Vibrational energy transfer in shock‐heated norbornene
(The American Institute of Physics, 1995-09-22)
Recently, Kiefer et al. [J. H. Kiefer, S. S. Kumaran, and S. Sundaram, J. Chem. Phys. 99, 3531 (1993)] studied shock‐heated norbornene (NB) in krypton bath gas using the laser‐schlieren technique and observed vibrational ...
Recent results from the CASA‐MIA experiment
(The American Institute of Physics, 1995-07-10)
Results from the CASA‐MIA cosmic ray experiment are presented. I discuss the apparatus and its performance, including new results on the identification of the shadows of the sun and moon used to determine the angular ...
Compact large‐range cryogenic scanner
(The American Institute of Physics, 1995-03)
We describe the construction and operation of a large‐range piezoelectric scanner, suitable for various scanning probe microscopies such as magnetic force, atomic force, and Hall probe microscopies. The instrument is compact ...
Heat conduction in Ba 1−x K x BiO 3
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1995-08)
We have investigated heat conduction of single crystal Ba 1−x K x BiO 3 in the temperature range of 2–300 K and in a magnetic field of up to 6 Tesla. Temperature dependence of thermal conductivity κ(T) reveals the participation ...
Flow characteristics of gas-liquid-particle mixing in a gas-stirred ladle system with throughflow
(Springer-Verlag, 1995-09)
An experimental study is performed on air-liquid-particle mixing, resulting from an air-particle mixture injected into a liquid flowing through a slender ladle. Flow visualization combined with image processing is employed ...
Two 1993 Kamchatka earthquakes
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1995-09)
Two earthquakes occurred in 1993 off southern Kamchatka. They have similar surface wave magnitudes, focal mechanisms, and depths, but have distinctly different characteristics. The November earthquake is a standard or ...
Control of composition and structure for molybdenum nitride films synthesized using ion beam assisted deposition
(The American Institute of Physics, 1995-05-15)
The purpose of the research described in this article was to synthesize molybdenum nitride films with well‐defined structures and stoichiometries using ion beam assisted deposition (IBAD). Approximately 400 nm thick films ...
Computer-aided classification of mammographic masses and normal tissue: linear discriminant analysis in texture feature space
(IOP Publishing Ltd, 1995-05-01)
The authors studied the effectiveness of using texture features derived from spatial grey level dependence (SGLD) matrices for classification of masses and normal breast tissue on mammograms. One hundred and sixty-eight ...
Second order Raman spectroscopy of the wurtzite form of GaN
(The American Institute of Physics, 1995-06-01)
We report on Raman scattering by phonon pairs in GaN films grown on sapphire substrates by plasma‐enhanced molecular beam epitaxy. The first order data are consistent with results obtained from GaN bulk crystals of the ...
Investigation of reactive‐ion‐etch‐induced damage of InP/InGaAs multiple quantum wells by photoluminescence
(The American Institute of Physics, 1995-08-01)
The effects of CH4/H2 reactive ion etching (RIE) on the optical properties of an InP/InGaAs multiple‐quantum‐well structure have been investigated by low‐temperature photoluminescence (PL). The structure consisted of eight ...
