  1. 6. Accelerating Convergence of Large-scale Optimization Algorithms

    Författare :Euhanna Ghadimi; Mikael Johansson; Angelia Nedich; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Convex optimization; Large-scale systems; First-order methods; Convergence analysis; ADMM; Optimization algorithms; Electrical Engineering; Elektro- och systemteknik; Matematik; Mathematics;

    Sammanfattning : Several recent engineering applications in multi-agent systems, communication networks, and machine learning deal with decision problems that can be formulated as optimization problems. For many of these problems, new constraints limit the usefulness of traditional optimization algorithms. LÄS MER

  3. 7. Functions of Generalized Bounded Variation

    Författare :Martin Lind; Viktor Kolyada; Peter Oswald; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bounded p-variation; generalized bounded variation; modulus of continuity; function spaces; embeddings; Matematik; Mathematics;

    Sammanfattning : This thesis is devoted to the study of different generalizations of the classical conception of a function of bounded variation.First, we study the functions of bounded p-variation introduced by Wiener in 1924. We obtain estimates of the total p-variation (1.. LÄS MER

  4. 8. Personality, Health and Mortality of Workers in a PVC Production Plant in Sweden A longitudinal study

    Författare :Margareta Ardeberg; Miljö- och energisystem; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mortality; disease; recovery; personality alterations; solvents exposure; PVC; polyvinyl chloride; Sjöbring personality psychology; behavioural toxicology; MNT scale; MFS scale; Eysenck; Psychology; Psykologi;

    Sammanfattning : A longitudinal study was initiated in a PVC production plant in 1967. It was repeated in 1987. A cohort of 101 workers was followed. The aim of the 1967 study was, after a heavy rise in absenteeism and sick leave, to analyze perceptions of work environment and health. LÄS MER

  5. 9. Functional and structural characterizations of phytoplankton-bacteria interactions in response to environmental challenges

    Författare :Eva Sörenson; Catherine Legrand; Elin Lindehoff; Jarone Pinhassi; Sonya Dyhrman; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Interactions; phytoplankton; microalgae; bacteria; communities; aquatic; diversity; functions; structure; species-specific; microbiome; core microbiome; response diversity; resilience; resource partitioning; competition; coexistence; amplicon sequencing; metatranscriptome; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology;

    Sammanfattning : Microorganisms, such as phytoplankton and bacteria, make up ≈70% of aquatic biomass and contribute 50-85% of the oxygen in Earth’s atmosphere. The microbial loop concept and the discovery of the large diversity in microbial communities acknowledge that biotic interactions between microorganisms in addition to resource competition enable the recycling of energy and nutrients in aquatic food webs.
