Skylab ATM/S-056 X-ray event analyzer observations versus solar flare activity: An event compilation
An event compilation is presented which correlates ATM/S-056 X-ray event analyzer solar observations with solar flare activity. Approximately 1,070 h of pulse height analyzed X-ray proportional counter data were obtained with the X-ray event analyzer during Skylab. During its operation, 449 flares (including 343 flare peaks) were observed. Seventy events of peak X-ray emission or = Cl were simultaneously observed by ground based telescopes, SOLRAD 9 and/or Vela, and the X-ray event analyzer. These events were observed from preflare through flare rise to peak and through flare decline.

Parallel compilation: A design and its application to SIMULA 67
A design is presented for a parallel compilation facility for the SIMULA 67 programming language. The proposed facility allows top-down, bottom-up, or parallel development and integration of program modules. An evaluation of the proposal and a discussion of its applicability to other languages are then given.

Compiler validates units and dimensions
Software added to compiler for automated test system for Space Shuttle decreases computer run errors by providing offline validation of engineering units used system command programs. Validation procedures are general, though originally written for GOAL, a free-form language that accepts "English-like" statements, and may be adapted to other programming languages.

A compilation and analysis of helicopter handling qualities data. Volume 2: Data analysis
A compilation and an analysis of helicopter handling qualities data are presented. Multiloop manual control methods are used to analyze the descriptive data, stability derivatives, and transfer functions for a six degrees of freedom, quasi static model. A compensatory loop structure is applied to coupled longitudinal, lateral and directional equations in such a way that key handling qualities features are examined directly.

The surface exposure /maturity/ of lunar soils - Some concepts and I sub s/FeO compilation
Surface exposure (or, equivalently, maturity) indices of lunar soils are a measure of residence time of soil in the upper one millimeter of the regolith. Several concepts concerning the use of and terminology associated with maturity indices are discussed. For reasons which include its generally-applicable nature and large data base, the ferromagnetic resonance (FMR) surface exposure (maturity) index I sub s/FeO (the ratio of the value of the intensity in arbitrary units of the FMR resonance at g equal to about 2.1 to the FeO concentration) is particularly suitable and useful. A compilation of values of I sub s/FeO for 164 Apollo surface and trench soils and six Luna 24 core soils is given.
