Measuring The Water Level Datum Relative To The Ellipsoid During Hydrographic Survey, Glen Rice, Jack Riley

Center for Coastal and Ocean Mapping

Hydrographic surveys are referenced vertically to a local water level “chart” datum. Conducting a survey relative to the ellipsoid dictates a datum transformation take place before the survey is used for current navigational products. Models that combine estimates for the tide, sea surface topography, the geoid, and the ellipsoid are often used to transform an ellipsoid referenced survey to a local water level datum. Regions covered by these vertical datum transformation models are limited and so would appear to constrain the areas where ellipsoid referenced surveys can be conducted. Because areas not covered by a vertical datum transformation model still …

Design And Implementation Of An Extensible Variable Resolution Bathymetric Estimator, Brian R. Calder, Glen Rice

Center for Coastal and Ocean Mapping

For grid-based bathymetric estimation techniques, determining the right resolution at which to work is essential. Appropriate grid resolution can be related, roughly, to data density and thence to sonar characteristics, survey methodology, and depth. It is therefore variable in almost all survey scenarios, and methods of addressing this problem can have enormous impact on the correctness and efficiency of computational schemes of this kind. This paper describes the design and implementation of a bathymetric depth estimation algorithm that attempts to address this problem by combining the computational efficiency of locally regular grids with piecewise-variable estimation resolution to provide a single …

The Radial Evolution Of Solar Wind Speeds, S. L. Mcgregor, W. J. Hughes, C. N. Arge, D. Odstrcil, Nathan A. Schwadron

Physics & Astronomy

The WSA-ENLIL model predicts significant evolution of the solar wind speed. Along a flux tube the solar wind speed at 1.0 AU and beyond is found to be significantly altered from the solar wind speed in the outer corona at 0.1 AU, with most of the change occurring within a few tenths of an AU from the Sun. The evolution of the solar wind speed is most pronounced during solar minimum for solar wind with observed speeds at 1.0 AU between 400 and 500 km/s, while the fastest and slowest solar wind experiences little acceleration or deceleration. Solar wind ionic …

Seafloor Characterization Using Airborne Hyperspectral Co-Registration Procedures Independent From Attitude And Positioning Sensors, Yuri Rzhanov, Shachak Pe'eri, James V. Gardner, James Guilford

Center for Coastal and Ocean Mapping

The advance of remote-sensing technology and data-storage capabilities has progressed in the last decade to commercial multi-sensor data collection. There is a constant need to characterize, quantify and monitor the coastal areas for habitat research and coastal management. In this paper, we present work on seafloor characterization that uses hyperspectral imagery (HSI). The HSI data allows the operator to extend seafloor characterization from multibeam backscatter towards land and thus creates a seamless ocean-to-land characterization of the littoral zone.

First Ibex Observations Of The Terrestrial Plasma Sheet And A Possible Disconnection Event, D. J. Mccomas, M. A. Dayeh, H. O. Funsten, S. A. Fuselier, J. Goldstein, J. M. Jahn, P. Janzen, D. G. Mitchell, S. M. Petrinec, D. B. Reisenfeld, Nathan A. Schwadron

Physics & Astronomy

The Interstellar Boundary Explorer (IBEX) mission has recently provided the first all-sky maps of energetic neutral atoms (ENAs) emitted from the edge of the heliosphere as well as the first observations of ENAs from the Moon and from the magnetosheath stagnation region at the nose of the magnetosphere. This study provides the first IBEX images of the ENA emissions from the nightside magnetosphere and plasma sheet. We show images from two IBEX orbits: one that displays typical plasma sheet emissions, which correlate reasonably well with a model magnetic field, and a second that shows a significant intensification that may indicate …

Remote Observations Of Ion Temperatures In The Quiet Time Magnetosphere, A. M. Keesee, N. Buzulukova, J. Goldstein, D. J. Mccomas, E. E. Scime, Harlan E. Spence, M. C. Fok, K. Tallaksen

Physics & Astronomy

[1] Ion temperature analysis of the first energetic neutral atom images of the quiet-time, extended magnetosphere provides evidence of multiple regions of ion heating. This study confirms the existence of a dawn-dusk asymmetry in ion temperature predicted for quiescent magnetospheric conditions by Spence and Kivelson (1993) and demonstrates that it is an inherent magnetospheric feature.

