  1. 1. Resource Allocation with Potts Mean Field Neural Network Techniques

    Author : Martin Lagerholm; Beräkningsbiologi och biologisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Potts; combinatorial optimization; ANN; mean field; approximation; routing; unicast; multicast; airline crew; scheduling; ECG; NP-complete.; Matematik; Mathematics; algorithm; Systems engineering; computer technology; Data- och systemvetenskap; Fysicumarkivet A:1998:Lagerholm;

    Abstract : Potts mean field artificial neural network techniques are developed and applied to airline crew scheduling problems and routing problems. A propagator formalism in terms of Potts neurons is developed to handle global topological issues. An integrated method for identifying and classifying ECG complexes is presented. READ MORE

  2. 2. Mean Field Games for Jump Non-Linear Markov Process

    Author : Rani Basna; Astrid Hilbert; Rainer Buckdahn; Linnéuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mean-field games; Optimal Control; Non-linear Markov Processes; Mathematics; Matematik;

    Abstract : The mean-field game theory is the study of strategic decision making in very large populations of weakly interacting individuals. Mean-field games have been an active area of research in the last decade due to its increased significance in many scientific fields. READ MORE

    Author : Alexander Aurell; Boualem Djehiche; Xiaoming Hu; Roland Malhamé; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; pedestrian crowds; stochastic differential equations; mean field; stochastic control; games; backward dynamics; sticky boundary; stochastic maximum principle; social conventions; folkmassor; stokastiska differentialekvationer; medelfält; stokastisk styrning; limaktiga randvillkor; stokastiska maximumprincipen; dynamik med ändvillkor; spel; konventioner;

    Abstract : This thesis consists of five appended papers, primarily addressingtopics in pedestrian crowd modeling and the formation of conventions.The first paper generalizes a pedestrian crowd model for competingsubcrowds to include nonlocal interactions and an arbitrary (butfinite) number of subcrowds.

  4. 4. Polyelectrolyte - Surfactant Interactions in Dilute Suspensions. A Study Based on Monte Carlo simulations and Mean-Field Calcultations

    Author : Torsten Wallin; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aggregation number; linear charge density; chain flexibility; mean-field; calculation; simulation; Monte Carlo; cmc; cac; interaction; electrostatic; charged; micelle; polyelectrolyte; surfactant; hydrophilic; hydrophobic; Physical chemistry; Fysikalisk kemi;

    Abstract : The complexation of macroions or charged micelles and oppositely charged polyelectrolytes was studied by the use of Monte-Carlo simulations and mean field calculations. The Monte-Carlo simulations were performed on a simple model system with the emphasis on the electrostatic interaction, (i) polyelectrolyte rigidity, (ii) polyelectrolyte linear charge density, (iii) surfactant tail length, and (iv) the polyelectrolyte concentration.

  5. 5. Multi-Camera Light Field Capture : Synchronization, Calibration, Depth Uncertainty, and System Design

    Author : Elijs Dima; Mårten Sjöström; Roger Olsson; Ulf Assarsson; Mittuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Light field; Camera systems; Multiview; Synchronization; Camera calibration;

    Abstract : The digital camera is the technological counterpart to the human eye, enabling the observation and recording of events in the natural world. Since modern life increasingly depends on digital systems, cameras and especially multiple-camera systems are being widely used in applications that affect our society, ranging from multimedia production and surveillance to self-driving robot localization.
