Simulation Assisted Development of SOFC Power Generation

SOFC Power Generation systems are getting more and more popular in the stationary and marine sector, to move away from traditional internal combustion engines, not only to reduce emissions, but also for higher system efficiency. In this presentation AVL shows how system simulation was initially used for definition of appropriate system architecture, following by correct component selection to fulfill contract efficiency and performance targets. To get the most reliable results at any point of V process development, simulation tool has to be predictive enough in concept phase and it should also offer simple parameterization of components where more data is available, either from component supplier or actual measurements. The complete workflow will be shown to have an idea how AVL is utilizing the software at any point of the V process for SOFC system development.

The relevant issues of the agroecological zoning of Ukraine

The main trends of the territorial analysis of agricultural lands and their environmental assessment are considered. The methodology of information agroecological zoning includes classification of landscape structure and natural-anthropogenic processes on the research area, formation of an information database, parameterization of components and agroecological processes, creation of graphical models of the functioning of agricultural landscapes and adjacent territories. Differentiated approaches have been developed to conduct general scientific and targeted agroecologic zoning of agricultural lands based on landscape-ecological principles. The complex of quantitative parameters of the components of agricultural landscapes for the assessment and zoning of their ecology features is proposed. A tabular legend for the regional general scientific agroecological map of the Right-Bank Forest-Steppe provincial of Ukraine has been prepared. The considered issues of the methodology of agroecological zoning allow to introduce the practice of such research as the basis for the formation of the State program of general scientific and target agroecological zoning of Ukraine.

Maximal $${\mathsf {Sp}}(4,{\mathbb {R}})$$ surface group representations, minimal immersions and cyclic surfaces

Let S be a closed surface of genus at least 2. For each maximal representation $$\rho : \pi _1(S){\rightarrow }{\mathsf {Sp}}(4,{\mathbb {R}})$$ in one of the $$2g-3$$ exceptional connected components, we prove there is a unique conformal structure on the surface in which the corresponding equivariant harmonic map to the symmetric space $${\mathsf {Sp}}(4,{\mathbb {R}})/{\mathsf {U}}(2)$$ is a minimal immersion. Using a Higgs bundle parameterization of these components, we give a mapping class group invariant parameterization of such components as fiber bundles over Teichmuller space. Unlike Labourie’s recent results on Hitchin components, these bundles are not vector bundles.
