Seismic trace interpolation is necessary for high-resolution imaging when the acquired data are not adequate or when some traces are ***-onto-convex-sets(POCS)interpolation can gradually recover missing traces with an iterative algorithm,but its computational cost in a 3D CPU-based implementation is too high for practical *** present a computing scheme to speedup 3D POCS interpolation with graphics processing units(GPUs).We accelerate the most time-consuming part of the 3D POCS algorithm(*** transforms)by taking advantage of a GPU-based Fourier transform *** parts are fine-tuned to maximize the utilization of GPU computing *** upload the whole input data set to the global memory of the GPUs and reuse it until the final result is *** can avoid low-bandwidth data transfer between CPU and GPUs. We minimize the number of intermediate 3D arrays to save GPU global memory by optimizing the algorithm *** allows us to handle a much larger input data *** reducing the runtime of our GPU implementation,the coalescing of global memory access and the 3D CUFFT library provides us with the greatest performance *** results show that our scheme is 3-2. x times faster than the optimized CPU-based implementation,depending on the size of 3D data *** GPU computing scheme allows a significant reduction of computational cost and would facilitate 3D POCS interpolation for practical applications.

自适应遗传算法采用在遗传进化的过程中动态调整各种遗传参数和遗传算子的手段,以达到快速收敛同时避免早熟的目的。提出了并行多种群自适应遗传算法(PMAGA:Parallel Multi-population Adaptive Genetic Algorithm),通过对种群规模、交叉率和变异率等遗传参数的动态调整使算法在保持种群多样性的同时,提高收敛速度;重点针对自适应调整过程中带来的负载失衡,加入了相应的迁移策略。最后,给出了并行多种群自适应遗传算法与简单遗传算法(SGA:Simple Genetic Algorithm)和孤岛遗传算法(IGA:Island-based Genetic Algorithm)的收敛性能和并行性能比较。

In this chapter,we discuss about the full space and subspace methods for ill-posed image restoration *** restoration refers to minimizing the degradation which is caused by sensing environment,say CCD camera misfocus, nonuniform motion,atmospheric aerosols and atmospheric *** image restoration problems,a key matter is to solve a quadratic programming *** study numerical solution methods in full space by limited memory of BFGS method and the subspace trust region *** develop a novel approach for reducing the cost of sparse matrix-vector multiplication when applying the full space and subspace methods to atmospheric image *** the projection technique for the regularized convex quadratic functional is developed in the iteration for ensuring *** experiments indicate that these methods are useful for large-scale image restoration problems.

The fluid mechanics in the generation of hyper veloeity water jets, light oiljets and glycerin jets was studied. Framing high-speed photography and single-shot photography wereused to observe the jets directly. The purposes of this study is to investigate the disintegrationand atomization processes at the velocity of 2.m/s-3km/s as well as the auto-ignition andself-combustion of the light oil jets. Therefore, in the jet velocity measurement in addition to thehigh-speed photography, the results by other methods such as the laser beams cutting method and theshock wave detection using pressure transducers were also given. In the observation of the jetsevents, the illumination phenomenon was found, which may be regarded as the result of theauto-ignition and combustion of the light oil jets. Finally, the Munroe jet was studied.

This paper is a case study of the development of Koreaninvested Enterprises (KIEs) in Shandong Peninsular based on a field interview survey together with questionnaire survey undertaken in 1996 and 1997. An analysis to the motivate factors for Korean investment entering china and a general evaluation on the business environment of Shandong Peninsular in terms of Korean investment is given firstly. Then the present characteristics of KIEs is described from micro point of view, with focus on the linkage pattern of enterprises, aiming at elaborating the emerging pattern of the international division of labor between china and the R. Korea, and the role of KIEs to the local social and economic development of Shandong Peninsular.
