A Novel AI-Based Automated Identification of Cracks in Concrete Bridges and Offshore Oil Installations (ConcreteAI)

Environmental factors affecting concrete structures like bridges, beams, columns and highways in onshore and offshore environments lead to development of micro-cracks. Early detection of surface micro-cracks in concrete structures helps to put preventive measures in place to avoid failure potentially saving loss of assets and in some cases lives.

In this project scientists created an automated AI based system which will allow training and testing of real time images of concrete bridges and offshore structures, which are augmented by the presence of shadows and other noises. Researchers have worked hard on the development of an image database of images of concrete structures with cracks and shadows, which will then be used for training and testing of the AI network created specifically for this project.

Solitary solutions to stochastic COVID-19 pandemic models

The goal of the project is to find soliton solutions in stochastic models of the COVID-19 pandemic and to propose pandemic management methodologies based on the topological properties of these solutions. During the project, scientis improved the model of the COVID-19 pandemic by introducing diffuse and multiplicative relationships and adapting the model to the dynamics of Lithuanian diseases. The have also achieved important mathematical results which allowed a new look at the processes of the spread and control of pandemics.

The attitudes of parents and teachers towards the development of pre – school children ‘s health competence

The role of pre-school educators and parents and their mutual cooperation in developing children’s health competence and children’s health literacy are particularly important in the context of health literacy. The aim of the research was to determine the health literacy of pre-school teachers and parents according to the levels and their attitude to the development of health competence.
