The Subsystemless Satellite - A New Design Paradigm For The Next Generation Of Small Satellites, Bill Jackson, Jim Campbell
The Subsystemless Satellite - A New Design Paradigm For The Next Generation Of Small Satellites, Bill Jackson, Jim Campbell
Small Satellite Conference
Traditional satellite design techniques appear to break down for very small spacecraft weighing less than about 50 lbs. In order to break this barrier, it is necessary to implement a new satellite design paradigm - that of the "subsystemless" satellite. In such a satellite, the design process emphasizes the identification and specification of functional requirements per the usual systems engineering procedures. However, the identified requirements are never allocated to subsystems. Instead, the various spacecraft functions are implemented directly without regard to traditional spacecraft subsystem boundaries. The result is a highly integrated design which is compact, lightweight, and highly efficient. This …

Miniature Sensor Technology Integration (Msti) -3 Pointing Error Analysis And Compensation, Howard Taylor, Lesley Rahman, Todd Probert
Small Satellite Conference
MSTI-3, an advanced technology demonstration satellite, was launched on May 16, 1996, to collect data in the short wave infrared (SWIR) and medium wave infrared (MWIR) bands. MSTI-3's mission was to survey the Earth: collecting data to support analysis of ground features, such as terrain and bodies of water; and atmospheric features, such as clouds and aurora. In April 1997, MSTI-3 analysts computed a pointing offset of approximately 50 miles. This paper summarizes the detailed fault analysis implemented by the operations team, including steps taken to isolate the cause of the pointing error to the payload mirror gimbal roll encoder …

Physics & Astronomy
In January 1997 a large fleet of NASA and US military satellites provided the most complete observations to date of the changes in >2 MeV electrons during a geomagnetic storm. Observations at geosynchronous orbit revealed a somewhat unusual two-peaked enhancement in relativistic electron fluxes [ Reeves et al., 1998]. In the heart of the radiation belts at L ≈ 4, however, there was a single enhancement followed by a gradual decay. Radial profiles from the POLAR and GPS satellites revealed three distinct phases. (1) In the acceleration phase electron fluxes increased simultaneously at L ≈ 4–6. (2) During the …

Diversity And Dominant Species Of Ground Beetle Assemblages (Coleoptera: Carabidae) In Crop Rotation And Chemical Input Systems For The Northern Great Plains, Michael M. Ellsbury, Janine E. Powell, Frank Forcella, W. David Woodson, Sharon A. Clay, Walter E. Riedell
Agronomy, Horticulture and Plant Science Faculty Publications
Dominant carabid species present in crops and crop rotation sequences commonly used in the northern Great Plains were assessed as an initial step toward the management of carabids as natural control agents. Ground beetle populations were determined by pitfall trapping in 4 crop rotation treatments maintained under high, managed, and low levels of chemical fertilizer and pesticide inputs. Diversity and species richness among crops, rotations, and input levels were compared using 3 indices—the Shannon-Weaver Index, relative diversity, and the Hierarchical Richness Index (HRI). Four carabid species, Cyclotrachelus altemans (Casey), Poecilvs lucublandus Say, Harpalns pensylvanicus (DeGeer), and Bembidion quadrimaculatum L., comprising …
Attractors For Non-Compact Semigroups Via Energy Equations, Ioana Moise, Ricardo Rosa, Xiaoming Wang
Attractors For Non-Compact Semigroups Via Energy Equations, Ioana Moise, Ricardo Rosa, Xiaoming Wang
Mathematics and Statistics Faculty Research & Creative Works
The energy-equation approach used to prove the existence of the global attractor by establishing the so-called asymptotic compactness property of the semigroup is considered, and a general formulation that can handle a number of weakly damped hyperbolic equations and parabolic equations on either bounded or unbounded spatial domains is presented. as examples, three specific and physically relevant problems are considered, namely the flows of a second-grade fluid, the flows of a Newtonian fluid in an infinite channel past an obstacle, and a weakly damped, forced Korteweg-de Vries equation on the whole line.

Applications Of Secondary Electron Energy- And Angular-Distributions To Spacecraft Charging, Neal Nickles, R. E. Davies
Applications Of Secondary Electron Energy- And Angular-Distributions To Spacecraft Charging, Neal Nickles, R. E. Davies
All Physics Faculty Presentations
Secondary electron (SE) emission from spacecraft surfaces as a result of energetic electron bombardment is a key process in the electrical charging of spacecraft. It has been suggested that incorporating more complete knowledge of the energy- and angular-distributions of secondary electrons is necessary to fully model how SE emission and spacecraft charging are affected by re-adsorption of low energy electrons in the presence of charge-induced electrostatic fields and ambient magnetic fields in the spacecraft environment. We present data for such energy- and angular-distributions from sputtered, polycrystalline gold surfaces. The data are compared to empirical SE emission models and found to …

Track Structure Model For Radial Distributions Of Electron Spectra And Event Spectra From High-Energy Ions, F. A. Cucinotta, Robert Katz, J. W. Wilson
Track Structure Model For Radial Distributions Of Electron Spectra And Event Spectra From High-Energy Ions, F. A. Cucinotta, Robert Katz, J. W. Wilson
Robert Katz Publications
An analytic method is described for evaluating the average radial electron spectrum and the radial and total frequency-event spectrum for high-energy ions. For high-energy ions, indirect events make important contributions to frequency-event spectra. The method used for evaluating indirect events is to fold the radial electron spectrum with measured frequency-event spectrum for photons or electrons. The contribution from direct events is treated using a spatially restricted linear energy transfer (LET). We find that high-energy heavy ions have a significantly reduced frequency-averaged lineal energy (YF) compared to LET, while relativistic protons have a significantly increased YF and dose-averaged lineal energy (YD) …

In summer 1995, in collaboration with the deep multi-channel seismic profiling project around the island of Taiwan, anonshore-offshore wide-angle deep seismic profiling experiment was conducted in Taiwan. The results are expected to provide the first complete seismic images of the deep crustal structure for a better understanding of the Taiwan orogeny and subduction-collision system. The experiment consists of three profiles, one along each of the central and southern cross-island highways and another on the south-link highway of the island. For the first two lines, 35 three-component portable seismographs were deployed along each of the 116 and 135 km-long profiles onshore, …

Vulnerability And Use Of Ground And Surface Waters In The Southern Mississippi Valley Region, H. Don Scott
Arkansas Water Resources Center Technical Reports
There is a concern in the Southern Mississippi River Valley of the United States over non-point source pollution of ground and surface waters resulting from activities associated with agricultural production. This agriculturally intensive region consists of two major land resource areas (MLRAs): Southern Mississippi Valley Silty Uplands (MLRA 134) and the Southern Mississippi Valley Alluvium (MLRA 131). Both MLRAs have level to undulating and rolling topography, relatively fertile soils and a climate particularly conducive for row crop production.
