Technology requirements for advanced earth orbital transportation systems. Volume 2: Summary report

The results of efforts to identify the technology requirements for advanced earth orbital transportation systems are reported. Topics discussed include: (1) design and definition of performance potential of vehicle systems, (2) advanced technology assessment, and (3) extended performance. It is concluded that the horizontal take-off concept is the most feasible system considered

Testing and Analysis of Paired, Inflated HIAD Tori

The Hypersonic Inflatable Aerodynamic Decelerator is a stack of concentric, inflated rings (tori) being developed by NASA for landing spacecraft. This research will build on work previously done at UMaine to understand the structural behavior of the HIAD by examining the response of two tori paired together. A test fixture previously used to test single tori was analyzed and modified to withstand the estimated forces from testing paired tori. Two single tori of different sizes were tested separately on the fixture at various inflation pressures. The tests consisted of displacing the tori equally at 16 discrete points using cables attached to individual actuators. The actuators were synchronized using a modified version of the control code used previously. Noncontact photogrammetry data, as well as the forces in each cable, were collected throughout each test. The photogrammetry data will also be used to determine the displaced shapes of the specimens. The testing was repeated with a paired specimen consisting of two tori of the same sizes as tested previously. A finite element model of the paired tori was developed and verified using data collected from the physical tests

Dedication to Dean Edward Settle Godfrey, III

It is impossible to fully describe the impact that Dean Godfrey had (and continues to have) on the legal community in Maine, on the University of Maine School of Law, and on the Maine Law Review. This Article provides a sampling of the lives he touched and the contributions he made to the law through his writings. On February 5, 2005, the Maine legal community celebrated the life and work of the Honorable Edward S. Godfrey, III. In attendance were his family members; past and present faculty, staff, and students of the University of Maine School of Law, the law school he founded in 1962; his colleagues from the Maine Supreme Judicial Court; his law clerks; and members of the legal community. Representatives from every facet of his life spoke that day. Wendy Godfrey-Dean, his niece, spoke of his loving ways with his family. Former Chief Justice of the Maine Supreme Judicial Court, the Honorable Vincent L. McKusick, spoke of the Dean\u27s forty-three years of service to the Maine legal community and of his tenure on the Law Court. Arlyn Weeks spoke of her work with him as a law clerk and of the lasting friendship that developed as a result. Gerald Petruccelli spoke of the early days of the Law School and the challenges the Dean overcame. Former Chief Justice of the Maine Supreme Judicial Court, the Honorable Daniel E. Wathen, spoke of him as his mentor and teacher while studying at the University of Maine School of Law and working with him on the Maine Law Review. There were many moving tributes delivered that day in honor of Dean Godfrey, a veritable giant in the Maine legal community. These tributes are included, in their entirety, as Part II of this Article

A turbojet-boosted two-stage-to-orbit space transportation system design study

The concept to use twin turbo-powered boosters for acceleration to supersonic staging speed followed by an all rocket powered orbiter stage was proposed. A follow-on design study was then made of the concept with the performance objective of placing a 29,483 Kg payload into a .2.6 X 195.3 km orbit. The study was performed in terms of analysis and trade studies, conceptual design, utility and economic analysis, and technology assessment. Design features of the final configuration included: strakes and area rule for improved take off and low transonic drag, variable area inlets, exits and turbine, and low profile fixed landing gear for turbojet booster stage. The payload required an estimated GLOW of 1,270,000 kg for injection in orbit. Each twin booster required afterburning turbojet engines each with a static sea level thrust rating of 444,800 N. Life cycle costs for this concept were comparable to a SSTO/SLED concept except for increased development cost due to the turbojet engine propulsion system

Validating a GPS collar-based method to estimate parturition events and calving locations for two barren-ground caribou herds

Thesis (M.S.) University of Alaska Fairbanks, 2019In remote landscapes, it is difficult and expensive to document animal behaviors such as location and timing of parturition. When aerial surveys cannot be conducted as a result of weather, personnel or fiscal constraints, analyses of GPS collar movement data may provide an alternate way to estimate parturition rates and calving ground locations. I validated two methods (population-based method and individual-based method), developed to detect calving events of sedentary woodland caribou, on multiple years of data for two different migratory barren-ground caribou herds in Alaska, the Porcupine and Fortymile herds. I compared model estimates of population parturition rates, individual calving events, calving locations and calving dates to estimates from aerial survey data for both herds. For the Porcupine herd we also compared model estimates of annual calving ground sizes and locations of concentrated calving area centroids to those found with aerial survey. More years of data would be required for additional statistical power but for both the Porcupine and Fortymile herds, we found no significant difference between the population-based and individual-based method in: 1) individual classification rate accuracy (0.85 vs. 0.88, respectively; t = -7, P = 0.09, df = 1 and 0.85 vs. 0.83, respectively; t = 0.46, P = 0.69, df = 2) or 2) annual average distance from aerial survey calving locations (8.9 vs. 7.8 km, respectively; t = 0.16, P = 0.90, and 5.2 vs. 3.7 km, respectively; t = 1.03, P = 0.20). Median date of calving was estimated within 0-3 days of that estimated by aerial survey for both methods. Population parturition rate estimates from aerial survey, the population-based and individual-based methods were not significantly different for the PCH or FCH (0.91, 0.88 and 0.95, respectively; F = 0.67, P = 0.60, df = 2, and 0.83, 0.83 and 0.96, respectively; F = 3.85, P = 0.12, df = 2). Ultimately, more years of data would be required to support or reject the lack of significant differences between methods that we observed.U.S. Fish and Wildlife Service, Alaska Department of Fish and GameChapter 1: Porcupine Caribou Herd - Validating a GPS-based method for estimating parturition events and calving locations -- Chapter 2: Fortymile Caribou Herd - Validating a GPS-based method for estimating parturition events and calving locations -- General conclusion
