Shape Invariance And The Exactness Of Quantum Hamilton-Jacobi Formalism, Charles Cherqui, Yevgeny Binder, Asim Gangopadhyaya Sep 2007

Shape Invariance And The Exactness Of Quantum Hamilton-Jacobi Formalism, Charles Cherqui, Yevgeny Binder, Asim Gangopadhyaya

Physics: Faculty Publications and Other Works

Quantum Hamilton-Jacobi Theory and supersymmetric quantum mechanics (SUSYQM) are two parallel methods to determine the spectra of a quantum mechanical systems without solving the Schr ̈odinger equation. It was recently shown that the shape invariance, which is an integrability condition in SUSYQM formalism, can be utilized to develop an iterative algorithm to determine the quantum momentum functions. In this paper, we show that shape invariance also suffices to determine the eigenvalues in Quantum Hamilton-Jacobi Theory.

Polymorphic Indian Ricegrass Populations Result From Overlapping Waves Of Migration, T. A. Jones, M. G. Redinbaugh, S. R. Larson, Y. Zhang, B. D. Dow Sep 2007

Polymorphic Indian Ricegrass Populations Result From Overlapping Waves Of Migration, T. A. Jones, M. G. Redinbaugh, S. R. Larson, Y. Zhang, B. D. Dow

Western North American Naturalist

Indian ricegrass (Achnatherum hymenoides [Roem. & Schult.] Barkworth) is a rangeland species native to western North America with populations that may exhibit distinct seed-size morphs borne on separate plants. These morphs are often associated with very different levels of seed dormancy. We compared RAPD profiles of the relatively infrequent and highly dormant jumbo seed morph to its more germinable small or large (non-jumbo) companion seed morphs collected from 9 sites where they were sympatric. Jumbo seed accessions from 9 additional sites that did not exhibit seed polymorphism were included to better sample this seed morph across the species' range. …

Quantitative Study With Prospective Students: Final Report, The Lawlor Group

Data

In February of 2007, Illinois Wesleyan University (Bloomington, Illinois) retained The Lawlor Group (TLG) to conduct an Identity Assessment assignment as one part of its overall strategic planning effort. The purpose of the assignment is to help IWU better understand its identity and obtain a “collective sense of self” as it embarks on a new strategic plan. As part of that assignment—and to augment the investigation and information gathering for the overall assignment—TLG conducted a web survey with prospective students. This research was intended to supplement our qualitative efforts during the site visit and provide quantitative data to support or …

A Utile Function Optimizer, James Carroll, Christopher K. Monson, Kevin Seppi Sep 2007

A Utile Function Optimizer, James Carroll, Christopher K. Monson, Kevin Seppi

Faculty Publications

We recast the problem of unconstrained continuous evolutionary optimization as inference in a fixed graphical model. This approach allows us to address several pervasive issues in optimization, including the traditionally difficult problem of selecting an algorithm that is most appropriate for a given task. This is accomplished by placing a prior distribution over the expected class of functions, then employing inference and intuitively defined utilities and costs to transform the evolutionary optimization problem into one of active sampling. This allows us to pose an approach to optimization that is optimal for each expressly stated function class. The resulting solution methodology …

Blueprint For Iteratively Hardening Power Grids Employing Unified Power Flow Controllers, William M. Siever, Ann K. Miller, Daniel R. Tauritz Sep 2007

Blueprint For Iteratively Hardening Power Grids Employing Unified Power Flow Controllers, William M. Siever, Ann K. Miller, Daniel R. Tauritz

Electrical and Computer Engineering Faculty Research & Creative Works

A stable electricity supply is vital for modern society. However, many parts of our power transmission grid are operating near their operational limits. Such stressed systems are vulnerable to cascading failures, where a few small faults can induce a cascade of failures potentially leading to a major blackout The unified power flow controller (UPFC), the most powerful highspeed, semi-conductor based power flow device, can be used as a theoretical model to study how these devices can be used to improve power grid resilience. The blueprint presented here can be used to iteratively identify critical weaknesses in power grids and to …

Yasir: A Low-Latency, High-Integrity Security Retrofit For Legacy Scada Systems, Patrick P. Tsang, Sean W. Smith Sep 2007

Yasir: A Low-Latency, High-Integrity Security Retrofit For Legacy Scada Systems, Patrick P. Tsang, Sean W. Smith

Computer Science Technical Reports

We construct a bump-in-the-wire (BITW) solution that retrofits security into time-critical communications over bandwidth-limited serial links between devices in Supervisory Control And Data Acquisition (SCADA) systems. Previous BITW solutions fail to provide the necessary security within timing constraints; the previous solution that does provide the necessary security is not BITW. At a comparable hardware cost, our BITW solution provides sufficient security, and yet incurs minimal end-to-end communication latency. A microcontroller prototype of our solution is under development.

