Reasonable rock-explosive matching is of great important to the enhancing of explosive energy effective utilization and the improving of rock fragmentation effect. The traditionally emphasized method of acoustic impedance matching is not reasonable. Starting from the blasting breakage mechanism, a new method of rock-explosive matching in drilling and blasting is proposed. The new approach chooses explosive parameters by reasonable control of the size of crushed zone under the condition of fully fragmentation between adjacent balstholes. This method can intuitively reflect the blasting fragmentation effect and energy effective utilization, which is easy to implement. Also, a modified model is developed, with the combination of adjacent blastholes explosion load taken into account. As a result, explosive parameters for different grades of rock are given in full coupling on-site mixed explosive charge under different project objectives.

This paper proposed a speeding clustering algorithm of connectivity-credibility constrained random dispose which based on some other clustering algorithms. Simulation shows that this algorithm can get large cover of clustering, logical distributing and good stability. Comparing to the lowerst-ID clustering and highest-connectivity clustering algorithm, the algorithm can get less number of cluster-heads, more logical clustering, good communication between nodes and cluster-heads, steady networks, reduce communication cost of rebuilding, and can balance network's energy consume, prolong the networks life.

Accuracy Satellite Scanning Microwave Radiometer ocean parameters retrieval need brightness temperature of multiple channel from same area and identical resolution. Due to the limitation of spaceborne radiometer antenna design and feedhorn arrangement, each channel has different resolution and observation position, this will increase the ocean parameter retrieval error. Based on the HY-2 Scanning microwave radiometer antenna pattern and imaging geometry, we simulate the ground footprint form different channel, use Backu-Gilbert(BG) algorithm produce a single composite sample at a particular location and with a particular spatial weighting pattern from combination of the adjacent measurements, the low frequency 6.6GHz is set as the reference channel. The result showed that the matching with resolution decreasing could simulate the real instrument observation without introducing noise.

Strategic Study of CAE 2010, Volume 12, Issue 1, Pages 56-60
Traditional stereo correspondence algorithms rely heavily on the Lambertian model of diffuse reflectance. While this diffuse assumption is generally valid for most part of an image, processing of regions that contain specular reflections can result in severe matching errors. In this paper, we address the problem of binocular stereo dense matching in the presence of specular reflections by introducing a novel correspondence measurement which is robust to the specular reflections. Accurate depth can be estimated for both diffuse and specular regions. Unlike the previous works which seek to eliminate or avoid specular reflections using image preprocessing or multibaseline stereo, our approach works in its presence. Experiments demonstrate the effectiveness and robustness of our approach.

A Weighted Block-matching Criterion for the Hardware Implementation of Motion Estimators
Zhang Xia,Zheng Nanning,Zhang Guanglie,Wu Yong,Wang Shaorui,Xu Weipu
Strategic Study of CAE 2002, Volume 4, Issue 1, Pages 47-53
In all kinds of digital video processing algorithms, motion compensated algorithm can acquire perfect performance because the motion information in the video signal has been considered. The hardware implementation of the motion estimator is the core of the various motion compensated digital video processings, which will be applied in real systems. Block-matching motion estimating algorithm is widely used in real system because of its low computing complication, easy realization and high call frequency of the block-matching criterion in the hardware systems. A new criterion called weighted minimized maximum error is proposed in this paper. This criterion can reduce the complexity of the motion estimator, decrease the area of the hardware and increase the speed of the hardware. On the other hand, the criterion is suitable to be applied to the recursive searching strategy which has an inherent weakness called error propagation.

Improved Matching Algorithms for Linear Face Class Model
Fu Yun,Zheng Nanning
Strategic Study of CAE 2005, Volume 7, Issue 2, Pages 47-56
An advanced matching technique for linear face class model is proposed, which can solve the problem of detailed controlling and robust iteration for the realistic facial modeling. A new method——Dynamic Gaussian Pyramid Analysis (DGPA), which combines Non-Uniform Sampling (NUS) method and Multi-Resolution Analysis, is presented. Integrating the PS Sampling and the Cluster Random Sampling, the distribution of the sampled points in each level images of the Gaussian pyramid is adjusted dynamically. In coarse-to-fine scheme, the minimization algorithm is used to compute the near global optimal solution that may fit to yield accurate model matching. Dynamic adjusting the boundary of the sampling cluster area and the resampling ratio, the detailed representations are effectively controlled, and the model creation is quite robust. An improved Stochastic Gradient Descent (SGD) algorithm based on the Correlative Disturbance (CD) and Adaptive Learning Rate (ALR) is exploited to accelerate iteration convergence and compute valid model parameters. With the examples of MPI Caucasian Face and AI&R Asian Face databases, experimental results in subjective evaluation and objective evaluation demonstrate the advanced model matching technique.

Multifunctional fillers are greatly required for dental resin composites (DRCs). In this work, a spray dryer with a three-fluid nozzle was applied for the first time to construct high-performance complex nanoparticle clusters (CNCs) consisting of different functional nanofillers for dental restoration. The application of a three-fluid nozzle can effectively avoid the aggregation of different nanoparticles with opposite zeta potentials before the spray drying process in order to construct regularly shaped CNCs. For a SiO2–ZrO2 binary system, the SiO2–ZrO2 CNCs constructed using a three-fluid nozzle maintained their excellent mechanical properties ((133.3 ± 4.7) MPa, (8.8 ± 0.5) GPa, (371.1 ± 13.3) MPa, and (64.5 ± 0.7) HV for flexural strength, flexural modulus, compressive strength, and hardness of DRCs, respectively), despite the introduction of ZrO2 nanoparticles, whereas their counterparts constructed using a two-fluid nozzle showed significantly decreased mechanical properties. Furthermore, heat treatment of the SiO2–ZrO2 CNCs significantly improved the mechanical properties and radiopacity of the DRCs. The DRCs containing over 10% mass fraction ZrO2 nanoparticles can meet the requirement for radiopaque fillers. More importantly, this method can be expanded to ternary or quaternary systems. DRCs filled with SiO2–ZrO2–ZnO CNCs with a ratio of 56:10:4 displayed high antibacterial activity (antibacterial ratio > 99%) in addition to excellent mechanical properties and radiopacity. Thus, the three-fluid nozzle spray drying technique holds great potential for the efficient construction of multifunctional cluster fillers for DRCs.
