The Covid-19 pandemic has posed new challenges for both students and teachers, having to move from face-to-face to online teaching in a short time. The threats brought new opportunities, allowing students away from schools due to limitations, to use on-line classes for developing their careers and academic skills. Designing an inclusive course for...

Cloud Computing has changed the paradigm of traditional computing, freeing end users and companies from having their own computing resources. Instead, users have access to seemingly unlimited resources, with great availability and reliability, in a transparent and ubiquitous way, using thin clients through the internet. In this article, the NIST Cl...

Behavioural modelling is a new branch of Artificial Intelligence as well as Modelling and Simulation, lacking knowledge about the human decision-making process, which is not always obvious or rational, but dependent of emotions. When addressing the specific field of emergency situations and preparedness, for instance, when facing a fire, there is h...

To...
Conference Paper
Full-text available
Evacuation planning as part of fire safety management, is mandatory in Portugal for new and existing buildings. Estimating the egress time is paramount for the development of emergency evacuation plans. For this estimation, fire drills are undertaken. However, carrying out fire drills demands a certain amount of time and financial resources. In add...

Conference Paper
Full-text available
This paper focuses on an approach to dynamic planning, for an emergency ambient such as team rescue in indoors fire. First a graph is generated as the simulation runs, creating an effect similar to means-end analysis as each fire trying to reach the firefighter. This graph is updated in real time, improving the solution performance and reacting to...
Thesis
Full-text available
This thesis proposes the use of Serious Games as a behaviour elicitation tool in addition to the traditional methods such as direct observations or stated-preference questionnaires. The resulting knowledge is needed to improve behavioural models of intelligent agents mimicking pedestrians. From the literature review and subsequent gap analysis, a m...
Article
The problem of leaving a building while facing some emergency has gained much attention from the scientific community. Evacuation simulators can help emergency planners to assess the safety of buildings. However, such simulators still lack behavioural knowledge to increase their accuracy. The elderly have specific behaviour idiosyncrasies. This pap...
Chapter
Crowded spaces are prone to accidents and many casualties in case of fire or other emergency situations. They can happen in large buildings or urban spaces. Predicting crowds’ behavior is crucial for creating adequate simulators that practitioners can use for evaluating evacuation scenarios in such emergency cases. On the basis of a literature revi...

Fire risk is the leading hazard for the safety of buildings', not only due to potential, but also concerning property/value losses. When it comes to cultural heritage, fire is by far the most destructive phenomena, and prevention is the most effective way of protection. Portugal's current fire code published in 2008, establishes the need of self pr...

The dynamics of pedestrians have received less attention in transportation systems when compared to cars and other transportation means. However, its importance is inarguable and, recently, a lot of effort on research was put into this field. The use of Agent-Based Models (ABM) and known techniques such as the Social Forces Model (SFM) has fostered...

Serious Games have fostered the training methods and are increasingly used for such purposes. A fire in a public building, such as a hospital, care centre or clinic, is by any point of view a dramatic event. Emergency planning is crucial to prevent and minimize damage and victims. Despite the improvement on safety measures, many occupants and emplo...

Issues related to crowd evacuations have become extremely important and gained the attention both of practitioners and public authorities. Un-derstanding the dynamics and the emerging behaviour of the crowd during evacuation is a challenge under any circumstances.
