Ventilation and Humidity Control in Underground Utility Tunnel: an Under-Studied Topic

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Monitoring and control of underground ventilation systems using VUMA-network

Ventilation conditions in mines must be monitored to ensure safe and healthy conditions. However, the multiplicity of ventilation branches and equipment make it impractical to automate measurement of parameters all over a mine. It is more practical to monitor a few critical measurements that are fully reliable and extrapolate to ‘predict’ remaining conditions using ventilation network software....

Risk Assessment and Decision-Making under Uncertainty in Tunnel and Underground Engineering

The impact of uncertainty on risk assessment and decision-making is increasingly being prioritized, especially for large geotechnical projects such as tunnels, where uncertainty is often the main source of risk. Epistemic uncertainty, which can be reduced, is the focus of attention. In this study, the existing entropy-risk decision model is first discussed and analyzed, and its deficiencies are...

Application of fuzzy control to a road tunnel ventilation system

Tunnel ventilation control via an actor-critic algorithm employing nonparametric policy gradients

The appropriate operation of a tunnel ventilation system provides drivers passing through the tunnel with comfortable and safe driving conditions. Tunnel ventilation involves maintaining CO pollutant concentration and VI (visibility index) under an adequate level with operating highly energy-consuming facilities such as jet-fans. Therefore, it is significant to have an efficient operating algor...
