Application Of Inversions To Lossless Image Compression, Ziya Arnavut

Department of Electrical and Computer Engineering: Faculty Publications

Linear prediction schemes, such as that of the Joint Photographic Experts Group (JPEG), are simple and normally produces a residual sequence with lower zero-order entropy. Occasionally the entropy of the prediction error becomes greater than that of the original image. Such situations frequently occur when the image data have discrete gray levels located within certain intervals. To alleviate this problem, various authors have suggested different preprocessing methods. However, the techniques reported require two passes. We extend the definition of Lehmer-type inversions (Lehmer 1960 and 1964) from permutations to multiset permutations and present a one-pass algorithm based on inversions of a …

The Challenge Of Waste Stewardship And Sustainable Development: A Study Of Municipal Waste Management In Rural Manitoba, C. Emdad Haque, Karen T. Hamberg

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Despite the recent enactment of federal and provincial reduction targets, the majority of government and private sector research has focused primarily on household recycling strategies while little attention was given to other dimensions critical to the achievement of sustainable waste management. Although distinct problems may exist in rural jurisdictions, the literature continues to address the problems inherent in the management of wastes in urban centers rather than rural communities. The aim of this research was to close this gap by examining the issue of municipal waste management in rural Manitoba. Special emphasis was placed upon: (1) the amount and type …

Review Of Conservation Of Great Plains Ecosystems: Current Science, Future Options, Edited By S. R. Johnson And Aziz Bouzaher, David J. Wishart

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

This book stems from a symposium entitled "Conservation of Great Plains Ecosystems: Current Science, Future Options" held in Kansas City in April of 1993, the purpose of which was to forge a "Great Plains regional environmental initiative." The editors explain what this means in an introduction that also summarizes the book's contents and offers recommendations: only with integrated community-based management of identifiable ecosystems, they argue, can the Great Plains avoid further severe ecological distress. The most highly touted word in the volume is "sustainability," the most castigated, "monoculture." And who could disagree with that?

Conservation of Great Plains Ecosystems is …

South Dakota Gaming: A Regional Analysis, Erin Hogan Fouberg

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

The referendum and initiative processes were used six times between 1982 and 1994 to address the issue of gaming in South Dakota. Four of the six votes resulted in pro-gaming outcomes. This study examines how and why voters in the state 50 sixty-six counties varied geographically in their levels of gaming support over time. Five different ways of regionalizing the state are advanced as possible explanations, and then analyzed using maps, analysis of variance tests, and eta correlation coefficients. The popular East River-West River cultural-political divide is found to serve as the best explanation of the geographical distribution of gaming …

Review Of Archaeology And Geographical Information Systems: A European Perspective, Luann Wandsnider

Department of Anthropology: Faculty Publications

Although but six years old, our library copy of Interpreting Space: GIS and Archaeology (1990; edited by Allen, Stanton, and Zubrow) is tattered and in need of rebinding. Such has been the interest in this volume and its subject, the adaptation of Geographic Information System (GIs) technology to archaeological needs. Archaeology and Geographical information Systems complements Interpreting Space in several ways. Where the latter features mostly North American authors, European authors are the main contributors to the former. An4 in an effort to educate readers, the first offers brief reviews of hardware, software, and GIS concepts; such items are mentioned …

Review Of Losing Asia: Modernization And The Culture Of Development, By Brett Wallach., Robert Stoddard

Geography Program: Faculty Publications

When I first visited Kathmandu in the mid-1950s, the shops sold mostly local and Indian products, many of the shoppers wore Newari dress, and motor vehicles were uncommon. In the evening, one could leisurely stroll the quiet streets and gaze at temple tops silhouetted against a starlit sky. A couple of decades later, after the drug culture and other foreign interests had invaded and infected the capital city, a nighttime stroller encountered some of the same dangers on the street that occur in American cities at night. Upon my return to Kathmandu last winter, I observed retail stores, citizens' dress, …

A Space-Time Stochastic Climatological Approach To Daily Global Solar Radiation, Istvan Matyasovszky, Istvan Boragdi

Department of Civil and Environmental Engineering: Faculty Publications

A stochastic climatological model is presented to describe the space-time behavior of daily global solar radiation measured by pyranometeres. Due to the differently of describing daily global radiation by common probability distributions, a non-parametric technique , the Abramson kernel estimator, is used. The space-time climatological model of daily global radiation consists of a transformed multivariate auto-regressive (AR) process conditioned on large-scale atmospheric circulation patterns. The transformation is necessary to establish a relationship between the probability distribution of global radiation and a normal variable used in AR model. In order to check the stochastic model a simulation study was performed for …

