The event horizon as a vanishing point: A history of the first image of a black hole shadow from observation
… Telescope Collaboration (EHTC) released the first image of the shadow of a black hole based on observation. This is the closest astronomers have come to imaging a celestial object from which no light can escape. This dissertation offers an account of its formation and early reception based on …

VISUALIZATION OF CURRENT INDUCED SPIN ACCUMULATIONS IN THE STRONG SPIN-ORBITAL COUPLING MATERIALS
… spin-orbitronics phenomena. In this thesis, we first image the current induced spin accumulation at the channel edges of Bi2Se3 and BiSbTeSe2 topological insulators as well as Pt heavy metal by scanning photovoltage microscopy at room temperature. The spin polarization is along the out-of-plane …

Geometric and Kinematic Validation Studies in the Thoracic and Abdominal Regions of a Detailed Human-Body Finite Element Model
… Consortium (GHBMC) project is used in two ways. First, image data of various individuals is used to examine abdominal organ location, movement, and rib coverage as a result of posture. Secondly, the GHBMC mid-sized male (M50) model is used in a computational study focusing on a methodology for …

High performance lattice boltzmann method yield-stress calculations based on intravital images of clot formation in live mice
… dynamic simulation based on in vivo microscopic images of laser injury-induced thrombi and simulation provided critical yield stress information. To our knowledge, this is the first image-based in-vivo assessment of blood clots viscoelastic nature. Furthermore, the outcome of our work can assist …

Translational Modeling of Non-Invasive Electrical Stimulation
… were developed for clinical applications. The first image-derived models of obese subjects were developed to assess the relative impact of fat delineation from skin. Body mass index and more broadly inter-individual differences were considered. The effect of incorporating the meninges was …

Older than language : comics as philosophical praxis and heuristic for philosophical canon
… Mimicking the structure of comics wherein two images are juxtaposed to suggest (rather than explicitly state) a coherent sequence in the mind of the reader, this dissertation offers two "images" of its central thesis: one a theoretical element, the other a work of creative fiction. Following on …

IDeixis : image-based deixis for recognizing locations
… from camera-equipped mobile devices using image-based web search. This is an image-based deixis capable of pointing at a distant location away from the user's current location. We demonstrate our approach on an application allowing users to browse web pages matching the image of a nearby …

Reconstruction of extended environments from image sequences
… of a scene from a sequence of two-dimensional images has been the subject of considerable research in the field of machine vision, with applications as wide-ranging as object recognition, virtual reality and robot navigation. Traditional attempts to solve this structure from motion (SFM) …

Feature-based automatic registration of images with 2D and 3D models
Automatic image registration is the technique to align images in different coordinate systems to the same coordinate system which has found wide industrial applications for control automation and quality inspection. Focusing on the industrial applications where product models are available and …

The Sum-Product Theorem and its Applications
… computer vision, and deep learning. I first identify and prove the sum-product theorem, which states that in any semiring for inference to be tractable it suffices that the factors of every product have disjoint scopes; i.e., that they are decomposable. I show that this simple condition …

Contemporary Arts Museum in Roanoke: an Entrance to the City
… to its location the building will project the first image of the city. Therefore the proposed building should enhance and adapt to the social and cultural roots of the city. My thesis is a reaction to the existing conditions at the site for what I believe to be a lack of sensitivty to the …

The Effects of Curcumin On Body Composition of Patients With Advanced Pancreatic Cancer
… by 60±20 days. For treated patients, the first image was at the beginning of treatment and for controls it was determined by the matching time from advanced cancer. The evolution of body composition over time was quantitatively analyzed comparing both groups. All patients lost weight both …

Hormonal and genetic control of leaf and vein development in maize
… Through collaboration, I helped develop the first image analysis framework dedicated for the parallel venation in grasses which can quantify vein traits and detect vein patterning defects. In Chapter 2, I describe the first detailed spatial-temporal map of auxin, CK, and GA during early leaf …

Activity-dependent mitochondrial signaling drives GLR-1 dynamics and behavioral sensitization in C. elegans
… postsynaptic changes. In Chapter 2, we first image basal and activity-driven mitochondria calcium handling changes in C. elegans AVA interneurons. We then use a mcu-1(lf) mutant to investigate the effects of reduced mitochondrial calcium influx on tagged GLR-1 transport and recruitment …

Machine learning based digital image forensics and steganalysis
The security and trustworthiness of digital images have become crucial issues due to the simplicity of malicious processing. Therefore, the research on image steganalysis (determining if a given image has secret information hidden inside) and image forensics (determining the origin and authenticity …

Explaining Depravity through the Looking Glass: Political Prison Camps, North Korea, and Waltz's Three Images
<p>The political prison camps of North Korea are blatant violations of human rights within the state. They have recently received international attention within the United Nations General Assembly and the United Nations Security Council. This paper examines these political prison camps through …
