Pickering asphalt-water emulsions stabilized by polystyrene nanoparticles obtained from recycled material
Abstract: In recent years, emulsified asphalt has been found to offer numerous advantages over conventional asphalt. More recently still, emulsified asphalt stabilized with nanoparticles has emerged as an option for the construction field because this substance has many advantages over traditional emulsified asphalt, which is formulated with surfactants that tend to be less stable and more toxic. These new formulations are called Pickering emulsions. They can align with basic sustainability principles. …

Adaptive Selective Harmonic Elimination Method for Quasi Z-Source Cascaded Multilevel Inverters in Varying DC Voltage Condition
Abstract: AbstractIn this paper, a new control method for adaptive selective harmonic elimination in a quasi Z-source cascaded multilevel inverter (QZS-CMI) is proposed. According to real condition, the DC sources feeding the inverter are considered to be varying in time. In this condition, the switching angle and shoot-through duty ratio for each module are obtained off-line for different DC source values using particle swarm optimization (PSO) algorithm. The off-line data set …
