To study material phenomena simultaneously at various length scales, descriptions in which matter can be coarse grained to arbitrary levels are necessary. Attempts to do this in the static regime (i.e., zero temperature) have already been developed. We present an approach that leads to a dynamics for such coarse grained models. This allows us to obtain temperature-dependent and transport proper...

The paper presents the evaluation of the mechanical and fatigue properties of an ultrafine-grained (UFG) Al 6061 alloy processed by high-pressure torsion (HPT) at room temperature (RT). A comparison is made between the UFG state and the coarse-grained (CG) one subjected to the conventional aging treatment Т6. It is shown that HPT processing leads to the formation of the UFG microstructure with ...

In this work we describe an architecture that supports the composition of web based lesson plans for math based on a database of fine grained mathematical components. Lessons can be tailored for different communities of users. For this research, the principal target community of users is middle school mathematics teachers. Our goal is to build a web accessible resource of pedagogical material f...

Stylolites are rough dissolution pairs of surfaces that are generated by stress induced solution. These irregular structures can be found in various rock types and are mainly filled with fine-grained insoluble material. Stylolites are known to represent self-affine structures that have characteristic statistical properties (Schmittbuhl et al., 2004). We therefore investigate the scaling behavio...

We present an RST-based discourse annotation proposal used in the construction of a trial multilingual XML-tagged corpus of teaching material in Basque, English and Spanish. The corpus feeds an experimental multilingual document generation system for the web. The main contributions of this paper are an implementation of RST through XML metadata and the adoption of gross-grained RST to avoid non...
