  1. 1. The layer that did not swim away : Broadband acoustic discrimination and characterization of ocean stratification

    Författare :Elizabeth Reed-Weidner; Martin Jakobsson; Richard Hobbs; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acoustical Oceanography; acoustics; oceanography; stratification; remote sensing; maringeologi; Marine Geology;

    Sammanfattning : Ocean stratification plays a critical role in many oceanographic processes. The magnitude of mixing between stable water masses is regulated, in part, by the intensity of stratification. LÄS MER

  3. 2. Tools for Control System Design : Stratification of Matrix Pairs and Periodic Riccati Differential Equation Solvers

    Författare :Stefan Johansson; Bo Kågström; Erik Elmroth; Paul Van Dooren; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; control system design; stratification; controllability; observability; matrix pair; canonical forms; linear quadratic regulator; periodic systems; periodic Riccati differential equation; Computer science; Datavetenskap; Numerical Analysis; numerisk analys;

    Sammanfattning : Modern control theory is today an interdisciplinary area of research. Just as much as this can be problematic, it also provides a rich research environment where practice and theory meet. This Thesis is conducted in the borderline between computing science (numerical analysis) and applied control theory. LÄS MER

  4. 3. Numerical Investigation of Rotating and Stratified Turbulence

    Författare :Enrico Deusebio; Erik Lindborg; Johan Nilsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geostrophic turbulence; stable stratification; rotation; wall-bounded turbulence; gravity waves; atmospherical dynamics; direct numertical simulations; SRA - E-Science SeRC ; SRA - E-vetenskap SeRC ;

    Sammanfattning : Atmospheric and oceanic flows are strongly affected by rotation and stratification. Rotation is exerted through Coriolis forces which mainly act in horizontal planes whereas stratification largely affects the motion along the vertical direction through buoyancy forces, the latters related to the vertical variation of the fluid density.

  5. 4. On the Arctic Boundary Layer : From Turbulence to Climate

    Författare :Thorsten Mauritsen; Gunilla Svensson; Joao Teixeira; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atmospheric boundary layers; Turbulence; Stable stratification; Gravity waves; Mesoscale motion; Arctic climate; Meteorology; Meteorologi; atmosfärvetenskap; Atmospheric Sciences;

    Sammanfattning : The boundary layer is the part of the atmosphere that is in direct contact with the ground via turbulent motion. At mid-latitudes the boundary layer is usually one or a few kilometers deep, while in the Arctic it is much more shallow, typically a few hundred meters or less. LÄS MER

  7. 5. "Rörlig och stabil, bred och spetsig”. Kulturell reproduktion och strategier för breddat deltagande i den svenska kulturskolan : “Dynamic and stable, broad and deep”. Cultural reproduction and strategies for widening participation in the Swedish kulturskolor

    Författare :Cecilia Jeppsson; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; kulturskola; Community Schools of Music and Arts; music education; widening participation; social inclusion; cultural reproduction; social stratification; field theory; Bourdieu; positioning; institutional discourses; cross-field effects;

    Sammanfattning : One point of departure of this study is the intensified national interest at the policy level in Swedish kulturskolor (Community Schools of Music and Arts) as an inclusive and accessible institution. Yet, the field can be described as torn between tradition and change. LÄS MER
