On Approximating Linear Array Factors

This Memorandum considers least-mean-square comparison of directivity patterns of line sources having different illumination distributions.

A Product Theorem for Hilbert Transforms

A presentation of a mathematical theorem for finding the Hilbert transform of a product of functions in a simplified fashion under certain conditions.

Engineering Model Atmosphere of Mars.

A technical model of the Martian atmosphere that gives extreme upper and lower probable limits between which must fall the atmospheric parameters of pressure, temperature, and density up to 150-km altitude over middle and low latitudes. Other parame...

A Summary of the Supersonic Pressure Drag of Bodies of Revolution

A number of approximate theories for supersonic and hypersonic flow over bodies of revolution at zero angle of attack are appraised.

A Systems Engineering Approach to Reliability

Reliability approached as a problem of designing reliable systems using existing and, therefore, none too reliable components.

Some mathematical aspects of optimization problems in engineering.

An application of the functional-equation technique of dynamic programming as a guide in the formulation and in the analytical and numerical treatment of chemical-engineering problems that involve multistage decision processes. Deterministic, stochas...

General Impact Theory of Pressure Broadening

A theory of pressure broadening is developed which treats the perturbers quantum mechanically.

Problem of Overlapping Lines in the Theory of Pressure Broadening

The theory of pressure broadening is re-examined, in order to include the possibility of overlapping lines.

The Digital Computer: Where Does It Go from Here?

This paper, presented in 1954 to the Los Angeles Section of the Institute of Radio Engineers, examines the early field and trends of digital computing.

Schlieren Techniques for the Quantitative Study of Gas Mixing

A simplified discussion of the fundamental principles underlying the schlieren method.

Climb path for least elapsed time.

An examination of an engineering method which determines the path a jet-powered airplane must follow to achieve a specified speed and altitude in the least elapsed time. An analysis of the suitability of the method and the conditions under which it b...
