Fast, vision-based, line-following schemes for Micro Aerial Vehicles in nuclear environments (2019)
Presentation / Conference
Nemati, H., Goki, S. H. M., Yazdanshenas, A., & Taylor, C. J. (2019, October). Fast, vision-based, line-following schemes for Micro Aerial Vehicles in nuclear environments. Paper presented at 2019 IEEE Nuclear Science Symposium and Medical Imaging Conference, Manchester Central Convention Centre, Manchester, United Kingdom

Many nuclear power plants are reaching the end of their economic lifetime and the decommissioning of legacy nuclear facilities is an important challenge in the next few decades. Since the radiation level in these facilities is significant, autonomous... Read More about Fast, vision-based, line-following schemes for Micro Aerial Vehicles in nuclear environments.

A fuzzy data-driven paradigmatic predictor (2019)
Journal Article
Amirjavid, F., Nemati, H., & Barak, S. (2019). A fuzzy data-driven paradigmatic predictor. IFAC-PapersOnLine, 52(13), 2366-2371. https://doi.org/10.1016/j.ifacol.2019.11.560

Data-driven prediction of future events is to provide decision-makers Predictive Information (PI) to decrease human-error. They usually desire possession of a predictor which works independently from the humanized configurations and works efficiently... Read More about A fuzzy data-driven paradigmatic predictor.

A fuzzy paradigmatic clustering algorithm (2019)
Journal Article
Amirjavid, F., Barak, S., & Nemati, H. (2019). A fuzzy paradigmatic clustering algorithm. IFAC-PapersOnLine, 52(13), 2360-2365. https://doi.org/10.1016/j.ifacol.2019.11.559

Clustering algorithms resume the datasets into few number of data points such as centroids or medoids, which explain the entire dataset briefly. In the domain of data-driven machine learning, the more precision with the clustering rule leads directly... Read More about A fuzzy paradigmatic clustering algorithm.
