    Oral history interview with Willis Daniel

    Transcript, 48 pp.Daniel focuses on the origin and growth of the National Machine Accountants Association (NMAA), later the Data Processing Management Association (DPMA). He describes how the changes in business data processing in the 1940s and 1950s led to the creation of NMAA in an effort to pool knowledge and resources as well as increase the professionalism of the emerging position of data processing manager. Daniel discusses the development of the associations organizational structure as it grew. In this context, he describes the start of chapters, NMAA's merger with the National Tabulating Management Society, and the growth of NMAA's support structure. Daniel reviews the accomplishments of NMAA and DPMA presidents and notes the contributions, especially in education, of NMAA and DPMA to the development of data processing management.Daniel, Willis.

    Report on Meteorological Research March 1, 1935 (m-1)

    The object of the report was to elucidate in detail the various features of the research program in meteorology being carried on at the Daniel Guggenheim Airship Institute in Akron, Ohio. Mr. L. J. Fangman, of the U.S. Weather Bureau, was collaborating with the author in carrying out work such as a study of autographic records of the various meteorological elements during frontal passages with a view to the possible prediction of the intensity of the accompanying disturbance as it may affect the operation of aircraft and a study of atmospheric gustiness with a view to finding the dependence between frequency end amplitude of velocity fluctuations and the vertical temperature and velocity gradients

    Comparison Of Scattered Energy Using Point Scatterers Versus Full 3D Finite Difference Modeling

    We present results of 3D numerical modeling using a series of simple point scatterers to create synthetic seismic shot records collected over regular, discrete, vertical fracture systems. The background medium is taken to be constant velocity. The model contains a series of point scatterers delineating the top tip and bottom tip of each vertical fracture. We use these results to gain an understanding of some of the features seen in full 3D elastic modeling of vertical fractures. We compare our results to those of Willis et al (2003) and Willis et al (2004) for their 5 layer model with 50m spacing between discrete, vertical fractures. Our modeling shows that a series of back scattered events with both positive and negative moveouts are observed when the shot record is oriented normal to the direction of fracturing. When the shot record is both located in the middle of the fractured zone and is oriented normal to the direction of fracturing, a complicated series of beating is observed in the back scattered energy. When the shot record is oriented parallel to the fracturing, ringing wavetrains are observed which moveouts similar to reflections from many horizontal layers. The point scattering models are, in general, very consistent with the full 3D elastic modeling results.Eni S.p.A. (Firm)United States.

    (Fourth) Report on Meteorological Activities at the DGAI (8-1-36)(Weather Bureau Copy)

    This report is on the investigations of frontal phenomena at the Daniel Guggenheim Airship Institute in Akron, Ohio from January 1, 1935 through August 1, 1936. The investigation was carried out with the cooperation of the U.S. Bureau of Aeronautics, the U.S. Weather Bureau, the California Institute of Technology, and the Guggenheim Airship Institute. Mr. R.C. Robinson of the Weather Bureau cooperated with the author in carrying out the investigation. The object of the investigation was to determine the intensity of the atmospheric disturbances (i.e. rapidity of wind shift and gustiness) accompanying the passage of cold fronts, along with a study of the characteristics of the air masses involved and other features which might affect the intensity of the disturbance. The report treated thirty cold fronts which passed the station during 1935 to 1936
