Operationally-relevant test lengths : a decision-analysis approach.

This thesis approaches the question of How much testing is enough? by formulating a model for the combat situation in which the weapon (e.g., missile) will be used. Methods of Bayesian statistics are employed to allow the decision maker to benefit from prior information gained in the testing of similar systems by forecasting the operational gain from acceptance. A Microsoft Excel V7.0 spreadsheet serves as the user interface, and Visual Basic for Applications, Excel's built in macro-language, is the language used to produce the source code. The methodology accommodates two different tactical usages for the missile: a single shot, or a salvo of two shots. The missile might be acceptable if used in the two-shot salvo mode, but not in the single shot mode, and this would imply a greater cost per mission. In the end the missile might not be judged cost effective as compared to a competitive system. If the model proposed is (or can become) adequate much can be calculated/estimated before any operational tests are made. This could assist in economizing on operational testinghttp://archive.org/details/operationallyrel00gormApproved for public release; distribution is unlimited

A correlation of formulas for the flow of fluids in pipes

At present there exist two quite distinct fields in fluid flow in pipes, the one in water supply and the other in the petroleum industry. It is the purpose of this paper to discuss the various pipeline flow formulas as used in both fields and to correlate the exponential type formula which is much used in practice with the Nikuradse curves obtained in the laboratory --A Brief Historical Review, page 5

Ryan Indemnity in Maritime Property Damage Cases: What of Proportionate Fault?

In 1956 the Supreme Court in Ryan Stevedoring Co. v. Pan-Atlantic Steamship Corp. implied a warranty of workman-like performance in stevedoring contracts. The stevedore\u27s breach of this warranty entitled the shipowner to full indemnity for damages paid by the shipowner to injured longshoremen. This Article discusses the origin and development of the Ryan warranty and Ryan indemnity, focusing on post-Ryan statutory and decisional developments. The author advocates the application of principles of comparative negligence in maritime property damage cases
