Special purpose computer provides programmable digital filter for sampled-data control systems
Generalized digital filter is a special purpose computer. The term digital filter is an algorithm which accepts an input sequence of numbers and transforms it into an output number sequence. The organization of the computer, the logical design and synthesis, and experimentaion with the computer in two sampled data control systems is discussed.

Aeronautical engineering, a special bibliography, September 1971 (supplement 10)
This supplement to Aeronautical Engineering-A Special Bibliography (NASA SP-7037) lists 413 reports, journal articles, and other documents originally announced in September 1971 in Scientific and Technical Aerospace Reports (STAR) or in International Aerospace Abstracts (IAA). The coverage includes documents on the engineering and theoretical aspects of design, construction, evaluation, testing, operation, and performance of aircraft (including aircraft engines) and associated components, equipment, and systems. It also includes research and development in aerodynamics, aeronautics, and ground support equipment for aeronautical vehicles. Each entry in the bibliography consists of a standard bibliographic citation accompanied by an abstract. The listing of the entries is arranged in two major sections, IAA Entries and STAR Entries in that order. The citations and abstracts are reproduced exactly as they appeared originally in IAA or STAR, including the original accession numbers from the respective announcement journals.

Special projects of the geographic applications program
Alternative uses were investigated for the Mississippi Test Facility since the phaseout of Saturn 5 engine testing. Using the facility for collecting remotely sensed data is suggested for regional studies. The capabilities of various remote sensing devices to detect, identify, monitor, or determine effects of environmental pollution are summarized. Which pollutants could be monitored from spacecraft, high and low altitude aircraft, and ground based platforms are determined. Examples of special processing and enhancement and analysis techniques used in connection with remote sensing data are provided.

Specialized testing and evaluation of space-suit materials
The selection of nonmetallic materials used in the Apollo space suits is discussed. The specialized test program to determine the flammability of selected space suit materials is described. Emphasis is placed on the equipment used to test and qualify the space suit materials and subassemblies for operation in the deep space environment.
