A method, apparatus and computer program product for machine-based segmentation of the cardiac chambers in a four-dimensional magnetic resonance image data that contains at least short-axis cine sequences. The segmenting is based on temporal variations in the data set and on features extracted from the image data. In particular, the method and apparatus process the image data to automatically segment an endocard based on fuzzy object extraction and to automatically segment an epicard through finding a radial minimum cost with dynamic sign definition and tissue classification. In addition, image data is preferably preprocessed to eliminate high local image variances and inhomogeneity. The image data is also preferably processed to identify positions of a base slice, an apex slice, an end-diastole, an end-systole and an LVRV connection.

Method and apparatus for creating an electronic database of disambiguated entity mentions and relations from a corpus of electronic documents. The invention automatically extracts from the corpus of electronic documents mentions about entities (e.g., references to people, organizations or places), parses the entity mentions into “mention objects,” and executes a series of grouping, comparison and hierarchical fuzzy object clustering algorithms to cluster together in an electronic database all of the mention objects referring to the same entity and all of the mention objects (e.g. “people”) associated with each other by a relationship (e.g., “co-authors” or “family members”). The resulting electronic database of disambiguated entity mentions and relations, which may comprise, for example, an XML document, a relational database or hierarchical database, is structured to permit useful recordation, access, review and display of all of the mentions and relations associated with a particular entity or collection of entities.

The invention discloses a liver-clearing and vision-improving boxthorn leaf traditional Chinese medicine tea. The traditional Chinese medicine tea comprises the following raw material medicines in parts by weight: 10-30 parts of boxthorn leaf, 10-20 parts of polygonum cuspidatum, 10-20 parts of Chinese angelica, 10-20 parts of jasmine, 10-20 parts of radix ophiopogonis, 10-20 parts of codonopsis pilosula, 10-20 parts of schisandra chinensis, 10-20 parts of radix polygonati officinalis, 10-20 parts of cuscuta chinensis, 10-20 parts of wolfberry fruit, 10-20 parts of prepared rhizome of rehmannia, 10-20 parts of prepared fleece flower root, 10-20 parts of eucommia ulmoides, 10-20 parts of glossy privet fruit, 10-20 parts of rhizoma polygonati, 10-20 parts of white paeony root and 10-20 parts of semen cassiae. The boxthorn leaf is cool in nature, bitter in taste and non-toxic and has the effects of tonifying deficiency, replenishing vital essence, clearing away heat, quenching thirst, dispelling the wind, improving the vision, treating hot eyes and pain, treating heat toxin sore and the like, and by adopting a modern process, the boxthorn leaf tea making is systematically researched, the prepared boxthorn leaf tea is good in mouthfeel and high in aroma, does not have green odor and can be accepted by consumers. For the boxthorn leaf tea, traditional Chinese medicines with the effects of nourishing liver and kidney and mild in nature and flavor are added, and the tea has obvious effects on dry and unsmooth eyes and unclear and fuzzy object observation caused by liver-kidney deficiency and excessive eyes.

The invention discloses a distortion target identification and judgment method based on discrete orthogonal moments, which comprises the following steps of inputting a distortion image to be detected,and identifying and judging a distortion target according to matrix transformation of the discrete orthogonal moments of the distortion image; and giving an optimal order reference value participating in calculation according to the image parameters. Experimental results show that the method has stronger robustness, and has advantages in the aspects of fuzzy object judgment and identification ofsimilar and complex objects under a distortion condition; and the given optimal order reference values suitable for the images of different sizes give consideration to the requirements of reducing thecalculation amount and improving the robustness, and have a very good matching effect with newly proposed parameters.

The invention relates to a wind power generation vane-change fuzzy control method, which solves the problems of low control quality and low steady-state performance of a wind power generation unit system and belongs to the technical field of application of wind power generation. The technical scheme comprises the following steps of: adjusting the magnitude of a modifying factor according to a membership function of a fuzzy object to achieve an adjustment control rule; introducing a fragmentation biquadratic Lagrange interpolation algorithm of a binary function into a self-setting fuzzy controller to convert discrete control variables into continuous control variables, so that the output power of a wind power generation unit can be relatively accurately and quickly controlled; therefore, the adjusting dead zone and the offset of the controller are eliminated, and the control quality of the system is ensured. In the wind power generation unit, due to the application of a control algorithm in which the self-setting fuzzy controller is combined with the Lagrange interpolation algorithm, wind power can be more accurately controlled, so that the wind power generation unit can better meet the requirements of power grids; and intelligent control over the wind power generation unit has become one of mainstream development directions of the current wind power generation technologies.
