OPEC and non-OPEC countries aim to agree a framework for long-term cooperation by December.

The paper has given an overview of different power electronic converters in WTSs with special attention paid to the many possible topologies at low voltage and medium voltage. An important trend is that the technology is moving toward a higher power level. and it is inevitable that it goes for …

This paper has presented a mean shift-based machine vision method for detecting fingerprint and contamination defects in multicrystalline solar wafers. The defect types involve random gradient directions. whereas the normal grain edges generally present more consistent gradient directions in a small spatial window. The entropy of gradient directions is then …

The fault diagnosis of wind converter is in continuous development in recent years. It reduces the downtime and maintenance cost of WECS. and improves the system availability and operational safety. This paper has surveyed typical fault modes of the fragile components in wind converter and has provided a comprehensive review …

The U.S.-China trade tension restricts oil from rising further.

We have investigated the impact of TDD on the performance of 1J n+ p GaAs and 2J n+ p InGaP GaAs cells on Si at AM 1.5G spectrum. The analysis indicates that in a 1J GaAs cell on Si with a 2.5-μm-thick GaAs base. an efficiency of greater than 23% …

Japanese oil distributors are set to halt oil imports from Iran in light of the U.S. request.
