Oauth2.0 In Securing Apis, Olimpion Shurdi, Aleksander Biberaj, Igli Tafa, Genci Mesi

UBT International Conference

Today’s modern applications are mostly designed around API’s. API’s are used for a variety of things such as passing data to another webservice reading data from a database etc. The problem with this is that not all the API’s are secure. Most of the today’s API’s are old and rely only on an authentication token where the user data often had to share their credentials with the application to enable such an API call on their behalf or string them, which is often hardcoded. We will focus on OAUTH 2.0 as new protocol in securing our API’s. This is a …

A Hybrid Agent-Based And Equation Based Model For The Spread Of Infectious Diseases, Elizabeth Hunter, Brian Mac Namee, John D. Kelleher

Articles

Both agent-based models and equation-based models can be used to model the spread of an infectious disease. Equation-based models have been shown to capture the overall dynamics of a disease outbreak while agent-based models are able to capture heterogeneous characteristics of agents that drive the spread of an outbreak. However, agent-based models are computationally intensive. To capture the advantages of both the equation-based and agent-based models, we create a hybrid model where the disease component of the hybrid model switches between agent-based and equation-based. The switch is determined using the number of agents infected. We first test the model at …
