Abstract: This paper constructs the picking mechanical hand binocular vision hardware system. Using an internal and external parameters calibration method of separation. In the calibration process, with calibration planar pattern translatory manner, appropriate for extracting feature points in the calibration template, through experiment and calculation to obtain the accurate parameters of camera model; external parameters calibration is a reasonable selection of reference coordinate system, through experimental analysis to obtain the two cameras outside parameter model.

Abstract: In order to reduce the amount of data exchange in E-mail transmission process, a non-repudiation E-mail transmission protocol was proposed based on the digital signature technology. By using the formal analysis based on the extended strand space method, strict authentication and analysis were conducted for the security of data transmission and the identity of both the transmitter and receiver. Furthermore, the safety and effectiveness of this protocol were verified.

Abstract: This study aims to find out if the two students with multiple disabilities can learn to use standard keyboard and computer mouse with the intervention of newly developed software. With built-in On-Screen Keyboard (OSK), the user can key in commands by using a standard mouse. Without changing the conventional computer mouse and outward appearance, a new mouse driver program was designed, of which the scroll wheel became a key to quickly click on OSK. With this design, students with multiple disabilities can complete the task fast and correctly by sliding the mouse wheel.

Abstract: Anaglyph 3D is a low-cost and popular 3D display method, made out of a photo pair. With only one common camera, however, there are difficulties in capturing moving objects. We suggest using the light field camera, which can be exploited as a computational stereo rig, to capture image pairs simultaneously. A processing framework for making anaglyph 3D image is then proposed. The effectiveness of our proposal is verified visually by experiments.

Abstract: With the idea of binary search increasing mechanism of BIC algorithm, an improved BIC (IBIC) algorithm is proposed by adjusting the congestion window with information of packet-loss and data delay, the flow chart and some important parameters are presented, the IBIC algorithm is carried out in Linux kernel. Moreover, the Linux-based network testing platform is constructed by utilizing squid to transmit data from server to clients in gateway, and using WANem to simulate the situation of bandwidth, data dropout and delay. By testing and comparing the congestion control capability of IBIC with other main algorithms, the IBIC algorithm is proved to increase effectively the network communication efficiency.

Abstract: In order to more accurate detection of ECG signal and cost savings, this paper designed a set of ECG signal acquisition system based on Matlab. The system is composed of hardware and software. Hardware is made up of signal acquisition processing circuit and MPC82G516 microcontroller for AD conversion. The software mainly contains configuring Matlab serial to realize communication with MPC82G516 and uses abundant filter resources of Matlab to remove noise by differential, absolute value, smoothing and threshold selection algorithm of R wave detection, R wave peak provides the basis for calculating the heart rate. This paper uses Matlab friendly user interface for displaying received data to make the data more intuitive and read more easily.

Abstract: The application of cloud computing technology provides a new idea for the development of mobile learning.Based on the analysis of the advantages of cloud computing to support mobile learning, The paper presents a complete design and application of mobile learning system based on cloud computing ,effectively to promote independent learning and collaborative exchange of the students, but also to provide the reference for the solution of mobile learning system based on cloud computing.

Abstract: This article is an introductory study on extensive research and testing of visual spatial intelligence. Research respondents are students of technical universities with experience in spatial modeling on a computer. The aim of the research is to determine whether experience with spatial modeling is related to the level of spatial intelligence.

Abstract: This paper analyzes the feature and necessity of data migration, and summarizes the commonly methods for it. According to the business characteristics of housing fund, an architecture model based on data migration is designed, and the functional process, the format of data packet and data specification is described according to the architecture levels. After the migration application is built, the operation data of the system are analyzed and further suggestions are given.
