in recent years, there has been a fast growth in wind energy conversion system (wecs). there are two general types of wind turbines in wecs: fixed speed wind turbines and varying speed wind turbines.permanent magnet synchronous generator (pmsg) is one of the most attractive generators for the varying speed turbine wecs.in this paper, a fuzzy controller is proposed to control the current source ...

Because the power systemload the randomness of the nature, power transmission of AC induction system has the low efficiency. In order to improve the transmission efficiency,the transmission efficiency influenced factors of the system is analyzed. Based on the current source power transfer system, DC/DC circuit for dynamic adjustment method is proposed. The method ensures that the transmission e...

Climate change has been a thorny issue in the context of China becoming “carbon neutral”.It is important to mitigate negative effect and potential side climate stable economic growth. Green finance crucial measure address issue. This paper reviews current state research on impact growth application green mitigation. Hence, finding out method mitigation strategy further application.

The current state of the art virtual characters fall far short of characters produced by skilled animators. One reason for this is that the physical behaviors of virtual characters do not express the emotions and attitudes of the character adequately. A key deficiency possessed by virtual characters is that their gaze behavior is not emotionally expressive. This paper describes work on expressi...

Many experts encourage homeowners to improve their houses to better survive natural catastrophes and reduce overall societal costs. However, we find these encouragements are not necessarily financially sound for the homeowner at risk of hurricane wind damage. We find that subsidized insurance reduces the incentive for a risk-neutral homeowner to purchase structural mitigation, as mitigation doe...
