Extensions to Metadata Languages for Environmental Primary Data: the Forest Cloud Extensions to Metadata Languages for Environmental Primary Data: the Forest Cloud By Luis Maria Ibanez de Garayo Adissertationsubmittedinpartialsatisfactionofthe requirements for the degree of Doctor of Philosophy in Environmental Science , Policy, and Management in the Graduate Division of the University of California, Berkeley Committee in Charge: Professor Greg Biging, Chair Professor Ray Larson Professor Dennis Baldocchi Fall 2011 para mis grandes amores for their support and comprehension Barbara ,Maite, eta Robertorentzat, nere ondoan egoteagatik eta emandako indar eta maitasun guztiagatik. Maite zaituztet Abstract During the last decade environmental scientists and managers have found in the Internet a new communication venue that has improved their productivity by allowing them to share data and knowledge more fluently. Since the invention of the eXtensible Markup Lan- guage (XML), XML has brought the attention of many researchers to improve the communications among people working with data-centric documents since XML was supposed to be the correct approach to standardize data. During this decade, many papers have been pub- lished under the pretenses of XML being the new and paradigmatic standard to share data even though no study has proved that the XML languages have been used by researchers or managers working with data-centric documents during this period of time. This thesis by researching all possible spaces proves that, on the contrary, that after more than a decade from its invention, XML is still not used by the vast scientific community that works with data-centric documents who are still using data archives with legacy formats. Therefore, if data stan- dardization is difficult to attain, and facilitating sharing data a goal to reach, the other clear venue to follow to achieve the goal is to use metadata information. However, metadata languages such as the Eco- logical Modeling Language (EML) and others have no intrinsic features to complete and directly describe the information conveyed in many important types of data-centric documents used by environmentalists. By carefully studying the nature of data-centric archives and the pro- cess of metadata creation, this thesis shows that any data archive can be easily described using an “a posteriori” approach where the lexical descriptors of the physical data from a data-centric file are developed by inspection of the file instead of by following the specifications of the format of the file. In addition, following the principles of the Linked Open Data project, the lexical tree is mapped into a simple logic model with semantic annotations from controlled vocabularies which can be easily serialized for data exchange or data syndicalization. With the metadata extensions researched in this thesis, metadata languages such as EML can be improved by increasing its expression power. Environ- mental scientists and researchers can us this to exchange data-centric documents, and multidisciplinary projects can easily syndicate data from different authors in different formats in a data-centric cloud. i Preface Ten years ago while learning about renewable forest resources and having known first hand and read about unscrupulous forest operations, I had a dream of a new forest regime where the information about forest operations could travel through the Internet free of any impedance with contrasted and true information. With this thesis, I have tried to pave the road for a better Internet. However this thesis could no have been materialized without the support of my wife who for eighteen long years has supported me and our family every single day of the trip. My thanks also go to all people that with their writings and tools have enlighten my ideas and work. Special thanks to my professors for their infinite patience and my apologies to them for my lack of communication skills. I thank Prof. Larson for teaching me the power of databases and his willingness to listen my ideas every time I stepped into his office, to Prof. Baldocchi for showing me his enthusiasm, the multidisciplinary nature of environmental sciences and the ubiquitous need of sharing primary datasets for the good of the people and their environment, to Prof. Tim Berners-Lee and Prof. Goodchild for having the time to read my spam-like email without knowing me and support my ideas and given me interesting feedback, and last but not least, to Prof. Biging for believing in me and taking me under his wing to the very very very last day. To all of you I thank again from the bottom of my heart.

  • Dynamic Generation of Musical Notation from Musicxml Input on an Android Tablet
    Dynamic Generation of Musical Notation from MusicXML Input on an Android Tablet THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Laura Lynn Housley Graduate Program in Computer Science and Engineering The Ohio State University 2012 Master's Examination Committee: Rajiv Ramnath, Advisor Jayashree Ramanathan Copyright by Laura Lynn Housley 2012 Abstract For the purpose of increasing accessibility and customizability of sheet music, an application on an Android tablet was designed that generates and displays sheet music from a MusicXML input file. Generating sheet music on a tablet device from a MusicXML file poses many interesting challenges. When a user is allowed to set the size and colors of an image, the image must be redrawn with every change. Instead of zooming in and out on an already existing image, the positions of the various musical symbols must be recalculated to fit the new dimensions. These changes must preserve the relationships between the various musical symbols. Other topics include the laying out and measuring of notes, accidentals, beams, slurs, and staffs. In addition to drawing a large bitmap, an application that effectively presents sheet music must provide a way to scroll this music across a small tablet screen at a specified tempo. A method for using animation on Android is discussed that accomplishes this scrolling requirement. Also a generalized method for writing text-based documents to describe notations similar to musical notation is discussed. This method is based off of the knowledge gained from using MusicXML.

