The main objectif of this paper is to present a tool that we have developed subject to characterize and modelling indoor radio channel propagation at millimetric wave. The tool is based on the ray tracing technique (RTT). As, in realistic environment we cannot neglect the significant impact of Human Body Shadowing and other objects in motion on indoor 60 GHz propagation channel. Hence, our prop...

Overview In the 1998-99 school year, U.S. K-12 public schools provided instruction to over 46 million students. An estimated 70% of all school buildings have indoor air quality (IAQ) problems, leading to an unhealthy environment. Because children breathe a greater volume of air relative to their body weight compared to adults, they may be more sensitive to indoor air pollution. Additionally, oc...

Mushroom factory is an emerging production mode that relied on facility and equipment by creating a suitable, steady, uniform growing environment to accommodate the demand of edible fungus at each stage growth. Therefore, optimal range key environmental factors (temperature, humidity, light, CO2 concentrations) in mushroom facilities crucial achieving satisfactory rates. This research aimed pro...
