We have completed a new optical imaging and spectrophotometric survey of a 140 × 80 pc2 region of 30 Doradus centered on R136, covering key optical diagnostic emission lines including Hα, Hβ, Hγ, [O III] λλ4363, 4959, 5007, [N II] λλ6548, 6584, [SII] λλ6717, 6731 [S III] λ6312, and in some locations [S III] λ9069. We present maps of fluxes and intensity ratios for these lines, and catalogs of isolated ionizing stars, elephant-trunk pillars, and edge-on ionization fronts. The final science-quality spectroscopic data products are available to the public. Our analysis of the new data finds that, while stellar …


An Analytical Model Of A Thermally Excited Microcantilever Vibrating Laterally In A Viscous Fluid, Stephen M. Heinrich, Rabin Maharjan, Isabelle Dufour, Fabien Josse, Luke A. Beardslee, Oliver Brand Nov 2010

An Analytical Model Of A Thermally Excited Microcantilever Vibrating Laterally In A Viscous Fluid, Stephen M. Heinrich, Rabin Maharjan, Isabelle Dufour, Fabien Josse, Luke A. Beardslee, Oliver Brand

Civil and Environmental Engineering Faculty Research and Publications

To achieve higher quality factors (Q) for microcantilevers used in liquid-phase sensing applications, recent studies have explored the use of the lateral (in-plane) flexural mode. In particular, we have recently shown that this mode may be excited electrothermally using integrated heating resistors near the micro cantilever support, and that the resulting increase in Q helps to make low-ppb limits of detection a possibility in liquids. However, because the use of electrothermally excited, liquid-phase, microcantilever-based sensors in lateral flexure is relatively new, theoretical models are lacking. Therefore, we present here a new analytical model for predicting the vibratory response of these …

Search For Gravitational Waves From Compact Binary Coalescence In Ligo And Virgo Data From S5 And Vsr1, J. Abadie, Marco Cavaglia, For Full List Of Authors, See Publisher's Website.

Physics Faculty Research & Creative Works

We report the results of the first search for gravitational waves from compact binary coalescence using data from the Laser Interferometer Gravitational-Wave Observatory and Virgo detectors. Five months of data were collected during the Laser Interferometer Gravitational-Wave Observatory's S5 and Virgo's VSR1 science runs. The search focused on signals from binary mergers with a total mass between 2 and 35M⊙. No gravitational waves are identified. The cumulative 90%-confidence upper limits on the rate of compact binary coalescence are calculated for nonspinning binary neutron stars, black hole-neutron star systems, and binary black holes to be 8.7 x 10- …

A New Carnosaur (Dinosauria: Theropoda) From The Upper Morrison Formation (Late Jurassic, Tithonian) Of Colorado, Sebastian Dalman Nov 2010

A New Carnosaur (Dinosauria: Theropoda) From The Upper Morrison Formation (Late Jurassic, Tithonian) Of Colorado, Sebastian Dalman

Master's Theses or Doctor of Nursing Practice

A disarticulated skeleton of a theropod from the Late Jurassic (Tithonian) strata of McElmo Canyon in Montezuma County, Colorado was discovered in 1953 by the late J. T. Gregory and D. Techter. For nearly 55 years the specimen remained unnoticed in the collection of the Yale Peabody Museum of Natural History in New Haven, Connecticut. Several cranial and postcranial elements are relatively well preserved and include the premaxilla, maxilla, dentary, teeth, quadratojugal, braincase, metacarpals, partial pubis and ischium, astragalus, partial tibia and fibula, metatarsals, pedal phalanges, and several partially preserved ribs. The specimen represents a new genus and species of …


Milliamperage-Seconds, Kilovoltage And Patient Dose In Computed Radiography, Grace Stewart Nov 2010

Milliamperage-Seconds, Kilovoltage And Patient Dose In Computed Radiography, Grace Stewart

Master's Theses or Doctor of Nursing Practice

Radiographic techniques were applied to a human simulation pelvis phantom with evaluations of the resultant image analyzed by a designated radiologist. Results indicate that a lower patient dose is received when coupled with an increase in the tube voltage. Images analyzed demonstrated little noise variation between images, which indicates the ability to lower patient dose while maintaining quality images.

