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 ...
Computer-aided simulation of a rotary sputtering magnetron
(The American Institute of Physics, 2004-06-01)
In the past, computer-aided simulation of sputtering magnetron has been applied mainly to planar cathodes with flat target surfaces. In this work, we have simulated the target erosion profile of a cylindrical rotary magnetron ...
Thin-film ferromagnetic semiconductors based on Sb2−xVxTe3Sb2−xVxTe3 with TCTC of 177 K177K
(The American Institute of Physics, 2005-09-12)
Thin-film ferromagnetic semiconductors Sb2−xVxTe3Sb2−xVxTe3 with the Curie temperature as high as 177 K177K were prepared on sapphire (0001) substrates by molecular-beam epitaxy. Films of Sb2−xVxTe3Sb2−xVxTe3 with xx up ...
CO2‐CS2 Geiger Counter
(The American Institute of Physics, 1961-08)
Experiments on the mechanism and characteristics of a CO2‐CS2 Geiger counter are reported, and circuits and methods of operation which satisfy the special requirements are described. Counter: The active part is 2⅞ in. in ...
Ondelettes and phase cell cluster expansions, a vindication
(Springer-Verlag, 1987-09)
Y. Meyer has recently developed a particularly useful o.n. basis for L 2 ( R d ). Expansions using this basis, i.e. expansions into “ondelettes” or “wavelets,” have yielded important new results in soft and hard analysis. ...
Experimental test of the Siberian Snake concept
(The American Institute of Physics, 1989-05-05)
We are now beginning an accelerator physics experiment at the Indiana University Cyclotron Facility (IUCF) proton Cooler Ring, which will be the first experimental test of the Siberian Snake concept for dealing with ...
The effect of frequency-mismatched spontaneous emission on atom-field entanglement
(IOP Publishing, 2012)
A Schrödinger representation approach is used to calculate the atom-field dynamics following spontaneous emission by an atom in its excited state to a superposition of its two ground-state sublevels, in the case where ...
Fuel cells--II. Propane and propylene on Adams' platinum catalyst
(Elsevier, 1964-12)
In order to control the quantity of previously adsorbed hydrogen in fuel electrodes to be used with hydrocarbons, the use of Adams' platinum catalyst was investigated. Preferred procedures for electrode preparation were ...
Internal plasma potential profiles in a laboratory-model Hall thruster
(The American Institute of Physics, 2001-02)
The Plasmadynamics and Electric Propulsion Laboratory High-speed Axial Reciprocating Probe system is used in conjunction with a floating emissive probe to measure plasma potential in the discharge chamber of the P5 Hall ...
