Abstract:Some new types of coplanar transmission lines，rectangular microshield coplanar coupled lines [RMCCL]，coplanar coupled rectangular microshield lines [CCRML]，are proposed for MMIC applications，which are developed from the coplanar coupled lines [CCL]，coplanar coupled striphnes [CCS]. The analytic formulas are presented for calculating the quasi-static TEM parameters of these coupled lines by means of exact conformal mappling techniques. Numerical results are also presented to illustrate the properties of these coplanar transmission lines.

Abstract:Data association is the key problem in multitarget tracking in the cluttenenvi-ronments. Now the joint probabistic data association (JPDA) algorithms is known as a more effective method，but the cost of computation and memory for this algorithms is always so great that this method coit be wsed in the practical multiple target tracking (MTT) system. Therefore，it is necessary to search for a fast or approximations algorithms for the JPDA. Here we provide a group of algorithms that we have preliminarily proved effective in our relevant subject.

Abstract:Estimating motion parameters and spatial position of object is very important in target tracking and computer vision. The constraint for obtaining 3D motion and coordinates from a monocular image sequence is first presented and proved in this paper. With this contraint，a nonlinear recusive filtering algorithm for estimation 3D motion parameters and 3D spatial position of a point target from monocular images has been proposed.The performance of the proposed technique on simulated image sequence is also involved.

Abstract:Based on a self-organized probabilistic neural network (PNN) paradim, a parallel network can be used to sort data parameters into classes with high sorting accuracy and fragmentation. The PNN implements the statistical Bayesian strategy by computing a joint probability density over all input parameters to match a group of candidate data classes, the sorting is accomplished by assigning the inputs to most likely group with highest probabílity density estimate. Then the prospect of applying the self-organized PNN to ESM pulse data sorting will be shown，and a system including self-organized PNN and pulse repeating interval sorting will be discussed under the limited conditions of the sorting after lots of emulated experiments.

Abstract:In this paper we use the Scaled Serial Fraction (SSF) analysis to study the scalaility of three parallel sort algorithms and that of the algorithms on a hypercube architecture. The scalability is a very important metric for predicting the performance of a parallel algorithm of a parallel system if we consider a massively parallel system with thousands of processors. The condition is given under which the three parallel sort algorithms are all scalable and explain the applicability range of each algorithm. We show that by scalability analysis one is able to exhibit the essential properties of parallel sort algorithms in a massively parallel processing environment. Finally the computed results of the scaled serial fraction, the scaled efficiency and the scaled speedup are given.

Abstract:The temporal property and the grey property should be taken into account while designing security policy models; and the three aspects of security requirements of privacy，integrity，and availability of the system should be described in a policy. The Existing security policy models can not describe the temporal and the grey property,and they usually focused only on privacy or integrity. A dynamic grey temporal system (DGTS)and a grey temporal security policy specification language (GTSL) based on the dynamic semantics of DGTS are presented in this paper.

The synthetical evaluate model can be seen from the paper on opposite efficiency of BOAS.

The frequency-stabilized stability of system is more than 1.7×10^-9，when the sample time is 100ms，10ms and 1ms respectively. The key technology is given in the paper.

Abstract:One dimensional planar compression-shear loading acting on the materials，which were cohered to the bact of quartz pieces was realized by using Y-cut α quartz crystals with their linearly elastic anisotropic dynamic response nature. Electric-magnetic particle velocity method was adopted to measure the movement of particles on different places in the materials. In the experiments，two-wave construction of compression-shear waves that propagated into the materials were observed clearly，the longitudinal and transverse particle velocity histories reflected fetures of dynamic response of materials under compression-shear loading. These results agreed with that from theoretic estimates on the whole.

Abstract:Base on the classical problem of the theory of optimal stopping--the secretary problem，k-th choice problem is worked out (k managers choose k secretaries). The optimal stopping rule is given，and we proved that the optimal value of probability is the k-th item of Poisson distribution with parameter k, i. e. e^-kk^k/k!. It confirms the classical secretary problem with first criterion on the other hand.
