Pandemetrics: systematically assessing, monitoring, and controlling the evolution of a pandemic

2022

AbstractThe still ongoing pandemic of SARS-CoV-2 virus and COVID-19 disease, affecting the population worldwide, has demonstrated the need of more accurate methodologies for assessing, monitoring, and controlling an outbreak of such devastating proportions. Authoritative attempts have been made in traditional fields of medicine (epidemiology, virology, infectiology) to address these shortcomings, mainly by relying on mathematical and statistical modeling. However, here, we propose approaching the methodological work from a different, and to some extent alternative, standpoint. Applied systematically, the concepts and tools of statistical engineering and quality management, developed not onl…

Optimization of Low-Cost Monitoring Systems for On-Site Earthquake Early-Warning of Critical Infrastructures

2020

In the last years, monitoring systems based on low-cost and miniaturized sensors (MEMS) revealed as a very successful compromise between the availability of data and their quality. Also applications in the field of seismic and structural monitoring have been constantly increasing in term of number and variety of functions. Among these applications, the implementation of systems for earthquake early warning is a cutting-edge topic, mainly for its relevance for the society as millions of peoples in various regions of the world are exposed to high seismic hazard. This paper introduces the optimization of an already established seismic (and structural) monitoring system, that would make it suit…

National cyber threat prevention mechanism as a part of the E-EWS

2020

The research will find out feature-based functionalities concerning the national cybersecurity system HAVARO and how the system is possible to implement to the EU level early warning system. The research based on interviews, official materials concerning the HAVARO information sharing system, scientific literature and other official published documents. The European level decision-makers have recognized that lack of cooperation between EU member countries effects to completely public safety atmosphere. The only problem does not consist of separate operational functions and procedures between national Cyber situation centers. One main problem is that the European Union does not have a common…

Enhancing the European Cyber Threat Prevention Mechanism

2021

This research will determine how it is possible to implement the national cyber threat prevention system into the EU level Early Warning System. Decision makers have recognized that the lack of cooperation between EU member countries affects public safety at the international level. Separate operational functions and procedures between national cyber situation centers create challenges. One main problem is that the European Union does not have a common cyber ecosystem concerning intrusion detection systems for cyber threats. Also, privacy and citizens’ security as topics are set against each other. The research will comprise a new database for the ECHO Early Warning System concept.

A new picking algorithm based on the variance piecewise constant models

2022

AbstractIn this paper, we propose a novel picking algorithm for the automatic P- and S-waves onset time determination. Our algorithm is based on the variance piecewise constant models of the earthquake waveforms. The effectiveness and robustness of our picking algorithm are tested both on synthetic seismograms and real data. We simulate seismic events with different magnitudes (between 2 and 5) recorded at different epicentral distances (between 10 and 250 km). For the application to real data, we analyse waveforms from the seismic sequence of L’Aquila (Italy), in 2009. The obtained results are compared with those obtained by the application of the classic STA/LTA picking algorithm. Althoug…

USING A X-BAND WEATHER RADAR FOR AN URBAN AREA EARLY WARNING SYSTEM AND THE STUDY OF PRECIPITATION DYNAMICS.

2014

The development and availability of X-band radar instruments occurred in the last years, provides the scientific community of an important tool for the study, the characterization and the operational usage of detailed precipitation information. The hydrology laboratory of the Department of Civil, Environmental, Aerospace Engineering, and Materials (DICAM) at the University of Palermo, has installed a X-band weather radar in the urban area of Palermo (Italy) along with a set of advanced auxiliary instruments that help on exploiting the precipitation information. A raingauge network of 18 tipping bucket gauges spread over the observed area is available for the calibration of precipitation map…
