1. 1. Voronoi-Based Coding

   Författare :Erik Agrell; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Voronoi diagram; linear block code; Gaussian channel; neighbor descent; nearest neighbor search algorithm; computational geometry; asymptotic theory; source coding; lattice; vector quantization; soft-decision decoding; index assignment; channel coding; complexity;

   Sammanfattning : The performance of a digital communication system can generally be improved by increasing the number of variables being jointly coded. In this sense, it is desirable to have, e.g., higher-dimensional quantizers, longer channel codes, and more users in a multiple-access system. LÄS MER

3. 2. Transforming and Strengthening the Links Between Industrial Design, Engineering Design and Production

   Författare :Axel Nordin; Innovation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical engineering design; industrial design; customization; optimization; Morphological repertoire; constraint handling; production; genetic algorithm; voronoi diagram; Renaissance 2.0;

   Sammanfattning : The current form-giving activity in industrial design is characterized by explorations that depend on the individual capability to mentally manipulate a solution space from which to select and express the intended result. Designers often rely on artistic experimentation, aesthetic inspiration, or product specifications. LÄS MER

4. 3. Mathematical Modelling and Methods for Load Balancing and Coordination of Multi-Robot Stations

   Författare :Edvin Åblad; Chalmers tekniska högskola; []

7. 5. Space-adaptive simulation of transition and turbulence in shear flows

   Författare :Daniele Massaro; Philipp Schlatter; Saleh Rezaeiravesh; Alfredo Pinelli; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence; global stability; coherent structures; adaptive mesh refinement; Turbulens; global stabilitet; koherenta strukturer; adaptiv nätförfining; Teknisk mekanik; Engineering Mechanics;

   Sammanfattning : Transitional and turbulent shear flows are ubiquitous, from the boundary layer developing on an aeroplane wing to the flow within the aortic arch. In this thesis, we study wall-bounded and free shear flows through direct numerical simulations. LÄS MER
