Electricity has become an important concern in today’s society. This is due to the fact that electric grid now a greater number of non-linear components. The AC-powered locomotive one these aim this paper was model and predict reactive power produced by AC locomotive. presents study on modelling prediction locomotives. Reactive flow significant impact network voltage levels efficiency. research...

The Cisangkuy sub-watershed is part of the Citarum watershed with ±300 km river length. total area in line potential water resources which quite good, but over time hydrological condition site has decreased. Decreasing state due to changes land use and cover from year indicated by high discharge flooding rainy season. This study aims find optimal location artificial recharge maintain balance su...

Fuzzy theory appears to be extremely effective at handling dynamic, non-linear and noisy data, especially when the underlying physical relationships are not fully understood. Since hydrologists are still uncertain about many of the aspects of the physical processes in the watershed, fuzzy theory has proved to be a very attractive tool enabling them to investigate such problems. The effectivenes...

In most cases, due to the plethora of data values, it is unrealistic for domain experts to mine useful knowledge from the database. Motivated by this, a novel approach for optimized clustering is developed in this paper. The proposed approach is genetically oriented to mine vital information incorporated in large databases avoiding entrapment in local optima and sensitivity to initialization. T...

Despite of acquiring popularity among researchers, the implementations of ANFIS-based models face problems when the number of rules surge dramatically and increase the network complexity, which consequently adds computational cost. Essentially, not all the rules in ANFIS knowledge-base are the potential ones. They contain those rules which have either minor or no contribution to overall decisio...

Alteration in gene transcripts is related to a wide spectrum of physiological and pathological changes in cells. Therefore, the identification of differential gene expression can be used to understand biological processes at a molecular level [1-4]. Various techniques such as Expressed Sequence Tags (EST), differential display, Serial Analysis of Gene Expression (SAGE), cDNA microarray, and sub...

potato image segmentation is an important part of image-based potato defect detection. this paper presents a robust potato color image segmentation through a combination of a fuzzy rule based system, an image thresholding based on genetic algorithm (ga) optimization and morphological operators. the proposed potato color image segmentation is robust against variation of background, distance and ...

We introduce and investigate a new type of reductions between counting problems, which we call subtractive reductions. We show that the main counting complexity classes #P, #NP, as well as all higher counting complexity classes # · kP, k 2, are closed under subtractive reductions. We then pursue problems that are complete for these classes via subtractive reductions. We focus on the class #NP (...
