Surrey Satellite Technology Ltd is reviewing the ability of small satellite platforms to add complementary capability to the presently defined Global Monitoring for Environment and Security (GMES) space segment, allowing the broadest possible set of user requirements to be met. A set of user-focused services has been compared with the instruments and measurement capabilities defined for the currently proposed Sentinel platforms. This comparison illustrated the challenges of using a few satellites, as in the current Sentinel scenario, carrying multiple instruments to serve the diverse needs of land, coastal, oceanic, emergency response and emergency management users.


Multipoint In-Situ Radiation And Plasma Sensing System (Mirpss), Nestor Voronka, Robert Hoyt, Sven Bilén Aug 2007

Multipoint In-Situ Radiation And Plasma Sensing System (Mirpss), Nestor Voronka, Robert Hoyt, Sven Bilén

Small Satellite Conference

To ensure the safety of human explorers as well as the health and productivity of robotic systems both in Earth orbit and beyond, it is important to understand and predict the space plasma and radiation-belt particle dynamics in the Earth’s ionosphere and magnetosphere. Increased scientific understanding of how the Earth’s ionosphere and magnetosphere respond to changes due to solar variability will enhance our ability to provide forecasts and “nowcasts” of space weather. To this end, TUI and Penn State are developing a nanosatellite mission concept that utilizes a constellation of CubeSat-class satellites containing in situ radiation, plasma, and magnetic field …

Application Of The Themis Bus To New Missions, Michael Cully, Warren Chen, Kevin Brenneman, Gregory Delory

Small Satellite Conference

It is recognized that small satellites can complement the services provided by existing larger satellites, providing cost effective solutions to military missions, communications systems, remote sensing applications, satellite rapidresponse, science and technology demonstrator missions. However, today’s small satellites are largely confined to low Earth orbit where they perform remote sensing missions, conduct science operations, and serve as technology test beds. Future small satellite missions will include interplanetary missions, space-weather mapping as well as space exploration and robotic probes.

Smallsats To The Moon: Providing The ‘Picks And Shovels For The 21st Century’S Greatest Exploration Endeavour’ , Adam Baker, Andy Phipps, Philip Davies, Xavier Alabart, Martin Sweeting

Small Satellite Conference

Small spacecraft have an enviable history of changing the economics of space. Space development and exploration has historically been costly, and going beyond Earth orbit even more so. However the cost-performance balance of small spacecraft has increased to the point where new commercial business cases using space infrastructure can be enabled. This paper outlines SSTL’s approach to low cost missions, and its validity to exploration, in particular the Moon. The political environment for supporting space missions, particularly exploration in the United Kingdom is covered, including study activities building the case for a national exploration programme and their fit to strategic …


Faster, Smaller, Cheaper: Exploiting The Imminent Low-Cost Launch Era , G.A. Finney, Kevin Spradley, Mark Fowler, Michael Gulley Aug 2007

Faster, Smaller, Cheaper: Exploiting The Imminent Low-Cost Launch Era , G.A. Finney, Kevin Spradley, Mark Fowler, Michael Gulley

Small Satellite Conference

The 1990s initiated the era of “Faster, Better, Cheaper” for small spacecraft, and met with mixed success. However, even under the best of circumstances, “Faster, Better, Cheaper” faces the hurdle of high launch costs. In programs with typical launch costs of $20 - 50M or more, spacecraft capabilities are pushed to the limit in order to extract maximum value from the overall system. This drive for high performance results in complex systems, which require significant engineering to address relatively minor changes. However, new launch vehicles offer the potential to reduce launch costs to under $10M and will change the economics …

The Role Of Geographic Information Systems Inwildlife Epidemiology: Models Of Chronic Wasting Disease In Colorado Mule Deer, Matthew L. Farnsworth, Jennifer A. Hoeting, N. Thompson Hobbs, Mary M. Conner, Kenneth P. Burnham, Lisa L. Wolfe, Elizabeth S. Williams, David M. Theobald, Michael W. Miller

