Adaptive Cube Tessellation for Topologically Correct Isosurfaces

Three dimensional datasets representing scalar fields are frequently rendered using isosurfaces. For datasets arranged as a cubic lattice, the marching cubes algorithm is the most used isosurface extraction method. However, the marching cubes algorithm produces some ambiguities which have been solved using different approaches that normally imply a more complex process. One of them is to tessellate the cubes into tetrahedra, and by using a similar method (marching tetrahedra), to build the isosurface. The main drawback of other tessellations is that they do not produce the same isosurface topologies as those generated by improved marching cubes algorithms. We propose an adaptive tessellation that, being independent of the isovalue, preserves the topology. Moreover the tessellationallows the isosurface to evolve continuously when the isovalue is changed continuously.

Knowledge Creation as a Square Dance on the Hilbert Cube

This paper presents a micro-model of knowledge creation and transfer in a small group of people. Our model incorporates two key aspects of the cooperative process of knowledge creation: (i) heterogeneity of people in their state of knowledge is essential for successful cooperation in the joint creation of new ideas, while (ii) the very process of cooperative knowledge creation a¤ects the heterogeneity of people through the accumulation of knowledge in common. The model features myopic agents in a pure externality model of interaction. In the two person case, we show that the equilibrium process tends to result in the accumulation of too much knowledge in common compared to the most productive state. Unlike the two-person case, in the four person case we show that the equilibrium process of knowledge creation may converge to the most productive state. Equilibrium paths are found analytically, and they are a discontinuous function of initial heterogeneity.

Bosnia and Herzegovina: Building a Film/TV Production Industry to Boost its Economy and Unite its Divided Cultures

This paper discusses how Bosnia and Herzegovina (BiH) can boost its stalled economy by generating jobs and increasing film-tourism, while simultaneously helping unite its culturally divided nation, by building a film/TV production industry looking to Northern Ireland's successful model following its similarly violent history. Evidence is presented substantiating that BiH has the infrastructure and workforce from which to grow a film/TV production industry, but it must be built through large-scale foreign productions like Northern Ireland did with Game of Thrones. Examining studies conducted by industry experts, strategies are offered for building a competitive and sustainable film/TV production industry in BiH. Results reveal more research is needed evidencing film/TV production can unify people from different ethno-religious/political groups in post-conflict societies.