On-Line Planning And Scheduling: An Application To Controlling Modular Printers, Wheeler Ruml, Minh Binh Do, Rong Zhou, Markus P. J. Fromherz

Computer Science

We present a case study of artificial intelligence techniques applied to the control of production printing equipment. Like many other real-world applications, this complex domain requires high-speed autonomous decision-making and robust continual operation. To our knowledge, this work represents the first successful industrial application of embedded domain-independent temporal planning. Our system handles execution failures and multi-objective preferences. At its heart is an on-line algorithm that combines techniques from state-space planning and partial-order scheduling. We suggest that this general architecture may prove useful in other applications as more intelligent systems operate in continual, on-line settings. Our system has been used to …

Trends And Variability In Localized Precipitation Around Kibale National Park, Uganda, Africa, Mary D. Stampone, Joel N. Hartter, Colin A. Chapman, Sadie J. Ryan

Geography

Our objective was to understand and describe local spatial and temporal variability in precipitation around Kibale National Park, a tropical forest area of high conservation value. Continental or regional-scale trends are often relied upon to make policy and management decisions, but these analyses are often at too coarse a resolution to capture important variability at a finer scale where management actions operate. Monthly rainfall data derived from ten long-term station records (1941-1975) were used to evaluate local spatiotemporal variability in seasonal and annual rainfall for the area surrounding Kibale National Park. The magnitude, direction and significance of trends in seasonal …

Building A Model Of Collaboration Between Historically Black And Historically White Universities, Julie E. Williams, Cameron P. Wake, Linda Hayden, Eleanor Abrams, George C. Hurtt, Barrett Rock, Karen J. Graham, Stephen R. Hale, William Porter, Ronald Blackmon, Malcolm Lecompte, Darnell Johnson

Education

Despite increases over the last two decades in the number of degrees awarded to students from underrepresented groups in science, technology, engineering, and mathematics (STEM) disciplines, enhancing diversity in these disciplines remains a challenge. This article describes a strategic approach to this challenge—the development of a collaborative partnership between two universities: the historically Black Elizabeth City State University and the historically White University of New Hampshire. The partnership, a type of learning organization built on three mutually agreed upon principles, strives to enhance opportunities for underrepresented students to pursue careers in the STEM disciplines. This article further describes six promising …

An Equal Rights Amendment To Make Women Human, Ann Bartow

Law Faculty Scholarship

[Excerpt] “I can state with some authority that two times fourteen is twenty-eight, flouting the stereotype that women are inept at mathematics and simultaneously framing my argument in favor of an Equal Rights Amendment (ERA). Though the Fourteenth Amendment' provides women with partial legal armament (a dull sword, a small shield), equal protection requires something twice as powerful in the form of a Twenty-Eighth Amendment that would expressly vest women with equal rights under the law. The Fourteenth Amendment has completed only half of the job.”

Essential Fish Habitat Project Status Report, Jodi L. Pirtle, Christopher D. Wilson, Chris Rooper, Thomas C. Weber

Center for Coastal and Ocean Mapping

: Groundfish that associate with rugged seafloor types are difficult to assess with bottom-trawl sampling gear. Simrad ME70 multibeam echosounder (MBES) data and video imagery were collected to characterize trawlable and untrawlable areas, and to ultimately improve efforts to determine habitat-specific groundfish biomass. The data were collected during two acoustic-trawl surveys of the Gulf of Alaska (GOA) during 2011 and 2012 by NOAA Alaska Fisheries Science Center (AFSC) researchers. MBES data were collected continuously along the trackline, which included parallel transects (1-20 nmi spacing) and fine-scale survey locations in 2011. Video data were collected at camera stations using a drop …

Three Elements Of Self-Regulated Learning: Metacognitive Functioning, Self-Efficacy, And Study Behavior, Catherine E. Overson

Doctoral Dissertations

Individuals' metacognitive insight regarding their own performances -- what people think they know about what they know -- is often flawed. Students' metacognitive functioning was examined in two studies. In Study 1, exam performance estimates compared with actual scores were assessed across three in-class exams. Results demonstrated a systematic tendency for lower performers to overestimate their exam performances. Top performers underestimated their performance. In Study 2, an incentive to be as accurate as possible in exam performance estimations ($50 gift card) did not reduce estimation miscalculations for either bottom or top performers.

