Liability For Global Navigation Satellite Services: A Comparative Analysis Of Gps And Galileo, Frans Von Der Dunk Jan 2004

Liability For Global Navigation Satellite Services: A Comparative Analysis Of Gps And Galileo, Frans Von Der Dunk

Space, Cyber, and Telecommunications Law Program: Faculty Publications

The law relating to global navigation satellite systems, (GNSS) is a novel and complex subject. As a result, this paper addresses a considerable number of issues from a new, as of yet untested legal perspective. It will also address a number of altogether new issues which, from a legal perspective, have been dealt with often in other areas of law. Global navigation satellite systems are being used for a very rapidly growing plethora of applications and, thus, also cause a rapidly growing plethora of legal issues to arise. These range from general institutional and jurisdictional ones, to such concrete aspects …

An Association Of Benthic Foraminifera And Gypsum In Holocene Sediments Of Estuarine Chesapeake Bay, Usa, John Cann, Thomas Cronin Jan 2004

An Association Of Benthic Foraminifera And Gypsum In Holocene Sediments Of Estuarine Chesapeake Bay, Usa, John Cann, Thomas Cronin

United States Geological Survey: Staff Publications

Two cores of Holocene sediments recovered from the Cape Charles Channel of Chesapeake Bay yielded radiocarbon ages of about 6.8 to 5.8 ka for the lower intervals. Fossil foraminifera preserved in these lower sediments are dominated by species of Elphidium, which make up about 90% of the assemblage throughout, and probably signify deposition in hypersaline waters. Buccella frigida and Ammonia beccarii are the only other species commonly present. Hypersalinity of bottom waters seems to have been maintained by water-density stratification in a basin-like section of the channel. In core PTXT -4-P-I transition to modem Chesapeake conditions, in which numbers …

In Situ Stress, Fracture, And Fluid Flow Analysis In Well 38c-9: An Enhanced Geothermal System In The Coso Geothermal Field, Judith M. Sheridan, Stephen H. Hickman Jan 2004

In Situ Stress, Fracture, And Fluid Flow Analysis In Well 38c-9: An Enhanced Geothermal System In The Coso Geothermal Field, Judith M. Sheridan, Stephen H. Hickman

United States Geological Survey: Staff Publications

Geoscientists from the Coso Operating Company, EGI-Utah, GeoMechanics International, and the United States Geological Survey are cooperating in a multi-year study to develop an Enhanced Geothermal System (EGS) in the Coso Geothermal Field. Key to the creation of an EGS is an understanding of the relationship among natural fracture distribution, fluid flow, and the ambient tectonic stresses that exist within the resource in order to design a hydraulic and thermal stimulation of an east-flank injection well, the first step in the creation of a heat exchanger at depth. Well datasets from the east flank of the Coso Geothermal Field are …

Field Validation Of Burned Area Reflectance Classification (Barc) Products For Post Fire Assessment, Andrew T. Hudak, Pete Robichaud, Jeffrey S. Evans, Jess Clark, Keith Lannom, Penelope Morgan, Carter Stone Jan 2004

Field Validation Of Burned Area Reflectance Classification (Barc) Products For Post Fire Assessment, Andrew T. Hudak, Pete Robichaud, Jeffrey S. Evans, Jess Clark, Keith Lannom, Penelope Morgan, Carter Stone

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The USFS Remote Sensing Applications Center (RSAC) and the USGS EROS Data Center (EDC) produce Burned Area Reflectance Classification (BARC) maps for use by Burned Area Emergency Rehabilitation (BAER) teams in rapid response to wildfires. BAER teams desire maps indicative of soil burn severity, but photosynthetic and non-photosynthetic vegetation also influences the spectral properties of post-fire imagery. Our objective was to assess burn severity both remotely and on the ground at six 2003 wildfires. We analyzed fire effects data from 34 field sites located across the full range of burn severities observed at the Black Mountain Two, Cooney Ridge, Robert, …

Product Innovation In Financial Services: A Survey, Christopher O'Brien Jan 2004

Product Innovation In Financial Services: A Survey, Christopher O'Brien

Journal of Actuarial Practice (1993–2006)

This paper considers product innovation in insurance and other financial services, an area where actuaries have an important role. It considers the proposition that there is no unique formula for success and that what works well in one situation may not work well in another. It first examines the sources of ideas for new products and, in particular, the role played by consumers, which is generally regarded as weak. It then looks at how ideas are implemented, with particular importance attributed to cross-functional teams and the formality of the product development process. Then it considers how success is measured (with …

