  1. 21. Learning-by-modeling : Novel Computational Approaches for Exploring the Dynamics of Learning and Self-governance in Social-ecological Systems

    Författare :Emilie Lindkvist; Maja Schlüter; Jon Norberg; Örjan Ekeberg; James Dyke; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Complex adaptive systems; Renewable resources; Adaptive management; Small-scale fisheries; Artificial intelligence; Reinforcement learning; Agent-based modeling; agent-baserade modeller; artificiell intelligens; social-ekologiska system; komplexa adaptiva system; förnyelsebara naturresurser; adaptiv förvaltning; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : As a consequence of global environmental change, sustainable management and governance of natural resources face critical challenges, such as dealing with non-linear dynamics, increased resource variability, and uncertainty. This thesis seeks to address some of these challenges by using simulation models. LÄS MER

  3. 22. Eco-evolutionary processes and community patterns--- novel avenues for studying biodiversity across spatial and temporal scales

    Författare :Yun-Ting Jang; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Eco-evolutionary dynamics; Community diversity patterns; Spatial phylogenetic patterns; Adaptive dynamics; Elevational diversity gradients; Theoretical ecology; Simulation models; Predation; Competition;

    Sammanfattning : Understanding biodiversity patterns poses a persistent challenge due to the complex interconnections of ecological and evolutionary processes. The particular difficulty comes from the various processes influencing biodiversity patterns across different spatial scales. LÄS MER

  4. 23. Efficient Exploration and Robustness in Controlled Dynamical Systems

    Författare :Alessio Russo; Alexandre Proutiere; Henrik Sandberg; Marcello Restelli; Nikolai Matni; Jana Tumova; Mikael Asplund; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforcement learning; efficient exploration; bandit algorithms; adversarial attacks; conformal prediction; data posioning; markov decision processes; attack detectability; optimal control; adaptive control; Electrical Engineering; Elektro- och systemteknik; Datalogi; Computer Science; Mathematical Statistics; Matematisk statistik;

    Sammanfattning : In this thesis, we explore two distinct topics. The first part of the thesis delves into efficient exploration in  multi-task bandit models and model-free exploration in large Markov decision processes (MDPs). LÄS MER

  5. 24. Designing Self-Adaptive Software Systems with Reuse

    Författare :Nadeem Abbas; Jesper Andersson; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Variability; Uncertainty; Self-Adaptation; Software Reuse; Software Design; Methodology; Domain Engineering.; Computer Science; Datavetenskap; Data- och informationsvetenskap; Computer and Information Sciences Computer Science; Software Technology; Programvaruteknik;

    Sammanfattning : Modern software systems are increasingly more connected, pervasive, and dynamic, as such, they are subject to more runtime variations than legacy systems. Runtime variations affect system properties, such as performance and availability. The variations are difficult to anticipate and thus mitigate in the system design. LÄS MER

  7. 25. Adaptive Evolution of the Bacterial Translation Machinery

    Författare :Arindam De Tarafder; Suparna Sanyal; Michael Y. Pavlov; Ruben L. Jr. Gonzalez; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ribosome; Translation; Translation machinery; Elongation; Evolution; RNA world; Cold bacteria; Molekylär biovetenskap; Molecular Life Sciences;

    Sammanfattning : The process of protein synthesis via translation is of paramount importance for the existence of life on Earth. The bacterial translation machinery has embraced more than 3.5 billion years of molecular evolution to adapt and function efficiently under the provided physiological conditions. LÄS MER
