An air distribution system for use with a wind turbine. The wind turbine includes a nacelle that is coupled to a tower and a rotor that is rotatably coupled to the nacelle with a rotor shaft. The rotor includes at least one rotor blade that is coupled to a hub. The air distribution system includes a conduit that is defined within the rotor shaft. The conduit provides flow communication between the nacelle and the rotor. An air-flow control assembly is coupled in flow communication with the conduit. The air-flow control assembly is configured to selectively channel air from the nacelle to the rotor and from the nacelle to ambient air.

Microfluidic devices are described that include a rigid base layer, and an elastomeric layer on the base layer. The elastomeric layer may include at least part of a fluid channel for transporting a liquid reagent, and a vent channel that accepts gas diffusing through the elastomeric layer from the flow channel and vents it out of the elastomeric layer. The devices may also include a mixing chamber fluidly connected to the fluid channel, and a control channel overlapping with a deflectable membrane that defines a portion of the flow channel, where the control channel may be operable to change a rate at which the liquid reagent flows through the fluid channel. The devices may further include a rigid plastic layer on the elastomeric layer.

A code stream conversion system and method, a code stream identifying unit and a solution determining unit are provided. The code stream conversion method includes: receiving an original code stream format obtained by parsing an original code stream; and determining a transcoding solution according to a target code stream format and the original code stream format, and using the original code stream format to decode the original code stream and using the target code stream format to encode a decoded code stream according to the transcoding solution, thus completing code stream conversion, and obtaining a target code stream corresponding to the target code stream format. Through the code stream conversion system and method, the original code stream is parsed and the transcoding solution is determined, thus achieving mutual conversion between a three-dimensional video code stream and a planar video code stream.

A rotor blade for a wind turbine is disclosed. The rotor blade includes a root, a tip, and a body extending from the root, the body including a pressure side and a suction side extending between a leading edge and a trailing edge. The rotor blade further includes a winglet extending between the body and the tip, the winglet including a pressure side and a suction side extending between a leading edge and a trailing edge. The winglet further includes a transition section and defines a height, a sweep angle, an outboard cant angle, and a twist angle. The sweep angle, the outboard cant angle, and the twist angle change continuously throughout the transition section.

The invention provides a method of efficiently producing branched, cyclic glycerol-based polyols with a co-product as anti-biodegrading agent from inexpensive readily available glycerol monomer. The method involves polymerizing glycerol or glycerol with at least another monomer to multiple other monomers in the presence of particular amount of a strong base as the catalyst under a particular distillation environment. The polyol produced by the inventive method is beneficial of reducing scales in Bayer liquid for aluminum production process and improving brightness of coated paper substrates without greening effect.

A method and device for controlling a code rate are provided, and this application relates to a video communication technology. The method for controlling a code rate includes the following steps. An output target bit of a current frame is acquired, where the current frame is a currently processed input frame. A target quantization parameter is acquired according to the output target bit by utilizing a nonlinear code rate control model. The present invention is applicable to transcoding between compressed videos.
