The multifunction treadmill from the rack, motor, adjustable power, running belts and instrument control panel composition, in order to ensure that the entire system stability and damping effectiveness of the system, the base frame all welded structures. Stent design is divided into two parts by plugging in the form of installation and removal, use of ABS plastic front and rear covers, analyzes and running with running board design, and wriggled plate design. The basic function of the treadmill is to build a movement track (treadmill belt), direction of movement of the runway and the movement of the running in the opposite direction, but the speed must be automatically aligned, so that makes movement to exercise jogging in place. Achieve treadmill features for running belt drive with speed control: usually a DC motor drives, DC motor through a semiconductor power device, using pulse width (PWM) control method to achieve speed. © (2014) Trans Tech Publications, Switzerland.

Security issues are paramount in wireless networks even more so than in wired networks. A particularly devastating attack in wireless networks is the wormhole attack, where two or more malicious colluding nodes create a higher level virtual tunnel in the network, which is employed to transport packets between the tunnel end points. These tunnels emulate shorter links in the network in which adversary records transmitted packets at one location in the network, tunnels them to another location, and retransmits them into the network. Our focus in this paper is to analyze the performance of reactive multicast routing protocol On Demand Multicast Routing Protocol (ODMRP) under the influence of worm hole nodes under different scenarios and design a Worm Hole Secure ODMRP (WHS-ODMRP) by applying certificate based authentication mechanism in the route discovery process. The proposed protocol reduces the packet loss due to malicious nodes to a considerable extent thereby enhancing the performance. © 2011 IEEE.

ZnO thin films with different thickness (the sputtering time of AlN buffer layers was 0 min, 30 min,60 min, and 90 min, respectively) were prepared on Si substrates using radio frequency(RF)magnetron sputtering system. X-ray diffraction (XRD), atomic force microscope (AFM), Hall measurements setup (Hall) were used to analyze the structure, morphology and electrical properties of ZnO films. The results show that growth are still preferred (002) orientation of ZnO thin films with different sputtering time of AlN buffer layer,and for the better growth of ZnO films, the optimal sputtering time is 60 min. © (2014) Trans Tech Publications, Switzerland.

Cloud computing is to take the Internet technology as the main processing capacity of information technology to integrate. Its purpose is to realize the expansion with great scale and offer service to multiple external customers, which can make different application systems be able to obtain computing power, storage space and software service in accordance with the requirements. In the whole process of designing the teaching, the creation of educational environment should be paid attention to, which has a huge role in giving full play to the educational function of cloud computing can help learners effectively learn and use cloud computing resources. This paper mainly starts from the relationship of cloud computing and education and proposes a concrete design scheme of cloud computing network teaching platform. © 2015 Taylor & Francis Group, London.

Streaming media technology is also known as streaming media technology. Users can experience playing while downloading function, which improves the transmission speed of multimedia information on the internet. In this paper, we use streaming media technology, combined with the parabolic interpolation and Newton interpolation algorithm, design multimedia interactive platform of the college students' ideological and political education and comprehensive education. The overall structure of the platform is composed of multimedia, streaming media distribution equipment, school network, clients of teachers and students. On the internet between the teachers and students, student and students they can communicate ideological and political. In order to test the performance of network, we use the iperf software to test packet loss rate and delay characteristics of the network. The results show that Newton interpolation method has better delay characteristics, parabolic interpolation algorithm has low packet loss rate. It provides technical reference for the application of multimedia technology in the ideological and political education. © (2014) Trans Tech Publications, Switzerland.

BBS's speech in the public opinion has great impact on students' emotion. If we can regulate public opinion of university BBS of, and deal with the speech with cross impact on students' moral emotion timely, which can make the BBS having good cross and the interaction impact on students' ideological and moral emotion. In this paper we use the MyEclipse5.1 version to expand the public opinion module of the forum, and use with chasing method to calculate the value of object function in the network public opinion evaluation, and join the moral evaluation module in the network architecture. The main function of this module is to optimize the evaluation process of the forum, realize the real-time evaluation of network public opinion, and eliminate the negative cross influence of network evaluation on students' moral emotion. © (2014) Trans Tech Publications, Switzerland.
