Improving reconstructions of digital holograms
… into two distinct parts: A) speckle reduction in reconstructions of digital holograms (DHs), and B) modeling and overcoming partial occlusion e®ects in reconstructions of DHs, and using occlusions to reduce the effects of the twin image in reconstructions of DHs. Part A represents the major part …

Cheminformatics for genome-scale metabolic reconstructions
Genome-scale metabolic reconstructions are an important resource in the study of metabolism. They provide both a system and component level view of the biochemical transformations of metabolites. As more reconstructions have been created it remains a challenge to integrate and reason about their …

Aerial reconstructions via probabilistic data fusion
… of a given scene. In urban environments, these reconstructions have many applications, such as surveillance, and urban planning. The proposed probabilistic model can be viewed as a data fusion model, in which the two data sources complement each other and allow for better results than when only …

Pertes et Reconstructions Identitaires des Foyers Post-Divorce
La présente étude s’intéresse au parcours des foyers post-divorce via deux objectifs. Premièrement, nous voulons mettre en avant les éléments organisateurs permettant à ces foyers de passer d’un état à un autre. Pour ce faire, nous recourons à la méthode par théorisation ancrée, bien qu’en nous en …

Tufa-based reconstructions of Huasco Basin Lake levels
… as a potential site for palaeohydrological reconstructions of precipitation over the South American Altiplano, and presents a preliminary lake level chronology for the last deglaciation. Resolving the timings of past lake level highstands in the South American Altiplano will ultimately …

Digital reconstructions of fossil morphologies, Nama Group, Nambia
Previously undescribed fossils of weakly calcified metazoans were recently discovered in the terminal Proterozoic Nama Group of central and southern Namibia (Grotzinger et al., 1995), in sediments that contain the terminal Proterozoic index fossil Cloudina. The new fossils are closely associated …

Visually Accurate Database-Enabled Reconstructions of Scenes (VADERS)
… analysis, segmentation, and retexturing to yield reconstructions that preserve structural semantics, while convincingly reflecting the visual qualities of the original image. The motivation lies in the limitations of existing systems. Existing databaseassisted approaches depend on proprietary …

Autonomous Sample Collection Using Image-Based 3D Reconstructions
… 3D point clouds produced via image-based 3D reconstructions. A custom robotic mobility platform, the Scoopbot, is introduced to perform completely automated imaging of the sampling area and also to pick up the desired sample. The Scoopbot is wirelessly controlled by a base station computer …

Reconstructions: Nine Movements for Solo Soprano, Chorus, and Wind Ensemble
Reconstructions is a nine-movement composition for solo soprano, chorus, and wind ensemble using texts from several of Emily Dickinson's poems. The soloist represents the main character in this dramatic work, and the narrative structure portrays abstract moments in this character's life. While the …

Phase-space reconstructions of cosmic velocities and the cosmic web
… matter. In this thesis I present cosmological reconstructions of both, the dark matter density field that forms the cosmic web, and cosmic velocities, for which both aspects of my work are delved into, the theoretical formalism and the results of its applications to cosmological simulations and …

Development of biomarker-based proxies for paleo sea-ice reconstructions
… extent, together with more quantitative sea-ice reconstructions. In the Southern Ocean, the distributions of di- and tri-unsaturated HBIs (HBI diene II and HBI trienes IIIa and IIIb) in surface waters were shown to be extremely sensitive to the local sea-ice conditions, consistent with …

Algorithmic Computer Reconstructions of Stalactite Vaults - Muqarnas - in Islamic Architecture
… We can construct three--dimensional computer reconstructions directly from the directed subgraphs. An algorithm is developed for constructing the directed subgraphs and reconstructing the three--dimensional muqarnas. Two software tools are designed to execute this process. The program …

Memorial Reconstructions: Christopher Marlowe, Cultural Memory, and the Royal Shakespeare Company
"Chapter One traces the creation of the Marlowe myth through the critical record and identifies four persistent aspects of that myth: when compared to Shakespeare, Marlowe is repeatedly figured as an atheist, bohemian, ""queer,"" and foreign figure. Chapter Two explores the permanent, physical …

Image-based 3D Reconstructions via Differentiable Rendering of Neural Implicit Representations
… application scenarios. For instance, current reconstructions typically assume the scene to be perfectly opaque with no semi-transparent effects, or assume no dynamic noise or occluders are included in the capture, or do not optimize rendering efficiency for high-frequency appearance in the …

Verification of rain-flow reconstructions of a variable amplitude load history
The suitability of using rain-flow reconstructions as an alternative to an original loading spectrum for component fatigue life testing is investigated. A modified helicopter maneuver history is used for the rain-flow cycle counting and history regenerations. Experimental testing on a notched test …

Centennial-scale reconstructions of mountain glacier fluctuations during the Holocene, West Greenland
… driving present-day glacier change, geological reconstructions of former glacier fluctuations provide additional data on glacier behavior over longer timescales, and place much-needed constraints on the sensitivity of glacier response to climate change. Here, I employ a novel multi-proxy …

Modelling Sea-Level Reconstructions from Southern Greenland: Implications for Glacially-Induced Faulting
Understanding the past evolution of the Greenland ice sheet (GrIS) is important for accurately simulating its future behavior and thus its contribution to global mean sea level rise. Data and models related to glacial isostatic adjustment (GIA) have provided critical constraints on past GrIS …

Antarctic Station-based Pressure Reconstructions from 1905-2011 using Principal Component Regression
… spring are slightly weaker. Nevertheless, the reconstructions of all seasons are still better than using the climatological mean alone, and as such, all reconstructions are deemed to have some scientific use.</p><p>Since the reconstructions extend nearly double the observed record at each …
