  1. 6. Generalized Vandermonde matrices and determinants in electromagnetic compatibility

    Author : Karl Lundengård; Sergei Silvestrov; Dietrich von Rosen; Mälardalens högskola; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Abstract : Matrices whose rows (or columns) consists of monomials of sequential powers are called Vandermonde matrices and can be used to describe several useful concepts and have properties that can be helpful for solving many kinds of problems. In this thesis we will discuss this matrix and some of its properties as well as a generalization of it and how it can be applied to curve fitting discharge current for the purpose of ensuring electromagnetic compatibility.

    Abstract : Life is able to replicate itself, e.g., a microorganism is able to divide into two identical ones, and a single plant is able to forest a whole island. READ MORE

  3. 8. Using an Artificial Ecosystem to Understand Living Ecosystems

    Author : Yu Liu; David Sumpter; Philip Gerlee; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mathematical Biology; Mathematical Modeling; Emergence; Ecosystem Evolution; Community Ecology; Mathematics with specialization in Applied Mathematics; Matematik med inriktning mot tillämpad matematik;

    Abstract : Community ecosystems at very different levels of biological organization often have similar properties. Coexistence of multiple species, cross-feeding, biodiversity and fluctuating population dynamics are just a few of the properties that arise in a range of ecological settings. READ MORE

  4. 9. Reinforcement in Biology : Stochastic models of group formation and network construction

    Author : Qi Ma; David Sumpter; Edward Codling; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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

  5. 10. Modeling Specialization and Division of Labor in Cultural Evolution

    Author : Micael Ehn; Eriksson Kimmo; Thomas Mark; Mälardalens högskola; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Specialization; Division of Labor; Cultural Evolution; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Abstract : Division of labor and division of knowledge are so important and common in society today that it is difficult to imagine a functional society where everyone knows the same things and performs the same tasks. In such a society everyone grows, or gathers, and prepares their own food, makes their own tools, builds their own house, and so on. READ MORE
