Software development tools: A bibliography, appendix C.
A bibliography containing approximately 200 citations on tools which help software developers perform some development task (such as text manipulation, testing, etc.), and which would not necessarily be found as part of a computing facility is given. The bibliography comes from a relatively random sampling of the literature and is not complete. But it is indicative of the nature and range of tools currently being prepared or currently available
Software development environments: A bibliography, appendix G
A bibliography containing approximately 100 citations on software development environments is given. The bibliography comes from a relatively random sampling of the literature and is not complete
Software development environments: Present and future, appendix D
Computerized environments which facilitate the development of appropriately functioning software systems are discussed. Their current status is reviewed and several trends exhibited by their history are identified. A number of principles, some at (slight) variance with the historical trends, are suggested and it is argued that observance of these principles is critical to achieving truly effective and efficient software development support environments
An assessment of DREAM, appendix E
The design realization, evaluation and modelling (DREAM) system is evaluated. A short history of the DREAM research project is given as well as the significant characteristics of DREAM as a development environment. The design notation which is the basis for the DREAM system is reviewed, and the development tools envisioned as part of DREAM are discussed. Insights into development environments and their production are presented and used to make suggestions for future work in the area of development environments
Software development environment, appendix F
The current status in the area of software development environments is assessed. The purposes of environments, the types of environments, the constituents of an environment, the issue of environment integration, and the problems which must be solved in preparing an environment are discussed. Some general maxims to guide near-term future work are proposed
Measurements of surface-pressure and wake-flow fluctuations in the flow field of a whitcomb supercritical airfoil
Measurements of surface pressure and wake flow fluctuations were made as part of a transonic wind tunnel investigation into the nature of a supercritical airfoil flow field. Emphasis was on a range of high subsonic Mach numbers and moderate lift coefficients corresponding to the development of drag divergence and buffeting. Fluctuation data were analyzed statistically for intensity, frequency content, and spatial coherence. Variations in these parameters were correlated with changes in the mean airfoil flow field
Flight software requirements and design support system
The desirability and feasibility of computer-augmented support for the pre-implementation activities occurring during the development of flight control software was investigated. The specific topics to be investigated were the capabilities to be included in a pre-implementation support system for flight control software system development, and the specification of a preliminary design for such a system. Further, the pre-implementation support system was to be characterized and specified under the constraints that it: (1) support both description and assessment of flight control software requirements definitions and design specification; (2) account for known software description and assessment techniques; (3) be compatible with existing and planned NASA flight control software development support system; and (4) does not impose, but may encourage, specific development technologies. An overview of the results is given
How Devolved is Too Devolved?: A Comparative Analysis Examining the Allocation of Power Between State and Local Government Through the Lens of the Confederate Monument Controversy
At various critical junctures in our nation’s history, lawmakers have struggled to strike the proper balance between centralization and delegation of authority. Recently, the debate over whether to remove Confederate monuments has again brought to the fore this centuries-old struggle. Beginning in 2000, state legislatures throughout the South enacted statutes primarily designed to protect Civil War monuments, which in the South predominantly pay tribute to the Confederate cause. Recent attempts by Southern localities to remove Confederate monuments have revealed the inadequacy of these recently-enacted statutes. Virtually every state legislature that has successfully passed a statute on the topic has produced a law that entirely prohibits removal of Confederate monuments by localities, save certain extreme exceptions. Conversely, in those states where no statute addresses the issue of removal, the decision is left entirely to individual localities, as state officials have no legal authority on the matter. Both arrangements fail to provide for the proper allocation of authority between state and local government. In failing to do so, the respective governmental responses fall short in realizing the attendant policy benefits of proper allocation of authority. The statutory responses of two states, Georgia and Kentucky, provide a useful lens through which to analyze the effects of improper allocation of authority and, on the other hand, to consider the potential benefits of the proper allocation of authority. In light of these considerations, this Note suggests a model statutory approach that provides a process for both protection and removal of Confederate monuments and, by striking the proper balance, allows for meaningful political engagement at both the state and local level
Flight measured downwash of the QSRA
Several reports have been written on the performance of the Quiet Short-Haul Research Aircraft, which shows the advantages of upper-surface blowing or the propulsive-lift wing as it applies to lift, maneuverability, and short takeoff and landing. This high lift generation at low speeds results in substantial downwash, especially in the low-aft fuselage tail position. The high T-tail of the Quiet Short-Haul Research Aircraft minimizes the undesirable downwash effects from the propulsive-lift wing. Queries from Department of Defense agencies and industry for quantitative values prompted a series of flight-measured downwash tests at the high T-tail and the low aft fuselage position. The results are presented in a summarized format, showing downwash, Delta epsilon/Delta a, for both locations. As would be expected, downwash increases for increased power and USB flap settings. The downwash is greater in the low aft-fuselage position as compared to the high T-tail area
