A New Family Of Pr Two Channel Filter Banks, Jian-Ao Lian

Applications and Applied Mathematics: An International Journal (AAM)

A new family of multidimensional dimensional (MD) perfect reconstruction (PR) two channel filter banks with finite impulse response (FIR) filters induced from systems of biorthogonal MD scaling functions and wavelets are introduced. One of the advantages of this construction is that the biorthogonal scaling functions and wavelets are easy to establish due to the interpolatory property of the scaling functions to start with. The other advantage is that all filters can be centrosymmetric or bi-linear phase. Examples of two dimensional (2D) bi-linear phase PR twochannel FIR filter banks will be demonstrated.

Response Of Phlebotomine Sand Flies To Light-Emitting Diode-Modified Light Traps In Southern Egypt, D. F. Hoel, Emad Y. Fawaz, J.E Butler, N. Watany, S. S. El-Hossary, J. Villinski

United States Navy: Publications

Centers For Disease Control and Prevention (CDC) light traps were modified for use with light-emitting diodes (LED) and compared against a control trap (incandescent light) to determine the effectiveness of blue, green, and red lights against standard incandescent light routinely used for sand fly surveillance. Light traps were baited with dry ice and rotated through a 4 x 4 Latin square design during May, June, and July, 2006. Trapping over 12 trap nights yielded a total of 2,298 sand flies in the village of Bahrif, 6 km north of Aswan on the east bank of the Nile River in southern …

Computational Complexity Of Determining Which Statements About Causality Hold In Different Space-Time Models, Vladik Kreinovich, Olga Kosheleva

Departmental Technical Reports (CS)

Causality is one of the most fundamental notions of physics. It is therefore important to be able to decide which statements about causality are correct in different models of space-time. In this paper, we analyze the computational complexity of the corresponding deciding problems. In particular, we show that: for Minkowski space-time, the deciding problem is as difficult as the Tarski's decision problem for elementary geometry, while for a natural model of primordial space-time, the corresponding decision problem is of the lowest possible complexity among all possible spacetime models.

Detecting Weed Infestations In Soybean Using Remote Sensing., S. A. Clay, J. Chang, D. E. Clay, K. Dalstead

Agronomy, Horticulture and Plant Science Faculty Publications

Can weed distribution maps be developed from remote sensed reflectance data? When are the appropriate times to collect these data during the season? What wavebands can be used to distinguish weedy from weed- free areas? This research examined if and when reflectance could be used to distinguish between weed-free and weed-infested (mixed species) areas in soybean and to determine the most useful wavebands to separate crop, weed, and soil reflectance differences. Treatments in the two-year study included no vegetation (bare soil), weed-free soybean, and weed-infested soybean and, in one year, 80% corn residue cover. Reflectance was measured at several sampling …

Perceived Community Environment And Physical Activity Involvement In A Northern-Rural Aboriginal Community, Allison M. Kirby, Lucie Lévesque, Virginia Wabano, Jennifer Robertson-Wilson

Kinesiology and Physical Education Faculty Publications

Background: Type 2 diabetes disproportionately affects Aboriginal peoples in Canada. Ample evidence shows that regular physical activity (PA) plays an important role in the prevention and treatment of type 2 diabetes. Evidence is beginning to emerge linking PA to the physical environment but little is known about the relationship between remote rural environments and PA involvement in Aboriginal peoples. This study’s purpose was to investigate the relationship between perceptions of the environment and PA and walking patterns in Aboriginal adults in order to inform the planning and implementation of community-relevant PA interventions.

Methods: Two hundred and sixty three residents (133 …

Tennis, Anyone? Lessons On Innovation In A Mature Industry, Knowledge@Smu

Knowledge@SMU

Tennis qualifies as the oldest racquet sport in the world. Since 1874, little had changed until the 1970s when the wooden racquet was phased out, followed by a succession of cutting edge designs. How did the classic tennis racquet lend itself to being so thoroughly reinvented? Wharton management professor J.M. Pennings, together with Hann E Kim, professor at the KDI School of Public Policy and Management in Korea, set out to find some answers.

