  2. 1. Polymer-Mediated Interactions and Phase Behaviour of Polymer-Particle Dispersions

    Author : Sara Haddadi; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Simulations; Experiments; Particles; Phase transition; Stability; capillary induced phase separation; Polymer solutions; phase diagram; surface effects; Bulk properties;

    Abstract : Interactions between colloidal particles can be modelled by particles grafted with polymers. In this work, structural and physical properties of colloids are investigated under variation of parameters such as pH, ionic strength, and temperature, where aggregation and cluster formation can be monitored in aqueous solution.

  4. 2. Visualizing the Effects of Geometrical Variation on Perceived Quality in Early Phases

    Author : Ola S Wagersten; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometrical variation; geometry assurance; non-rigid; product development; tolerance analysis; variation simulation; visualization and evaluation.; perceived quality;

    Abstract : In a perfect world, geometrical variation in a manufacturing process would not exist. Every component produced in a series would have the exact same dimensions and, when observed by a trained eye, look exactly identical. However, the world is not perfect and neither are manufacturing processes. READ MORE

  5. 3. Phase-field modeling of surface-energy driven processes

    Author : Klara Asp Grönhagen; John Ågren; Suzana Fries; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-field method; surface energy; solute drag; solid-state sintering; multicomponent multiphase flow; wetting; liquid-phase sintering; spinodal decomposition; CALPHAD; Materials science; Teknisk materialvetenskap;

    Abstract : Surface energy plays a major role in many phenomena that are important in technological and industrial processes, for example in wetting, grain growth and sintering. In this thesis, such surface-energy driven processes are studied by means of the phase-field method. READ MORE

  6. 4. Spectrally Efficient Continuous Phase Modulation

    Author : Tommy Svensson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spectrum efficiency; Laurent decomposition; additive white Gaussian noise AWGN ; trellis coded modulation TCM ; non-linear channels; continuous phase modulation CPM ; maximum likelihood sequence detection MLSD ; distance spectrum; convolutional codes;

    Abstract : Spectrally efficient continuous phase modulation (CPM) systems and generalizations of CPM for wireless links are considered. Continuous phase modulation defines constant envelope phase codes, which are advantageous when using non-linear amplifiers. READ MORE

  7. 5. Eliciting Knowledge from Experts in Modeling of Complex Systems : Managing Variation and Interactions

    Author : Per Wikberg; Bo Strangert; Erland Svensson; Berndt Brehmer; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Modeling; Experts; Communication; Qualitative Data; Roles; Cognitive science; Kognitionsvetenskap;

    Abstract : The thematic core of the thesis is about how to manage modeling procedures in real settings. The view taken in this thesis is that modeling is a heuristic tool to outline a problem, often conducted in a context of a larger development process. READ MORE
