An embodiment of the present invention is a method of shape forming vessels, the method comprising selecting a pathway to index the vessel across an operation wheel, indexing the vessel, controlling rotational indexing direction of the vessel across selected pathway, and operating on the vessel as the vessel is indexed across the operation wheel along selected pathway.Other embodiment include shaping by contouring length of the vessel, applying decoration to the vessel, wherein the decoration is added at a precise location based in part on reference to the registration spot, and using a controller to select the pathway based in part on desired shape of the vessel.

Disclosed are rigid random coils, having a contour length larger than a diameter thereof, an average bending ratio Db of 0.1˜0.8, and a weight average molecular weight of 1×108˜9×108 g / mole, and a resin composition or organic solvent composition including the same. The rigid random coils have the properties intermediate between those of polymers and rigid rod particles, and thus may be used as filler of various resins, aqueous solutions or organic solvents.

Described herein is a method of controlling soil moisture, water accumulation and fertilizer distribution in land. Elevation location data for land areas are extracted from two or more pixels of a topographic image including topographic data. Each pixel represents a land area. Wetness indices for the land areas are determined from the elevation and location data, based on the slope between two or more defined areas of land and an upslope contributing area per unit contour length. At risk defined areas of land, e.g., those at risk of accumulating water are identified based on wetness indices. Water is transported from the at risk defined areas of land to another location. The transporting of water reduces the risk of accumulating water in the at risk defined areas of land and improves crop growth potential in those areas.

The invention relates to a wireless sensor network routing method comprising the steps that multiple forward nodes and aggregation nodes of a current node are acquired; first distance, second distance and third distance are acquired; a contour curve is generated according to the first distance, the second distance and the third distance; the expansion and contraction rate, the contour length and the contour curvature of the contour curve are calculated; internal force parameters based on the expansion and contraction rate and the contour curvature are calculated according to the contour length, and external force parameters based on the network performance parameters between the current node and the forward nodes are acquired; resultant force parameters are calculated according to the internal force parameters and the external force parameters; and the next hop node is determined according to the resultant force parameters. Selection of the next hop node is enabled to be more reasonable, unnecessary energy loss can be avoided, network congestion can be effectively avoided and the network performance is enabled to be better.

The invention discloses a cloth clamping and aligning device. In order to overcome the defects that a lining and shell fabric are aligned inaccurately, and cloth is not suitable for volume production, according to the technical scheme, a lining clamping structure, a shell fabric clamping structure and a shell fabric closing structure are included; the lining clamping structure comprises a bottom plate for flatly laying the lining and a stabilizing piece for limiting the lining; the shell fabric clamping structure comprises a cover plate; the shell fabric closing structure comprises a driving assembly arranged on the cover plate and a moving assembly for driving the edge of the shell fabric to move; a first contour length is formed by the moving assembly, the moving assembly forms a second contour length after being driven by the driving assembly to move, and the second contour length is smaller than the first contour length, so that the edge of the shell fabric is driven by the moving assembly to be closed to be aligned to the lining. The cloth clamping and aligning device has the advantages that the position of the lining and the position of the shell fabric can be stably fixed, the edge of the shell fabric is evenly closed to be aligned to the lining, and high precision is achieved; the product quality can be effectively improved, time and labor are saved, and manpower cost is reduced.

The invention discloses an image identification method and device. The method comprises obtaining the gray level image in the characteristic region of paper currency to be detected; performing the binarization processing for the gray level image in the characteristic region to generate a binarization image; calculating the contour length of the binarization image and obtaining the contour coordinates of the binarization image; transforming the contour coordinates to corresponding polar coordinates and judging the currency value of the paper currency to be detected according the shape features corresponding to the polar coordinates. Through the above scheme, the currency value of the paper currency can be effectively identified according to the pattern in the characteristic region of paper currency with cost reduced.
