Improving Business Process Visualizations

Ein Ansatz zur Verbesserung von Visualisierung von Geschäftsprozessen wird vorgestellt. Als Modellierungssprache der Prozesse wird BPMN (business process modeling notation) verwendet. Der Ansatz basiert auf einem graph-geometrischen Algorithmus, der einen Schnitt unter Nebenbedingungen auf Visualisierungen in BPMN berechnet. Die inhärente Komplexität der Visualisierungen soll dabei nicht unterdrückt werden. Ebenfalls wird vorgestellt, wie zuvorderst eine Visualisierung für ein Geschäftsprozessmodell in BPMN gefunden werden kann.In this report, we propose an approach of increasing the readability of process visualizations. The approach is based on a graph-geometric algorithm that performs constrained cuts on given visualizations. A side constraint of the approach is not to hide the inherent complexity of the business process. As modeling notation for business processes, the business process modeling notation BPMN is state of the art and it is primarily supported by our approach. We will also show how to find a visualization beforehand

Advanced UVOIR Mirror Technology Development for Very Large Space Telescopes

The Advanced Mirror Technology Development (AMTD) project is in phase 2 of a multiyear effort, initiated in FY 2012. This effort is to mature, by at least a half Technology Readiness Level step, the critical technologies required to enable 4-meter or larger ultraviolet, optical, and infrared (UVOIR) space telescope primary mirror assemblies for both general astrophysics and ultra-high contrast observations of exoplanets. AMTD continues to achieve all of its goals and has accomplished all of its milestones to date. This has been achieved by assembling an outstanding team from academia, industry, and government with extensive expertise in astrophysics and exoplanet characterization, and in the design/manufacture of monolithic and segmented space telescopes; by deriving engineering specifications for advanced normal-incidence mirror systems needed to make the required science measurements; and by defining and prioritizing the most important technical problems to be solved. Our results have been presented to the CoPAG and Mirror Tech Days 2013, and proceedings papers of the 2013 and 2014 SPIE Optics & Photonics Symposia have been published

Opto-Mechanical Failure Detection for Transparent Materials

This disclosure describes techniques for in-situ detection of failures in optical components. Conductive clear coatings, e.g., Indium Tin Oxide (ITO) coatings are applied to optically transparent components. Measurements of resistance or capacitance across the coated layers are utilized for the detection of component failure(s) and/or surface contamination on optical surfaces. ITO is optically transparent and electrically conductive, thereby enabling detection of failures without affecting normal functionality of an optical device. For example, ITO is applied as a trace on a surface of the optical component to form an ITO trace network. Component breakage is detected based on a conductance measurement across the ITO trace network. In some cases, the ITO trace network and conductance measurement system can be applied to all optical surfaces on the component, thereby enabling detection of failures on any of the surfaces of the optical component

GraphArchive - An Online Graph Data Store

In this report, we present our approach 'GraphArchive'. The solution attempts to enable researchers to exchange and archive graphs. The software is developed as an online platform using modern web technologies. In the document, features and architecture of GraphArchive are presented and the former approach 'GraphDB' is compared to the new system. Also, reader are taken on a typical walk through the system using a common use case for GraphArchive. News and development status of the system can be also visited at http://www.graph-archive.org

The Open Graph Archive: A Community-Driven Effort

In order to evaluate, compare, and tune graph algorithms, experiments on well designed benchmark sets have to be performed. Together with the goal of reproducibility of experimental results, this creates a demand for a public archive to gather and store graph instances. Such an archive would ideally allow annotation of instances or sets of graphs with additional information like graph properties and references to the respective experiments and results. Here we examine the requirements, and introduce a new community project with the aim of producing an easily accessible library of graphs. Through successful community involvement, it is expected that the archive will contain a representative selection of both real-world and generated graph instances, covering significant application areas as well as interesting classes of graphs.Comment: 10 page

Forschungsprojekt: Usability-Evaluation von BPMN-konformer Geschäftsprozessmodellierungssoftware

Die Gestaltung effizienter Geschäftsprozesse ist eine zentrale Unternehmensaufgabe, an der heterogene Anspruchsgruppen in verschieden Rollen beteiligt sind. Im Rahmen eines gemeinsamen Forschungsprojekts der Lehrstühle Paralleles Rechnen und Wirtschaftsinformatik der Eberhard Karls Universität Tübingen wurde untersucht, inwieweit Geschäftsprozessmodellierungssoftware Usability-Standards sowohl bei der Modellierung selbst als auch im Hinblick auf das Layout erfüllen und damit den Anforderungen der verschiedenen Nutzertypen an die Gebrauchstauglichkeit gerecht werden.The design of efficient business processes is a central corporate mission where heterogeneous groups of stakeholders participate in different roles. Within the framework of a joint research project of the chairs Parallel Computing and Information Systems at the Eberhard Karls University of Tübingen was examined to what extent business process modeling software meet usability standards - both in the modeling itself and with regard to the layout - and hence fulfilling the usability requirements of different user types

The Development of Stacked Core for the Fabrication of Deep Lightweight UV-Quality Space Mirrors

The 2010 Decadal Survey stated that an advanced large-aperture ultraviolet, optical, near-infrared (UVOIR) telescope is required to enable the next generation of compelling astrophysics and exoplanet science; and, that present technology is not mature enough to affordably build and launch any potential UVOIR mission concept. Under Science and Technology funding, NASA's Marshall Space Flight Center (MSFC) and Exelis have developed a more cost effective process to make 4m class or larger monolithic spaceflight UV quality, low areal density, thermally and dynamically stable primary mirrors. A proof of concept 0.43m mirror was completed at Exelis optically tested at 250K at MSFC which demonstrated the ability for imaging out to 2.5 microns. The parameters and test results of this concept mirror are shown. The next phase of the program includes a 1.5m subscale mirror that will be optically and dynamically tested. The scale-up process will be discussed and the technology development path to a 4m mirror system by 2018 will be outlined

Status of the Advanced Mirror Technology Development (AMTD) Phase 2, 1.5m ULE(Registered Trademark) Mirror

The Decadal Survey stated that an advanced large-aperture ultraviolet, optical, near-infrared (UVOIR) telescope is required to enable the next generation of compelling astrophysics and exoplanet science; and, that present technology is not mature enough to affordably build and launch any potential UVOIR mission concept. Under Science and Technology funding, NASA's Marshall Space Flight Center (MSFC) and Exelis have developed a more cost effective process to make up to 4m monolithic spaceflight UV quality, low areal density, thermally and dynamically stable primary mirrors. Under a Phase I program, a proof of concept mirror was completed at Exelis and tested down to 250K at MSFC which would allow imaging out to 2.5 microns. In 2014, Exelis and NASA started a Phase II program to design and build a 1.5m mirror to demonstrate lateral scalability to a 4m monolithic primary mirror. The current status of the Phase II development program will be provided along with a Phase II program summary
