This correspondence deals with the problem of determining the source coherency structure and estimation of directions of arrival in the presence of coherent signals. The method is closely related to the smoothed rank profile (SRP) algorithm presented in [3], which Manuscript received July 20, 1987; revised October 3, 1988. This work was supported by the Naval Physical and Oceanographic Laborato...

A major goal of this work is to specify some steps of the process by which participants maintain coherency in their conversations. The underlying element of the analysis is a construct called a 'context space'. Roughly, a group of utterances that refers to a single issue or episode forms the basis for a context space. Superficially a conversation is a sequence of utterances; at a deeper level i...

in this paper, a block-based method in wavelet domain for sar image coding is presented based on the ezbc algorithm. to better preserve edges and textural structure in sar images, instead of using traditional dyadic wavelet transform, a packet wavelet is employed. to improve the efficiency of the ezbc algorithm for sar image coding, a modified version of this algorithm, is proposed. this modifi...

Many books on polarization give tables of Mueller matrices. The coherency matrix has been found useful for interpretetion the matrix. Here we a table matrices M, C, and factors F different components systems. is not given some complicated nondeterministic cases. In many cases, though, very simple form. particular, expressions general case an homogeneous elliptic diattenuating retarder. Differen...

-This paper presents the application to the identification of coherent generators in a power system based on the fuzzy c-means clustering. In view of the conceptual appropriateness and computational simplicity, the fuzzy c-means give a fast and flexible method for clustering analysis. At first, the coherency measures are derived from the time-domain responses of generators to reveal the relatio...

The paper presents a solution for designing a cache coherency state machine for a multiprocessor system with error/correcting capabilities for the unidirectional errors and the used resources implied by a FPGA implementation of our solution. The cache coherency method used is based on the MESI protocol. The implementation is realized with FPGA by using the ALTERA Program.
