  1. 16. Attraction Based Models of Collective Motion

    Author : Daniel Strömbom; David J. T. Sumpter; Andreas Deutsch; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; flocking; swarming; self-propelled particles; alignment-free models; agent-based modelling; leaf-cutting ant traffic; sheep-sheepdog system; the Shepherding problem; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

    Abstract : Animal groups often exhibit highly coordinated collective motion in a variety of situations. For example, bird flocks, schools of fish, a flock of sheep being herded by a dog and highly efficient traffic on an ant trail. READ MORE

  2. 17. Reinforcement in Biology : Stochastic models of group formation and network construction

    Author : Qi Ma; David Sumpter; Edward Codling; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; reinforcement in biology; merge and split model; preferential attachment; reinforced random walk; network construction; shortest path problem; transport networks; ant algorithm; slime mould; physarum polycephalum; speed-accuracy tradeoff.; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

    Abstract : Empirical studies show that similar patterns emerge from a large number of different biological systems. For example, the group size distributions of several fish species and house sparrows all follow power law distributions with an exponential truncation. READ MORE

  3. 18. SOCIOTECHNICAL IMAGINARIES OF THE AUTOMATED MUNICIPALITY

    Author : Daniel Toll; Ida Lindgren; Ulf Melin; Lupita Svensson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : In the last few years, Swedish municipalities have striven to adopt automation to increase their internal efficiency by automating administrative processes. This E-Government initiative is taking place as part of the ongoing digitalization efforts by Swedish municipalities. READ MORE

  4. 19. Mathematical modelling approach to collective decision-making

    Author : Natalia Zabzina; Denis Gaidashev; Torbjörn Lundh; Uppsala universitet; []
    Keywords : collective behaviour; collective decision-making; communication mechanisms; positive feedback; mathematical modelling; bifurcation phenomena; steady state solutions; symmetry breaking; symmetry restoring; diffusion-limited aggregation; fractal dimension;

    Abstract : In everyday situations individuals make decisions. For example, a tourist usually chooses a crowded or recommended restaurant to have dinner. Perhaps it is an individual decision, but the observed pattern of decision-making is a collective phenomenon. READ MORE

  5. 20. Modeling Collective Decision-Making in Animal Groups

    Author : Boris Granovskiy; David J. T. Sumpter; Mary R. Myerscough; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; collective animal behavior; collective intelligence; swarm intelligence; wisdom of crowds; mathematical modeling; stochastic modeling; agent-based modeling; Markov chain models;

    Abstract : Many animal groups benefit from making decisions collectively. For example, colonies of many ant species are able to select the best possible nest to move into without every ant needing to visit each available nest site. READ MORE
