MODELLING AND CONTROL OF COMBUSTION PHASING OF AN RCCI ENGINE

, 2020
Reactivity controlled compression ignition (RCCI) is a novel combustion strategy introduced to achieve near-zero NOx and soot emissions while maintaining diesel-like efficiencies. Meanwhile, precise control of combustion phasing is a key in realization of high fuel conversion efficiency as well as meeting stringent emission standards.

Enhancing Public Safety in Eswatini: A Machine Learning–Driven Predictive Policing Model

Human Behavior and Emerging Technologies, Volume 2025, Issue 1, 2025.
Public safety remains a critical concern in Eswatini, as it prevents crime, reduces delayed response mechanisms, and optimizes police resources. This study applied machine learning techniques in predictive policing within the Kingdom of Eswatini (formerly Swaziland) to improve proactive law enforcement strategies and public safety.

Machine Learning–Based Prediction and Analysis of Engine Performance for a Direct‐Port Injection Compressed Natural Gas Fueled Engine

Journal of Combustion, Volume 2025, Issue 1, 2025.
Compressed natural gas (CNG) is one of the most potential alternative fuels for internal combustion engines (ICEs). Investigation of injection strategies is crucial to improve CNG engine performance and extend flammability limit, especially for direct‐port combined injection (DI‐PI) CNG engine.
