LIAM-ADERSIM Agent-based Simulator for the Gastro-intestinal Pathway of L. monocytogenes

Project Summary:

Understanding the key mechanism of step-by-step transitions of the food-pathogen L. monocytogenes within a host is significantly important for risk evaluation and reduction. This project will develop an agent-based simulator to imitate the gastro-intestinal pathway of L. monocytogenes. The biological factors such as pH variation, digestion process, stomach emptying time and pathogen factors such as survival fitness will be added to the features of the simulator. The simulator will consider the effect of food-matrix such as liquidness and fat concetration in the survival of pathogen. The effect of food intake time and randomness of pathogen distribution in the food portions will be also taken into consideration. The simulator featured by the key physiological processes will account for the pathogen survivability in the gastro-intestinal tract of human hosts.

Developing a fire response simulation test bench based on NFID

Project summary:

This research project was initiated to develop a simulation engine leveraging the National Fire Information Database (NFID) in order to provide fire departments across Canada with a data driven tool for evidence-based planning and response to fire incidents, thereby helping them create safer communities.

Fires and Disasters: Examining Fire Incidents during Major Disasters and Emergencies in Canada

Canadian cities, towns, municipalities, regions, and provinces experience various types of major disaster and emergencies. Major disasters and emergencies are not just bigger than everyday emergencies that fire departments normally respond to them. They can quickly overwhelm fire departments. They may require the application of different performance standards and protocols. While fire departments are proficient at planning and preparing for normal operating conditions and some of them have great experiences with large emergencies, better understanding and preparedness for disaster events is more challenging. Knowledge of the expected situations and preparedness lead to better fire response during such events. Understanding the nature, volume, characteristics and response performances of fire departments during major disasters and emergencies is very important. This study aims to provide some insights into the patterns and characteristics of fire incidents during major disaster and emergencies in Canada using the National Fire Incident Database (NFID).
