A Photogrammetry Program for Physical Modeling of Subsurface Subsidence Process

Safe and economic longwall coal extraction requires a good knowledge of overburden strata characteristics and understanding of overburden strata movement in response to the full extraction mining. Subsidence induced overburden movement will affect overlying mining, surface and subsurface water bodies, and methane emission and migration in the overburden strata. Therefore, an understanding of subsurface strata movement is essential for optimal layout of multiple seam mining, protecting water resources, and designing of gob hole patterns for longwall degasification.;Physical simulation experiments play an important role in mining engineering research by allowing visual observations of strata movement in the mining process. In recent years, the advantage physical simulations has supplemented to weakness of computer simulation in some aspects. Some advanced research results in ground control have been obtained through physical simulation, and the findings include key hinged-beam theory, the formation of fractured zones with different permeability in overlying strata.;To improve the method of obtaining and processing measured data during a simulation experiment, a photogrammetry program for capturing and processing the data from physical modeling of mine subsurface subsidence has been developed. The program can capture the observation or measurement points accurately by simply clicking a mouse on an image of the experiment. Four point geometric affine transformation was used in the program to make corrections to images with relation to the camera\u27s change of position over the experiment process. Finally, the program can generate the subsurface subsidence database and export to an spreadsheet file for further data analysis. Subsurface displacement, horizontal strain, and void ratio can then obtained from the data generated by the program. Overall, the program provides an alternative, rapid approach to capturing and processing subsurface subsidence data from a physical simulation model, and introduces a new way to help minimize the error brought by both human and measurement devices

RKWard: A Comprehensive Graphical User Interface and Integrated Development Environment for Statistical Analysis with R

R is a free open-source implementation of the S statistical computing language and programming environment. The current status of R is a command line driven interface with no advanced cross-platform graphical user interface (GUI), but it includes tools for building such. Over the past years, proprietary and non-proprietary GUI solutions have emerged, based on internal or external tool kits, with different scopes and technological concepts. For example, Rgui.exe and Rgui.app have become the de facto GUI on the Microsoft Windows and Mac OS X platforms, respectively, for most users. In this paper we discuss RKWard which aims to be both a comprehensive GUI and an integrated development environment for R. RKWard is based on the KDE software libraries. Statistical procedures and plots are implemented using an extendable plugin architecture based on ECMAScript (JavaScript), R, and XML. RKWard provides an excellent tool to manage different types of data objects; even allowing for seamless editing of certain types. The objective of RKWard is to provide a portable and extensible R interface for both basic and advanced statistical and graphical analysis, while not compromising on flexibility and modularity of the R programming environment itself

Graphical Tool for Image Processing Applications Creation

Tato diplomová práce se zabývá vytvořením nástroje pro vizuální tvorbu aplikací ve zpracování obrazu, které se provádí pomocí grafického propojování funkčních bloků. Grafické propojování je realizováno pomocí tzv. node editoru, který je implementován v Qt frameworku.

Graphical interconnection is realised by so-called node editor that is implemented in Qt framework. This framework is used across the project - for the user interface and management of dynamic libraries. OpenCV library is used as the basis for image processing, this tool can be extended to other methods of image processing using plugins included in the dynamic libraries. The tool interprets the proposed application, the proposal application is supported by the preview mode of the change in real time. The tool also contains a history of actions (Undo/Redo system).

Software to convert terrestrial LiDAR scans of natural environments into photorealistic meshes

The introduction of 3D scanning has strongly influenced environmental sciences. If the resulting point clouds can be transformed into polygon meshes, a vast range of visualisation and analysis tools can be applied. But extracting accurate meshes from large point clouds gathered in natural environments is not trivial, requiring a suite of customisable processing steps. We present Habitat3D, an open source software tool to generate photorealistic meshes from registered point clouds of natural outdoor scenes. We demonstrate its capability by extracting meshes of different environments: 8,800 m2 grassland featuring several Eucalyptus trees (combining 9 scans and 41,989,885 data points); 1,018 m2 desert densely covered by vegetation (combining 56 scans and 192,223,621 data points); a well-structured garden; and a rough, volcanic surface. The resultant reconstructions accurately preserve all spatial features with millimetre accuracy whilst reducing the memory load by up to 98.5%. This enables rapid visualisation of the environments using off-the-shelf game engines and graphics hardware

Conception d'un logiciel de contrôle pour la plate-forme de prototypage waferboard TM

RÉSUMÉ L’évolution des domaines de l’électronique donne naissance à des circuits toujours plus complexes. Les phases de conception et de prototypage représentent une partie importante du coût de développement des produits. Le projet DreamWafer porte sur le prototypage rapide de systèmes électroniques. Il tente de proposer une nouvelle approche au prototypage et à la vérification fonctionnelle de systèmes électroniques, ce qui réduit ainsi leurs coûts de développement et les temps d’arrivé sur le marché. La plateforme s’appuie sur un circuit intégré à l’échelle de la tranche de silicium pour proposer l’équivalent d’un PCB reconfigurable. Une mer de contacts assure la connexion avec les composants déposés par l’usager sur la tranche de silicium et un réseau d’interconnexions configurables permet d’obtenir des routes équivalentes aux pistes de cuivre entre les billes des composants. L’objectif général du projet de recherche présenté ici consiste à concevoir le logiciel nécessaire au support d’une telle plateforme. Le projet comprend l’élaboration d’une architecture générale favorisant l’intégration des ressources techniques existantes (comme les algorithmes de routage), la conception d’une architecture évolutive simplifiant les accès au matériel, et la réalisation d’un système d’affichage adapté à la complexité d’une telle plateforme. Cette conception doit se faire dans un environnement technique bipolaire (électronique et logiciel) connaissant un renouvellement important des personnes intervenant dans le projet. L’architecture développée au cours de ces travaux est conçue pour prendre en charge les contraintes liées au pilotage de la plateforme électronique et de les isoler pour simplifier l’intégration matériel-logiciel et les développements à venir. Ce travail à fait l’objet d’un chapitre soumis pour le livre « Novel Advances in Microsystems Technologies and their Applications ». À cette architecture s’ajoute une contribution technique publiée à la conférence CCECE 2013 (Canadian Conference on Electrical and Computer Engineering) dont l’objectif est de permettre l’affichage rapide du grand volume de données requis pour la représentation d’une telle plateforme.---------- ABSTRACT Electronic system design methods are in constant evolution with access to technologies enabling the creation of increasingly complex circuits. The design and prototyping phases of today’s systems represent a significant part of the overall cost of many products. The DreamWafer project attempts to propose a new approach to the rapid prototyping of Printed Circuit Board, reducing costs and delays. The platform is based on a wafer-scale silicon integrated circuit that works as a reconfigurable PCB. A sea of contacts on its top surface provides the connections with the user components deposited on it and a configurable interconnection network is used to create routes as in a traditional PCB. We present the software written to support this platform. The project includes the development of general software architecture, the design of a scalable model simplifying access to equipment and the construction of a display system able to handle the dataset for such a platform. The architecture developed in this work is designed to handle the constraints related to the hardware while assisting the integration of functional modules. This work was the subject of a chapter submitted for the book « Advances in Novel Microsystems Technologies and their Applications ». In addition to this, an efficient new mechanism for the rapid display of large amounts of data representing the system is proposed. This technical contribution is going to be published in CCECE 2013 conference (Canadian Conference on Electrical and Computer Engineering). Software resulting from this work is currently being used for demonstration and must serve as a validation tool for the hardware
