Abstract: In this paper, we highlight an intelligent system to properly construct a function between a pair of generalized-fractal spaces: the d -cube [0, 1] d endowed with its natural fractal structure, and the closed unit interval endowed with a natural-like fractal structure. Such a function allows the definition of space-filling curves by levels as well as the calculation of the box dimension of higher dimensional subsets through the box dimension of subsets on the real line.

Abstract: For multi-attribute decision-making (MADM) problems with temporal characteristics and attribute values of interval-valued intuitionistic normal fuzzy numbers, dynamic interval-valued intuitionistic normal fuzzy weighted averaging (DIINFWA) operators are presented, and their properties are proved. Since attribute weights and time weights have both been unknown in MADM problems, we propose a dynamic interval-valued intuitionistic normal fuzzy MADM method. In this method, a combination weighting method of gray correlation analysis and the maximum deviation method are used to solve for attribute weights, comprehensively considering the subjective experience of decision-makers and objectives of decision data; time weights are decomposed into time-constant and time-variable weight …vectors. We determine time weights using the time function, combining information entropy and a logistic function. According to the algorithm of interval-valued intuitionistic normal fuzzy numbers, decision-making information in different time sequences are aggregated using the proposed DIINFWA operators. We construct a dynamic interval-valued intuitionistic normal fuzzy comprehensive decision matrix and use the VIKOR (Vlsekriterijumska Optimizacija I Kompromisno Resenje) method to obtain the optimal solution. Finally, the feasibility and significance of the presented method compared to existing methods are verified through analysis of numerical examples. Show more

Abstract: Let G = (V , E ) be a connected graph. An edge set S ⊂ E is a 3-restricted edge cut, if G - S is disconnected and every component of G - S has at least three vertices. The 3-restricted edge connectivity λ 3 (G ) of G is the cardinality of a minimum restricted edge cut of G . A graph G is λ 3 -connected, if 3-restricted edge cuts exist. A graph G is called λ ′-optimal, if λ 3 (G ) = ξ …3 (G ), where ξ 3 ( G ) = min { | [ X , X ¯ ] | : X ⊂ V , | X | = 3 , G [ X ] is connected}. Furthermore, if every minimum 3-restricted edge cut is a set of edges incident to a set of three vertices, then G is said to be super 3-restricted edge connected or super-λ 3 for simplicity. Inverse degree of G is R ( G ) = ∑ v ∈ V 1 d ( v ) , where d (v ) denotes the degree of the vertex v . In this paper, we study the relation of inverse degree and super 3-restricted edge connected graphs. Show more

Abstract: Urban distribution is regard as a time- and labor-consuming logistics activity which is critical to the residents’ daily life and municipal administration. To address this challenging practical problem, a novel multi-objective location-routing problem with simultaneous pickup and delivery is proposed.

Abstract: The overturning stability issue of continuous girder bridges is critical so that it is necessary to obtain the true overturning stability performance. At present, the parameters uncertainties in the structure were neglected in the stability evaluation method of the long-span continuous girder bridges, which leads to the unknown safety level of the continuous girder bridges during the cantilever construction. Therefore, a calculating method for overturning stability safety factors of long-span continuous girder bridges in cantilever construction based on inverse reliability theory is presented in this paper. The proposed method is extended from the traditional deterministic form of safety factor, which …considered influence of uncertainty factors among structure parameters was used to obtain safety factors through target reliability index based on inverse reliability theory. Overturning stability safety factor of long-span continuous girder bridges in cantilever construction and parameter sensitivity were assessed using the proposed method, as well as the reasonableness of longitudinal overturning stability safety factors was discussed. The results show that parameter uncertainties have a major effect on overturning stability safety factors of long-span continuous girder bridges in cantilever construction, ignoring parameter uncertainties will result in overestimation of overturning stability safety factors of long-span continuous girder bridges in cantilever construction, reasonable safety factor should be obtained based on target performance. The sum of the self-weight of the travelling form and the pouring segment has the most significant effect on the safety factor. It’s critical to ensure a reasonable situation of the travelling form during the construction stage in case of falling. The resistant moment of the temporary support and the eccentric distance of the support also need to be handled carefully because of the remarkable effect. The proposed method is stable and reliable, which will be convergent to the same result from different initial value in spite of different iteration progress. Show more

