  1. 1. Torkstress hos urbana träd i Göteborg: Effekter av låg vattentillgång under torkan 2018

    Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Andrea Sartorius; [2023-10-27]
    Nyckelord :;

    Sammanfattning : During late spring and most of the summer in the year of 2018 the weather in Sweden was more extreme than normal, with high temperatures and few rainfalls. This resulted in a drought, of which the effects were noticed all over the country. One of the noticeable effects was an earlier leaf abscission from trees. LÄS MER

  3. 2. Estimating historic ranges of extinct scavenging birds from North America during the late Pleistocene using co-occurrence data from the fossil record

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Melissa Miranda; [2023-06-30]
    Nyckelord :Scavenging birds; Vultures; Co-occurrence Data; Range Estimates; Spatial Autoregressive Models; Co-extinction;

    Sammanfattning : The aim of my study was to estimate and compare the historic range of nine scavenging birds from North America that went jointly extinct with their mammalian megafaunal prey in the Late Pleistocene. Although the severity and timing of their co-extinction are strongly correlated, there has been little analytical support in providing estimates for the possible geographic distribution of scavenging birds prior to the extinction event.

  4. 3. Finding ways of optimizing coagulant dosage, for a more sustainable wastewater treatment process

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Hanna Sjöman; [2023]
    Nyckelord :Wastewater treatment process; coagulant dosage; COD; machine learning; water and environmental engineering; Technology and Engineering;

    Sammanfattning : The wastewater treatment process at Oatly consists of several treatment steps of which, two are chemical treatment steps involving coagulation followed by flotation to remove phosphorous and COD. The coagulant dosage is mainly determined based on the operator’s experience and supported using results from jar tests. LÄS MER

  5. 4. Improved Statistical Methods for Elliptic Stochastic Homogenization Problems : Application of Multi Level- and Multi Index Monte Carlo on Elliptic Stochastic Homogenization Problems

    Kandidat-uppsats, Uppsala universitet/Tillämpad beräkningsvetenskap

    Författare :Khalil Daloul; [2023]
    Nyckelord :Homogenization; Multilevel Monte Carlo; Multi-Index Monte Carlo; Monte Carlo; Multiscale methods;

    Sammanfattning : In numerical multiscale methods, one relies on a coupling between macroscopic model and a microscopic model. The macroscopic model does not include the microscopic properties that the microscopic model offers and that are vital for the desired solution. LÄS MER

  7. 5. Interpreting Sensitivity

    Master-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Charlie Nilsson; [2023]
    Nyckelord :excess sensitivity; comovement; non-Ricardian households; liquidity constraints; retirement puzzle; Business and Economics;

    Sammanfattning : The standard interpretation of aggregate excess sensitivity is that it represents the economy share of non-Ricardian households. However, household level evidence suggests that excess sensitivity can also be explained by the comovement of consumption and income over the lifetime, which occurs due to retirement and changes in household size.
