We propose a robust and efficient algorithm called ROCKET for clustering large-scale transaction databases. ROCKET is a divisive hierarchical algorithm that makes the most of recent hardware architecture. ROCKET handles the cases with the small and the large number of similar transaction pairs separately and efficiently. Through experiments, we show that ROCKET achieves high-quality clustering ...

Yellow rocket, Barbarea vulgaris (R. Br.) variety arcuata, was evaluated as a trap crop for diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), in cabbage, Brassica oleracea L. variety capitata, in 2003 and 2004. In 2003, the numbers of P. xylostella larvae found in field plots of cabbage alone were 5.2-11.3 times higher than those on cabbage plants in plots that included cab...

NASA’s Endurance sounding rocket (yard No. 47.001) will launch from Ny Ålesund, Svalbard in May 2022 on a solid fueled Oriole III-A vehicle. Its \(\sim19\) minute flight carry it to an altitude of \(\sim780~\text{km}\) above Earth’s sunlit polar cap. objective is make the first measurement weak “ambipolar” electric field generated by ionosphere. This thought play critical role upwelling and esc...

The characteristics of turbulent plasma in the winter cusp ionosphere is studied based on in-situ data from Investigation Cusp Irregularities (ICI) sounding rockets. electron density fluctuations ICI-2 and ICI-3 missions have been analyzed for whole flight, using advanced time-series analysis techniques. autocorrelation scale indicative turbulence integral marks onset cascade large to small sca...

Electric field and plasma density data gathered on a sounding rocket launched from Uchinoura Space Center, Japan, reveal a complex electrodynamics associated with sporadic-E layers and simultaneous observations of quasiperiodic radar echoes. The electrodynamics are characterized by spatial and temporal variations that differed considerably between the rocket’s upleg and downleg traversals of th...

crops that better tolerate weed competition or preempt resources from weeds may reduce dependence on herbicides and benefit an integrated weed management program. a field trail was conducted to determine the morphophysiological characteristics affecting tolerance and weed suppressive ability of some winter wheat cultivars in competition with rocket. the experimental treatments consisted of eigh...