Great Plains Ecosystems: Past, Present, And Future, Fred B. Samson, Fritz L. Knopf, Wayne Ostlie Jan 2004

Great Plains Ecosystems: Past, Present, And Future, Fred B. Samson, Fritz L. Knopf, Wayne Ostlie

United States Geological Survey: Staff Publications

Little questions exists that the main bodies of North American prairie (i.e., the tall-grass, mixed, and shortgrass) are among the most endangered resources on the continent. The purpose of this paper is to provide a past and present biological base- line by which to understand North American prairies and to provide a platform for future conservation. Events both immediate to the end of the Pleistocene and historic suggest that the present grassland conditions are different from those within which most of the grassland organisms evolved. Our analysis suggests that few grassland landscapes remain adequate in area and distribution to sustain …

Comparison Of Three Methods Of Size Grading Channel Catfish Stockers, Bartholomew W. Green, David L. Heikes, Andrew E. Goodwin Jan 2004

Comparison Of Three Methods Of Size Grading Channel Catfish Stockers, Bartholomew W. Green, David L. Heikes, Andrew E. Goodwin

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The stocking of size-graded catfish into production ponds should increase production efficiency, but grading large numbers of fish with existing technology is laborious. We evaluated the effectiveness of a mechanical grader recently developed at the University of Arkansas at Pine Bluff (UAPB) relative to that of box and sock graders and assessed injuries sustained by stocker channel catfish Ictalurus punctatus during grading. Three 0.25-acre ponds were stocked at 11,777 lb/acre. Initial total length (TL) ranged from 6.3 to 15.7 in, and initial weight of individuals ranged from 0.04 to 1.10 lb. The fish population in each pond was divided into …

Systemic Nesting Among The Anasazi: Ad 900-1140, Carl G. Drexler Jan 2004

Systemic Nesting Among The Anasazi: Ad 900-1140, Carl G. Drexler

Nebraska Anthropologist

Over the past 150 years, archaeologists have proposed a number of models and hypotheses to explain the growth andfluorescence of the Anasazi system based in Chaco Canyon, New Mexico. This paper gives an overview of some of those models, then explores how World System Theory (WSJ) might be used to understand the social and economic processes at work during the pinnacle of settlement in Chaco Canyon.

Review Of Fighting For The Farm: Rural America Transformed Edited By Jane Adams, John C. Allen Jan 2004

Review Of Fighting For The Farm: Rural America Transformed Edited By Jane Adams, John C. Allen

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

Fighting for the Family Farm brings together the contributions of scholars from several disciplines to provide an overview of political processes within North American agriculture.
Beginning in the Imperial Valley of California, Alan Rudy provides a well-documented snapshot of state and federal governments' roles in changing the face of agricultural support of industrial food and fiber production models. Rudy illustrates how ecological damage and state policies converge to shape new agricultural policies, arguing that a spatio-temporal construct is necessary for determining responses to the many forms of ecological, social, and infrastructural crisis as well as fir more fully understanding how …

Continuum Modeling Of Cell Membranes, Eveline Baesu, R. E. Rudd, J. Belak, M. Mcelfresh Jan 2004

Continuum Modeling Of Cell Membranes, Eveline Baesu, R. E. Rudd, J. Belak, M. Mcelfresh

Department of Engineering Mechanics: Faculty Publications

In this paper, we develop a finite-deformation model for cell membranes with a view toward characterizing the local mechanical response of membranes in atomic force microscope (AFM) experiments. The membrane is modeled as a 2-D fluid continuum endowed with bending resistance. The general theory is used to obtain equations that describe axisymmetric equilibrium states. The membrane is assumed to enclose a fluid medium, which transmits hydrostatic pressure to the membrane, and a point load is applied at the pole to simulate an AFM probe. Both types of loading are associated with a potential and the problem is then cast in …

Triangulating Faculty Needs For The Assessment Of Student Learning, D. Lynn Sorenson, Timothy W. Bothell Jan 2004

Triangulating Faculty Needs For The Assessment Of Student Learning, D. Lynn Sorenson, Timothy W. Bothell

To Improve the Academy: A Journal of Educational Development

To enhance assessment of student learning, the Brigham Young University (BYU) Faculty Center undertook a needs assessment to guide new initiatives. Researchers reviewed results from the National Survey of Student Engagement and an earlier BYU faculty survey. In addition, they conducted a qualitative study with faculty and administrators. The qualitative study can serve as a model for other faculty developers considering new initiatives. The findings raised thought-provoking issues for faculty development, particularly faculty readiness. As a result of this research, the center bolstered current services and developed new ones to support the assessment of student learning.

