The Use Of Border Collies In Avian And Wildlife Control Programs, Nicholas B. Carter
The Use Of Border Collies In Avian And Wildlife Control Programs, Nicholas B. Carter
Wildlife Damage Management Conference
Airports attract large numbers of wildlife primarily because they offer immense tracts of foraging and nesting habitats free from the threat of predation. Border collies can serve as an effective means of wildlife control in these environments by introducing a predator into the ecosystem. Many wildlife dispersal methods seek to imitate predators or the effect of predators and become increasingly ineffective as wildlife habituate to the stimuli. However, border collies are true predators, representing an actual, not perceived, threat to wildlife thereby eliminating the problems of habituation. Six airports and military bases have initiated use of border collies at their …

Determination Of Wax Concentration In Sunflower-Seed Oil, Silvana Martini, M.C. Anon
Nutrition, Dietetics, and Food Sciences Faculty Publications
Isothermal crystallization of waxes was studied by using an optical setup. The induction time of crystallization was assessed as a function of wax concentration. The relationship was found to be a decreasing exponential curve. The wax content of some of the solutions prepared in the laboratory was determined by calculating the crystallization induction time. The values obtained were compared to those from different methods (cold test, microscopic, and turbidimetric methods). The results obtained with the optical setup method are similar to those obtained with other methods for concentrations greater than 100 ppm. An analysis of variance test was used to …

Western Rangeland Noxious Weeds: Collecting, Sharing And Using Information, U.S. Department Of Interior, U.S. Department Of Agriculture, Riley Memorial Foundation
All U.S. Government Documents (Utah Regional Depository)
Western rangeland weeds such as yellow starthistle, leafy spurge, Canada thistle and Russian knapweed are causing tremendous losses to agricultural industries, including both crop and livestock production, and to environmental resources on private lands. Concurrently, many public lands managed by federal agencies are being steadily invaded. As a result, these lands held in the public trust are experiencing reductions in commodity yields, recreational opportunities, biodiversity and ecosystem function.

Autonomous Operations Experiments For The Distributed Emerald Nanosatellite Mission , Christopher Kitts, Michael Swartwout
Autonomous Operations Experiments For The Distributed Emerald Nanosatellite Mission , Christopher Kitts, Michael Swartwout
Small Satellite Conference
Distributed space systems are often cited as a means of enabling vast performance increases ranging from enhanced mission capabilities to increased system flexibility. Achieving this vision, however, will require radical advances in the automated control of these multi-satellite systems. To explore this challenge, Santa Clara University and Stanford University have initiated development of a simple, low cost, two-satellite mission known as Emerald. The Emerald mission includes several experiments involving the autonomous operation of distributed space systems. First, “low-level” inter-satellite navigation techniques will be explored. Second, “high-level” multi-satellite health and command management functions will be demonstrated. Due to operational considerations and …
Real-Time Attitude And Orbit Control System Of A Small Leo Satellite With Parallel-Processing Approach In A Ground Station, Roger Johnson, Sanjay Jayaram, Lei Sun, Chan Ho Ham
Real-Time Attitude And Orbit Control System Of A Small Leo Satellite With Parallel-Processing Approach In A Ground Station, Roger Johnson, Sanjay Jayaram, Lei Sun, Chan Ho Ham
Small Satellite Conference
A Real-time Attitude and Orbit Control System (AOCS) using a parallel processing approach will be implemented using a Satellite Ground Control Station (SGCS). With this approach, the satellite will collect platform (attitude reference) and payload measurements (at 1Hz) over several orbits and down-link to the SGCS (at 5 KHz) where the real-time filtering, fault detection, diagnosis and corrective (if needed) control is generated. The control commands are up-linked to the satellite before losing telemetry lock. A substantial reduction in on-board computation can provide a cheaper and a higher reliable AOCS. In the proposed scheme, an advanced real-time estimation and control …

Aeroastro’S X-Band Transponder – Meeting The Communication Needs Of Tomorrow’S Small Spacecraft , Eric Aamot, Ray Zenick, Kimberly Kohlhepp
Small Satellite Conference
This paper will discuss a number of technologies and design philosophies leveraged from commercial industry that AeroAstro has applied to the development of a new spacecraft communications subsystem. Although there has been a recent push toward reducing spacecraft mass and cost, there is no commercially available communications equipment that will significantly contribute to that reduction. While spacecraft mass has dropped more than an order of magnitude in the past ten years, radios have not followed this trend. AeroAstro is developing a highly integrated, power-efficient, low operating voltage X-Band telemetry transponder for small satellite applications. This design leverages emerging technology from …

Effects Of A Distributed Computing Architecture On The Emerald Nanosatellite Development Process , Julie Townsend, Bryan Palmintier, Eric Allison
Small Satellite Conference
Building satellites with greater capabilities on shorter timelines requires changes in development approach. Relative to previous satellite projects in Stanford’s Space Systems Development Laboratory (SSDL), the Emerald Nanosatellite system is highly complex. Its mission requires numerous experiments and relatively sophisticated subsystem capabilities. To develop this system on a short two-year timeline required a new development approach to simplify system integration. As a result, the Emerald development team adopted a modular distributed computing architecture. While this decision imposed many changes on Emerald’s design process, the benefits of the distributed architecture for system integration and testing justified its selection. This approach has …

Economic Sanctions: Their Ineffectiveness At Attaining Their Stated Foreign Policy Goals With Specific Reference To The Cuban Case, Harold Lee Ingram
Economic Sanctions: Their Ineffectiveness At Attaining Their Stated Foreign Policy Goals With Specific Reference To The Cuban Case, Harold Lee Ingram
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
International economic sanctions are not singularly modem phenomena. In ancient Greece, Pericles of Athens enacted the Megerian Decree in 432 BC in response to hostile acts taken against it by neighboring Megera. Later, during the American Revolutionary War, Thomas Jefferson encouraged the use of sanctions as an effective tool of coercive foreign policy to be used against the colonists' enemies. Since then, following the historical precedence of economic acts like the Megerian Decree, economic sanctions have continued to be used as tools of coercive diplomatic policy. For example, following World War I, President Woodrow Wilson encouraged the use of economic …
