In order to efficiently improve the prediction accuracy, two load forecasting model based on fuzzy theory are presented, which are fuzzy clustering model and improved fuzzy regression analysis model .The method of fuzzy clustering is used to divide the area by the similar feature of load increasing. The new division is promising to improve the result of evident degree of clustering index to pow...

Control charts are widely used in industry as a tool to monitor process characteristics. Deviations from process targets can be detected based on the evidence of statistical significance. The control chart helps to take decisions such as the need for machine or technology replacement to monitor the process with categorical observations. Fuzzy logic is used to cram the uncertainty and vagueness ...

This paper investigates two aspects of using Fuzzy Logic with a GIS: The use of non-conventional aggregation operators for conjunctive and disjunctive reasoning and the use of weights when combining aggregates of different significance to the classification. Two methods of weighting are used, weights as powers of the membership functions, and the novel concept of membership functions that take ...

‎In this article we introduce $mu$-filtered fuzzy module with a family of fuzzy submodules.  It shows the relation between $mu$-filtered fuzzy modules and crisp filtered modules by level sets. We investigate fuzzy topology on the $mu$-filtered fuzzy module and apply that to introduce fuzzy completion. Finally we extend Krull's intersection theorem of fuzzy ideals by using concept $mu$-adic comp...

Using WMAP 5 year data, we look for the average Sunyaev-Zel’dovich effect (SZE) signal from clusters of galaxies by stacking the regions around hundreds of known Xray clusters. We detect the average SZE at a very high significance level. The average cluster signal is spatially resolved in the W band. This mean signal is compared with the expected signal from the same clusters calculated on the ...

We present deep spectroscopic data for a 24-object subsample of our full 41-object z ∼ 0.5 radio galaxy sample in order to investigate the evolution of the Fundamental Plane of radio galaxies.We find that the low-luminosity, FRI-type, radio galaxies in our sample are consistent with the local Fundamental Plane of radio galaxies defined by Bettoni et al. when corrected for simple passive evoluti...

We investigate the redshift dependence of the contribution to the extragalactic farinfrared/sub-millimeter background from galaxies detected by the Spitzer Space Telescope at 8μm and 24μm. Using seven-band optical to mid-infrared photometry, we estimate photometric redshifts for the Spitzer sources which appear to be mostly L∗ galaxies at a median redshift of z = 1.0. These sources, extracted f...

BACKGROUND Gender-based violence is an important risk factor for adverse reproductive health (RH). Community-level violence may inhibit young women's ability to engage in safer sexual behaviors due to a lack of control over sexual encounters. Few studies examine violence as a contextual risk factor. METHODS Using nationally representative data from five African countries, the association betw...
