About Me

I have a diverse background, holding a Bachelor’s degree in Aeronautical Engineering, an MSc in Data Science and Analytics, and currently pursuing a PhD in Computer Science. My professional journey has led me to gain experience in various industries, including aviation safety, underground mining maintenance, reliability, and software development.

Publications

Benjumea, D. C., Laniado, H., & Combita, O. (2023). Analytical model to monitor the oil conditions on the main components of mining dumpers. Results in Engineering, 100934. Link

A good reference for engineers who intend to understand oil data and promote the development of lifetime models of components. The paper studies lifetime expectation of the main components of dumpers considering oil data. These lifetimes were analyzed by using the Cox proportional hazard model and a new robust version of the same model that is the main contribution of this work. The results show that robust version introduced has better performance than Cox classical model.

PhD Thesis

Autonomous Robotic Rules Based Reasoning System for use in UK Nuclear Environments
In the UK, the nuclear regulatory regime requires a safety claim to be argued and substantiated for any activity. However, existing techniques for assuring the behaviour of autonomous robotics systems, that are efficient to use regularly, are not robust enough for use in nuclear environments. The proposed research aims to develop a methodology for creating and verifying Safety Instrumented Functions (SIFs) using rule-based reasoning system technology that is well-understood and amenable to mathematical verification. The methodology will involve the use of tools to capture safety requirements expressed in natural language and convert these into expressions into temporal logic, and then the use of model-checking technology to verify the SIF against these requirements. The SIF will then interact with the Autonomous Robotic system to constrain its behaviour to a safe envelope. This will be validated with a demonstration based on a use case of an inspection task with safety requirements based on avoiding collisions between the robot and its environment.
