That is,the truth value of an implication compound proposition is just the compatibleness degree of the actual implication degree or implication rate between its sub-propositions with the language value that describes the feature of implication relation in this compound proposition.

The key technique in the MUSIC algorithm is the signal subspace extraction which can be found from the eigen decomposition of the sample covariance matrix of the antenna receive signal. The eigen value decomposition of a Hermitian matrix is implemented by using the QR algorithm, and the signal subspace is constituted by collecting the significant eigen vectors.

To solve this problem, an algorithm which can adaptively determine the double thresholds based on gradient histogram and minimum interclass variance and improve Canny operator was proposed. Theory and experiments show that the proposed algorithm is effective and correct.

By means of the numerical methods, the root of the resonance frequency equation is solved, and by means of Ansys software and the finite element method, the torsional vibration mode of the thin ring is analyzed, and the academic value and the simulant value of the resonance frequency are compared.

The left singular vector of the projection has been tracked by the projection approximation subspace tracking algorithm. Then the modal parameters are obtained by least square method. At last an experiment is made using a cantilever beam to prove the efficiency and stability of the method by changing the frequency band of the exciting signal.

The numerical calculation commonly used for the Delphi process more than 100, including solutions of linear algebraic equations, interpolation, numerical integration, special, function approximation, eigenvalue problems, data fitting equation Root and solve nonlinear equations, functions and the extreme optimization, statistical data description, Fourier transform spectra, solution of ordinary differential equations reconciliation partial differential equations.

Stack will be the first to use infix form of the formula into the form of the suffix and then form the basis of the suffix from the beginning of leaf nodes corresponding binary tree structure Finally after by traversal of the tree, and the value of the subtree, that is, for every arrival a node, the value of its sub-tree has been calculated, when the reach the root node, the obtained value is the formula of true value.

First,the determinant is regarded as a function of or- der n and denoted by D;Second,the determinant is expanded by row or by column,then the relation in both of Dand subdeterminants will be examined in details to set up certain a recursion,generally speaking,it must be a homogenous or a non homogenous recursion;fi- nally the coefficients of the general solution are found out with the aid.

The crossover operation in the traditional GA operating is that choose two chromosome cross only at random also you can cross a bit, match and cross partly, cross order and cross cycle etc.
