Valley Splitting In Low-Density Quantum-Confined Heterostructures Studied Using Tight-Binding Models, Timothy B. Boykin, Gerhard Klimeck, Mark Friesen, S. N. Coppersmith, Paul Von Allmen, Seungwon Lee, Fabiano Oyafuso

Other Nanotechnology Publications

A detailed study of reduced-basis tight-binding models of electrons in semiconducting quantum wells is presented. The focus is on systems with degenerate valleys, such as silicon in silicon germanium heterostructures, in the low-density limit, relevant to proposed quantum computing architectures. Analytic results for the bound states of systems with hard-wall boundaries are presented and used to characterize the valley splitting in silicon quantum wells. The analytic solution in a no-spin-orbit model agrees well with larger tight-binding calculations that do include spin-orbit coupling. Numerical investigations of the valley splitting for finite band offsets are presented that indicate that the hard-wall results …

Supersymmetry In Quantum Mechanics: An Extended View, A. R.P. Rau

Faculty Publications

The concept of supersymmetry in a quantum-mechanical system is extended, permitting the recognition of more supersymmetric systems, including very familiar ones such as the free particle. Its spectrum is shown to be supersymmetric upon taking into account physical reasonableness of the wavefunctions involved. Spacetime symmetries are used for the construction of the supercharges without explicit invocation of fermionic or Grassmann variables. Most notably, while the free particle in one dimension has generally been regarded as having a doubly degenerate continuum throughout, the construction clarifies that there is a single zero-energy state at the base of the spectrum.

Problems With The Dartmouth Wireless Snmp Data Collection, Tristan Henderson, David Kotz

Computer Science Technical Reports

The original Dartmouth wireless network study used SNMP to query the college's Cisco 802.11b access points. The perl scripts that performed the SNMP queries suffered from some problems, in that they queried inappropriate SNMP values, or misunderstood the meaning of other values. This data was also used in a subsequent analysis. The same scripts were used to collect data for a subsequent study of another wireless network. This document outlines these problems and indicates which of the data collected by the original scripts may be invalid.

Evaluating The Use Of Morphometric Measurements From Museum Specimens For Sex Determination In Mountain Plovers (Charadrius Montanus), William M. Iko, Stephen J. Dinsmore, Fritz L. Knopf

Western North American Naturalist

The Mountain Plover (Charadrius montanus) is a shorebird species endemic to the dry, terrestrial ecosystems of the Great Plains and southwestern United States. Breeding Bird Survey data suggest that Mountain Plover populations have declined by >60% in the last 30 years. A better understanding of the population dynamics of the Mountain Plover is important in determining future management goals for this species. However, this effort is hampered by the inability to determine the sex of Mountain Plovers accurately under field conditions. In an effort to develop a simple method for sexing plovers in the hand, we measured external …

Native Plant Community Composition And Genetic Diversity Associated With Long-Term Weed Invasions, Brian A. Mealor, Ann L. Hild, Nancy L. Shaw

Western North American Naturalist

Many studies have assessed genetic changes in exotic plant species in their native and introduced ranges, but none have focused on genetic variation in native plant species in response to exotic invasion. We examine characteristics of native plant communities within and outside old (>25 year) invasions of Acroptilon repens (Russian knapweed) and Cardaria draba (hoary cress). We also document genetic variability of 4 native grass populations (Hesperostipa comata [needle and thread], Achnatherum hymenoides [Indian ricegrass], Sporobolus airoides [alkali sacaton], and Poa secunda [Sandberg bluegrass]) from 2 areas: adjacent to and within weed invasions. Native plant species richness and …

Nanoscale Hydrophobic Interaction And Nanobubble Nucleation, T. Koishi, S. Yoo, K. Yasuoka, Xiao Cheng Zeng, T. Narumi, R. Susukita, A. Kawai, H. Furusawa, A. Suenaga, N. Okimoto, N. Futatsugi, T. Ebisuzaki

Xiao Cheng Zeng Publications

We report large-scale atomistic simulation of midrange nanoscale hydrophobic interaction, manifested by the nucleation of nanobubble between nanometer-sized hydrophobes at constrained equilibrium. When the length scale of the hydrophobes is greater than 2 nm, the nanobubble formation shows hysteresis behavior resembling the first-order transition. Calculation of the potential of mean force versus interhydrophobe distance provides a quantitative measure of the strength of the nanoscale hydrophobic interaction.

