The planning of large infrastructure facilities such as inner-city subway tracks requires the consideration of widely differing scales, ranging from the kilometer scale for the general routing of the track down to the centimeter scale for detailed design of connection points. On the one hand this implies the utilization of both, Geographic Information Systems (GIS) as well as Building Informati...

Polycrystalline microstructure often plays an important role in determining the macroscopic behavior of metals. This work is motivated by the case of a spin-formed shaped charge liner. When these liners are compressed and inverted by detonation of an explosive charge, the resulting jet of material exhibits a distinct rotation. There is no asymmetry at the macroscopic level that would suggest a ...

Rosette nanotubes (RNTs) are supramolecular nanomaterials formed through a network of non-covalent interactions, such as hydrogen bonds, π-π interactions, and hydrophobic effects. They form from Watson-Crick inspired guanine-cytosine (G∧C) motifs, which undergo hierarchical self-assembly to form supermacrocycles, also called rosettes. The latter self-organize into ring stacks (RSs) or helical c...

Atomistic (atom-scale) and coarse-grained (meso-scale) simulations of structure and dynamics of poly-isoprene melts are compared. The local structure and chain packing is mainly determined by the atomistic details of the polymer architecture. The large-time dynamics encountered in NMR experiments can be explained by meso-scale simulations including stiffness. The connecting link between the two...

Large-scale image-based modeling is a challenging and important research topic, which has wide applications in various areas. Existed serial methods consume a significant amount of time for large problems. With the emergence of multi-core computers, it is possible to speed up the method using central processing unit (CPU) parallelism. In this paper, we present the design and implementation of m...

MOTIVATION Normal development of multicellular organisms is regulated by a highly complex process in which a set of precursor cells proliferate, differentiate and move, forming over time a functioning tissue. To handle their complexity, developmental systems can be studied over distinct scales. The dynamics of each scale is determined by the collective activity of entities at the scale below it...

Computer models for cement hydration has been proven to be a useful tool for understanding the chemistry of cement hydration, simulating the microstructure development of hydrating paste and predicting the properties of the hydration process /1/. One of these advanced models is CEMHYD3D, which is used and extended within the University of Twente for the last 12 years with pore water chemistry /...

Multi-agent predictive modeling is an essential step for understanding physical, social and team-play systems. Recently, Interaction Networks (INs) were proposed for the task of modeling multi-agent physical systems, INs scale with the number of interactions in the system (typically quadratic or higher order in the number of agents). In this paper we introduce VAIN, a novel attentional architec...
