User-perceived application-level performance is key to the adoption and success of UMTS services and infrastructure.
We first present the VoIP architecture based on available technologies for ENUM-based IP-address resolution of the E.164 telephone numbers, SIP signaling between the service provider VoIP servers,
In this letter, we report a fast and endless polarization controller based on lead lanthanum zirconate titanate (PLZT) ceramic programmable waveplates.
Mixtures of poly(vinylidene fluoride), PVDF, and poly(methyl methacrylate), PMMA, are known to exhibit lower critical solution temperature (LCST) behavior near 350C, well above the degradation tem
Voyager 2 Low Energy Charged Particles (LECP) data from the magnetosphere of Uranus have been analyzed to obtain proton and electron phase space density profiles.
Observations of energetic neutral atoms (ENA) in the energy range 26-52 keV are reported from four occasions during geomagnetically disturbed periods.
We report observations of solar energetic particles obtained by the HI-SCALE and COSPIN/LET instruments onboard Ulysses during the period of isolated but intense solar activity in 2006 December, in
We present recent energetic particle measurements from 1 20 MeV/n recorded by the Ulysses/COSPIN/LET instrument from mid-October to the end of November 2003 and from May 2004 to the end of February
Thw Low Energy Charged Particle (LECP) instrument on Voyager 2 measured low-energy electrons (E >~ 22 keV) and ions (E >~ 28 keV) within the magnetosphere of Neptune.
Energetic trapped electrons were measured with the Energetic Particle Instrument (EPI) on the Galileo Jupiter Probe. Samples were taken from inside Io's orbit to just above Jupiter's atmosphere.
