  1. 1. Production of strangeness in partonic interactions at the LHC

    Författare :Oliver Matonoha; Partikel- och kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; quantum chromodynamics; quark-gluon plasma; neutral strange particles; small systems; transverse spherocity; underlying event; Fysicumarkivet A:2023:Matonoha;

    Sammanfattning : The strong interaction is responsible for nearly all observable baryonic matter in the Universe. Quantum Chromodynamics, which describes interactions between quarks and gluons, however, cannot be solved analytically in the non-perturbative regime, involving low momentum transfers. LÄS MER

  3. 2. Deep learning for news topic identification in limited supervision and unsupervised settings

    Författare :Arezoo Hatefi; Frank Drewes; Johanna Björklund; Xuan-Son Vu; Eric Gaussier; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Topic Identification; Data Clustering; News Stream Clustering; Semi-Supervised Learning; Unsupervised Learning; Event Topics; News Stories; Multimodal News; Document Classification; Document Clustering; Deep Learning; Deep Clustering; Pre-trained Language Models;

    Sammanfattning : In today's world, following news is crucial for decision-making and staying informed. With the growing volume of daily news, automated processing is essential for timely insights and in aiding individuals and corporations in navigating the complexities of the information society.

  4. 3. The Effect of Different Perturbations on the Stability Analysis of Light Water Reactors

    Författare :Victor Dykin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; BWR and PWR stability; stability indicators; propagating density perturbation; autocorrelation function; density wave oscillations; decay ratio; non-white driving force; damped harmonic oscillator; reduced order models; Green s function technique;

    Sammanfattning : Neutron noise analysis techniques are studied and developed, with primary useof determining the stability of Boiling Water Reactors (BWRs). In particular, the role ofa specific perturbation prevailing in Light Water Reactors, the propagating densityperturbation, in the stability of BWRs and on the noise field of LWRs in general, isinvestigated by considering three topics.

  5. 4. Sustained and triggered release by microencapsulation

    Författare :Viktor Eriksson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; cellulose; controlled release; microencapsulation; solution blown;

    Sammanfattning : Uncontrolled growth of microorganisms is problematic in areas ranging from wound care to aquaculture and ship hulls. In chronic and hard-to-heal wounds, a bacterial biofilm can impair wound healing. LÄS MER

  7. 5. Th Dynamics of Star Cluster Formation

    Författare :Juan Pablo Farias Osses; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Star Formation; Star Clusters; Stellar Dynamics;

    Sammanfattning : A major question in astrophysics is how star clusters form. These objects are important, since they are the birth sites of most stars, perhaps including our own Sun. LÄS MER
