Coherent Design Of Uninhabited Aerial Vehicle Operations And Control Stations, Amy R. Pritchett, Luis Nicolas Gonzalez Castro, Daniel Pierre Jacques Bruneau Jan 2007

Coherent Design Of Uninhabited Aerial Vehicle Operations And Control Stations, Amy R. Pritchett, Luis Nicolas Gonzalez Castro, Daniel Pierre Jacques Bruneau

International Symposium on Aviation Psychology - 2007

Designing for UAV systems presents novel challenges, both in terms of selecting and presenting adequate information for effective teleoperation, and in creating operational procedures and ground control station interfaces that are robust to a range of UAV platforms and missions. We propose that a vital design objective is establishing coherence between these three features (function, procedures, and ground control station interfaces). Specifically, principles of coherent design are applied to the design of operational procedures and ground control stations (GCS) for uninhabited aerial vehicles (UAVs). Creating a coherent set of operating procedures, automatic functions and operators requires a systematic design approach …

The Chicken, The Egg, The Workspace Analysis, And The Ecological Interface., M.M. (Rene) Van Paassen, Matthijs H.J. Amelink, Clark Borst, Stijn B.J. Van Dam, Max Mulder

International Symposium on Aviation Psychology - 2007

The first applications of the design of operator interfaces with CognitiveWorkspace Analysis and Ecological Interface Design were in the field of power plants and process control. These applications are similar to the DURESS microworld, for which the first EID design was made. The workspace analysis for these domains can then be similar to the analysis elaborated for DURESS. At the Faculty of Aerospace Engineering of the Delft University of Technology, in several projects now EID has been applied to a different work domain, namely vehicle control. These projects have focused on, among others, conflict avoidance in aircraft and ships, terrain …

Mandarin Chinese: An Annotated Bibliography Of Self- Study Materials, Duncan Alford

International Journal of Legal Information

The People’s Republic of China is currently the seventh largest economy in the world and is projected to be the largest economy by 2050. Commensurate with its growing economic power, the PRC is using its political power more frequently on the world stage. As a result of these changes, interest in China and its legal system is growing among attorneys and academics. International law librarians similarly are seeing more researchers interested in China, its laws and economy. The principal language of China, Mandarin Chinese, is considered a difficult language to learn. The Foreign Service Institute has rated Mandarin as “exceptionally …

Contrasting Roles Of Neural Firing Rate And Local Field Potentials In Human Memory, A. Ekstrom, Indre Viskontas, M. Kahana, J. Jacobs, K. Upchurch, S. Bookheimer, I. Fried Jan 2007

Contrasting Roles Of Neural Firing Rate And Local Field Potentials In Human Memory, A. Ekstrom, Indre Viskontas, M. Kahana, J. Jacobs, K. Upchurch, S. Bookheimer, I. Fried

Psychology

Recording the activity of neurons is a mainstay of animal memory research, while human recordings are generally limited to the activity of large ensembles of cells. The relationship between ensemble activity and neural firing rate during declarative memory processes, however, remains unclear. We recorded neurons and local field potentials (LFPs) simultaneously from the same sites in the human hippocampus and entorhinal cortex (ERC) in patients with implanted intracranial electrodes during a virtual taxi-driver task that also included a memory retrieval component. Neurons increased their firing rate in response to specific passengers or landmarks both during navigation and retrieval. Although we …

The Visual Image Of Chemistry: Perspectives From The History Of Art And Science, Joachim Schummer, Tami I. Spector Jan 2007

The Visual Image Of Chemistry: Perspectives From The History Of Art And Science, Joachim Schummer, Tami I. Spector

Chemistry Faculty Publications

In this paper we investigate the most important visual stereotypes of chemistry as they occur in current portraits of chemists, depictions of chemical plants, and images of chemical glassware and apparatus. By studying the historical origin and development of these stereotypes within the broader context of the history of art and science, and by applying aesthetic and cultural theories, we explore what these images implicitly communicate about the chemical profession to the public. We conclude that chemists, along with commercial artists, have unknowingly created a visual image of chemistry that frequently conveys negative historical associations, ranging from imposture to kitsch. …

From Morphology To Neural Information: The Electric Sense Of The Skate, Marcelo Camperi, Timothy C. Tricas, Brandon R. Brown Jan 2007

From Morphology To Neural Information: The Electric Sense Of The Skate, Marcelo Camperi, Timothy C. Tricas, Brandon R. Brown

Physics and Astronomy

Morphology typically enhances the fidelity of sensory systems. Sharks, skates, and rays have a well-developed electrosense that presents strikingly unique morphologies. Here, we model the dynamics of the peripheral electrosensory system of the skate, a dorsally flattened batoid, moving near an electric dipole source (e.g., a prey organism). We compute the coincident electric signals that develop across an array of the skate's electrosensors, using electrodynamics married to precise morphological measurements of sensor location, infrastructure, and vector projection. Our results demonstrate that skate morphology enhances electrosensory information. Not only could the skate locate prey using a simple population vector algorithm, but …

Impacts Of Predators On Northern Bobwhites In The Southeast, John P. Carroll, Susan N. Ellis-Felege, William E. Palmer Jan 2007

Impacts Of Predators On Northern Bobwhites In The Southeast, John P. Carroll, Susan N. Ellis-Felege, William E. Palmer

