Three-Dimensional Particle Image Velocimetry Using a Plenoptic Camera
No full textA novel 3-D, 3-C PIV technique is described, based on volume illumination and a plenoptic camera to measure a velocity field. The technique is based on plenoptic photography, which uses a dense microlens array mounted near a camera sensor to sample the spatial and angular distribution of light entering the camera. Various algorithms are then used to reconstruct a volumetric intensity field after the image is taken, and cross-correlation algorithms extract the velocity field from the reconstructed volume. This paper provides an introduction to the concepts of light fields and plenoptic photography, and describes the algorithms used to reconstruct the measurement volume. A comparison is made between the use of a combined computational refocusing and thresholding approach versus a direct tomographic reconstruction approach. This discussion lays the groundwork for a more detailed study of reconstruction accuracy, achieveable particle number density, reconstruction ambiguities (e.g., ghost particles), and other factors in a following study. Additionally, the construction of a prototype camera based on a 16-megapixel interline CCD sensor is described and preliminary experimental renderings are given.Aerodynamics, Wind Energy & PropulsionAerospace Engineerin
Recent Development of Volumetric PIV with a Plenoptic Camera
No full textThe recent development of a volumetric PIV system utilizing the unique light-field capturing capabilities of a plenoptic camera is described. The fundamental concept of a plenoptic camera, including a distinction between plenoptic 1.0 and plenoptic 2.0 is given, along with an illustration of the ability to computationally refocus an image after it has been acquired. A synthetic image generator for plenoptic cameras was developed and used to simulate plenoptic imaging of the motion of 3D particle fields. For volumetric reconstruction, the MART algorithm was adapted for use with the plenoptic camera through a reformulation of the weighting matrix that is consistent with the optical properties of the plenoptic camera. A prototype camera was designed and constructed based on the modification of a 16 MP PIV camera such that a microlens array can be mounted near the image sensor. This camera was used to show the proof-of-concept of the camera\u92s ability to measure a 3D velocity field through experiments performed in a subsonic turbulent boundary layer and a supersonic jet. In both cases, the feasibility of plenoptic PIV was demonstrated with noted strengths being the simple set-up and operation of the system in addition to the ability to make 3D measurements over relatively large volume
Humanizing intellectual capital reporting : a case study on implementing a reporting system at the University of Innsbruck
No full textÖsterreich war das erste Land weltweit, das die Erstellung von Wissensbilanzen Intellectual Capital Reports) gesetzlich vorschrieb (§ 13 Universitätsgesetz 2002). Die vorliegende Arbeit befasst sich mit der wissenschaftlichen Aufarbeitung der Einführung und laufenden Erstellung der Wissensbilanzen an der Universität Innsbruck für die Jahre 2005 - 2012. Ausgangspunkt der Dissertation ist die Forschungsfrage, wie eine österreichische Universität ein ethisch und ökonomisch verantwortungsvolles Berichtswesen auf Basis der Wissensbilanz aufbauen kann.
Ethik und Ökonomie finden eine gemeinsame Basis in der Rechenschaftspflicht, deren Notwendigkeit von politischer Seite auf der ideologischen Basis von "New Public Management" mit dem ethischen Anspruch der SteuerzahlerInnen auf die sorgsame Verwendung ihrer Steuermittel begründet wird. Die Dissertation hinterfragt auf Basis einer Fallstudie an der Universität Innsbruck, inwieweit Wissensbilanzen diese Ansprüche für österreichische Universitäten erfüllen können und inwieweit dabei die politischen und gesellschaftlichen Rahmenbedingungen, in die Wissensbilanzen eingebettet sind, eine Rolle spielen.
