BACKGROUND Forced-air warming (FAW) is widely used to prevent hypothermia during surgical procedures. The airflow from these blowers is often vented near the operative site and should be free of contaminants to minimize the risk of surgical site infection. Popular FAW blowers contain a 0.2-μm rated intake filter to reduce these risks. However, there is little evidence that the efficiency of the...

This study developed a reinforcement learning-based energy management agent that controls the fine dust concentration by controlling facilities such as blowers and air conditioners to efficiently manage in station. To this end, we formulated an optimization problem based on Markov decision-making process model for predicting of station training artificial neural network (ANN) supervised learnin...

In automobiles, the demand for HVAC has been rising decades and key variables that affect thermal comfort in a car were identified as air velocity, temperature, radiant relative humidity. Thermal estimation vehicle depends on transient behavior of cabin space boundaries. The predicted mean vote (PMV) percentage dissatisfied (PPD) are available methods to describe optimize space. this paper, min...
