A general problem in science and control engineering is that of identifying a system on the basis of observations. This series of studies will show how to view this as a nonlinear multipoint boundary-value problem that can be resolved numerically using the method of quasilinearization. The memorandum hunts for hidden periodicities in data and provides an alternative to the classical periodogram analysis. 10 pp. (See also RM-4266, RM-4332.)

Our mission to help improve policy and decisionmaking through research and analysis is enabled through our core values of quality and objectivity and our unwavering commitment to the highest level of integrity and ethical behavior. To help ensure our research and analysis are rigorous, objective, and nonpartisan, we subject our research publications to a robust and exacting quality-assurance process; avoid both the appearance and reality of financial and other conflicts of interest through staff training, project screening, and a policy of mandatory disclosure; and pursue transparency in our research engagements through our commitment to the open publication of our research findings and recommendations, disclosure of the source of funding of published research, and policies to ensure intellectual independence.
