Topological simplifications for mechanical vibration analysis
Simmons, James Leon
MetadataShow full item record
A theoretical method for representing the physical characteristics of a portion of a mechanical piping system in terms of a stiffness matrix involving only those joints at which the sub-system is connected into the overall system is presented herein. The use of this method in reducing the size of the matrices that are needed for finding the normal vibration frequencies of a piping system is discussed, and an outline for a digital computer program to use this method is presented.

A Method for Identification, Representation, and Assessment of Complex System Pathologies in Acquisition Programs Keating, Charles B.; Katina, Polinpapilinho F.; Joiner, Keith F.; Bradley, Joseph M.; Jaradat, Raed M. (Monterey, California. Naval Postgraduate School, 2018-04-30); SYM-AM-18-104Acquisition programs continue to struggle with increasing complexity. High degrees of emergence, interconnectedness, and uncertainty are the norm rather than exception. The purpose of this research is to explore extension ...
Analyzing the Effects of Source Selection Method, Acquisition Type, and Service Component on Acquisition Outcomes Landale, Karen A. F.; Rendon, Rene G. (Monterey, California. Naval Postgraduate School, 2017-03); SYM-AM-17-043For years, one of the most hotly contested debates in contracting and acquisition has been the choice of source selection method and the contract-related consequences of that choice. While policy memos encourage contracting ...
