The invention provides a method for evaluating information safety risk based on interval number and ideal solution. The method comprises the following steps of establishing a new evaluation matrix form, wherein the rows and lines of the evaluation matrix are used for respectively expressing an expert set and a factor set; presenting the expert evaluation comments in the interval number form, and filling the matrix; in addition, introducing the index of correlation degree with the ideal solution, and sequencing the authority of the expert comments by technique for order preference by similarity to ideal solution; finally, performing compound operation on the factor evaluation computed by the comprehensive expert comments and the factor weight computed by the analytic hierarchy process, so as to obtain the integral comprehensive evaluation. The method has the advantages that a model for fuzzy comprehensive evaluation based on interval number is studied, the new single factor evaluation matrix form containing more information is proposed, the information involved in the evaluation process is furthest remained by the matrix, and the defect of losing of expert information of the existing model is overcome.

The invention discloses a cloud service trust evaluation method based on multi-parameter interval number multi-attribute decision-making. The method comprises the following steps: first collecting QoS index data in a multi-parameter interval number form, and listing a decision-making matrix, converting an index value in the multi-parameter interval number form into a binary connection number, and then normalizing the decision-making matrix according to the cost type and the benefit type to obtain a normalized decision-making matrix; secondly, determining the QoS index weight based on the unknown weight setting of the attribute weight of the connection number; and finally performing the cloud service trust evaluation by use of a principle value model based on the normalized decision-making matrix and the QoS index weight. By use of the evaluation method disclosed by the invention, the QoS index data is collected in the multi-parameter interval number form and then normalized so as to guarantee the reality and the objectivity of the data; the index weight is determined based on the unknown interval number multi-attribute decision-making method of the attribute weight of the connection number, thereby improving the objectivity of the decision-making; the cloud service trust evaluation is performed according to the principle value model, the time complexity of the evaluation method is lowered. The evaluation method disclosed by the invention has strong objectivity and practicability.

The present invention discloses a Laguerre output method for a rigid body space motion state. According to the method, three velocity components of a machine shaft system and a three-ary number form linear differential equations by defining the three-ary number; a Laguerre orthogonal polynomial is adopted to proximately and closely depict a rolling angle p, a pitching angle q, and a yawing angular velocity r; a state transition matrix of the system can be solved according to a manner of an arbitrary order keeper so as to acquire an expression of a rigid body motion discrete state equation, such that the singularity problem of the attitude equation is avoided so as to acquire the main motion state of the rigid body. According to the present invention, the three-ary number is introduced, such that the state transition matrix is the block upper triangular manner, and can be solved by reducing the order so as to substantially simplify the calculation complexity, and be easily used by the engineering.

The invention relates to a method for generating mutual random graphic groups among communication equipment and an application system. Graphics are coded into word groups, ninety thousand of word groups are formed through indexing, one byte and one byte index are required only to translate the word groups into character groups and a database with ninety thousand of groups of characters can be circulated. Firstly, numbers formed by 0 to 9 are downloaded, then three hundred of graphics corresponding to graphic codes are formed and finally ninety thousand of word groups are formed through graphic coding. Therefore, only numbers are downloaded and the downloading operation is rapid and convenient. Then, the numbers are translated into three hundred of graphic codes and the like. Finally, characters, programs and the like are formed through indexing. The method can be used for realizing the triple guarantees of security data such as programs, article confidentiality, passwords and the like, wherein the triple guarantees comprise that: 1) original numbers can guarantee that no original graphic code groups are imported incorrectly and cannot be translated; 2) the list of ninety thousand of word groups cannot be converted into the character groups when indexes do not exist; and 3) each character group consists of two characters, every two character groups are different combinations, the decoding of one graphic code is insignificant and the decoding is enabled to be more difficult by introducing multiple indexes. Since a graphic code group decoder is installed, in combination with original code bars and indexes, the downloading efficiency and the character translation efficiency are improved.

The present invention discloses a medical image segmentation algorithm used in a CT room. The segmentation steps of the algorithm are that: firstly, a CT image is segmented into different small areas via a watershed algorithm, then an average gray value of the small areas is mapped to a high dimension characteristic space according to a KFCM algorithm and by utilizing a Mercer kernel, so that the original characteristics which are not displayed in a watershed algorithm segmentation image are displayed. The algorithm comprises the following steps of (1) pre-processing an image, and carrying out the median filtering; (2) carrying out the watershed segmentation on the pre-processed image, and storing the label k of each small area; (3) calculating the average gray value x<k> of each area, wherein the average gray value x<k> represents a sample set of an input space, k =1, 2, ..., n, n is the area number formed after the image watershed segmentation; (4) selecting a classification number C, a threshold value epsilon and a fuzzy exponent m; (5) calculating a clustering center and a weighting matrix. The medical image segmentation algorithm used in the CT room utilizes the advantages of the watershed algorithm and the weighted kernel clustering, also greatly overcomes the disadvantages of the two algorithms.
