Based on the traditional smart card grey lock method, the card can't be traded after grey lock. The paper put forward a new method to support once pre-freezing mechanism. The terminal can pre-freeze part of the money in card according to its actual situation, used to complete the corresponding business. User can take away the card after grey lock, and operate the balance in card except pre-freezing money, with loading, unloading, purchasing and so on financial transactions. It ensures that the card after grey lock can be finished a normal trading demand. So the method improves the convenience for using card.

Traditional smart card patch is processed in the place where main command accepts. This patching method has the shortcomings of low efficiency and long time to execute. The paper proposes a new mechanism for patching ROM smart card APDU commands. The user can patch instructions for APDU commands according to their needs and redesigned APDU commands. It will go to the new designed instruction to execute from an already well masked ROM program. Then new demanded functions are implemented. The method solves the problem of patching functions on masked ROM card.

For the future wireless networks, heterogeneous data traffic services, i.e., variant bit-rate (VBR) service and constant bit rate (CBR) service are needed to be supported. The optimal power allocation algorithm for the non-orthogonal AF (NAF) Relays-assisted multicast transmission, which may be suitable for the VBR service, has been investigated in [2]. However, the power allocation algorithms for the cases of CBR service and heterogeneous data traffics service are not considered. In this paper, a power allocation problem is addressed by considering the heterogeneous data traffic with VBR and CBR services in the uplink data transmission, where Different from assumption of infinite length of spreading code in [2], a finite length of spreading code is considered and the interference among the signals from mobile terminal and relays exists. And then, an optimal power allocation algorithm is proposed by solving its inverse problem. Simulation results demonstrate the efficiency of the proposed algorithm.

Images taken by different sensors at different time instant with different resolutions are formulated by state space models, and are fused by use of Multiscale Kalman Filter(MKF). The effectiveness of the presented algorithm is shown by comparing it with the wavelet based method through experiments, where four performance measures are used. The performance evaluation indices are the root mean square errors(RMSE), the information entropy(Entropy), the space frequency(SF) and the space visibility(SV). Theretical analysis and experimental results show the effectiveness of the presented algorithm.

Conventional long baseline interferometer based Direction of Arrival (DOA) requires multi-group long baselines and short baselines to deblur. In this paper, only using the time difference of arrival (TDOA) data of long baseline interferometer can cancel the debluring shortage and achieve high-precision DOA estimation. Meanwhile iterative filtering algorithm is adopted to extract high-precision changing rate of phase difference from the fuzzy phase difference data of long baseline. Combined with the measured DF and the change rate of phase difference, particle filter algorithm is utilized to achieve high-precision single-station passive location. Parameter measurement and the distribution of location error are verified through theoretical simulations. And the simulation results demonstrate the efficiency of the single-station location method based on long baseline interferometer.
Due to wide frequency band, the long-distance communication is prone to be jammed by traditional radios. Furthermore, severe interference will lead to serious deterioration of performance. To solve this problem, the p...

As to the real-time positioning demands for micro assembly process, this paper proposes a way which is based on Relevance Vector Machine Regression (RVMR). It solves the low efficiency problem which usually accompanies other common regression algorithms because the regression pattern is not sparse enough. This paper brings out grading RVMR, adopting the thought what is called "From coarse to fine". In this way, the number of training samples is greatly reduced while guaranteeing precision. So the off-line training efficiency is improved, meeting various parts in micro assembly process. In this algorithm, the algebra feature of the part image is extracted as the RVM's input, using Principal Component Analysis (PCA). Experiments on many regression algorithms and grading RVMR are both carried on. The results show that RVMR gets the shortest measuring time and the highest accuracy. The single axis estimation precision of part attitude is better than 0.5°.
