  1. 1. The impact of CO2 fertilisation on foliage in West and East Africa

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Gaetane Demyttenaere; [2023]
    Nyckelord :Physical geography and ecosystem analysis; CO2 fertilisation; semi-arid ecosystems; remote sensing; Normalised Difference Vegetation Index; Earth and Environmental Sciences;

    Sammanfattning : Anthropogenic impact on terrestrial ecosystems continues to grow as we further enhance atmospheric Carbon Dioxide (CO₂) concentrations. The changing climatic conditions and direct influence of CO₂ on vegetation has a big impact on ecosystem functions. LÄS MER

  3. 2. Developing Extensions to the Walker-Unger Model in Consideration of the Panama Papers Leaks

    Kandidat-uppsats,

    Författare :Algot Delory; Tadas Matusevicius; [2023]
    Nyckelord :Money Laundering; Tax Haven; Panama Papers; Source and Host Countries; Walker-Unger Model;

    Sammanfattning : In 2016, the ICIJ independent organization released the leaks of the Panama Papers. Using the data presented, this thesis aims to evaluate and examine the models developed for the quantification of money laundering, analyze the variables that define the appeal of certain tax havens, and develop extensions to the Walker-Unger model.

  4. 3. Exchange Rate Analysis Between the U.S. Dollar and the Japanese Yen

    Kandidat-uppsats, Uppsala universitet/Statistik, AI och data science

    Författare :Yuta Sakiyama; [2023]
    Nyckelord :;

    Sammanfattning : The exchange data between the U.S. Dollar and Japanese Yen are analyzed with three models called the Auto-Regressive Integrated Moving- Average (ARIMA) model, the Generalized Auto-Regressive Conditional Heteroscedastic (GARCH) model, and the Fractional Differencing model.

  5. 4. Deep Neural Networks as SurrogateModels for Fuel Performance Codes

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Wenhan Zhou; [2023]
    Nyckelord :Transuranus; AI; Nuclear Fuel Rods;

    Sammanfattning : The core component of a nuclear power plant is the reactor and the fuel rods that supply it with fission fuel. Efficient and safe energy extraction is thus highly dependent on the reactor design and the conditions of the fuel rods. To anticipate high-quality operation and potential risks in advance, one must perform simulations on the fuel rods. LÄS MER

  7. 5. Assessment of the energetic feasibility of a novel CHP biorefinery concept

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Ângelo Miguel Mendes Ferreira; [2023]
    Nyckelord :biorefinery; bioenergy; biomimicry; combined heat and power; Earth Power Lodge; Technology and Engineering;

    Sammanfattning : This study investigates the potential for energetic self-reliance in an integrated biore- finery, the Earth Power Lodge (EPL), which aims to convert waste into valuable by- products through bio- and thermochemical conversion processes. The primary questions addressed include assessing the necessity of external propane to sustain the pyrolysis process and the net energy output of the ThermoChemical Reactor (TCR) process when fractional distillation is applied to the resulting bio-oils.
