This study aims to identify the principal components in ten prevailing factors, which would account for the influence of major economic variables on electricity consumption. Principal component analysis on these variables suggests two principal components, which respectively have Eigen-values of 8.28 and 1.04 and a cumulative variance of 82.77% and 93.19%. The regression results between electricity...
The high-altitude long-range gliding UUV is a new conception UUV which includes unmanned aerial vehicle technology and unmanned underwater vehicle (UUV) technology. This paper simulated the three-dimensional flow field of the high-altitude long-range gliding UUV considering its aerodynamic layout using the software Cart3D, which is based on Euler equations. Then the result was amended with a consideration...
