Long Memory Inflationary Dynamics: The Case Of Brazil, Mark E. Jensen, Valderio A. Reisen, Francisco Cribari-Neto

Faculty Publications

It has been argued by several authors that the inflationary dynamics in Brazil follow a unit root process, thus displaying some inertia. Indeed, Cati, et al. (Journal of Applied Econometrics, 1999) have found that the inflationary dynamics in Brazil are nearly fully inertial. We estimate the fractional differencing parameter using an ARFIMA specification for the inflation rate in that country and our results suggest that the inflationary dynamics are better modeled by a long memory process than by a unit root mechanism, thus implying that there is no inertia in inflation, contrary to what has been found by other researchers. …

Theory, Design, And Fabrication Of Diffractive Grating Coupler For Slab Waveguide, Kevin Randolph Harper

Theses and Dissertations

This thesis presents the theory design and fabrication of a diffractive grating coupler. The first part of the design process is to choose the period of the grating coupler based on the desired coupling angle. The second part of the design process is to choose the geometry of the grating that gives maximum coupling efficiency based on rigorous analyses.

The diffraction gratings are fabricated by recording the interference between two waves in photoresist. The waveguide is fabricated from silicon nitride that is deposited by chemical vapor deposition. The diffraction grating recording assembly is described along with the grating coupler fabrication …

Trust Negotiation For Authentication And Authorization In Healthcare Information Systems, Charles D. Knutson, Kent E. Seamons, Tore L. Sundelin, David K. Vawdrey

Faculty Publications

The expanding availability of health information in an electronic format is strategic for industry-wide efforts to improve the quality and reduce the cnst of health care. The implementation of electronic medical record systems has been hindered by inadequate security provisions. This paper describes the use of frust negotiation as a framework for providing authentication and access control services in healthcare information systems. nust negotiation enables two parties with no pre-existing relationship to establish the trust necessary to perform sensitive transactions via the mutual disclosure of attributes contained within digital credentials. An extension of this system, surrogate irusf negoikiion is introduced …

A Descriptive Performance Model Of Small, Low Cost, Diskless Beowulf Clusters, Curtis R. Nielson

Theses and Dissertations

Commodity supercomputing clusters known as Beowulf clusters, have become a low cost alternative to traditional supercomputers. Beowulf clusters combine inexpensive computers and specialized software to achieve supercomputing power. The processing nodes in a diskless Beowulf cluster do not have a local hard disk unlike the nodes in most commodity clusters. Research has provided performance information for diskless clusters built with expensive, high performance equipment. Beowulf clusters use commodity off-the-shell hardware, and little information is available about their performance. This research includes the construction of several diskless Beowulf clusters. Using the NAS Parallel Benchmarks, the performance of these clusters was measured. …

Prehistoric Timberline Adaptations In The Eastern Uinta Mountains, Utah, Michelle Knoll

Theses and Dissertations

Excavations at a high altitude archaeological site (3350 m) in the eastern Uinta Mountains, Utah, uncovered at least three ephemeral brush structures. These temporary timberline dwellings are the highest structures excavated in Utah to date. The periods of occupation range from the early Fremont period to the post-contact era. It is believed that the Fremont occupations are logistical in nature, possibly representing male hunting parties. Logistical camps imply a departure from, and return to, a residential camp. Ethnographic studies show that most residential camps are located within proximity to culinary plants to facilitate collection by women. In the Uinta Mountains, …

Evaluating Tmr Techniques In The Presence Of Single Event Upsets, Paul S. Graham, Nathaniel Rollins, Michael J. Wirthlin, Michael P. Caffrey

Faculty Publications

Sponsorship: Los Alamos National Labs (LA-UR-03-7525). Field programmable gate arrays (FPGAs) are sensitive to radiation-induced single event upsets (SEUs) within the configuration memory. Triple modular redundancy (TMR) is a technique commonly used to mitigate against design failures caused by SEUs. This paper evaluates the effectiveness and cost of TMR on two different counter designs in the presence of SEUs. The evaluation measures the reliability, area cost, and speed of different TMR styles. The tests show that when feedback TMR is used with triplicated clocks, it is possible to have counter design which is insensitive to any single configuration upset.

