Milliwatt Power Deep Ultraviolet Light-Emitting Diodes Over Sapphire With Emission At 278 Nm, J. P. Zhang, A. Chitnis, V. Adivarahan, S. Wu, V. Mandavilli, R. Pachipulusu, M. Shatalov, Grigory Simin, J. W. Yang, M. Asif Khan Dec 2002

Milliwatt Power Deep Ultraviolet Light-Emitting Diodes Over Sapphire With Emission At 278 Nm, J. P. Zhang, A. Chitnis, V. Adivarahan, S. Wu, V. Mandavilli, R. Pachipulusu, M. Shatalov, Grigory Simin, J. W. Yang, M. Asif Khan

Faculty Publications

We report on AlGaN multiple-quantum-well (MQW)-based deep ultraviolet light-emitting diodes over sapphire with peak emission at 278 nm. A new buffer layer growth process was used to reduce the number of defects and hence the nonradiative recombination. The improved material quality and carrier confinement resulted in pulsed powers as high as 3 mW at 278 nm and a significantly reduced deep-level-assisted long-wavelength emission.

Search For The Production Of Single Sleptons Through R-Parity Violation In Pp̅ Collisions At √S = 1.8 Tev, V. M. Abazov, Gregory R. Snow, D0 Collaboration Dec 2002

Search For The Production Of Single Sleptons Through R-Parity Violation In Pp̅ Collisions At √S = 1.8 Tev, V. M. Abazov, Gregory R. Snow, D0 Collaboration

Gregory Snow Publications

We report the first search for supersymmetric particles via s-channel production and decay of smuons or muon sneutrinos at hadronic colliders. The data for the two-muon and two-jets final states were collected by the D0 experiment and correspond to an integrated luminosity of 94 ± 5 pb-1. Assuming that R parity is violated via the single coupling λ′211, the number of candidate events is in agreement with expectation from the standard model. Exclusion contours are given in the (m0; m½) and (mΧ̅,mν planes for λ′ …

Valley Floor Climate Observations From The Mcmurdo Dry Valleys, Antarctica, 1986-2000, Peter T. Doran, Christopher P. Mckay, Gary D. Clow, Gayle L. Dana, Andrew G. Fountain, Thomas H. Nylen, W. Berry Lyons Dec 2002

Valley Floor Climate Observations From The Mcmurdo Dry Valleys, Antarctica, 1986-2000, Peter T. Doran, Christopher P. Mckay, Gary D. Clow, Gayle L. Dana, Andrew G. Fountain, Thomas H. Nylen, W. Berry Lyons

Geography Faculty Publications and Presentations

Climate observations from the McMurdo dry valleys, East Antarctica are presented from a network of seven valley floor automatic meteorological stations during the period 1986 to 2000. Mean annual temperatures ranged from −14.8°C to −30.0°C, depending on the site and period of measurement. Mean annual relative humidity is generally highest near the coast. Mean annual wind speed increases with proximity to the polar plateau. Site to site variation in mean annual solar flux and PAR is due to exposure of each station and changes over time are likely related to changes in cloudiness. During the non-summer months, strong katabatic winds …

A Planet At 5 Au Around 55 Cancri, Geoffrey W. Marcy, R. Paul Butler, Debra A. Fischer, Greg Laughlin, Steve S. Vogt, Gregory W. Henry, Dimitri Pourbaix Dec 2002

A Planet At 5 Au Around 55 Cancri, Geoffrey W. Marcy, R. Paul Butler, Debra A. Fischer, Greg Laughlin, Steve S. Vogt, Gregory W. Henry, Dimitri Pourbaix

Information Systems and Engineering Management Research Publications

We report precise Doppler-shift measurements of 55 Cancri (G8 V) obtained from 1989 to 2002 at Lick Observatory. The velocities reveal evidence for an outer planetary companion to 55 Cancri orbiting at 5.5 AU. The velocities also confirm a second, inner planet at 0.11 AU. The outer planet is the first extrasolar planet found that orbits near or beyond the orbit of Jupiter. It was drawn from a sample of ~50 stars observed with sufficient duration and quality to detect a giant planet at 5 AU, implying that such planets are not rare. The properties of this Jupiter analog may …

Chaotic Free-Space Laser Communication Over Turbulent Channel, N. F. Rulkov, Mikhail Vorontsov, L. Illing Dec 2002

Chaotic Free-Space Laser Communication Over Turbulent Channel, N. F. Rulkov, Mikhail Vorontsov, L. Illing

Electro-Optics and Photonics Faculty Publications

The dynamics of errors caused by atmospheric turbulence in a self-synchronizing chaos-based communication system that stably transmits information over a ∼5  km free-space laser link is studied experimentally. Binary information is transmitted using a chaotic sequence of short-term pulses as a carrier. The information signal slightly shifts the chaotic time position of each pulse depending on the information bit. We report the results of an experimental analysis of the atmospheric turbulence in the channel and the impact of turbulence on the bit-error-rate performance of this chaos-based communication system.

