We describe a concept for circuit protection and fault current limitation in DC power systems based on the use of solid-state power switches. The approach could be useful in the increasingly widespread application of DC power distribution networks. During normal operation the power switch is always “on”. During faults, the gate of the solid-state switch is pulse modulated to prevent the circuit...
In irrigation scheduling, one question is “how much is the optimal depth?”. In this study the optimal irrigation depth (by assuming the power distribution function and by taking into consideration the distribution function, which governs the data (normal distribution)) by considering the environmental effects was determined for three water management strategies (i. e. unlimited, limited nitroge...

Slope ecological protection technology is a form of slope with high ornamental and good economic value. At present, it widely used in highways urban streets’ works. However, its use not very common mountain tourism highways; hence, necessary to implement strategies for highway design promote excellent development.
Forty-six ancient Tibetan star-shaped towers and a village are located on a giant slope, which would be partially flooded by a nearby reservoir currently under construction. Ground survey, boreholes, and geophysical investigations have been carried out, with results indicating that the slope consists of loose deposit with a mean thickness of approximately 80 m in addition to an overlying bedroc...
The visco-elastic properties of asphaltic layers make it appropriate for application in coastal protection in embankments. In this research, an experimental set up of a coastal embankment is developed to investigate the characteristics of lean stone asphalt layer on coastal embankments. More than 100 laboratory tests were carried out considering various loading conditions on the asphalt protect...
