A staggered-mesh finite-difference numerical method for solving the transport equations in low pressure rf glow discharges
(Elsevier, 1988-07)
A numerical model of a low pressure parallel plate rf glow discharge is presented based on a self-consistent formulation of the energy-momentum conservation equations for electrons, the continuity equations for both electrons ...
Measurement of upper limits for the decay widths of D*+ and D*0
(Elsevier, 1988-10-06)
Upper limits for the decay widths of the D*+ and D*0 mesons have been measured using data from e+e- annihilations at [radical sign]s=29 GeV obtained with the High Resolution Spectrometer at PEP. We find [Gamma]D*+ c2 at ...
Measurements of the dynamics and coupling of the equatorial thermosphere and the F-region ionosphere in Peru
(Elsevier, 1988)
Simultaneous Fabry-Perot Interferometer (FPI) and Incoherent Scatter Radar (ISR) observations from Arequipa and Jicamarca, Peru, respectively, were obtained on 24 and 25 September 1986, during which there was substantial ...
Unsteady flow in rotating drums using laser Doppler velocimetry
(Springer-Verlag, 1988-01)
Non-destructive measurements by laser Doppler velocimetry is employed to study unsteady flow in a hollow drum filled with liquid. The drum is suddenly accelerated from rest or is suddenly decelerated from a steady rotation ...
The strong CP problem in orbifold compactifications and an SU(3)[circle times operator]SU(2)[circle times operator]U(1)n model
(Elsevier, 1988-06-30)
We point out that the anomalous U(1)'s arising frequently in nonstandard embeddings of orbifold compactification is the needed Peccei-Quinn symmetry which can be broken at the intermediate scale. We show this in an orbifold ...
Modeling of an electron cyclotron resonance heated mirror plasma for highly charged ion and soft x‐ray sources
(The American Institute of Physics, 1988-08-01)
A model is described for predicting equilibrium ion charge state distributions and soft x‐ray emissions for highly charged ion plasmas confined in magnetic mirrors. Such a plasma would be generated and sustained with ...
Magnetohydrodynamic flow and heat transfer about a rotating disk with suction and injection at the disk surface
(Elsevier, 1988)
This paper studies the effects of an axial magnetic field on the flow and heat transfer about a porous rotating disk. Using modern quasi-Newton and globally convergent homotopy methods, numerical solutions are obtained for ...
Rarefactions and large time behavior for parabolic equations and monotone schemes
(Springer-Verlag, 1988-12)
We consider the large time behavior of monotone semigroups associated with degenerate parabolic equations and monotone difference schemes. For an appropriate class of initial data the solution is shown to converge to ...
A unified theory of aerosol coagulation
(IOP Publishing Ltd, 1988-06-14)
A unified theory of the coagulation of aerosols is presented based upon the solution of a generalised diffusion equation which describes classical diffusion due to Brownian and turbulent motion as well as the effect of an ...
An optically detected magnetic resonance study of Mn4+ in Cs2GeF6 and K2GeF6
(Elsevier, 1988-11-15)
The photoexcitation and photoluminescence spectra (2E 4A2) of MnF62- diluted in Cs2GeF6 and K2GeF6 host lattices have been recorded at liquid helium temperature. The manganese coordination geometry is Oh in Cs2GeF6 and ...