  • Trusted Computing Or Distributed Trust Management?
    Trusted computing or distributed trust management? Michele Tomaiuolo Dipartimento di Ingegneria dell’Informazione Università di Parma Via Usberti, 181/A – 43100 Parma – Italy [email protected] Abstract Nowadays, in contrast with centralized or hierarchical certification authorities and directory of names, other solutions are gaining momentum. Federation of already deployed security systems is considered the key to build global security infrastructures. In this field, trust management systems can play an important role, being based on a totally distributed architecture. The idea of distributed trust management can be confronted with the concept of trusted computing. Though having a confusingly similar denomination, the different interpretation of trust in these systems drives to divergent consequences with respect to system architectures and access policies, but also to law, ethics, politics. While trusted computing systems assure copyright holders and media producers that the hosting system will respect the access restrictions they defined, trust management systems, instead, allow users to grant trust to other users or software agents for accessing local resources. Keywords Data security, Security Management, Authentication, Authorization, Intellectual Property Rights, Information Access, Digital Books, Multimedia, Web Technologies Introduction A number of architectures and systems are being proposed as a ground for improved interoperability among diverse systems, mainly exploiting the idea of service-oriented architecture. Yet, some issues remain open. In fact, composition of services requires some delegation of goals and duties among partners. But these delegations cannot come into effect, if they’re not associated with a corresponding delegation of privileges, needed to access some resources and complete delegated tasks, or achieve desired goals.

  • Designing Universal Chemical Markup (UCM) Through the Reusable Methodology Based on Analyzing Existing Related Formats
    Designing Universal Chemical Markup (UCM) through the reusable methodology based on analyzing existing related formats Background: In order to design concepts for a new general-purpose chemical format we analyzed the strengths and weaknesses of current formats for common chemical data. While the new format is discussed more in the next article, here we describe our software s t tools and two stage analysis procedure that supplied the necessary information for the n i r development. The chemical formats analyzed in both stages were: CDX, CDXML, CML, P CTfile and XDfile. In addition the following formats were included in the first stage only: e r P CIF, InChI, NCBI ASN.1, NCBI XML, PDB, PDBx/mmCIF, PDBML, SMILES, SLN and Mol2. Results: A two stage analysis process devised for both XML (Extensible Markup Language) and non-XML formats enabled us to verify if and how potential advantages of XML are utilized in the widely used general-purpose chemical formats. In the first stage we accumulated information about analyzed formats and selected the formats with the most general-purpose chemical functionality for the second stage. During the second stage our set of software quality requirements was used to assess the benefits and issues of selected formats. Additionally, the detailed analysis of XML formats structure in the second stage helped us to identify concepts in those formats. Using these concepts we came up with the concise structure for a new chemical format, which is designed to provide precise built-in validation capabilities and aims to avoid the potential issues of analyzed formats.

  • Linking Nwchem and Avogadro with the Syntax and Semantics of Chemical Markup Language Wibe a De Jong1*†, Andrew M Walker2† and Marcus D Hanwell3†
    de Jong et al. Journal of Cheminformatics 2013, 5:25 http://www.jcheminf.com/content/5/1/25 RESEARCH ARTICLE Open Access From data to analysis: linking NWChem and Avogadro with the syntax and semantics of Chemical Markup Language Wibe A de Jong1*†, Andrew M Walker2† and Marcus D Hanwell3† Abstract Background: Multidisciplinary integrated research requires the ability to couple the diverse sets of data obtained from a range of complex experiments and computer simulations. Integrating data requires semantically rich information. In this paper an end-to-end use of semantically rich data in computational chemistry is demonstrated utilizing the Chemical Markup Language (CML) framework. Semantically rich data is generated by the NWChem computational chemistry software with the FoX library and utilized by the Avogadro molecular editor for analysis and visualization. Results: The NWChem computational chemistry software has been modified and coupled to the FoX library to write CML compliant XML data files. The FoX library was expanded to represent the lexical input files and molecular orbitals used by the computational chemistry software. Draft dictionary entries and a format for molecular orbitals within CML CompChem were developed. The Avogadro application was extended to read in CML data, and display molecular geometry and electronic structure in the GUI allowing for an end-to-end solution where Avogadro can create input structures, generate input files, NWChem can run the calculation and Avogadro can then read in and analyse the CML output produced. The developments outlined in this paper will be made available in future releases of NWChem, FoX, and Avogadro. Conclusions: The production of CML compliant XML files for computational chemistry software such as NWChem can be accomplished relatively easily using the FoX library.

  • JSON Application Programming Interface for Discrete Event Simulation Data Exchange
    JSON Application Programming Interface for Discrete Event Simulation data exchange Ioannis Papagiannopoulos Enterprise Research Centre Faculty of Science and Engineering Design and Manufacturing Technology University of Limerick Submitted to the University of Limerick for the degree of Master of Engineering 2015 1. Supervisor: Prof. Cathal Heavey Enterprise Research Centre University of Limerick Ireland ii Abstract This research is conducted as part of a project that has the overall aim to develop an open source discrete event simulation (DES) platform that is expandable, and modular aiming to support the use of DES at multi-levels of manufacturing com- panies. The current work focuses on DES data exchange within this platform. The goal of this thesis is to develop a DES exchange interface between three different modules: (i) ManPy an open source discrete event simulation engine developed in Python on the SimPy library; (ii) A Knowledge Extraction (KE) tool used to populate the ManPy simulation engine from shop-floor data stored within an Enterprise Requirements Planning (ERP) or a Manufacturing Execution System (MES) to allow the potential for real-time simulation. The development of the tool is based on R scripting language, and different Python libraries; (iii) A Graphical User Interface (GUI) developed in JavaScript used to provide an interface in a similar manner to Commercial off-the-shelf (COTS) DES tools. In the literature review the main standards that could be used are reviewed. Based on this review and the requirements above, the data exchange format standard JavaScript Object Notation (JSON) was selected. The proposed solution accom- plishes interoperability between different modules using an open source, expand- able, and easy to adopt and maintain, in an all inclusive JSON file.
