To overcome the shortcoming the counters of Count Bloom Filters are easy to be overflow when CBF counts the multiplicity of items in many emerging applications data streams with skewed distributions,this paper proposes an Adaptive Count Bloom Filter(ABF),which uses a scaleable logical counter instead of the fixed size physical counter and the logical counter consists of some physical counters.

The grating is recorded by two orthogonal linear polarization waves in liquid crystals doped with polymer, which diffracted orders can be controlled by the polarization of the probe beam.

It is shown that, for the skew distributional data, the robust estimation methods can better reflect the size and shape of the anomaly, especially the large-size weak anomaly, than the.

The method of synchroarray magnetoelluric sounding data processing is studied on the basis of the theoretical anaysis of MT curve static shift and other distortions due to surface terrain andnear-surface inhomogeneities.

The influence of dynamic bias voltage and vacuum on microstructure and properties of the coatings deposited by vacuum arc were studied.
