Nonlinear vortex trail dynamics
(The American Institute of Physics, 1988-05)
The nonlinear evolution of periodic disturbances on vortex trails is considered. In addition to following small initial perturbations, large amplitude initial disturbances of the vortex trails are also studied. It is shown ...
Entropy production in flames
(Elsevier, 1988-09)
Thermodynamic foundations of the thermal entropy production are rested on the concept of lost heat, (Q/T) [delta]T. The thermomechanical entropy production is shown to be in terms of the lost heat and the lost work as ...
The magnetic moment of the neutrino and its implications for neutrino signal from SN1987A
(Elsevier, 1988-10-13)
If the magnetic moment of the neutrino is to provide a resolution of the solar neutrino puzzle without violating the constraints implied by SN1987A observations, there must exist non-standard interactions of the right-handed ...
Neutrinos from SN1987a in the IMB detector
(Elsevier, 1988-02-01)
A burst of eight neutrino events preceding the optical detection of the supernova in the Large Magellanic Cloud has been observed by the IMB detector. The events span an interval of 6 s and have visible energies in the ...
The mercedes-benz approach to [gamma]-ray astronomy
(Elsevier, 1988-02-01)
The sensitivity requirements for ground-based [gamma]-ray astronomy are reviewed in the light of the most reliable estimates of stellar fluxes above 100 GeV. Current data strongly favor the construction of detectors with ...
The chlorine nuclear quadrupole coupling tensor in chlorotrifluoroethylene
(Elsevier, 1988-12)
The 273 hyperfine components from 56 rotational transitions of chlorotrifluoroethylene were measured with a Fourier transform microwave spectrometer. A global least-squares fit was made to the rotational constants, quartic ...
Differential and integral methods for three-dimensional inverse scattering problems with a non-local potential
(IOP Publishing Ltd, 1988-05-01)
The inverse scattering problem for the three-dimensional Schrodinger equation with a non-local potential diagonal in the radius variable is considered. Generalised Gel'fand-Levitan and Marchenko integral equations are ...
Independent oscillator model of a heat bath: Exact diagonalization of the Hamiltonian
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1988-10)
The problem of a quantum oscillator coupled to an independent-oscillator model of a heat bath is discussed. The transformation to normal coordinates is explicitly constructed using the method of Ullersma. With this ...
Mode localization and eigenvalue loci veering phenomena in disordered structures
(Elsevier, 1988-11-08)
An investigation of the effects of disorder on the modes of vibration of nearly periodic structures is presented. It is shown that, in structures with close eigenvalues, small structural irregularities result in both strong ...
Energy dependence of infrared emission from azulene C–H stretching vibrations
(The American Institute of Physics, 1988-05-15)
New data are described on the energy dependence of infrared fluorescence (IRF) from the C–H stretch modes (∼3050 cm−1) of vibrationally excited azulene (C10H8). An optoacoustic method was used to measure the absorbed laser ...
