    The Sampling Theorem and Several Equivalent Results in Analysis (2000)
    Springer
    Journal of computational analysis and applications 2 (2000), S. 333-371 
    Details
    ISSN: 1572-9206
    Keywords: sampling theorem ; Cauchy's integral formula ; Poisson's summation formula ; Fourier analysis ; complex analysis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics
    Notes: Abstract First we show that several fundamental results on functions from theBernstein spaces $$B_\sigma ^p $$ (such as Bernstein's inequality andthe reproducing formula) can be deduced from a weak form of the classicalsampling theorem. In §3 we discuss the mutual equivalence of thesampling theorem, the derivative sampling theorem and a harmonic functionsampling theorem. In §§4–6 we discuss connections between thesampling theorem and various important results in complex analysis andFourier analysis. Our considerations include Cauchy's integral formula,Poisson's summation formula, a Gaussian integral, certain properties ofweighted Hermite polynomials, Plancherel's theorem, the maximum modulusprinciple, and the Phragmén–Lindelöf principle.

    Spin density distribution in dialkyl oxalate radical anionsESR Studies on Carboxylic Esters, Part 9. For Part 8, see Ref. 1. (1988)

    Notes: The isotropic and anisotropic ESR spectra of dialkyl oxalate radical anions, including derivatives which were labelled with 13C or 17O in the carbonyl and 2H or 13C in the alkyl groups, were measured. The spin density distribution as determined from the experimental nuclear hyperfine coupling constants agrees very well with MNDO-CI calculations. As a consequence of the strictly planar structure of the radical anions, E/Z isomers are observed.

    Structure and Soot Properties of Nonbuoyant Ethylene/Air Laminar Jet Diffusion Flames (2000)
    In:  Other Sources
    Details
    Publication Date: 2019-07-10
    Description: The structure and soot properties of round, soot-emitting, nonbuoyant, laminar jet diffusion flames are described, based on long-duration (175-230/s) experiments at microgravity carried out on orbit In the Space Shuttle Columbia. Experiments] conditions included ethylene-fueled flames burning in still air at nominal pressures of 50 and 100 kPa and an ambient temperature of 300 K with luminous Annie lengths of 49-64 mm. Measurements included luminous flame shapes using color video imaging, soot concentration (volume fraction) distributions using deconvoluted laser extinction imaging, soot temperature distributions using deconvoluted multiline emission imaging, gas temperature distributions at fuel-lean (plume) conditions using thermocouple probes, not structure distributions using thermophoretic sampling and analysis by transmission electron microscopy, and flame radiation using a radiometer. The present flames were larger, and emitted soot men readily, than comparable observed during ground-based microgravity experiments due to closer approach to steady conditions resulting from the longer test times and the reduced gravitational disturbances of the space-based experiments.