Multi-Scale Perspectives On Paddlefish Populations: Implications For Species Conservation And Management, Brenda M. Pracheil Nov 2010

Multi-Scale Perspectives On Paddlefish Populations: Implications For Species Conservation And Management, Brenda M. Pracheil

School of Natural Resources: Dissertations, Theses, and Student Research

The Order of fishes containing paddlefish and sturgeon has been named the most endangered group of organisms on the planet by the International Union of Conservation of Nature (IUCN). Population trajectories of paddlefish, whose native range is entirely encompassed within the United States of America, are currently unknown, although the IUCN has considered them to have a high extinction risk in the wild. The declaration of the vulnerability of paddlefish to extinction, coupled with the global plight of other sturgeon species create urgency to establish population and species-level population trajectories. Moreover, this declaration creates a great need for swift management …


Spatial Similarities And Differences Of Attributes Of Three Subwatersheds Within The Middle Smoky Hill River Watershed And Their Relationship To Instream Total Suspended Solids, Dustin Fross Nov 2010

Spatial Similarities And Differences Of Attributes Of Three Subwatersheds Within The Middle Smoky Hill River Watershed And Their Relationship To Instream Total Suspended Solids, Dustin Fross

Master's Theses or Doctor of Nursing Practice

The objective of this study was to spatially analyze the attributes of three subwatersheds, Hydrological Unit Code 12 (HUC 12), of the Middle Smoky Hill River Watershed in west-central Kansas and relate the variances of the attributes to the concentrations of total suspended solids (TSS) entering the Smoky Hill River during storm events. This was accomplished by comparing land cover, including cropland, grassland, and urban factors; agricultural practices, such as tillage methods, condition of terraces, and the presence of grass waterways; geomorphology, including soil types, topography, and visible erosion; and lastly, precipitation variance. The three HUC 12s that were studied …

Fuzzy Logic Control Of An Inverted Pendulum Robot, Kyle Reid Nov 2010

Fuzzy Logic Control Of An Inverted Pendulum Robot, Kyle Reid

Electrical Engineering

The inverted pendulum is a classical problem in controls.  The inherit instabilities in the setup make it a natural target for a control system.  Over the years it has been the benchmark for testing new and innovative control theories such as Fuzzy Logic.  During the course of this project a software fuzzy logic controller was implemented using a PIC microcontroller.  At the conclusion of the experiment an interesting realization was made about the nature of Fuzzy Logic and its applicability in the world of controls.

Some Communication Complexity Results And Their Applications, Joshua E. Brody Nov 2010

Some Communication Complexity Results And Their Applications, Joshua E. Brody

Dartmouth College Ph.D Dissertations

Communication Complexity represents one of the premier techniques for proving lower bounds in theoretical computer science. Lower bounds on communication problems can be leveraged to prove lower bounds in several different areas. In this work, we study three different communication complexity problems. The lower bounds for these problems have applications in circuit complexity, wireless sensor networks, and streaming algorithms. First, we study the multiparty pointer jumping problem. We present the first nontrivial upper bound for this problem. We also provide a suite of strong lower bounds under several restricted classes of protocols. Next, we initiate the study of several non-monotone …


Hexakis(Prop-2-Enamide)Copper(Ii) Bis(Perchlorate) And Hexakis(Prop-2- Enamide)Manganese(Ii) Bis(Perchlorate), Mary Mcnamara, Andrew Kellett, Georgina Rosair, Michael Devereux, Malachy Mccann Nov 2010

Hexakis(Prop-2-Enamide)Copper(Ii) Bis(Perchlorate) And Hexakis(Prop-2- Enamide)Manganese(Ii) Bis(Perchlorate), Mary Mcnamara, Andrew Kellett, Georgina Rosair, Michael Devereux, Malachy Mccann

Articles

The structures of [Cu(AA)6](ClO4)2, (I), and [Mn(AA)6](ClO4)2, (II) (AA is acrylamide, also known as prop-2-enamide; C3H5NO), display both intra- and intermolecular N-H...O hydrogen bonding. A three-dimensional network is propagated via the perchlorate counter-ions. There are two crystallographically independent molecules in the copper complex, with the most significant difference between them being the conformation of one symmetry-related pair of AA ligands which are in the unusual syn conformation. The copper complex exhibits syn/anti disorder of the =CH2 group in one pair of symmetry-related AA ligands. The CuII and MnII centres are both situated on centres of inversion. The copper complex cation …

Current Status And Long-Term Trends In Water Quality And Living Resources In The Virginia Tributaries And Chesapeake Bay Mainstem From 1985 Through 2009, Daniel M. Dauer, Harold G. Marshall, John R. Donat, Michael F. Lane, Suzanne C. Doughten, Frederick A. Hoffman, Raghavendra Kurada

