  • Interoperability Via Mapping Objects
    Interoperability via Mapping Objects Fragkiskos Pentaris and Yannis Ioannidis University of Athens, Dept. of Informatics and Telecommunications Panepistemioupolis, 157 84, Athens, Hellas (Greece) {frank, yannis}@di.uoa.gr 1. Introduction In order to provide end-users with services of better quality, Digital Libraries (DLs) need to be constantly adopting new technologies that are emerging in various related fields, e.g., new metadata models and languages, new information retrieval algorithms, and new storage means. These force DLs to constantly alter their basic structure, generat- ing significant interoperability problems between the new and the old systems. Solving the various semantic, syntactic and structural interoperability issues in large federations of DLs, remains a major problem [8]. Over the years, system designers have developed several different approaches for in- teroperability [12], including the use of (families of) standards, external mediation, speci- fication-based interaction, and mobile functionality. The use of mediation or middleware techniques has gained much support, as it provides good results without compromising the autonomy of existing systems. Recent examples of such DL systems and architectures in- clude MARIAN [3], MIX [1], and the Alexandria Digital Library [4]. Some other relevant, yet more general, systems include Pegasus, Infomaster, TSIMMIS, GARLIC, HERMES, MOCHA, MOMIS, OPM, SIMS/ARIADNE, Information Manifold, Clio, IRO-DB, and MIRO-Web. In this short paper, we give an overview of the HORSE II distributed mediated sys- tem. This system, follows the traditional mediator-wrapper model, combined with several techniques to provide bi-directional (read-write) access to multiple, disparate data sources. Transformations between different forms of data and queries are expressed with the help of volatile mapping objects.

  • Overview of the Incompressible Navier–Stokes Simulation Capabilities in the MOOSE Framework
    Overview of the Incompressible Navier{Stokes simulation capabilities in the MOOSE Framework John W. Peterson, Alexander D. Lindsay, and Fande Kong jw.peterson,alexander.lindsay,fande.kong @inl.gov f g Department of Modeling and Simulation Idaho National Laboratory 2525 N. Fremont Ave. Idaho Falls, ID 83415 February 22, 2018 Abstract The Multiphysics Object Oriented Simulation Environment (MOOSE) framework is a high-performance, open source, C++ finite element toolkit developed at Idaho Na- tional Laboratory. MOOSE was created with the aim of assisting domain scientists and engineers in creating customizable, high-quality tools for multiphysics simulations. While the core MOOSE framework itself does not contain code for simulating any particular physical application, it is distributed with a number of physics \modules" which are tailored to solving e.g. heat conduction, phase field, and solid/fluid mechan- ics problems. In this report, we describe the basic equations, finite element formula- tions, software implementation, and regression/verification tests currently available in MOOSE's navier_stokes module for solving the Incompressible Navier{Stokes (INS) equations. arXiv:1710.08898v2 [math.NA] 21 Feb 2018 1 Introduction The MOOSE framework [1], which has been under development since 2008 and LGPL-2.1 licensed open source software on GitHub1 since March 2014 [2], was originally created to fa- cilitate the development of sophisticated simulation tools by domain experts in fields related to nuclear power generation (neutron transport, nuclear fuel performance, mesoscale mate- rial modeling, thermal hydraulics, etc.) who were not necessarily experts in computational science. A guiding principle in the development of the MOOSE framework is: by lowering the typical computational science-related barriers of entry, e.g.

    TM THRESHOLDVolume 32, No. 4 July/Aug 2016 2016 IEW - ESD Technology Mixed with Bavarian Fun! The 2016 IEW workshop was held at the Evangelische Akademie in Tutzing, Germany, and we continue to receive comments about its success. The workshop was attended by 87 people, making this one of the most popular locations for the IEW. The conference facilities made the event a wonderful experience, with a circular auditorium for talks that created both a relaxed and open environment for the speakers and attendees. The conference included poster sessions and presentations about several ESD related issues. Discussion Groups were quite popular and attendees actively participated. For this workshop there were several invited talks from industries including medical appliances and automotive. On Monday evening, attendees were entertained with Bavarian tradi- tions such as a particular form of dancing called ‘Schuhplattln’. On Wednesday, there was time for everyone to enjoy some of the local scenery. The IEW workshop is proving to be a popular event containing some valuable technical presentations, posters, tutorials, and discussions, while maintaining a relaxed and informal environment. If you would like to be a part of this rewarding event we invite you to join us next year at the 11th annual IEW workshop from May 7-11, 2017 at the Granlibakken Tahoe, Tahoe City, CA.

Trogden All Rights Reserved BRIGHAM YOUNG UNIVERSITY - IDAHO DEPARTMENT APPROVAL of a senior thesis submitted by Tyler S. Trogden This thesis has been reviewed by the research committee, senior thesis coor- dinator, and department chair and has been found to be satisfactory. Date Evan Hansen, Advisor Date Kevin Kelley, Senior Thesis Coordinator Date Richard Hatt, Committee Member Date Lance Nelson, Committee Member Date Todd Lines, Chair ABSTRACT INTRODUCTION TO PHASE FIELD MODELING Tyler S. Trogden Department of Physics Bachelor of Science Phase-field modeling is introduced as a way to simulate grain growth evolution in systems of crystalline solids; this is achieved using MOOSE (Multi-Physics Object Oriented Simulation Environment) which was developed at Idaho Na- tional Laboratory (INL). It has been used to model grain growth of UO2 at INL using an isotropic grain boundary energy model. This paper is a tutorial for students seeking to learn how to read and write input files with MOOSE syntax in order to test modifications that include anisotropic grain boundary energies. ACKNOWLEDGMENTS I would be remise if I did not thank all of my professors who sacrificed their time to help mold this paper into the work that it has become, and for blessing me with the opportunity to grow and stretch by challenging me to go further than I knew I could.
