QRIS: a QuaDRiGa-Based Simulation Platform for Reconfigurable Intelligent Surfaces
IEEE Access. 2023. Vol. 11. P. 90670–90682.
Reconfigurable Intelligent Surfaces (RISs) are a promising way to improve the performance of wireless networks. However, despite the high interest in the research community, no flexible enough simulation platform allows studying the performance of wireless communication systems with RIS in complex scenarios. To address this issue, the paper presents an open-source channel simulation platform to study RIS in wireless communication systems. The developed open-source platform extends the QuaDRiGa channel model, which is widely used for the performance evaluation of 5G and Wi-Fi networks with multiple antennas. The paper shows how to use the platform—called QRIS—to evaluate RIS in various frequency conditions, such as indoor/outdoor scenarios and multiple-RIS deployments.

In process mining, DFG (Directly-Follows Graph) models are popular due to their simplicity and clarity. However, if a process is acyclic but contains concurrent events, standard algorithms for discovering DFG models can generate "fake" cycles that do not actually exist in the event log. These cycles hinder the analysis of information processes, significantly reducing the ...

Object-centric process mining has emerged as a powerful paradigm for analyzing event data involving multiple interacting business objects. Existing discovery techniques often rely on object-centric Petri nets with fixed arc multiplicities, limiting their ability to represent parametric resource consumption and production patterns and to capture quantitative dependencies between interacting object types. In this paper, we ...

Recent advances in large language model (LLM) agents have shown promise for autonomous decision-making in recommender systems. However, existing approaches suffer from two fundamental limitations: flat agent memories that conflate different information modalities and prohibitive computational costs that prevent scaling beyond a few hundred users. We propose Hybrid-GraphRAG, a recommender system that integrates hierarchical agent ...
