Scenery reconstruction
… walk sees the color where it is on. Scenery Reconstruction problem can be described by the next question: Can the original coloring be reconstructed given only one realization of the observations? This thesis presents three new results about Scenery Reconstruction. The first of them shows how …

Transaction reconstruction
… transactions interrupted by failures. Reconstruction duplicates only those components of active transactions that are actually lost when failures occur, offering superior efficiency while retaining a level of resiliency comparable to that achieved by replication.

Revisiting prosodic reconstruction
… develop a theoretical implementation of prosodic reconstruction and apply it to the empirical domain of German sentences in which part of a focus or contrastive topic is fronted. Prosodic reconstruction refers to the idea that sentences involving syntactic movement show prosodic parallels with …

Constrained signal reconstruction
… reported in this dissertation addresses the reconstruction of signals and images from linear measurements subject to convex constraints. The objectives are to describe the existence and uniqueness of solutions, to characterize reconstructions, and to develop algorithms for efficiently …

Online neuron reconstruction
In this thesis, I designed an algorithm that traces neurons through the images of various datasets extracted from mouse brains. The algorithm is implemented in Python and relies on the output of a recently developed Fully Convolutional Neural Network (implemented in C) that runs on the underlying …

Trace reconstruction problem
In the setting of the trace reconstruction problem, a uniform random binary sequence w [epsilon] {0, 1}n yields a collection of traces, such that each subsequence is obtained by independently deleting each bit with a public probability parameter p. In this thesis we explore a restricted version of …

3D tooth surface reconstruction
… of a point distribution model (PDM). During the reconstruction process, an automatic rigid registration (possibly preceded by a manual one) is realized to align the model with the target, and the PDMa??s parameters are optimized to transform the target by minimizing the sum of squared distances …

Reconstruction from image correspondences
… contained in every single image. Visual reconstruction methods confront with the formidable, and still unanswered, challenge of delivering a comprehensive representation of structure, motion and appearance of a scene from visual information. Multi-view visual reconstruction deals with the …

Helical Reconstruction in RELION
… tuning many ad hoc parameters to achieve optimal reconstruction results. REgularised LIkelihood OptimisatioN (RELION), an open-source single-particle analysis package, reduces the need for user expertise by the formulation of an empirical Bayesian framework, and has yielded some of the highest …

Contracting for disaster reconstruction
… to complete the multitude of assessments, reconstruction projects, and rebuilding missions in the wake of large-scale storms. International governments have faced similar challenges, and through case studies and informant interviews, an evaluation of contractual structures that affect …

Reconstruction algorithms for MRI
This dissertation presents image reconstruction algorithms for Magnetic Resonance Imaging (MRI) that aims to increase the imaging efficiency. Algorithms that reduce imaging time without sacrificing the image quality and mitigate image artifacts are proposed. The goal of increasing the MR efficiency …

Reconstruction Delayed: How Presidents and the Southern Civil War Prolonged the End of Reconstruction
Reconstruction is one of the most controversial periods in American history. The decade which followed the conclusion of the American Civil War featured debates in the North and extreme violence in the South. The major argument was over what the next steps would be in terms of reuniting the nation …

Fluid surface reconstruction from particles
Outlined is a new approach to the problem of surfacing particle-based fluid simulations. The key idea is to construct a surface that is as smooth as possible while remaining faithful to the particle locations. We describe a mesh-based algorithm that expresses the surface in terms of a constrained …

Shape Reconstruction with Topological Priors
… role in solving the inverse problem of shape reconstruction. We classify the applications into 1D, 2D, and 3D cases:</p><p>In 1D, we show that the persistent extrema of the curvature function of a closed curve are useful for shape simplication. In 2D, we study how to label a scene into …

Numerical Analysis of Flux Reconstruction
… One such high-order method in particular – Flux Reconstruction – is the focus of this thesis. This body of work relies and expands on the theoretical methods that are used to understand the behaviour of numerical methods – particularly related to their real-world application to industrial …
