For example, it can generate runtime filter, push it to the probe side, and automatically penetrate it to the Scan node at the bottom, which drastically reduces the amount of data in the probe and increases join performance. The runtime filter in Doris supports In/Min/Max/Bloom filter....
When we do construction for Kylin, we always need to do the following: widen tables, de-duplicate columns, generate dictionaries, build cubes, etc. If there are 1000-2000 or more tasks per day, at least 10 or more tasks will fail to build, resulting in a lot of time to write a...
Born Doris Kappelhoff on April 3, 1922, she began her career as a big band singer in 1939. She later took to the screen, with roles in classic filmsRomance on the High Seas,Calamity Janeand Alfred Hitchcock’sThe Man Who Knew Too Much, among others. She also starred in her own sitco...
The goal of this study is to focus on the atmospheric drag estimation used to generate the new DORIS/IGN ignwd08 time series prepared for ITRF2008. We develop here a method to inter-compare different processing strategies. In a first step, by analyzing single-satellite solutions for a few ...
Firstly, if you have a positive real shock (i.e. productivity rises) this will put downward pressure on prices. Under an inflation target central banks would respond by easing policy, but this could generate asset bubbles. An NGDP target would allow prices to fall to reflect the increased pr...
The histogram comprises a series of buckets, wherein the statistics of each bucket comprises the upper and lower bounds of the bucket, the number of elements contained in the bucket, the number of all elements in the previous bucket, and the number of different values in the bucket. For ...

A single S-ribbon in a current tube will generate simple AC current when used as a generator and may be driven by simple AC current as a motor. By using two similar but mutually insulated S-ribbons in the same current tube, with uniformly spaced axial sections, two independent AC voltages...
4. A homopolar generator configured to generate a current when rotated by a mechanical torque comprising: at least one electrically conductive rotatable rotor configured to flow a current in a current path when the generator is rotated by a mechanical torque; a magnetic field source configured to...
