Upper Limit Map Of A Background Of Gravitational Waves, B. P. Abbott, R. Abbott, Mario C. Diaz, R. Grosso, Soumya Mohanty, Soma Mukherjee, Cristina V. Torres Oct 2007

Upper Limit Map Of A Background Of Gravitational Waves, B. P. Abbott, R. Abbott, Mario C. Diaz, R. Grosso, Soumya Mohanty, Soma Mukherjee, Cristina V. Torres

Physics & Astronomy Faculty Publications

We searched for an anisotropic background of gravitational waves using data from the LIGO S4 science run and a method that is optimized for point sources. This is appropriate if, for example, the gravitational wave background is dominated by a small number of distinct astrophysical sources. No signal was seen. Upper limit maps were produced assuming two different power laws for the source strain power spectrum. For an f−3 power law and using the 50 Hz to 1.8 kHz band the upper limits on the source strain power spectrum vary between 1.2×10−48  Hz−1 (100  Hz/f)3 and 1.2×10−47  Hz−1 (100  Hz/f)3, …

Searches For Periodic Gravitational Waves From Unknown Isolated Sources And Scorpius X-1: Results From The Second Ligo Science Run, B. P. Abbott, R. Abbott, Mario C. Diaz, R. Grosso, Wm. R. Johnston, Soumya Mohanty, Soma Mukherjee, Cristina V. Torres

Physics & Astronomy Faculty Publications

We carry out two searches for periodic gravitational waves using the most sensitive few hours of data from the second LIGO science run. Both searches exploit fully coherent matched filtering and cover wide areas of parameter space, an innovation over previous analyses which requires considerable algorithm development and computational power. The first search is targeted at isolated, previously unknown neutron stars, covers the entire sky in the frequency band 160–728.8 Hz, and assumes a frequency derivative of less than 4×10−10  Hz/s. The second search targets the accreting neutron star in the low-mass x-ray binary Scorpius X-1 and covers the frequency …

Six Degrees Of Cass Sunstein, Tracey E. George, Paul H. Edelman Oct 2007

Six Degrees Of Cass Sunstein, Tracey E. George, Paul H. Edelman

Vanderbilt Law School Faculty Publications

Degrees of separation is a concept that is intuitive and appealing in popular culture as well as academic discourse: It tells us something about the connectedness of a particular field. It also reveals paths of influence and access. Paul Erdős was the Kevin Bacon of his field - math - coauthoring with a large number of scholars from many institutions and across subfields. Moreover, his work was highly cited and important. Mathematicians talk about their Erdős number (i.e., numbers of degrees of separation) as a sign of their connection to the hub of mathematics: An Erdős number of 2 means …

Investigating A Method To Measure Sperm Transfer In Chelidonura Sandrana (Opisthobranchia: Cephalaspidea), Kate Kunigelis Oct 2007

Investigating A Method To Measure Sperm Transfer In Chelidonura Sandrana (Opisthobranchia: Cephalaspidea), Kate Kunigelis

Independent Study Project (ISP) Collection

This paper investigates possible methods for measuring sperm transfer in the internal fertilizing, simultaneous hermaphrodite Chelidonura sandrana (Opisthobranchia: Cephalaspidea). Comparing sperm amount transferred in copulations has significance for testing the assumption that sperm transfer is linearly correlated with copulation duration as well as providing a tool for future studies. Various methods of preparing, treating, and viewing sperm samples were attempted. Two unsuccessful pilot studies were conducted to test free sperm counts and measuring sperm pellet surface area. Future research should focus on optimizing centrifugation method for surface area measurements of sperm clusters and resuspending sperm clusters to enable sperm counting. …

Dust in galaxies can be mapped either by the FIR/submillimeter emission, the optical or infrared reddening of starlight, or the extinction of a known background source. We compare two dust extinction measurements for a set of 15 sections in 13 nearby galaxies to determine the scale of the dusty interstellar medium ( ISM ) responsible for disk opacity: one using stellar reddening and the other a known background source. In our earlier papers, we presented extinction measurements of 29 galaxies, based on calibrated counts of distant background objects identified though foreground disks in Hubble Space Telescope WFPC2 images. For the …

