Abstract: By analyzing the control principle of distributed control systemon thedouble twister, this paper designed the human-machineinteractive system of double twister based on WinCE. After researching embedded WinCEOS and remote control based on Web servers, and designing the application programs for human-machineinteraction onembedded hardware&software platform, the intelligent control and remote control of double twister were realized. The experimental results show that the system can meet the requirement of double twister intelligent controlling, and is representative of a new height of double twister intelligent controlling.

Abstract: This paper presents a data fusion system of chess-playing robot based on SERCOS. Owing to the environment of Windows NT + RTX, especially the SERCOS bus interface card, the control system is excellent in real-time property, more importantly, the highly efficiency of data fusion and image processing is guaranteed and therefore the good interaction between people and robot is ensured.

Abstract: To replace human workers in dangerous environments or difficult-to-access places, climbing robots with the ability to travel on different types of surfaces (floors, walls, ceilings) and to walk between such surfaces were developed. The most important technology for a climbing robot is how to resist gravity, and adhere to surfaces. This paper presents mainly six types of adhesion technologies to ensure climbing robot sticks to wall surfaces: magnetic adhesion, vacuum suction techniques, attraction force generators, grasping grippers, bio-mimetic approaches inspired by climbing animals, and compliant electroadhesion, et al. Moreover, this paper represents advantages and limitations of adhesion technologies.

Abstract: The author carefully analyzed the theoretical basis and means with reading articles and books about the quantitative forecast for mineral resources evaluation.And completely summarizes the new theoretical frontiers, such as metallogenic series, metallogenic system, the origin of the model and so on, as well as about the methodology, gis, geochemical blocks and so on.

Abstract: In this paper, a method for the parallel operation of inverters in an autonomous microgrid system is adopted. This paper presents the resistive output impedance control scheme that allows multiple voltage source converters (VSCs) to operate in parallel in a VSC fed microgrid. The control loops are taking into account the special nature of a low-voltage microgrid, in which the line impedance is mainly resistive. In contrast with the conventional droop-control method, the proposed controller uses a virtual resistance without communication signals to achieve good power sharing, which is insensitive to line-impedance unbalances.

Abstract: The initial velocity of a projectile has great effects on the weapon performances and it influences firing accuracy. It is meaningful to know the motion of projectiles in after-effect period. This article studies the motion of the projectile by using a Six Degrees-of-Freedom rigid model and chimera method, which is suitble to simulate large-scale deplacemengt of projectiles. The results of the simulation show that the velocity of the projectile increases rapidly first and decreases slowly after reaching the peak value.

Abstract: This paper uses existing self-awareness technology and power management strategy to propose a new strategy for nanosatellite power management. We dynamically manage the power through the awareness of the target applications’ running state. Based on applications’ performance requirements we use DVFS to optimize power management. Finally, our strategy had helped to improve the power utilization rate of nanosatellite systems with expected performance.

Abstract: A novel harmonic control circuit based on the composite right/left-handed transmission lines (CRLH TLs) is presented to suppress the harmonic components of the dielectric resonator oscillator (DRO). Firstly, the principles of left-handed transmission lines (LH TLs) are introduced. Then, the design of the proposed harmonic circuit is presented and the simulated results are shown. The second- and third- harmonic components are suppressed, and the output-power at fundamental frequency has increased.

Abstract: A clear visualization program is to achieve the final design purpose by taking advantage of visual elements, such as color, line, space and etc. to convey the efficient information. This paper conducted research on the effective application of visual thinking on data visualization and proposed the correct methods to use visual imagery features and optimize visualization program to let creators use visual language and convey data content more accurately, and help users to understand information and make visualization content more efficient and profound.
