励磁功率柜智能均流暂态过程分析

分析和研究了智能均流时晶闸管换流的暂态过程,重点对并联整流桥同号桥臂晶闸管间的换流过程进行了理论分析和实验研究.结果表明,触发在先的晶闸管会率先完成相间换流,触发在后的晶闸管则会在已经导通的同臂号晶闸管之间进行分流;相间换流速度快,幅度大,同臂号晶闸管间的分流速度慢,幅度小;无论导通时刻是否一致,同臂号晶闸管的关断截止时刻总是相同的.得出了智能均流是通过改变同臂号晶闸管的触发时刻,进而改变其导通初期的电流幅度和通流宽度来实现均流目的的.指出了智能均流技术在励磁功率柜中应用时需注意的问题.     

Pose measurement using quaternion and Kalman filter

In this paper, a method combining perspective-n-point （PnP） and novel iteration algorithm is developed to measure the pose of a target in high precision for Tele-LightSaber game. The PnP algorithm is used to obtain a rough pose, which is taken as the initial value of the iteration algorithm. The iteration algorithm utilizes the unit quaternions to represent the rotations. Then the result is optimized with Kalman filter. Considering the real-time and accuracy of the pose measurement, a fast feature extraction algorithm including object location, edge detection and corner detection is adopted to get the corners in high precision. The experiments and results verify the effectiveness of the proposed method.     

Reusing Test Cases Based on the Function Point

Reusing test cases from existing test case library is quite common in the software testing field. Testing practice tells us that there is a strong relationship between the granularity of a function unit under testing and that of the test case. A function unit with small granularity usually results in the test cases with the same small granularity. Therefore a test case defined as the function point,i. e.,the smallest size function unit,was provided for the first time.Though test cases with smaller granularity usually have better reusability,the cost of accurately reusing and integrating such test cases is also higher. In order to balance the test case reusability and the cost of test case reuse,a novel test case reuse model based on the function point was proposed in this paper. In this model,a reusable test case for specification-based testing was defined and some reuse strategies and three formal reuse methods were given. Finally,the complete automatic software process was realized by a reusing generation tool. The new method has improved reuse accuracy,while greatly enhances the software productivity.
