We develop 3D automatic feature construction system to efficiently quantify different types of the lower limb alignment and the hip fracture. This system has the potential to provide useful information regarding the risk of knee and hip osteoarthritis, and should be considered an alternative method for the measurement of the lower limb alignment and the hip fracture. Our newly defined parameters (hip-knee-ankle,...
Up to now, all the wavelet transforms are inner product representation of Hilbert space. In [1,2,3,4], based on the principle of mathematics and dialectical method, a novel method-VPWT (Vector Product Wavelet Transform) is proposed and studied, it is useful for wavelet theory and signal processing. In [5,6], vector wavelet functions, vector scaling functions and biased wavelet functions are put forward,...
In this paper, a disassembly sequence planning approach using an advanced immune algorithm is proposed. Firstly, an advanced support matrix is constructed to represent the stability of a product, by which the method to derive the stability of parts in the product is given, and this stability is considered as one of the evaluation objectives in disassembly sequence planning. Secondly, because the partheno...
With the growing demand for GNSS application, the satellite navigation payload may supply several signal components and modulation types in each frequency. This trend will continue for the future GPS/Galileo/Compass system. In order to provide a precision positioning service, the satellite navigation payload must supply a continuous, precise and high integrity signal. The signal quality is determined...
In this paper, we analysed the status of WLAN security. According to the weakness of the most common encryption protocols WEP and WPA, an attack algorithm named Predictive Judgment adapted to cloud computing environment was given. With comparing the attacking processes on cloud computing platform and traditional platform, we proposed that the attacks supported by cloud computing have become serious...
Sentence similarity computing based on the “HowNet” usually treats the optimal matches between the primitives or words as the basic computing unit, and the final results can be got through the weighted sum model. However, this approach often results in the information duplication and the irrational construction. For such problems, this paper calculates the similarity of sets through the statistics...
In this paper, the conjugate gradient method for solving unconstrained optimization problem is applied to linear equality constrained optimization problem. An attractive property of the proposed method is that the generated direction is always feasible and descent direction, and this property is independent of the line search used. Under mild conditions, we prove that the method with Armijo-type line...
A new nonlinear discrete inequality in two variables is discussed. It generalizes some known results and can be used as handy tool in the study of the existence, uniqueness, boundedness and many other properties of the solution of certain partial difference equation. An example to show boundedness of solution of a difference value problem is also given.
The lifting scheme provides us a powerful tool for constructing biorthogonal wavelets. Meanwhile, it is a new explanation of first generation wavelets, i.e., any first generation wavelets filter can be decomposed into some lifting steps. A method of decomposing biorthogonal wavelets filters into lifting steps by solving equations is presented in this paper. The lifting coefficients can be obtained...
A minimal residual algorithm based on the idea of the classical CG method for the inconsistent matrix equation AXB + CYD = E is constructed in this paper. By this method, the minimum norm least squares solution for anti-symmetric matrices can be obtained within finite iteration steps by choosing a special kind of initial iteration matrix when the matrix equation AXB + CYD = E is not consistent and...
Orchestra is proposed to change the traditional design process of routing protocols and it firstly introduces the concept of evolution into routing design. The disadvantage of traditional genetic algorithm, such as the bad searching quality and long computation time, makes the Orchestra has a bad performance and can not be applied to large scale network routing design. To improve Orchestra, a distributed...
Cormack classification is believed as a golden indicator for predicting tracheal intubation is difficult or not in clinic. Some anaesthetists usually estimate the airway state by examining single airway features. However, specialists agree that prediction accuracy of a difficult airway may be improved if multiple static and dynamic metrical airway features were considered. In this paper, we developed...
For the research of Chinese word segmentation, the BP algorithm model has a lot of defects such as low convergent velocity, easily falling into local minimum, low velocity and efficiency. In this paper, we proposed a new particle swarm neural network algorithm (NPSO-BP), and used it in Chinese word segmentation. The results show that the speed of the segmentation algorithm is obviously faster than...
In this paper we propose a web log mining-based network user behavior analysis scheme, which plays an important role in network structure optimization and website server configuration. Based on clustering and regression model, we studied the network user's visit model in a university by analyzing a large amount of web log data which is collected from the university campus network. The data analyzing...
As energy crisis poses a huge threat to human welfare, the electric vehicle is of vast potential for future development as an newly emerged traffic tool which is energy-conserving and environment-protective. However, the layout method of its charging station is far from a mature system even though the construction is being undertaken. Thus this paper presents a multi-objective planning model which...
To realize high speed and high precision positioning for photolithography, a novel scheme of six degree of freedom magnetically levitated precision positioning stage is designed, where 8 air core solenoid coils and 32 permanent magnets are employed as the stator and mover respectively, and the levitation and linear drive parts of the stage are separated, thus the coupling between them is minimized...