How Massive Single Stars End Their Life, A. Heger, C. L. Fryer, S. E. Woosley, N. Langer, Dieter H. Hartmann Dec 2002

How Massive Single Stars End Their Life, A. Heger, C. L. Fryer, S. E. Woosley, N. Langer, Dieter H. Hartmann

Publications

How massive stars die - what sort of explosion and remnant each produces - depends chiefly on the masses of their helium cores and hydrogen envelopes at death. For single stars, stellar winds are the only means of mass loss, and these are chiefly a function of the metallicity of the star. We dicuss how meallicity, and a simplified prescription for its effect on mass loss, affects the evolution and final fate of massive stars. We map, as a function of mass and metallicity, where black holes and neutron stars are likely to form and where different types of supernovae …

He Ii Reverberation In Active Galactic Nucleus Spectra, Mark C. Bottorff, Jack A. Baldwin, Gary J. Ferland, Jason W. Ferguson, Kirk T. Korista Dec 2002

He Ii Reverberation In Active Galactic Nucleus Spectra, Mark C. Bottorff, Jack A. Baldwin, Gary J. Ferland, Jason W. Ferguson, Kirk T. Korista

Physics and Astronomy Faculty Publications

This paper compares the observed reverberation response lags and the intensity ratios of the broad-line region (BLR) emission lines He II λ1640, He II λ4686, and C IV λ1549 with predictions. Published observations indicate that the He II λ1640 lag is 3 times shorter than the lags of He II λ4686 or C IV λ1549. Diverse models, however, do not reproduce this observation. Extensive improved numerical simulations of the hydrogenic isoelectronic sequence emission show that the He II spectrum remains especially simple, even in the central regions of a luminous quasar. Line trapping never builds up a significant population of …

The Third Side Of The Coin, Tamara Wells-Banar Dec 2002

The Third Side Of The Coin, Tamara Wells-Banar

LSU New Orleans Theses and Dissertations

The Third Side of the Coin is a manuscript of poetry exploring ironic distances, both physical and metaphysical, both slight and significant. It opens with a quote from Agha Shahid Ali who asked, "What then is separation's geography?" The poems in this collection describe the geography of separation between individuals, cultures, ideas, man and nature and the physical and metaphysical realms. As the author travels deserts, oceans, and outer space, she seeks proofs of existence and questions natural laws deemed irrefutable. This questioning is reflected in the book's title, which, on one hand, represents a state of geometric impossibility. And …

Virtual Fetal Pig Dissection As An Agent Of Knowledge Acquisition And Attitudinal Change In Female High School Biology Students, Rebecca Maloney Dec 2002

Virtual Fetal Pig Dissection As An Agent Of Knowledge Acquisition And Attitudinal Change In Female High School Biology Students, Rebecca Maloney

LSU New Orleans Theses and Dissertations

One way to determine if all students can learn through the use of computers is to introduce a lesson taught completely via computers and compare the results with those gained when the same lesson is taught in a traditional manner. This study attempted to determine if a virtual fetal pig dissection can be used as a viable alternative for an actual dissection for females enrolled in high school biology classes by comparing the knowledge acquisition and attitudinal change between the experimental (virtual dissection) and control (actual dissection) groups. Two hundred and twenty four students enrolled in biology classes in a …

When Urban Education Meets Community Activism: A Case Of Student Empowerment In New Orleans, Lisa Richardson Dec 2002

When Urban Education Meets Community Activism: A Case Of Student Empowerment In New Orleans, Lisa Richardson

LSU New Orleans Theses and Dissertations

This is an ethnographic study of urban education and community development in the city of New Orleans. In New Orleans, as in all American cities, the public schools are at the center of local politics and the policies that affect community life. Institutions of public education have come under fire for failing to prepare youth to compete in the global economy. This is particularly true in urban communities, where schools serve a higher proportion of students of color facing greater incidences of poverty, underemployment and economic distress. As education policymakers and business leaders look to improve education, many of the …

Characteristics Of Quasi-Monochromatic Gravity Waves Observed With Na Lidar In The Mesopause Region At Starfire Optical Range, Nm, Xiong Hu, Alan Z. Liu, Chester S. Gardner, Gary R. Swenson Dec 2002

Characteristics Of Quasi-Monochromatic Gravity Waves Observed With Na Lidar In The Mesopause Region At Starfire Optical Range, Nm, Xiong Hu, Alan Z. Liu, Chester S. Gardner, Gary R. Swenson

Physical Sciences - Daytona Beach

The University of Illinois Na wind/temperature lidar data collected at the Starfire Optical Range, NM, between Jan. 1998 and May 2000 was used to extract the dominant monochromatic gravity waves. By using simultaneously measured horizontal wind and temperature profiles, the vertical wavelengths (λz), (TI), and propagation directions were determined using the hodograph method. A total of 700 monochromatic gravity waves were analyzed from ~300 h of observations. It was found that 84.4% of the waves were propagating upwards. The mean λz was 12.6 km and 9.9 km for upward and downward propagating waves, respectively, and …

On The Effect Of Random Errors In Gridded Bathymetric Compilations, Martin Jakobsson, Brian R. Calder, Larry A. Mayer Dec 2002

On The Effect Of Random Errors In Gridded Bathymetric Compilations, Martin Jakobsson, Brian R. Calder, Larry A. Mayer

Center for Coastal and Ocean Mapping

We address the problem of compiling bathymetric data sets with heterogeneous coverage and a range of data measurement accuracies. To generate a regularly spaced grid, we are obliged to interpolate sparse data; our objective here is to augment this product with an estimate of confidence in the interpolated bathymetry based on our knowledge of the component of random error in the bathymetric source data. Using a direct simulation Monte Carlo method, we utilize data from the International Bathymetric Chart of the Arctic Ocean database to develop a suitable methodology for assessment of the standard deviations of depths in the interpolated …

A Service Discovery-Enabled Lcd Projector Device, Jeevan Kale

LSU New Orleans Theses and Dissertations

The widespread deployment of inexpensive communications technology, computational resources in the networking infrastructure and network-enabled end devices pose a problem for end users: how to locate a particular network service or device out of those accessible. Service providers use Service Discovery Services (SDS) to advertise the descriptions of available or already running services, while clients use SDS to compose queries for locating these services. Service descriptions and queries use the eXtensible Markup Language (XML) to encode vendor specific information and device- or service-specific capabilities as well as the actions addressed to the device or service. This report presents the architecture …
