Early Warning Systems for Food Security in West Africa: Evolution, Achievements and Challenges
2010
In West Africa, early warning systems (EWSs) for food security have been widely recognized to have contributed, in the last 20 years, to an improved ability to deal with famine emergencies. Nevertheless, despite the advancements in understanding of the environmental and socio-economic dynamics and despite the improved technologies, tackling food security remains a difficult task for decision makers as demonstrated by local food crises in many countries of the region. African Monsoon Multidisciplinary Analysis, while improving the understanding of the monsoon system, allowed us to better orient research challenges to provide EWS with improved products, effectively meeting the needs of end-us…
A fast and efficient picking algorithm for earthquake early warning application based on the variance piecewise constant models
2020
An earthquake warning system, or earthquake early warning system, is a system of accelerometers, seismometers, communication, computers, and alarms that is devised for notifying adjoining regions of a substantial earthquake while it is in progress. This is not the same as earthquake prediction, which is currently incapable of producing decisive event warnings. The implementation of efficient and computationally simple picking algorithm is necessary for this purpose, as well as automatic picking of seismic phases for seismic surveillance and routine earthquake location for fast hypocenter determination. In this paper a method for picking based on the detection of signals changes in variance …
Recognizing Early warning Signs in Transportation Services
2018
The transport services can vary in complexity, and can be carried out in short or long supply chains. Market observations indicate that logistics services including transport service become increasingly sophisticated, by far exceeding their traditional perception. They begin to resemble projects characterized by singularity, uniqueness, temporariness, limited budget, and, occasionally, innovativeness. Therefore, they are often treated as a specific type of projects, called logistics projects. The aim of the paper is to present the essence and characteristics of transportation services as a specific logistics project. Author characterizes the transportation service, with particular focus on …
Predictive Metabolic Suitability Maps for the Thermophilic Invasive Hydroid Pennaria disticha Under Future Warming Mediterranean Sea Scenarios
2022
Temperature is a fundamental variable for all biological processes. It influences the metabolism and tolerance limits of all living organisms, affecting species phenology and distribution patterns. It also facilitates the spread of non-indigenous species and the proliferation and expansion of native outbreak-forming species. Pennaria disticha is a colonial benthic cnidarian reported to be invasive in different Indian and Pacific coastal areas, as well as a harmful member of fouling communities found in Mediterranean marine aquaculture farms. Using the most basal functional trait (i.e., thermal tolerance), we explored the potential of P. disticha to colonize different habitats across the Med…
Study of the effects of climate extremes on functioning of intertidal assemblages to design an early warning sensor network

Development of an early warning system to predict sewer overflow
Flash flooding in our city is still a fairly common phenomenon.Unfortunately, the development of a flash flood forecasting system in urban areas is not a simple and unambiguous procedure.While attending the PhD course in Civil and Environmental Engineering, research activity has been given to realize an urban overflowing prediction system that was best as possible suited to the drainage network of the city of Palermo. With the support of radar data and hybrid hydraulic model for drainage network has been possible to demonstrate the effectiveness of this instrument, while the reduction of residual flood risk has been supported by modern resilience measures.
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…
Correlations between Reading Disabilities and Learning Disabilities
2015
The article is devoted to reveal correlations between reading disabilities and learning disabilities. These problems need to be explained and teachers need to have reasonable solutions. Number of school-children with learning disabilities is increasing and teacher is not able to find the best and most precise ways of diagnostics and treatment/intervention. Causes of learning disabilities are different: brain damage or distorted functioning of it; auditory or visual perception and operating problems; language acquisition or processing problems etc. Symptoms are mostly noticed in the main areas – reading, writing and mathematics. Reading disabilities are one of the most obvious and serious pr…
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…
