Anomaly-based online intrusion detection system as a sensor for cyber security situational awareness system
2016
Almost all the organisations and even individuals rely on complex structures of data networks and networked computer systems. That complex data ensemble, the cyber domain, provides great opportunities, but at the same time it offers many possible attack vectors that can be abused for cyber vandalism, cyber crime, cyber espionage or cyber terrorism. Those threats produce requirements for cyber security situational awareness and intrusion detection capability. This dissertation concentrates on research and development of anomaly-based network intrusion detection system as a sensor for a situational awareness system. In this dissertation, several models of intrusion detection systems are devel…
Reti sismiche urbane per monitoraggio sismico monitoraggio strutturale ed allerta precoce
2021
In questa tesi, viene effettuato un analisi preliminare in cui si mette in evidenza come l'italia sia un paese a rischio sismico, poichè possiede molti centri storici con strutture non progettate per eventi sismici di media entità. Si è prestato molta attenzione su quante vite umane vengono salvate dopo un terremoto catastrofico. L'analisi fa emergere come, è importante essere tempestivi nell'estrarre le persone rimaste sotto le macerie, poichè la percentuale di persone estratte vive si mantiene alta solo entro le 48 ore dall'evento. Dopo 96 ore questa percentule si attesta a 0. In eventi passati spesso i soccorsi sono arrivati con giorni di ritardo nelle zone più devastate. L'obbiettivo ch…

Early warning thresholds for partially saturated slopes in volcanic ashes
2013
Rainfall-induced landslides in steep soil slopes of volcanic origin are a major threat to human lives and infrastructure. In the context of constructing early warning systems in regions where extensive data on landslide occurrences and associated rainfall are inexistent, physically-based tools offer the possibility to establish thresholds for measurable field quantities. In this paper, a combined finite element infinite slope model is presented to study the transient hydraulic response of volcanic ash slopes to a series of rainfall events and to estimate seasonal safety factors. Furthermore, analytical considerations of partially saturated infinite slopes are made to define capillary stress…
Overvåking av vitale parametere i sykehus : En sammenligning av manuelle og elektroniske overvåkingssystemer
2018
Masteroppgave i helse- og sosialinformatikk HSI500 - Universitetet i Agder 2018 Adverse events can be avoided by timely recognition of derangements in vital signs. Sørlandet Hospital HF (SSHF) has implemented an Early Warning Score System named "TILT"; 2Early identification of life-threatening conditions”. In 2017 SSHF started a project that tested wireless sensors for continuous monitoring of vital signs on wards. Patients were monitored by sensors and vital signs were also measured by traditional means during the project period. The aim of this study was to examine compliance with the vital signs monitoring protocol, and to examine the benefits of an electronic system. The following quest…
Early warning system in logistics project management
2017
Risk management is a vital process in all complex logistics project management. We discuss the concept of early warning system EWS dedicated to logistics project, which enable management under the conditions of uncertainty and risk. The complexity and uniqueness of the logistics projects as well as the discontinuity of the effects in the environment of goods and services, significantly impact the inability to eliminate the risks and subsequently lead to changes during execution. The introduction into companies and supply chains things such as: principles, methods, mechanisms of knowledge management and project risk, e.g. by implementing into the logistics project management the early warnin…
Stakeholder Analysis as a Source of Early Warning Signals in Logistics Projects
2017
Logistics projects are undertaken by a set of multiple organizations that engage resources from different logistics systems, production systems, management systems, social-cultural systems. They are subject to impact of wider economic and political environments. Logistics projects involve participants from diverse cultural environments, management practice. The article presents the essence and importance of stakeholders in projects including logistics projects. The author presents the basic issues related to stakeholders and early warning concept in project management. The specific research question is: How to implement the stakeholder relations management in early warning system dedicated …
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…
