One of the key problems in coping with deliberate or accidental atmospheric releases is the ability to reliably predict the individual exposure during the event. Furthermore, for the implementation of countermeasures, it is essential to predict the maximum expected dosage and the exposure time within which the dosage exceeds certain health limits.

The University of Western Macedonia (UoWM) has recently set up an operational system for predicting air quality in the Florina–Ptolemais–Kozani basin in Western Macedonia, Greece. This is a mountainous basin where around 65% of the total energy production of Greece takes place in lignite power plants. The concentrations of PM10 is the main air quality(More)
The present paper discusses the application of localized linear models for the prediction of hourly PM10 concentration values. The advantages of the proposed approach lies in the clustering of the data based on a common property and the utilization of the target variable during this process, which enables the development of more coherent models.

The functioning and viability of modern societies is heavily depended upon the continuous and uninterruptible operation of critical infrastructures. Surface transportation systems are in the heart of the daily lives of millions of citizens globally. As such, they are open and freely accessible by design and in the past have been exploited for terrorism(More)