The Development Of Regional Regression Equations For Flood Flow Estimates Of Ungauged Streams In The State Of Arkansas, Stephen Mccall

Civil Engineering Undergraduate Honors Theses

The objective of this project is to improve the accuracy of the peak streamflow frequency estimates in ungauged streams by using a regionalization approach and the Bulletin 17B method of flood flow analysis. The entire state will be considered one region and the final results will be compared to previous studies done in the state. The data used will be the most up-to-date available from the USGS gauging stations around the state. This includes data from gauging stations that had less than 10 years of data when the last such study was conducted by Hodge & Tasker (1995). The data …

Lost And Found: (Re)-Placing Say Ka In The La Milpa Suburban Settlement Pattern, Jon B. Hageman, Brett A. Houk

Anthropology Faculty Publications

The site of Say Ka, less than 4 km from the major center of La Milpa, has generated a large degree of interest among researchers in northwestern Belize in part because of its elusiveness. After being recorded by archaeologists in 1990, Say Ka was "lost"; attempts to relocate it failed for nearly a decade (Figure I). It was fortuitously rediscovered in 1999, and three seasons of excavation began in 2004. This paper considers the history of Say Ka, its rediscovery, the results of initial excavations, and the possible implications of this minor center for studying the La Milpa suburban zone.

The Troublemaker's Friend: Retaliation Against Third Parties And The Right Of Association In The Workplace, Alex B. Long

Scholarly Works

Title VII theoretically provides virtually unlimited protection from retaliation for one kind of workplace troublemaker - the employee who files a formal charge of discrimination. However, the protection from retaliation enjoyed by such individuals is significantly less when the troublemaker resorts to an employer's internal process for resolving discrimination complaints prior to the filing of a formal charge of discrimination. And what of the coworker who assists the troublemaker in pursuing such an internal grievance? Or the coworker who simply has some type of relationship with the troublemaker who files a formal charge of discrimination? What protection from retaliation do …

Interval Computations And Interval-Related Statistical Techniques: Tools For Estimating Uncertainty Of The Results Of Data Processing And Indirect Measurements, Vladik Kreinovich

Departmental Technical Reports (CS)

In many practical situations, we only know the upper bound D on the (absolute value of the) measurement error d, i.e., we only know that the measurement error is located on the interval [-D,D]. The traditional engineering approach to such situations is to assume that d is uniformly distributed on [-D,D], and to use the corresponding statistical techniques. In some situations, however, this approach underestimates the error of indirect measurements. It is therefore desirable to directly process this interval uncertainty. Such "interval computations" methods have been developed since the 1950s. In this chapter, we provide a brief overview of related …

X-Rays From Magnetically Channeled Winds Of Ob Stars, In 'Magnetic Massive Stars', David H. Cohen

Physics & Astronomy Faculty Works

OB stars with strong radiation-driven stellar winds and large-scale magnetic fields generate strong and hard X-ray emission via the Magnetically Channeled Wind Shock (MCWS) mechanism. In this brief paper, I describe four separate X-ray diagnostics of the MCWS mechanism in OB stars, with applications to the prototype young O star, theta-1 Ori C.

Jane's Decision: Her Experience As A Plebe, Andra Gumbus, Jill Woodilla, Christopher C. York

Organization Management Journal

Jane (a pseudonym) describes her experience as a first year student at one of the military service academies sometime during the period 2000-2005. She portrays the rigors of training to be an officer in the US military service and the special burdens of being a good-looking, high-achieving woman in this environment. She provides an insider's perspective on the academy culture, including the importance of the honor code, and spoken and unspoken rules against fraternization and for protecting ―one's own. At the end of the case Jane must make a decision that could change the course of her life. The case …

The Future Of The Economic Analysis Of Law In Latin America: A Proposal For Model Codes, Juan Javier Del Granado, M. C. Mirow

Chicago-Kent Law Review

Nothing excites civilian lawyers and judges more than commissions for codification. Codification is more than an academic enterprise. Codification projects directly cut across the interface between law and life. ALACDE intends to harness this Latin American interest in codification to bring the economic approach to Latin America. A new-generation law and economics civil and commercial code will be a conscious project to restate Roman law's usefulness for coping with today's problems. Through law and economics, Roman law will renew itself. As a paradigmatic private-law system, Roman law is eminently amenable to a state-of-the-art fusion with law and economics. Sensitivity to …

X-Ray Emission From O Stars, David H. Cohen

Physics & Astronomy Faculty Works

Young O stars are strong, hard, and variable X-ray sources, properties which strongly affect their circumstellar and galactic environments. After ~1 Myr, these stars settle down to become steady sources of soft X-rays. I use high-resolution X-ray spectroscopy and MHD modeling to show that young O stars like theta-1 Ori C are well explained by the magnetically channeled wind shock scenario. After their magnetic fields dissipate, older O stars produce X-rays via shock heating in their unstable stellar winds. Here too I use X-ray spectroscopy and numerical modeling to confirm this scenario. In addition to elucidating the nature and cause …

