  • Research on semantic association vector MSAV feature selection based on
           Sal-F algorithm
    • Authors: Jing Yan; Liguo Li
      Abstract: The traditional way of lexical interpretation is to use some words to explain other words. These semantic information cannot be used to solve the problem of natural language processing oriented to the physical situation. Based on this, this paper proposes a new method based on the feature vector Word semantic representation model and its corresponding learning algorithm Sal-F. This algorithm applies the idea of cross-scenario learning to the alignment of “word-shape features” and uses the result of feature selection under MSAV to construct a visual semantic model Lsm-G, A semantic dictionary based on graph features is constructed. Using machine-oriented evaluation method, the average selection accuracy of this algorithm is about 70%, and the accuracy of sentence selection is up to 16%.

  • Numerical simulation of twin-barge float-over installation on AQWA
           software
    • Authors: Aixia Cao; Song Sang; Jing Sheng; Shuainan Yu; Guomeng Zhang; Xiao Shi
      Abstract: Float-over installation for the deep water platform is widely used all over the world. As one of float-over installation methods, twin-barge float-over installation has become a hot topic for offshore platform installation for it’s being unlimited by size of platform opening and draught as well as being capable for installation of larger topsides. By using AQWA software according to characteristics of weight loading transfer during installation of topsides by means of twin-barge float-over and taking the model of Cell Spar applicable for reference establishes a hydrodynamic model of objective platform on different stages during the installation process. By two connection methods of rigid and hinge connection by using the AQWA-Drift software simulates the movement response of float-over barge, topsides and platform in an ocean environment. Movement characteristics of upper modules of Spar platform is analyzed in installation of twin-barge float-over by different connection methods on four aspects of contrast of relative motion between barge and platform, contrast of single floating body motion response upon rigid and hinge connection, contrast of stress status of joint touch point and contrast in stress of mooring rope. The conclusion is that when the environmental loading incidence is transverse, the relative motion between barge and platform is most intense during the upper loading of float-over barge’s transferring to main body of the platform by 50%. And it is obvious that two connection methods of rigid and hinge connection have a certain influence on roll motion response of barges. Meanwhile, the support reverses force and cable tension upon rigid connection is significantly greater than the ones upon hinge connection.

  • Iot based real time trafic control using cloud computing
    • Authors: M. Vardhana; N. Arunkumar; Enas Abdulhay; P. V. Vishnuprasad
      Abstract: The rapid increase in the number of vehicles has given rise to the traffic jam, which is a major problem these days. The effect of traffic jam also effects the operation of ambulance. To avoid the traffic jam for the ambulance, a new idea is developed. In this paper we propose a new concept to avoid traffic jam for the ambulance and thus saving the life of an individual. At first the ambulance is detected and the information about the arrival of the ambulance is sent to the next station. The ambulance will make siren only when it carries patient inside, so by detecting both the ambulance siren and the image taken from the acquisition device, the information is sent to the next point which is on the way to hospital. Announcement of the arrival of the ambulance is done. The CCTV camera is monitoring each vehicle on that road. If any vehicle doesn’t abide by the announcement done, the image of the vehicle will be captured, and then by using the acquired image the number plate will be tracked and will be detected automatically by image processing. The vehicle information is sent to the police station, to take the necessary action. Thus the traffic control can be done and the way is cleared for the ambulance and life is saved. The processing is done using MATLAB and is verified.

  • A novel short-term multi-input–multi-output prediction model of wind
           speed and wind power with LSSVM based on improved ant colony algorithm
           optimization
    • Authors: Jingxian Yang
      Abstract: The intermittency and uncertainty of wind power may pose danger on the safety on the power system, thus the research of wind speed and wind power prediction methods has been widely concerned. The keys of wind power forecasting are the forecasting model selection and model optimization. In this paper, the least squares support vector machine (LSSVM) is chosen as the wind speed and wind power prediction model and improved ant colony optimization (IACO) algorithm is used to optimize the most important parameters which influence the least squares support vector machine (LSSVM) regression model. In the IACO-LSSVM method, the kernel parameter σ and regularization parameter γ were considered the position vector of ants, the improved pheromone updating method is used to effectively solve the contradiction between expanding search and finding optimal solution. A multi-input–multi-output (MIMO) short-term wind speed and wind power forecasting model is built and applied in a wind farm of Gansu province in order to predict wind speed and wind power. For comparative study, PSO-LSSVM model and SVM model are used for forecasting. Prediction analysis results show that the IACO-LSSVM model can achieve higher prediction accuracy and confirm the effectiveness and feasibility of the method.