Low-Frequency Surface Wave Propagation And The Viscoelastic Behavior Of Porcine Skin, Donald D. Duncan, Sean J. Kirkpatrick, Li Fang Jan 2004

Low-Frequency Surface Wave Propagation And The Viscoelastic Behavior Of Porcine Skin, Donald D. Duncan, Sean J. Kirkpatrick, Li Fang

Electrical and Computer Engineering Faculty Publications and Presentations

A physical model describing the propagation of lowfrequency surface waves in relation to the viscoelastic behavior of porcine skin is presented, along with a series of empirical studies testing the performance of the model. The model assumes that the skin behaves as a semi-infinite, locally isotropic, viscoelastic halfspace. While the assumption of a semi-infinite body is violated, this violation does not appear to have a significant impact on the performance of the model based on the empirical studies. 1-Hz surface waves in the skin propagate primarily as Rayleigh waves with a wavelength and velocity of approximately 3 m and 3.0 …

Exact Synthesis Of 3-Qubit Quantum Circuits From Non-Binary Quantum Gates Using Multiple-Valued Logic And Group Theory, Guowu Yang, William N. N. Hung, Xiaoyu Song, Marek Perkowski Jan 2004

Exact Synthesis Of 3-Qubit Quantum Circuits From Non-Binary Quantum Gates Using Multiple-Valued Logic And Group Theory, Guowu Yang, William N. N. Hung, Xiaoyu Song, Marek Perkowski

Electrical and Computer Engineering Faculty Publications and Presentations

We propose an approach to optimally synthesize quantum circuits from non-permutative quantum gates such as Controlled-Square-Root–of-Not (i.e. Controlled-V). Our approach reduces the synthesis problem to multiple-valued optimization and uses group theory. We devise a novel technique that transforms the quantum logic synthesis problem from a multi-valued constrained optimization problem to a permutable representation. The transformation enables us to utilize group theory to exploit the symmetric properties of the synthesis problem. Assuming a cost of one for each two-qubit gate, we found all reversible circuits with quantum costs of 4, 5, 6, etc, and give another algorithm to realize these reversible …

Logic Synthesis For Regular Fabric Realized In Quantum Dot Cellular Automata, Marek Perkowski, Alan Mishchenko Jan 2004

Logic Synthesis For Regular Fabric Realized In Quantum Dot Cellular Automata, Marek Perkowski, Alan Mishchenko

Electrical and Computer Engineering Faculty Publications and Presentations

Quantum Dot Cellular Automata are one of the most prospective nano-technologies to build digital circuits. Because of the requirements of only 2 layer wiring and noise avoidance, realizing the circuit in a regular fabrics is even more important for this technology than for classical technologies. In this paper, we propose a regular layout geometry called 3x3 lattice. The main difference of this geometry compared to the known 2x2 lattices is that it allows the cofactors on a level to propagate to three rather than two nodes on the lower level. This gives additional freedom to synthesize compact functional representations. We …

Synthesis Of Reversible Circuits From A Subset Of Muthukrishnan-Stroud Quantum Realizable Multi-Valued Gates, Marek Perkowski, Nicholas Denler, Bruce Yen, Pawel Kerntopf Jan 2004

Synthesis Of Reversible Circuits From A Subset Of Muthukrishnan-Stroud Quantum Realizable Multi-Valued Gates, Marek Perkowski, Nicholas Denler, Bruce Yen, Pawel Kerntopf

Electrical and Computer Engineering Faculty Publications and Presentations

We present a new type of quantum realizable reversible cascade. Next we present a new algorithm to synthesize arbitrary single-output ternary functions using these reversible cascades. The cascades use “Generalized Multi-Valued Gates” introduced here, which extend the concept of Generalized Ternary Gates introduced previously. While there were 216 GTGs, a total of 12 ternary gates of the new type are sufficient to realize arbitrary ternary functions. (The count can be further reduced to 5 gates, three 2-qubit and two 1-qubit). Such gates are realizable in quantum ion trap devices. For some functions, the algorithm requires fewer gates than results previously …
