This paper introduces fuzzy belief nets (FBN). The ability to invert arcs between nodes is key to solving belief nets. The inversion is accomplished by defining closeness measures which allow diagnostic reasoning from observed symptoms to cause of failures. The closeness measures are motivated by a Lukasiewicz operator which takes into account the distance from an observed symptom set to the mo...

Karun River is the largest and most watery river in Iran. This river is the longest river which located just inside Iran and Ahvaz Metropolis drinking water supplied from Karun River as well (fa.alalam.ir). Karun River as the main source of water treatment plants in Ahvaz, like most surface waters affected by various contaminants which caused changes in water quality of the river (www.aww.co.ir...

you can find the name of nile river in most of the poetic collections in egypt and sudan. the beauty of this river occupies and captivates the mind of poets. therefore the poets write their best poems especially about this river. poems which have special style with a divine structure, strong words, beautiful glossary and worthy concepts. one of the most famous man among the poets is abdullah al...

Analyzing networks requires complex algorithms to extract meaningful information. Centrality metrics have shown to be correlated with the importance and loads of the nodes in network traffic. Here, we are interested in the problem of centrality-based network management. The problem has many applications such as verifying the robustness of the networks and controlling or improving the entity dis...

Today, publication of medical data faces high legal barriers. On the one hand, publishing medical data is important for medical research. On the other hand, it is neccessary to protect peoples’ privacy by ensuring that the relationship between individuals and their related medical data remains unknown to third parties. Various data anonymization techniques remove as little identifying informati...

This study aims at contributing to the literature on the effect of political competition on voting turnout. I test the Downsian Closeness Hypothesis (DCH) using data on runoffs elections in Hungary. This research design allows for estimating the effect of expected closeness using the variation of margins in the first round races to avoid the endogeneity problem inherent in ex post measures of c...

The 1st goal of this study was to investigate how online communication is related to the closeness of existing friendships. Drawing from a sample of 794 preadolescents and adolescents, the authors found that online communication was positively related to the closeness of friendships. However, this effect held only for respondents who primarily communicated online with existing friends and not f...

In this paper, Pitman closeness of sample order statistics to population quantiles of a locationscale family of distributions is discussed. Explicit expressions are derived for some specific families such as uniform, exponential and power function. Numerical results are then presented for these families for sample sizes n = 10, 15, and for the choices of p = 0.10, 0.25, 0.75, 0.90. The Pitman-c...