Application Of Permutations To Lossless Compression Of Multispectral Thematic Mapper Images, Ziya Arnavut, Sunil Narumalani

Department of Earth and Atmospheric Sciences: Faculty Publications

The goal of data compression is to find shorter representa- tions for any given data. In a data storage application, this is done in order to save storage space on an auxiliary device or, in the case of a communication scenario, to increase channel throughput. Because re- motely sensed data require tremendous amounts of transmission and storage space, it is essential to find good algorithms that utilize the spa- tial and spectral characteristics of these data to compress them. A new technique is presented that uses a spectral and spatial correlation to create orderly data for the compression of multispectral …

Regional Zooarchaeology And Global Change: Problems And Potentials, Thomas Amorosi, James Woollett, Sophia Perdikaris, Thomas Mcgovern

School of Global Integrative Studies: Faculty Publications

Zooarchaeology is a potentially critical tool for the reconstruction of past regional landscapes. The subfield is increasingly being asked to contribute to long-term studies of human interaction with the environment associated with national and international investigations of past and future global change. Intersite comparison of animal bone collections (archaeofaunas) is central to such regional approaches. However, zooarchaeologists have identified many factors of deposition, attrition, recovery, and analysis that might appear to make such comparisons problematic. Using selected examples drawn from the North Atlantic and Eastern Arctic, this paper suggests that, while intersite comparison is not a trivial problem, it may …

Changes In Drought Policies In New Zealand, Heather J. Keen, Lynmore Rotorua

Drought Network News (1994–2001)

New Zealand, lying in the South Pacific Ocean approximately 1,200 miles east of Australia, is subject to recurring droughts. Its two main islands are long and narrow, with high mountain ranges and hill country bisecting them from north to south. The predominant westerly winds, along with the mountain ranges and hill country, produce a marked orographic effect. Thus, the western side of the country, in general, records significantly higher annual average rainfall totals than does land on the eastern side.

The country has experienced a number of severe droughts throughout its history, especially in the east, where a number of …

Review Of Peopling The Plains: Who Settled Where In Frontier Kansas By James Shortridge, D. Aidan Mcquillan

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Kansas was born in the bloody prelude to the Civil War, a contested territory between North and South. The settlement frontier had penetrated only the eastern third of the state before war broke out; the western two-thirds saw the frontier push westward for several decades after the war, from 1865 to 1885. In the state's extreme western parts the frontier expanded and contracted several times between 1890 and 1930. James Shortridge sets out to explore the origins of Kansas cultural geography with such questions as: Who were these "first effective" settlers on the Kansas frontier? Where did they come from? …

Niches Of Homelessness In Rural Nebraska: Bolstering Existing Understandings, Sharon Lord Gaber

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Rural homelessness, particularly in the Great Plains region, is under-researched. Most current understandings of homelessness are based on research in metropolitan regions. This paper suggests that the general structural frameworks. which have been developed to model homelessness in metropolitan areas. can serve as a useful starting point for understanding rural homelessness in Nebraska. By using a "key informant" survey of homeless service providers in Nebraska it is clear that there are several niches of homeless persons (Native Americans, migrant workers. meat-packing workers, and transients) present in Nebraska that are not discussed in the existing literature.

Leisure And Aging In Southern Saskatchewan, Ralph Nilson, David Weaver, Carlton Yoshioka

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

This study examined the psychological and socio-economic dimensions of the leisure experience patterns of the expanding older adult population in the Canadian Great Plains or Prairie region. Survey data were collected from a random sample of 2,969 of persons 65 years of age and older residing in southern Saskatchewan. Results indicated that older adults have a wide range of leisure activities with involvement in numerous individual and community related pursuits. However, when differentiated by season, winter activities tended to be passive, solitary, inexpensive, and home-based activities. Moreover, important psychological dimensions in perceived health and activity of older adults did not …

Review Of Atlas Of Oklahoma Climate By Howard L. Johnson And Claude E. Duchon, John A. Harrington Jr.

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Thematic atlases depicting aspects of past weather events and climatic summaries are an important resource for researchers, educators, and the general public. The authors of the Atlas of Oklahoma Climate have produced an engaging text providing a good overview of a subject about which both are highly knowledgeable: Howard Johnson serves as an Assistant State Climatologist in the Oklahoma Climatological Survey; Claude Duchon is a Professor in the School of Meteorology at the University of Oklahoma.

