Rapid Climate Change In The Tropics: A Half-Million Year Long Geochemical Record From The Cariaco Basin, Venezuela, Kelly Ann Gibson

Open Access Dissertations

It is becoming increasingly apparent that rapid climate change on suborbital timescales is a persistent feature of Pleistocene climate. The rapid climate changes of the last glacial period – Dansgaard-Oeschger (D/O) cycles and Heinrich Events (HEs) – involved changes in sea and air temperature, atmospheric and oceanic circulation, and changes in hydrologic patterns that were nearly global in nature. Counterparts to D/O cycles and HEs have been found in marine sediment records of early glacial periods as far back as ~2.5 mya. Although the millennial-scale climate events of the last glacial period have been well studied, there is still much …

Bf2obn∙Oet2: A Novel Lewis Acid And Its Use In A Regio- And Stereo-Selective Opening Of Trisubstituted Epoxides And Its Application Towards Amphidinolide C, Nicholas A. Morra, Brian Pagenkopf

Chemistry Publications

The generation of a new Lewis acid (BF2OBn·OEt2) has been reported, and its usefulness has been demonstrated in the regio- and stereoselective ring-opening of trisubstituted epoxides. This Lewis acid is one in a series of new Lewis acids generated from BF3·OEt2 that display varying levels of Lewis acidity. When paired with a modified Shi epoxidation protocol, highly functionalized propionate units, such as those found in a wide variety of natural products, can be accessed. In conjunction with a Mukaiyama oxidative cyclization employing our second generation catalyst Co(nmp)2, this procedure ultimately culminated in the shortest and highest yielding route towards the …

A Centre-Stable Manifold For The Energy-Critical Wave Equation In R^3 In The Symmetric Setting, Marius Beceanu

Mathematics and Statistics Faculty Scholarship

Consider the focusing semilinear wave equation in R^3 with energy-critical nonlinearity \partial_t^2 \psi - \Delta \psi - \psi^5 = 0, \psi(0) = \psi_0, \partial_t \psi(0) = \psi_1. This equation admits stationary solutions of the form \phi(x, a) := (3a)^{1/4} (1+a|x|^2)^{-1/2}, called solitons, which solve the elliptic equation -\Delta \phi - \phi^5 = 0. Restricting ourselves to the space of symmetric solutions \psi for which \psi(x) = \psi(-x), we find a local centre-stable manifold, in a neighborhood of \phi(x, 1), for this wave equation in the weighted Sobolev space ^{-1} \dot H^1 \times< x>^{-1} L^2. Solutions with initial data on the …

Pin (Fibula), Risd Museum, Boris Bally, Jonathan Migliori

Channel

This fibula (pin), used for closing or securing garments, is a masterpiece of ancient gold-working. Tiny animals and figures, mythical and real, cover the pin. They were formed using tiny beads of gold (a process called granulation) fashioned in a fluid, curving style reminiscent of pottery of the seventh century BCE, when the Etruscans reached the height of their technical virtuosity in granulation. In the center of the decoration is a figure common in Etruscan art: the ‘master of the beasts,’ a winged man with two faces. The figure originated in the Near East and became especially prominent in Etruscan …

Increased Normal Incidence Photocurrent In Quantum Dot Infrared Photodetectors, Jiayi Shao, Thomas E. Vandervelde, Ajit Barve, Andreas Stintz, Sanjay Krishna

Birck and NCN Publications

We have increased the ratio of s-polarization (normal incidence) to p-polarization photocurrent to 50% in a quantum dot-in-a-well based infrared photodetector form the typical s-p polarization ratio about 20%. This improvement was achieved by engineering the dot geometry and the quantum confinement via post growth capping materials of the Stranski Krastanov growth mode quantum dots (QDs). The TEM images show that the height to base ratio of shape engineered QDs was increased to 8 nm/12 nm from the control sample's ratio 4 nm/17 nm. The dot geometry correlates with the polarized photocurrent measurements of the detector. (C) 2012 American Institute …

Using A Cognitive Architecture In Incremental Sentence Processing, Jeremiah Lane Mcghee

