Abstract The use of aero-elastically tailored blades (ATB) for large wind turbines has shown the benefit mitigating blade loads, in a passive adaptive manner, with design bend-twist coupling (BTC) along blades. BTC makes torsionally flexible and capable adapting to different speeds. However, such increased flexibility turbine modeling computationally demanding real-time controller more challeng...
Low contrast images, suffering from a lack of sharpness, are easily influenced by noise. As a result, many local false peaks may be generated in contrast measurements, making it difficult for the camera's passive auto-focus system to perform its function of locating the focused peak. In this paper, a new passive auto-focus algorithm is proposed to address this problem. First, a noise reduction ...
Railway infrastructures are among the most important national assets of countries. Most of the annual budget of infrastructure managers are spent on repairing, improving and maintaining railways. The best repair method should consider all economic and technical aspects of the problem. In recent years, data analysis of maintenance records has contributed significantly for minimizing the costs. B...
Much has been learned about the viscoelastic properties of the true vocal fold, including its linear and nonlinear viscoelastic properties under both tensile and shear deformation. Very little is known about the viscoelastic behavior of the false vocal fold, however. Clinical observations and computational modeling studies of phonation have suggested that the false fold could contribute to the ...
We study the relationship between potential equivalence and character theory; we observe that of a representation ρ \rho is deter...
Twist-weaving of kilim over the past centuries is preserved among the nomadic tribes of Kerman province, especially in Afshar tribe in Sirjan area and it has been used in decorating sofreh and salt bag. In recent decades, some changes are occurred in method of kilim weaving in this area and the "twist weaving" is used in all parts of kilim and has been famous as "Shirikipich Kili...
The idea of improving the energy output for small wind turbines without compromising remaining aspects technology, such as costs and structural integrity, is very appealing in context growing concern global warming goal providing electricity to remote isolated regions. This work aims contribute development distributed generation by exploring effects bend–twist coupling on performance a turbine ...
Passive stereo vision is proposed to work in a complimentary manner with active stereo vision for detection of smooth surfaces of deformed plates. Passive stereo vision is used to obtain the boundary of the smooth surfaces, whereas active stereo vision with the projection of structured light is applied to detect the details of the surfaces. An inherent problem in passive stereo vision, called f...
