Real-time flight test analysis and display techniques for the X-29A aircraft

The X-29A advanced technology demonstrator flight envelope expansion program and the subsequent flight research phase gave impetus to the development of several innovative real-time analysis and display techniques. These new techniques produced significant improvements in flight test productivity, flight research capabilities, and flight safety. These techniques include real-time measurement and display of in-flight structural loads, dynamic structural mode frequency and damping, flight control system dynamic stability and control response, aeroperformance drag polars, and aircraft specific excess power. Several of these analysis techniques also provided for direct comparisons of flight-measured results with analytical predictions. The aeroperformance technique was made possible by the concurrent development of a new simplified in-flight net thrust computation method. To achieve these levels of on-line flight test analysis, integration of ground and airborne systems was required. The capability of NASA Ames Research Center, Dryden Flight Research Facility's Western Aeronautical Test Range was a key factor in enabling implementation of these methods

Growth and population dynamics of crayfish Paranephrops planifrons in streams within native forest and pastoral land uses

Population dynamics of crayfish (Paranephrops planifrons White) in streams draining native forest and pastoral catchments, Waikato, New Zealand, were investigated from September 1996 to July 1998. Crayfish densities were generally greater in native forest streams because of high recruitment over summer, but varied greatly between streams in both land uses. Peak densities in summer were 9 crayfish m-2 in native forest and 6 crayfish m-2 in pasture streams, but peak biomass in summer was much greater in pasture streams. Mark-recapture data showed that crayfish, particularly juveniles, in pasture streams grew faster than in native forest streams, through both greater moult frequency and larger moult increments. Females reached reproductive size at c. 20 mm orbit-carapace length (OCL) after their first year in pasture streams, but after 2 years in native forest streams. Annual degree days >10°C appeared to explain the differences in the timing of life cycles. Estimates of annual crayfish production (range = 0.8-3.4 g dry weight m-2 year-1) were similar in both land uses, and P/B ratios were between 0.95 and 1.2. Despite deforestation and conversion to pasture, crayfish in these Waikato hill-country streams have maintained similar levels of annual production to those in native forest streams, although juvenile growth rates have increased and longevity has decreased

Give My Regards to the Book

This project is an analysis of the construction of American Musical Theatre. The research for this project has been drawn from direct quotes and writings from Musical Theatre writers, scores and scripts, and from historical books. Reading of these sources reveal principles of Musical Theatre writing which the authors use and the audience expects. This project analyzes how the book, lyrics, and music to a show are written and demonstrates that the writing of Musical Theatre has developed its own unique craft which is grounded in the book

What Are the Hills Really Alive With?: Spectacle versus Narrative Driven Musical Theatre

American Musical Theatre is known for its entertaining qualities, but what holds the audience’s attention to stick around for the second act? Is it the dance numbers, the fancy lighting, and the spectacular numbers or is it the story and the characters? Musical theatre always uses a combination of the two elements, but one of two tends to drive an individual musical forward and engage the audience\u27s attention. The conflict of emphasizing spectacle or narrative can bee seen initially at Musical Theatre\u27s conception all the way down to recent shows written by Webber and Sondheim. Spectacle can be understood as the dances, musical numbers, and effects in a show that are used to dazzle the audience. Narrative, on the other hand, is the use of storyline and character development to engage the audience. Through its history, musical theatre has combined these two forces and each show places a higher emphasis on one or the other
