The micro-modem is a compact, low-power, underwater acoustic communications and navigation subsystem. It has the capability to perform low-rate frequency-hopping frequency-shift keying (FH-FSK), variable rate phase-coherent keying (PSK), and two different types of long base line navigation, narrow-band and broadband. The system can be configured to transmit(More)
Microsatellite DNA markers are consistently found to be more informative than other classes of markers in hexaploid wheat. The objectives of this research were to develop new primers flanking wheat microsatellites and to position the associated loci on the wheat genome map by genetic linkage mapping in the ITMI W7984 × Opata85 recombinant inbred line (RIL)(More)
 DNA marker-assisted selection was used to pyramid four bacterial blight resistance genes, Xa-4, xa-5, xa-13 and Xa-21. Breeding lines with two, three and four resistance genes were developed and tested for resistance to the bacterial blight pathogen (Xanthomonas oryzae pv. oryzae). The pyramid lines showed a wider spectrum and a higher level of resistance(More)
Bacterial blight (BB) of rice caused by Xanthomonas oryzae pv. oryzae (Xoo) is a major disease of rice in several countries. Three BB resistance genes, xa5, xa13 and Xa21, were pyramided into cv. PR106, which is widely grown in Punjab, India, using marker-assisted selection. Lines of PR106 with pyramided genes were evaluated after inoculation with 17(More)
In this paper, we explain the concept, characteristics & need of Big Data & different offerings available in the market to explore unstructured large data. This paper covers Big Data adoption trends, entry & exit criteria for the vendor and product selection, best practices, customer success story, benefits of Big Data analytics, summary and(More)
This paper describes the design and development of surface acoustic wave (SAW) filters proposed to be used in the analog mesh-processor payload of GSAT-7 satellite. Four high performance SAW filters with center frequencies in the range of 176 MHz to 183 MHz and band widths in the range of 0.78 MHz to 2.28 MHz are being developed for the payload.(More)
The population of India is extremely diverse comprising of more than 3,000 ethnic groups who still follow endogamy. Haemoglobinopathies are the commonest hereditary disorders in India and pose a major health problem. The data on the prevalence of β-thalassemias and other haemoglobinopathies in different caste/ethnic groups of India is scarce. Therefore the(More)
Leaf and stripe rusts are severe foliar diseases of bread wheat. Recently, chromosomes 5Mg from the related species Aegilops geniculata that confers resistance to both leaf and stripe rust and 5Ut from Ae. triuncialis conferring resistance to leaf rust have been transferred to bread wheat in the form of disomic DS5Mg(5D) and DS5Ut(5A) chromosome(More)
 Aegilops tauschii is the diploid D-genome progenitor of bread wheat (Triticum aestivum L. em Thell, 2n=6x=42, AABBDD). A genetic linkage map of the Ae. tauschii genome was constructed, composed of 546 loci. One hundred and thirty two loci (24%) gave distorted segregation ratios. Sixty nine probes (13%) detected multiple copies in the genome. One hundred(More)
BlueGene/L (BG/L) is a 64K (65,536) node scientific and engineering supercomputer that IBM is developing with partial funding from the United States Department of Energy. This paper describes one of the primary BG/L interconnection networks, a three dimensional torus. We describe a parallel performance simulator that was used extensively to help architect(More)