Wildland Resources Faculty Publications

The authors present findings from two landscape epidemiology studies of chronic wasting disease (CWD) in northern Colorado mule deer (Odocoileus hemionus). First, the effects of human land use on disease prevalence were explored by formulating a set of models estimating CWD prevalence in relation to differences in human land use, sex and geographic location. Prevalence was higher in developed areas and among male deer suggesting that anthropogenic influences (changes in land use), differences in exposure risk between sexes and landscape-scaled heterogeneity are associated with CWD prevalence. The second study focused on identifying scales of mule deer movement and mixing that …

Psychology Faculty Publications

Acceptance and commitment therapy (ACT) has previously been shown to alter stigmatizing attitudes and to be relatively useful for psychologically inflexible participants. The present study is the first to bring those two findings together by comparing ACT to an education intervention for reducing stigma toward people with psychological disorders, and examining whether results differ for psychologically inflexible versus flexible individuals. A sample of college students (N=95) was randomly assigned to a 21/2 h ACT or educational workshop. Measures were taken before and after the workshop and at a 1-month follow-up. ACT reduced mental health stigma …

Does Removing Coyotes For Livestock Protection Benefit Free-Ranging Ungulates?, Justin L. Harrington, Michael R. Conover Jun 2007

Does Removing Coyotes For Livestock Protection Benefit Free-Ranging Ungulates?, Justin L. Harrington, Michael R. Conover

Wildland Resources Faculty Publications

We studied the effects of coyote (Canis latrans) control for livestock protection on native ungulates during 2003 and 2004 on 7 sites in Utah and Colorado, USA, totaling over 1,900 km2. We found no relationships between coyote control variables and offspring/female deer ratios. However, control effort (no. of hr spent aerial gunning for coyotes) and success (no. of coyotes taken) were positively correlated with numbers of mule deer (Odocoileus hemionus) and pronghorn (Antilocapra americana) observed per kilometer of transect. Our results suggest that coyote control for livestock protection may increase densities of mule deer and pronghorn in areas where it …


Implications Of Research On Expertise For Curriculum And Pedagogy, David F. Feldon Jun 2007

Implications Of Research On Expertise For Curriculum And Pedagogy, David F. Feldon

Instructional Technology and Learning Sciences Faculty Publications

Instruction on problem solving in particular domains typically relies on explanations from experts about their strategies. However, research indicates that such self-reports often are incomplete or inaccurate (e.g., Chao & Salvendy, 1994; Cooke & Breedin, 1994). This article evaluates research on experts’ cognition, the accuracy of experts’ self-reports, and the efficacy of instruction based on experts’ self-reports. Analysis of this evidence indicates that experts’ free recall of strategies introduces errors and omissions into instructional materials that hinder student success. In contrast, when experts engage in structured knowledge elicitation techniques (e.g., cognitive task analysis), the resultant instruction is more effective. Based …

Anatomic Dead Space Cannot Be Predicted By Body Weight, Lara M. Brewer, Joseph A. Orr May 2007

Anatomic Dead Space Cannot Be Predicted By Body Weight, Lara M. Brewer, Joseph A. Orr

Utah Space Grant Consortium

Anatomic, airway, or tracheal, dead space is the part of the tidal volume that does not participate in gas exchange. Knowledge of the size of the dead space is important for proper mechanical ventilation, especially if small tidal volumes are used. Respiratory and medical textbooks state that anatomic dead space can be estimated from the patient’s body weight. Specifically, these references suggest dead space can be predicted using a relationship of one milliliter per pound of body weight. Using a volumetric capnography monitor that incorporates on-airway flow and CO2 monitoring (NICO2, Respironics, Wallingford CT), anatomic dead space can be automatically …

A Historic Perspective: The Response Of Breeding Passerines To Rangeland Alteration In Rich County, Utah, Lindsay J. Brown May 2007

A Historic Perspective: The Response Of Breeding Passerines To Rangeland Alteration In Rich County, Utah, Lindsay J. Brown

Biology

Shrub-dominated ecosystems on private lands are important rangeland resources through much of the western U.S., including Rich County, Utah. Because of its important role in livestock production, this shrubsteppe ecosystem has been exposed to a variety of sagebrush removal methods. Little is known about the relative effects of chemical, mechanical, or burn treatments on breeding passerine communities. Furthermore, most studies address only short-term effects. We studied breeding passerine communities and vegetation on 17 untreated sites and 49 range sites treated between 1962 and 2004 to examine the effects of treatment type and treatment age. The sagebrush treatments produced considerable changes …
