This paper proposed a kind of clustering algorithm based on square inaccuracy density. This algorithm adopted Square Inaccuracy density Function to fix on the parameter in clustering algorithm in order to avoid the problem caused by the random and subjective setting of the initial center of mass. In addition, this algorithm also brought in backtrack(More)
The density based distributed clustering algorithm DBDC has a higher time complexity in the process of distributed clustering. We proposed an improved density based distributed clustering algorithm. This algorithm used a data grid mapping method which mapped data object to the space grid first in the local level to improve the efficiency of the(More)
able coupler device called programmable coupler ladder, based on Titanium diffused lithium niobate waveguide and Y-junction reflector. Unlike the traditional serial to parallel converter, the coupler ladder sorts the output bits in the time axis using a built-in delay waveguide. With a proper control signal it can perform signal processing at the bit level.(More)
