Activity at IFE Wind Energy: numerical modeling of offshore wind turbines

IFE (Institutt for Energiteknikk) is a research center located in Kjeller. The wind group at IFE mainly works with the development and analysis of new cost effective concepts for offshore wind energy, both concerning innovative rotor designs and new concepts for substructures. The group main investigation tool is the in-house software 3DFloat, an aero-elastic code which can simulate the whole wind turbine structure when exposed to the associated environmental loads (wind loads, hydrodynamic loads, soil loads if bottom-fixed).

In the presentation, an insight into the wave kinematics and wave loads modeling tools that are currently included in 3DFloat will be provided.

This Friday, April 28th, we're discussing a recent paper on the newest SSE model by Rabosky & Goldberg (2017): "FiSSE: A simple nonparametric test for the effects of a binary character on lineage diversification rates".

Hope to see you there!

Most demographic population models ignore males, but empirical evidence suggest that they should be included when vital rates are sex-specific. Assumptions about adult sex ratio, social structure, and mating system have been shown to affect estimates of extinction risk and projections of population dynamics. We discuss about when and how to apply two-sex models.

The second Scandinavian Gathering Around Remarkable Discrete Mathematics

 In this talk all spaces and spectra will be localised at 2. Many E-infinity ring spectra turn out to be `finitely generated' in the sense that there is finite CW spectrum and a map from the free E-infinity ring spectrum generated by it inducing an epimorphism in mod 2 homology. This turns out to be an interesting condition and I will discuss some examples such as HZ, kO, kU, tmf and tmf_1(3). One long term goal of this work is to produce `ultra-generalised Brown-Gitler spectra' and I will discuss this idea if there is time.

I will discuss how one-dimensional interacting fermion systems, which in the low energy approximation are described by Luttinger liquid theory, can be reformulated as systems of weakly interacting particles with fractional charge and statistics. The approach is to use Landau's phenomenological approach to Fermi liquid theory, with quasiparticles interpreted as adiabatically dressed fermions. In an earlier publication the local charge carried by these excitations has been shown to be a fraction of the fermion charge. I will here focus on the statistics of the quasiparticles and show that by a change of momentum variables the Landau parameters of the generalized Fermi fluid can be transformed to zero. This change in interaction is compensated by a change of the Pauli exclusion, which is consistent with the interpretation of the quasiparticles as satisfying generalized exclusion statistics.