Abstract: The traditional Gauss-Newton iterative method is highly dependent on the initial value when locating the multimode GNSS receiver. If the difference between the initial value and the true value is higher, the algorithm has the problem of increasing number of iterations, and the algorithm lacks the self main monitoring process of the GNSS receiver, which leads to a great reduction in the positioning accuracy. A high precision multi-mode GNSS positioning algorithm is proposed. It is based on the composition and working principle of multimode GNSS multimode receiver, and the pseudo distance positioning distance is obtained by using GNSS multi constellation …combined location algorithm. It uses a direct algorithm without initial value and iteration through the new algorithm of high precision positioning. After linearizing the pseudo range location distance equation, the user’s general position is calculated. After the pseudo range location distance equation is carried out in the general position of the user, the user’s position correction is calculated by weighted least squares, and the exact location of the user is obtained. The receiver autonomous integrity monitoring (RAIM) algorithm based on the least square residual method of GNSS receiver is used to realize the self-improvement monitoring of GNSS, and to further improve the precision of the multi-mode GNSS positioning algorithm. Experimental results show that the proposed location algorithm has high location accuracy and stability. Show more

Abstract: The small fillet aluminum alloy cavity is a typical structure. The analysis and experiment have been conducted on the chatter at the corner of the aluminum alloy during milling process, the results show that continuity changing of spindle speed acceleration and size effect (special ploughing effect) are the main factors of chatter. The Axial Depth of Cut–Spindle Speed Analysis Method is not effective to reflect the chatter, the previous experiments have proved this point. This study investigated the cutting chatter at the corner during the circular milling process by using a new polar coordinates geometric model. The mechanics of the …process are modeled by considering size effect, while regarding the ploughing effect as a new important factor. The chatter of circular milling is verified and tested both at the reduced speed of spindle and reduced feed per teeth. Acceleration of spindle speed can cause chatter and ploughing effect for enhanced chatter stability because the changed process damping occured at small size. Show more

Abstract: Through fuzzy membership function, the fuzzy algorithm of image boundary detection based on power function can transform ordinary space into generalized fuzzy space. However, the algorithm has a large amount of operation and slow speed, and it will lose the boundary information of some low gray value in the image, thus the quality of the image boundary detection is poor. Therefore, a bilinear fast enhancement fuzzy algorithm for image boundary detection is proposed in this paper. Based on the defined generalized fuzzy set GFS and the generalized fuzzy operator LGFO, the linear left half trapezoid fuzzy distribution function is first …used as the generalized membership transformation of the image.The general space of grayscale image is transformed into generalized fuzzy space, and then boundary detection algorithm based on bilinear fast image enhancement is used to transform color image into gray scale and transform to generalized fuzzy set. The generalized fuzzy operator LGFO is used to enhance the contrast of the generalized fuzzy sets. The generalized fuzzy set after the enhancement is transformed into an ordinary fuzzy subset. The boundary extraction is carried out for the ordinary fuzzy subset after processing, and the image boundary detection is realized. The experimental results show that the proposed algorithm greatly improves the speed and quality of image boundary detection. Show more

Abstract: In the past, intelligent system often realized reasoning operation by interpolation method for one-dimensional sparse rule base, and could not analyze fuzzy reasoning of multi-dimensional sparse rule condition, which greatly improved the error and volatility of reasoning results. Therefore, a multiple multi-dimensional fuzzy reasoning algorithm based on CMAC neural network weighting is proposed. Through the CMAC neural network, the influence weight of each variable is extracted. CMAC neural network is applied to train weights of multi-dimensional variables in multiple multi-dimensional fuzzy reasoning rules, and local correction weights are made, so that the weights of each modification are very few. After …fast learning, the influence weights of the multi-dimensional variables on the reasoning result are obtained. A multiple multi-dimensional fuzzy reasoning algorithm based on CMAC neural network weighting is applied to input the given neighboring rules into CMAC neural network, and the weights of the variables in the neighboring rules are obtained. According to the linear interpolation and the sequence of interpolation cardinal numbers, the influence weights of the variables in the observation value are determined. According to the linear interpolation reasoning method, a new fuzzy rule is constructed. Based on the approximation between the new fuzzy rules and the observed values, the similarity between the predicted values and the new fuzzy rules is constructed. The result of fuzzy inference is obtained according to the similarity. The experimental results show that the proposed algorithm has high reasoning precision and stability, and the practical application effect is good. Show more

Abstract: The traditional time series data clustering for landslide displacement prediction is based on Euclidean distance measure. The time series data is clustered by distance calculation of two vectors. The correlation between components is not considered. The multiple components with single feature will interfere with the clustering results, and the accuracy of clustering results is greatly reduced.

