    I would especially like to thank the following people for their help in my research into the Brownsville Missouri Pacific passenger station. Without their help, I would have had something, but probably not much of something. These people provided me with many things, such as photos, information, contacts, ideas, opinions, enthusiasm, and encouragement. I am indebted to them for their assistance. My hat is off to you guys.https://scholarworks.utrgv.edu/mopacbrownsville/1043/thumbnail.jp

    There were many more photographs, post cards, etc., that I used to determine measurements from, however, some of those, including many of the most important ones, were still copyrighted, and so could not be included in this collection. That is unfortunate, but the included files do give an indication of the method I used. On the file include here, the measurements notated on the photo are not necessarily the final measurements I settled on in all cases. Some of the photos I was not able to include have the more accurate determined measurements notated on them.

    Missouri Pacific Brownsville Depot Writings - History revision 2

    Get PDF
    Typed document. The railroad passenger station in Brownsville, Texas that saw service through the Depression, World War II, and the twilight years of rail travel in the United States was a unique structure in many ways. For many of Brownsville’s residents, this building was the prime example of the beautiful architecture which abounds throughout the city. What brought about the need for this station and its construction is an interesting story, and begins with the history of the railroads in south Texas. © 2017 David N.

    Application of bifurcation methods for the prediction of low-speed aircraft ground performance

    Get PDF
    The design of aircraft for ground maneuvers is an essential part in satisfying the demanding requirements of the aircraft operators. Extensive analysis is done to ensure that a new civil aircraft type will adhere to these requirements, for which the nonlinear nature of the problem generally adds to the complexity of such calculations. Small perturbations in velocity, steering angle, or brake application may lead to significant differences in the final turn widths that can be achieved. Here, the U-turn maneuver is analyzed in detail, with a comparison between the two ways in which this maneuver is conducted. A comparison is also made between existing turn-width prediction methods that consist mainly of geometric methods and simulations and a proposed new method that uses dynamical systems theory. Some assumptions are made with regard to the transient behavior, for which it is shown that these assumptions are conservative when an upper bound is chosen for the transient distance. Furthermore, we demonstrate that the results from the dynamical systems analysis are sufficiently close to the results from simulations to be used as a valuable design tool. Overall, dynamical systems methods provide an order-of-magnitude increase in analysis speed and capability for the prediction of turn widths on the ground when compared with simulations.
