  1. 1. Shifting focus from yields to food supply : an evaluation of the ‘number of people fed per hectare’ indicator at farm and national level

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Ida Ekqvist; [2024]
    Nyckelord :Land use efficiency; Sustainability indicators; Agricultural productivity; Food production;

    Sammanfattning : The challenge of feeding a growing global population while reducing the pressure on climate and ecosystems has gained much attention in research over the last decades. A crucial yet often overlooked aspect in research addressing this complex challenge is the efficiency of food production in meeting nutritional needs within the constraints of global cropland resources.

  3. 2. Evaluating aperture shape controller (ASC) in modulated radiation treatments

    Master-uppsats,

    Författare :Vilma Andrén Cederholm; [2023-09-28]
    Nyckelord :Medical physics;

    Sammanfattning : To decrease aperture complexity, the aperture shape controller (ASC) is a recently introduced function in Eclipse external beam planning (Varian Medical Systems, Palo Alto, USA). ASC works within the photon optimizer, minimizing distances between adjacent leaf tips of the MLC. LÄS MER

  4. 3. Taking Climate into Account - Carbon Management Tools for Investment Decisions and Progress Tracking at an Energy Company

    Master-uppsats, Lunds universitet/Innovationsteknik

    Författare :Rebecca Ahlin; Anna Malmberg; [2023]
    Nyckelord :Carbon accounting; carbon disclosure; carbon management; carbon management tools; environmental change management; internal carbon price; Technology and Engineering;

    Sammanfattning : Background: Climate change is becoming a more urgent issue, where global agreements and regulations are putting pressure on companies to calculate and disclose their greenhouse gas emissions to combat the problem. Other driving forces of carbon disclosure for companies include social, economic, and financial pressure, as well as firm specific internal factors. LÄS MER

  5. 4. Towards Building Privacy-Preserving Language Models: Challenges and Insights in Adapting PrivGAN for Generation of Synthetic Clinical Text

    Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Atena Nazem; [2023]
    Nyckelord :Generative Adversarial Networks; privacy-preserving language models; clinical text data; reinforcement learning; synthetic data;

    Sammanfattning : The growing development of artificial intelligence (AI), particularly neural networks, is transforming applications of AI in healthcare, yet it raises significant privacy concerns due to potential data leakage. As neural networks memorise training data, they may inadvertently expose sensitive clinical data to privacy breaches, which can engender serious repercussions like identity theft, fraud, and harmful medical errors.

  7. 5. A geometric approach to calculating the limit set of eigenvalues for banded Toeplitz matrices

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Teodor Bucht; [2023]
    Nyckelord :Toeplitz matrices; Banded Toeplitz matrices; Limit set; Eigenvalues; Mathematics and Statistics;

    Sammanfattning : This thesis is about the limiting eigenvalue distribution of n × n Toeplitz matrices as n → ∞. The two classical questions we want to answer are: what is the limit set of the eigenvalues, and what is the limiting distribution of the eigenvalues. Our main result is a new approach to calculate the limit set Λ(b) for a Laurent polynomial b, i.e. LÄS MER
