Multi-Channel Audio CODEC with Channel Interference Suppression
A multi-channel audio CODEC with interchannel interference suppression is proposed, in which channel switching noise-referred sampling error is significantly reduced when all the channels are running independently. Expand
NOx Emission Characteristics Depending on the Variations in Yaw Angle of the Secondary Air Nozzles in a Coal Fired Boiler
Three dimensional numerical analysis for the coal fired boiler has been performed to investigate the effect of yaw angle variation of the secondary air nozzles on the combustion characteristics andExpand
Selection of Valves Susceptible to Pressure Locking and Thermal Binding
Some gate valves are susceptible to pressure locking and thermal binding which prevent the safety function. The safety related gate valves susceptible to pressure locking and thermal binding shall beExpand
