A source-destination based dynamic pricing scheme to optimize resource utilization in heterogeneous wireless networks
Published 2017“…To test the SDBDP scheme, we have developed an analytical model based on M/M/m/m queuing model. New or handoff service requests, arriving when all the RATs in the HWN are fully utilized, lead to call blocking for new calls and call dropping for handoff calls. …”

Using mathematical models to track phosphorus in a full-scale wastewater treatment plant
Published 2023“…These PI's were modified by De Ketele et al. (2018) and later extended by Coothen (2021) and they proved to be a useful approach to evaluating the environmental (EQI) and economic (OCI) impact of a WWTP based on any operational strategy implemented i.e., optimizing water resource recovery (WRRFs) and troubleshooting problems to improve our wastewater treatment systems in South Africa.…”