Als qualitativer Forschungsansatz für die vorliegende Arbeit wurde Aktionsforschung gewählt. Als Methoden wurden Interviews, Dokumentenanalyse und beobachtende Teilnahme eingesetzt. Der wissenschaftliche Beitrag der vorliegenden Arbeit knüpft daran an, dass Wissensbilanzen auf ihre ethischen Grundlagen und Implikationen hin wenig erforscht sind. Darüber hinaus gibt es in der scientific community den Bedarf nach weiterer Erforschung der österreichischen Erfahrungen mit der Erstellung von Wissensbilanzen. Schließlich legt die Arbeit neues Material vor, das als Grundlage für weitere Studien verwendet werden kann. Es handelt sich dabei um Daten und Informationen sowie Erfahrungen aus der Perspektive der Autorin, die im Zeitraum 2005 - 2012 für die Einführung und Erstellung von Wissensbilanzen an der Universität Innsbruck verantwortlich war.Austria was the first country worldwide to implement Intellectual Capital Reports (ICRs) based on a Legal Act, the University Law 2002 (§ 13). This dissertation is a scientific reflection of the implementation and production of ICRs for the years 2005 - 2012. It is based on the research question,how an Austrian university should be able to implement and develop university reporting based on Intellectual Capital Reports, considering its ethical and economic accountability.
Ethics and Economics have a common basis in accountability, which is argued by politicians grounded in the ideology of New Public Management (NPM) with the ethical right of tax payers that their taxes are used efficiently. This dissertation questions, based on a case study at the University of Innsbruck, how ICRs can fulfill this need for accountability for Austrian universities and the role of the political and societal framework that ICRs are embedded in.
The qualitative research approach, taken for this dissertation, is Action Research. Interviews, Document analyses and "observant participation" serve as methods. The scientific contribution of this dissertation is based on the need for more research as far as the ethical implications and background of ICRs are concerned. In addition, there is a need for further research for the Austrian experience with the production of ICRs. Finally, the author presents new data and information as well as experiences from the perspective of the author, who was responsible for the implementation and production of ICRs at the University of Innsbruck from 2005 - 2012.by Christine FahringerDissertation Universität Innsbruck 201

Opening The (Artists') Books: Enhancing Discovery Through Student Research
No full textLocation: Dewberry Hall
Over the past few years, Mason Libraries has collected a critical mass of artists' books, which are complex artistic expressions that incorporate a range of techniques, styles, materials, and subjects. Our project will address new modes of discovery and access for this collection. Artists’ books–an artistic expression that uses the book as a medium–are collected by the University Libraries and used in research and classes from multiple disciplines. With over 350 items in this growing collection, representing a broad variety of disciplines, media, and modes of production, it is imperative to have multiple points of access in order for students, faculty, librarians, and other researchers to identify and more easily locate and use these unique objects. More specifically, we need to develop a way to facilitate searching for items based on their features such as bindings, paper types, and printing technologies in addition to their topic(s)and more traditional “author/date/title” searches. A team of librarians, archivists, and digital scholarship specialists is developing a long-term plan for the Libraries to collaborate with undergraduate and graduate student teams and subject faculty to first analyze and describe the books, and then create an online resource that incorporates their descriptions with a robust search functionality to provide a scholarly resource for students, faculty, and researchers. The project is multi-faceted, will last more than 24 months, and includes at least two cohorts of students. These students will have the opportunity to apply their learned artistic knowledge to more fulsomely describe the Libraries’ artists’ books, as well as develop leadership and project management skills. By analyzing artists’ books within established best practices and recognized standards, students will be able to transfer these experiences to both their own future coursework and research, as well as their creative and professional careers. A second phase of the project will involve developing these descriptions into a digital format. Students will work with the project team to assess existing digital platforms in relation to project needs and then implement the metadata schema to the selected digital resource. Ultimately, this resource will enhance the discoverability of the artists’ book collection, and students, faculty, and researchers will be able to perform faceted searches to view detailed descriptions and browse high-quality images of each book. In this presentation, the librarians and archivists will discuss the project stages, outlining the artistic and technology goals and needs of the students, and partnership opportunities with faculty and classes during the project and after its completion