The Relationship Among Various Learner Characteristics And Reading Achievement As Measured By The Florida Comprehensive Assessment Test, Amanda A. Privé

USF Tampa Graduate Theses and Dissertations

The present study examined the relationships among various learner characteristics and reading achievement, as measured by the Florida Comprehensive Assessment Test (FCAT). Using a multiple regression, the independent variables grade, gender, ethnicity, and motivation to read were used to predict the dependent variable, reading achievement. Participants in this study consisted of 585 students from nine elementary, nine middle, and nine high schools across three districts in Florida.

Using archival data from a database composed by the Florida Center for Reading Research, the FCAT and Motivation to Read Profile were used to compute reading achievement and motivation to read, respectively. FCAT …

The Next Edition Of Iho-S-57 (4.0): A Primer, Lee Alexander

Center for Coastal and Ocean Mapping

The International Hydrographic Organization (IHO) is an intergovernmental consultative and technical organization that was established in 1921 to support the safety of navigation and the protection of the marine environment. IHO Special Publication 57 (IHO S-57) is the IHO Transfer Standard for Digital Hydrographic Data. It is the standard to be used for the exchange of digital hydrographic data between hydrographic offices (HOs), and for the distribution of hydrographic data to manufacturers, mariners and other data users (e.g., GIS). It was developed so that the transfer all forms of hydrographic data would take place in a consistent and uniform manner. …

Dynamical Epidemic Suppression Using Stochastic Prediction And Control, Ira Schwartz, Lora Billings, Erik Bollt

Department of Mathematics Faculty Scholarship and Creative Works

We consider the effects of noise on a model of epidemic outbreaks, where the outbreaks appear randomly. Using a constructive transition approach that predicts large outbreaks prior to their occurrence, we derive an adaptive control scheme that prevents large outbreaks from occurring. The theory is applicable to a wide range of stochastic processes with underlying deterministic structure.

Application Of Support Vector Machines And Neural Networks In Digital Mammography: A Comparative Study, Nivedita V. Candade

USF Tampa Graduate Theses and Dissertations

Microcalcification (MC) detection is an important component of breast cancer diagnosis. However, visual analysis of mammograms is a difficult task for radiologists. Computer Aided Diagnosis (CAD) technology helps in identifying lesions and assists the radiologist in making his final decision.

This work is a part of a CAD project carried out at the Imaging Science Research Division (ISRD), Digital Medical Imaging Program, Moffitt Cancer Research Center, Tampa, FL. A CAD system had been previously developed to perform the following tasks: (a) pre-processing, (b) segmentation and (c) feature extraction of mammogram images. Ten features covering spatial, and morphological domains were extracted …

Adapting The Green And Ampt Model To Account For Air Compression And Counterflow, Darwiche Sabeh

USF Tampa Graduate Theses and Dissertations

One of the earliest functions to express infiltration as a function of time was introduced by Green and Ampt. In this study their formula was modified to account for air compression and counterflow. Physically,infiltration, air compression, and counterflow occur simultaneously, while in this model they are decoupled within a time step. Counterflow is calculated as a mass flux and pressure is found using the perfect gas law. First, a comparison of three infiltration methods, the original Green and Ampt formulation, a modified version incorporating air compression only, and the third version including air compression and counterflow, was conducted. Then sensitivity …

Systemic Reform In A Federated System: Los Angeles At The Turn Of The Millennium, David Menefee-Libey

Education Policy Analysis Archives (EPAA)

I synthesize some of the lessons we have learned about systemic school reform in order and derive two explicit hypotheses about when such reforms are likely to be more and less successful. The first hypothesis focuses on program implementation: to achieve success, any systemic reform must overcome challenges at each stage of the policy-making process, from agenda-setting to policy choice to implementation. The second hypothesis focuses on the federated nature of education policy- making in the United States: any successful systemic reform must offer a program that aligns local efforts with state and sometimes federal policy. ...
