Network and computer courses need dedicated laboratories for students to carry out hands-on assignments and course projects. Typically, these projects require each student to be given administrative access to an entire, isolated network of computers. The obvious approach of creating one dedicated physical network for each student is prohibitively expensive, both in terms of hardware costs, as w...

In this paper we propose a genetic algorithm (GA) for solving the DNA fragment assembly problem in a computational grid. The algorithm, which is named GrEA, is a steady-state GA which uses a panmitic population, and it is based on computing parallel function evaluations in an asynchronous way. We have implemented GrEA on top of the Condor system, and we have used it to solve the DNA assembly pr...

Number of Papers published in peer-reviewed journals: Final Report: STIR: High Performance Thermoelectric Cryo-coolers based on II-VI Low Dimensional Structures Report Title This program performed material design for high-performance thermoelectric (TE) cooler with a figure-of-merit ZT > 3. The cooler is fabricated from HgCdTe using a low dimensional superlattice structure. The TE coolers can o...

The rapid development of language tools using machine learning techniques for less computerized languages requires appropriately tagged corpus. A Bengali news corpus has been developed from the web archive of a widely read Bengali newspaper. A web crawler retrieves the web pages in Hyper Text Markup Language (HTML) format from the news archive. At present, the corpus contains approximately 34 m...

A new polar reverse phase stationary phase has permitted our group to develop and validate an isocratic HPLC method for the simultaneous determination of acetaminophen, phenylephrine and chlorpheniramine in capsules as pharmaceutical formulation after their dissolution test. Final optimised chromatographic conditions employed a Supelco Discovery HS PEG column (polyethylene glycol), 5 microm, 15...

Infrared emission has been detected from normal elliptical galaxies and from clusters of galaxies at 60μm and 100μm with the IRAS satellite. In both cases, the emission has the characteristics of cool dust with a temperature near 30K. For the elliptical galaxies, there is a correlation between the optical luminosities and the far infrared luminosities. The likely source of the dust in these sys...

OBJECTIVE Intense long-duration exercise has been associated with immunosuppression, which affects natural killer cells, lymphokine-activated killer cells, and lymphocytes. The mechanisms involved, however, are not fully determined and seem to be multifactorial, including endocrine changes and alteration of plasma glutamine concentration. Therefore, we evaluated the effect of branched-chain ami...

It has been proposed that the enrichment in noble gases found by Galileo in Jupiter’s atmosphere can be explained by their delivery inside cold planetesimals. We propose instead that this is a sign that the planet formed in a chemically evolved disk and that noble gases were acquired mostly in gaseous form during the planet’s envelope capture phase. We show that the combined settling of grains ...

Massively parallel collaboration and emergent knowledge generation is described through a large scale survey for archaeological anomalies within ultra-high resolution earth-sensing satellite imagery. Over 10K online volunteers contributed 30K hours (3.4 years), examined 6,000 km², and generated 2.3 million feature categorizations. Motivated by the search for Genghis Khan's tomb, participants we...

The detection of NH3 inversion lines up to the (J,K) = (6, 6) level is reported toward the central regions of the nearby galaxies NGC253, Maffei 2, and IC 342. The observed lines are up to 406K (for (J,K) = (6, 6)) and 848K (for the (9, 9) transition) above the ground state and reveal a warm (Tkin = 100 . . . 140K) molecular component toward all galaxies studied. The tentatively detected (J,K) ...
