One of the keys to constructing decision tree model is to choose standard for testing attribute, for the criteria of selecting test attributes influences the classification accuracy of the tree. There exists diversity choosing standards for testing attribute based on entropy, Bayesian, and so on. In this paper, the degree of dependency of decision attribute(More)
We propose and experimentally demonstrate a scheme to reduce the energy consumption of optical line terminal (OLT) in wavelength division multiplexing - orthogonal frequency division multiplexing - passive optical networks (WDM-OFDM-PONs). In our scheme, a wireless communication technique, termed layered modulation, is introduced to maximize the(More)
BACKGROUND Currently, cystoscopy and urine cytology are standard modalities in therapy monitoring and follow-up of bladder carcinoma (BC). Cystoscopy is an invasive and uncomfortable procedure while cytology has a limited value because it is operator-dependent and has low sensitivity. This study was to assess the accuracy of ImmunoCyt in detecting BC by(More)
We propose and experimentally demonstrate a hierarchical modulation scheme to improve power margin for orthogonal frequency division multiple access-passive optical networks (OFDMA-PONs). In a PON system, under the same launched optical power, optical network units (ONUs) have different power margins due to unequal distribution fiber lengths. The power(More)
