A new approach to multiframe structure from motion for point features is presented. Unlike previous approaches, it gives robust reconstruction in situations commonly encountered in outdoor robot navigation, for general motion and with large perspective eeects. Under the appropriate conditions, the algorithm prov-ably gives the correct reconstruction. The typical computation time is seconds. It ...

Lineage information is the part of metadata that describes “what”, “when”, “who”, “how”, and “where” geospatial data were generated. If it well-presented queryable, lineage becomes very useful for inferring quality, tracing error sources increasing trust in information. In addition, if a collection datasets can be related presented together, datasets, process chains, methodologies compared. Thi...

Analyzing disperse and heterogeneous provenance data usually requires using higher-level tools which scientists need to learn. In our view, scientists should be able to analyze provenance in the SWfMS of their choice. In this paper, we propose Géfyra, an architecture based on the PROV-Wf model, which provides a way to capture heterogeneous provenance data from different SWfMSs into a single for...

Provenance metadata can be valuable in data sharing settings, where it can be used to help data consumers form judgements regarding the reliability of the data produced by third parties. However, some parts of provenance may be sensitive, requiring access control, or they may need to be simplified for the intended audience. Both these issues can be addressed by a single mechanism for creating a...

A bstract . We investigate the dynam ics of monomial cellular automata, whose next-st ate is given as a product of t he neighb orin g states . Monomial cellular auto mata prov ide a multi plicative analogue of addit ive cellular automata with novel dynamical features. Phase portrait s are given for monomials of degree two and t hree , along with general methods to obtain them. Monomials of high...

Two new species of the genus Stenohya Beier, 1967 are described from China: Stenohya pengaesp. n. (male and female; type locality Daming Mountain, Nanning City, Guangxi Zhuang Autonomous Region) and Stenohya huangisp. n. (female; type locality Gushan Mountain, Fuzhou City, Fujian Prov.).The presence of Stenohya pengaesp. n. in the tree crown of Castanopsis fabri represents a new habitat for Neo...

SHARP is a Linked Data approach for harmonizing cross-workflow provenance. In this demo, we demonstrate SHARP through a real-world omic experiment involving workflow traces generated by Taverna and Galaxy systems. SHARP starts by interlinking provenance traces generated by Galaxy and Taverna workflows and then harmonize the interlinked graphs thanks to OWL and PROV inference rules. The resultin...
