  2. 1. Accuracy, efficiency and robustness for rigid particle simulations in Stokes flow

    Author : Anna Broms; Anna-Karin Tornberg; Mattias Sandberg; Eric Keaveny; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stokes flow; rigid particles; accuracy; fundamental solutions; method of images; multiblob; contact avoiding; complementarity problem; barrier method; elliptic PDE; grid optimisation; pair-correction; boundary integral equations; Stokesflöde; noggrannhet; stela partiklar; fundamentallösningar; randintegralekvation; reflektionspunkter; multiblob; kontaktundvikande algoritmer; komplementaritetsproblem; barriärmetod; elliptisk PDE; gridoptimering; parkorrektion; Numerical Analysis; Numerisk analys;

    Abstract : The thesis concerns simulation techniques for systems of nano- to micro-scaled rigid particles immersed in a viscous fluid, ubiquitous in nature and industry. With negligible fluid inertia, the set of PDEs known as the Stokes equations can be used to model the hydrodynamics. READ MORE

  5. 3. On the Einstein-Vlasov system: Stationary Solutions and Small Data Solutions with Charged and Massless Particles

    Author : Maximilian Thaller; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Static Solutions; Vector Field Method; non-linear wave equation; massless Einstein-Vlasov system; General Relativity; Conformal Einstein Field Equations; Minkowski stability; Vlasov matter; symmetric hyperbolic system; Einstein-Vlasov-Maxwell system;

    Abstract : The Vlasov matter model describes an ensemble of collisionless particles moving through space-time. These particles interact via the gravitational field which they create collectively. In the framework of General Relativity this gravitational field is described by space-time curvature. READ MORE

  6. 4. Global project management : developing system solutions in a multi-organizational environment

    Author : Joakim Lilliesköld; KTH; []
    Keywords : Project management; Globally distributed teams; Industrial projects; Global development projects; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The traditional view of project management is beingchallenged by the globalization of markets, mergers ofinternational companies, and the integration of managerial andbusi-ness processes in global corporations. The development ofInformation Technology and the rapid growth of the Internet hascreated an opportunity to utilize global resources, resultingin new and unique problems within project management researchthat need to be addressed.

  7. 5. Dependable Distributed Control System : Redundancy and Concurrency defects

    Author : Bjarne Johansson; Thomas Nolte; Alessandro Papadopoulos; Luis Almeida; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Abstract : Intelligent devices, interconnectivity, and information exchange are characteristics often associated with Industry 4.0. A peer-to-peer-oriented architecture with the network as the system center succeeds the traditional controller-centric topology used in today's distributed control systems, improving information exchange in future designs.