School of Natural Resources: Faculty Publications

The northern bobwhite quail (Colinus virginianus) is an important game bird that is intensively managed for hunting recreation in the southeastern United States. Despite interest regionwide, populations have been declining for much of the last 40 years (Brennan 1999). Population declines in the Southeast have occurred as a result of widespread habitat loss associated with land-use changes (Brennan 1999). These land-use changes include both conversion from agricultural to forest landscapes and changes in forest management practices, which result in dense forest canopies that shade required ground vegetation (Brennan 1999, Rollins and Carroll 2001). In addition, low-quality habitats may …

Nutrient Cycling In Forage Production Systems, David A. Wedin, Michael P. Russelle Jan 2007

Nutrient Cycling In Forage Production Systems, David A. Wedin, Michael P. Russelle

School of Natural Resources: Faculty Publications

In most forage production systems, the nutrients needed for plant growth are provided by microbially mediated breakdown and release of plant-available mineral nutrients from dead plant tissues, livestock excreta, soil organic matter, and geochemically bound mineral forms. Even in fertilized forage systems, determining appropriate fertilizer application rates requires a "systems" approach on the part of the manager (e.g., Di and Cameron, 2000; Rotz et al., 2002). Fertilizer additions are simply one input in the system of inputs, outputs, pools, and fluxes that characterize nutrient cycling in a particular ecosystem.

Approximating Variance Of Demographic Parameters Using The Delta Method: A Reference For Avian Biologists, Larkin A. Powell Jan 2007

Approximating Variance Of Demographic Parameters Using The Delta Method: A Reference For Avian Biologists, Larkin A. Powell

School of Natural Resources: Faculty Publications

Avian biologists routinely estimate sampling variance for parameter estimates such as daily nest survival, fecundity, annual survival, and density. However, many biologists are not certain of methods to derive sampling variance for parameters when survival rates change temporal scales. Similar methods are needed to obtain sampling variance when biologists combine parameter estimates to calculate an indirect demographic parameter, such as population growth rate. The delta method is a useful technique for approximating sampling variance when the desired demographic parameter is a function of at least one other demographic parameter. However, the delta method is rarely taught in most graduate-level biology …

High School Students' Perceptions Of A College Of Agricultural Sciences And Natural Resources, Susan Fritz, Dann E. Husmann, Duane Reese, Richard Stowell, Larkin A. Powell Jan 2007

High School Students' Perceptions Of A College Of Agricultural Sciences And Natural Resources, Susan Fritz, Dann E. Husmann, Duane Reese, Richard Stowell, Larkin A. Powell

School of Natural Resources: Faculty Publications

Declining enrollment in the College of Agricultural Sciences and Natural Resources fueled discussions about changing the name of the college as a means of reversing the trend. In spring 2005, a comprehensive study was launched to assess the perceptions of key college populations. This study relates to one of those four populationsresident, college-bound high school seniors. A survey developed by Kansas State University was a starting point for the development of a mailed survey to evaluate the college's image, the influence of the college's name, the level of awareness of program offerings and career opportunities, and to identify actionable changes. …

Bird Movement Predicts Buggy Creek Virus Infection In Insect Vectors, Charles R. Brown, Mary Bomberger Brown, Amy T. Moore, Nicholas Komar Jan 2007

Bird Movement Predicts Buggy Creek Virus Infection In Insect Vectors, Charles R. Brown, Mary Bomberger Brown, Amy T. Moore, Nicholas Komar

School of Natural Resources: Faculty Publications

Predicting the spatial foci of zoonotic diseases is a major challenge for epidemiologists and disease ecologists. Migratory birds are often thought to be responsible for introducing some aviozoonotic pathogens such as West Nile and avian influenza viruses to a local area, but most information on how bird movement correlates with virus prevalence is anecdotal or indirect. We report that the prevalence of Buggy Creek virus (BCRV) infection in cimicid swallow bugs (Oeciacus vicarius), the principal invertebrate vector for this virus, was directly associated with the likelihood of movement by cliff swallows (Petrochelidon pyrrhonota), an amplifying host …

Ecological Correlates Of Buggy Creek Virus Infection In Oeciacus Vicarius, Southwestern Nebraska, 2004, Amy T. Moore, Eric A. Edwards, Mary Bomberger Brown, Nicholas Komar, Charles R. Brown

School of Natural Resources: Faculty Publications

Buggy Creek virus (family Togaviridae, genus Alphavirus, BCRV) is an alphavirus within the western equine encephalitis virus complex whose primary vector is the swallow bug, Oeciacus vicarius Horvath (Hemiptera: Cimicidae), an ectoparasite of the colonially nesting cliff swallow, Petrochelidon pyrrhonota, that is also a frequent host for the virus.We investigated ecological correlates of BCRV infection in 100-bug pools at 14 different swallow colony sites in southwestern Nebraska from summer 2004, by using plaque assay on Vero cells to identify cytopathic virus and reverse transcription-polymerase chain reaction to identify noncytopathic viral RNA. We found 26.7% of swallow bug pools …

Managing Bovine Tuberculosis In White-Tailed Deer In Northwestern Minnesota: A 2007 Progress Report, Michelle Carstensen, David Pauly, Michael Doncarlos, Lou Cornicelli

Michigan Bovine Tuberculosis Bibliography and Database

Bovine tuberculosis (TB), first discovered in 2005, has now been found in 11 cattle operations in northwestern Minnesota. To date, all of the infected cattle herds have been depopulated and the Board of Animal Health (BAH) has continued an investigation of herds in the area as well as conducted a statewide surveillance effort. The strain has been identified as one that is consistent with bovine TB found in cattle in the southwestern United States and Mexico. In November 2007, the Minnesota Department of Natural Resources (MNDNR) conducted bovine TB surveillance of hunter-harvested white-tailed deer (Odocoileus virginianus) within a …
