“…While all the three projects we explored require positioning of people or vehicles, ALARP has severe requirements in terms of localization accuracy of workers. Low-cost GPS receivers are not sufficiently accurate to reliably identify if a worker is in a red or a green zone, as it was measured in [61]. A GPS-augmentation approach has been devised in ALARP, and it is presented and evaluated in [18].…”

Abstract-A dramatic shift in system complexity is occurring, bringing monolithic system designs to be progressively replaced by modular approaches. In the latest years this trend has been emphasized by the System of Systems (SoS) concept, in which a complex system or application is the result of the integration of many independent, autonomous Constituent Systems (CS), brought together in order to satisfy a global goal under certain rules of engagement. The overall behavior of the SoS, emerging from such complex interactions and dependencies, poses several threats in terms of dependability, timeliness and security, due to the challenging operating and environmental conditions caused by mobility, wireless connectivity, and the use of off-the-shelf components. Referring to our experience in mobile safety-critical applications gained from three different research projects, in this paper we illustrate the challenges and benefits posed by the adoption of an SoS approach in designing, developing and maintaining mobile safety-critical applications, and we report on some possible solutions.

“…We choose the same δ for each scenario to show how the same sensitivity is suitable in a scenario and needs of a different tuning in another, although a detailed sensitivity analysis of the parameters α, δ is outside of the scope of this paper and will be performed as future work. Due to the geographical dimension of the considered areas, localization uncertainty of the events, which may be up to several meters [29], is not significant for our analysis and consequently not considered in this work.…”

Abstract-The large availability of smart portable devices and the growing interest in developing Internet of Things (IoT) oriented software components make several heterogeneous data available for analysis purposes. In the context of Crisis Management Systems, this means that people owning mobile devices when involved in natural disasters or terroristic attacks may be considered information sources as the classical ones, e.g., sensors or surveillance cameras. Including the information from the citizens in the situational analysis processes comes with two main issues that need to be addressed: i) the source could deliver wrong data (voluntarily or by mistake) that damage the integrity and the correctness of the analysis, and ii) a significant amount of heterogeneous data need to be selected, filtered and aggregated, to provide to the operator a real-time snapshot of the situation depicted using only credible and relevant information. In this paper, we define and implement a relevance labeling strategy able to process information coming from heterogeneous sources aimed at crisis situations and to provide to the human operator all the details he needs. We include provisions for detecting and removing redundancies and misleading data that can slow down or compromise the process and the a-posteriori analysis. The filtering strategy is last applied to events collected for the Secure! crisis management service-based system, showing its application to three scenarios related to real crisis situations happened in the last year.

“…Therefore, the extensive use of permanent GPS stations (e. g. RING network, Rete Integrata Nazionale GPS, consists of about 150 stations [3]) and non-permanent GPS stations [4], routinely operating for geodetic purposes and, even offers a "non-geodetic" tool aimed at a dense and reliable remote sensing of atmospheric water vapour.…”

Precipitable water (PW) derived from the CDGPS (Continuous Differential Global Positioning System) zenith tropospheric delay (ZTD) is evaluated through comparison of three procedures: using GPT (Global Pressure and Temperature) and GPT2 global models as well as observed data. The results show that the difference between PW retrieved from models (GPT and GPT2) and PW obtained by observed meteorological data, at least for sites and period observed in this paper, is also a function of the position of the station. The short period considered does not allow for any consideration of possible intra-annual or annual periodicity. The analysis of the residuals between observed PW and modeled PW shows a peak before the rain event.
