Abstract |
This paper presents a unique view of modeling the diffusion of warnings in social networks where the network structure may change over time. Since the characteristics and actions of people in a community have significant influence on the flow of information through a network, we present an axiomatic framework for modeling the diffusion process through the concept of trust. This ongoing work provides a micro level view of the behavior of individuals and groups in a community. Preliminary experiments were made to explore how model parameters such as trust and the social network structure affect warning message belief and evacuation. |

Abstract |
This paper describes MOIA, a numerical tool that evaluates sea-wave effects on port operations and broadcasts warning messages whenever the safety of such operations are deemed to be at risk. The evaluation of the sea-wave transformation from offshore – where the results of numerical models for sea-wave forecast at a regional level are available – up to the port area is described. Also, the procedures used to evaluate the sea-wave effects on sailing ships, focusing on the amplitude of the vertical movements of a selected point in the ship, are explained. Such procedures are combined and applied to an example where the average downtime for the navigation at four points along the sailing lane is evaluated for the entrance voyages into the port of Praia da Vitória (Azores) of a given ship. |

Abstract |
This paper reports the progress that is being made in developing a software tool (the Flood Warning Communicator, FWC) that helps communication professionals constructing effective flood-warning messages. The program provides authorities with a warning message that contains open spaces where event specific information can be inserted. The program uses a database containing (parts of) phrases. Based on the specific situation, a communication professional receives the most suitable standard phrase by clicking on information buttons in a user interface. Together, the phrases form the warning message that sometimes requires minor adjustments such that it suits the specific circumstances. FWC is a well working prototype that allows constructing messages for web sites and short text messages (sms). Research is needed to test and validate these warning messages. In addition, cooperation with public authorities is necessary to make the program suitable for local circumstances (e.g., safety regions and municipalities). |
