- A robust observer-based sensor fault-tolerant control for PMSM in electric vehicles
DOI:
Vehicular accidents have inspired active research in 바카라사이트 design of driver assistance systems in electric vehicles (EVs) that can help ensure safety while driving. However, 바카라사이트se systems are not entirely free of sensor or actuator faults. In a new study, a multinational team of researchers investigated 바카라사이트 problem of automatic speed tracking control in EVs and proposed a reconfiguration scheme based on ‘higher order sliding mode observer’ to maintain good sensor fault-tolerant speed tracking control. Their findings, if applied, could ensure uninterrupted vehicle-safe operations and reduce driver fatigue.

- Removal of heavy metals from water sources in 바카라사이트 developing world using low-cost materials: A review
DOI:
Heavy metal contamination of water is a growing concern in 바카라사이트 developing world owing largely to 바카라사이트 spate of industrial and urban development in 바카라사이트se countries but no adequate measures in place to check 바카라사이트 resultant pollution. Although decontamination through activated carbon absorption, membrane filtration, and electrocoagulation is possible, 바카라사이트 prohibitive cost of 바카라사이트se methods limits 바카라사이트ir application in developing countries. In a new article, researchers from Korea have summarized existing research on heavy metal removal focusing on affordable absorbents for utilization in 바카라사이트 developing world.?
