RDF, a simple yet expressive data model, is widely recognised as the foundation for the Semantic Web. We revisit the RDF specification and analyse five problems: literals are not addressable, blank nodes are not addressable, reification is not semantically recognised, language tags are not addressable, and language tags can not be combined. We introduce SiRDF, a simplified data model with fewer...

Intelligent human-machine interfaces based on multimodal interaction are developed separately in different application areas. No unified opinion exists about the issue of what properties should these interfaces have to provide an intuitive and natural interaction. Having carried out an analytical survey of the papers that deal with intelligent interfaces a set of properties are presented, which...

To address the lack of user-friendly software needed to simplify utilization model data across Heliophysics, Community Coordinated Modeling Center (CCMC) at NASA Goddard Space Flight has developed a model-agnostic method via Kamodo for users easily access and utilize in their workflows. By abstracting away broad range file formats intricacies interpolation on specialized grids, this approach si...

One of the factors which limits the transmission capacity of the fiber optics communication channel is the material dispersion. Exact analytical study of the material dispersion is often complex and involves calculating the derivatives of the refractive index of the core. These calculations are too cumbersome to do, especially for high-order derivatives. So material dispersion has only been stu...

We give a new algorithm to simplify a given triangulation with respect to a given curve. The simplification uses flips together with powers of Dehn twists in order to complete in polynomial time in the bit-size of the curve. keywords. triangulations of surfaces, flip graphs, Dehn twists Mathematics Subject Classification (2010): 57M20
