as short-rotation coppice (SRC) produces renewable energy in the form of woody biomass. This perennial crop has a high ratio of energy output to input and a good environmental profile. However, weed control is mostly dependent on herbicide use. LÄS MER

  5. 4. Machine Learning in High-Energy Physics: Displaced Event Detection and Developments in ROOT/TMVA

    Författare :Kim Albertsson; Fredrik Sandin; Andreas Hocker; Tobias Golling; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cyber-Physical Systems; Cyberfysiska system;

    Sammanfattning : Many proposed extensions to the Standard Model of particle physics predict long-lived particles, which can decay at a significant distance from the primary interaction point. Such events produce displaced vertices with distinct detector signatures when compared to standard model processes. LÄS MER

  7. 5. Superconformal D-branes and moduli spaces

    Författare :Cecilia Albertsson; Eric Bergshoeff; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Theoretical Physics; teoretisk fysik;

    Sammanfattning : The on-going quest for a single theory that describes all the forces of nature has led to the discovery of string theory. This is the only known theory that successfully unifies gravity with the electroweak and strong forces. LÄS MER
