Several research works have focused on supporting index access in MapReduce systems. These works have allowed users to significantly speed up selective MapReduce jobs by orders of magnitude. However, all these proposals require users to create indexes upfront, which might be a difficult task in certain applications (such as in scientific and social applications) where workloads are evolving or ...

5 This paper describes the transformation of the CSU-CHILL National Radar Facility from 6 a single-frequency (S-band) dual-polarization Doppler weather radar system to a dual7 frequency (S and X band) dual-polarization Doppler system with coaxial beams. A brief 8 history regarding the development of dual-wavelength radars is first presented. In the past 9 dual-wavelength measurements were used ...
