By initially presenting FFI and its operations analysis (OA) activity, this paper illustrates the use of OA computing at FFI in three ways, in defense analysis, Simula, and various analyses of air defense. The paper focuses on methods, particularly the use of discrete event simulation. Most examples are from 1978–1995, and Simula’s role is highlighted.

An analysis of notifications of tuberculosis in the City of Birmingham during the three-year period 1960-62 related to the population data from the Census of 1961 showed important differences between the notification rates of groups defined by their place of birth, and also differences in the age distributions of notification rates between these groups (Springett, 1964). A survey of notificatio...

OBJECTIVES This report presents trends in the mean age of mothers giving birth for the United States for the last three decades. Data are presented by live-birth order, race, Hispanic origin, and State of residence of the mother. METHODS Descriptive tabulations and graphs of the trends in the mean age of mother are discussed. RESULTS The mean age of mother has increased steadily in the Unit...

An epidemiological study was conducted in the city of Rome and the incidence of malignant melanoma was determined retrospectively for the years 1970-9. All patients had legal residence in Rome and a histological diagnosis of melanoma during that period; only cases of malignant melanoma of the skin (ICD 172, 8th revision) were considered. A total of 17 public and 82 private hospitals were involv...

The 1970 British Birth Cohort Study (BCS70) is an ongoing, multidisciplinary, longitudinal study. It takes as its subjects all those currently living in England, Scotland, and Wales who were born in a single week of 1970. To date there have been seven sweeps of the study, including the original birth survey. BCS70 began as the British Births Survey, when data was collected about the births and ...

Note that the footnotes have been changed slightly (their numbering and, in one case, the general form). This is because I have not been able to figure out how to use ’1*’, ’2*’, and ’3*’ as footnote references in TeX. (In the German there is a difference between footnotes by Bernays and footnotes by a later editor; the former have ’1’ and ’2’, the latter ’1*’, ’2*’, and ’3*’ as labels.) Note i...

The recent rulings which grant University administrations the power to review and censor the appropriations of student governments on campuses in New York pose an intolerable threat to student autonomy. The procedures that have been established by the Executive Committee of the Board of Trustees allow University presidents to impose their own political beliefs and biases on the entire system of...

von Neumann [2], Codd [4], and others who attempt to achieve various computational goals using minimal (for example, fewest states) primitive modules. Input and output are all done from a single machine, which, while no theoretical limitation because of the lumping of finite-state machines, is a further dissimilarity between the author's arrays and practical parallel-processing computing scheme...

A retrospective review was conducted of all esthesioneuroblastoma cases treated at UCLA Medical Center from 1970 through 1990. Patients were staged according to the staging systems of Kadish, et al., Biller, et al., and a new staging system proposed by the authors. Of 26 patients treated, 74% were alive at 5 years and 60% were alive at 10 years. Combined treatment with surgery and radiation is ...