A Narrative Approach To Exploring Responsible Involvement Of Fathers With Their Special-Needs Children, David C. Dollahite

Faculty Publications

This chapter briefly summarizes the main findings from research employing narrative methodologies on fathers of children with special needs conducted by me and my students (Brotherson & Dollahite, 1997; Dollahite, 2003; Dollahite, Marks, & Brotherson, 1998; Dollahite, Marks, & Olson, 2002; Marks & Dollahite, 2001; Olson, Dollahite, & White, 2002). This research is consistent with recent emphasis on narrative methods in the social sciences generally (Dollahite, Hawkins, & Brotherson, 1996; Josselson & Lieblich, 1993; McAdams, 1993; Riessman, 1993; Sarbin, 1986) and with recent narrative studies of fathers of special-needs children (Brotherson, 1995) and fathers and religion, (Latshaw, 1998; Marshall, Olsen, …

Dynamic Sociometry In Particle Swarm Optimization, Mark Richards, Dan A. Ventura

Faculty Publications

The performance of Particle Swarm Optimization is greatly affected by the size and sociometry of the swarm. This research proposes a dynamic sociometry, which is shown to be more effective on some problems than the standard star and ring sociometries. The performance of various combinations of swarm size and sociometry on six different test functions is qualitatively analyzed.

The New Economy Is Dead, Long Live The Information Economy, Phillip J. Bryson

Faculty Publications

The arrival of the 2001-2003 recession caused many to suppose that the so-called "New Economy" was now defunct. This article addresses a number of related issues, including the question of the durability and viability of business cycles in the face of the technological developments of the information age. It asks what went wrong with the New Economy and examines its characteristics as well as its remaining possibilities and prospects for the future. Finally, it considers the spread of the Information Economy to Europe, especially to Germany, the country that one might expect to be the leading European player, but which …

Modular Verification Of Timed Circuits Using Automatic Abstraction, Eric G. Mercer, Chris Myers, Hao Zheng

Faculty Publications

The major barrier that prevents the application of formal verification to large designs is state explosion. This paper presents a new approach for verification of timed circuits using automatic abstraction. This approach partitions the design into modules, each with constrained complexity. Before verification is applied to each individual module, irrelevant information to the behavior of the selected module is abstracted away. This approach converts a verification problem with big exponential complexity to a set of subproblems, each with small exponential complexity. Experimental results are promising in that they indicate that our approach has the potential of completing much faster while …

Autonomous Vehicle Technologies For Small Fixed Wing Uavs, Derek B. Kingston, Randal Beard, Timothy Mclain, Michael Larsen, Wei Ren

Faculty Publications

Autonomous unmanned air vehicle flight control systems require robust path generation to account for terrain obstructions, weather, and moving threats such as radar, jammers, and unfriendly aircraft. In this paper, we outline a feasible, hierarchal approach for real-time motion planning of small autonomous fixed-wing UAVs. The approach divides the trajectory generation into four tasks: waypoint path planning, dynamic trajectory smoothing, trajectory tracking, and low-level autopilot compensation. The waypoint path planner determines the vehicle's route without regard for the dynamic constraints of the vehicle. This results in a significant reduction in the path search space, enabling the generation of complicated paths …

Institutional Issues In The Implementation Of An International Student Exchange Program, Mary E. Duffy, Suzette Farmer, Patricia K. Ravert, Liisa Huittinen

Faculty Publications

The article discusses institutional issues related to the development and implementation of an undergraduate student exchange program in nursing. A consortium of four universities in the United States and six nursing schools in three European countries developed an exchange program to teach a common community health module. Thirty-one students from the United States and 30 students from Europe participated in this program, which was by the U.S. Department of Education and the European Union. The project commenced with a 3-week meeting of faculty and students to design the 8-week exchange program and cultural preparation module. This article describes institutional issues …

Plant Community Patterns In Unburned And Burned Blackbrush (Coleogne Ramosissima Torr.) Shrublands In The Mojave Desert, Matthew L. Brooks, John R. Matchett

Western North American Naturalist

The blackbrush vegetation type is dominated by Coleogyne ramossisima, which is thought to preclude the coexistence of many other plant species. Fire can remove blackbrush cover and possibly increase plant species richness and evenness. Fire also may increase the frequency and cover of alien annual grasses, thereby intensifying landscape flammability. We tested these predictions in unburned and burned (6–14 years postfire) blackbrush at 3 sites spanning the range of this vegetation type in the Mojave Desert.

