Engineering Support Systems for Industrial Machines and Plants

In the business of industrial machines and plants, rapid and detailed estimates for planning installation, replacement of equipment, or maintenance work are key requirements for meeting the demands for greater reliability, lower costs and for maintaining safe and secure operation. These demands have been addressed by developing technology driven by IT. When replacing equipment at complex building or plants with high equipment density, the existing state of the installation locations and transportation routes for old and new equipment need to be properly measured. We have met this need by developing parts recognition technology based on 3D measurement, and by developing high-speed calculation technology of optimal routes for installation parts. This chapter provides an overview of these development projects with some real business application results

Response to disruptive innovation with hybrid products: transition of Oracle's business applications to cloud computing

Success and failure of the incumbent's response to disruptive technologies have been in the focus of innovation and strategy research for decades. Recent papers have suggested that developing a hybrid product, which combines old and new technology, can be a stepping stone towards fully embracing new technology. This paper explores the role of hybrid products in the response of Oracle Corporation, to cloud computing, a disruptive innovation. The development of a hybrid product allowed Oracle to successfully transition its business applications to a cloud offering while not abandoning the needs of its customers with respect to traditional products. The findings show that changing the positioning of a hybrid product by moving the focus from old technology entirely to the new can support an evolving response to disruptive innovation. The paper also considers the implication of cloud computing on Oracle's business in emerging countries

Infraestructuras de datos espaciales tridimensionales: hacia un modelo real de la información geográfica

[ES] Esta tesis doctoral desarrolla un completo análisis de la situación actual de las IDE con respecto a la tercera dimensión, abordando líneas de investigación a futuro y analizando las necesidades y debilidades que se presentan. Tras profundizar en los conocimientos sobre IDE a través del máster en Geotecnologías cartográficas en Ingeniería y Arquitectura de la Universidad de Salamanca y, tras comprobar tanto la necesidad como la convergencia de diversas ramas técnico-científicas en materia de gestión de información geográfica (IG) tridimensional, se decide, a través de este trabajo desarrollar un proyecto de investigación centrado en las IDE 3D. Siguiendo un enfoque cualitativo en el desarrollo de la metodología de investigación, se hace patente la importancia de lo que supone la tercera dimensión espacial para el desempeño de las actividades cotidianas del ser humano en nuestros tiempos. El análisis de las encuestas y entrevistas realizadas con especialistas prestigiosos en este campo ponen de manifiesto la necesidad de promover la investigación y el desarrollo tecnológico en el ámbito de las IDE 3D y de los servicios que deben acompañar a las mismas. Finalmente, se definen los elementos necesarios para poder implementar una IDE tridimensional, teniendo en cuenta todos los parámetros de desarrollo, tanto técnicos como legales, necesarios para cumplir con los actuales marcos tecnológicos, normativos, jerárquicos y legales. A través del trabajo desarrollado, se pone de manifiesto la existencia de una gran cantidad de iniciativas, que con carácter experimental han surgido para solucionar las carencias en lo relativo a la gestión y publicación de IG tridimensional. Se ha constatado que, por lo general, la adaptación de la tercera dimensión por parte de las IDE está en fase germinal, con muchas posibilidades de avance y aporte de contribuciones científicas y tecnológicas. Este documento intenta ser una de esas contribuciones.[EN] This doctoral thesis develops a complete analysis of the current situation of SDI with respect to the third dimension, addressing future research lines and analysing the needs and weaknesses that are presented. After deepening the knowledge on SDI through the master in Cartographic Geotechnologies in Engineering and Architecture at the University of Salamanca and, after checking both the need and the convergence of diverse technical-scientific branches in the matter of three-dimensional geographic information (GI) management, it is decided, through this work, to develop a research project focused on 3D SDI. Following a qualitative approach in the development of the research methodology, it becomes clear the importance of what the third space dimension represents for the performance of the daily activities of the human being in our days. The analysis of surveys and interviews with prestigious specialists in this field show the need to promote research and technological development in the field of 3D SDI and the services that must accompany them. Finally, the necessary elements are defined to be able to implement a three-dimensional SDI, taking into account all the development parameters, both technical and legal, necessary to comply with the current technological, normative, hierarchical and legal frameworks. Through the work developed, the existence of a large number of initiatives, which have emerged experimentally to solve the shortcomings in the management and publication of three-dimensional GI, is revealed. It has been observed that, generally, the adaptation of the third dimension by SDI is in the germinal phase, with many possibilities of advancement and scientific and technological contributions. This document aims to be one of these contributions