Status and Trends for Virginia Chesapeake Bay

The period prior to the implementation of the Chesapeake Bay Monitoring Program was characterized by a marked decline in the water quality of the Chesapeake Bay. The disappearance of submerged aquatic vegetation in certain regions of the Bay, declines in the abundance of some commercially and recreationally important species, increases in the incidence of low dissolved oxygen events, changes in the Bay's food web, and other ecological problems have been related to the deteriorating water quality (e.g. USEPA, 1982,1983;Officer et al.,1984; Orth and Moore, 1984). The results of concentrated research efforts in the late 1970s and early 1980s stimulated the …

Pulsed Laser Deposition Of Graphite Counter Electrodes For Dye-Sensitized Solar Cells, Krishna P. Acharya, Himal Khatri, Sylvain Marsillac, Bruno Ullrich, Pavel Anzenbacher, Mikhail Zamkov Nov 2010

Pulsed Laser Deposition Of Graphite Counter Electrodes For Dye-Sensitized Solar Cells, Krishna P. Acharya, Himal Khatri, Sylvain Marsillac, Bruno Ullrich, Pavel Anzenbacher, Mikhail Zamkov

Electrical & Computer Engineering Faculty Publications

We report on pulsed laser deposition of graphite onto flexible plastic and conductive glass substrates for use as a counter electrode in dye-sensitized solar cells. The efficiency of as-prepared graphite electrodes was tested using CdS-sensitized solar cell architecture resulting in external quantum efficiency comparable to that of conventional platinum counter electrodes. This work highlights the possibility of using pulsed laser deposited graphite as a low-cost alternative to platinum, which could be fabricated both on flexible and rigid substrates.

Isotherms And Kinetics Studies Of Lead Adsorption On Jatropha Seed Husk., Faheem Ahmed Qaid Mohammed Nov 2010

Isotherms And Kinetics Studies Of Lead Adsorption On Jatropha Seed Husk., Faheem Ahmed Qaid Mohammed

Student Works (2010-2019)

Presence of lead, a heavy metal in the environment has been a serious concern especially with rapid industrialization which has created new uses for lead. The acute toxicity of lead to aquatic Life and humans and the stringent effluent standard to be met by industries as specified by regulatory organizations has necessitated the development of innovative, effective and economical methods for treating lead-bearing wastewater. An adsorption process using an inexpensive adsorbent such as Jatropha seed husk is an attractive option for the removal of lead from wastewater. In this study batch isotherm and kinetic studies were carried out on a …

Powerpack: Energy Profiling And Analysis Of High-Performance Systems And Applications, Rong Ge, Xizhou Feng, Shuaiwen Song, Hung-Ching Chang, Dong Li, Kirk W. Cameron Nov 2010

Powerpack: Energy Profiling And Analysis Of High-Performance Systems And Applications, Rong Ge, Xizhou Feng, Shuaiwen Song, Hung-Ching Chang, Dong Li, Kirk W. Cameron

Mathematics, Statistics and Computer Science Faculty Research and Publications

Energy efficiency is a major concern in modern high-performance computing system design. In the past few years, there has been mounting evidence that power usage limits system scale and computing density, and thus, ultimately system performance. However, despite the impact of power and energy on the computer systems community, few studies provide insight to where and how power is consumed on high-performance systems and applications. In previous work, we designed a framework called PowerPack that was the first tool to isolate the power consumption of devices including disks, memory, NICs, and processors in a high-performance cluster and correlate these measurements …


On Semigroups With Lower Semimodular Lattice Of Subsemigroups, Peter R. Jones Nov 2010

On Semigroups With Lower Semimodular Lattice Of Subsemigroups, Peter R. Jones

Mathematics, Statistics and Computer Science Faculty Research and Publications

The question of which semigroups have lower semimodular lattice of subsemigroups has been open since the early 1960s, when the corresponding question was answered for modularity and for upper semimodularity. We provide a characterization of such semigroups in the language of principal factors. Since it is easily seen (and has long been known) that semigroups for which Green's relation J is trivial have this property, a description in such terms is natural. In the case of periodic semigroups—a case that turns out to include all eventually regular semigroups—the characterization becomes quite explicit and yields interesting consequences. In the general case, …

How To Write A Good Paper In Computer Science And How Will It Be Measured By Isi Web Of Knowledge, Rǎzvan Andonie, Ioan Dzitac

All Faculty Scholarship for the College of the Sciences

The academic world has come to place enormous weight on bibliometric measures to assess the value of scientific publications. Our paper has two major goals. First, we discuss the limits of numerical assessment tools as applied to computer science publications. Second, we give guidelines on how to write a good paper, where to submit the manuscript, and how to deal with the reviewing process. We report our experience as editors of International Journal of Computers Communications & Control (IJCCC). We analyze two important aspects of publishing: plagiarism and peer reviewing. As an example, we discuss the promotion assessment criteria used …
