The Multi-Dimensional Nature of Wind Shear Investigations
The impact of air carrier accidents has lead to investigations into the wind shear phenomenon. This report includes such topics as wind shear characterization, aircraft pilot performance in shear conditions, terminology and language development, wind shear forecasting, ground and flight wind shear displays, wind shear data collection and dissemination, and pilot factors associated with wind shear encounters. Some areas which show promise for short term solutions to the wind shear hazards includes: (1) improved gust front warning through ground based sensors; (2) greater pilot awareness of wind shear through improved training; and (3) airborne displays based on groundspeed/airspeed comparisons
Highly linear, sensitive analog-to-digital converter
Analog-to-digital converter converts 10 volt full scale input signal into 13 bit digital output. Advantages include high sensitivity, linearity, low quantitizing error, high resistance to mechanical shock and vibration loads, and temporary data storage capabilities

Apollo experience report: Guidance and control systems - Digital autopilot design development
The development of the Apollo digital autopilots (the primary attitude control systems that were used for all phases of the lunar landing mission) is summarized. This report includes design requirements, design constraints, and design philosophy. The development-process functions and the essential information flow paths are identified. Specific problem areas that existed during the development are included. A discussion is also presented on the benefits inherent in mechanizing attitude-controller logic and dynamic compensation in a digital computer
Variety, globalization, and social efficiency
This paper puts recent work on the benefits of variety into the context of an exact quantitative analysis of the Dixit-Stiglitz-Krugman model of monopolistic competition. We show that the gains from international trade are almost completely determined by the increase in variety and not economies of scale, and that the social efficiency question is quantitatively insignificant. These results follow from allowing the number of varieties to affect the elasticity of demand facing each firm. Most applications of the DSK model abstract from variety’s effect by assuming that the elasticity of demand facing each firm equals the elasticity of substitution in a CES utility function, thus fixing the output of each firm by the resulting markup over marginal costs. Finally, we develop a precise expression for real per capita income with any number of sectors. ; Also issued as Globalization and Monetary Policy Institute Working Paper No. 15