Species richness in unburned blackbrush was similar to published values for vegetation types in western North America, bur richness varied significantly among the …

Distributional Information On Birds From Egg Sets Collected By Henry Rogers Durkee In 1870 In Southwestern Wyoming, Douglas B. Mcnair, James P. Dean

Western North American Naturalist

Henry Rogers Durkee collected 74 egg sets of 27 avian species in 1870 at Gilmer, Uinta County, in southwestern Wyoming. Despite the paucity of documented breeding evidence from this region during the late 19th and early 20th centuries, his material at the Smithsonian Institution was generally overlooked and has never been critically examined. Durkee's egg sets included 5 species (Sandhill Crane, Grus candensis; Northern Rough-winged Swallow, Stelgidoteryx serripennis; Grasshopper Sparrow, Ammodramus savannarum; Fox Sparrow, Passerella iliaca; Cassin's Finch, Carpodacus cassinii) whose breeding distribution was then poorly known, 25 to more than 70 years before nests …

Insect-Mediated Pollination In Slickspot Peppergrass, Lepidium Papilliferum L. (Brassicaceae), And Its Implications For Population Viability, Ian C. Robertson, Danielle Klemash

Western North American Naturalist

Field experiments on the pollination biology of slickspot peppergrass, Lepidium papilliferum L. (Brassicaceae), a rare species endemic to microsites in sagebrush-steppe habitat in southwestern Idaho, were conducted at 2 sites from May to July 2001. Site KB contained over 10,000 plants, whereas site WG contained less than 150 plants. Insect exclusion experiments revealed that seed production in L. papilliferum is dependent on insect-mediated pollination; median percent seed set dropped from 70% to 2% when insects were excluded from flowers. A total of 25 insect families from 5 orders visited L. papilliferum flowers: 24 families at KB and 11 families at …

Northern Saw-Whet Owl (Aegolius Acadicus) Migration In The Pacific Northwest, Graham G. Frye, Richard P. Gerhardt

Western North American Naturalist

Northern Saw-whet Owls (Aegolius acadicus) were captured in north central Oregon, USA, during autumn 1999 and 2000 as a pilot study on migration in the Pacific states. We captured 70 individuals, with annual capture rates comparable to those reported for larger studies in the eastern and Midwestern U.S. We investigated differential capture by time of night, time of season, and age. No results were significant due to small samples and brief duration of the study, although some results tended toward significance (P < 0.10). Here we provide a descriptive account of our observations of Northern Saw-whet Owl migration in north central Oregon, the first such study to be presented for the Pacific states.

Recurrence Of Mexican Long-Tongued Bats (Choeronycteris Mexicana) At Historical Sites In Arizona And New Mexico, Paul M. Cryan, Michael A. Bogan

Western North American Naturalist

The Mexican long-tongued bat (Choeronycteris mexicana) is a nectar-eating species that seasonally inhabits the southwestern United States. Since 1906, fewer than 1500 individuals of C. mexicana have been documented throughout the range of the species. We conducted a field survey in Arizona and New Mexico during summer 1999 to check historically occupied areas for recurrence of C. mexicana. We observed C. mexicana occupying a majority (75%, n = 18) of visited sites. Multiple individuals were observed at many sites, including young-of-year. Choeronycteris mexicana roosted in lighted areas close to entrances within mine adits, abandoned buildings, wide rock …

Dispersal Of Sagebrush-Steppe Seeds By The Western Harvester Ant (Pogonomyrmex Occidentalis), John F. Mull

Western North American Naturalist

Like many seed-harvesting ants, the western harvester ant (Pogonomyrmex occidentalis) can act as both a predator and a seed disperser. Dispersal results when seeds are dropped en route to the nest, are left in nest granaries when colonies die or are abandoned, or are removed from granaries and discarded in nest middens. This study examined the density and species identity of seeds discarded in harvester ant nest middens and compared them with those found in nearby soils. Nineteen species of seeds were recovered from middens, compared with 13 species in 5-m reference areas and 9 species in adjacent …
