  1. 11. The Impact of Weather on Residential Fires in Sweden: A Regression Analysis

    Kandidat-uppsats, KTH/Matematisk statistik; KTH/Matematisk statistik

    Författare :Viktor Reineck; Folke Ulfsparre; [2019]
    Nyckelord :Regression; Poisson; Negative binomial; Generalized linear models; Organizational theory; Regression; Poisson; Negativ binomial; Generaliserade linjära modeller; Organisationsteori;

    Sammanfattning : The purpose of this report is to investigate possible relationships between the number of residential fires in Sweden and various weather parameters. The study is conducted based on a hypothesis as stated by the MSB, the Swedish Civil Contingencies Agency, that behavioral factors related to weather can have an influence on the number of residential fires.

  2. 12. Hållbar boskapsproduktion : växthusgaser från nötkreatur och möjliga strategier för minskade utsläpp

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Julia Bonevik; [2019]
    Nyckelord :koldioxid; lustgas; metan; silvopastoral; ekologisk;

    Sammanfattning : Hållning av nötboskap genererar utsläpp av de tre växthusgaserna koldioxid, lustgas och metan. Alla tre har stor betydelse för klimatet på jorden då de bidrar till den pågående globala uppvärmningen. Utsläpp från dessa växthusgaser kan delas in de som kommer direkt ur korna samt indirekta utsläpp som genereras vid skötseln av dem. LÄS MER

  3. 13. Influence of Nucleation Techniques on the Degree of Supercooling and Duration of Crystallization for Sugar Alcohol as Phase Change Material : Investigation on erythritol-based additiveenhanced Composites

    Master-uppsats, KTH/Energiteknik; KTH/Energiteknik

    Författare :JiaCheng Lin; HaoRan Teng; [2019]
    Nyckelord :Phase Change Material; Latent Thermal Energy Storage; Temperature-history; Sugar Alcohols; Supercooling; Duration of crystallization; Crystallization; Solidification; Fasändringsmaterial; Latent Termisk Energilagring; T-history; Sockeralkoholer; Underkylning; Varaktighet av kristallisering; Kristallisering; Stelning;

    Sammanfattning : Utilizing Phase Change Materials (PCM) for Latent Thermal Energy Storage (LTES) applications have previously been extensively researched as a measure to reduce greenhouse gas emissions from energy consumption. In order to make use of the waste heat from industrial processes for LTES purposes, a new demand emerged for PCMs capable of phase change in mid-temperature ranges of 100 °C - 200 °C. LÄS MER

  4. 14. Steaming of Wood Chips - Experimental determination of heating times and effect of different parameters

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Henrik Broberg; [2019]
    Nyckelord :;

    Sammanfattning : The presteaming of wood chips is an important step in the chemical pulping industry. It removes the air from within wood chips, allowing the cooking liquor to better impregnate wood chips, which leads to a more uniform cooking process, and lowers the amount of rejects. LÄS MER

  5. 15. Studies of Possible QGP Estimators in proton-proton Collisions

    Master-uppsats, Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Författare :Anna Önnerstad; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : This thesis presents studies of three different Quark-Gluon Plasma estimators in proton-proton collisions using what is currently believed to be quark-gluon plasma observables; radial flow, elliptic flow and strangeness enhancement. The three tested estimators were Transverse Spherocity, an altered version of Transverse Spherocity where all p_T was put to one, and a newly developed estimator called Mid-Forward. LÄS MER
