On the basis of EST (Equivalent STate hashing) algorithm, this paper researches a kind of test generation algorithm based on search state dominance for combinational circuit. According to the dominance relation of the E-frontier (evaluation frontier), we can prove that this algorithm can terminate unnecessary searching step of test pattern earlier than the EST algorithm through some examples, so this algorithm can reduce the time of test generation. The test patterns calculated can detect faults given through simulation.

A variety of studies on Stereo Matching Algorithms present that the process of Stereo Matching Algorithms can be reduced to five stages. The core three stages of Stereo Matching Algorithms are the attainment of initial match cost, the generation of candidate match cost and parallax calculation. Based on this theoretical, the grading test platform for stereo matching methods was present, on the context of using vc++6.0 to realize class encapsulation in each stage. There are four kinds of image to control data stream and unified interface between classes in this platform. Testing platform was divided into three parts - area of images-displaying, area of time-displaying and area of parameter-input In the images-displaying area, different parameters can be selected to control the execution of different algorithms. In the time-displaying area, the length of time of different algorithms can be compared, meanwhile, the bottleneck to improve the real time of algorithms can be detected. Performance-checking experiments of the test platform show it is excellent;its structure is clear;its function is perfect;its operation is simple;its expansibility is good.

We report a novel anti-resonant hollow-core fiber(ARF) with a heptagonal core surrounded by connected cladding tubes,which is employed as a laser beam mode shaper. Cladding nodes are formed between each pair of adjacent cladding tubes,which efficiently enhances the mode coupling, thus significantly suppressing higher-order modes(HOMs) within a short fiber length. Numerical investigation and simulation for variations in the curvature of each node are conducted, through which an optimized structure of cladding nodes is obtained. Experimental results demonstrate that for a 1-m-long ARFbased mode shaper, the output beam quality M2is enabled, and the near-diffraction-limit beam quality is 1.03. The ARF presents a maximum average transmission power of 600 mW, achieving a total coupling efficiency of approximately85%. Moreover, it is maintained for one hour without inducing any damage while maintaining beam quality. These results highlight the great potential of the mode shaper in applications such as laser surgery, precision welding, and laser writing.

The queuing performance of the cross-layer system with Space-time block code (STBC) over Multi-input-multi-output (MIMO) channel is analyzed. The Adaptive modulation and coding (AMC) in physical layer and finite length of buffer in data-link layer are combined with this model. A simple cross-layer design and the queue state process are proposed based on finite state Markov channel model, which is to solve the service process. The proposed cross-layer design is also incorporated with STBC to further improve the system performance. Simulation results illustrate the dependence of system performance on various parameters, and quantify the performance gain due to cross-layer optimization. The adjustment of target packet loss rate of adaptive modulation coding in physical layer can maximize average throughput of the system, meanwhile a significant improvement of the system performance is brought.

In recent years, Compressed Sensing(CS) has been a hot research topic. It has a wide range of applications, such as image processing and speech signal processing owing to its characteristic of removing redundant information by reducing the sampling rate. The disadvantage of CS is that the number of iterations in a greedy algorithm such as Orthogonal Matching Pursuit(OMP) is fixed, thus limiting reconstruction ***, in this study, we present a novel Reducing Iteration Orthogonal Matching Pursuit(RIOMP) algorithm that calculates the correlation of the residual value and measurement matrix to reduce the number of *** conditions for successful signal reconstruction are derived on the basis of detailed mathematical *** compared with the OMP algorithm, the RIOMP algorithm has a smaller reconstruction error. Moreover, the proposed algorithm can accurately reconstruct signals in a shorter running time.