  • Human behavior recognition based on multi-feature fusion of image
    • Authors: Xu Song; Hongyu Zhou; Guoying Liu
      Abstract: Human behavior recognition has become one of the most active topics in computer vision and pattern recognition, which has a wide range of promising applications. In order to overcome the deficiency of single representation feature, a new recognition algorithm of human behavior based on multi-feature fusion of image and conditional random fields (CRF) is presented in this paper. The proposed algorithm consists of three essential cascade modules. First, AE features and RNN features were obtained by extracting the behaviors of the action by the recurrent neural network (RNN) and the AutoEncoder (AE), Then, feature similarity was introduced, the AE features and RNN features were fused to form a more comprehensive and accurate AE-RNN feature by using feature similarity. Finally, the multiple features were using for recognizing the human behavior of image by conditional random fields. The experimental results show that the proposed algorithm is effective and promising and has higher accurate recognition rate which can adapt to complex background and behavioral changes.

  • A simplified method for calculating surface stress of thick walled
           cylinder based on numerical calculation method
    • Authors: Gan Lin; Lu Ming; Tao Feng-he; Men Xiang-dong
      Abstract: The maximum compound stress in the thick wall cylinder is usually the key factor that causes the thick wall cylinder to crack. The existing calculation method for stress–strain under thermo-mechanical impact in thick wall cylinder is suitable for stress analysis in the thermo-elastic range. However, the compound stress of the thick wall cylinder under the thermoplastic condition cannot be well analyzed. In this paper, a method to calculate the compound stress of the thick wall cylinder under the effect of thermal–mechanical impact is proposed, based on the finite difference method and the ideal elastic–plastic model and the Mises yield criterion. This method solves the problem of the compound stress calculation to the tube wall under the thermoplastic condition, which change as a result of the combined effect of thermo-mechanical impact. The compound stress in the wall close to the bore surface at different times during shooting is calculated, taking the firing process of a gun as an example. The calculation results well explain the cause of the formation of the crack and the distribution characteristics of the crack in the bore surface.

  • Exploring eye-tracking analyses of EFL learners’ cognitive processing of
           reduced relative clause
    • Authors: Xuesong Zhai; Yan Dong; Shengfen Wang; Li Wang; Jing Yuan
      Abstract: Eye-tracking technique is regarded as a reliable sensitive measurement to detect the regulation of eye movements, from which the objective visual data could be detected to explain invisible cognitive behavior. This paper employed eye-tracking sensors to examine how learners process reduced relative clause (RRC) sentences. The current research recruited 60 college students from a Chinese university to read three different types of RRC exemplars: left-branching, center-embodied and right-branching, and the sentences of each type were inserted frequent and/or infrequent verbs. The eye trackers were utilized to capture their eyes movements, and the instant visual data including fixation duration, fixation count as well as the scanning path were collected, compared and analysed. The results indicated that learners had the highest cognitive load when processing the center-embedded type of RRC, followed by the right-branching type and the left-branching type. Additionally, when the participant’s cognitive load is at a high level, the influence of verb frequency tends to be diminished. Besides, the results also revealed that the focus on the key areas, such as the conjunction, played a critical role in sentence processing. Furthermore, there leave several valuable practical and theoretical implications for further research. Firstly, eye-tracking technology is an adaptability for the measurement of mental process, which provide visualized evaluation of human–computer interaction. Secondly, the cognitive load theory could be extended and further studied though biofeedback data in the future.

  • Knowledge representation framework of accounting event in corpus-based
           financial report text
    • Authors: Zhuoqian Liang; Ding Pan; Ruijing Xu
      Abstract: As the financial report has entered the “era of annotation” (Fan and Zhang in Contemp Accout Res 29(1):38–42 2012), and the length of the unstructured information in the financial report has far exceeded the financial statements. In order to carry on the automatic analysis and processing to the text information in the financial report with the help of information technology, a combination of the information extraction and XBRL technology is needed to carry on the structured research to the text information in the Chinese financial report (Heidari and Felden in Proceedings of 10th international conference on DESRIST, LNCS 9073, 2015). Based on a self-built Chinese enterprise annual report corpus, this paper studies the characteristics and patterns of the disclosure language of accounting events in Chinese enterprises’ annual reports, which can be examplified in the “related transaction events”. This paper summarizes an expression framework of accounting event knowledge. The study is expected to lay the foundation for the study of annotated textual information extraction and automatic generation of XBRL financial reports, which shall be helpful to improve the quality of financial data and information sharing.

With the advances of NFV and AI-based software-defined networks, dynamic network service demands can be flexibly and effectively accomplished by connecting multiple virtual network functions (VNFs) running on virtual machines. However, such promising technology also introduces several new research challenges. Due to resource constraints, service providers may have to deploy different service function chains (SFCs) to share the same physical resources. Such sharing inevitably forces the scheduling of the SFCs and resources, which consumes computational time and introduces problems associated with reducing the response delay. In this paper, we address this challenge by developing two dynamic priority methods for queuing AI-based VNFs/services to improve the user experience. We account for both transmission and processing delays in our proposed algorithms and achieve a new processing order (scheduler) for VNFs to minimize the overall scheduling delay. The simulation results indicate that the proposed scheme can promote the performance of AI-based VNFs/services to meet strict latency requirements.

