Singularity Deferred
Singularity Deferred is a work of original fiction. It is a science fiction novel that features Mitchel Creek, a man with a young family, who finds himself mysteriously transported onto a spacecraft centuries into the future—alone save for a strange device and a dead body. As he discovers how he …

Algorithms for Bivariate Singularity Analysis
An algorithm for bivariate singularity analysis is developed. For a wide class of bivariate, rational functions F = P/Q, this algorithm produces rigorous numerics for the asymptotic analysis of the Taylor coefficients of F at the origin. The paper begins with a self-contained treatment of …

Approaching the Singularity in Gowdy Universes
… symmetric dust can collapse to form a naked singularity. Since Gowdy universes comprise gravitational waves that are locally cylindrically symmetric, perhaps these waves can collapse onto a symmetry axis and create a naked singularity. It is known that in the case of cylindrical symmetry, …

Pseudoholomorphic quilts with figure eight singularity
… is pseudoholomorphic quilts with figure eight singularity. In the first part, I propose a blueprint for constructing an algebraic object that binds together the Fukaya categories of many different symplectic manifolds. I call this object the "symplectic A[infinity]-2-category Symp". The key to …

The Derived Category and the Singularity Category
… of a variety and the equivari- ant/graded singularity category of a corresponding singular variety. The equivalence also holds at the dg level.

Condition of Singularity: Viewer, Temporality and Otherness
Differences are an inescapable factor in the event of presentation. Rifts manifest themselves one after another between the object of presentation, the appearance of the presentation, the method of presentation, what/who presents it and to what/whom it is presented and so on. In fact it is a course …

Judaizing and Singularity in England, 1618-1667
In the seventeenth century, in England, a remarkable number of small, religious movements began adopting demonstratively Jewish ritual practices. They were labelled by their contemporaries as Judaizers. Typically, this phenomenon has been explained with reference to other tropes of Puritan …

Local complex singularity exponents for isolated singularities
… thesis, I studied the stability of local complex'singularity exponents (lcse) for holomorphic functions whose zero sets have only isolated singularities. For a given holomorphic function f defined on a neighborhood of the origin in C[to the power of]n, the lcse c[sub]0(f) is defined as the …

Two cylindrical vortex sheets : evolution and singularity formation
… fitted to gain insight into aspects of the singularity formation; these include the order of the branch-point singularities, and the times and locations of singularity formation. A smoothing over initial singularity formations is implemented by either the heat equation or through a local …

Random surfaces and the Yang-Lee edge singularity
… on a random planar graph. The Yang-Lee edge singularity, familiar from the ordinary Ising model, is exposed. It is shown to correspond to an exactly solvable critical dimer counting problem on the random surface in the infinite temperature limit. The results lead to a deepened insight into …

Time-domain developments in the singularity expansion method
This research presents two switching techniques using SOT and SLACK, as complementary sequencing rules, to show that they are practical procedures to control a job shop. These two approaches are: - Static switching of the complementary rules. - Dynamic switching of the complementary rules. This …

Analysis of an Embedded Singularity Chipless RFID Tag
The objective of this research is to explore the feasibility of a chipless RFID tag that stores a data signature in the form of complex frequency plane singularities. To this end an existing chipless RFID tag, the notched elliptical dipole tag, was analyzed first with simulations and then …

Ultra-Wideband Channel Modeling using Singularity Expansion Method
… is to model resonant dispersion based on the Singularity Expansion Method (SEM) and provide guidelines for UWB receiver design to meet the data capacity. The original contribution of this research is a novel pole dispersion channel model that includes resonant dispersion characterization. An …

Domain decomposition for hexahedral mesh generation using singularity lines
… where other than four blocks join (called singularity lines) are of high importance. This has motivated many researchers to develop methods that first identify these lines and then, based on them, generate the decomposition of the domain. However, even for simple models these methods often …

The Singularity of Witness : Memory, Poetry and the Refugee.
This thesis addresses the question of bearing witness. It hypothesizes that witnessing is singular in nature and as such, demands certain kinds of idioms. It problematizes modern politico-scientific conceptions of knowledge for their insistence on functionality, universalization and calculability. …

Infinite derivative gravity : a ghost and singularity-free theory
The objective of this thesis is to present a viable extension of general relativity free from cosmological singularities. A viable cosmology, in this sense, is one that is free from ghosts, tachyons or exotic matter, while staying true to the theoretical foundations of General Relativity such as …

Even Parity Perturbations of the Janis-Newman-Winicour Singularity
… perturbations to the Janis-Newman-Winicour singularity by extending the analysis to even-parity perturbations. Perturbations to the metric can be decomposed using tensor spherical harmonics and Fourier decomposition, and are further reduced by gauge transformations. By calculating the …

On long time dynamic and singularity formation of NLS
… Schrödinger equation (NLS). We will focus on the singularity formation and long time asymptotics. To be specific, there are two parts in the thesis. In the first part, we give a construction of log-log blow up solutions which blow up at m prescribed points simultaneously. In the second part, we …

The Myth of Techno-Transcendence: The Rhetoric of the Singularity
… emergence of these types of discourses is the Singularity, a story about a future point where human and machine intelligence is indistinguishable and humanity has been transformed by technology. As such, in this study, I illuminate and analyze the rhetorical form and function of both pro- and …

Topological analysis of singularity loci for serial and parallel manipulators
… therefore it might be desirable to search for singularityfree trajectories in the jointspace. On the other hand, parallel singularities are very dangerous for parallel manipulators, for they may provoke the local loss of platform control, and jeopardize the structural integrity of links or …