By reconstructing the phase space of the landslide displacement time series, the phase space transposed matrix is …obtained as the time series reconstruction matrix. After embedding dimension processing, the time series of landslide displacement is predicted by SVM data mining model. Dynamic time warping calculation is based on the correlation of time series sequence and the components. The local optimal solution is obtained by recursive search, and the whole curve path is obtained. Clustering calculation of time series data set is carried out by using hierarchical clustering algorithm according to bending path. The intelligent clustering results of time series data in landslide displacement prediction is obtained. Experimental results show that the proposed algorithm has better clustering effect and higher clustering accuracy. Show more

Abstract: In traditional multi-infeed AC/DC transmission systems, decentralized and coordinated controllers are usually used to achieve AC/DC transmission control without considering the state and output of the system. Therefore, it cannot reasonably regulate the state of output based on the demand of multi-target control, which leads to poor control effect and weak adaptability. Therefore, a multi- sliding mode adaptive fuzzy controller is designed for the multi-infeed AC/DC transmission system. When the controller is designed, the state equation and the output equation of the multi-infeed AC/DC transmission system are considered. Based on the three different design parameters and the multi-sliding mode surface …of the thickness of the saturated layer, the adaptive controller based on multi-sliding mode is designed. This controller is used to set up the dynamic characteristics of some observable measurements in the multi-infeed AC/DC transmission system. Based on the setting results, the results of the comprehensive decision of the system are obtained by the adaptive fuzzy controller. According to the results of a comprehensive decision, the disturbance degree of feedback point is judged. Through the fuzzy algorithm based onthe second component function, the weighting matrices of the output feedback gain matrix are modified, so that the optimal control feedback gain is variable gain, to ensure that the control effect of the system meet the multi-objective control of engineering, and realizing the multi-sliding mode adaptive fuzzy controller ofthe multi-infeed AC/DC transmission system. The experimental results show that the designed multi-sliding mode adaptive fuzzy controller has good control effect on multi-infeed AC/DC transmission system, and has strong adaptability, and it can improve the dynamic performance of the system.

Abstract: In traditional clustering algorithm, the number of classes must be set beforehand and it is difficult in setting parameters. For uncertain environment, the precision of clustering is low and the scalability is poor. To address these problems, a new fuzzy clustering algorithm for interactive multi-sensor probabilistic data is proposed in this paper. The optimal hierarchical fusion algorithm with no prior knowledge is used to sort the sensors used for fusion according to the quality and the importance of information. The fusion of the first layer is the fusion of probabilistic data of two interactive sensors. The fusion of the second …layer is the fusion of the fusion results of the first layer and the probability data of the other sensor to obtain the final fusion results. On this basis, the fuzzy C mean clustering algorithm is proposed to cluster the interactive multi-sensor probabilistic data. Wireless sensor networks are dynamic, and it is difficult to determine the number of classes beforehand. Subtraction clustering algorithm is used to adaptively determine the number of classes and the initial cluster center though building mountain function as the data density index. Thus, the convergence speed of the algorithm is accelerated and the local optimum is avoided. Experimental results show that the proposed algorithm has high clustering accuracy and good scalability.

Abstract: The traditional abnormal location algorithm ignores the uncertainty of wireless sensor networks, which is not suitable for practical applications, and has low accuracy of location. To address this problem, a new fuzzy weighted location algorithm for abnormal target in wireless sensor networks is proposed in this paper. For the characteristics of spatiotemporal association and association of non-spatiotemporal attribute, the abnormal target is identified by multi-attribute association algorithm. Considering that Bayesian networks can effectively express dependencies between variables, Bayesian networks are used to establish the dependency model of non-spatiotemporal attribute. The dependence structure of non-spatiotemporal attributes is obtained by structure learning. …The parameter learning of each node of the network structure is carried out to obtain the conditional probability table. The confidence degree of attribute association is used to judge whether the attribute association pattern of the point to be detected is an abnormal pattern. The abnormal target location problem is described. The coordinates of sensor node with abnormal target are identified by the weighted location algorithm. The circles with the centers of three points not on a straight line and the diameter of the signal intensity indicator distance are drawn to obtain the abnormal target position. The weights for weighted location are obtained by fuzzy algorithm. Experimental results show that the proposed algorithm has high accuracy of location. Show more

Abstract: When the current algorithm encrypts cloud computing user behavior data, it cannot effectively resist external attacks. When there are many feature data, the encryption performance is poor. To solve this problem, a secondary encryption algorithm for data based on coupled control game mechanism is proposed. The piecewise linear chaotic maps and Fibonacci sequence perturbations are utilized to obtain pseudo-random numbers and improve the key’s mapping space, and can effectively defend against threats and attacks. Based on the piecewise linear chaotic map encryption algorithm, the discrete chaotic integrated map encryption algorithm based on the coupled control game mechanism is adopted. After …group-based encryption, the user behavior feature data is mapped into the encryption source-optimization evolution structure, and encrypted mapping is performed piecewisely. The encrypted data is used as the seed-derived set in the coupled control game mechanism, and the competition mechanism is adopted to perform the second discrete chaotic optimization on the encrypted data. The encrypted data ciphertext with the lowest chaotic discrete coefficient and the best game performance is selected as the output results of the coupled control game. Experimental results show that the proposed algorithm can effectively improve the encryption performance and improve the operation security of cloud computing network. Show more