Enhancement Of Nd: Yag Libs Emission Of A Remote Target Using A Simultaneous Co/Sub 2/ Laser Pulse, Dennis K. Killinger, Susan D. Allen, Robert D. Waterbury, Chris Stefano, Edwin L. Dottery

Publications

For the first time to the best of our knowledge, a simultaneous 10.6 μm CO2 laser pulse has been used to enhance the Laser Induced Breakdown Spectroscopy (LIBS) emission from a 1.064 μm Nd:YAG laser induced plasma on a hard target. The enhancement factor was on the order of 25 to 300 times, depending upon the emission lines observed. For an alumina ceramic substrate the Al emission lines at 308 nm and Fe impurity line at 278 nm showed an increase of 60x and 119x, respectively. The output energy of the Nd:YAG laser was 50 mJ/pulse focused to a 1 …

A Probabilistic Approach To Measuring Robustness In Computing Systems, Behdis Eslamnour, Shoukat Ali Sep 2007

A Probabilistic Approach To Measuring Robustness In Computing Systems, Behdis Eslamnour, Shoukat Ali

Electrical and Computer Engineering Faculty Research & Creative Works

System builders are becoming increasingly interested in robust design. We believe that a methodology for generating robustness metrics will help the robust design research efforts and, in general, is an important step in the efforts to create robust computing systems. the purpose of the research in this paper is to quantify the robustness of a resource allocation, with the eventual objective of setting a standard that could easily be instantiated for a particular computing system to generate a robustness metric. We present our theoretical foundation for a robustness metric and give its instantiation for a particular system. © 2007 IEEE.

Using Lax Scintillator In A New Low-Background Compton Telescope, James M. Ryan, Peter F. Bloser, John R. Macri, Mark L. Mcconnell Sep 2007

Using Lax Scintillator In A New Low-Background Compton Telescope, James M. Ryan, Peter F. Bloser, John R. Macri, Mark L. Mcconnell

Space Science Center

The ability of Compton telescopes to perform imaging and spectroscopy in space depends directly on the speed and energy resolution of the calorimeter detectors in the telescope. The calorimeter detectors flown on space-borne or balloon-borne Compton telescopes have included NaI(Tl), CsI(Na), HPGe and liquid organic scintillator. By employing LaX scintillators for the calorimeter, one can take advantage of the unique speed and resolving power of the material to improve the instrument sensitivity and simultaneously enhance its spectroscopic performance and thus its imaging performance. We present a concept for a space-borne Compton telescope that employs LaX as a calorimeter and estimate …

Gauge-Gravity Duality -- Super Yang Mills Quantum Mechanics, Simon Catterall, Toby Wiseman Sep 2007

Gauge-Gravity Duality -- Super Yang Mills Quantum Mechanics, Simon Catterall, Toby Wiseman

Physics - All Scholarship

We describe the conjectured holographic duality between Yang-Mills quantum mechanics and type IIa string theory. This duality allows us to use lattice Monte Carlo simulations to probe the physics of the gravitational theory - for example, at low energies it provides a computation of black hole entropy in terms of a sum over microstates of the dual gauge theory. Numerical results are presented of the 4 supercharge theory at finite temperature.

