5G-NR PRACH Detection Using an AutoEncoder Under Interference
Ahmed Sawadogo, Désiré Guel, Boureima Zerbo
Efficient detection of the Physical Random Access Channel (PRACH) is vital for reliable initial access in 5G New Radio (5G-NR), yet it remains challenged by intra- and inter-cell interference. This paper proposes a deep learning-based solution leveraging an Autoencoder (AE) trained on synthetic PRACH data under noisy conditions. The model dete(...)

Recommendation Generation Justified for Information Access Assistance Service (IAAS): Study of Architectural Approaches and Post-Hoc Algorithm
Kabore, K. , Kyelem, Y. and Ouedraogo, T.
Recommendation systems only provide more specific recommendations to users. They do not consider giving a justification for the recommendation. However, the justification for the recommendation allows the user to make the decision whether or not to accept the recommendation. It also improves user satisfaction and the relevance of the recommend(...)

Ouagadougou SUMO traffic scenarios for urban mobility.
Emile NANA, Ferdinand Tonguim GUINKO
In our work, we are attempting to predict urban traffic congestion in order to address issues related to urban mobility. We believe that congestion situations have upstream causes that significantly impact urban traffic flow. Thus, to resolve the problem of traffic congestion, there are intermediate steps that allow us to understand the traffi(...)

Numerical Assessment of Hydrodynamic Trends on Dam Stability, and Groundwater Prediction in the Bagré Dam, Burkina Faso: Implications for Climate Change
Triumph Prosper Orowale1 Seyni Salack2 Youssouf Koussoube1 Moussa Guira3 Issoufou Yangouliba2 Rajesh Gudihalli Munivenkatappa
In the context of climate change and the subsequent pressure from geological structures, there is a pressing need to analyse hydroclimatic trend events on dam stability and establish a clear correlation between reservoir surface water and groundwater levels in the Bagré Dam. Hydrodynamic variables (evaporation, inflow, irrigation, spillage, wa(...)
