Prevention of PM2.5 is attracting increasing attention all over the world as can cause and exacerbate respiratory diseases. Compared with conventional natural ventilation mechanical ventilation, air purifiers particular filters are more efficient in control indoor PM2.5. Currently, there limited studies on operations portable purifiers. To improve efficiency an purifier PM2.5, optimal operation...

In this paper, we present the design and evaluation of a prototype Autonomous Water Purifier (AWP) for removing heavy metals from contaminated water. The AWP uses solar energy its operation; autonomous photovoltaic system is designed to operate up 8 hours per day generate water flow 112 liters day. was remove biological chemical agents. It achieved elimination total coliforms, fecal alkalinity,...

A huge amount of data is produced in every domain these days. Thus for applying automation on any dataset, the appropriately trained plays an important role achieving efficient and accurate results. According to researchers, scientists spare 80% their time preparing organizing data. To overcome this tedious task, IBM Research has developed a Data Quality AI tool, which varieties metrics that ca...

Indoor air pollutant sources are crucial in assessing IAQ, especially when outdoor concentrations low. In the present study, PM mass a range of five sizes; CO, CO2, O3, NO, NO2, and TVOC concentrations; along with temperature relative humidity were monitored three indoor locations university. The monitoring took place building dedicated to teaching undergraduates. first two locations, professor...
