  1. 1. Convexity, Currents, and Lelong numbers

    Författare :Aron Lagerberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; complex analysis; convex analysis; currents; Lelong numbers; tropical geometry; L^2-estaimtes; Legendre transform; intersection theory; real Monge-Ampere operators; plurisubharmonic functions; integrability index; L^2-estaimtes;

    Sammanfattning : This thesis treats different aspects of convexity, both real and complex. On the real side, we study convexity in relation with certain currents. On the complex side, we study the singularities of plurisubharmonic functions. LÄS MER

  3. 2. Propagation of singularities for pseudo-differential operators and generalized Schrödinger propagators

    Författare :Karoline Johansson; Joachim Toft; Anders Olofsson; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Banach spaces; Fourier; Generalized time-dependent Schrödinger equation; Micro-local; Modulation spaces; Non-tangential convergence; Pseudo-differential operators; Regularity; Wave-front sets; Banachrum; Fourier; Generaliserad tidsberoende Schrödinger ekvation; Icke-tangentiell konvergens; Mikrolokal; Modulationsrum; Pseudodifferentialoperatorer; Regularitet; Vågfrontsmängder; Mathematical analysis; Analys; Mathematics; Matematik;

    Sammanfattning : In this thesis we discuss different types of regularity for distributions which appear in the theory of pseudo-differential operators and partial differential equations. Partial differential equations often appear in science and technology. LÄS MER

  4. 3. Benthic diatoms in the Gulf of Bothnia : Community analysis and diversity

    Författare :Svenja Busse; Michael Sullivan; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Baltic Sea; Biodiversity; Biomass; Community ecology; Diatoms; Multivariate analysis; Navicula; Phytobenthos; Salinity gradient; Scale; Size; Water movement; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Ecological Botany; Ekologisk botanik;

    Sammanfattning : Benthic diatoms are valuable tools for biological monitoring and paleo-ecological reconstruction of past environmental conditions. This thesis aims at describing size-related properties of benthic diatoms and suggests that data assessment for community analysis can be improved by considering the importance of scale. LÄS MER

  5. 4. Capacitive Biosensor - A Tool for Ultrasensitive Analysis : Application in Clinical Analysis and Process Monitoring

    Författare :Kosin Teeparuksapun; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Capacitive Biosensor; Ultrasensitive Analysis; Clinical Analysis; Bioprocess Monitoring; Human Serum Albumin; HIV-1 p24; Host Cell Proteins; Protein A; Current Pulse;

    Sammanfattning : Increasing demands for highly sensitive, accurate, fast and portable analytical assays have led to the development of new analytical tools. The integration of highly specific biological sensing elements and appropriate transducers has enabled design of even more efficient biosensor devices for the detection of target substances. LÄS MER

  7. 5. Svensk brevkultur på 1800-talet : Språklig och kommunikationsetnografisk analys av en familjebrevväxling

    Författare :Kristina Persson; Mats Thelander; Carin Östman; Jan Svensson; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Scandinavian languages - general; correspondence; letter-writing; social practice; literacy; nineteenth century; Swedish; address; variation in style; Nordiska språk - allmänt; Scandinavian languages; Nordiska språk; Scandinavian Languages;

    Sammanfattning : In this dissertation, I examine the correspondence of an upper middle-class family from the early part of the nineteenth century. My aim is to answer questions about correspondence and letter-writing as an everyday event and as a social activity. My principal theoretical framework has been ethnograpy of communication. LÄS MER