Our thesis work focuses on collaborative 3D GIS and considers two main aspects governing their implementation: a conceptual framework for an approach to design these systems and a technical framework dealing with the main issues of integration of multiple data sources from different partners in a 3D collaborative database

Automatisierte Bestimmung von Schüttgutvolumen aus Punktwolken

Ziel dieser Diplomarbeit ist es, eine Software zu entwickeln, welche den Benutzer bei der Volumenberechnung aus Punktwolken unterstützt. Dazu werden verschiedene Methoden diskutiert, mit deren Hilfe eine Trennung der Punktwolke in zwei Klassen ('gehört zur Volumenoberfläche' und 'gehört nicht zur Volumenoberfläche') möglich ist. Eine Methode stellt sich, unter bestimmten Bedingungen, als geeignet dar. Mit dieser Methode lässt sich die geforderte Klassifizierung effizient durchführen. Weiterhin gilt es, für die eigentliche Volumenberechnung, Methoden zu analysieren und auf deren Tauglichkeit für die Anwendung in der Punktwolke zu prüfen. Aus diesen Ergebnissen wird ein Verfahren zur Klassifizierung der Scanpunkte und direkt anschließender Volumenmodellerstellung erarbeitet. Die Darstellung des Volumens ist an vorgegebene Rahmenbedingungen, das Verwenden einer bestimmten CAD-Software, gebunden. Mit Hilfe dieser CAD-Software ist eine Darstellungsvariante zu wählen, welche ein zügiges Arbeiten mit dem Volumenmodell ermöglicht. Alle Verfahren und Methoden, einschließlich der dabei auftretenden Probleme werden in Programmcode umgesetzt, damit am Ende eine funktionsfähige, unterstützende Software entsteht.:1 Einleitung 1.1 Thesen / Fragen 1.2 Literatur 1.3 Abgrenzung 2 Grundlagen 2.1 Rahmenbedingungen 2.2 Struktur des Programmierprojektes 2.2.1 Speicherung von Einstellungen / Parametern 2.3 Datengrundlage 2.3.1 Dateiformate der Punktwolkendateien 3 Filterung der Punktwolke 3.1 Das Voxelsystem 3.1.1 Programmierung des Voxelsystems 3.1.2 Speicherung der Voxeldaten 3.2 Filterung mit Hilfe des Voxelsystem 4 Volumenberechnungen 4.1 Erläuterung der verwendeten Säulenprismen 4.1.1 Rasterung der Grundfläche 4.1.2 Umsetzung des Texelsystems als Quadtree 4.2 Einsatz des Texelsystem in der Volumenberechnung 4.2.1 Speicherung der Volumendaten 4.3 Darstellung der Volumendaten 5 Bearbeitungen der Volumendaten 5.1 Füllen von Löchern in der Volumenfläche 5.2 Glätten von Bereichen 6 Die Software in Gänze betrachtet 6.1 Analyse der Effektivität 6.2 Ausblick und AusbauThe intention of this thesis is to develop a software which supports the user in calculating volumes from point clouds. For this purpose, different methods are discussed that allow a separation of the point cloud into two classes (i.e. 'belongs to the volume surface' and 'does not belong to the volume surface'). One method is shown to be suitable under certain conditions. With this method, the required classification can be carried out efficiently. Furthermore, methods for the volume calculation itself are analyzed and tested to ensure that they are suitable for use in the point cloud. Based on these results, a method for the classification of the scan points and the ensuing generation of the volume model are developed. The representation of the volume is bound to given framework conditions, including the use of a specific CAD software. With the help of this CAD software, a representation variant is to be selected which enables a user to easily work with the volume model. All procedures and methods, including the problems that arise in the process, are converted into program code, so that in the end a functional, helpful software is created.:1 Einleitung 1.1 Thesen / Fragen 1.2 Literatur 1.3 Abgrenzung 2 Grundlagen 2.1 Rahmenbedingungen 2.2 Struktur des Programmierprojektes 2.2.1 Speicherung von Einstellungen / Parametern 2.3 Datengrundlage 2.3.1 Dateiformate der Punktwolkendateien 3 Filterung der Punktwolke 3.1 Das Voxelsystem 3.1.1 Programmierung des Voxelsystems 3.1.2 Speicherung der Voxeldaten 3.2 Filterung mit Hilfe des Voxelsystem 4 Volumenberechnungen 4.1 Erläuterung der verwendeten Säulenprismen 4.1.1 Rasterung der Grundfläche 4.1.2 Umsetzung des Texelsystems als Quadtree 4.2 Einsatz des Texelsystem in der Volumenberechnung 4.2.1 Speicherung der Volumendaten 4.3 Darstellung der Volumendaten 5 Bearbeitungen der Volumendaten 5.1 Füllen von Löchern in der Volumenfläche 5.2 Glätten von Bereichen 6 Die Software in Gänze betrachtet 6.1 Analyse der Effektivität 6.2 Ausblick und Ausba

