This paper proposes a new cross-layer communication system for the provision of Internet services and applications to mitigate negative impacts COVID-19, due which massive online demands are affecting current systems’ infrastructures capabilities. The requirements model investigated where it utilizes high-altitude platform (HAP) fast efficient connectivity bridge infrastructure gap in pandemic....

3. Applicable Pollutants: Particulate Matter (PM), including particulate matter less than or equal to 10 micrometers (μm) in aerodynamic diameter (PM10), particulate matter less than or equal to 2.5 μm in aerodynamic diameter (PM2.5), and hazardous air pollutants (HAPs) that are in particulate form, such as most metals (except mercury is the notable exception, as a significant portion of emissi...

3. Applicable Pollutants: Submicron Particulate Matter (PM) greater than or equal to 0.3 micrometer (μm) in aerodynamic diameter, and PM greater than or equal to 0.12 μm in aerodynamic diameter that is chemically, biologically, or radioactively toxic; hazardous air pollutants (HAPs) that are in particulate form, such as most metals (mercury is the notable exception, as a significant portion of ...

Indoor exposure to PM 2.5 (particulate matter with aerodynamic diameter less than μm) has a substantial negative impact on people’s health. However, indoor can be controlled through effective ventilation and filtration. This study aimed develop smart control framework that (1) combines portable home air purifier (HAP) window system reduce concentrations whilst maintaining thermal comfort; (2) e...

Handoff algorithm is used in wireless cellular systems to decide when and to which base station (BS) to handoff in order that the services can be continued uninterrupted. In this paper, we propose a handoff algorithm based on the neural network in a joint system of terrestrial and high altitude platform station (HAPS) cellular systems. As a revolutionary wireless system, HAPS can supply service...

The U.S. Clean Air Act identifies 188 hazardous air pollutants (HAPs), or "air toxics," associated with adverse human health effects. Of these air toxics, 18 were targeted as the most important in a 10-City Pilot Study conducted in 2001 and 2002 as part of the National Air Toxics Trend Sites Program. In the present analysis, measurements available from monitoring networks in North America were ...

Glass-ionomer-cement (GIC) is helpful in Minimal Intervention Dentistry because it releases fluoride ions and is highly biocompatible. The aim of this study is to investigate the mechanisms by which hydroxyapatite (HAp) improves the mechanical strength and bioactive functioning of GIC when these materials are combined to make apatite ionomer cement (AIC). A conventional GIC powder was mixed wit...
