A system and method for creating a combined or mixed-energy image using both low- and high-energy CT data sets acquired using a dual-energy CT system. The low- and high-energy datasets are mixed using desired weighting factors to mimic a “single-energy” image. The low-energy dataset provides data with improved contrast enhancement, but with increased noise level. The high-energy dataset provides data with lower contrast enhancement, but with better noise properties. By combining the low- and high-energy datasets in accordance with the present method, the resulting mixed-energy images utilize the information of full dose of radiation used in the dual-energy scan. A plurality of weighting metrics can be selected, including patient size, dose partitioning, or image quality, to determine the desired weighting factors based on the weighting metrics. By selecting the proper weight factors, image noise can be reduced and/or the contrast to noise ratio can be increased in the mixed-energy image.

A golf club shaft is 35-50 percent lighter than a conventional shaft while maintaining the outer diameter and structural characteristics of conventional shafts. The shaft has at least four layers of fiber reinforced material. The fiber reinforced layers are from innermost to outermost: a first angled layer; a first straight layer; a second angled layer; and a second straight layer. The angled layers are formed by bonding together two materials, each with fibers aligned in different directions. The second angled layer maintains the proper strength and rigidity of the shaft while keeping the shaft as light weight as possible. Aligning the second layer's fibers at an angle of 35-75 degrees with respect to the longitudinal direction of the shaft ensures proper weight and strength characteristics of the shaft. The resulting shaft is light-weight and exhibits the flexural rigidity, flexural strength, torsional rigidity, torsional strength, and crushing strength of conventional shafts.

In this application, the invention is a novel heuristic mechanism of working path and backup path reservation for highly utilizable WDM mesh networks, which we call dynamic-network adapted cost selection (DAC-selection) mechanism. One of its characteristics is simple traffic distribution mechanism, and the performance of DAC-selection mechanism is superior to that of Random selection (R-selection) and Advanced Combined Min-cost selection (ACM-selection) mechanism. DAC-selection mechanism provides simple cost function by assigning proper weights to each component of the cost function and the total cost is obtained by just summing up the individual cost. Therefore, it is possible to select a best pair of working path and backup path which consumes least wavelength for reservation.

The invention relates to the technical field of keyword query search, in particular to a fuzzy keyword query method and a system based on weighing edit distance. The traditional information retrieval system asks users to provide a precise query word to search a result. The existing fuzzy retrieval system overcomes the shortage and can carry out fault-tolerant search. But the systems do not consider the situation that bigger input fault probability happens between adjacent key characters and shape similar characters when returning results are sorted, thereby greatly lowering user degree of satisfaction. Thus, the invention provides the weighing edit distance to measure the adjacent key characters and the shape similar characters and improves proper weight for the similar matching keyword which conforms to the two situations so as to enable the keyword to rank in the more front position. Based on the weighing edit distance, the search algorithm provided by the invention adopts Trie tree structure and has the characteristics of real time and interaction. The invention can more effectively return data queried truly by users and improves user degree of satisfaction.

A differential motion conveyor drive includes at least three pairs of drive shafts carrying eccentric weights that are selected to correspond to the terms of a Fourier series in order to achieve optimal conveying speed and efficiency.