Risk, Trade, Recovery And The Consideration Of Real Options: The Imperative Coordination Of Policy, Marketing, And Finance In The Wake Of Catastrophe, Mark R. Manfredo, Clifford J. Shultz Oct 2007

Risk, Trade, Recovery And The Consideration Of Real Options: The Imperative Coordination Of Policy, Marketing, And Finance In The Wake Of Catastrophe, Mark R. Manfredo, Clifford J. Shultz

School of Business: Faculty Publications and Other Works

Recovery from societal and market catastrophe is a daunting process requiring multi-function, systemic, and long-term efforts. Humanitarian aid and donor assistance rarely are sufficient. Trade and other forms of direct investment in devastated markets offer another kind of recovery-assistance. Risks encountered in recovering economies however can deter firms wishing to invest. A real options framework is applied to examine the financial feasibility of trading with recovering economies; the framework is applied to the countries of the war-disintegrated, former Yugoslavia. The real options framework considers the value of managerial flexibility in the presence of risks. Implications for policy, marketing management and …

Digital Generation Pre-Service Teachers As Change Agents: A Paradox, Sharn Donnison Oct 2007

Digital Generation Pre-Service Teachers As Change Agents: A Paradox, Sharn Donnison

Australian Journal of Teacher Education

In this paper I examine the assumptions or ‘cultural models’ (Gee, 1992, p. 60) that 70 aspiring Digital Generation pre-service teachers in south-east Queensland have formed about themselves as future teachers. This paper is drawn from a larger study that focused on the cultural models and resulting discourses that these pre-service teachers expressed about the development of their future lives and careers. In this paper, I argue that these pre-service teachers possess conflicting cultural models about both themselves as teaching professionals and as social activists. While they profess to be educational and social change agents they also profess discourses of …

Turkish Pre-Service Teachers' Beliefs About The Importance Of Teaching Chemistry, Esen Uzuntiryaki, Yezdan Boz Oct 2007

Turkish Pre-Service Teachers' Beliefs About The Importance Of Teaching Chemistry, Esen Uzuntiryaki, Yezdan Boz

Australian Journal of Teacher Education

The purpose of this study was to describe Turkish pre-service chemistry teachers’ beliefs about the importance of teaching chemistry in high schools. For this purpose, 45 pre-service chemistry teachers were administered a questionnaire involving open-ended questions which asked what the importance of teaching chemistry is, and why we teach chemistry in high schools. Based on the written responses, 12 pre-service teachers were chosen to be interviewed to obtain more elaborated information about their beliefs. Data analysis revealed that most of the pre-service teachers expressed that chemistry should be taught in order to explain daily life events. However, a very small …

Variable Check-In Time: Raising Room Revenue With Multiple Daily Check-In Times, Matthew Kaplan Oct 2007

Variable Check-In Time: Raising Room Revenue With Multiple Daily Check-In Times, Matthew Kaplan

UNLV Theses, Dissertations, Professional Papers, and Capstones

An exploration of a new theory of hotel room valuation and pricing called “Variable Check-In Time”. The theory holds that hotels could increase room revenue by instituting multiple daily check-in times, rather than the typical, universal 3:00 p.m. to 12:00 p.m. room-day. In doing so, hotels could accommodate guests for more hours per day, thus raising the room night’s salable value. The paper presents the concept of the room-hour and of room-hour utility, making a quantitative case for increased room revenue on utility-maximization grounds. A model for the optimization of room-hour utility is presented, as well as a demonstration of …

Benthic Mapping For Habitat Classification In The Peconic Estuary: Phase I Groundtruth Studies, Robert M. Cerrato, Nicole P. Maher