The Effects Of Attentional Focus And Expertise Level On Self-Selected Exercise Intensity, Melissa Abo

Masters Theses & Specialist Projects

The purpose of this study was to investigate the effects of being prompted to focus on self-talk versus bodily sensations on exercise intensity chosen by participants and level of enjoyment. One hundred and forty-two undergraduate psychology students ran on a treadmill for 20 minutes on two separate days, one week apart. One day they were asked to focus on their bodily sensations and on another day positive self-talk. The order of these assigned focuses was counterbalanced. Participant's current level of exercise activity (Stage of Change) was used as an independent variable. The dependent variables of interest were self-selected exercise intensity …

Automatically Extract Information From Web Documents, Dipesh Sharma

Masters Theses & Specialist Projects

The Internet could be considered to be a reservoir of useful information in textual form — product catalogs, airline schedules, stock market quotations, weather forecast etc. There has been much interest in building systems that gather such information on a user's behalf. But because these information resources are formatted differently, mechanically extracting their content is difficult. Systems using such resources typically use hand-coded wrappers, customized procedures for information extraction. Structured data objects are a very important type of information on the Web. Such data objects are often records from underlying databases and displayed in Web pages with some fixed templates. …

The Influence Of Adolescents' Educational Aspirations And Religiosity On The Desire To Marry Among High School Seniors, Erica Scott

Masters Theses & Specialist Projects

The present study uses data from the 2004 Monitoring the Future Survey (MTF) to evaluate how twelfth grader's educational aspirations and religiosity influenced their desire to marry. Previous research indicates that education attained and increased religiosity increases the probability of marriage (Bumpass, Sweet, and Cherlin 1991; Goldstein and Kenney 2001; Sweeney 2002; Thornton, Axinn, and Teachman 1995). Exchange theory explains that higher levels of education increase one's odds in the marriage market, and the actual act of marriage is perceived as a "reward" to highly religious individuals (Becker 1973; Blau 1964; Edwards 1969; Friedman and Hechter 1988; Homans 1974). Results …

Commuting Analysis In A Small Metropolitan Area - A Case Study Of Bowling Green/Warren County, Kentucky, Caitlin Hagar

Masters Theses & Specialist Projects

In previous studies of urban commutes, little attention has been paid to commute patterns in smaller urban areas. In this study, the concept of "excess commute" (EC) is applied to the Bowling Green-Warren County Metropolitan Statistical Area (BGWCMSA) in Kentucky. EC quantifies the portion of commute distance explained by the overall spatial separation of jobs and households. Results in this thesis research show that approximately 65% of commute distance by persons driving alone in the study area can be explained by the physical locations of homes relative to job sites as well as the existing roadway network, leaving an EC …

Gender, Attitudes, And Perceptions Of Workplace Incivility, Christopher C. Brady

Masters Theses & Specialist Projects

The purpose of the present study was to examine perceptions of workplace incivility as a function of observers’ gender, observers’ gender-related attitudes, and the gender of the instigator and target of the mistreatment. The study included data from 102 (65% female, 90% white) participants from various occupations and backgrounds across the United States. Participants completed a web-based survey that consisted of scenarios of uncivil interactions, gender-attitudes, and various demographic information. Results suggest that observers’ gender and gender-related attitudes are important factors in how they perceive workplace incivility. Results also suggest that the gender of those involved in uncivil interactions is …

Classification And Biogeography Of New World Grasses: Anomochlooideae, Pharoideae, Ehrhartoideae, And Bambusoideae, Emmet J. Judziewicz, Lynn G. Clark

Aliso: A Journal of Systematic and Floristic Botany

Molecular data support Anomochlooideae and Pharoideae as the two most basal extant clades within Poaceae. Anomochlooideae are endemic to the New World and have two tribes and two genera including the widespread Streptochaeteae (3–4 spp.) and the critically endangered Anomochloeae (1 sp.) of coastal Bahia, Brazil. Pharoideae are pantropical with one tribe, three genera, and 14 species; all eight species of Pharus occur only in the New World. Bambusoideae and Ehrhartoideae are sister groups and together form a clade sister to Pooideae, although support for this set of relationships is low. Ehrhartoideae are a worldwide subfamily represented in the New …
