  3. 2. Thermochemical energy utilization of biomass in Rwanda - a screening of potential feedstocks

    Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Felix Johansson Carne; [2022]
    Nyckelord :bioenergy; agricultural; residues; waste; agroforestry; africa; energiteknik; bioenergi; jordbruksrester; afrika; termokemisk; bränslen;

    Sammanfattning : Traditional bioenergy practices in sub-Saharan Africa involve collecting natural forest wood and burning it in simple fireplaces for household cooking. This is actually still very common, especially in rural areas. The situation is unfortunately connected to health issues, inequality and natural forest degradation and deforestation. LÄS MER

  4. 3. Improving Queuing Time in a Pull Based Containerized Continuous Integration Build System

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Catalin Gangalic; [2021]
    Nyckelord :Distributed Systems; Kubernetes; Time Series; Builds Systems; Continuous Integration; Distribuerade System; Kubernetes; Tidsserier; Bygger System; Kontinuerlig Integration;

    Sammanfattning : Most of the medium and big size software companies around the world are now using some form of continuous automatic build systems, with smaller companies following through. This approach, towards a more continuous flow, has pushed for more innovation in the domain and the adoption of various orchestration tools for these builds. LÄS MER

  5. 4. Investigating the efficient markethypothesis using Fourier analysis

    Kandidat-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :David Fang; [2019]
    Nyckelord :Efficient Markets; Calendar effects; Seasonalities; Fourier analysis; Spectral analysis; Business and Economics;

    Sammanfattning : This study examines if the Swedish stock market adheres to the weak form efficient market hypothesis using Fourier analysis on past stock prices to identify possible cyclic returns. Fourier analysis is well suited for finding seasonalities which would violate the weak-form efficiency. LÄS MER

  7. 5. Modelling Seasonalities of HPFCs Using a Parametric Approach

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Reza Rastegar; Lucas Svantesson; [2019]
    Nyckelord :Power Markets; Hourly Price Forward Curves; Seasonality; Electricity Spot Price; Mathematics and Statistics;

    Sammanfattning : Electricity differs from other commodities in that it cannot be stored. This non-storability characteristic results in traditional pricing methods for commodities not being applicable for electricity. An alternative pricing method is therefore needed and the solution is the Hourly Price Forward Curve (HPFC). LÄS MER
