The invention discloses a document flow information processing method and a device based on a format file and particularly discloses the following technical proposal: the file flow information of theformat file is acquired, which is the file content structure information in the format file and / or the file layout self-adaptive presentation information in the format file; the file content of the format file is divided into content blocks according to the acquired file flow information; the content block division result information of the format file is described; the file flow information basedon the format file after content block division is described, according to the content block division result information. Therefore, the file flow information for describing the format file is more practical and applicable, and any content of the format file can be flexibly described in file flow information, with more accurate description scope; besides, the file flow information processing is more flexible and simplified.

The invention discloses a dynamic consistency control method in a massive data environment, comprising the following steps of: (1) carrying out initialization work on an environment by a main thread; (2) starting to monitor a read-write request, which is sent by a client-side, by a service node; (3) when the service node receives a data read-write request task sent by the client-side, firstly reading an operation type of the request task; (4) reading a deviation type of the request task and reading a deviation value of the request task; comparing a read result with an existing threshold value and then putting the read result to the tail part of a corresponding array; and (5) returning back to the step (2) and continuously monitoring requests sent by the client-side. According to the dynamic consistency control method provided by the invention, the difficulty that an existing key assignment type database cannot be used by different applications due to the difference between consistency requirements of service data can be overcome. Therefore, a user only needs to care about indexes and values of operated data to the consistency and does not need to spend a great deal of efforts to redevelop one set of the key assignment type database which only meets own service requirements.

The embodiment of the invention discloses a creation method for an information system. The method comprises the following steps of: receiving a service request message from a user, wherein the service request message comprises the type of the information system to be created and the required contents of the information system of the type; retrieving a meta database according to the type of the information system to be created and the required contents of the information system to obtain metadata in line with the type and the required contents, wherein the metadata is used for describing a service entity; resolving the metadata, and acquiring service entity data from a service entity database according to the resolved metadata; and creating the information system according to the service entity data. The embodiment of the invention also discloses a creation device and a creation system for the information system. According to the technical scheme, the expansibility of the information system can be enhanced, and the overall creation efficiency of the information system is improved.

The invention discloses a commodity image classifying method based on complementary features and class description, comprising the following steps of: firstly, taking the classified image as a training sample; secondly, carrying out the resolution compression on all marking image class and test pictures by using a picture batch editing tool; thirdly, extracting the complementary features of towertype gradient direction histograms and tower type key word histograms of the pictures in various marking images; fourthly, extracting the features of the tower type gradient direction histograms and the tower type key word histograms of images of commodities to be classified; fifthly, constructing a class descriptor of each marking image class; and sixthly, classifying the obtained feature vectors by using a nearest neighbor classification algorithm, calculating the distance between the images of the commodities to be classified and various marking image class descriptors and using the image class with the shortest distance as the classification result. According to the invention, two complementary features can be fully utilized and the classification result is more accurate by using the nearest neighbor classification algorithm based on the image-class distance.

The invention discloses a method for judging the stability of an uncertain networked multi-time-delay system, which establishes a closed-loop networked multi-time-delay control system model, and maps the uncertainty of the closed-loop networked multi-time-delay control system into a convex polyhedron parameter space to obtain Convex polyhedral uncertain networked multi-delay control system model; based on the constructed Lyapunov function, use the free weight matrix method to judge the delay-dependent robust stability of the convex polyhedral uncertain networked multi-delay control system, and obtain the delay correlation Sufficient conditions for robust stability. The invention avoids using the same Lyapunov function for all vertices of the convex polyhedron in the uncertain space, and reduces the conservatism of the sufficient condition for robust stability.

The invention belongs to programmable component structure technology field, specially a local programmable logic array wiring resource structure and modeling method which supports the crutch line. The wiring resource structure of the invention includes: programmable interconnected line, uniform switch matrix, input and output multi path selector array and logic unit. It breaks the limit of level and uprightness interlinkage resource, introduces the concept of crutch line, makes the wiring path not pass the programmable switch, it gives attention to speed and agility. The description of wiring line resource, the interconnected line is distributed to the repeated unit then integral interconnected resource is described by describing an interconnected line resource in a repeated unit. This describing method is very flexible, the kind, amount, proportion of interconnected resource can be changed conveniently, and any switch array can be generated.
