A problem solving domain for the application of artificial intelligence (AI) methods towards knowledge discovery for the purposes of modelling and forecasting is urban air quality. This domain has the specific characteristic that the key parameters of interest (pollutant concentration criteria) have multiple temporal (and spatial) scales. The present paper(More)
Air pollution can affect health and well-being of people and ecosystems. Due to the health risk posed for sensitive population groups, it is important to provide with hourly and daily forecasts of air pollution. One way to assess air pollution is to make use of the Common Air Quality Index (CAQI) of the European Environment Agency (EEA). In this paper we(More)
The tremendous effects of air quality in large cities have been considered a severe environmental problem all over the world. Therefore, the international community agreed to develop air quality standards to monitor and control pollution rates around industrial communities. Harmful emission into the air is a sign that could extremely affect man's(More)
We address the problem of recognizing real flat objects from two-dimensional images. A newm ethod is proposed which has mainly been designed to handle complexo bjects and performs under occlusion and similarity transformations. Matching operates hierarchically,g uided by a Curvature Scale Space (CSS) segmentation scheme,a nd takes advantage ofi mportant(More)
