Acceleration(G), in physics, is the rate of change of velocity of an object. Advanced missiles are capable of generating the axial acceleration(Gx), the tangential acceleration(Gy) and the normal acceleration(Gz) during aerial combat manoeuvres, which has seriously threatened flight reliability. In order to improve the reliability of missiles, it is necessary to carry out acceleration tests on the ground. Testers usually separately simulate the acceleration with the centrifuge, but the complex effect of 3-axial accelerations can not be reflected. This paper introduces a new 3-axial centrifuge, which can effectively and synchronously simulate the 3-axial acceleration. The paper also designs the structure and the synchronization control system of the 3-axial centrifuge. At last, the paper shows the result of the simulation and the result shows that the system is reliable, and it's synchronization among 3 axial accelerations is very high. The analysis can also provide a reference for similar centrifuge designers.

The purpose of this work was to compare the electrical characteristic of iridium spark plug with the standard spark plug in order to accord with the conditions of general control signal operation of the standard spark plug ignition system. The required voltage and spark duration time are used for analysis. The data of this study were defining by charging time of ignition coil since 0.5 - 6.0 ms and spark gap at the 0.7, 0.9 and 1.1 mm respectively. That operated under the normal atmosphere. The experimental results indicated that the required voltage of iridium spark plug is lower than the standard spark plug from fully saturated charging time. When it is applied in the general system, the advance angle should be adjusted more advance about 4% and the lower voltage requirement of one lengthens the spark duration, that is not suitable for engine speed more than 24000 rpm.

We describe a robust method for automatically rectifying the main facades of buildings from single images taken from short to medium distances. This utility is an important step in building recognition, photogrammetry and other 3D reconstruction applications. Our main contribution lies in a refinement technique for vanishing point estimation and building line grouping, since both significantly affect the location and warping of building facades. The method has been shown to work successfully on 96% of images from the Zubud-Zurich building database where images frequently contain occlusions, different illumination conditions and wide variations in viewpoint.

This paper describes our efforts and plans to develop a Virtual Laboratory for the education in robotics and automation. These efforts are characterized by the need of blending R&A subjects into a traditional Computer Science curriculum, thus forcing a specific selection of development topics. In this context, the robotics Laboratory must provide basic as well as advanced experiments, to address the needs of students at different education levels. In this paper, we present the development of three main applications, to support control Systems and robotics classes, as well as thesis and dissertation research. Of particular interest is the effort in the area of teleoperation, preliminary to the opening, next year, of a new curriculum on Medical informatics, in which Computer Assisted Surgery will play an important role.

Cooperative encirclement in swarm robotics has become an active research field. How to find the target in advance through local communication is an important problem in cooperative encirclement in swarm robotics, because it can bring many important benefits, such as avoiding relying on global information, reducing communication load and completing the task faster and more efficiently. Unfortunately, many of the current researches are done without considering the global information or the local communication to find the target in advance, so it is difficult to achieve better practical results in the application of large-scale cooperative encirclement in swarm robotics. In order to solve this problem, a triangle antenna model and a local interaction strategy are designed. On this basis, a local communication algorithm is developed: antenna communication model algorithm, which is used to complete the task of cooperative encirclement in swarm robotics. In order to verify the feasibility of the antenna communication model algorithm and the effectiveness of the local interaction strategy, we present a scene based on the triangle antenna model for the cooperative encirclement of the local communication swarm robots, and carry out simulation experiments and comparative experiments. The experimental results show that the antenna communication model algorithm and the local interaction strategy can find the target in advance, and complete the task better and faster.

It is possible to reconfigure supply chains with less cost and time if we use the mobile-robot bin packing system. So, many companies attempt at adopting mobile robots as their new carrier in their own warehouse. However, it is difficult to utilize indoor service robots as a carrier due to the localization problem, the safety problem, and the narrow bin packing environment. So we propose a practically applicable solution technique for a multi-robot bin packing system in an automatic warehouse, which assures a reasonable safety, computation time and a real world application for more than 3 multi-robots. First, design criteria for out bin packing system are introduced. Second, we suggest some sketch of robot mechanical parts. Finally, the method of managing multi-robots in an automatic warehouse robot design with a collision motion planner is proposed.

A multi-person tracking method is proposed concerning how to conquer the difficulties such as occlusion and changes in appearance which makes algorithm hard to get the correct positions of object. First, we indicate whether the target is blocked or not, through computing the Reliability of Tracklets (RT) based on the length of tracklets, appearance affinity and the size. Then, we propose a "correct" observation sample selection method and only update the weights of particle filter when the RT is high. Last, the greedy bipartite algorithm is used to realize data association. Experiments show that tracking can be successfully achieved even under severe occlusion.
