Blade element momentum (BEM) theory with airfoil data is a widely used technique for prediction of wind turbine aerodynamic performance, but the reliability of the airfoil data is an important factor for the prediction accuracy of aerodynamic loads and power. The airfoil characteristics used in...

Fabrication of structures on the micro- and nanometer scales is of great importance for both fundamental research and potential applications. While microlithography methods are relatively established, the production of multi-component micro- and nanostructures with high density still presents...

Based on regional characteristics of Xiangtan City and in line with relevant principle of overall coordination of urban and rural land use, this paper builds an evaluation system for overall urban and rural land use in Xiangtan City. With weight of each index determined by Analytic Hierarchy...

Nansha District in Guangzhou, south China, as a well-known rapid urbanization area, is characterized by the widely distributed soft soil prone to land subsidence. Accurate monitoring of surface deformation plays a significant role for the hazard prevention and mitigation. In this study, 21...

To control quality in supply chain, this paper presents multi-period, dynamic game models in principal-agent theory, which are opposite to static, single period game models. The research comes from industrial practice and the conclusions are more operational and feasible in theory. Finally, the...

A novel nanofabrication method that combines both "bottom-up" (template-assisted peptide self-assembling) and "top-down" (replica molding) techniques is introduced. A designer peptide, GAV-9 (NH2-VGGAVVAGV-CONH2), can epitaxially self-assemble into nanofilaments on the surface of mica, which is...

Recently, gold nanoparticles (AuNPs) were reported to increase the specificity and efficiency of the polymerase chain reaction (PCR). In this paper, we tested the enhancement of AuNPs with five different sizes on the specificity of two-round PCR. The results showed that, except 5.02 nm AuNPs,...
