特征捆绑的3 种多项式模型比较——位置不确定理论

正确捆绑的概率随着靶子与非靶子间距离的增加而增加，亦即错误的特征捆绑是由对特征位置知觉的错误造成的，这是位置不确定理论的一个重要观点．通过对特征捆绑的3种多项式模型对比，我们认为，位置不确定模型可以排除错觉性结合实验中的猜测成分，用数学参数精确地估计真正错觉性结合发生的概率，对错觉性结合的测量效果最佳．它不仅修正了传统的错觉性结合数据分析方法的不足，同时也是对特征整合理论的重要补充．

Fast VLSI Implementation of Modular Inversion in Galois Field GF（p）

Modular inversion is one of the key arithmetic operations in public key cryptosystems, so low-cost,high-speed hardware implementation is absolutely necessary. This paper presents an algorithm for prime fields for hardware implementation. The algorithm involves only ordinary addition/subtraction and does not need any modular operations, multiplications or divisions. All of the arithmetic operations in the algorithm can be accomplished by only one adder, so it is very suitable for fast very large scale integration (VLSI) implementation. The VLSI implementation of the algorithm is also given with good performance and low silicon penalty.     

GPS/INS integration: A performance sensitivity analysis

Inertial Navigation System (INS) and Global Positioning System (GPS) technologies have been widely used in a variety of positioning and navigation applications. Both systems have their unique features and shortcomings. Therefore, the integration of GPS with INS is now critical to overcome each of their drawbacks and to maximize each of their benefits. The integration of GPS with INS can be implemented using a Kalman filter in such modes as loosely, tightly and ultra-tightly coupled. In all these integration modes the INS error states, together with any navigation state (position, velocity, attitude) and other unknown parameters of interest, are estimated using GPS measurements. In a high performance system it is expected that all these unknown states will be precisely estimated. Although it has been noted that both the quality of the GPS measurements and the trajectory and/or manoeuvre characteristics of the problem will have impacts on system performance, a systematic sensitivity analysis is still lacking. This paper will address this issue through real data analyses. The performance analysisresults are very relevant to system design and platform trajectory and/or manoeuvre optimisation.
