DFL designer

Jacek Sroka, Piotr Włodarczyk, Łukasz Krupa, Jan Hidders
2010 Proceedings of the 1st International Workshop on Workflow Approaches to New Data-centric Science - Wands '10  
The notations, models and techniques used for the construction of COSW tools are similar to the ones known from workflow modeling, but additional emphasis is put on the data manipulation aspects, e.g.,  ...  Petri nets and the nested relational calculus (NRC).  ...  Acknowledgments: The authors thank Lukasz Krupa and Paolo Missier for their contribution to the implementation.  ...

Querying an Integrated Complex-Object Dataflow Database [chapter]

Natalia Kwasnikowska, Jan Van den Bussche
2013 Lecture Notes in Computer Science  
Dataflow specifications are expressed in a high-level programming language based on the nested relational calculus, the operators of which provide the right "glue" needed to combine different service calls  ...  We discuss how such dataflow repositories can be queried in a variety of ways, including provenance queries.  ...  Note that in our previous paper [29] we have given a conversion from our execution model to the proposed standard Open Provenance Model [30] , which uses an explicit causality graph.  ...

Data Lineage Model for Taverna Workflows with Lightweight Annotation Requirements [chapter]

Paolo Missier, Khalid Belhajjame, Jun Zhao, Marco Roos, Carole Goble
2008 Lecture Notes in Computer Science  
is due to one of the authors (Marco Roos).  ...  The provenance, or lineage, of a workflow data product can be reconstructed by keeping a complete trace of workflow execution.  ...  A mapping of the Taverna lineage model to the Open Provenance Model is also in the plans.  ...

Annotated XML

J. Nathan Foster, Todd J. Green, Val Tannen
2008 Proceedings of the twenty-seventh ACM SIGMOD-SIGACT-SIGART symposium on Principles of database systems - PODS '08  
Each of these applications builds on our semantics for XQuery, which we present in several steps: we generalize the semantics of the Nested Relational Calculus (NRC) to handle semiring-annotated complex  ...  In addition to tracking provenance metadata, the framework can be used to represent and process XML with repetitions, incomplete XML, and probabilistic XML, and provides a basis for enforcing access control  ...  Acknowledgements We are grateful to Tova Milo for suggesting that we compare our first semantics with the "shredding" one.  ...

Provenance Traces [article]

James Cheney, Umut Acar, Amal Ahmed
2008 arXiv   pre-print
We show that three pre-existing forms of provenance for the NRC can be extracted from provenance traces.  ...  We introduce provenance traces, a general form of provenance for the nested relational calculus (NRC), a core database query language.  ...  Acknowledgments We gratefully acknowledge travel support from the UK e-Science Institute Theme Program on Principles of Provenance for visits by Acar to the University of Edinburgh and Cheney to Toyota  ...

Probability Grid Mapping system for aerial search

Muna Shabaneh, Sion Jennings, Abdullah Merei, Robert S. Allison
2009 2009 IEEE Toronto International Conference Science and Technology for Humanity (TIC-STH)  
The Probability Grid Mapping system (PGM) is unique in that it aims to improve the effectiveness of the other officer in the aircraft who is managing and performing the tactical mission.  ...  To evaluate the system prior to flight test, a simulation environment was developed for study of the effectiveness of highlighting methods, update strategies, and probability mapping methods.  ...  The terrain map is converted to UTM Cartesian system coordinates for registration purposes. " Fig. 5 " illustrates the head pose estimation dataflow C.  ...

Sub-image data processing in Astro-WISE

Johnson Mwebaze, Danny Boxhoorn, John McFarland, Edwin A. Valentijn
2012 Experimental astronomy (Print)  
The architecture enables a user to select, retrieve and process only the relevant pixels in an image where the source exists.  ...  We show that lineage data collected during the processing and analysis of datasets can be reused to perform selective reprocessing (at subimage level) on datasets while the remainder of the dataset is  ...  Research Council (NRC) of Canada, the Institut National des Science de l'Univers of the Centre National de la Recherche Scientifique (CNRS) of France, and the University of Hawaii.  ...

Application of Machine Learning to Solid Particle Erosion of APS-TBC and EB-PVD TBC at Elevated Temperatures

Yuan Liu, Ravi Ravichandran, Kuiying Chen, Prakash Patnaik
2021 Coatings  
The results suggest that neural networks using the BR model and GBR have better prediction capability.  ...  Following test data collection, the dataset is subjected to sorting, filtering, extracting, and exploratory analysis. The training and testing, and prediction results are analysed.  ...  In addition, some efforts have been made to explore the possibility of the application of DL approaches to the microstructure characterisation of TBCs. 1.  ...

Data Stewardship: Environmental Data Curation and a Web-of-Repositories

Karen S. Baker, Lynn Yarmey
2009 International Journal of Digital Curation  
Through the lens of environmental data stewardship, we consider the data repository as an organizational element central to data curation.  ...  The concept of "sphere-of-context" is introduced as an aid to distinguishing repository types.  ...  We acknowledge the contributions of Helena Karasti in foregrounding the experience of Information Managers and Florence Millerand in following the data as well as the roles associated with the data.  ...