Abstract: At present, special domain image encryption and compression algorithms have problems such as poor encryption and image compression, long time consuming of encryption and compression, and no guarantee of image compression quality. In this regard, this paper proposes an encryption and compression algorithm for spatial domain image selection based on hyperchaotic system. The hyperchaotic Chen system is selected to decompose the dynamics of the hyperchaotic system. The decomposition result is replaced by image scrambling, and the chaotic sequence output from the hyperchaotic Chen system is preprocessed. The two groups of sequences are used to complete the image scrambling so that …the image is encrypted for the first time. The discrete cosine basis is applied to make sparse representation of the original image after scrambling. The partial Hadamard matrix, which is controlled by the Logistic chaotic map, is used as the measurement matrix in the compressed sensing, and the two-dimensional projection measurement of the image is done to complete the image compression. The hyperchaotic Chen system is used to cyclically shift the projection results to change the pixel value of the image, and the final cipher image is obtained. The experimental results show that the algorithm anti-attack coefficient is 0.99, the average compression time is 7 s, and the compressed image has high resolution and strong confidentiality. The proposed algorithm is superior to the current algorithm in security and other performance, and can provide support for this field. Show more

After the system is initialized, the robot starts to work according to instructions of the upper computer and enters the self-adaptive obstacle avoidance subroutine. In the …subroutine, the ultrasonic sensor scans the infrared sensor output at the corresponding position. After receiving reflection information of the ultrasonic wave, the counter is stopped, and reflection time of the ultrasonic wave is simply calculated and cached into the buffer, so as to determine whether there is an obstacle in front, and the result is fed back to the upper computer through the RS485 bus. If there is an obstacle, then the interrupt program will be called, and the electronic compass program is utilized to determine the direction to avoid the obstacle; if there is no obstacle, the robot will continue to move following instructions of the upper computer to complete the system software design. Experiments show that the average time to avoid obstacles using this system is 0.40 s, and the obstacle avoidance accuracy is high and the stability is good. Under the data comparison and analysis, the proposed system is obviously superior to current systems in the time-consuming and accuracy of obstacle avoidance, and has great reliability. Show more

To address this problem, a new intelligent re-recognition algorithm for specific ship target in busy waters under the actual scene is proposed in this paper. Combining the existing feature extraction model and graph model, the graph structure is used to describe the identity relationship between the samples. Two points with …side connections have the same identity label. Then the multi-layer graph structure is built. After obtaining the block of the divided area, the similarity between the two samples of the link is calculated and the weight of the edge is obtained. Labeled samples are built according to the selected initial area. The energy loss of the graph model is obtained by estimating the pixel likelihood energy function with different labels of pixels and areas. A graph structure is obtained by minimizing the energy loss, which is the intelligent recognition result of specific ship target. For the large-scale data, the problem of incremental processing is solved by incremental maintenance. Experimental results show that the proposed algorithm has high recognition precision. Show more

Abstract: Aiming at the problem that the active queue management algorithm can not explicitly control the queue length and the relationship between throughput and delay, a fuzzy information control algorithm based on Active Queue Management for digital substation communication network congestion is proposed. After packet grouping is entered into the router cache queue, the packets that first enter the cache area of the router are preprocessed, and the data packet is processed fairly by using the geometric distribution function. The combination of Smith predictive control and adaptive fuzzy control is used to compensate the network delay of packets, eliminate the negative …impact of time delay on active queue jitter and delay jitter, and control congestion according to fuzzy rules intelligently. The experimental results showed that the proposed algorithm can maintain smaller queue oscillations, especially when the network conditions change. It can effectively eliminate the impact of time delay on queue jitter and delay jitter, and improve the overall performance of the network. Show more

Abstract: At present, the intelligent control system of robots is closed, which has the disadvantages of poor fault tolerance, unstable operation and low positioning accuracy. Aiming at these deficiencies, a Petri net model of the intelligent control system for open architecture robots based on PMAC is designed. Starting from the kinematics of robots, the forward and inverse kinematics model of open architecture robots are established according to DH method; then the trajectory planning is performed from Cartesian space linear interpolation algorithm and circular interpolation algorithm respectively, and the basic function of robot path planning is constructed. Finally, a PMAC-based open architecture …robot intelligent control system is established. The control system adopts dual-microcomputer hierarchical control mode and modular structure design. Real-time communication between the upper computer and the lower computer can be realized by calling the Pcomm32 dynamic link library; based on the robot’s forward and inverse kinematics model and trajectory interpolation algorithm, the modular control software for the robot system is developed. The control software realizes functions such as security check, parameters setting, kinematics analysis, and teaching reproduction. Combined with the principle of hierarchical Petri nets, various modules of open architecture robot control system based on PMAC are modeled. Experiments show that the designed system runs smoothly, has high positioning accuracy, good openness and scalability. Show more
