In China, More than 458 cities and more than 50% of the population are distributed in natural disaster-prone areas. It is important to establish a complete post-disaster reconstruction and rehabilitation system to respond to sudden natural disasters. In order to get post-disaster restoration items scheduling, we invited experts to give the fuzzy preference relation coefficients on the restoration...
China is one of the countries which is often affected by kinds of natural disasters. In China, More than 458 cities and more than 50% of the population are distributed in natural disaster-prone areas. As a developing country, China should take this as a warning. It is important to establish a complete post-disaster reconstruction and rehabilitation system to respond to sudden natural disasters. In...
A high power 10 kV IMD (induction motor drives) system supplied by a 6 kV three-level NPC (neutral point clamped) inverter with IGCTs (integrated gate commutated thyristors) in series connection, which applied in water works has been developed and achieved. The designed three-level inverter system includes a 24 pulses rectifier, a diode NPC three-level medium voltage VSI (voltage source inverter)...
Superellipses can be used to represent in a compact form a large variety of shapes, and are useful for modelling in the fields of computer graphics and computer vision. However, fitting them to data is difficult and computationally expensive. Moreover, when only partial data is available the parameter estimates become unreliable. This paper attempts to improve the process of fitting to partial data...
