Flow visualization is an important research field in scientific visualization and feature detection is the one of the core problems. This paper presents a novel approach for complex ocean flow visualization and analysis by applying the helmholtz-hodge decomposition theory to the feature extraction problem. We give an efficient implementation on regular grids by solving a large-scale sparse group of...
Tension feed-forward control method based on filament deform is presented in terms of filament tension generation theory. Tension control integrated system of six-axis filament winding machine is set up. Through motion analysis to non-geodesic windings for revolution object and control of resin's temperature, the equation of filament tension according to extension length is established, thus improves...
A compact wideband microstrip filter using a folded multiple-mode resonator is proposed. The filter contains only one resonator, which operates as not only a resonant element but also an open stub. The filter simultaneously realizes a broad passband, a compact size, and two transmission zeros at both the lower and upper stopbands. The transmission zero mechanism is investigated in detail through the...
In the chaotic local adding-weight linear method, Euclid distance is used as correlation measurement between phase points. Because Euclid distance just indicates space distance between phase points, the inherent relevant information can not be mined adequately, so that the enhancement of forecasting precision is restricted. The article uses the angle between vectors as phase points' correlation measurement,...
