[Applications] t_direct_decon DL : 0: tsint.f90 Generates and writes a set of synthetic seismic traces that are read by the t_direct_decon.f90 code. The synthetic data is composed of 10 traces of 1000 samples, with a multiple of period p=200 samples, and reflection coefficient c=-0.5. This periodic reflectivity is convolved with a minimum-phase wavelet of 10 samples forming a synthetic trace that is replicated 10 times to generate the input matrix. For the single-channel example no noise is added to the synthetic data. For the multi-channel example a little noise is added to prevent instability in the algorithm, once the multi-channel algorithm fails because two or more channels are equal. The input data matrix is stored in direct access format in the input_panel.dir file. t_direct_decon.f90 Main code, reads and deconvolves data stored in the input_panel.dir file. The output is stored in direct access format in the deconvolved.dir file. The input and output data are also stored in a ASCII format in the in_out.dat file.-T_direct_decon is a Fortran 90 program for performing direct multichannel predictive deconvolution.

[Applications] SVSLMS DL : 0: 本程序提出了变步长自适应滤波算法的步长调整原则:即在初始收敛阶段或未知系统参数发生变化时,步长应比较大,以便有较快的收敛速度和对时变系统的跟踪速度而在算法收敛后,不管主输入端干扰信号v ( n) 有多大,都应保持很小的调整步长以达到很小的稳态失调噪声. 根据变步长公式编的程序，很有参考价值. -This procedure, a variable step adaptive filter algorithm step adjustment principle: that in the initial convergence phase or unknown system parameters change, the steps should be relatively large in order to have fast convergence speed and time-varying systems tracking speed in convergence, no matter the main input interference signal v (n) how much should be adjusted to maintain a small step to achieve a small steady state misadjustment noise. compiled according to the formula variable step procedure useful reference.

[Applications] poisson_nlmeans DL : 0: An extension of the non local (NL) means is proposed for images damaged by Poisson noise. The proposed method is guided by the noisy image and a pre-filtered image and is adapted to the statistics of Poisson noise. The influence of both images can be tuned using two filtering parameters. We propose an automatic setting to select these parameters based on the minimization of the estimated risk (mean square error). This selection uses an estimator of the MSE for NL means with Poisson noise and Newton’s method to find the optimal parameters in few iterations(An extension of the non local (NL) means is proposed for images damaged by Poisson noise.)

[Applications] fluent DL : 0: 通过对渐扩管流动特性的理论分析与试验研究，其结果发现：渐扩管元件对管道和系统的作用不仅和全身尺寸有关，而且也和安装位置有关。设计不合理的渐扩管使管道系统产生再生气流噪声，同时使管道系统气流引起更大脉动，造成整个系统振动，利用Fluent软件仿真分析为渐扩管的合理设计提供了可靠的参考资料，具有重要的工程应用价值。(Through the theoretical analysis and experimental study of the flow characteristics of the diffuser, it is found that the effect of the diffuser on the pipe and system is not only related to the overall size, but also related to the installation position. The unreasonable design of diffuser causes the noise of regenerative air flow in the pipe system, and makes the air flow in the pipe system more pulsating, causing the vibration of the whole system. The simulation analysis by Fluent software provides reliable reference for the rational design of the diffuser and has important engineering application value.)