The atlas is divided into six major sections: an "Introduction"; "Geography and Oklahoma's Weather and Climate"; "Annual Climate"; "Seasonal Climate"; "Wind and Humidity"; and …

Molecular Systematics Of The Fruit Bat, Artibeus Jamaicensis: Origin Of An Unusual Island Population, Dorothy E. Pumo, Iksoo Kim, James Remsen, Carleton J. Phillips, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

DNA sequences from mitochondrial tRNA genes, the light strand replication site, and a region of the 12s rRNA gene were used to test the hypothesis that the unusual Antillean island subspecies, Artibeus jamaicensis schwartzi, was derived from a South American origin. Parsimony and bootstraping analyses allied the mitochondrial genome in these bats with mitochondrial DNA (mtDNA) isolated from Artibeus planirostris living in French Guiana rather than with mtDNA isolated from Artibeus jamaicensis from the Antilles or Mexico. Although the tRNA sequences differed slightly, the 12s rRNA sequences were identical in mtDNA isolated from A. j. schwartzi on St. Vincent …

Operational Control Of The Brown Tree Snake On Guam, Thomas C. Hall

Vertebrate Pest Conference Proceedings: 17th (1996)

An operational control program for brown tree snakes (Boiga irregularis) on Guam began in April 1993. The program focused on minimizing the dispersal of brown tree snakes to other Pacific islands and the U.S. mainland. During the first year of operation, more than 3,000 snakes were caught within a kilometer of high risk port facilities using traps, detector dogs, and spotlighting. Additionally, habitat modifications and prey-base removal were used to reduce the attractiveness of these facilities to brown tree snakes. Public awareness was also an important part of the program such as the education of cargo packers, shippers, …

Chronology For Fluctuations In Late Pleistocene Sierra Nevada Glaciers And Lakes, Fred M. Phillips, Marek G. Zreda, Larry Benson, Mitchell A. Plummer, David Elmore, Pankaj Sharma

United States Geological Survey: Staff Publications

Mountain glaciers, because of their small size, are usually close to equilibrium with the local climate and thus should provide a test of whether temperature oscillations in Greenland late in the last glacial period are part of global-scale climate variability or are restricted to the North Atlantic region. Correlation of cosmogenic chlorine-36 dates on Sierra Nevada moraines with a continuous radiocarbon-dated sediment record from nearby Owens Lake shows that Sierra Nevada glacial advances were associated with Heinrich events 5, 3, 2, and 1.

The Ampato Textile Offerings, William J. Conklin

Textile Society of America: Symposium Proceedings

The term "sacred" in our symposium title implies the existence of "secular" and thus conceptually divides the world into a dualism which is characteristic of Western thought. Perhaps though, that is not the way the ancient Andeans, whose textiles we are to briefly examine, saw their world. They did not divide the world into animate and inanimate, into flora and fauna, or neatly into secular and sacred. Everything was a living, interactive part of their cosmos and every textile, regardless of its rank, was considered to be spirited. With last year's discovery of a fully clothed 13 year old Inka …

Mari Sandoz's Portrait Of An Artist's Youth: Robert Henri's Nebraska Years, Helen Winter Stauffer

Great Plains Quarterly (through 2013)

Robert Henri's life story would have appealed to Mari Sandoz even if he were not an important early twentieth-century American artist. Robert Henri (born Robert Henry Cozad) came from a time, a place, and a family that at first glance seem unlikely to have produced an avant garde painter of landscapes, cityscapes, and portraits; it was the sort of paradox Sandoz liked to explore. That Henri had spent much of his youth in her native Nebraska in a family headed by a magnetic and dominating man not unlike her own father also interested her. That the family left Nebraska in …

Review Essay: Undaunted Courage: Meriwether Lewis, Thomas Jefferson, And The Opening Of The American West By Stephen E. Ambrose, John L. Allen

Great Plains Quarterly (through 2013)

From time to time, a serious book excites the imaginations of a vaster public than the audience of scholarly journals. Because the Center for Great Plains Studies has, over the past sixteen years, sponsored the reediting and publication of The Journals of the Lewis & Clark Expedition, we could not help but notice the enormous popular success of Stephen Ambrose's Undaunted Courage: Meriwether Lewis, Thomas Jefferson, and the Opening of the American West. To provide a focus on some of the scholarly concerns raised by this new text, we invited three prominent scholars to review the book from …
