With negligible fluid inertia, the set of PDEs known as the Stokes equations can be used to model the hydrodynamics. READ MORE

  5. 3. The All-Affected Principle and its Critics : A Study on Democratic Inclusion

    Author : Jonas Hultin Rosenberg; Lundström Mats; Robert Huseby; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; the all-affected principle; democratic inclusion; demos; the boundary problem; normative democratic theory; the all-subjected principle; political equality; internal critique; competence;

    Abstract : The problem of democratic inclusion, which concerns inclusion in and exclusion from the demos, has attracted significant scholarly attention in the last decade. The all-affected principle seeks to resolve this problem by maintaining that all those and only those who are affected should be included in the demos. READ MORE

  6. 4. Exploring the internalization of University-lndustry Collaboration and firm innovation: an analysis of influential roles, problem, and implementation paths

    Author : Daniel hemberg; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Knowledge; University-industry collaboration; Absorptive capacity; Higher education; Academic engagement with industry; Collaborative research; Capabilities; Problem; Boundary spanner; Paths of implementation;

    Abstract : The phenomenon studied here is how cooperatively developed knowledge, resulting from knowledge-related interaction in a university–industry collaboration (UIC), is internally utilized by a firm. The purpose of this research is to explore how knowledge developed in a UIC is utilized by the collaborating firm in the development of innovations. READ MORE

  7. 5. The Double Obstacle Problem on Metric Spaces

    Author : Zohra Farnana; Jan Björn; Anders Björn; Juha Kinnunen; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metric space; nonlinear; obstacle problem; p-harmonic; potential theory; regularity; stability; MATHEMATICS; MATEMATIK;

    Abstract : During the last decade, potential theory and p-harmonic functions have been developed in the setting of doubling metric measure spaces supporting a p-Poincar´e inequality. This theory unifies, and has applications in several areas of analysis, such as weighted Sobolev spaces, calculus on Riemannian manifolds and Carnot groups, subelliptic differential operators and potential theory on graphs.
