Anti-Soiling Coating Technologies for PV Panels Under Dust Storm Conditions
Abstract: Background: Deployment of photovoltaics (PV) in arid and semi-arid areas where there is ample sunlight has been increasing quickly because of their high solar irradiation. The rising number of dust storms, as well as depositing particulate matter into the air, has caused a significant decrease in energy production due to reduced transmittance of light through the surface of the PV panel from the dust on the panel’s surface. This has …

Efficacy of Strain Wedge Method Against Traditional p-y Method for Analysis of Piles Subjected to Different Load and Soil Condition: A Review
Abstract: Pile foundation plays a major role in design of structures as its lateral response dominates the design subjected to lateral loads. These loads acting on foundations may be sustained from traffic loading on a bridge pier or earth pressure in a retaining wall. As soil reaction and pile deflection affect each other for a lateral load, this becomes a very complex soil-structure interaction problem. There are many approaches or methods …
