The NASA role in major areas of human concern: Health care
Benefits derived from the civilian aeronautics and space effort are discussed in a statement whose focus is on the developments in health care which can be traced to specific NASA program elements. A summary is provided for each case where NASA has been involved in expanding the biomedical technical base, as well as where NASA has been directly instrumental in providing solutions in maintaining adequate health, and correcting health problems when they occur
Program for transfer research and impact studies
Research activities conducted under the program for Transfer Research and impact studies are reviewed. Programs include: Tech Brief - Technical Support Package (TSP) Program; transfer documentation; and technology transfer profiles. An analysis of user behavior patterns is made by studying questionnaires filled out by users of the Tech Brief - TSP program. The process of technology transfer is discussed in terms of improving its effectiveness
Program for transfer research and impact studies
Research activities conducted under the Program for Transfer Research and Impact Studies (TRIS) during 1972 included: (1) preparation of 10,196 TSP requests for TRIS application analysis; (2) interviews with over 500 individuals concerning the technical, economic, and social impacts of NASA-generated technology; (3) preparation of 38 new technology transfer example files and 101 new transfer cases; and (4) maintenance of a technology transfer library containing more than 2,900 titles. Six different modes of technology utilization are used to illustrate the pervasiveness of the transfer and diffusion of aerospace innovations. These modes also provide a basis for distinguishing the unique characteristics of the NASA Technology Utilization Program. An examination is reported of the ways in which NASA-generated technology is contributing to beneficial social change in five major areas of human concern: health, environment, safety, transportation, and communication
Incidence Hypergraphs: Box Products & the Laplacian
The box product and its associated box exponential are characterized for the
categories of quivers (directed graphs), multigraphs, set system hypergraphs,
and incidence hypergraphs. It is shown that only the quiver case of the box
exponential can be characterized via homs entirely within their own category.
An asymmetry in the incidence hypergraphic box product is rectified via an
incidence dual-closed generalization that effectively treats vertices and edges
as real and imaginary parts of a complex number, respectively. This new
hypergraphic box product is shown to have a natural interpretation as the
canonical box product for graphs via the bipartite representation functor, and
its associated box exponential is represented as homs entirely in the category
of incidence hypergraphs; with incidences determined by incidence-prism
mapping. The evaluation of the box exponential at paths is shown to correspond
to the entries in half-powers of the oriented hypergraphic signless Laplacian
matrix.Comment: 34 pages, 23 figures, 4 table
Pion-Nucleus Scattering at Medium Energies with Densities from Chiral Effective Field Theories
Recently developed chiral effective field theory models provide excellent
descriptions of the bulk characteristics of finite nuclei, but have not been
tested with other observables. In this work, densities from both relativistic
point-coupling models and mean-field meson models are used in the analysis of
meson-nucleus scattering at medium energies. Elastic scattering observables for
790
MeV/ on Pb are calculated in a relativistic impulse
approximation, using the Kemmer-Duffin-Petiau formalism to calculate the
nucleus optical potential.Comment: 9 page
