Printmaking in the Expanded Field

"Printmaking in the Expanded Field" took place at Oslo National Academy of Arts september 15-18th, 2015. The seminar took 5 years to develop and was initiated by professor Jan Pettersson, head of the Printmaking Department, at the Department for Art and Craft at The Oslo National Academy of the Arts and in collaboration with Trykkeriet in Bergen and Päivikki Kallio, Professor of Printmaking at the Finnish Academy of Fine Arts, Helsinki Finland. The aim with this 4 day seminar was through invitation of a number of prominent artists, theorists, curators and museum representatives on a global basis to discuss the situation of printmaking today out from the tradition, the theoretical aspect, the historical and what is happening and can happen on the global arena in the future. With “Printmaking in the Expanded Field“ we want to create a focused seminar with the Nordic field as the primary impact. Our Nordic Institutions of education has a common cultural platform which creates an excellent base for the further development of the media also in an international context

The Parameterized Complexity of Finding a 2-Sphere in a Simplicial Complex

We consider the problem of finding a subcomplex K\u27 of a simplicial complex K such that K\u27 is homeomorphic to the 2-dimensional sphere, S^2. We study two variants of this problem. The first asks if there exists such a K\u27 with at most k triangles, and we show that this variant is W[1]-hard and, assuming ETH, admits no O(n^(o(sqrt(k)))) time algorithm. We also give an algorithm that is tight with regards to this lower bound. The second problem is the dual of the first, and asks if K\u27 can be found by removing at most k triangles from K. This variant has an immediate O(3^k poly(|K|)) time algorithm, and we show that it admits a polynomial kernelization to O(k^2) triangles, as well as a polynomial compression to a weighted version with bit-size O(k log k)

Well-to-tank data for advanced tailor-made biofuel alternatives

The transport sector accounts for almost 25% of Europe\u27s GHG emissions and is the main cause of air pollution in cities. As part of the effort to increase the sustainability of the transport sector, and to reach the national vision for a vehicle fleet that is independent of fossil fuels by 2030 Sweden set of goals for an increased share of renewables in the transport sector, also following the EU target of at least 10% by 2020. The major goal, for the larger project, is to contribute with applicable data for promoting the best biofuel alternatives for a medium term future with both improved engine combustion concepts and sustainable production pathways. Feedstock potential and integration opportunities with existing industry infrastructure for improved techno-economic and environmental production performance will also be an inherent part of the biofuels analysis of WTT performance. In this literature review focus is on finding different relevant pathways for the production of biomass based drop-in fuels such as n-octanol, 2-ethyl-hexanol, n-decanol, 2-propyl-heptanol, DNBE, 2-MTHF, Caromax, and PolyDME (or POMDME or OME). To illustrate the methodology, one of the Diesel-like biofuels – 2-ethylhexanol – has been chosen and three different production pathways are analyzed for their energy performance. 2-ethylhexanol can be produced via the following three routes: (1)Butanol-based via Guerbet condensation, (2)Ethanol-based via the intermediate product n-butyraldehyde, and (3) Gasification-based via OXO-synthesis. The performance of the three routes will be compared to results for other biofuels serving as Diesel drop-i