Lighting And Optical Tools For Image Forensics, Micah Kimo Johnson Sep 2007

Lighting And Optical Tools For Image Forensics, Micah Kimo Johnson

Dartmouth College Ph.D Dissertations

We present new forensic tools that are capable of detecting traces of tampering in digital images without the use of watermarks or specialized hardware. These tools operate under the assumption that images contain natural properties from a variety of sources, including the world, the lens, and the sensor. These properties may be disturbed by digital tampering and by measuring them we can expose the forgery. In this context, we present the following forensic tools: (1) illuminant direction, (2) specularity, (3) lighting environment, and (4) chromatic aberration. The common theme of these tools is that they exploit lighting or optical properties …

Probing The Ground State In Gauge Theories, T Heinzl, A Ilderton, K Langfeld, M Lavelle, W Lutz, D Mcmullan Sep 2007

Probing The Ground State In Gauge Theories, T Heinzl, A Ilderton, K Langfeld, M Lavelle, W Lutz, D Mcmullan

School of Engineering, Computing and Mathematics

We consider two very different models of the flux tube linking two heavy quarks: a string linking the matter fields and a Coulombic description of two separately gauge invariant charges. We compare how close they are to the unknown true ground state in compact U(1) and the SU(2) Higgs model. Simulations in compact U(1) show that the string description is better in the confined phase but the Coulombic description is best in the deconfined phase; the last result is shown to agree with analytical calculations. Surprisingly in the non-abelian theory the Coulombic description is better in both the Higgs and …

Gopherus Polyphemus (Gopher Tortoise) Mortality, Richard M. Engeman, Henry T. Smith, Gregory S. Kaufman Sep 2007

Gopherus Polyphemus (Gopher Tortoise) Mortality, Richard M. Engeman, Henry T. Smith, Gregory S. Kaufman

United States Department of Agriculture Wildlife Services: Staff Publications

Gopherus polyphemus has declined precipitously in range and numbers in Florida and recently was state-listed as a "threatened" species under the Florida Wildlife Code (Chap. 39, Florida Administrative Code). At ca. 1000 h on 27 July 2006, GK observed a 23 cm carapace length male G. polyphemus between the North- South railroad tracks on the eastern boundary of Savannas Preserve State Park (SPSP) in St. Lucie County, Florida (Fig. 1). The tortoise seemed uninjured, but was deceased. Eastern Box Turtles (Terrapene carolina) were recently shown to have great difficulty escaping railroad tracks, with overheating to critical levels likely …

Domestic Health Hazard And Indoor Air-Pollution: An Approach To Find Alternative Energy Source For Rural Bangladesh To Minimize The Threat, Reazul S.M. Ahsan, Jinia Afrin Sep 2007

Domestic Health Hazard And Indoor Air-Pollution: An Approach To Find Alternative Energy Source For Rural Bangladesh To Minimize The Threat, Reazul S.M. Ahsan, Jinia Afrin

Himalayan Research Papers Archive

Indoor air pollution and health hazards for women and child especially in the developing countries have been overlooked for decades. It happened because there was no specific indoor pollution standard and alternative energy solution to minimize the indoor gaseous emissions at the domestic end-use level of energy. Traditional biomass fuel is one of the major sources of energy in the developing countries. About 2.4 billion people rely on traditional biomass, mainly for cooking and heating as they have limited access to better alternative energy sources like Natural Gas or Electricity. In Bangladesh per capita energy consumption is only 8.83 GJ …

A Determination Of The Spin-Orbit Alignment Of The Anomalously Dense Planet Orbiting Hd 149026, Aaron S. Wolf, Gregory Laughlin, Gregory W. Henry, Debra A. Fischer, Geoffrey W. Marcy, R. Paul Butler, Steve Vogt Sep 2007

A Determination Of The Spin-Orbit Alignment Of The Anomalously Dense Planet Orbiting Hd 149026, Aaron S. Wolf, Gregory Laughlin, Gregory W. Henry, Debra A. Fischer, Geoffrey W. Marcy, R. Paul Butler, Steve Vogt

Information Systems and Engineering Management Research Publications

We report 35 radial velocity measurements of HD 149026 taken with the Keck Telescope. Of these measurements, 15 were made during the transit of the companion planet HD 149026b, which occurred on 2005 June 25. These velocities provide a high-cadence observation of the Rossiter-McLaughlin effect, the shifting of photospheric line profiles that occurs when a planet occults a portion of the rotating stellar surface. We combine these radial velocities with previously published radial velocity and photometric data sets and derive a composite best-fit model for the star-planet system. This model confirms and improves previously published orbital parameters, including the remarkably …
