    A Model-Driven Engineering Approach for ROS using Ontological Semantics

    Full text link
    This paper presents a novel ontology-driven software engineering approach for the development of industrial robotics control software. It introduces the ReApp architecture that synthesizes model-driven engineering with semantic technologies to facilitate the development and reuse of ROS-based components and applications. In ReApp, we show how different ontological classification systems for hardware, software, and capabilities help developers in discovering suitable software components for their tasks and in applying them correctly. The proposed model-driven tooling enables developers to work at higher abstraction levels and fosters automatic code generation. It is underpinned by ontologies to minimize discontinuities in the development workflow, with an integrated development environment presenting a seamless interface to the user. First results show the viability and synergy of the selected approach when searching for or developing software with reuse in mind.Comment: Presented at DSLRob 2015 (arXiv:1601.00877), Stefan Zander, Georg Heppner, Georg Neugschwandtner, Ramez Awad, Marc Essinger and Nadia Ahmed: A Model-Driven Engineering Approach for ROS using Ontological Semantic

    Aorto-subclavian thromboembolism: a rare complication associated with moderate ovarian hyperstimulation syndrome

    The case of an arterial aorto-subclavian thromboembolism associated with a moderate ovarian hyperstimulation syndrome (OHSS) and following ovulation induction for in-vitro fertilization in a young woman is reported. Because of the lack of response to systemic thrombolysis, a left postero-lateral thoracotomy was performed on day 8 after embryo transfer. A fibrinocruoric embolus situated at the junction of the left subclavian artery from the aorta was removed through a left subclavian arteriotomy. The distal axillary embolus was removed by a retrograde balloon catheter embolectomy. A moderate OHSS was observed. The ovarian stimulation and OHSS-related risks of thromboembolism are discussed. We conclude that, in the absence of risk factors, counselling about possible complications resulting from stimulation must be emphasize

    Science from an Ultra-Deep, High-Resolution Millimeter-Wave Survey

    Opening up a new window of millimeter-wave observations that span frequency bands in the range of 30 to 500 GHz, survey half the sky, and are both an order of magnitude deeper (about 0.5 uK-arcmin) and of higher-resolution (about 10 arcseconds) than currently funded surveys would yield an enormous gain in understanding of both fundamental physics and astrophysics. In particular, such a survey would allow for major advances in measuring the distribution of dark matter and gas on small-scales, and yield needed insight on 1.) dark matter particle properties, 2.) the evolution of gas and galaxies, 3.) new light particle species, 4.) the epoch of inflation, and 5.) the census of bodies orbiting in the outer Solar System.Comment: 5 pages + references; Submitted to the Astro2020 call for science white paper

    Material Codes: Ephemeral Traces

    No full text
    New forms of digital imaging such as GPS and satellite mapping have had significant impact on our collective senses of orientation in space and time. Similarly, digital software such as that used for Jacquard weaving allow for new forms of collage, superimposing, combining, repetition, and fragmenting of imagery, which further disrupt a stable perspective. This article links concepts of global data circulation and collection with contemporary data visualization and materialization approaches in the field of digital humanities. Kelly Thompson’s multifaceted project Material Codes: Ephemeral Traces, established in 2014, translates various forms of data through digitally assisted Jacquard weaving. With data visualization, the artist’s subjective process of beautification can make an audience feel emotionally engaged by the rendering of phenomena that may otherwise be beyond the scale of human senses. What is beyond reach becomes tangible. In Thompson’s research-creation work, the intangible concept of digital data is both visualized and materialized into the literally tangible, as tactile cloth. This conversation between Janis Jefferies, (London, UK) and Kelly Thompson (Montreal, Canada) over a period of 10 months proposes questions around code, data, image, weaving, and research engagement
