Design of realistic railway scenes in Unity HDRP with weather variations and camera angles. C# development of dynamic scenes including moving railway vehicles, animated workers, and simulated collision risks. Automatic generation of annotated data via Unity Perception to cover critical situations and dangerous construction site scenarios. Production of additional artificial images with the CIA Framework to greatly increase visual diversity (textures, poses, lighting). Training, optimization, and comparison of several object detection models on real, synthetic, generative, and mixed data. Evaluation of model robustness via precision, recall, and mAP. Demonstration of the value of a mix of artificial data to increase model reliability in real-world conditions.

Implementation and configuration of TCP/IP-based network topologies for performance studies in constrained environments. Simulation of routing protocols in Delay-Tolerant Networks using the ONE tool to evaluate intermittent transmission. Analysis of network behavior in the face of packet loss, high latency, and frequent connection drops. Comparison of protocols based on key metrics: end-to-end delay, delivery rate, resource consumption.

Redesign and improvement of the laboratory's website interfaces for better ergonomics and accessibility (HTML5, CSS3, JavaScript). Development of new features: management of scientific publications, addition of dynamic forms, and dedicated spaces for researchers. Server-side integration with PHP, ensuring secure communication with the database. Administration and optimization of the MySQL database: table normalization, query optimization, and user access management. Implementation of good security practices (data validation, session management, access rights).
