  1. 16. On Parameter Estimation and Control of Time-Varying Stochastic Systems

    Author : Bengt Lindoff; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistics; Adaptive Predictive Control; Adaptive Stochastic Control; Dual Control; Convergence Analysis; Quadratic Forms; Forgetting Factor; Recursive Least Squares; Recursive Estimation; Linear Systems; Time-Varying Stochastic Systems; operations research; programming; actuarial mathematics; Statistik; operationsanalys; programmering; aktuariematematik;

    Abstract : This thesis is about parameter estimation and control of time-varying stochastic systems. It can be divided into two parts. The first part deals with an estimation algorithm commonly used when estimating parameters in time-varying stochastic systems, the Recursive Least Squares (RLS) algorithm with forgetting factor.

  2. 17. Adaptive Task Scheduling and Resource Management Techniques for Improving Energy Efficiency on Multi-core Systems

    Author : Jing Chen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic Voltage and Frequency Scaling DVFS ; Performance Modeling; Energy Efficiency; Runtime System; Power Modeling; Task Scheduling;

    Abstract : The growing impact of energy on operational cost and system robustness becomes a strong motivation for improving energy efficiency in parallel computing systems, in addition to performance. Hardware features such as core asymmetry and Dynamic Voltage and Frequency Scaling (DVFS) aim to provide opportunities for energy-efficient computing. READ MORE

  3. 18. Novelty in the Anthropocene : Exploring past and future novelty in marine social-ecological systems

    Author : Yosr Ammar; Thorsten Blenckner; Malin Pinsky; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Novelty; marine ecosystems; Social-Ecological Systems; Baltic Sea; Complex Adaptive Systems; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : Humans have become the major driving force of change, deeply affecting the Earth system and the biosphere. In marine ecosystems specifically, climate-related environmental changes and anthropogenic pressures (e.g. READ MORE

  4. 19. Exploring connections in social-ecological systems : The links between biodiversity, ecosystem services, and human well-being in South Africa

    Author : Maike Hamann; Reinette (Oonsie) Biggs; Belinda Reyers; Thomas Elmqvist; Fabrice DeClerck; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; complex adaptive systems; mapping; ecosystem service bundles; multidimensional human well-being; biodiversity loss; inequality; research frameworks; interdisciplinarity; natural resource management; sustainable development; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : A key challenge of the Anthropocene is to advance human development without undermining critical ecosystem services. Central to this challenge is a better understanding of the interactions and feedbacks between biodiversity, ecosystem services and human well-being, which interact in dynamic and complex social-ecological systems.
