According to movement balancing and position control problem of Self Balancing Two Wheeled Robot, a method based on H∞ Robust Control was proposed. We apply it onto the MIMO nonlinear model of robot, and simulated it in the MATLAB environment The simulation results shows that the robot can be balanced in fixed position well by this method, and also it have the ability to anti interference. © 2016, Institute of Advanced Engineering and Science.

A verifiable quantum secret sharing protocol model is proposed based on entanglement swapping. The dealer communicates with the participants one by one. The detection pattern or information pattern are choosed by uniform distribution, until he can make sure the information safe to the participant, and then he communicates with the next participant. This agreement not only is to avoid eavesdropping outside, and it can prevent internal fraud, thus the accuracy and security are ensured for information sharing, the verifiable results are achieved. © 2016 Institute of Advanced Engineering and Science.

The data containing structural information is an important problem in the field of machine learning. Kernel methods is an effective technique for solving such problems. A combined dimension kernel method is proposed or graph classification in this paper. A two-dimensional kernel is first constructed in this method, and it incorporates one-dimensional information to characterize the molecular chemistry, and then a three-dimensional kernel is constructed based on the knowledge of molecular mechanics to characterize the physical properties of the molecule. On this basis, the kernel of different dimensions is integrated, and the quadratic programming problem with quadratic constraints is solved to obtain the optimal kernel combination. The experimental results show that the proposed method has better performance than the prior technology, and it outperforms the existing algorithm.. Copyright © 2017, IGI Global.

The technology of three-dimensional virtual form has been widely applied to the rheological forming process of aluminium alloy. However, there is still some insufficiency existing in the flexibility and threedimensional character of form. Therefore, it shall further improve the rheological forming system of aluminium alloy based on computer three-dimensional virtual form technology. This paper proposes a new method of software-accelerated rendering. It hierarchically extracts the scene detail and hierarchy from the concept. Moreover, it discusses the realisation of uploading cache and rendering of three-dimensional image to proper hardware platform. It uses the inherent coherence of smooth frame to accelerate the speed of image rendering and thus designs a set of fast and flexible rheological forming system of aluminium alloy.

University students are the backbone of social and economic construction of China, and institutions of higher learning play a dominant role in improving students' physical health. Along with development of China's educational undertaking, there has been a higher requirement of students' comprehensive qualities. However, the teaching quality and credit hours of physical education in many Chinese institutions of higher learning are worrying. Unhealthy lifestyles are impairing students' physical qualities. A series of health problems, such as myopia and obesity, are caused by lack of physical exercises. This paper conducts a questionnaire survey of students' physical functions and qualities, and finds out physical education classes and extracurricular physical activities are major sources of physical training for students in institutions of higher learning. Based on the survey results, corresponding interventions are proposed at an attempt to improve university students' physical health.

Under the new normal, in order to bring up more quality and innovative talents to serve social development and to improve the overall teaching quality, it is imperative for private institutions of higher learning to realize transformation and upgrade. Based on a systematic review of previous domestic research findings about transformation of private institutions of higher learning under the new normal, this paper conducts an in-depth analysis of challenges facing transformation of private institutions of higher learning. Concerning these challenges, approaches to promoting development of private institutions of higher learning are proposed from the perspective of building a new talent training mode, enhancing connotation construction, optimizing the faculty team and improving the internal governance system. It is hoped that this research can provide valuable references for transformation of private institutions of higher learning under the new normal.

Quantum-behaved Particle Swarm Optimization algorithm is analyzed, contraction-expansion coefficient and its control method are studied. To the different performance characteristics with different coefficients control strategies, a control method of coefficient with Q-learning is proposed. The proposed method can tune the coefficient adaptively, and the whole optimization performance is increased. The comparison and analysis of results with the proposed method, constant coefficient control method, linear decreased coefficient control method and non-linear decreased coefficient control method is given based on CEC 2005 benchmark function.

Hilbert Vibration Decomposition (HVD) is introduced to the voltage flicker analysis. When voltage flicker accompanies with high order harmonics, the instantaneous frequency of its analytic signal in principle consists of two different parts, power frequency and a rapidly varying asymmetrical oscillating part. The important property of the instantaneous frequency offers a direct way to estimate the power frequency using a low-pass filter and remove the high order harmonics without pre-treatment procedures. Corresponding voltage flicker envelope is estimated using synchronous detection. The HVD method does not involves basic functions that the wavelet transform method needs. It can also adaptively estimate the frequency and amplitude of every modulation frequency component. Simulation results prove that the proposed method could accurately detect voltage flicker with high order harmonics. It has higher calculation efficiency and detection precision than wavelet transform method. Experimental results show that the new algorithm is feasible and efficient. © 2017 Institute of Advanced Engineering and Science. All rights reserved.

As a newly proposed theory, compressive sensing (CS) is commonly used in signal processing area. This paper investigates the applications of compressed sensing (CS) in wireless sensor networks (WSNs). First, the development and research status of compressed sensing technology and wireless sensor networks are described, then a detailed investigation of WSNs research based on CS are conducted from aspects of data fusion, signal acquisition, signal routing transmission, and signal reconstruction. At the end of the paper, we conclude our survey and point out the possible future research directions. © 2014 IFSA Publishing, S. L.

In order to prevent images from unauthorized access and distribution, the images should be encrypted before transmitting to different customers. The traditional encryption algorithms such as RSA, DES and AES are not suitable for encrypting images due to their high computational complexity. To this end, this paper proposes a new image encryption algorithm that has a lower computational complexity. Compared to those traditional encryption algorithms, the proposed scheme can be considered as a lightweight encryption algorithm. © 2012 Springer-Verlag GmbH.