Octree-based indexing for 3D pointclouds within an Oracle Spatial DBMS

Transportation Research Board 89th Annual MeetingA large proportion of today's digital datasets have a spatial component. The effective storage and management of which poses particular challenges, especially with light detection and ranging (LiDAR), where datasets of even small geographic areas may contain several hundred million points. While in the last decade 2.5-dimensional data were prevalent, true 3-dimensional data are increasingly commonplace via LiDAR. They have gained particular popularity for urban applications including generation of city-scale maps, baseline data disaster management, and utility planning. Additionally, LiDAR is commonly used for flood plane identification, coastal-erosion tracking, and forest biomass mapping. Despite growing data availability, current spatial information systems do not provide suitable full support for the data's true 3D nature. Consequently, one system is needed to store the data and another for its processing, thereby necessitating format transformations. The work presented herein aims at a more cost-effective way for managing 3D LiDAR data that allows for storage and manipulation within a single system by enabling a new index within existing spatial database management technology. Implementation of an octree index for 3D LiDAR data atop Oracle Spatial 11g is presented, along with an evaluation showing up to an eight-fold improvement compared to the native Oracle R-tree index.Deposited by bulk impor

Urban Informatics

This open access book is the first to systematically introduce the principles of urban informatics and its application to every aspect of the city that involves its functioning, control, management, and future planning. It introduces new models and tools being developed to understand and implement these technologies that enable cities to function more efficiently – to become ‘smart’ and ‘sustainable’. The smart city has quickly emerged as computers have become ever smaller to the point where they can be embedded into the very fabric of the city, as well as being central to new ways in which the population can communicate and act. When cities are wired in this way, they have the potential to become sentient and responsive, generating massive streams of ‘big’ data in real time as well as providing immense opportunities for extracting new forms of urban data through crowdsourcing. This book offers a comprehensive review of the methods that form the core of urban informatics from various kinds of urban remote sensing to new approaches to machine learning and statistical modelling. It provides a detailed technical introduction to the wide array of tools information scientists need to develop the key urban analytics that are fundamental to learning about the smart city, and it outlines ways in which these tools can be used to inform design and policy so that cities can become more efficient with a greater concern for environment and equity
