This investigation considers the optimization of multiple gravity assist capture trajectories in the Jupiter system combining the well known Differential Evolution algorithm with different classes of constraint handling techniques. The trajectories are designed to reach a desired target orbit around Jupiter with minimum fuel consumption while satisfying mission design constraints on maximum thr...

We report 32 GHz absolute flux density measurements of the supernova remnant Cas A, with an accuracy of 2.4%. The measurements were made with the 1.5-meter telescope at the Owens Valley Radio Observatory. The antenna gain had been measured by NIST in May 1990 to be 0.505 ± 0.007 Jy . Our observations of Cas A in May 1998 yield Scas,1998 = 194.0 ± 4.7 Jy. We also report absolute flux density mea...

A radio telescope consisting of a receiver and a dual dipole antenna has been installed at high altitude station Darjeeling to detect solar and Jovian emissions at 20.1 MHz for receiving radio signal from both the Sun and the Jupiter. Signals received during September 2012 are analyzed to compare the Jovian bursts observed in predicted emission phases for the satellite Io of the Jupiter and the...

MUXING is a telephone-based conversational system that allows users to access weather information in Mandarin Chinese over the telephone. Although MUXING utilizes the same architecture as well as most of the same human language technology components as its English predecessor, JUPITER, some modifications to the system were necessary to account for differences between English and Mandarin Chines...

We have been actively collecting data within the JUPITER domain since the beginning of 1997. As was done in previous domains, we first developed a prototype JUPITER system and used it to collect spontaneous speech using a Wizard paradigm, with a human typist in the loop and subjects brought into the lab and given scenarios to solve. At the same time, we solicited read speech using both our Web-...

John Fryer, m.d. (Cantab.), f.r.s., may be rightly described as the most observant and learned of all the physicians and surgeons of the East India Company in the 17th century. He came out to India in 1673 and served at various settlements in this country and Persia till 1682. During his journey to his station, Surat, he visited Fort St. George and Masulipatam on the Coromandel coast, and Goa a...

Data on the composition and thermal structure, and the Lyman-alpha dayglow of Saturn when analyzed in conjunction with photochemical models of the hydrocarbons and the atomic hydrogen g reduction yield the homopause value of the eddy diffusion coefficient to be approximately 10 cm2 s-l. The equatorial value of the eddy diffusion coefficient at the homopause of Saturn is thus found to be approxi...