Theses and Dissertations

XNL-Soar is a specialized implementation of the Soar cognitive architecture. The version of XNL-Soar described in this thesis builds upon and extends prior research (Lewis, 1993; Rytting,2000) using Soar for natural language processing. This thesis describes the updates made to operators creating syntactic structure and the improved coverage of syntactic phenomena. It describes the addition of semantic structure building capability. This thesis also details the implementation of semantic memory and describes two experiments utilizing semantic memory in structural disambiguation. This thesis shows that XNL-Soar, as currently instantiated, resolves ambiguities common in language using strategies and resources including: reanalysis via snip …

Nonlinear Response Prediction Of Spar Platform Using Artificial Neural Network / Md. Alhaz Uddin, Uddin Md. Alhaz

Student Works (2010-2019)

Due to global energy demand, offshore industries are moving towards deep and ultra-deep waters for oil and gas exploration in ocean environment. Floating offshore structures such as spar platform is considered to be the most economic and suitable offshore structure in deep water regions. During oil and gas exploration, floating offshore structures may sometimes be affected by critical environmental forces. Quick decision must be taken either to continue or to stop production, on the basis of response prediction of offshore structures under forecasted environmental conditions. Finite Element Method (FEM) is an important technique to predict the response of offshore structures …

Quantum-Secured Imaging, Mehul Malik, Omar S. Magaña-Loaiza, Robert W. Boyd

Faculty Publications

We have built an imaging system that uses a photon's position or time-of-flight information to image an object, while using the photon's polarization for security. This ability allows us to obtain an image which is secure against an attack in which the object being imaged intercepts and resends the imaging photons with modified information. Popularly known as "jamming," this type of attack is commonly directed at active imaging systems such as radar. In order to jam our imaging system, the object must disturb the delicate quantum state of the imaging photons, thus introducing statistical errors that reveal its activity. © …

Identification Of Galactic Bulge Survey X-Ray Sources With Tycho-2 Stars, Robert I. Hynes, N. J. Wright, T. J. Maccarone, P. G. Jonker, S. Greiss, D. Steeghs, M. A.P. Torres, C. T. Britt, G. Nelemans

Faculty Publications

We identify 69 X-ray sources discovered by the Galactic Bulge Survey (GBS) that are coincident with or very close to bright stars in the Tycho-2 catalog. Additionally, two other GBS sources are resolved binary companions to Tycho-2 stars where both components are separately detected in X-rays. Most of these are likely to be real matches, but we identify nine objects with large and significant X-ray-to-optical offsets as either detections of resolved binary companions or chance alignments. We collate known spectral types for these objects, and also examine Two Micron All Sky Survey colors, variability information from the All-Sky Automated Survey, …

Cloud Computing For Environment-Friendly Data Centers, Michael Pawlish, Aparna Varde, Stefan Robila

Department of Computer Science Faculty Scholarship and Creative Works

The purpose of this paper is to analyze the carbon footprint and utilization rates in a data center. The long-term goal of this work is to give data center administrators an enhanced perspective of data center operations to allow for more energy efficient operation, to lower the carbon footprint, and to promote green data centers. Previous literature shows that low utilization rates in data centers are due to the forecasting of demand to meet spikes in data center use. This management policy has led to many servers running idle the majority of the time which is a waste of resources. …

Thin Films Of Carbon Nanotubes And Nanotube/Polymer Composites, Anthony D. Willey

Theses and Dissertations

A method is described for ultrasonically spraying thin films of carbon nanotubes that have been suspended in organic solvents. Nanotubes were sonicated in N-Methyl-2-pyrrolidone or N-Cyclohexyl-2-pyrrolidone and then sprayed onto a heated substrate using an ultrasonic spray nozzle. The solvent quickly evaporated, leaving a thin film of randomly oriented nanotubes. Film thickness was controlled by the spray time and ranged between 200-500 nm, with RMS roughness of about 40 nm. Also described is a method for creating thin (300 nm) conductive freestanding nanotube/polymer composite films by infiltrating sprayed nanotube films with polyimide.
