  1. 21. Eye-Movement Correlates of Pattern Separation in a Mnemonic Similarity Task Modified with Naturalistic Scenes

    Master-uppsats, Lunds universitet/Institutionen för psykologi

    Författare :Ecem Dilmaç; [2023]
    Nyckelord :Scanpath Similarity; Mnemonic Similarity Task; Episodic Memory; Lure Discrimination; MultiMatch; Real-World Visual Search; Encoding; Retrieval; Social Sciences;

    Sammanfattning : Pattern separation is one of the central operations of episodic memory. Tasks that evaluate the pattern separation usually base their assessments on the behavioral recall of simple objects or words and are far from real-life experiences and daily memory performance. Thus, typical tasks that assess pattern separation lack ecological validity. LÄS MER

  3. 22. Olika ekonomiska faktorers betydelse vid investering av solceller kopplat till fjäderfäproduktion : analys av ekonomiska faktorer

    Kandidat-uppsats, SLU/Dept. of People and Society

    Författare :Nils Carlsson; Viktor Närkeby; [2023]
    Nyckelord :Solceller; ekonomi; faktorer; fjäderfä;

    Sammanfattning : Med en ostabil och fluktuerande energimarknad som i sin tur generar en osäker elprismarknad med extrema prisökningar över hela landet gör att ett ökat intresse finns för att investera i solcellsanläggningar i Sverige, speciellt för företag med stort behov av el. Fjäderfäproducenter är en av de branscher som fått se stora elkostnadsökningar då de ofta har ett stort behov av el. LÄS MER

  4. 23. Ecological risk assessment of pesticide use in rice farming in the Mekong Delta , Vietnam

    Magister-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Bubaraye Ohiosimuan Dirikumo; [2023]
    Nyckelord :Pesticides; Ecological Risk Assessment ERA ; rice farming; Mekong Delta; PRIMET Model; Exposure Toxicity Ratio ETR ; species sensitivity distribution SSD ; predicted environmental concentrations PECs ;

    Sammanfattning : Pesticide use in rice farming is a common practice in the Mekong Delta and poses ecological risks to aquatic organisms, the environment, and human health. This study focused on the ecological risk assessment of pesticide use in rice farming using the PRIMET model as a decision support tool to evaluate the risks of pesticide exposure, ecotoxicity, and risk characterization, as well as employing the species sensitivity distribution (SSD) assessment model to calculate the potentially affected fraction (PAF) of species based on the computed predicted environmental concentrations (PECs) from PRIMET.

  5. 24. Robust Portfolio Optimization with Correlation Penalties

    Master-uppsats, KTH/Matematisk statistik

    Författare :Pelle Nydahl; [2023]
    Nyckelord :Portfolio Optimization; Portfolio Allocation; Robust Optimization; Correlation; Risk Factor Model; EMA Filtering; Weighted Linear Regression; Portföljoptimering; Portföljallokering; Robust optimering; Korrelation; Riskfaktor-modell; EMA-filtrering; Viktad linjär regression;

    Sammanfattning : Robust portfolio optimization models attempt to address the standard optimization method's high sensitivity to noise in the parameter estimates, by taking an investor's uncertainty about the estimates into account when finding an optimal portfolio. In this thesis, we study robust variations of an extension of the mean-variance problem, where an additional term penalizing the portfolio's correlation with an exogenous return sequence is included in the objective.

  7. 25. TECHNO-ECONOMIC ANALYSIS OFRENEWABLE GAS PRODUCTION AND ELECTRICITY GENERATION FROM ORGANIC WASTE : A Feasibility Study of a Conceptual Biogas Plant in the Santander Region, Colombia

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Nelly Sassersson Busadee; Laura Ahmed; [2023]
    Nyckelord :Organic waste; Biogas; Biomethane; Hydrogen; Waste valorisation; Anaerobic digestion; Combined heat and power; Water scrubbing; Biogas upgrading; Steam methane reforming; Techno-economic analysis; Sensitivity analysis; Colombia;

    Sammanfattning : Strategies to harness the energy from organic waste is gaining importance on a global scale, especially in countries with large quantities of it. In this paper, a techno-economic analysisand a field study were performed to investigate the feasibility of five scenarios for a conceptual biogas facility, based on a case study from Colombia.