In Study 1, higher levels of students' self-efficacy …

Models And Methods For Computationally Efficient Analysis Of Large Spatial And Spatio-Temporal Data, Chengwei Yuan

Doctoral Dissertations

With the development of technology, massive amounts of data are often observed at a large number of spatial locations (n). However, statistical analysis is usually not feasible or not computationally efficient for such large dataset. This is the so-called "big n problem".

The goal of this dissertation is to contribute solutions to the "big n problem". The dissertation is devoted to computationally efficient methods and models for large spatial and spatio-temporal data. Several approximation methods to "the big n problem" are reviewed, and an extended autoregressive model, called the EAR model, is proposed as a parsimonious model that accounts for …

Proof And Reasoning In An Inquiry-Oriented Class: The Impact Of Classroom Discourse, Susan D. Generazzo

Doctoral Dissertations

Over the past decade, mathematics educators and researchers have become increasingly aware of the impact of social interactions on students' learning (NCTM, 2000; Bowers & Nickerson, 2001; Forman, 2003). Current research indicates that the classroom environment, including the activities and discussions that take place, can have a significant effect on the ways students make sense of mathematical concepts (Yackel, 2001). Understanding mathematics involves knowing how to make sense of key concepts through the processes of reasoning and justification. Educators and researchers agree on the importance of providing students with opportunities in class to explore, conjecture, and prove in order to …

The Deconstruction Of Ambition: Campus Climate, Stereotype Threat, And The Motivational Goals Of African American Students At A Selective Small Liberal Arts College, Roland S. Davis

Doctoral Dissertations

African American students face many challenges when they attend highly selective, predominantly White institutions. Lack of support for or belief in their academic success on the part of White faculty and peers may contribute to a climate in which it becomes increasingly difficult for African American students to be motivated and believe in their ability to excel academically. Studies suggest that an unsupportive racial climate on campus perpetuates "stereotype threat"---the conception that task performance can be affected by a fear of being evaluated on the basis of, or inadvertently perpetuating a stereotype about one's racial group, and a decade of …

Homotopy Mapping Spaces, Jeremy Brazas

Doctoral Dissertations

In algebraic topology, one studies the group structure of sets of homotopy classes of maps (such as the homotopy groups pin( X)) to obtain information about the spaces in question. It is also possible to place natural topologies on these groups that remember local properties ignored by the algebraic structure. Upon choosing a topology, one is left to wonder how well the added topological structure interacts with the group structure and which results in homotopy theory admit topological analogues. A natural place to begin is to view the n-th homotopy group pi n(X) as the quotient space of the iterated …

Wireless Sensor Integrated Tool For Characterization Of Machining Dynamics In Milling, Christopher Adam Suprock

Doctoral Dissertations

A first step towards practical sensing in the machining environment is the development and use of low cost, reliable sensors. Historically, the ability to record in-process data at an end mill tool tip has been limited by the sensor location. Often, these sensors are mounted on the material workpiece or the machine spindle at significant physical distance from the cutting process. Of specific interest are the problems of tool chatter which causes limitations to productivity and part quality. Although tool chatter is a substantial issue in machining, it remains an open research topic. In this research, a sensor integrated cutting …

Design Of A Low Power Switched-Capacitor Pipeline Analog-To-Digital Converter, Gang Chen

Doctoral Dissertations

An Analog to Digital Converter (ADC) is a circuit which converts an analog signal into digital signal. Real world is analog, and the data processed by the computer or by other signal processing systems is digital. Therefore, the need for ADCs is obvious.

In this thesis, several novel designs used to improve ADCs operation speed and reduce ADC power consumption are proposed. First, a high speed switched source follower (SSF) sample and hold amplifier without feedthrough penalty is implemented and simulated. The SSF sample and hold amplifier can achieve 6 Bit resolution with sampling rate at 10Gs/s.

Second, a novel …

Analytical And Numerical Prediction Of Localized Necking In Sheet Metal Forming Processes, Raed Zuhair Hasan

Doctoral Dissertations

The goal of this research is to investigate, develop and validate analytical and numerical tools that can accurately predict failure in sheet metal forming operations. The strain-based forming limit curve (FLC) is one of the tools to predict the maximum permissible strains of thin metallic sheets which are loaded in the plane of the sheet to different states of stress. It may be used to assess forming operations in the press shops as well as unintentional deformations, such as vehicle, aircraft, or train crashes. The accurate prediction of failure in sheet metal stamping can shorten product lead times, decrease tooling …
