Particulate air pollution is associated with a range of effects on human health, including effects on the respiratory and cardiovascular systems, asthma and mortality. Hence, the development of an efficient forecasting and early warning system for providing air quality information towards the citizen becomes an obvious and imperative need. The objective of this work was to investigate that fore...

background: determining the temporal variation and forecasting the incidence of smear positive tuberculosis (tb) can play an important role in promoting the tb control program. its results may be used as a decision-supportive tool for planning and allocating resources. the present study forecasts the incidence of smear positive tb in iran. methods: this a longitudinal study using monthly tuberc...

This paper consists in a preliminary study as part of PIDOP (Processes Influencing Democratic Ownership and Participation), project involving eight European countries (Portugal, Germany, Turkey, Czech Republic, Sweden, Italy, Belgium and United Kingdom). The main goal of the study is to provide an understanding of civic and political participation of young people in Portugal. The concept of “po...

Prediction has been widely studied for many years as time series analysis (Box & Jenkins, 1970; Tong, 1990). Traditionally, prediction is based on a statistical model that is either linear or nonlinear (Li et al., 1990). Recently, several studies have adopted neural fuzzy networks to predict time series (Cowder, 1990; Kasabov & Song, 2002; Ling et al., 2003). Researchers have discussed that the...

For any non-compact Riemannian manifold M of dimension n ≥ 2 we previously defined a function λM : M×M → R+ = R+∪{+∞] only dependent on the conformal structure of M , and proved that for a class of manifolds containing all the proper subdomains of R, λ 1 n M was a distance on M [F1, F2]. The case of a domain G of R has been the object of several investigations leading to estimations of λG[V1, ....

Two experiments explore the effects of mood on category learning. In the first experiment subjects were put into either a negative or a neutral mood before completing one of two category-learning tasks. Negative mood briefly impaired rulebased category learning but this impairment did not persist throughout the task. Negative mood did not influence nonrule-based learning. In a second study subj...