School of Marine & Atmospheric Sciences Faculty Publications

Benthic habitat maps of the estuary seafloor will increase our knowledge of range and variability in benthic habitats, will assist managers in their efforts to protect and/or restore commercially and recreationally important finfish and shellfish, will link land usage (e.g. developed vs. undeveloped areas) and water quality data to benthic habitat quality, and will make it possible to utilize faunal data as a long-term indicator of the overall “health” of the estuary. We are developing benthic habitat maps by combining high-resolution remote sensing techniques with detailed study of the physical and faunal characteristics at point locations in different seafloor environments. …

Neighborhood Defined Adaboost Based Mixture Of Color Components For Efficient Skin Segmentation, Ramya Reddy Maaram Oct 2007

Neighborhood Defined Adaboost Based Mixture Of Color Components For Efficient Skin Segmentation, Ramya Reddy Maaram

Electrical & Computer Engineering Theses & Dissertations

A skin segmentation algorithm robust to illumination changes and skin-like backgrounds is developed in this thesis. So far skin pixel classification has been limited to only individual color spaces and there has not been a comprehensive evaluation of which color components or combination of color components would provide the best classification accuracy, Color components in a given color space form the feature set for the classification of skin pixels. The combination of the color components or the features present within a single color space may not be the best when it comes to skin pixel classification as the discriminatory power …

Salt Fluxes At The Chesapeake Bay Entrance, Ruth Lane Oct 2007

Salt Fluxes At The Chesapeake Bay Entrance, Ruth Lane

OES Theses and Dissertations

Underway measurements of salinity and flow profiles were used to compute salt fluxes at the mouth of the Chesapeake Bay in spring and summer. Waters were sampled along a cross-bay transect over four tidal cycles in 1997: at the end of April, during neap tides, and in mid-July, during spring tides. Data were interpolated onto a uniform grid along the transect area. A least squares regression with semidiurnal and diurnal harmonics was fit on both salinity and flow at each point of the grid to separate tidal from non-tidal influences. The results of the least squares fit were used to …

A Modular Kernel Linear Discriminant Analysis Of Gabor Features For Improved Face Recognition, Neeharika Gudur Oct 2007

A Modular Kernel Linear Discriminant Analysis Of Gabor Features For Improved Face Recognition, Neeharika Gudur

Electrical & Computer Engineering Theses & Dissertations

Automatic face recognition is one of the major challenges in computer vision and pattern analysis. This thesis presents an efficient face recognition system that is robust with regards to changes in illumination, facial expressions and partial occlusions. Modular Kernel Linear Discriminant Analysis performed on Gabor Features obtained from the face images is employed for improving face recognition accuracy. A face image is pre-processed using the 2D Gabor wavelet transform to achieve invariance to illumination in images. Modular approaches that divide the pre-processed images into smaller sub-images provide improved accuracy, as the facial variations in an image are confined to local …

Analysis Of Two-Dimensional High-Energy Photoelectron Momentum Distributions In The Single Ionization Of Atoms By Intense Laser Pulses, Zhangjin Chen, Toru Morishita, Anh-Thu Le, C. D. Lin Oct 2007

Analysis Of Two-Dimensional High-Energy Photoelectron Momentum Distributions In The Single Ionization Of Atoms By Intense Laser Pulses, Zhangjin Chen, Toru Morishita, Anh-Thu Le, C. D. Lin

Physics Faculty Research & Creative Works

We analyzed the two-dimensional (2D) electron momentum distributions of high-energy photoelectrons of atoms in an intense laser field using the second-order strong field approximation (SFA2). The SFA2 accounts for the rescattering of the returning electron with the target ion to first order and its validity is established by comparing with results obtained by solving the time-dependent Schrödinger equation for short pulses. By analyzing the SFA2 theory, we confirmed that the yield along the back rescattered ridge in the 2D momentum spectra can be interpreted as due to the elastic scattering in the backward directions by the returning electron wave packet. …