  • Interior design and pattern innovation design study based on generic
           algorithm logistics information
    • Authors: Qi Zhu
      Abstract: Interior design takes up a very important role in art design. As one of the most important and general part of pattern design, flower pattern design has always been the theme to which people pay most attention. This article first states the adaptive genetic algorithm, and then builds curvilinear fitting method which is based on the adaptive genetic algorithm. Furthermore, the researchers did tests on the algorithm and got the result: using this method can make the initial design project vary, and offers an effective method for flower pattern innovation design. They also used fitting operation for image materials to provide the most direct linear materials for planners, and added ways to offer initial curves of pattern design.

  • Laser-based measurement for micro-unbalance of cylindrical rollers of the
           high-speed precision rolling bearings
    • Authors: Xin Sui; Chunyang Liu; Jishun Li; Yujun Xue; Yongjian Yu; Yong Cui
      Abstract: It is a stringent requirement for China to develop the technology on the measurement for the unavoidable micro residual unbalance of tiny cylindrical rollers of the high-speed precision bearings, which are widely equipped on high-end advanced equipment. During the measurement process, the vibration response excited by micro unbalance, which is easy to be messed up with background noise, is hard to be detected and a soft support mounting bracket is proposed to enhance the amplitude of vibration response, while maintaining the steady rotation of test roller. Accordingly, a dynamic model of both test roller and mounting bracket is constructed to analyze and simulate the vibration response. Furthermore, a μm level high precision laser-based non-contact measurement system consisting of a roller rotation drive system and a vibration signal acquisition system is developed to measure the synchronized vibration of the unbalance. Finally, by comparing experiment results of a standard roller with a special prepared unbalanced roller and comparing experiment results with simulated results, the validity of the proposed measurement method is verified.

  • Time orient LEAD based polling point selection algorithm for efficient
           data aggregation in wireless sensor networks
    • Authors: R. Yuvaraj; A. Chandrasekar; S. Jothi
      Abstract: Data collection is a problem of which a detailed and indepth study has been made. It is known for numerous approaches and a variety of measures and methods that have the objective of validation. The efficacy of data collection still remains a baffling issue and a challenging task. Algorithms do exist in this area, but each considers only either a single feature or few thereof. This paper presents a time orient location energy availability data rate (LEAD) based scheduling algorithm for the improvements of the performance of data collection in wireless sensor networks. The salient feature of this method is its scheduling the sensors for the polling point on the basis of energy and location of the sensor. The method involves the identification of sensors of a small number of which one of which is chosen as the polling point. Computation of the LEAD weight for the sensors of any region is made and a tiny set with higher LEAD weight is selected. The mobile collector selects the polling point based on the LEAD weight and only one visit is done for the polling point when it has enough score and that too in a periodic manner. Data collection is done on a route whose selection is based on energy, hop, reliable routing. This scheme has the specific advantage of improving data aggregation and network lifetime maximization.

  • Information classification algorithm based on decision tree optimization
    • Authors: Hongbin Wang; Tong Wang; Yucai Zhou; Lianke Zhou; Huafeng Li
      Abstract: With the rapid development of information technology, the efficiency of information management has drawn increasing importance with its broadening application. Hence, a new information classification algorithm has proposed in this paper so as to improve information management of the limited resources by reducing its complexity. However, ID3 algorithm is a classical and imprecise algorithm in data mining, because traditional ID3 algorithm selects the attribute that has the maximum information gain according to the data set as that of the split node. Then the data subset is further divided according to the number of attribute values, and the information gain of each subset is calculated recursively. Decision Tree Optimization Ratio is the core approach in this algorithm, whose basic ideas have been introduced and analysed, proving to be more complex. Therefore, the authors propose a relatively precise RLBOR algorithm which takes the number of nodes in the decision tree model into consideration. The experiment show more precise of RLBOR algorithm.

  • An intelligent reversible watermarking system for authenticating medical
           images using Wavelet and PSO
    • Authors: K. Balasamy; S. Ramakrishnan
      Abstract: This paper presents a novel medical image authentication system through wavelet decomposition and particle swarm optimization (PSO). First medical image is treated with wavelet transformation and another image is treated with tent map and a hash function to further protect the secret watermark. Tent map ensures the sensitivity towards changes in the initial value which, can better protect and encrypt the original watermark. The operations performed on the binary coded image are based on the encryption sequences generated from chaotic map. Particle swarm optimization (PSO) results in producing optimal balance between embedding capacity and imperceptibility by exploiting the image pixel correlation of neighboring pixels. The novelty of the proposed technique lies in its ability to create a model that can find optimal wavelet coefficients for embedding using PSO and also acts as an absolute feature for embedding the watermark. The proposed method is thus able to embed watermark with low distortion, take out the secret information and also recovers the original image. The proposed technique is valuable with respect to robustness, capacity and imperceptibility.
